The following serious adverse reactions are also described elsewhere in the labeling:
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 described below reflects exposure to Дарзалекс (16 mg/kg) in 1166 patients with multiple myeloma including 872 patients from three Phase 3 active-controlled trials who received Дарзалекс in combination with either lenalidomide and dexamethasone (DRd, n=283; POLLUX), bortezomib and dexamethasone (DVd, n=243; CASTOR) or bortezomib, melphalan and prednisone (D-VMP, n=346; ALCYONE), and five open-label, clinical trials in which patients received Дарзалекс either in combination with pomalidomide and dexamethasone (DPd, n=103; EQUULEUS), in combination with lenalidomide and dexamethasone (n=35), or as monotherapy (n=156).
Newly Diagnosed Multiple Myeloma Combination Treatment with Bortezomib, Melphalan and PrednisoneAdverse reactions described in Table 5 reflect exposure to Дарзалекс (D-VMP arm) for a median treatment duration of 14.7 months (range: 0 to 25.8 months) and median treatment duration of 12 months (range: 0.1 to 14.9 months) for the VMP group in ALCYONE. The most frequent adverse reactions (≥20% with at least 5% greater frequency in the D-VMP arm) were infusion reactions, upper respiratory tract infection and edema peripheral. Serious adverse reactions with at least a 2% greater incidence in the D-VMP arm compared to the VMP arm were pneumonia (D-VMP 11% vs VMP 4%), upper respiratory tract infection (D-VMP 5% vs VMP 1%), and pulmonary edema (D-VMP 2% vs VMP 0%).

In clinical trials (monotherapy and combination treatments; N=1166) the incidence of any grade infusion reactions was 40% with the first infusion of Дарзалекс, 2% with the second infusion, and 4% with subsequent infusions. Less than 1% of patients had a Grade 3 infusion reaction with second or subsequent infusions. Grade 4 infusion reactions were reported in 2/1166 (0.2%) of patients.
The median time to onset of a reaction was 1.4 hours (range: 0 to 72.8 hours). The incidence of infusion modification due to reactions was 37%. Median durations of infusion for the 1st, 2nd and subsequent infusions were 7.0, 4.3, and 3.4 hours respectively.
Severe infusion reactions included bronchospasm, dyspnea, laryngeal edema, pulmonary edema, hypoxia, and hypertension. Other adverse infusion reactions included nasal congestion, cough, chills, throat irritation, vomiting and nausea.
Herpes Zoster Virus ReactivationProphylaxis for Herpes Zoster Virus reactivation was recommended for patients in some clinical trials of Дарзалекс. In monotherapy studies, herpes zoster was reported in 3% of patients. In the combination therapy studies, herpes zoster was reported in 2-5% of patients receiving Дарзалекс.
InfectionsIn patients receiving Дарзалекс combination therapy, Grade 3 or 4 infections were reported with Дарзалекс combinations and background therapies (DVd: 21%, Vd: 19%; DRd: 28%, Rd: 23%; D-VMP:23%, VMP:15%; DPd: 28%). Pneumonia was the most commonly reported severe (Grade 3 or 4) infection across studies. Discontinuations from treatment were reported in 3% versus 2% of patients in the DRd and Rd groups respectively, 4% versus 3% of patients in the DVd and Vd groups respectively, 1% each in the D-VMP and VMP groups respectively, and in 5% of patients receiving DPd. Fatal infections were generally balanced between the Дарзалекс containing regimens and active control arms (<2%) in the controlled studies and were primarily due to pneumonia and sepsis.
ImmunogenicityAs with all therapeutic proteins, there is the potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to daratumumab in the studies described below with the incidence of antibodies in other studies or to other products may be misleading. In clinical trials of patients with multiple myeloma treated w
Дарзалекс is indicated:
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 Дарзалекс treatment.
Cardiac ElectrophysiologyДарзалекс 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 Дарзалекс has the potential to delay ventricular repolarization.
Over the dose range from 1 to 24 mg/kg as monotherapy or 1 to 16 mg/kg of Дарзалекс in combination with other treatments, increases in area under the concentration-time curve (AUC) were more than dose-proportional.
