Johnson & Johnson Announces U.S. FDA Approval of TECVAYLI® plus DARZALEX FASPRO® for Relapsed/Refractory Multiple Myeloma, Offering a Potential New Standard of Care as Early as Second Line

Approval based on unprecedented Phase 3 data demonstrating statistically significant improvements in progression–free survival and overall survival versus standard of care regimens

83.3% of patients were alive at three years, indicating durable clinical benefit

HORSHAM, Pa., March 5, 2026 /PRNewswire/ — Johnson & Johnson (NYSE:JNJ), a worldwide leader in multiple myeloma therapies, today announced that the U.S. Food and Drug Administration (FDA) approved TECVAYLI^® (teclistamab-cqyv) plus DARZALEX FASPRO^® (daratumumab and hyaluronidase-fihj) for the treatment of adults with relapsed or refractory multiple myeloma (RRMM) who have received at least one prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent.¹ TECVAYLI^® and DARZALEX FASPRO^® work synergistically to prime and activate the immune system to eradicate myeloma cells that express the BCMA protein.¹ This approval offers a potential new standard of care (SOC) as early as second line and brings a novel treatment approach for the 40% of patients with multiple myeloma who experience disease relapse.²

TECVAYLI® in combination with DARZALEX FASPRO® demonstrated statistically significant improvements in PFS in patients with RRMM compared to standard treatment after a median follow-up of three years in patients with RRMM. The results were presented in December 2025 as a late-breaking oral presentation at the American Society of Hematology (ASH) Annual Meeting with simultaneous publication in The New England Journal of Medicine.

Perspectives on Expanding Multiple Myeloma Treatment Options

“This new treatment option can redefine how we approach RRMM treatment by giving healthcare providers a regimen with improvement in PFS and OS and a well-characterized safety profile,” said Dr. Luciano J. Costa, Professor of Multiple Myeloma and Director of the Multiple Myeloma Research and Treatment Program at the University of Alabama at Birmingham, and Primary Investigator of MajesTEC-3*. “The option to use this regimen as early as second line is particularly important because patients with RRMM often experience multiple relapses and reduced responsiveness to therapy over time, which makes earlier treatment with the most effective therapies critical. In addition, the steroid-sparing approach may reduce toxicity and improve tolerability.”

“There is a critical need to expand community-based treatment options for multiple myeloma patients, allowing them to receive care closer to home while respecting their individual treatment preferences,” said Heather Ortner Cooper, President & CEO of the International Myeloma Foundation**. “This approval enhances the therapeutic landscape, giving oncologists diverse options to personalize treatment plans for each patient.”

“As the leader in hematology, we have a proud history of transforming the treatment landscape for multiple myeloma. This approval represents another pivotal milestone in improving outcomes for patients living with this disease, with a unique regimen accessible to patients across all practice settings,” said Imran Khan, M.D., Ph.D., Vice President, U.S. Hematology Medical Affairs, Johnson & Johnson. “The FDA approval of TECVAYLI plus DARZALEX FASPRO adds a powerful new treatment option to our multiple myeloma portfolio, moving us closer to our ambition of one day curing this disease.”

Unprecedented MajesTEC-3 Study Results

The approval is based on data from the Phase 3 MajesTEC-3 study, an ongoing, Phase 3 randomized study evaluating the safety and efficacy of teclistamab plus daratumumab versus investigator’s choice of daratumumab and dexamethasone with either pomalidomide or bortezomib in patients with RRMM who have received at least one prior line of therapy. TECVAYLI^® in combination with DARZALEX FASPRO^® demonstrated statistically significant improvements in PFS and OS in patients with RRMM compared to standard treatment after a median follow-up of three years in patients with RRMM. Results show an 83% reduction in the risk of disease progression or death compared to standard regimens (hazard ratio [HR], 0.17; 95 percent confidence interval [CI], 0.12-0.23; P<0.0001).³ The three-year PFS rate was 83% compared to 30% in the control arm, underscoring a durable benefit.³ The results were presented in December 2025 as a late-breaking oral presentation at the American Society of Hematology (ASH) Annual Meeting with simultaneous publication in The New England Journal of Medicine.

