Pomalidomide

Bristol Myers Squibb (NYSE: BMY) reported that mezigdomide, its oral cereblon E3 ligase modulator (CELMoD), cut the risk of disease progression or death by 52% versus carfilzomib and dexamethasone alone in relapsed or refractory multiple myeloma, delivering the first Phase III readout for any CELMoD agent and handing BMS a potential new commercial pillar as its immunomodulatory drug franchise faces generic erosion from lenalidomide biosimilars. The data were the subject of a late-breaking oral presentation at the 2026 American Society of Clinical Oncology (ASCO) summit meeting. The SUCCESSOR-2 trial is a seamless Phase II/III, multicenter, randomized, open-label study that enrolled 479 patients with relapsed or refractory multiple myeloma, randomized to mezigdomide plus carfilzomib and dexamethasone (MeziKd, n\=288) or carfilzomib and dexamethasone alone (Kd, n\=191). The population was heavily pretreated and largely refractory to current standards: 92.1% were triple-class-exposed, 85.8% were refractory to an anti-CD38 monoclonal antibody, and 75.8% were refractory to lenalidomide — the very drug class from which mezigdomide descends. The primary endpoint was met decisively. Median progression-free survival reached 18 months with MeziKd versus 8.3 months with Kd (HR: 0.48; 95% CI reported; p \< 0.0001), a hazard ratio that corresponds to a 52% reduction in the risk of progression or death at a median follow-up of 10.6 months. Overall response rate was 80.2% with MeziKd versus 53.4% with Kd, and complete response or better was achieved in 26.7% versus 8.9%. Median overall survival had not yet been reached in either arm. The results were presented as a late-breaking oral at Bristol Myers Squibb ASCO 2026 (#LBA7506). The safety profile carries a meaningful hematologic burden. Grade 3–4 treatment-emergent adverse events occurred in 83.7% of MeziKd patients versus 56.5% on Kd. Neutropenia was the dominant toxicity, appearing in 61.1% of the MeziKd arm versus 9.1% on Kd, and Grade 3–4 infections occurred in 34.0% versus 15.6%. BMS described the profile as consistent with mezigdomide’s known safety profile, and notably 52.4% of MeziKd patients remained on treatment at data cutoff versus 31.4% on Kd, suggesting tolerability sufficient for continued dosing in a substantial proportion of patients. Competitive context and outlook The SUCCESSOR-2 trial results arrive at a moment when the relapsed refractory multiple myeloma treatment landscape is undergoing rapid reorganization. Bispecific T-cell engagers — including Janssen’s Tecvayli (teclistamab), Janssen’s Talvey (talquetamab), and Pfizer’s Elrexfio (elranatamab) — have reshaped late-line practice since 2023, while the CAR-T therapies Janssen and Legend Biotech’s Carvykti (ciltacabtagene autoleucel) and BMS’s own Abecma (idecabtagene vicleucel) have moved into earlier relapse settings following label expansions in 2024. Against this backdrop, mezigdomide’s oral administration, outpatient delivery, and activity in a predominantly anti-CD38-refractory and lenalidomide-refractory population position it as a chemotherapy-free oral option that does not require the manufacturing lead times of CAR-T or the step-up hospitalization protocols associated with bispecifics. CELMoD therapy in RRMM builds on the mechanistic foundation established by lenalidomide and pomalidomide but with substantially greater potency. Mezigdomide is optimized for maximal and rapid degradation of Ikaros and Aiolos transcription factors, proteins essential for myeloma cell survival, and preclinical data suggest it also reinvigorates exhausted T cells — a property that may become clinically relevant as the field increasingly uses it alongside immunotherapy backbones. The carfilzomib and dexamethasone combination was a deliberate design choice: Kd is an established standard of care in second- and third-line RRMM, making it a credible comparator and the PFS improvement over it directly interpretable for practicing oncologists. Cross-trial comparisons are limited by differences in patient populations, prior therapy exposure, and follow-up duration, but the 18-month median PFS in a population that was more than 85% anti-CD38-refractory compares favorably to historical benchmarks for pomalidomide-based triplets in similar settings. The ORR of 80.2% and the complete response rate of 26.7% are also notable in a population where most patients had already received two or more prior lines including an IMiD and an anti-CD38 antibody. BMS has indicated it will