Daratumumab.
Description
DARZALEX FASPRO is available as a colorless to yellow, clear to opalescent, preservative-free solution for subcutaneous administration.
15 mL vial: Each single-dose vial contains 1800 mg daratumumab (120 mg/mL).
Daratumumab is an immunoglobulin G1 kappa (IgG1κ) human monoclonal antibody against CD38 antigen, produced in a mammalian cell line (Chinese Hamster Ovary [CHO]) using recombinant DNA technology.
Recombinant human hyaluronidase (rHUPH20) is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously. It is produced by mammalian (Chinese Hamster Ovary) cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). It is a glycosylated single-chain protein with an approximate molecular weight of 61 kD.
Excipients/Inactive Ingredients: Recombinant human hyaluronidase (rHuPH20), L-histidine, L-histidine hydrochloride monohydrate, L-methionine, polysorbate 20, sorbitol, water for injection.
Action
Pharmacotherapeutic group: Antineoplastic agents, monoclonal antibodies. ATC code: L01FC01.
Pharmacology: Pharmacodynamics: DARZALEX FASPRO subcutaneous formulation contains recombinant human hyaluronidase (rHuPH20). rHuPH20 works locally and transiently to degrade hyaluronan ((HA), a naturally occurring glycosaminoglycan found throughout the body) in the extracellular matrix of the subcutaneous space by cleaving the linkage between the two sugars (N-acetylglucosamine and glucuronic acid) which comprise HA. rHuPH20 has a half-life in skin of less than 30 minutes. Hyaluronan levels in subcutaneous tissue return to normal within 24 to 48 hours because of the rapid biosynthesis of hyaluronan.
Mechanism of action: Daratumumab is an IgG1κ human monoclonal antibody (mAb) that binds to the CD38 protein expressed on the surface of cells in a variety of hematological malignancies, including clonal plasma cells in multiple myeloma and AL amyloidosis, as well as other cell types and tissues. CD38 protein has multiple functions such as receptor mediated adhesion, signaling and enzymatic activity.
Daratumumab has been shown to potently inhibit the in vivo growth of CD38-expressing tumor cells. Based on in vitro studies, daratumumab may utilize multiple effector functions, resulting in immune mediated tumor cell death. These studies suggest that daratumumab can induce tumor cell lysis through complement-dependent cytotoxicity (CDC), antibody-dependent cell-mediated cytotoxicity (ADCC), and antibody-dependent cellular phagocytosis (ADCP) in malignancies expressing CD38. A subset of myeloid derived suppressor cells (CD38+MDSCs), regulatory T cells (CD38+Tregs) and B cells (CD38+Bregs) are decreased by daratumumab. T cells (CD3+, CD4+, and CD8+) are also known to express CD38 depending on the stage of development and the level of activation. Significant increases in CD4+ and CD8+ T cell absolute counts, and percentages of lymphocytes, were observed with DARZALEX FASPRO treatment in peripheral whole blood and bone marrow. T-cell receptor DNA sequencing verified that T-cell clonality was increased with DARZALEX FASPRO treatment, indicating immune modulatory effects that may contribute to clinical response.
Daratumumab induced apoptosis in vitro after Fc mediated cross-linking. In addition, daratumumab modulated CD38 enzymatic activity, inhibiting the cyclase enzyme activity and stimulating the hydrolase activity. The significance of these in vitro effects in a clinical setting, and the implications on tumor growth, are not well understood.
Pharmacodynamic effects: Natural killer (NK) cell and T-cell count: NK cells are known to express high levels of CD38 and are susceptible to daratumumab mediated cell lysis. Decreases in absolute counts and percentages of total NK cells (CD16+CD56+) and activated (CD16+CD56dim) NK cells in peripheral whole blood and bone marrow were observed with DARZALEX FASPRO treatment. However, baseline levels of NK cells did not show an association with clinical response.
Immunogenicity: In multiple myeloma and AL amyloidosis patients treated with DARZALEX FASPRO subcutaneous formulation in monotherapy and combination clinical trials, less than 1% of patients developed treatment-emergent anti-daratumumab antibodies.
In multiple myeloma and AL amyloidosis patients, the incidence of treatment-emergent non-neutralizing anti-rHuPH20 antibodies was 7.1% (58/812) in monotherapy and combination DARZALEX FASPRO clinical trials. The anti-rHuPH20 antibodies did not appear to impact daratumumab exposures. The clinical relevance of the development of anti-daratumumab or anti-rHuPH20 antibodies after treatment with DARZALEX FASPRO subcutaneous formulation is not known.
Immunogenicity data are highly dependent on the sensitivity and specificity of the test methods used. Additionally, the observed incidence of a positive result in a test method may be influenced by several factors, including sample handling, timing of sample collection, drug interference, concomitant medication and the underlying disease. Therefore, comparison of the incidence of antibodies to daratumumab with the incidence of antibodies to other products may be misleading.
Cardiac electrophysiology: Daratumumab as a large protein has a low likelihood of direct ion channel interactions. The effect of daratumumab on the QTc interval was evaluated in an open-label study for 83 patients (Study GEN501) with relapsed and refractory multiple myeloma following daratumumab infusions (4 to 24 mg/kg). Linear mixed PK-PD analyses indicated no large increase in mean QTcF interval (i.e. greater than 20 ms) at daratumumab Cmax.
Clinical studies: Clinical experience with DARZALEX FASPRO subcutaneous formulation: Monotherapy-relapsed/refractory multiple myeloma: MMY3012, an open-label, randomized, Phase 3 non-inferiority study, compared efficacy and safety of treatment with DARZALEX FASPRO subcutaneous formulation (1800 mg) vs. intravenous (16 mg/kg) daratumumab in patients with relapsed or refractory multiple myeloma who had received at least 3 prior lines of therapy including a proteasome inhibitor and an immunomodulatory agent or who were double-refractory to a proteasome inhibitor and an immunomodulatory agent. Treatment continued until unacceptable toxicity or disease progression.
A total of 522 patients were randomized: 263 to the DARZALEX FASPRO SC formulation arm and 259 to the IV daratumumab arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median patient age was 67 years (range: 33-92 years), 55% were male and 78% were Caucasian. The median patient weight was 73 kg (range: 29-138 kg). Patients had received a median of 4 prior lines of therapy. A total of 51% of patients had prior autologous stem cell transplant (ASCT), 100% of patients were previously treated with both PI(s) and IMiD(s) and most patients were refractory to a prior systemic therapy, including both PI and IMiD (49%).
The study was designed to demonstrate non-inferiority of treatment with DARZALEX FASPRO SC formulation versus IV daratumumab based on co-primary endpoints of overall response rate (ORR) by the IMWG response criteria and maximum Ctrough at pre-dose Cycle 3 Day 1 (see Pharmacokinetics as follows). The ORR, defined as the proportion of patients who achieve partial response (PR) or better, was 41.1% (95% CI: 35.1%, 47.3%) in the DARZALEX FASPRO SC formulation arm and 37.1% (95% CI: 31.2%, 43.3%) in the IV daratumumab arm.
This study met its primary objectives to show that DARZALEX FASPRO SC formulation is non-inferior to IV daratumumab in terms of ORR and maximum trough concentration. The results are provided in Table 1. (See Table 1.)

After a median follow-up of 29.3 months, the median overall survival (OS) was 28.2 months (95% CI: 22.8, NE) in the DARZALEX FASPRO formulation arm and was 25.6 months (95% CI: 22.1, NE) in the IV daratumumab arm.
Safety and tolerability results, including in lower weight patients, were consistent with the known safety profile for DARZALEX FASPRO SC formulation and IV daratumumab.
Results from the modified-CTSQ, a patient reported outcome questionnaire that assesses patient satisfaction with their therapy, demonstrated that patients receiving DARZALEX FASPRO subcutaneous formulation had greater satisfaction with their therapy compared with patients receiving IV daratumumab.
Combination treatments in multiple myeloma: MMY2040 was an open-label trial evaluating the efficacy and safety of DARZALEX FASPRO SC formulation 1800 mg: D-VMP arm: In combination with bortezomib, melphalan, and prednisone (D-VMP) in patients with newly diagnosed multiple myeloma (MM) who are ineligible for transplant. Bortezomib was administered by subcutaneous (SC) injection at a dose of 1.3 mg/m2 body surface area twice weekly at Weeks 1, 2, 4 and 5 for the first 6-week cycle (Cycle 1; 8 doses), followed by once weekly administrations at Weeks 1, 2, 4 and 5 for eight more 6-week cycles (Cycles 2-9; 4 doses per cycle). Melphalan at 9 mg/m2, and prednisone at 60 mg/m2 were orally administered on Days 1 to 4 of the nine 6-week cycles (Cycles 1-9). DARZALEX FASPRO SC formulation was continued until disease progression or unacceptable toxicity. The median duration of follow-up for patients was 6.9 months.
The median age was 75 years and approximately 51% were ≥75 years of age. The sex of the patients was evenly distributed. Most patients were white (69%). 33% had ISS Stage I, 45% had ISS Stage II, and 22% had ISS Stage III disease at screening.
D-Rd arm: In combination with lenalidomide and dexamethasone (D-Rd) in patients with relapsed or refractory MM. Lenalidomide (25 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose dexamethasone 40 mg/week (or a reduced dose of 20 mg/week for patients >75 years or BMI <18.5). DARZALEX FASPRO subcutaneous formulation was continued until disease progression or unacceptable toxicity. The median duration of follow-up for patients was 7.1 months.
The median age was 69 years. The majority of patients were male (69%). Most patients were white (69%). 42% had ISS Stage I, 30% had ISS Stage II, and 28% had ISS Stage III disease at screening. Patients had received a median of 1 prior line of therapy, 52% of patients received prior autologous stem cell transplantation (ASCT). The majority of patients (95%) received prior PI, 59% received a prior Immunomodulatory Agent including 22% who received prior lenalidomide. 54% of patients received both a prior PI and Immunomodulatory Agents.
D-Kd arm: In combination with carfilzomib and dexamethasone (D-Kd) for patients in first relapse or refractory MM after initial treatment with a lenalidomide-containing regimen. Carfilzomib was administered by IV infusion at a dose of 20 mg/m2 on Cycle 1 Day 1. If a dose of 20 mg/m2 was tolerated, carfilzomib was administered at a dose of 70 mg/m2 as a 30-minute IV infusion, on Cycle 1 Day 8 and Day 15, and then Day 1, 8 and 15 of each cycle. This was given with low-dose dexamethasone 40 mg per week (or a reduced dose of 20 mg per week for patients ≥75 years or BMI <18.5). DARZALEX FASPRO SC formulation was continued until disease progression or unacceptable toxicity. The median duration of follow-up for patients was 9.2 months.
The median age was 61 years and 52% were male. Most patients were white (73%). 68% had ISS Stage I, 18% had ISS Stage II, and 14% had ISS Stage III disease at screening. A total of 79% of patients had received prior ASCT; 91% of patients received prior PI. All patients received 1 prior line of therapy with exposure to lenalidomide and 62% of patients were refractory to lenalidomide.
A total of 198 patients (D-VMP: 67; D-Rd: 65; D-Kd: 66) were enrolled. Efficacy results were determined by computer algorithm using IMWG response criteria. Primary endpoints ORR for D-VMP, D-Rd and D-Kd and VGPR were met (see Table 2). The minimal residual disease (MRD) negativity rate for patients in the D-Kd arm was 24%, based on all treated populations and a threshold of 10-5. (See Table 2.)