Significant improvements compared to SOC were observed across key secondary endpoints, including treatment response rates, minimal residual disease (MRD)-negativity, OS, and time to worsening of symptoms – revealing the impact of the regimen across varied patient measures.³ TECVAYLI^® plus DARZALEX FASPRO^® showed higher rates of overall response (ORR) (89.0% vs. 75.3%; OR, 2.65; 95% CI, 1.68-4.18), complete response (≥CR) (81.8% vs. 32.1%; odds ratio [OR], 9.56; 95% CI, 6.47-14.14), and MRD-negativity (58.4% vs. 17.1%; OR, 6.78; 95% CI, 4.53-10.15, P<0.0001; evaluable rate of 89.3% vs. 63.0%) at three-years follow-up.³ OS favored TECVAYLI^® plus DARZALEX FASPRO^®(HR, 0.46; 95% CI, 0.32-0.65; P<0.0001) across all prespecified subgroups. At three years, OS rates were 83.3% and 65.0% for the TECVAYLI^® plus DARZALEX FASPRO^® arm and the control arm, respectively.³

In the MajesTEC-3 study, TECVAYLI^® plus DARZALEX FASPRO^® and SOC comparators had similar rates of Grade 3/4 (95.1% vs. 96.6%) treatment-emergent adverse events (TEAE).³ Most Grade 3/4 events were due to cytopenias and infection.³ Infections were observed with TECVAYLI^® and DARZALEX FASPRO^® (any grade, 96.5%; Grade 3/4, 54.1%) and DPd/DVd control (any grade 84.1%; Grade 3/4 43.4%). Grade 3 or higher infections with TECVAYLI^® and DARZALEX FASPRO^® declined after the first 6 months of treatment consistent with use of established immunoglobulin supplementation and infection prophylaxis protocols, along with switch to monthly dosing.³ Cytokine release syndrome occurred in 60.1% of patients; all cases were Grade 1/2, did not lead to treatment discontinuation and were effectively managed using standard guidelines.³ Immune effector cell-associated neurotoxicity syndrome was rare and occurred in 1.1% of patients.³ Serious adverse events occurred in 70.7% of patients compared to 62.4% of patients treated with the control regimen, while treatment discontinuations due to adverse events were low (4.6% vs. 5.5%).³ Grade 5 TEAEs were 7.1% and 5.9% with TECVAYLI^® plus DARZALEX FASPRO^® and DPd/DVd control, respectively.³

The FDA proactively selected the teclistamab MajesTEC-3 supplemental Biologics License Application (sBLA) to participate in the Commissioner’s National Priority Voucher (CNPV) Pilot Program as it aligns with the program’s priority to deliver more innovative therapies for American people. The FDA also granted the application Breakthrough Therapy Designation and Real-Time Oncology Review.

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.⁸In multiple myeloma, these plasma cells proliferate and spread rapidly and replace normal cells in the bone marrow with tumors.⁹ Multiple myeloma is the third most common blood cancer worldwide and remains an incurable disease.¹⁰ In 2024, it was estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 people would die from the disease.¹¹People living with multiple myeloma have a 5-year survival rate of 59.8 percent.¹² While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels and kidney problems or infections.^13,14

IMPORTANT SAFETY INFORMATION

WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITY including IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME

Cytokine release syndrome (CRS), including life-threatening or fatal reactions, can occur in patients receiving TECVAYLI. Initiate treatment with TECVAYLI step-up dosing schedule to reduce risk of CRS. Withhold TECVAYLI until CRS resolves or permanently discontinue based on severity.

Neurologic toxicity, including Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) and serious, life-threatening, or fatal reactions, can occur in patients receiving TECVAYLI. Monitor patients for signs or symptoms of neurologic toxicity, including ICANS, during treatment. Withhold TECVAYLI until neurologic toxicity resolves or permanently discontinue based on severity.

TECVAYLI is available only through a restricted program called the TECVAYLI and TALVEY^® Risk Evaluation and Mitigation Strategy (REMS).

WARNINGS AND PRECAUTIONS

Cytokine Release Syndrome – TECVAYLI can cause cytokine release syndrome (CRS), including life-threatening or fatal reactions.

In the clinical trials (monotherapy and combination therapy; N=448), CRS occurred in 64% of patients who received TECVAYLI at the recommended dose, with Grade 1 CRS occurring in 46% of patients, Grade 2 in 18%, and Grade 3 in 0.2%. Recurrent CRS occurred in 27% of patients. Most patients experienced CRS during the initial step-up dosing schedule (step-up dose 1 [37%], step-up dose 2 [32%], or the initial treatment dose [20%]). CRS first occurred following subsequent doses of TECVAYLI in 2.5% of patients. The median time to onset of CRS was 2 (range: 1 to 9) days after the most recent dose and the median duration of CRS was 2 (range: 1 to 22) days.

Clinical signs and symptoms of CRS included, but were not limited to, fever, hypoxia, chills, hypotension, sinus tachycardia, headache, and elevated liver enzymes (aspartate aminotransferase and alanine aminotransferase elevation).

Initiate therapy according to TECVAYLI step-up dosing schedule to reduce risk of CRS. Administer pretreatment medications to reduce risk of CRS and monitor patients following administration of TECVAYLI accordingly.

At the first sign of CRS, immediately evaluate patient for hospitalization. Administer supportive care based on severity and consider further management per current practice guidelines. Withhold until CRS resolves or permanently discontinue TECVAYLI based on severity.

TECVAYLI is available only through a restricted program under a REMS.

Neurologic Toxicity including Immune Effector Cell-Associated Neurotoxicity Syndrome – TECVAYLI can cause serious, life-threatening, or fatal neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS).

In the clinical trials (monotherapy and combination therapy trials; N=448), neurologic toxicity occurred in 60% of patients who received TECVAYLI at the recommended dosage, with Grade 3 or 4 neurologic toxicity in 6%. Neurologic toxicities reported in ≥5% of patients included headache (27%), sensory neuropathy (16%), motor dysfunction (15%), insomnia (12%), encephalopathy (11%), and dizziness (8%). Fatal neurologic toxicity occurred in 0.4% of patients, including Guillain-Barré syndrome and status epilepticus (one patient each).

In MajesTEC-1, ICANS was reported in 6% of patients who received TECVAYLI as monotherapy at the recommended dosage. Recurrent ICANS occurred in 1.8% of patients. Most patients experienced ICANS following step-up dose 1 (1.2%), step-up dose 2 (0.6%), or the initial treatment dose (1.8%). Less than 3% of patients developed first occurrence of ICANS following subsequent TECVAYLI doses. The median time to onset of ICANS was 4 (range: 2 to 8) days after the most recent dose with a median duration of 3 (range: 1 to 20) days. The most frequent clinical manifestations of ICANS reported were confusional state and dysgraphia.

In MajesTEC-3, ICANS was reported in 1.1% of patients who received the recommended TECVAYLI dosage in combination with daratumumab and hyaluronidase-fihj, including Grade 4 ICANS in 1 patient. All events of ICANS occurred during the step-up dosing schedule. The median time to onset of ICANS was 2 (range: 1 to 3) days after the most recent dose and the median duration of ICANS was 2 (range: 1 to 2) days. The clinical manifestations of ICANS reported were amnesia, encephalopathy and delirium.

The onset of ICANS can be concurrent with CRS, following resolution of CRS, or in the absence of CRS.

Monitor patients for signs and symptoms of neurologic toxicity, including ICANS during TECVAYLI treatment. At the first sign of neurologic toxicity, including ICANS, immediately evaluate patient and provide supportive therapy based on severity. Withhold until neurologic toxicity resolves or permanently discontinue TECVAYLI based on severity per recommendations and consider further management per current practice guidelines.

Due to the potential for neurologic toxicity, patients receiving TECVAYLI are at risk of depressed level of consciousness. Advise patients to refrain from driving or operating heavy or potentially dangerous machinery during and for 48 hours after completion of TECVAYLI step-up dosing schedule and in the event of new onset of any neurologic toxicity symptoms until neurologic toxicity resolves.

TECVAYLI is available only through a restricted program under a REMS.

TECVAYLI and TALVEY REMS – TECVAYLI is available only through a restricted program under a REMS called the TECVAYLI and TALVEY REMS because of the risks of CRS and neurologic toxicity, including ICANS.

Hepatotoxicity – TECVAYLI can cause hepatotoxicity, including fatalities. There was one fatal case of hepatic failure in MajesTEC-1. In patients who received TECVAYLI at the recommended dose in the clinical trials (monotherapy and combination therapy trials; N=448) elevated aspartate aminotransferase (AST) occurred in 47% of patients, with Grade 3 or 4 elevations in 2.9%. Elevated alanine aminotransferase (ALT) occurred in 48% of patients, with Grade 3 or 4 elevations in 3.8%. Elevated total bilirubin occurred in 10% of patients with Grade 3 or 4 elevations in 0.7%. Liver enzyme elevation can occur with or without concurrent CRS.

Monitor liver enzymes and bilirubin at baseline and during treatment as clinically indicated. Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity.

Infections – TECVAYLI can cause severe, life-threatening, or fatal infections.

In MajesTEC-1 (N=165), in patients who received the recommended TECVAYLI dosage, serious infections, including opportunistic infections, occurred in 30% of patients, Grade 3 or 4 infections in 35% of patients, and fatal infections in 4.2% of patients.

WARNINGS AND PRECAUTIONS

Hypersensitivity and Other Administration Reactions
Both systemic administration-related reactions, including severe or life-threatening reactions, and local injection-site reactions can occur with DARZALEX FASPRO^®. Fatal reactions have been reported with daratumumab-containing products, including DARZALEX FASPRO^®.

Systemic Reactions
In a pooled safety population of 1446 patients with multiple myeloma (N=1235) or light chain (AL) amyloidosis (N=193) who received DARZALEX FASPRO^® as monotherapy or as part of a combination therapy, 7% of patients experienced a systemic administration-related reaction (Grade 2: 3%, Grade 3: 0.8%, Grade 4: 0.1%). In patients with high-risk smoldering multiple myeloma (N=193), systemic administration-related reactions occurred in 17% of patients in AQUILA (Grade 2: 7%, Grade 3: 1%).

In all patients (N=1639), systemic administration-related reactions occurred in 7% of patients with the first injection, 0.5% with the second injection, and cumulatively 1% with subsequent injections. The median time to onset was 3.2 hours (range: 4 minutes to 3.5 days). Of the 283 systemic administration-related reactions that occurred in 135 patients, 240 (85%) occurred on the day of DARZALEX FASPRO^® administration. Delayed systemic administration-related reactions have occurred in 1% of the patients.

Severe reactions included hypoxia, dyspnea, hypertension, tachycardia, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Other signs and symptoms of systemic administration-related reactions may include respiratory symptoms, such as bronchospasm, nasal congestion, cough, throat irritation, allergic rhinitis, and wheezing, as well as anaphylactic reaction, pyrexia, chest pain, pruritus, chills, vomiting, nausea, hypotension, and blurred vision.

Pre-medicate patients with histamine-1 receptor antagonist, acetaminophen, and corticosteroids. Monitor patients for systemic administration-related reactions, especially following the first and second injections. For anaphylactic reaction or life-threatening (Grade 4) administration-related reactions, immediately and permanently discontinue DARZALEX FASPRO^®. Consider administering corticosteroids and other medications after the administration of DARZALEX FASPRO^® depending on dosing regimen and medical history to minimize the risk of delayed (defined as occurring the day after administration) systemic administration-related reactions.

Ocular adverse reactions, including acute myopia and narrowing of the anterior chamber angle due to ciliochoroidal effusions with potential for increased intraocular pressure or glaucoma, have occurred with daratumumab-containing products. If ocular symptoms occur, interrupt DARZALEX FASPRO^® and seek immediate ophthalmologic evaluation prior to restarting DARZALEX FASPRO^®.

Local Reactions
In this pooled safety population of 1446 patients with multiple myeloma (N=1253) or light chain amyloidosis (N=193), injection-site reactions occurred in 8% of patients, including Grade 2 reactions in 1.1%. The most frequent (>1%) injection-site reactions were injection site erythema and injection site rash. In patients with high-risk smoldering multiple myeloma (N=193), injection-site reactions occurred in 28% of patients, including Grade 2 reactions in 3%. These local reactions occurred a median of 6 minutes (range: 0 minutes to 6.5 days) after starting administration of DARZALEX FASPRO^®. Monitor for local reactions and consider symptomatic management.

Infections
DARZALEX FASPRO^® can cause serious, life-threatening, or fatal infections. In patients who received DARZALEX FASPRO^® in a pooled safety population including patients with smoldering multiple myeloma and light chain (AL) amyloidosis (N=1639), serious infections, including opportunistic infections, occurred in 24% of patients, Grade 3 or 4 infections occurred in 22%, and fatal infections occurred in 2.5%. The most common type of serious infection reported was pneumonia (8.5%).

Monitor patients for signs and symptoms of infection prior to and during treatment with DARZALEX FASPRO^® and treat appropriately. Administer prophylactic antimicrobials according to guidelines.

Neutropenia
Daratumumab 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. Consider withholding DARZALEX FASPRO^® until recovery of neutrophils. In lower body weight patients receiving DARZALEX FASPRO^®, higher rates of Grade 3-4 neutropenia were observed.

Thrombocytopenia
Daratumumab may increase thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. Consider withholding DARZALEX FASPRO^® until recovery of platelets.

Embryo-Fetal Toxicity
Based on the mechanism of action, DARZALEX FASPRO^® can cause fetal harm when administered to a pregnant woman. DARZALEX FASPRO^® may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX FASPRO^® and for 3 months after the last dose.

The combination of DARZALEX FASPRO^® with lenalidomide, thalidomide, or pomalidomide is contraindicated in pregnant women because lenalidomide, thalidomide, and pomalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, thalidomide, or pomalidomide prescribing information on use during pregnancy.

Interference With Serological Testing
Daratumumab 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 administration. 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 DARZALEX FASPRO^®. Type and screen patients prior to starting DARZALEX FASPRO^®.

Interference With Determination of Complete Response
Daratumumab is a human immunoglobulin G (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 DARZALEX FASPRO^®-treated patients with IgG kappa myeloma protein.

ADVERSE REACTIONS
In multiple myeloma, the most common adverse reaction (≥20%) with DARZALEX FASPRO^® monotherapy is upper respiratory tract infection. The most common adverse reactions with combination therapy (≥20% for any combination) include fatigue, nausea, diarrhea, dyspnea, sleep disorder, headache, rash, renal impairment, motor dysfunction, pyrexia, cough, muscle spasms, back pain, vomiting, hypertension, musculoskeletal pain, decreased appetite, urinary tract infection, abdominal pain, upper respiratory tract infection, peripheral neuropathy, peripheral sensory neuropathy, constipation, pneumonia, edema, dizziness, bruising, and COVID-19.

The most common adverse reactions (≥20%) in patients with high-risk smoldering multiple myeloma who received DARZALEX FASPRO^® monotherapy are upper respiratory tract infection, musculoskeletal pain, fatigue, diarrhea, rash, sleep disorder, sensory neuropathy, and injection site reactions.

The most common hematology laboratory abnormalities (≥40%) with DARZALEX FASPRO^® are decreased leukocytes, decreased lymphocytes, decreased neutrophils, decreased platelets, and decreased hemoglobin.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

DARZALEX^® is contraindicated in patients with a history of severe hypersensitivity (eg, anaphylactic reactions) to daratumumab or any of the components of the formulation.

WARNINGS AND PRECAUTIONS

Infusion-Related Reactions

DARZALEX^® can cause severe and/or serious infusion-related reactions including anaphylactic reactions. These reactions can be life threatening, and fatal outcomes have been reported. In clinical trials (monotherapy and combination: N=2066), infusion-related reactions occurred in 37% of patients with the Week 1 (16 mg/kg) infusion, 2% with the Week 2 infusion, and cumulatively 6% with subsequent infusions. Less than 1% of patients had a Grade 3/4 infusion-related reaction at Week 2 or subsequent infusions. The median time to onset was 1.5 hours (range: 0 to 73 hours). Nearly all reactions occurred during infusion or within 4 hours of completing DARZALEX^®. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, tachycardia, headache, laryngeal edema, pulmonary edema, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting, and nausea. Less common signs and symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, hypotension and blurred vision.

When DARZALEX^® dosing was interrupted in the setting of ASCT (CASSIOPEIA) for a median of 3.75 months (range: 2.4 to 6.9 months), upon re-initiation of DARZALEX^®, the incidence of infusion-related reactions was 11% for the first infusion following ASCT. Infusion-related reactions occurring at re-initiation of DARZALEX^® following ASCT were consistent in terms of symptoms and severity (Grade 3 or 4: <1%) with those reported in previous studies at Week 2 or subsequent infusions. In EQUULEUS, patients receiving combination treatment (n=97) were administered the first 16 mg/kg dose at Week 1 split over two days, ie, 8 mg/kg on Day 1 and Day 2, respectively. The incidence of any grade infusion-related reactions was 42%, with 36% of patients experiencing infusion-related reactions on Day 1 of Week 1, 4% on Day 2 of Week 1, and 8% with subsequent infusions.

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 if an anaphylactic reaction or life-threatening (Grade 4) reaction occurs and institute appropriate emergency care. 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-related reactions, administer oral corticosteroids to all patients following DARZALEX^® 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.

Ocular adverse reactions, including acute myopia and narrowing of the anterior chamber angle due to ciliochoroidal effusions with potential for increased intraocular pressure or glaucoma, have occurred with DARZALEX^® infusion. If ocular symptoms occur, interrupt DARZALEX^® infusion and seek immediate ophthalmologic evaluation prior to restarting DARZALEX^®.

Interference With Serological Testing

Daratumumab 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 is not impacted. 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^®.

Neutropenia and Thrombocytopenia

DARZALEX^® may increase neutropenia and thrombocytopenia 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. Consider withholding DARZALEX^® until recovery of neutrophils or for recovery of platelets.

Interference With Determination of Complete Response

Daratumumab is a human immunoglobulin G (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.

Embryo-Fetal Toxicity

Based on the mechanism of action, DARZALEX^® can cause fetal harm when administered to a pregnant woman. DARZALEX^® may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX^®and for 3 months after the last dose.

The combination of DARZALEX^® with lenalidomide, pomalidomide, or thalidomide is contraindicated in pregnant women because lenalidomide, pomalidomide, and thalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, pomalidomide, or thalidomide prescribing information on use during pregnancy.

ADVERSE REACTIONS

The most frequently reported adverse reactions (incidence ≥20%) were upper respiratory infection, neutropenia, infusion-related reactions, thrombocytopenia, diarrhea, constipation, anemia, peripheral sensory neuropathy, fatigue, peripheral edema, nausea, cough, pyrexia, dyspnea, and asthenia. The most common hematologic laboratory abnormalities (≥40%) with DARZALEX^® are neutropenia, lymphopenia, thrombocytopenia, leukopenia, and anemia.