share the SUCCESSOR-2 data with health authorities, and a regulatory submission appears imminent. A second ongoing Phase III trial, SUCCESSOR-1, is evaluating mezigdomide in a separate RRMM combination, broadening the potential label scope. The company has framed mezigdomide as the centerpiece of its next-generation targeted protein degradation platform, which also encompasses ligand-directed degraders and degrader antibody conjugates — modalities that have not yet generated pivotal data but represent BMS’s long-term bet on cereblon biology beyond the IMiD era. For BMS, the commercial stakes are substantial. Revlimid (lenalidomide) generic entry has been eroding one of the company’s most durable revenue streams, and pomalidomide faces its own competitive pressure from bispecifics in later lines. Mezigdomide, if approved, would enter a market where oral convenience, outpatient administration, and activity in anti-CD38-refractory disease are genuine differentiators — though the neutropenia rate will require careful management and may limit use in older or frailer patients without growth factor support. The next milestone is a regulatory filing, with the timeline to be confirmed following health authority discussions. Your email address will not be published.

Building on the recent approval of Johnson & Johnson's TECVAYLI® plus DARZALEX FASPRO®, MajesTEC-9 is the second positive Phase 3 study to reinforce the strength of TECVAYLI® as early as second line TECVAYLI® delivered deep and durable responses with nearly two-thirds of patients achieving a complete response or better CHICAGO, May 29, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ), a worldwide leader in multiple myeloma therapies, today announced new data from the Phase 3 MajesTEC-9 study demonstrating clinically meaningful and statistically significant improvements in progression-free survival (PFS) and overall survival (OS) with TECVAYLI® (teclistamab-cqyv) versus standard of care regimens in patients with relapsed or refractory multiple myeloma treated as early as second line. In a patient population whose myeloma was predominantly refractory to anti-CD38 therapy and lenalidomide, TECVAYLI® reduced the risk of disease progression or death by 71% and the risk of death by 40%.1 These data (Abstract #7507) will be presented as an oral session today at the annual American Society of Clinical Oncology (ASCO) Annual Meeting, with simultaneous publication in The New England Journal of Medicine. Expert and company perspectives support the strength of TECVAYLI® "These findings further reinforce TECVAYLI's potential to meaningfully improve survival outcomes for patients with multiple myeloma in earlier lines," said Roberto Mina, M.D., Associate Professor, Winship Cancer Institute of Emory University.* "These results will continue to transform the role of bispecifics in clinical decision-making as early as first relapse—offering a steroid-sparing, community-based therapy for patients across all practice settings, regardless of prior anti-CD38 exposure." "After the recent approval of TECVAYLI plus DARZALEX FASPRO, a potential new standard of care, these results add to the growing body of evidence reinforcing the clinical power of TECVAYLI earlier in the treatment paradigm," said Yusri Elsayed, M.D., M.H.Sc., Ph.D., Global Therapeutic Area Head, Oncology, Johnson & Johnson. "These findings further demonstrate how we're leading in multiple myeloma as we bring new options to better match the right therapy to the right patient at each stage of disease." MajesTEC-9 study results The MajesTEC-9 study evaluated TECVAYLI®, a bispecific T-cell engager antibody therapy, versus the standard of care of pomalidomide, bortezomib, and dexamethasone (PVd) or carfilzomib and dexamethasone (Kd) in patients with relapsed/refractory multiple myeloma who have received 1 to 3 prior lines of therapy, including lenalidomide and a CD38 monoclonal antibody.1 Efficacy benefits were observed in a heavily pre-treated population, including patients predominantly refractory to anti-CD38 monoclonal antibodies (85%) and lenalidomide (79%), and more than 90% of patients who were refractory to their last line of therapy.1 Treatment with TECVAYLI® demonstrated a 71% reduction in the risk of disease progression or death (hazard ratio [HR]=0.29; 95% confidence interval [CI], 0.23, 0.38) and a 40% reduction in the risk of death (HR=0.60; 95% CI, 0.43, 0.83)] compared to standard of care, demonstrating significant improvements in both PFS and OS.1 