Combination treatment with pomalidomide and dexamethasone in patients with multiple myeloma: Study MMY3013 was an open-label, randomized, active-controlled Phase 3 trial that compared treatment with DARZALEX FASPRO SC formulation (1800 mg) in combination with pomalidomide and low-dose dexamethasone (D-Pd) to treatment with pomalidomide and low-dose dexamethasone (Pd) in patients with multiple myeloma who had received at least one prior therapy with lenalidomide and a protease inhibitor (PI). Pomalidomide (4 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose oral or intravenous dexamethasone 40 mg/week (or a reduced dose of 20 mg/week for patients >75 years). On DARZALEX FASPRO SC formulation administration days, 20 mg of the dexamethasone dose was given as a pre-administration medication and the remainder given the day after the administration. For patients on a reduced dexamethasone dose, the entire 20 mg dose was given as a DARZALEX FASPRO SC formulation pre-administration medication. Dose adjustments for pomalidomide and dexamethasone were applied according to manufacturer's prescribing information. Treatment was continued in both arms until disease progression or unacceptable toxicity.
A total of 304 patients were randomized: 151 to the D-Pd arm and 153 to the Pd arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median patient age was 67 years (range 35 to 90 years), 18% were ≥75 years, 53% were male, and 89% Caucasian. Patients had received a median of 2 prior lines of therapy, with 11% of patients having received one prior line of therapy. All patients received a prior treatment with a proteasome inhibitor (PI) and lenalidomide, and 56% of patients received prior stem cell transplantation (ASCT). The majority of patients were refractory to lenalidomide (80%), a PI (48%), or both an immunomodulator and a PI (42%). Efficacy was evaluated by PFS based on IMWG criteria.
With a median follow-up of 16.9 months, the primary analysis of PFS in Study MMY3013 demonstrated a statistically significant improvement in the D-Pd arm as compared to the Pd arm; the median PFS was 12.4 months in the D-Pd arm and 6.9 months in the Pd arm (HR [95% CI]: 0.63 [0.47, 0.85]; p-value = 0.0018), representing a 37% reduction in the risk of disease progression or death for patients treated with D-Pd versus Pd. Median OS was not reached for either treatment group. (See Figure 1.)

In responders, the median time to response was 1 month (range: 0.9 to 9.1 months) in the D-Pd group and 1.9 months (range: 0.9 to 17.3 months) in the Pd group. The median duration of response had not been reached in the D-Pd group (range: 1 to 34.9+ months) and was 15.9 months (range: 1+ to 24.8 months) in the Pd group.
Patients treated with D-Pd reported a reduction in pain severity as measured with the EORTC QLQ-C30 and maintained baseline health-related quality of life, symptoms, and functioning for the other EORTC QLQ-C30 and EORTC QLQ-MY20 subscales. These benefits were not observed in patients treated with Pd.
Combination treatment with bortezomib, cyclophosphamide and dexamethasone in patients with AL amyloidosis: Study AMY3001, an open-label, randomized, active-controlled Phase 3 study, compared treatment with DARZALEX FASPRO subcutaneous formulation (1800 mg) in combination with bortezomib, cyclophosphamide and dexamethasone (D-VCd) to treatment with bortezomib, cyclophosphamide and dexamethasone (VCd) alone in patients with newly diagnosed AL amyloidosis. Randomization was stratified by AL amyloidosis Cardiac Staging System, countries that typically offer autologous stem cell transplant (ASCT) for patients with AL amyloidosis, and renal function.
All patients enrolled in study AMY3001 had newly diagnosed AL amyloidosis with at least one affected organ, measurable hematologic disease, cardiac stage I-IIIA (based on European Modification of Mayo 2004 cardiac stage), and NYHA class I-IIIA. Patients with NYHA class IIIB and IV were excluded.
Bortezomib (SC; 1.3 mg/m2 body surface area), cyclophosphamide (oral or IV; 300 mg/m2 body surface area; max dose 500 mg), and dexamethasone (oral or IV; 40 mg or a reduced dose of 20 mg for patients >70 years or body mass index [BMI] <18.5 or those who have hypervolemia, poorly controlled diabetes mellitus or prior intolerance to steroid therapy) were administered weekly on Days 1, 8, 15, and 22 of repeated 28-day [4-week] cycles. On the days of DARZALEX FASPRO dosing, 20 mg of the dexamethasone dose was given as a pre-injection medication and the remainder given the day after DARZALEX FASPRO administration. Bortezomib, cyclophosphamide and dexamethasone were given for six 28-day [4-week] cycles in both treatment arms, while DARZALEX FASPRO treatment was continued until disease progression, start of subsequent therapy, or a maximum of 24 cycles (~2 years) from the first dose of study treatment. Dose adjustments for bortezomib, cyclophosphamide and dexamethasone were applied according to manufacturer's prescribing information.
A total of 388 patients were randomized: 195 to the D-VCd arm and 193 to the VCd arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The majority (79%) of patients had lambda free light chain disease. The median patient age was 64 years (range: 34 to 87); 47% were ≥65 years; 58% were male; 76% Caucasian, 17% Asian, and 3% African American; 23% had AL amyloidosis Clinical Cardiac Stage I, 40% had Stage II, 35% had Stage IIIA, and 2% had Stage IIIB. The median number of organs involved was 2 (range: 1-6) and 66% of patients had 2 or more organs involved. Vital organ involvement was: 71% cardiac, 59% renal and 8% hepatic. The major efficacy outcome measure was hematologic complete response (HemCR) rate as determined by the Independent Review Committee assessment based on International Concensus Criteria. Study AMY3001 demonstrated an improvement in HemCR in the D-VCd arm as compared to the VCd arm. Efficacy results are summarized in Table 4. (See Table 4.)

In responders, the median time to HemCR was 60 days (range: 8 to 299 days) in the D-VCd group and 85 days (range: 14 to 340 days) in the VCd group. The median time to VGPR or better was 17 days (range: 5 to 336 days) in the D-VCd group and 25 days (range: 8 to 171 days) in the VCd group. The median duration of HemCR had not been reached in either arm. (See Figure 2.)

The median follow-up for the study is 11.4 months. The median major organ deterioration progression-free survival (MOD-PFS) was not reached for patients in either arm. The median major organ deterioration event-free survival (MOD-EFS) was not reached for patients receiving D-VCd and was 8.8 months for patients receiving VCd. The hazard ratio for MOD-EFS was 0.39 (95% CI: 0.27, 0.56) and the nominal p-value was <0.0001. Overall survival (OS) data were not mature. A total of 56 deaths were observed [N=27 (13.8%) D-VCd vs. N=29 (15%) VCd group].
Patients treated with D-VCd reported clinically meaningful improvement in fatigue and Global Health Status compared with VCd at week 16 of treatment, assessed using EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-items). After 6 cycles of treatment, there were meaningful improvements in patients HRQoL (health-related quality of life) outcomes with continued daratumumab treatment. No adjustments were made for multiplicity.
Clinical experience with daratumumab intravenous formulation: Newly Diagnosed Multiple Myeloma Eligible for ASCT: Combination with bortezomib, thalidomide and dexamethasone in patients eligible for autologous stem cell transplant (ASCT): Study MMY3006, an open-label, randomized, active-controlled Phase 3 study compared induction and consolidation treatment with IV daratumumab 16 mg/kg in combination with bortezomib, thalidomide and dexamethasone (D-VTd) to treatment with bortezomib, thalidomide and dexamethasone (VTd) in patients with newly diagnosed multiple myeloma eligible for ASCT. The consolidation phase of treatment began a minimum of 30 days post-ASCT, when the patient had recovered sufficiently, and engraftment was complete.
Bortezomib was administered by subcutaneous (SC) injection or intravenous (IV) injection at a dose of 1.3 mg/m2 body surface area twice weekly for two weeks (Days 1, 4, 8, and 11) of repeated 28-day (4-week) induction treatment cycles (Cycles 1-4) and two consolidation cycles (Cycles 5 and 6) following ASCT after Cycle 4. Thalidomide was administered orally at 100 mg daily during the six bortezomib cycles. Dexamethasone (oral or intravenous) was administered at 40 mg on Days 1, 2, 8, 9, 15, 16, 22 and 23 of Cycles 1 and 2, and at 40 mg on Days 1-2 and 20 mg on subsequent dosing days (Days 8, 9, 15, 16) of Cycles 3-4. Dexamethasone 20 mg was administered on Days 1, 2, 8, 9, 15, 16 in Cycles 5 and 6. On the days of IV daratumumab infusion, the dexamethasone dose was administered intravenously as a pre-infusion medication. Dose adjustments for bortezomib, thalidomide and dexamethasone were applied according to manufacturer's prescribing information.
A total of 1085 patients were randomized: 543 to the D-VTd arm and 542 to the VTd arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median age was 58 (range: 22 to 65 years). The majority were male (59%), 48% had an ECOG performance score of 0, 42% had an ECOG performance score of 1 and 10% had an ECOG performance score of 2. Forty percent had ISS Stage I, 45% had ISS Stage II and 15% had ISS Stage III disease.
Efficacy was evaluated by the stringent Complete Response (sCR) rate at Day 100 post-transplant. (See Table 5.)

With a median follow-up of 18.8 months, the primary analysis of PFS in study MMY3006 demonstrated an improvement in PFS in the D-VTd arm as compared to the VTd arm; the median PFS had not been reached in either arm. Treatment with D-VTd resulted in a reduction in the risk of progression or death by 53% compared to VTd alone (HR=0.47; 95% CI: 0.33, 0.67; p<0.0001). Results of an updated PFS analysis after a median follow-up of 44.5 months continued to show an improvement in PFS for patients in the D-VTd arm compared with the VTd arm. Median PFS was not reached in the D-VTd arm and was 51.5 months in the VTd arm (HR=0.58; 95% CI: 0.47, 0.71; p<0.0001), representing a 42% reduction in the risk of disease progression or death in patients treated with D-VTd.
Newly Diagnosed Multiple Myeloma Ineligible for ASCT: Combination treatment with lenalidomide and dexamethasone in patients ineligible for autologous stem cell transplant: Study MMY3008 an open-label, randomized, active-controlled Phase 3 study, compared treatment with IV daratumumab 16 mg/kg in combination with lenalidomide and low-dose dexamethasone (D-Rd) to treatment with lenalidomide and low-dose dexamethasone (Rd) in patients with newly diagnosed multiple myeloma. Lenalidomide (25 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose oral or intravenous dexamethasone 40 mg/week (or a reduced dose of 20 mg/week for patients >75 years or body mass index [BMI] <18.5). On IV daratumumab infusion days, the dexamethasone dose was given as a pre-infusion medication. Dose adjustments for lenalidomide and dexamethasone were applied according to manufacturer's prescribing information. Treatment was continued in both arms until disease progression or unacceptable toxicity.
A total of 737 patients were randomized: 368 to the D-Rd arm and 369 to the Rd arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median age was 73 (range: 45-90) years, with 44% of the patients ≥75 years of age. The majority were white (92%), male (52%), 34% had an Eastern Cooperative Oncology Group (ECOG) performance score of 0, 50% had an ECOG performance score of 1 and 17% had an ECOG performance score of ≥2. Twenty-seven percent had International Staging System (ISS) Stage I, 43% had ISS Stage II and 29% had ISS Stage III disease. Efficacy was evaluated by progression free survival (PFS) based on International Myeloma Working Group (IMWG) criteria and overall survival (OS).
With a median follow-up of 28 months, the primary analysis of PFS in study MMY3008 demonstrated an improvement in the D-Rd arm as compared to the Rd arm; the median PFS had not been reached in the D-Rd arm and was 31.9 months in the Rd arm (hazard ratio [HR]=0.56; 95% CI: 0.43, 0.73; p<0.0001), representing 44% reduction in the risk of disease progression or death in patients treated with D-Rd. Results of an updated PFS analysis after a median follow-up of 64 months continued to show an improvement in PFS for patients in the D-Rd arm compared with the Rd arm. Median PFS was 61.9 months in the D-Rd arm and 34.4 months in the Rd arm (HR=0.55; 95% CI: 0.45, 0.67; p<0.0001), representing a 45% reduction in the risk of disease progression or death in patients treated with D-Rd.
After a median follow-up of 56 months, D-Rd has shown an OS advantage over the Rd arm (HR=0.68; 95% CI: 0.53, 0.86; p=0.0013), representing a 32% reduction in the risk of death in patients treated in the D-Rd arm. Median OS was not reached for either arm. The 60-month survival rate was 66% (95% CI: 61, 71) in the D-Rd arm and was 53% (95% CI: 47, 59) in the Rd arm.
In responders, the median time to response was 1.05 months (range: 0.2 to 12.1 months) in the D-Rd group and 1.05 months (range: 0.3 to 15.3 months) in the Rd group. The median duration of response had not been reached in the D-Rd group and was 34.7 months (95% CI: 30.8, not estimable) in the Rd group.
Additional efficacy results from Study MMY3008 are presented in Table 6 as follows.
Combination treatment with bortezomib, melphalan and prednisone (VMP) in patients ineligible for autologous stem cell transplant: Study MMY3007, an open-label, randomized, active-controlled Phase 3 study, compared treatment with IV daratumumab 16 mg/kg in combination with bortezomib, melphalan and prednisone (D-VMP), to treatment with VMP in patients with newly diagnosed multiple myeloma. Bortezomib was administered by subcutaneous (SC) injection at a dose of 1.3 mg/m2 body surface area twice weekly at Weeks 1, 2, 4 and 5 for the first 6-week cycle (Cycle 1; 8 doses), followed by once weekly administrations at Weeks 1, 2, 4 and 5 for eight more 6-week cycles (Cycles 2-9; 4 doses per cycle). Melphalan at 9 mg/m2 and prednisone at 60 mg/m2 were orally administered on Days 1 to 4 of the nine 6-week cycles (Cycles 1-9). IV daratumumab treatment was continued until disease progression or unacceptable toxicity.
A total of 706 patients were randomized: 350 to the D-VMP arm and 356 to the VMP arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median age was 71 (range: 40-93) years, with 30% of the patients ≥75 years of age. The majority were white (85%), female (54%), 25% had an ECOG performance score of 0, 50% had an ECOG performance score of 1 and 25% had an ECOG performance score of 2. Patients had IgG/IgA/Light chain myeloma in 64%/22%/10% of instances, 19% had ISS Stage I, 42% had ISS Stage II and 38% had ISS Stage III disease. Efficacy was evaluated by PFS based on IMWG criteria and overall survival (OS).
With a median follow-up of 16.5 months, the primary analysis of PFS in study MMY3007 demonstrated an improvement in the D-VMP arm as compared to the VMP arm; the median PFS had not been reached in the D-VMP arm and was 18.1 months in the VMP arm (HR=0.5; 95% CI: 0.38, 0.65; p<0.0001), representing 50% reduction in the risk of disease progression or death in patients treated with D-VMP. Results of an updated PFS analysis after a median follow-up of 40 months continued to show an improvement in PFS for patients in the D-VMP arm compared with the VMP arm. Median PFS was 36.4 months in the D-VMP arm and 19.3 months in the VMP arm (HR=0.42; 95% CI: 0.34, 0.51; p<0.0001), representing a 58% reduction in the risk of disease progression or death in patients treated with D-VMP.
After a median follow-up of 40 months, D-VMP has shown an overall survival (OS) advantage over the VMP arm (HR=0.60; 95% CI: 0.46, 0.80; p=0.0003), representing a 40% reduction in the risk of death in patients treated in the D-VMP arm. Median OS was not reached for either arm.
In responders, the median time to response was 0.79 months (range: 0.4 to 15.5 months) in the D-VMP group and 0.82 months (range: 0.7 to 12.6 months) in the VMP group. The median duration of response had not been reached in the D-VMP group and was 21.3 months (range: 18.4, not estimable) in the VMP group.

Relapsed/Refractory Multiple Myeloma: Combination treatment with lenalidomide and dexamethasone: Study MMY3003, an open-label, randomized, active-controlled Phase 3 trial, compared treatment with IV daratumumab 16 mg/kg in combination with lenalidomide and low-dose dexamethasone (D-Rd) to treatment with lenalidomide and low-dose dexamethasone (Rd) in patients with multiple myeloma who had received at least one prior therapy. Lenalidomide (25 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose oral or intravenous dexamethasone 40 mg/week (or a reduced dose of 20 mg/week for patients >75 years or BMI <18.5). On IV daratumumab infusion days, 20 mg of the dexamethasone dose was given as a pre-infusion medication and the remainder given the day after the infusion. For patients on a reduced dexamethasone dose, the entire 20 mg dose was given as an IV daratumumab pre-infusion medication. Dose adjustments for lenalidomide and dexamethasone were applied according to manufacturer's prescribing information. Treatment was continued in both arms until disease progression or unacceptable toxicity.
A total of 569 patients were randomized; 286 to the D-Rd arm and 283 to the Rd arm. The baseline demographic and disease characteristics were similar between the IV daratumumab and the control arm. The median patient age was 65 years (range 34 to 89 years), 11% were ≥75 years, 59% were male; 69% Caucasian, 18% Asian, and 3% African American. Patients had received a median of 1 prior line of therapy. Sixty-three percent (63%) of patients had received prior autologous stem cell transplantation (ASCT). The majority of patients (86%) received a prior proteasome inhibitor (PI), 55% of patients had received a prior immunomodulatory agent (IMiD), including 18% of patients who had received prior lenalidomide, and 44% of patients had received both a prior PI and IMiD. At baseline, 27% of patients were refractory to the last line of treatment. Eighteen percent (18%) of patients were refractory to a PI only, and 21% were refractory to bortezomib. Efficacy was evaluated by PFS based on IMWG criteria and overall survival (OS).
With a median follow-up of 13.5 months, the primary analysis of PFS in study MMY3003 demonstrated an improvement in the D-Rd arm as compared to the Rd arm; the median PFS had not been reached in the D-Rd arm and was 18.4 months in the Rd arm (HR=0.37; 95% CI: 0.27, 0.52; p<0.0001) representing 63% reduction in the risk of disease progression or death in patients treated with D-Rd. Results of an updated PFS analysis after a median follow-up of 55 months continued to show an improvement in PFS for patients in the D-Rd arm compared with the Rd arm. Median PFS was 45.0 months in the D-Rd arm and 17.5 months in the Rd arm (HR=0.44; 95% CI: 0.35, 0.54; p<0.0001), representing a 56% reduction in the risk of disease progression or death in patients treated with D-Rd.
After a median follow-up of 80 months, D-Rd has shown an OS advantage over the Rd arm (HR=0.73; 95% CI: 0.58, 0.91; p=0.0044), representing a 27% reduction in the risk of death in patients treated in the D-Rd arm. The median OS was 67.6 months in the D-Rd arm and 51.8 months in the Rd arm. The 78-month survival rate was 47% (95% CI: 41, 52) in the DRd arm and was 35% (95% CI: 30, 41) in the Rd arm.
Additional efficacy results from Study MMY3003 are presented in Table 6 as follows.
Combination treatment with bortezomib and dexamethasone: Study MMY3004, an open-label, randomized, active-controlled Phase 3 trial, compared treatment with IV daratumumab 16 mg/kg in combination with bortezomib and dexamethasone (D-Vd), to treatment with bortezomib and dexamethasone (Vd) in patients with multiple myeloma who had received at least one prior therapy. Bortezomib was administered by SC injection or IV injection at a dose of 1.3 mg/m2 body surface area twice weekly for two weeks (Days 1, 4, 8, and 11) of repeated 21 day (3-week) treatment cycles, for a total of 8 cycles. Dexamethasone was administered orally at a dose of 20 mg on Days 1, 2, 4, 5, 8, 9, 11, and 12 of the 8 bortezomib cycles (80 mg/week for two out of three weeks of each of the bortezomib cycle) or a reduced dose of 20 mg/week for patients >75 years, BMI <18.5, poorly controlled diabetes mellitus or prior intolerance to steroid therapy. On the days of IV daratumumab infusion, 20 mg of the dexamethasone dose was administered as a pre-infusion medication. For patients on a reduced dexamethasone dose, the entire 20 mg dose was given as an IV daratumumab pre-infusion medication. Bortezomib and dexamethasone were given for 8 three-week cycles in both treatment arms; whereas IV daratumumab was given until treatment progression. However, dexamethasone 20 mg was continued as an IV daratumumab pre-infusion medication in the D-Vd arm. Dose adjustments for bortezomib and dexamethasone were applied according to manufacturer's prescribing information.
A total of 498 patients were randomized; 251 to the D-Vd arm and 247 to the Vd arm. The baseline demographic and disease characteristics were similar between the IV daratumumab and the control arm. The median patient age was 64 years (range 30 to 88 years); 12% were ≥75 years, 57% were male; 87% Caucasian, 5% Asian and 4% African American. Patients had received a median of 2 prior lines of therapy and 61% of patients had received prior autologous stem cell transplantation (ASCT). Sixty-nine percent (69%) of patients had received a prior PI (66% received bortezomib) and 76% of patients received an IMiD (42% received lenalidomide). At baseline, 32% of patients were refractory to the last line of treatment and the proportions of patients refractory to any specific prior therapy were well balanced between the treatment groups. Thirty-three percent (33%) of patients were refractory to an IMiD only, and 28% were refractory to lenalidomide. Efficacy was evaluated by PFS based on IMWG criteria and overall survival (OS).
With a median follow-up of 7.4 months, the primary analysis of PFS in study MMY3004 demonstrated an improvement in the D-Vd arm as compared to the Vd arm; the median PFS had not been reached in the D-Vd arm and was 7.2 months in the Vd arm (HR [95% CI]: 0.39 [0.28, 0.53]; p-value <0.0001), representing a 61% reduction in the risk of disease progression or death for patients treated with D-Vd versus Vd. Results of an updated PFS analysis after a median follow-up of 50 months continued to show an improvement in PFS for patients in the D-Vd arm compared with the Vd arm. Median PFS was 16.7 months in the D-Vd arm and 7.1 months in the Vd arm (HR [95% CI]: 0.31 [0.24, 0.39]; p-value <0.0001), representing a 69% reduction in the risk of disease progression or death in patients treated with D-Vd versus Vd.
After a median follow-up of 73 months, D-Vd has shown an OS advantage over the Vd arm (HR=0.74: 95% CI: 0.59, 0.92; p=0.0075), representing a 26% reduction in the risk of death in patients treated in the D-Vd arm. The median OS was 49.6 months in the D-Vd arm and 38.5 months in the Vd arm. The 72-month survival rate was 39% (95% CI: 33, 45) in the D-Vd arm and was 25% (95% CI: 20, 31) in the Vd arm.
Additional efficacy results from Study MMY3004 are presented in Table 6 as follows. (See Table 6.)