Following the recommended dose of 16 mg/kg when Дарзалекс was administered as monotherapy or in combination therapy, the mean serum maximal concentration (Cmax) value at the end of weekly dosing, was approximately 2.7 to 3-fold higher compared to the mean serum Cmax following the first dose. The mean ± standard deviation (SD) trough serum concentration (Cmin) at the end of weekly dosing was 573 ± 332 µg/mL when Дарзалекс was administered as monotherapy and 502 ± 196 to 607 ± 231 µg/mL when Дарзалекс was administered as combination therapy. When Дарзалекс was administered as monotherapy, daratumumab steady state was 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.
DistributionAt the recommended dose of 16 mg/kg, the mean ± SD central volume of distribution was 4.7 ± 1.3 L when Дарзалекс was administered as monotherapy and 4.4 ± 1.5 L when Дарзалекс was administered as combination therapy.
EliminationDaratumumab clearance decreased with increasing dose and with multiple dosing. At the recommended dose of 16 mg/kg of Дарзалекс as monotherapy, the mean ± SD linear clearance was estimated to be 171.4 ± 95.3 mL/day. The mean ± SD estimated terminal half-life associated with linear clearance was 18 ± 9 days when Дарзалекс administered as monotherapy and a mean of 22-23 days when Дарзалекс was administered as combination therapy.
Included as part of the "PRECAUTIONS" Section
PRECAUTIONS Infusion ReactionsДарзалекс 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 Дарзалекс. 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, hypertension, laryngeal edema and pulmonary edema. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting and nausea. Less common symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, and hypotension.
Pre-medicate patients with antihistamines, antipyretics and corticosteroids. Frequently monitor patients during the entire infusion. Interrupt Дарзалекс infusion for reactions of any severity and institute medical management as needed. Permanently discontinue Дарзалекс 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.
To reduce the risk of delayed infusion reactions, administer oral corticosteroids to all patients following Дарзалекс infusions. Patients with a history of chronic obstructive pulmonary disease may require additional post-infusion medications to manage respiratory complications. Consider prescribing short-and long-acting bronchodilators and inhaled corticosteroids for patients with chronic obstructive pulmonary disease.
Interference With Serological TestingDaratumumab binds to CD38 on red blood cells (RBCs) and results in a positive Indirect Antiglobulin Test (Indirect 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 serum. The determination of a patient’s ABO and Rh blood type are not impacted.
Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received Дарзалекс. Type and screen patients prior to starting Дарзалекс.
NeutropeniaДарзалекс may increase neutropenia induced by background therapy.
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. Дарзалекс dose delay may be required to allow recovery of neutrophils. No dose reduction of Дарзалекс is recommended. Consider supportive care with growth factors.
ThrombocytopeniaДарзалекс may increase thrombocytopenia induced by background therapy.
Monitor complete blood cell counts periodically during treatment according to manufacturer’ prescribing information for background therapies. Дарзалекс dose delay may be required to allow recovery of platelets. No dose reduction of Дарзалекс is recommended. Consider supportive care with transfusions.
Interference With Determination Of Complete ResponseDaratumumab 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.
Patient Counseling InformationAdvise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION).
Infusion ReactionsAdvise patients to seek immediate medical attention for any of the following signs and symptoms of infusion reactions:
Advise patients to inform healthcare providers including blood transfusion centers/personnel that they are taking Дарзалекс, in the event of a planned transfusion.
Advise patients that Дарзалекс can affect the results of some tests used to determine complete response in some patients and additional tests may be needed to evaluate response.
Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of FertilityNo 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.
Use In Specific Populations Pregnancy Risk SummaryThere are no human data to inform a risk with use of Дарзалекс during pregnancy. Animal studies have not been conducted. However, there are clinical considerations. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.
Clinical ConsiderationsFetal/Neonatal Adverse Reactions
Immunoglobulin G1 (IgG1) monoclonal antibodies are transferred across the placenta. Based on its mechanism of action, Дарзалекс may cause fetal myeloid or lymphoid-cell depletion an decreased bone density. Defer administering live vaccines to neonates and infants exposed to Дарзалекс in utero until a hematology evaluation is completed.