Additionally, all key secondary endpoints showed significant improvement with TECVAYLI® versus standard of care, including nearly two-thirds of patients achieving a complete response or better (≥CR; 65.9% vs. 16.8%).1 The overall safety profile for TECVAYLI® in the study was consistent with its known safety profile. TECVAYLI® had similar rates of treatment-emergent adverse events (TEAEs) compared to standard of care (99.7% vs. 97.9%).1 Grade 3/4 TEAEs were reported by 84.9% of patients treated with TECVAYLI®, compared with 76.3% of patients receiving standard of care.1 Grade 5 TEAEs were uncommon across the two treatment groups (6.5% vs. 3.5%).1 The majority of Grade 5 TEAEs in both groups were due to infections (5.5% vs. 2.8%) and most occurred within the first six months of treatment initiation.1 Infections were more frequent with TECVAYLI® compared to standard of care (Grade 3/4, 41.6% vs. 29.0%); However, rates of Grade 3 or higher infections declined over time with disease control.1 Cytokine release syndrome occurred in 66.0% of patients treated with TECVAYLI®, mostly Grade 1 and managed with standard mitigation strategies.1 All events resolved and none led to treatment discontinuation.1 Immune effector cell-associated neurotoxicity syndrome was infrequent, occurring in 4.1% of patients and primarily Grade 1/2.1 Median duration of treatment on TECVAYLI® was almost two times longer than standard of care (13.1 vs 7.0 months).1 Regulatory review and next steps Based on these results, Johnson & Johnson is working with regulatory bodies globally to consider TECVAYLI® as early as second line. Applications for regulatory approval have been submitted to the U.S. Food and Drug Administration and the European Medicines Agency (EMA). About the MajesTEC – 9 Study MajesTEC-9 (NCT05572515) is an ongoing, randomized Phase 3 study comparing teclistamab monotherapy with pomalidomide, bortezomib and dexamethasone (PVd) or carfilzomib and dexamethasone (Kd) in patients with RRMM who have received 1–3 prior lines including lenalidomide and CD38 monoclonal antibody. The primary endpoint is PFS; secondary endpoints include complete response or better (≥CR), duration of response (DoR), time to next treatment (TTNT), progression-free survival on next line of therapy (PFS2), overall survival (OS), safety, and patient-reported outcomes. About Multiple Myeloma Multiple myeloma is a complex blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.2 In multiple myeloma, these plasma cells proliferate and spread rapidly and replace normal cells in the bone marrow with tumors.3 Multiple myeloma is the third most common blood cancer worldwide.4 More than 180,000 new cases of multiple myeloma are diagnosed globally each year.5 People living with multiple myeloma have a 5-year survival rate of 59.8 percent.6 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.7,8 In recent years, overall survival has improved from years to decades, with effective treatment options now available across every stage and line of therapy.9 About TECVAYLI® TECVAYLI® (teclistamab-cqyv) is a first-in-class, bispecific T-cell engager antibody therapy that uses innovative science to activate the immune system by binding to the CD3 receptor expressed on the surface of T-cells and to the B-cell maturation antigen (BCMA) expressed on the surface of multiple myeloma cells and some healthy B-lineage cells. TECVAYLI® received accelerated approval from the U.S. Food and Drug Administration (FDA) in October 2022 as an off-the-shelf (or ready-to-use) antibody that is administered as a subcutaneous treatment for adult patients with relapsed or refractory multiple myeloma (RRMM) who received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody.10 In February 2024, the U.S. FDA approved the supplemental Biologics License Application (sBLA) for TECVAYLI® for a reduced dosing frequency of 1.5 mg/kg every two weeks in patients with RRMM who achieved and maintained a complete response (CR) or better for a minimum of six months. In March 2026, the U.S. FDA approved TECVAYLI® in combination with DARZALEX FASPRO® (daratumumab and hyaluronidase-fihj) for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent. The supplemental Biologics License Application was proactively selected for the Commissioner's National Priority Voucher Pilot Program and also granted the application Breakthrough Therapy Designation and Real-Time Oncology Review. This approval expanded the use of TECVAYLI® into earlier lines of therapy and is the first bispecific antibody-based