Combination treatment with pomalidomide and dexamethasone: Study MMY1001 was an open-label trial in which 103 patients with multiple myeloma who had received a prior PI and an IMiD, received IV daratumumab 16 mg/kg in combination with pomalidomide and low-dose dexamethasone until disease progression. Pomalidomide (4 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose oral or intravenous dexamethasone at 40 mg/week (reduced dose of 20 mg/week for patients >75 years or BMI <18.5). On IV daratumumab infusion days, 20 mg of the dexamethasone dose was given as a pre-infusion medication and the remainder given the day after the infusion. For patients on a reduced dexamethasone dose, the entire 20 mg dose was given as an IV daratumumab pre-infusion medication.
The median patient age was 64 years (range: 35 to 86 years) with 8% of patients ≥75 years of age. Patients in the study had received a median of 4 prior lines of therapy. Seventy-four percent (74%) of patients had received prior ASCT. Ninety eight percent (98%) of patients received prior bortezomib treatment, and 33% of patients received prior carfilzomib. All patients received prior lenalidomide treatment, with 98% of patients previously treated with the combination of bortezomib and lenalidomide. Eighty nine percent (89%) of patients were refractory to lenalidomide and 71% refractory to bortezomib; 64% of patients were refractory to bortezomib and lenalidomide.
Overall response rate was 59% (95% CI: 49.1%, 68.8%); VGPR or better was achieved in 42% of patients, CR or better was achieved in 14% of patients and stringent CR was achieved in 8% of patients. The Clinical Benefit Rate (ORR+ MR [Minimal response]) was 62% (95% CI: 52.0, 71.5). The median time to response was 1 month (range: 0.9 to 2.8 months). The median duration of response was 13.6 months (95% CI: 10.0, not estimable). After a median duration of follow-up of 9.8 months, the median OS was not reached. The 12-month survival rate was 72%.
Combination treatment with twice-weekly (20/56 mg/m2) carfilzomib and dexamethasone: Study 20160275, an open-label, randomized, active-controlled Phase 3 trial, compared treatment with DARZALEX 16 mg/kg in combination with carfilzomib and dexamethasone (DKd) to treatment with carfilzomib and dexamethasone (Kd) in patients with multiple myeloma who had received at least one to three prior lines of therapy.
Carfilzomib was administered as IV infusion twice weekly on Days 1, 2, 8, 9, 15, and 16 of repeated 28-day [4-week] treatment cycles. Carfilzomib dose was 20 mg/m2 on Cycle 1 Days 1 and 2 and 56 mg/m2 beginning on Cycle 1 Day 8 and thereafter.
Dexamethasone was administered orally or by IV infusion at a dose of 40 mg weekly. Dexamethasone was administered as an IV infusion on carfilzomib and/or DARZALEX IV infusion days. On the days of DARZALEX and/or carfilzomib infusion, 20 mg of the dexamethasone dose was administered via IV as a pre-infusion medication. The remaining 20 mg of dexamethasone was administered via IV on successive day of carfilzomib and/or DARZALEX infusions. For patients >75 years on a reduced dexamethasone dose of 20 mg, the entire 20 mg dose was given as a DARZALEX pre-infusion medication. Dose adjustments for carfilzomib and dexamethasone were applied according to manufacturer's prescribing information. Treatment was continued in both arms until disease progression or unacceptable toxicity.
A total of 466 patients were randomized; 312 to the DKd arm and 154 to the Kd arm. The baseline demographic and disease characteristics were similar between the DARZALEX and the control arm. The median patient age was 64 years (range 29 to 84 years), 9% were ≥75 years, 58% were male; 79% Caucasian, 14% Asian, and 2% African American. Patients had received a median of 2 prior lines of therapy and 58% of patients had received prior autologous stem cell transplantation (ASCT). The majority of patients (92%) received a prior PI and of those 34% were refractory to PI including regimen. Fourty-two percent (42%) of patients had received prior lenalidomide and of those, 33% were refractory to a lenalidomide containing regimen.
Efficacy was evaluated by PFS based on IMWG criteria. Study 20160275 demonstrated an improvement in PFS in the DKd arm as compared to the Kd arm; the median PFS had not been reached in the DKd arm and was 15.8 months in the Kd arm (hazard ratio [HR]=0.630; 95% CI: 0.464, 0.854; p=0.0014), representing 37% reduction in the risk of disease progression or death for patients treated with DKd versus Kd. PFS improvement observed in the ITT population was also observed in lenalidomide refractory patients. (See Figure 3.)

After a median follow-up of 17.1 months, 95 deaths were observed [N=59 (19%) in the DKd group and N=36 (23%) in the Kd group]. Overall survival (OS) data were not mature, however, there was a trend toward longer OS in the DKd arm compared with the Kd arm (HR=0.745; 95% CI: 0.491, 1.131; p=0.0836).
Additional efficacy results from Study 20160275 are presented in the table as follows. (See Table 7.)

In responders, the median time to response was 1 month (range: 1 to 14 months) in the DKd group and 1 month (range: 1 to 10 months) in the Kd group. The median duration of response had not been reached in the DKd group and was 16.6 months (95% CI: 13.9, not estimable) in the Kd group.
Combination treatment with once-weekly (20/70 mg/m2) carfilzomib and dexamethasone: Study MMY1001 was an open-label trial in which 85 patients with multiple myeloma who had received at least one prior therapy, received 16 mg/kg DARZALEX in combination with carfilzomib and low-dose dexamethasone until disease progression. Carfilzomib was administered as IV infusion once weekly at a dose of 20 mg/m2 on Cycle 1 Day 1 and escalated to dose of 70 mg/m2 on Cycle 1 Days 8 and 15, and Days 1, 8, and 15 of subsequent cycles. Dexamethasone was given at 40 mg (subjects ≤75 years) or 20 mg (subjects >75 years) per week. For first DARZALEX split-dose, dexamethasone was administered on Day 1 and Day 2 before the DARZALEX infusions. During other DARZALEX infusion weeks, dexamethasone was administered on infusion days at a dose of 20 mg before the DARZALEX infusion and 20 mg the day after the DARZALEX infusion.
The median patient age was 66 years (range: 38 to 85 years) with 9% of patients ≥75 years of age. Patients in the study had received a median of 2 prior lines of therapy. Seventy three percent (73%) of patients had received prior ASCT. All patients received prior bortezomib, and 95% of patients received prior lenalidomide. Sixty percent (60%) of patients were refractory to lenalidomide and 29% of patients were refractory to both a PI an IMiD.
Efficacy results were based on overall response rate using IMWG criteria (see Table 8).

The median duration of response was 28 months (95% CI: 20.5, not estimable). The median PFS was 26 months (95% CI: 4.8, NE), after a median follow-up of 24 months. Median overall survival was not reached. The 24-month survival rate was 71%.
Monotherapy: The clinical efficacy and safety of DARZALEX monotherapy for the treatment of patients with relapsed and refractory multiple myeloma whose prior therapy included a proteasome inhibitor and an immunomodulatory agent, was demonstrated in two open-label studies.
In Study MMY2002, 106 patients with relapsed and refractory multiple myeloma received 16 mg/kg DARZALEX until disease progression. The median patient age was 63.5 years (range, 31 to 84 years), 49% were male and 79% were Caucasian. Patients had received a median of 5 prior lines of therapy. Eighty percent of patients had received prior autologous stem cell transplantation (ASCT). Prior therapies included bortezomib (99%), lenalidomide (99%), pomalidomide (63%) and carfilzomib (50%). At baseline, 97% of patients were refractory to the last line of treatment, 95% were refractory to both, a PI and IMiD, 77% were refractory to alkylating agents, 63% were refractory to pomalidomide and 48% of patients were refractory to carfilzomib.
Efficacy results based on Independent Review Committee (IRC) assessment are presented in the table as follows. (See Table 9.)