DataAnimal Data
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.
Lactation Risk SummaryThere is no information regarding the presence of daratumumab in human milk, the effects on the breastfed child, 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 Дарзалекс and any potential adverse effects on the breast-fed child from Дарзалекс or from the underlying maternal condition.
Females And Males Of Reproductive Potential ContraceptionTo avoid exposure to the fetus, women of reproductive potential should use effective contraception during treatment and for 3 months after cessation of Дарзалекс treatment.
Pediatric UseSafety and effectiveness of Дарзалекс in pediatric patients have not been established.
Geriatric UseOf the 1166 patients that received Дарзалекс at the recommended dose, 46% were 65 to 75 years of age, and 15% were 75 years of age or older. No overall differences in safety or effectiveness were observed between these patients and younger patients.

Infusion Rates And Management Of Infusion ReactionsAdminister Дарзалекс infusion intravenously at the infusion rate described below in Table 4. Consider incremental escalation of the infusion rate only in the absence of infusion reactions.
Table 4: Infusion rates for Дарзалекс administration
Dilution volume | Initial rate (first hour) | Rate incrementa | Maximum rate | |
First infusion | 1000 mL | 50 mL/hour | 50 mL/hour every hour | 200 mL/hour |
Second infusionb | 500 mL | 50 mL/hour | 50 mL/hour every hour | 200 mL/hour |
Subsequent infusionsc | 500 mL | 100 mL/hour | 50 mL/hour every hour | 200 mL/hour |
a Consider incremental escalation of the infusion rate only in the absence of infusion reactions. b Use a dilution volume of 500 mL only if there were no infusion reactions during the first 3 hours of the first infusion. Otherwise, continue to use a dilution volume of 1000 mL and instructions for the first infusion. c Use a modified initial rate for subsequent infusions (i.e. third infusion onwards) only if there were no infusion reactions during a final infusion rate of ≥100 mL/hr in the first two infusions. Otherwise, continue to use instructions for the second infusion. |
For infusion reactions of any grade/severity, immediately interrupt the Дарзалекс infusion and manage symptoms. Management of infusion reactions may further require reduction in the rate of infusion, or treatment discontinuation of Дарзалекс as outlined below.
Administer the following pre-infusion medications to reduce the risk of infusion reactions to all patients 1-3 hours prior to every infusion of Дарзалекс:
Monotherapy:
Methylprednisolone 100 mg, or equivalent, administered intravenously. Following the second infusion, the dose of corticosteroid may be reduced (oral or intravenous methylprednisolone 60 mg).
Combination therapy:
Administer 20 mg dexamethasone (or equivalent) prior to every Дарзалекс infusion [Clinical Studies].
Dexamethasone is given intravenously prior to the first Дарзалекс infusion and oral administration may be considered prior to subsequent infusions. Additional background regimen-specific corticosteroids (e.g. prednisone) should not be taken on Дарзалекс infusion days when patients receive dexamethasone (or equivalent) as a pre-medication.
Administer post-infusion medication to reduce the risk of delayed infusion reactions to all patients 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 Дарзалекс infusions (beginning the day after the infusion).
Combination therapy:
Consider administering low-dose oral methylprednisolone (≤ 20 mg) or equivalent, the day after the Дарзалекс infusion.
However, if a background regimen-specific corticosteroid (e.g. dexamethasone, prednisone) is administered the day after the Дарзалекс infusion, additional post-infusion medications may not be needed.
In addition, for any patients with a history of chronic obstructive pulmonary disease, 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 ReactivationInitiate antiviral prophylaxis to prevent herpes zoster reactivation within 1 week after starting Дарзалекс and continue for 3 months following treatment.
Dose Modifications?No dose reductions of Дарзалекс are recommended. Dose delay may be required to allow recovery of blood cell counts in the event of hematological toxicity. For information concerning drugs given in combination with Дарзалекс, see manufacturer’s prescribing information.
Preparation For AdministrationДарзалекс is for single use only.
Prepare the solution for infusion using aseptic technique as follows:
