Generic Name: daratumumab
Dosage Form: injection, solution, concentrate
Indications and Usage for Darzalex
Darzalex is indicated for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent or who are double-refractory to a PI and an immunomodulatory agent.
This indication is approved under accelerated approval based on response rate [see Clinical Studies (14)]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
Darzalex Dosage and Administration
Recommended Dose and Schedule
- Administer pre-infusion and post-infusion medications [see Dosage and Administration (2.2)].
- Administer only as an intravenous infusion after dilution [see Dosage and Administration (2.4)].
- Darzalex should be administered by a healthcare professional, with immediate access to emergency equipment and appropriate medical support to manage infusion reactions if they occur [see Warnings and Precautions (5.1)].
The recommended dose of Darzalex is 16 mg/kg body weight administered as an intravenous infusion according to the following dosing schedule.
|Weekly||Weeks 1 to 8|
|Every two weeks||Weeks 9 to 24|
|Every four weeks||Week 25 onwards until disease progression|
If a planned dose of Darzalex is missed, administer the dose as soon as possible and adjust the dosing schedule accordingly, maintaining the treatment interval.
Administer Darzalex infusion intravenously at the appropriate infusion rate. Consider incremental escalation of the infusion rate only in the absence of infusion reactions with the previous infusion of Darzalex as defined in Table 2.
|Dilution volume||Initial rate (first hour)||Rate increment||Maximum rate|
|First infusion||1000 mL||50 mL/hour||50 mL/hour every hour||200 mL/hour|
|Second infusion*||500 mL||50 mL/hour||50 mL/hour every hour||200 mL/hour|
|Subsequent infusions†||500 mL||100 mL/hour||50 mL/hour every hour||200 mL/hour|
For infusion reactions of any grade/severity, immediately interrupt the Darzalex infusion and manage symptoms. Management of infusion reactions may further require reduction in the rate of infusion, or treatment discontinuation of Darzalex as outlined below [see Warnings and Precautions (5.1)].
- Grade 1–2 (mild to moderate): Once reaction symptoms resolve, resume the infusion at no more than half the rate at which the reaction occurred. If the patient does not experience any further reaction symptoms, infusion rate escalation may resume at increments and intervals as appropriate (Table 2).
- Grade 3 (severe): If the intensity of the reaction decreases to Grade 2 or lower, consider restarting the infusion at no more than half the rate at which the reaction occurred. If the patient does not experience additional symptoms, resume infusion rate escalation at increments and intervals as outlined in Table 2. Repeat the procedure above in the event of recurrence of Grade 3 symptoms. Permanently discontinue Darzalex upon the third occurrence of a Grade 3 or greater infusion reaction.
- Grade 4 (life threatening): Permanently discontinue Darzalex treatment.
Recommended Concomitant Medications
Administer pre-infusion medications to reduce the risk of infusion reactions to all patients approximately 1 hour prior to every infusion of Darzalex as follows:
- intravenous corticosteroid (methylprednisolone 100 mg, or equivalent dose of an intermediate-acting or long-acting corticosteroid), plus
- oral antipyretics (acetaminophen 650 to 1000 mg), plus
- oral or intravenous antihistamine (diphenhydramine 25 to 50 mg or equivalent).
Following the second infusion, the dose of corticosteroid may be reduced (methylprednisolone 60 mg intravenously).
Administer post-infusion medication to reduce the risk of delayed infusion reactions to all patients as follows:
- oral corticosteroid (20 mg methylprednisolone or equivalent dose of a corticosteroid in accordance with local standards) on the first and second day after all infusions.
For patients with a history of obstructive pulmonary disorder, consider prescribing post-infusion medications such as short and long-acting bronchodilators, and inhaled corticosteroids. Following the first four infusions, if the patient experiences no major infusion reactions, these additional inhaled post-infusion medications may be discontinued.
Prophylaxis for Herpes Zoster Reactivation
Initiate antiviral prophylaxis to prevent herpes zoster reactivation within 1 week of starting Darzalex and continue for 3 months following treatment [see Adverse Reactions (6.1)].
Preparation for Administration
Darzalex is for single use only.
Prepare the solution for infusion using aseptic technique as follows:
- Calculate the dose (mg), total volume (mL) of Darzalex solution required and the number of Darzalex vials needed based on patient actual body weight.