Overall response rate (ORR) in MMY2002 was similar regardless of type of prior anti-myeloma therapy. With a median duration of follow-up of 9 months, median OS was not reached. The 12-month OS rate was 65% (95% CI: 51.2, 75.5).
In Study GEN501, 42 patients with relapsed and refractory multiple myeloma received 16 mg/kg DARZALEX until disease progression. The median patient age was 64 years (range, 44 to 76 years), 64% were male and 76% were Caucasian. Patients in the study had received a median of 4 prior lines of therapy. Seventy-four percent of patients had received prior ASCT. Prior therapies included bortezomib (100%), lenalidomide (95%), pomalidomide (36%) and carfilzomib (19%). At baseline, 76% of patients were refractory to the last line of treatment, 64% were refractory to both a PI and IMiD, 60% were refractory to alkylating agents, 36% were refractory to pomalidomide and 17% were refractory to carfilzomib.
Treatment with daratumumab at 16 mg/kg led to a 36% ORR with 5% CR and 5% VGPR. The median time to response was 1 (range: 0.5 to 3.2) month. The median duration of response was not reached (95% CI: 5.6 months, not estimable). With a median duration of follow-up of 10 months, median OS was not reached. The 12-month OS rate was 77% (95% CI: 58.0, 88.2).
Pharmacokinetics: Daratumumab exposure in a monotherapy study (MMY3012) in patients with multiple myeloma following the recommended 1800 mg administration of DARZALEX FASPRO SC formulation (weekly for 8 weeks, biweekly for 16 weeks, monthly thereafter) as compared to 16 mg/kg IV daratumumab for the same dosing schedule, showed non-inferiority for the co-primary endpoint of maximum Ctrough (Cycle 3 Day 1 pre-dose), with mean ± SD of 593±306 μg/mL compared to 522±226 μg/mL for IV daratumumab, with a geometric mean ratio of 107.93% (90% CI: 95.74-121.67).
Daratumumab exhibits both concentration and time-dependent pharmacokinetics with first order absorption and parallel linear and nonlinear (saturable) elimination that is characteristic of target-mediated clearance. Following the recommended dose of 1800 mg DARZALEX FASPRO SC formulation as monotherapy, peak concentrations (Cmax) increased 4.8-fold and total exposure (AUC0-7 days) increased 5.4-fold from first dose to last weekly dose (8th dose). Highest trough concentrations for DARZALEX FASPRO SC formulation are typically observed at the end of the weekly dosing regimens for both monotherapy and combination therapy.
In patients with multiple myeloma, the simulated trough concentrations following 6 weekly doses of 1800 mg DARZALEX FASPRO for combination therapy were similar to 1800 mg DARZALEX FASPRO monotherapy.
In patients with multiple myeloma, daratumumab exposure in a combination study with pomalidomide and dexamethasone (MMY3013) was similar to that in monotherapy, with the maximum Ctrough (Cycle 3 Day 1 pre-dose) mean ± SD of 537±277 μg/mL following the recommended 1800 mg administration of DARZALEX FASPRO SC formulation (weekly for 8 weeks, biweekly for 16 weeks, monthly thereafter).
In a combination study, AMY3001, in patients with AL amyloidosis, the maximum Ctrough (Cycle 3 Day 1 pre-dose) was similar to that in multiple myeloma with mean ± SD of 597±232 μg/mL following the recommended 1800 mg administration of DARZALEX FASPRO SC formulation (weekly for 8 weeks, biweekly for 16 weeks, monthly thereafter).
Absorption and Distribution: At the recommended dose of 1800 mg in multiple myeloma patients, the absolute bioavailability of DARZALEX FASPRO SC formulation is 69%, with an absorption rate of 0.012 hour-1, with peak concentrations occurring at 70 to 72 h (Tmax). At the recommended dose of 1800 mg in AL amyloidosis patients, the absolute bioavailability was not estimated, the absorption rate constant was 0.77 day-1 (8.31% CV) and peak concentrations occurred at 3 days.
In multiple myeloma patients, the modeled mean estimate of the volume of distribution for the central compartment (V1) is 5.25 L (36.9% CV) and peripheral compartment (V2) was 3.78 L in daratumumab monotherapy, and the modeled mean estimate of the volume of distribution for V1 is 4.36 L (28% CV) and V2 was 2.80 L when daratumumab was administered in combination with pomalidomide and dexamethasone. In AL amyloidosis patients, the model estimated apparent volume of distribution after SC administration is 10.8 L (3.1% CV). These results suggest that daratumumab is primarily localized to the vascular system with limited extravascular tissue distribution.
Metabolism and Elimination: Daratumumab is cleared by parallel linear and nonlinear saturable target-mediated clearances. In multiple myeloma patients, the population PK model estimated mean clearance value of daratumumab is 4.96 mL/h (58.7% CV) in daratumumab monotherapy and 4.32 mL/h (43.5% CV) when daratumumab was administered in combination with pomalidomide and dexamethasone. In AL amyloidosis patients, the apparent clearance after SC administration is 210 mL/day (4.1% CV).
In multiple myeloma patients, the model-based geometric mean post hoc estimate for half-life associated with linear elimination is 20.4 days (22.4% CV) in daratumumab monotherapy and 19.7 days (15.3% CV) when daratumumab was administered in combination with pomalidomide and dexamethasone. In AL amyloidosis patients, the model-based geometric mean post hoc estimate for half-life associated with linear elimination is 27.5 days (74.0% CV). For the monotherapy and combination regimens, the steady state is achieved at approximately 5 months into every 4 weeks dosage at the recommended dose and schedule (1800 mg; once weekly for 8 weeks, every 2 weeks for 16 weeks, and then every 4 weeks thereafter).
A population PK analysis, using data from DARZALEX FASPRO SC formulation monotherapy and combination therapy in multiple myeloma patients, was conducted with data from 487 patients who received DARZALEX FASPRO SC formulation and 255 patients who received IV daratumumab. The predicted PK exposures are summarized in Table 10. (See Table 10.)

A population PK analysis, using data from DARZALEX FASPRO SC formulation combination therapy in AL amyloidosis patients, was conducted with data from 211 patients. At the recommended dose of 1,800 mg, predicted daratumumab concentrations were slightly higher, but generally within the same range, in comparison with multiple myeloma patients. (See Table 11.)

Special populations: Age and gender: Based on population PK analyses in patients (33-92 years) receiving monotherapy or various combination therapies, age had no statistically significant effect on the PK of daratumumab. No individualization is necessary for patients on the basis of age.
Gender had a statistically significant effect on PK parameters in patients with multiple myeloma but not in patients with AL amyloidosis. Slightly higher exposure in females were observed than males, but the difference in exposure is not considered clinically meaningful. No individualization is necessary for patients on the basis of gender.
Renal impairment: No formal studies of DARZALEX FASPRO SC formulation in patients with renal impairment have been conducted. Population PK analyses were performed based on pre-existing renal function data in patients with multiple myeloma receiving DARZALEX FASPRO monotherapy or various combination therapies in patients with multiple myeloma or AL amyloidosis and no clinically important differences in exposure to daratumumab were observed between patients with renal impairment and those with normal renal function.
Hepatic impairment: No formal studies of DARZALEX FASPRO SC formulation in patients with hepatic impairment have been conducted. Population PK analyses were performed in patients with multiple myeloma receiving DARZALEX FASPRO SC formulation monotherapy or various combination therapies in patients with multiple myeloma or in AL amyloidosis. No clinically important differences in the exposure to daratumumab were observed between patients with normal hepatic function and mild hepatic impairment. There were very few patients with moderate and severe hepatic impairment to make meaningful conclusions for these populations.
Race: Based on the population PK analyses in patients receiving either DARZALEX FASPRO SC formulation monotherapy or various combination therapies, the daratumumab exposure was similar across races.
Body Weight: The flat-dose administration of DARZALEX FASPRO subcutaneous formulation 1800 mg as monotherapy achieved adequate exposure for all body-weight subgroups. In patients with multiple myeloma, the mean cycle 3 day 1 Ctrough in the lower body-weight subgroup (≤65 kg) was 60% higher and in the higher body weight (>85 kg) subgroup, 12% lower than the intravenous daratumumab subgroup. In some patients with body weight >120 kg, lower exposure was observed which may result in reduced efficacy. However, this observation is based on limited number of patients.
In patients with AL amyloidosis, no meaningful differences were observed in Ctrough across body weight.
Non-clinical Information: Carcinogenicity and Mutagenicity: No animal studies have been performed to establish the carcinogenic potential of daratumumab. Routine genotoxicity and carcinogenicity studies are generally not applicable to biologic pharmaceuticals as large proteins cannot diffuse into cells and cannot interact with DNA or chromosomal material.
Reproductive Toxicology: No animal studies have been performed to evaluate the potential effects of daratumumab on reproduction or development.
No systemic exposure of hyaluronidase was detected in monkeys given 22,000 U/kg subcutaneously (12 times higher than the human dose) and there were no effects on embryo-fetal development in pregnant mice given 330,000 U/kg hyaluronidase subcutaneously daily during organogenesis, which is 45 times higher than the human dose.
There were no effects on pre- and post-natal development through sexual maturity in offspring of mice treated daily from implantation through lactation with 990,000 U/kg hyaluronidase subcutaneously, which is 134 times higher than the human doses.
Fertility: No animal studies have been performed to determine potential effects on fertility in males or females.

Dosage/Direction for Use
DARZALEX FASPRO is for subcutaneous use only. DARZALEX FASPRO has different dosage and administration instructions than intravenous daratumumab. Do not administer intravenously.
Pre- and post-infusion medications should be administered (see Recommended concomitant medications as follows).
For patients currently receiving daratumumab intravenous formulation, DARZALEX FASPRO subcutaneous formulation may be used as an alternative to the intravenous daratumumab formulation starting at the next scheduled dose.
DARZALEX FASPRO should be administered by a healthcare professional, and the first dose should be administered in an environment where resuscitation facilities are available.
It is important to check the vial labels to ensure that the appropriate formulation (intravenous or subcutaneous formulation) and dose is being given to the patient as prescribed.

Missed dose(s): If a planned dose of DARZALEX FASPRO is missed, administer the dose as soon as possible and adjust the dosing schedule accordingly, maintaining the treatment interval.
Dose modifications: No dose reductions of DARZALEX FASPRO are recommended. Dose delay may be required to allow recovery of blood cell counts in the event of hematological toxicity (see Precautions). For information concerning medicinal products given in combination with DARZALEX FASPRO, see manufacturer's prescribing information.
DARZALEX FASPRO and management of infusion-related reactions: In clinical trials, no modification to rate or dose of DARZALEX FASPRO was required to manage infusion-related reactions.
Recommended concomitant medications: Pre-injection medication: Pre-injection medications (oral or intravenous) should be administered to reduce the risk of infusion-related reactions (IRRs) to all patients 1-3 hours prior to every administration of DARZALEX FASPRO subcutaneous injection as follows: Corticosteroid (long-acting or intermediate-acting): Monotherapy: Methylprednisolone 100 mg, or equivalent. Following the second injection, the dose of corticosteroid may be reduced to methylprednisolone 60 mg.
Combination therapy: Administer 20 mg dexamethasone (or equivalent) prior to every DARZALEX FASPRO injection. When dexamethasone is the background-regimen-specific corticosteroid, the dexamethasone treatment dose will instead serve as pre-medication on DARZALEX FASPRO administration days (see Pharmacology: Pharmacodynamics: Clinical Studies under Actions).
Additional background-regimen-specific corticosteroids (e.g. prednisone) should not be taken on DARZALEX FASPRO administration days when patients have received dexamethasone (or equivalent) as a pre-medication.
Antipyretics (paracetamol/acetaminophen 650 to 1000 mg).
Antihistamine (diphenhydramine 25 to 50 mg or equivalent).
Post-injection medication: Administer post-injection medication to reduce the risk of delayed IRRs as follows: Monotherapy: Administer oral corticosteroid (20 mg methylprednisolone or equivalent dose of an intermediate-acting or long-acting corticosteroid in accordance with local standards) on each of the 2 days following all DARZALEX FASPRO injections (beginning the day after the injection).
Combination therapy: Consider administering low-dose oral methylprednisolone (≤20 mg) or equivalent the day after the DARZALEX FASPRO injection.
However, if a background regimen-specific corticosteroid (e.g. dexamethasone, prednisone) is administered the day after the DARZALEX FASPRO injection, additional post-injection medications may not be needed (see Pharmacology: Pharmacodynamics: Clinical Studies under Actions).
If the patient experiences no major IRRs after the first three injections, post-injection corticosteroids (excluding any background regimen corticosteroids) may be discontinued.
Additionally, for patients with a history of chronic obstructive pulmonary disease, consider the use of post-injection medications including short and long-acting bronchodilators, and inhaled corticosteroids. Following the first four injections, if the patient experiences no major IRRs, these inhaled post-injection medications may be discontinued at the discretion of the physician.
Prophylaxis for herpes zoster virus reactivation: Anti-viral prophylaxis should be considered for the prevention of herpes zoster virus reactivation.
Special populations: Pediatrics (17 years of age and younger): The safety and efficacy of DARZALEX FASPRO have not been established in pediatric patients.
Elderly (65 years of age and older): No dose adjustments are considered necessary in elderly patients (see Pharmacology: Pharmacokinetics under Actions, Adverse Reactions).
Renal impairment: No formal studies of daratumumab in patients with renal impairment have been conducted. Based on population pharmacokinetic (PK) analyses, no dosage adjustment is necessary for patients with renal impairment (see Pharmacology: Pharmacokinetics under Actions).
Hepatic impairment: No formal studies of daratumumab in patients with hepatic impairment have been conducted. Changes in hepatic function are unlikely to have any effect on the elimination of daratumumab since IgG1 molecules such as daratumumab are not metabolized through hepatic pathways. No dosage adjustments are necessary for patients with hepatic impairment (see Pharmacology: Pharmacokinetics under Actions).
Body weight (>120 kg): Limited number of patients with body weight >120 kg have been studied using flat-dose (1800 mg) DARZALEX FASPRO solution for subcutaneous injection and efficacy in these patients has not been established. No dose adjustment based on body weight can currently be recommended.
Cardiac disease: The safety and efficacy of DARZALEX FASPRO have not been established in AL amyloidosis patients with advanced cardiac disease (Mayo Stage IIIB or NYHA Class IIIB or IV).
Administration: DARZALEX FASPRO should be administered by a healthcare professional.
To prevent medication errors, it is important to check the vial labels to ensure that the drug being prepared and administered is DARZALEX FASPRO for subcutaneous injection and not intravenous daratumumab. DARZALEX FASPRO subcutaneous (SC) formulation is not intended for intravenous administration and should be administered via a subcutaneous injection only.
DARZALEX FASPRO is for single use only and is ready to use.
DARZALEX FASPRO is compatible with polypropylene or polyethylene syringe material; polypropylene, polyethylene, or polyvinyl chloride (PVC) subcutaneous infusion sets; and stainless steel transfer and injection needles.
DARZALEX FASPRO should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if opaque particles, discoloration or other foreign particles are present.
Unopened vial: Remove the DARZALEX FASPRO vial from refrigerated storage [2°C-8°C (36°F-46°F)] and equilibrate to ambient temperature [15°C-30°C (59°F-86°F)]. The unpunctured vial may be stored at ambient temperature and ambient light for a maximum of 24 hours. Keep out of direct sunlight. Do not shake. Once the product has been taken out of the refrigerator, it must not be returned to the refrigerator.
Prepare the dosing syringe in controlled and validated aseptic conditions.
To avoid needle clogging, attach the hypodermic injection needle or subcutaneous infusion set to the syringe immediately prior to injection.
Storage of prepared syringe: If the syringe containing DARZALEX FASPRO is not used immediately, store the DARZALEX FASPRO solution for up to 24 hours refrigerated (2-8°C) followed by up to 7 hours at 15°C-30°C (59°F-86°F) and ambient light. Discard if stored more than 24 hours of being refrigerated (2-8°C) or more than 7 hours of being at 15°C-30°C (59°F-86°F), if not used. If stored in the refrigerator, allow the solution to come to ambient temperature before administration.
Method of Administration: Inject 15 mL DARZALEX FASPRO into the subcutaneous tissue of the abdomen approximately 3 inches [7.5 cm] to the right or left of the navel over approximately 3-5 minutes. Do not inject DARZALEX FASPRO at other sites of the body as no data are available.
Injection sites should be rotated for successive injections.
DARZALEX FASPRO should never be injected into areas where the skin is red, bruised, tender, hard or areas where there are scars.
Pause or slow down delivery rate if the patient experiences pain. In the event pain is not alleviated by slowing down the injection, a second injection site may be chosen on the opposite side of the abdomen to deliver the remainder of the dose.
During treatment with DARZALEX FASPRO, do not administer other medications for subcutaneous use at the same site as DARZALEX FASPRO.
Any waste material should be disposed in accordance with local requirements.
Overdosage
Symptoms and signs: There has been no experience of overdosage in clinical studies with DARZALEX FASPRO subcutaneous formulation.
Treatment: There is no known specific antidote for DARZALEX FASPRO overdose. In the event of an overdose, the patient should be monitored for any signs or symptoms of adverse effects and appropriate symptomatic treatment be instituted immediately.
Contraindications
Patients with a history of severe hypersensitivity to daratumumab or any of the excipients.
Special Precautions
Infusion-related reactions: DARZALEX FASPRO can cause severe and/or serious infusion-related reactions (IRRs), including anaphylactic reactions. In clinical trials, approximately 9% (77/898) of patients experienced an infusion-related reaction. Most IRRs occurred following the first injection and were Grade 1-2 (see Adverse Reactions). IRRs occurring with subsequent injections were seen in 1% of patients.
The median time to onset of IRRs following DARZALEX FASPRO was 3.2 hours (range 0.07-83 hours). The majority of IRRs occurred on the day of treatment. Delayed IRRs have occurred in 1% of patients.
Signs and symptoms of IRRs may include respiratory symptoms, such as nasal congestion, cough, throat irritation, allergic rhinitis, wheezing as well as pyrexia, chest pain, pruritus, chills, vomiting, nausea, hypotension and blurred vision. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, tachycardia and ocular adverse events (including choroidal effusion, acute myopia and acute angle closure glaucoma) (see Adverse Reactions).
Pre-medicate patients with antihistamines, antipyretics and corticosteroids. Patients should be monitored and counselled regarding IRRs, especially during and following the first and second injections. If an anaphylactic reaction or life-threatening (Grade 4) reactions occur, institute appropriate emergency care and permanently discontinue DARZALEX FASPRO.
To reduce the risk of delayed IRRs, administer oral corticosteroids to all patients following DARZALEX FASPRO injections. Patients with a history of chronic obstructive pulmonary disease may require additional post-injection medications to manage respiratory complications. Consider prescribing short- and long-acting bronchodilators and inhaled corticosteroids for patients with chronic obstructive pulmonary disease. If ocular symptoms, interrupt DARZALEX FASPRO infusion and seek immediate ophthalmologic evaluation prior to restarting DARZALEX FASPRO (see Dosage & Administration).
Neutropenia/Thrombocytopenia: Daratumumab may increase neutropenia and thrombocytopenia induced by background therapy (see Adverse Reactions).
Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. DARZALEX FASPRO dose delay may be required to allow recovery of blood cell counts. In lower body weight patients receiving DARZALEX FASPRO subcutaneous formulation, higher rates of neutropenia were observed; however, this was not associated with higher rates of serious infections. No dose reduction of DARZALEX FASPRO is recommended. Consider supportive care with transfusions or growth factors.
Interference with indirect antiglobulin test (indirect Coombs test): Daratumumab binds to CD38 found at low levels on red blood cells (RBCs) and may result in a positive indirect Coombs test. Daratumumab-mediated positive indirect Coombs test may persist for up to 6 months after the last daratumumab administration. It should be recognized that daratumumab bound to RBCs may mask detection of antibodies to minor antigens in the patient's serum. The determination of a patient's ABO and Rh blood type are not impacted.
Type and screen patients prior to starting DARZALEX FASPRO. Phenotyping may be considered prior to starting daratumumab treatment as per local practice. Red blood cell genotyping is not impacted by daratumumab and may be performed at any time.
In the event of a planned transfusion notify blood transfusion centers of this interference with indirect antiglobulin tests (see Interactions). If an emergency transfusion is required, non-cross-matched ABO/RhD-compatible RBCs can be given per local blood bank practices.
Interference with determination of complete response: Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both, the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.
Hepatitis B Virus (HBV) reactivation: Hepatitis B virus (HBV) reactivation, in some cases fatal, has been reported in patients treated with daratumumab. HBV screening should be performed in all patients before initiation of treatment with DARZALEX FASPRO.
For patients with evidence of positive HBV serology, monitor for clinical and laboratory signs of HBV reactivation during, and for at least six months following the end of DARZALEX FASPRO treatment. Manage patients according to current clinical guidelines. Consider consulting a hepatitis disease expert as clinically indicated.
In patients who develop reactivation of HBV while on DARZALEX FASPRO, suspend treatment with DARZALEX FASPRO and any concomitant steroids, chemotherapy, and institute appropriate treatment. Resumption of DARZALEX FASPRO treatment in patients whose HBV reactivation is adequately controlled should be discussed with physicians with expertise in managing HBV.
Body weight (>120 kg): There is a potential for reduced efficacy with DARZALEX FASPRO solution for subcutaneous injection in patients with body weight >120 kg.
Excipients: This medicinal product contains sorbitol (E420). Patients with hereditary fructose intolerance (HFI) should not be given this medicinal product.
This medicinal product also contains less than 1 mmol (23 mg) sodium per dose, that is to say essentially 'sodium-free'.
Effects on Ability to Drive and Use Machines: DARZALEX FASPRO has no or negligible influence on the ability to drive and use machines. However, fatigue has been reported in patients taking daratumumab and this should be taken into account when driving or using machines.
Use In Pregnancy & Lactation
Pregnancy: There are no human or animal data to assess the risk of DARZALEX FASPRO use during pregnancy. IgG1 monoclonal antibodies are known to cross the placenta after the first trimester of pregnancy. Therefore DARZALEX FASPRO should not be used during pregnancy unless the benefit of treatment to the woman is considered to outweigh the potential risks to the fetus. If the patient becomes pregnant while taking this drug, the patient should be informed of the potential risk to the fetus.
To avoid exposure to the fetus, women of reproductive potential should use effective contraception during and for 3 months after cessation of DARZALEX FASPRO treatment.
Breast-feeding: It is not known whether daratumumab is excreted into human or animal milk or affects milk production. There are no studies to assess the effect of daratumumab on the breast-fed infant.
Maternal IgG is excreted in human milk, but does not enter the neonatal and infant circulations in substantial amounts as they are degraded in the gastrointestinal tract and not absorbed. Because the risks of DARZALEX FASPRO to the infant from oral ingestion are unknown, a decision should be made whether to discontinue breast-feeding, or discontinue DARZALEX FASPRO therapy, taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.
Fertility: No data are available to determine potential effects of daratumumab on fertility in males or females.
Adverse Reactions
Adverse reactions are adverse events that were considered to be reasonably associated with the use of daratumumab based on the comprehensive assessment of the available adverse event information. A causal relationship with daratumumab cannot be reliably established in individual cases. Further, because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Experience with DARZALEX FASPRO (subcutaneous daratumumab): The safety data of DARZALEX FASPRO subcutaneous (SC) formulation (1800 mg) was established in 638 patients with multiple myeloma (MM) including 260 patients from a Phase 3 active-controlled trial (Study MMY3012) who received DARZALEX FASPRO SC formulation as monotherapy, 149 patients from a Phase 3 active-controlled trial (Study MMY3013) who received DARZALEX FASPRO SC formulation in combination with pomalidomide and dexamethasone (D-Pd), and three open-label, clinical trials in which patients received DARZALEX FASPRO SC formulation either as monotherapy (N=31; MMY1004 and MMY1008) and MMY2040 in which patients received DARZALEX FASPRO SC formulation in combination with either bortezomib, melphalan and prednisone (D-VMP, n=67), lenalidomide and dexamethasone (D-Rd, n=65) or carfilzomib and dexamethasone (D-Kd, n=66).
The safety data of DARZALEX FASPRO SC formulation (1800 mg) was established in patients with newly diagnosed AL amyloidosis from a Phase 3 active-controlled trial (Study AMY3001) in which patients received DARZALEX FASPRO SC formulation in combination with bortezomib, cyclophosphamide and dexamethasone (D-VCd, n=193).
Monotherapy-relapsed/refractory multiple myeloma: MMY3012, a Phase 3 randomized, study compared treatment with DARZALEX FASPRO SC formulation (1800 mg) vs. intravenous (16 mg/kg) daratumumab in patients with relapsed or refractory multiple myeloma. The median DARZALEX FASPRO SC formulation treatment duration was 5.5 months (range: 0.03 to 19.35 months) and 6.0 months (range: 0.03 to 16.69 months) for intravenous daratumumab. The most common adverse reactions of any grade (≥20% patients) with DARZALEX FASPRO SC formulation were upper respiratory tract infections. Pneumonia was the only serious adverse reaction occurring in ≥5% of patients (6% IV vs. 6% SC).
Table 17 as follows lists the adverse reactions that occurred in patients who received DARZALEX FASPRO SC formulation or intravenous daratumumab in Study MMY3012. (See Table 17.)

Combination treatment for AL Amyloidosis: The safety of DARZALEX FASPRO SC formulation (1800 mg) with bortezomib, cyclophosphamide and dexamethasone (D-VCd) compared to bortezomib, cyclophosphamide and dexamethasone (VCd) in patients with newly diagnosed AL amyloidosis was evaluated in an open-label, randomized, Phase 3 study, AMY3001. The median treatment duration was 9.6 months (range: 0.03 to 21.16 months) for D-VCd and 5.3 months (range: 0.03 to 7.33 months) for VCd.
Serious adverse reactions occurred in 43% of patients who received DARZALEX FASPRO in combination with VCd. Serious adverse reactions that occurred in at least 5% of patients in the DARZALEX FASPRO-VCd arm were pneumonia (9%), cardiac failure (8%), and sepsis (5%). Fatal adverse reactions occurred in 11% of patients. Fatal adverse reactions that occurred in more than one patient included cardiac arrest (4%), sudden death (3%), cardiac failure (3%), and sepsis (1%).
Permanent discontinuation of DARZALEX FASPRO due to an adverse reaction occurred in 5% of patients. Adverse reactions resulting in permanent discontinuation of DARZALEX FASPRO in more than one patient were pneumonia, sepsis, and cardiac failure.
Dosing interruptions (defined as dose delays or skipped doses) due to an adverse reaction occurred in 36% of patients who received DARZALEX FASPRO. Adverse reactions which required a dosage interruption in ≥3% of patients included upper respiratory tract infection (9%), pneumonia (6%), cardiac failure (4%), fatigue (3%), herpes zoster (3%), dyspnea (3%), and neutropenia (3%).
The most common adverse reactions of any grade (≥20%) were upper respiratory tract infection, diarrhea, constipation, peripheral sensory neuropathy, dyspnea and cough. Serious adverse reactions with a 2% greater incidence in the D-VCd arm compared to the VCd arm were pneumonia (D-VCd 9% vs VCd 6%) and sepsis (D-VCd 5% vs VCd 1%).

Experience with intravenous daratumumab combination therapies: The safety of intravenous (IV) daratumumab (16 mg/kg) has been established in 1910 patients with multiple myeloma including 1772 patients from five Phase 3 active-controlled trials who received IV daratumumab in combination with either lenalidomide and dexamethasone (D-Rd, n=283; MMY3003), bortezomib and dexamethasone (D-Vd, n=243; MMY3004), bortezomib, melphalan and prednisone (D-VMP, n=346; MMY3007), or lenalidomide and dexamethasone (D-Rd, n=364; MMY3008), or bortezomib and thalidomide and dexamethasone (D-VTd, n=536; MMY3006) and two open-label, clinical trials in which patients received IV daratumumab either in combination with pomalidomide and dexamethasone (D-Pd, n=103; MMY1001) or in combination with lenalidomide and dexamethasone (n=35).
Adverse reactions in Table 25 reflect exposure to IV daratumumab for a median treatment duration as follows: MMY3008: 25.3 months (range: 0.1 to 40.44 months) for the daratumumab-lenalidomide-dexamethasone (D-Rd) group; 21.3 months (range: 0.03 to 40.64 months) for the lenalidomide-dexamethasone (Rd) group.
MMY3007: 14.7 months (range: 0 to 25.8 months) for the daratumumab-bortezomib, melphalan-prednisone (D-VMP) group; 12 months (range: 0.1 to 14.9 months) for the VMP group.
MMY3003: 13.1 months (range: 0 to 20.7 months) for the daratumumab-lenalidomide-dexamethasone (D-Rd) group; 12.3 months (range: 0.2 to 20.1 months) for the lenalidomide-dexamethasone (Rd) group.
MMY3004: 6.5 months (range: 0 to 14.8 months) for the daratumumab-bortezomib-dexamethasone (D-Vd) group; 5.2 months (range: 0.2 to 8.0 months) for the bortezomib-dexamethasone (Vd) group.
Additionally, adverse reactions described in Table 25 reflect exposure to IV daratumumab up to day 100 post-transplant in a Phase 3 active-controlled study MMY3006 (see Pharmacology: Pharmacodynamics: Clinical Studies under Actions). The median duration of induction/ASCT/consolidation treatment was 8.9 months (range: 7.0 to 12.0 months) for the D-VTd group and 8.7 months (range: 6.4 to 11.5 months) for the VTd group.
The most frequent adverse reactions (≥20%) were infusion-related reactions, fatigue, asthenia, nausea, diarrhea, constipation, decreased appetite, vomiting, muscle spasms, arthralgia, back pain, chills, pyrexia, dizziness, insomnia, cough, dyspnea, peripheral edema, peripheral sensory neuropathy, bronchitis, pneumonia, and upper respiratory tract infection. Serious adverse reactions with a 2% higher incidence in the IV daratumumab arms were pneumonia, bronchitis, upper respiratory tract infection, sepsis, pulmonary edema, influenza, pyrexia, dehydration, diarrhea, and atrial fibrillation.