combination regimen in this setting. To date, more than 26,000 patients have been treated worldwide with TECVAYLI®. The European Commission (EC) granted TECVAYLI® conditional marketing authorization in August 2022 as monotherapy for the treatment of adult patients with RRMM who have received at least three prior therapies, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody, and have demonstrated disease progression since the last therapy. In August 2023, the EC approved a Type II variation application for TECVAYLI®, providing the option for a reduced dosing frequency of 1.5 mg/kg every two weeks (Q2W) in patients who have achieved a complete response or better for a minimum of six months.

TECVAYLI® INDICATIONS AND IMPORTANT SAFETY INFORMATION INDICATIONS AND USAGE TECVAYLI® (teclistamab-cqyv) is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager indicated for the treatment of adult patients with relapsed or refractory multiple myeloma: in combination with daratumumab and hyaluronidase-fihj in patients who have received at least one prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent. as monotherapy, in patients who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 monoclonal antibody. IMPORTANT SAFETY INFORMATION 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. In MajesTEC-3 (N=283), in patients who received TECVAYLI in combination with daratumumab and hyaluronidase-fihj at the recommended dosage, serious infections, including opportunistic infections, occurred in 54% of patients, Grade 3 or Grade 4 infections in 54% of patients, and fatal infections in 4.6% of patients. Monitor patients for signs and symptoms of infection prior to and during treatment with TECVAYLI and treat appropriately. Administer prophylactic antimicrobials according to current practice guidelines. Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity. Monitor immunoglobulin levels prior to and during treatment with TECVAYLI and administer subcutaneous or intravenous immunoglobulin (IVIG) to maintain the serum levels >400 mg/dL. Neutropenia - TECVAYLI can cause neutropenia and febrile neutropenia. In patients who received TECVAYLI at the recommended dose in the clinical trials (monotherapy and combination therapy trials; N=448), decreased neutrophils occurred in 88% of patients, with Grade 3 or 4 decreased neutrophils in 70%. Febrile neutropenia occurred in 6% of patients. Monitor complete blood cell counts at baseline and periodically during treatment and provide supportive care per local institutional guidelines. Monitor patients with neutropenia for signs of infection. Withhold TECVAYLI based on severity. Hypersensitivity and Other Administration Reactions - TECVAYLI can cause both systemic administration-related and local injection-site reactions. Systemic Reactions - In patients who received the recommended TECVAYLI dosage in the clinical trials (monotherapy and combination therapy trials; N=448), 2.5% of patients experienced systemic-administration reactions, which included recurrent pyrexia and rash. Local Reactions - In patients who received TECVAYLI at the recommended dosage in the clinical trials (monotherapy and combination therapy trials; N=448), injection-site reactions occurred in 37% of patients, with Grade 1 injection-site reactions in 29% and Grade 2 in 9%. Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity. Embryo-Fetal Toxicity - Based on its mechanism of action, TECVAYLI may cause fetal harm when administered to a pregnant patient. Advise pregnant patients of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with TECVAYLI and for 5 months after the last dose. ADVERSE REACTIONS The most common adverse reactions (≥20%) in patients who received TECVAYLI monotherapy were pyrexia, CRS, musculoskeletal pain, injection site reaction, fatigue, upper respiratory tract infection, nausea, headache, pneumonia, and diarrhea. The most common adverse reactions (≥20%) in patients who received TECVAYLI in combination with daratumumab and hyaluronidase-fihj were hypogammaglobulinemia, upper respiratory tract infection, CRS, cough, diarrhea, musculoskeletal pain, COVID-19, pneumonia, injection site reaction, fatigue, pyrexia, headache, nausea, gastroenteritis, and weight decreased. The most common Grade 3 to 4 laboratory abnormalities (≥20%) with TECVAYLI (as monotherapy or in combination with daratumumab and hyaluronidase-fihj) were decreased lymphocytes, decreased neutrophils, decreased white blood cells, decreased hemoglobin, and decreased platelets.

DARZALEX FASPRO® INDICATIONS AND IMPORTANT SAFETY INFORMATION INDICATIONS DARZALEX FASPRO® (daratumumab and hyaluronidase-fihj) is indicated for the treatment of adult patients with multiple myeloma: In combination with bortezomib, lenalidomide, and dexamethasone for induction and consolidation in newly diagnosed patients who are eligible for autologous stem cell transplant In combination with bortezomib, melphalan, and prednisone in newly diagnosed patients who are ineligible for autologous stem cell transplant In combination with lenalidomide and dexamethasone in newly diagnosed patients who are ineligible for autologous stem cell transplant and in patients with relapsed or refractory multiple myeloma who have received at least one prior therapy In combination with bortezomib, thalidomide, and dexamethasone in newly diagnosed patients who are eligible for autologous stem cell transplant In combination with pomalidomide and dexamethasone in patients who have received at least one prior line of therapy including lenalidomide and a proteasome inhibitor (PI) In combination with carfilzomib and dexamethasone in patients with relapsed or refractory multiple myeloma who have received one to three prior lines of therapy In combination with bortezomib and dexamethasone in patients who have received at least one prior therapy As monotherapy in patients who have received at least three prior lines of therapy including a PI and an immunomodulatory agent or who are double refractory to a PI and an immunomodulatory agent DARZALEX FASPRO® as monotherapy is indicated for the treatment of adult patients with high-risk smoldering multiple myeloma. IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS DARZALEX FASPRO® is contraindicated in patients with a history of severe hypersensitivity to daratumumab, hyaluronidase, or any of the components of the formulation. 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 in combination, 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 reaction 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, insomnia, headache, rash, pyrexia, cough, muscle spasms, back pain, vomiting, hypertension, musculoskeletal pain, upper respiratory tract infection, , peripheral neuropathy, peripheral sensory neuropathy, constipation, pneumonia, edema, peripheral edema, and anemia. 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.

DARZALEX® INDICATIONS AND IMPORTANT SAFETY INFORMATION INDICATIONS DARZALEX® (daratumumab) is indicated for the treatment of adult patients with multiple myeloma: In combination with bortezomib, melphalan, and prednisone in newly diagnosed patients who are ineligible for autologous stem cell transplant In combination with lenalidomide and dexamethasone in newly diagnosed patients who are ineligible for autologous stem cell transplant and in patients with relapsed or refractory multiple myeloma who have received at least one prior therapy In combination with bortezomib, thalidomide, and dexamethasone in newly diagnosed patients who are eligible for autologous stem cell transplant In combination with pomalidomide and dexamethasone in patients who have received at least one prior line of therapy including lenalidomide and a proteasome inhibitor In combination with carfilzomib and dexamethasone in patients with relapsed or refractory multiple myeloma who have received one to three prior lines of therapy In combination with bortezomib and dexamethasone in patients who have received at least one prior therapy As monotherapy in patients 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 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.