- Check that the Darzalex solution is colorless to pale yellow. Do not use if opaque particles, discoloration or other foreign particles are present.
- Using aseptic technique, remove a volume of 0.9% Sodium Chloride Injection, USP from the infusion bag/container that is equal to the required volume of Darzalex solution.
- Withdraw the necessary amount of Darzalex solution and dilute to the appropriate volume by adding to the infusion bag/container containing 0.9% Sodium Chloride Injection, USP as specified in Table 2 [see Dosage and Administration (2.1)]. Infusion bags/containers must be made of polyvinylchloride (PVC), polypropylene (PP), polyethylene (PE) or polyolefin blend (PP+PE). Dilute under appropriate aseptic conditions. Discard any unused portion left in the vial.
- Gently invert the bag/container to mix the solution. Do not shake.
- Following dilution the infusion bag/container may be stored for up to 24 hours in a refrigerator at 2°C to 8°C (36°F to 46°F), protected from light. Do not freeze. After allowing the bag/container to come to room temperature, use immediately since Darzalex solutions do not contain a preservative.
- Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The diluted solution may develop very small, translucent to white proteinaceous particles, as daratumumab is a protein. Do not use if visibly opaque particles, discoloration or foreign particles are observed.
- Administer the diluted solution by intravenous infusion using an infusion set fitted with a flow regulator and with an in-line, sterile, non-pyrogenic, low protein-binding polyethersulfone (PES) filter (pore size 0.22 or 0.2 micrometer). Polyurethane (PU), polybutadiene (PBD), PVC, PP or PE administration sets must be used.
- Infusion should be completed within 15 hours.
- Do not store any unused portion of the infusion solution for reuse. Any unused product or waste material should be disposed of in accordance with local requirements.
- Do not infuse Darzalex concomitantly in the same intravenous line with other agents.
Dosage Forms and Strengths
Darzalex is a colorless to pale yellow, preservative-free solution available as:
- 100 mg/5 mL (20 mg/mL) in a single-dose vial.
- 400 mg/20 mL (20 mg/mL) in a single-dose vial.
Warnings and Precautions
Darzalex can cause severe infusion reactions. Approximately half of all patients experienced a reaction, most during the first infusion.
Infusion reactions can also occur with subsequent infusions. Nearly all reactions occurred during infusion or within 4 hours of completing Darzalex. Prior to the introduction of post-infusion medication in clinical trials, infusion reactions occurred up to 48 hours after infusion.
Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, and hypertension. Signs and symptoms may include respiratory symptoms, such as cough, wheezing, larynx and throat tightness and irritation, laryngeal edema, pulmonary edema, nasal congestion, and allergic rhinitis. Less common symptoms were hypotension, headache, rash, urticaria, pruritus, nausea, vomiting, and chills [see Adverse Reactions (6.1)].
Pre-medicate patients with antihistamines, antipyretics and corticosteroids. Frequently monitor patients during the entire infusion. Interrupt Darzalex infusion for reactions of any severity and institute medical management as needed. Permanently discontinue Darzalex therapy for life-threatening (Grade 4) reactions. For patients with Grade 1, 2, or 3 reactions, reduce the infusion rate when re-starting the infusion [see Dosage and Administration (2.1)].
To reduce the risk of delayed infusion reactions, administer oral corticosteroids to all patients the first and second day after all infusions. Patients with a history of obstructive pulmonary disorders may require additional post-infusion medications to manage respiratory complications. Consider prescribing short- and long-acting bronchodilators and inhaled corticosteroids for patients with obstructive pulmonary disorders.
Interference with Serological Testing
Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive Indirect Antiglobulin Test (Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab infusion. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient's serum1 [see References (15)]. The determination of a patient's ABO and Rh blood type are not impacted [see Drug Interactions (7.1)].
Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received Darzalex. Type and screen patients prior to starting Darzalex.
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 [see Drug Interactions (7.1)]. This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.
The following serious adverse reactions are also described elsewhere in the labeling:
- Infusion reactions [see Warning and Precautions (5.1)].
Adverse Reactions in Clinical Trials
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 practice.