Combination treatment with twice-weekly (20/56 mg/m2) carfilzomib and dexamethasone: Adverse reactions described in the table as follows reflect exposure to DARZALEX for a median treatment duration of 16.1 months (range: 0.1 to 23.7 months) for the daratumumab-carfilzomib-dexamethasone (DKd) group and median treatment duration of 9.3 months (range: 0.1 to 22.4 months) for the carfilzomib-dexamethasone group (Kd) in Phase 3 active-controlled study (Study 20160275). The most frequent (>20%) adverse reactions were infusion reactions, diarrhea, fatigue, upper respiratory tract infection, and pneumonia. Serious adverse reactions with a 2% greater incidence in the DKd arm compared to the Kd arm were pneumonia (DKd 14% vs Kd 11%), sepsis (DKd 6% vs Kd 3%), influenza (DKd 4% vs Kd 1%), pyrexia (DKd 4% vs Kd 2%), bronchitis (DKd 2% vs Kd 0%), and diarrhea (DKd 2% vs Kd 0%). Fatal events within 30 days of treatment cessation, regardless of causality, were reported in 10% of all patients treated with DKd versus 5% of patients treated with Kd and the most common cause was infection. Within the DKd group, fatal events occurred in 15% of the patients >65 years and 6% of the patients <65 years (see Infections, Other special population as follows).
Pre-specified infusion reaction-related terms that occurred on the same date or next date of any daratumumab dosing was 18% in the DKd arm and on the same date or next date of first daratumumab dosing was 12& in the DKd arm. Infusion reaction-related terms that occurred on the same date of any carfilzomib dosing was 41% in the DKd arm compared to 28% in the KD arm and on the same date of first carfilzomib dosing was 13% in the DKd arm compared to 1% in the Kd arm.

Monotherapy: The data described as follows reflect exposure to DARZALEX in three pooled open-label clinical studies that included 156 patients with relapsed and refractory multiple myeloma treated with DARZALEX at 16 mg/kg. The median duration of DARZALEX treatment was 3.3 months, with the longest duration of treatment being 14.2 months.
Adverse reactions occurring at a rate of ≥10% are presented in the table as follows. The most frequently reported adverse reactions (≥20%) were IRRs, fatigue, nausea, back pain, anemia, neutropenia and thrombocytopenia. Four percent of patients discontinued DARZALEX treatment due to adverse reactions, none of which were considered drug-related.
Frequencies are defined as very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1000 to <1/100), rare (≥1/10000 to <1/1000) and very rare (<1/10000). (See Table 31.)

Infusion-related reactions: In clinical trials (monotherapy and combination treatments; N=898) with DARZALEX FASPRO SC formulation, the incidence of any grade infusion-related reactions was 8.2% with the first injection of DARZALEX FASPRO SC formulation (1800 mg, Week 1), 0.4% with the Week 2 injection, and 1.1% with subsequent injections. Grade 3 IRRs were seen in 1.0% of patients. No patients had Grade 4 IRRs.
Signs and symptoms of IRRs may include respiratory symptoms, such as nasal congestion, cough, throat irritation, allergic rhinitis, wheezing as well as pyrexia, chest pain, pruritis, chills, vomiting, nausea, and hypotension. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension and tachycardia (see Precautions).
Injection site reactions (ISRs): In clinical trials (N=898) with DARZALEX FASPRO SC formulation, the incidence of any grade injection site reaction was 7.7%. There were no Grade 3 or 4 ISRs. The most common (≥1%) ISRs was erythema.
Infections: In patients with multiple myeloma receiving daratumumab monotherapy, the overall incidence of infections was similar between DARZALEX FASPRO SC formulation (52.9%) and IV daratumumab groups (50.0%). Grade 3 or 4 infections also occurred at similar frequencies between DARZALEX FASPRO SC formulation (11.7%) and IV daratumumab (14.3%). Most infections were manageable and rarely led to treatment discontinuation. Pneumonia was the most commonly reported Grade 3 or 4 infection across studies. In active-controlled studies, discontinuations from treatment due to infections occurred in 1-4% of patients. Fatal infections were primarily due to pneumonia and sepsis.
In patients with multiple myeloma receiving intravenous daratumumab combination therapy, the following infections were reported: Grade 3 or 4 infections: Relapsed/refractory patient studies: D-Vd: 21%, Vd: 19%; D-Rd: 28%, Rd: 23%; D-Pd: 28%; D-Kda: 36%, Kda: 27%; D-Kdb: 21%.
awhere carfilzomib 20/56 mg/m2 was administered twice-weekly.
bwhere carfilzomib 20/70 mg/m2 was administered once-weekly.
Newly diagnosed patient studies: D-VMP: 23%, VMP: 15%; D-Rd: 32%, Rd: 23%; D-VTd: 22%, VTd: 20%.
Grade 5 (fatal) infections: Relapsed/refractory patient studies: D-Vd: 1%, Vd: 2%; D-Rd: 2%, Rd: 1%; D-Pd: 2%; D-Kda: 5%, Kda: 3%; D-Kdb: 0%.
awhere carfilzomib 20/56 mg/m2 was administered twice-weekly.
bwhere carfilzomib 20/70 mg/m2 was administered once-weekly.
Newly diagnosed patient studies: D-VMP: 1%, VMP: 1%; D-Rd: 2%, Rd: 2%; D-VTd: 0%, VTd: 0%.
In patients with multiple myeloma receiving DARZALEX FASPRO SC formulation combination therapy, the following were reported: Grade 3 or 4 infections: D-Pd: 28%, Pd: 23%; Grade 5 (fatal) infections: D-Pd: 5%, Pd: 3%.
In patients with AL amyloidosis receiving DARZALEX FASPRO SC formulation combination therapy, the following were reported: Grade 3 or 4 infections: D-VCd: 17%, VCd: 10%; Grade 5 (fatal) infections: D-VCd: 1%, VCd: 1%.
Haemolysis: There is a theoretical risk of haemolysis. Continuous monitoring for this safety signal will be performed in clinical studies and post-marketing safety data.
Cardiac disorders and AL amyloidosis-related cardiomyopathy: The majority of patients in AMY3001 had AL amyloidosis-related cardiomyopathy at baseline (D-VCd 72% vs. VCd 71%). Grade 3 or 4 cardiac disorders occurred in 11% of D-VCd patients compared to 10% of VCd patients, while serious cardiac disorders occurred in 16% vs. 13% of D-VCd and VCd patients, respectively. Serious cardiac disorders occurring in ≥2% of patients included cardiac failure (D-VCd 6.2% vs. VCd 4.3%), cardiac arrest (D-VCd 3.6% vs. VCd 1.6%) and atrial fibrillation (D-VCd 2.1% vs. VCd 1.1%). All D-VCd patients who experienced serious or fatal cardiac disorders had AL amyloidosis-related cardiomyopathy at baseline. The longer median duration of treatment in the D-VCd arm compared to the VCd arm (9.6 months vs. 5.3 months, respectively) should be taken into consideration when comparing the frequency of cardiac disorders between the two treatment groups. Exposure-adjusted incidence rates (number of patients with the event per 100 patient-months at risk) of overall Grade 3 or 4 cardiac disorders (1.2 vs. 2.3), cardiac failure (0.5 vs. 0.6), cardiac arrest (0.1 vs. 0.0) and atrial fibrillation (0.2 vs. 0.1) were comparable in the D-VCd arm vs. the VCd arm, respectively.
With a median follow-up of 11.4 months, overall deaths (D-VCd 14% vs. VCd 15%) in Study AMY3001 were primarily due to AL amyloidosis-related cardiomyopathy in both treatment arms.
Other Adverse Reactions: Other adverse reactions reported in patients treated with daratumumab in clinical trials are listed in Table 32. (See Table 32.)

Other special population: In the phase III study MMY3007, which compared treatment with D-VMP to treatment with VMP in patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant, safety analysis of the subgroup of patients with an ECOG performance score of 2 (D-VMP: n=89, VMP: n=84), was consistent with the overall population.
Elderly: Of the 3615 patients who received daratumumab (n-898 SC; n=2717 IV) at the recommended dose, 38% were 65 to less than 75 years of age, and 16% were 75 years of age or older. No overall differences in effectiveness were observed based on age. The incidence of serious adverse reactions was higher in older than in younger patients (see as follows, Pharmacology: Pharmacodynamics: Clinical Studies under Actions). Among patients with relapsed and refractory multiple myeloma (n=2042), the most common serious adverse reactions that occurred more frequently in elderly (≥65 years of age) were pneumonia and sepsis. Among patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant (n=777), the most common serious adverse reaction that occurred more frequently in elderly (≥75 years of age) was pneumonia. Among patients with newly diagnosed AL amyloidosis (n=193), the most common serious adverse reaction that occurred more frequently in elderly (≥65 years of age) was pneumonia.
Postmarketing data: In addition to the previously mentioned, adverse reactions identified during postmarketing experience with daratumumab are included in Table 33. The frequencies are provided according to the following convention: Very common ≥1/10; Common ≥1/100 to <1/10; Uncommon ≥1/1000 to <1/100; Rare ≥1/10000 to <1/1000; Very rare <1/10000, including isolated reports; Not known frequency cannot be estimated from the available data.
In Table 33, adverse reactions are presented by frequency category based on spontaneous reporting rates, as well as frequency category based on precise incidence in a clinical trial, when known. (See Table 33.)

Drug Interactions
Drug-Drug Interactions: No formal drug-drug interaction studies have been performed.
As an IgG1қ monoclonal antibody, renal excretion and hepatic enzyme-mediated metabolism of intact daratumumab are unlikely to represent major elimination routes. As such, variations in drug-metabolizing enzymes are not expected to affect the elimination of daratumumab. Due to the high affinity to a unique epitope on CD38, daratumumab is not anticipated to alter drug-metabolizing enzymes.
Clinical pharmacokinetic assessments with daratumumab IV or SC formulations and lenalidomide, pomalidomide, thalidomide, bortezomib, melphalan, prednisone, carfilzomib, cyclophosphamide and dexamethasone indicated no clinically-relevant drug-drug interaction between daratumumab and these small molecule medicinal products.
Effects of DARZALEX FASPRO on laboratory tests: Interference with indirect antiglobulin test (indirect Coombs test): Daratumumab binds to CD38 on RBCs and interferes with compatibility testing, including antibody screening and cross-matching. Daratumumab interference mitigation methods include treating reagent RBCs with dithiothreitol (DTT) to disrupt daratumumab binding or genotyping. Since the Kell blood group system is also sensitive to DTT treatment, Kell-negative units should be supplied after ruling out or identifying alloantibodies using DTT-treated RBCs.
Interference with serum protein electrophoresis and immunofixation tests: Daratumumab may be detected on serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for monitoring disease monoclonal immunoglobulins (M protein). This can lead to false positive SPE and IFE assay results for patients with IgG kappa myeloma protein impacting initial assessment of Complete Responses (CRs) by International Myeloma Working Group (IMWG) criteria. In patients with persistent very good partial response (VGPR), where daratumumab interference is suspected, consider using a validated daratumumab-specific IFE assay to distinguish daratumumab from any remaining endogenous M protein in the patient's serum, to facilitate determination of a CR (see Pharmacology: Pharmacodynamics: Clinical Studies under Actions).