The safety data reflect exposure to Darzalex in 156 adult patients with relapsed and refractory multiple myeloma treated with Darzalex at 16 mg/kg in three open-label, clinical trials. The median duration of exposure was 3.3 months (range: 0.03 to 20.4 months).
Serious adverse reactions were reported in 51 (33%) patients. The most frequent serious adverse reactions were pneumonia (6%), general physical health deterioration (3%), and pyrexia (3%).
Adverse reactions resulted in treatment delay for 24 (15%) patients, most frequently for infections. Adverse reactions resulted in discontinuations for 6 (4%) patients.
Adverse reactions occurring in at least 10% of patients are presented in Table 3. Table 4 describes Grade 3–4 laboratory abnormalities reported at a rate of ≥10%.
|System Organ Class||Darzalex 16 mg/kg
|Adverse Reaction||Any Grade||Grade 3||Grade 4|
|General disorders and administration site conditions|
|Respiratory, thoracic and mediastinal disorders|
|Musculoskeletal and connective tissue disorders|
|Pain in extremity||15||1||0|
|Musculoskeletal chest pain||12||1||0|
|Infections and infestations|
|Upper respiratory tract infection||20||1||0|
|Metabolism and nutrition disorders|
|Nervous system disorders|
|Daratumumab 16 mg/kg (N=156)|
|All Grade (%)||Grade 3 (%)||Grade 4 (%)|
The incidence of any grade infusion reactions was 46% with the first infusion of Darzalex, 5% with the second infusion, and 4% with subsequent infusions. None of the reactions with second or subsequent infusions were Grade 3 or higher.
The median time to onset of a reaction was 1.5 hours (range: 0.02 to 9.3 hours). The incidence of infusion interruptions due to reactions was 37%. Median durations of infusion for the 1st, 2nd and subsequent infusions were 7.0, 4.6 and 3.4 hours respectively.
Severe infusion reactions included bronchospasm, dyspnea, hypoxia, and hypertension (<2% each). Common any grade adverse infusion reactions (≥5%) were nasal congestion, cough, chills, rhinitis allergic, throat irritation, dyspnea, and nausea.
Herpes Zoster Virus Reactivation
Prophylaxis for Herpes Zoster Virus reactivation was recommended for patients in some clinical trials of Darzalex. Systemic anti-viral medications were used in 73% of patients. Herpes zoster was reported in 3% of patients.
As with all therapeutic proteins, there is the potential for immunogenicity. In an open-label, clinical trial of patients with relapsed or refractory multiple myeloma treated with Darzalex, 111 patients were evaluated for anti-therapeutic antibody (ATA) responses to daratumumab at multiple time points during treatment and up to 8 weeks following the end of treatment using an electrochemiluminescence-based immunoassay. Following the start of Darzalex treatment, none of the patients tested positive for anti-daratumumab antibodies. However, this assay has limitations in detecting anti-daratumumab antibodies in the presence of high concentrations of daratumumab; therefore, the incidence of antibody development might not have been reliably determined.
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.
No drug interaction studies have been performed.
Effects of Daratumumab on Laboratory Tests
Interference with Indirect Antiglobulin Tests (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 binding1 [see References (15)] or genotyping. Since the Kell blood group system is also sensitive to DTT treatment, K-negative units should be supplied after ruling out or identifying alloantibodies using DTT-treated RBCs.
If an emergency transfusion is required, non-cross-matched ABO/RhD-compatible RBCs can be given per local blood bank practices.
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 by International Myeloma Working Group (IMWG) criteria. In patients with persistent very good partial response, consider other methods to evaluate the depth of response.
USE IN SPECIFIC POPULATIONS
There are no human data to inform a risk with use of Darzalex during pregnancy. Animal studies have not been conducted. However, there are clinical considerations [see Clinical Considerations]. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.
Fetal/Neonatal Adverse Reactions
Immunoglobulin G1 (IgG1) monoclonal antibodies are transferred across the placenta. Based on its mechanism of action, Darzalex may cause fetal myeloid or lymphoid-cell depletion and decreased bone density. Defer administering live vaccines to neonates and infants exposed to Darzalex in utero until a hematology evaluation is completed.
Mice that were genetically modified to eliminate all CD38 expression (CD38 knockout mice) had reduced bone density at birth that recovered by 5 months of age. In cynomolgus monkeys exposed during pregnancy to other monoclonal antibodies that affect leukocyte populations, infant monkeys had a reversible reduction in leukocytes.
There is no information regarding the presence of daratumumab in human milk, the effects on the breastfed infant, or the effects on milk production. Human IgG is known to be present in human milk. Published data suggest that antibodies in breast milk do not enter the neonatal and infant circulations in substantial amounts.
The developmental and health benefits of breast-feeding should be considered along with the mother's clinical need for Darzalex and any potential adverse effects on the breast-fed child from Darzalex or from the underlying maternal condition.
Females and Males of Reproductive Potential
To avoid exposure to the fetus, women of reproductive potential should use effective contraception during treatment and for 3 months after cessation of Darzalex treatment.
Safety and effectiveness of Darzalex in pediatric patients have not been established.
Of the 156 patients on the recommended dose, 45% were 65 years of age or older, and 10% were 75 years of age or older. No overall differences in safety or effectiveness were observed between these patients and younger patients [see Clinical Studies (14)].
Based on a population pharmacokinetic (PK) analysis no dosage adjustment is necessary for patients with pre-existing renal impairment [see Clinical Pharmacology (12.3)].
Based on a population PK analysis, no dosage adjustments are necessary for patients with mild hepatic impairment (Total Bilirubin [TB] 1.0× to 1.5× upper limit of normal [ULN] or aspartate aminotransferase [AST] >ULN). Daratumumab has not been studied in patients with moderate to severe hepatic impairment (TB >1.5× ULN and any AST) [see Clinical Pharmacology (12.3)].
The dose of Darzalex at which severe toxicity occurs is not known.
In the event of an overdose, monitor patients for any signs or symptoms of adverse effects and provide appropriate supportive treatment.
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. The molecular weight of daratumumab is approximately 148 kDa.
Darzalex is supplied as a colorless to pale yellow preservative-free solution for intravenous infusion in single-dose vials. The pH is 5.5. Darzalex must be diluted with 0.9% Sodium Chloride Injection, USP [see Dosage and Administration (2.3, 2.4)].
Each Darzalex single-dose 20 mL vial contains 400 mg daratumumab, glacial acetic acid (3.7 mg), mannitol (510 mg), polysorbate 20 (8 mg), sodium acetate trihydrate (59.3 mg), sodium chloride (70.1 mg), and water for injection.
Each Darzalex single-dose 5 mL vial contains 100 mg daratumumab, glacial acetic acid (0.9 mg), mannitol (127.5 mg), polysorbate 20 (2 mg), sodium acetate trihydrate (14.8 mg), sodium chloride (17.5 mg), and water for injection.
Darzalex - Clinical Pharmacology
Mechanism of Action
CD38 is a transmembrane glycoprotein (48 kDa) expressed on the surface of hematopoietic cells, including multiple myeloma and other cell types and tissues and has multiple functions, such as receptor mediated adhesion, signaling, and modulation of cyclase and hydrolase activity. Daratumumab is an IgG1κ human monoclonal antibody (mAb) that binds to CD38 and inhibits the growth of CD38 expressing tumor cells by inducing apoptosis directly through Fc mediated cross linking as well as by immune-mediated tumor cell lysis through complement dependent cytotoxicity (CDC), antibody dependent cell mediated cytotoxicity (ADCC) and antibody dependent cellular phagocytosis (ADCP). Myeloid derived suppressor cells (MDSCs) and a subset of regulatory T cells (CD38+Tregs) express CD38 and are susceptible to daratumumab mediated cell lysis.
NK cells express 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 treatment.
CD4+ and CD8+ T cell absolute counts, as well as their percentage of total lymphocytes, increased with Darzalex treatment in both the peripheral blood and bone marrow.
Darzalex as a large protein has a low likelihood of direct ion channel interactions. There is no evidence from non-clinical or clinical data to suggest that Darzalex has the potential to delay ventricular repolarization.
The pharmacokinetics (PK) of daratumumab following intravenous administration were evaluated in patients with relapsed and refractory multiple myeloma at dose levels from 0.1 mg/kg to 24 mg/kg, and included the recommended 16 mg/kg dose and regimen. The population PK analysis included 223 patients with multiple myeloma receiving Darzalex in two clinical trials (150 subjects received 16 mg/kg).
Over the dose range from 1 to 24 mg/kg, increases in area under the concentration-time curve (AUC) were more than dose-proportional. Clearance decreased with increasing dose and repeated dosing, indicating target-mediated pharmacokinetics.
Following the recommended schedule and dose of 16 mg/kg, the mean [standard deviation (SD)] serum Cmax value was 915 (410) µg/mL at the end of weekly dosing, approximately 2.9-fold higher than following the first infusion. The mean (SD) predose (trough) serum concentration at the end of weekly dosing was 573 (332) µg/mL.
Based on the population PK analysis, daratumumab steady state is achieved approximately 5 months into the every 4-week dosing period (by the 21st infusion), and the mean (SD) ratio of Cmax at steady-state to Cmax after the first dose was 1.6 (0.5). The mean (SD) linear clearance and mean (SD) central volume of distribution are estimated to be 171.4 (95.3) mL/day and 4.7 (1.3 L), respectively. The mean (SD) estimated terminal half-life associated with linear clearance was approximately 18 (9) days.
Population PK analyses indicated that the central volume of distribution and clearance of daratumumab increase with increasing body weight, supporting the body weight-based dosing regimen. Population PK analyses also showed that age (31 to 84 years) and gender do not have clinically important effects on the pharmacokinetics of daratumumab.
The population PK analysis included 71 patients with normal renal function (creatinine clearance [CrCL] ≥90 mL/min), 78 patients with mild renal impairment (CrCL <90 and ≥60 mL/min), 68 patients with moderate renal impairment (CrCL <60 and ≥30 mL/min), and 6 patients with severe renal impairment or end stage renal disease (CrCL <30 mL/min). No clinical differences in exposure to daratumumab were observed between patients with renal impairment and those with normal renal function [see Use in Specific Populations (8.6)].
The population PK analysis included 189 patients with normal hepatic function (TB and AST ≤ULN) and 34 with mild hepatic impairment (TB 1.0× to 1.5× ULN or AST>ULN) patients. No clinical differences in the exposure to daratumumab were observed between patients with mild hepatic impairment and those with normal hepatic function. Daratumumab has not been studied in patients with moderate (TB>1.5× to 3× ULN and any AST) or severe (TB>3× ULN and any AST) hepatic impairment.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No carcinogenicity or genotoxicity studies have been conducted with daratumumab. No animal studies have been performed to evaluate the potential effects of daratumumab on reproduction or development, or to determine potential effects on fertility in males or females.
Study 1, was an open-label trial evaluating Darzalex monotherapy 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. In 106 patients, Darzalex 16 mg/kg was administered with pre- and post-infusion medication. Treatment continued until unacceptable toxicity or 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 proteasome inhibitor (PI) and immunomodulatory agent, and 77% were refractory to alkylating agents.
Efficacy results were based on overall response rate as determined by the Independent Review Committee assessment using IMWG criteria (see Table 5).
|ORR = sCR+CR+VGPR+PR
CI = confidence interval
|Overall response rate (ORR)||31 (29.2%)|
|95% CI (%)||(20.8, 38.9)|
|Stringent complete response (sCR)||3 (2.8%)|
|Complete response (CR)||0|
|Very good partial response (VGPR)||10 (9.4%)|
|Partial response (PR)||18 (17.0%)|
The median time to response was 1 month (range: 0.9 to 5.6 months). The median duration of response was 7.4 months (range: 1.2 to 13.1+ months).
Study 2 was an open-label dose escalation trial evaluating Darzalex monotherapy in patients with relapsed or refractory multiple myeloma who had received at least 2 different cytoreductive therapies. In 42 patients, Darzalex 16 mg/kg was administered with pre- and post-infusion medication. Treatment continued until unacceptable toxicity or 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% of patients were refractory to both, a PI and an immunomodulatory agent, and 60% of patients were refractory to alkylating agents.
Overall response rate was 36% (95% CI: 21.6, 52.0%) with 1 CR and 3 VGPR. The median time to response was 1 month (range: 0.5 to 3.2 months). The median duration of response was not estimable (range: 2.2 to 13.1+ months).
