Johnson & Johnson

• Median overall survival, a secondary endpoint, reached nearly 3.5 years with Johnson & Johnson's RYBREVANT^® plus LAZCLUZE^® in atypical EGFR-mutated disease
• Consistent responses observed across atypical EGFR mutation subgroups, including those historically associated with poorer outcomes
• ASCO 2026 results reinforce the significance of RYBREVANT^®-based regimens for patients across EGFR mutations

CHICAGO, May 29, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced updated results from the Phase 1/1b CHRYSALIS-2 study evaluating intravenous RYBREVANT^® (amivantamab-vmjw) in combination with LAZCLUZE^® (lazertinib) in patients with advanced non-small cell lung cancer (NSCLC) with atypical epidermal growth factor receptor (EGFR) mutations. The analysis showed encouraging long-term outcomes with RYBREVANT^® plus LAZCLUZE^® in this difficult-to-treat population. Median overall survival, a secondary endpoint, was nearly 3.5 years.¹ The primary endpoint of objective response rate was previously reported.² These results add to the growing body of evidence demonstrating the potential of RYBREVANT^® plus LAZCLUZE^® to deliver durable survival outcomes across both common and atypical EGFR-mutated advanced NSCLC in the first-line setting. Data were presented in an oral session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract #8501).¹

Significant unmet need in patients with atypical EGFR-mutated NSCLC

Patients with atypical EGFR-mutated NSCLC tend to have poorer outcomes than those with common EGFR mutations (exon 19 deletions and L858R substitutions), and effective first-line treatment options remain limited.^3,4 These mutations represent approximately 10-20 percent of all EGFR-mutated cases.⁵ Median overall survival with current standard of care single-agent therapies remains under two years, highlighting a significant unmet need for treatments that can deliver more durable benefit in this setting.^6,7 RYBREVANT^® is designed to dual target EGFR and mesenchymal-epithelial transition (MET), while engaging the immune system.^8,9,10,11 These complementary mechanisms play a central role in tumor growth and treatment resistance and may help address the underlying drivers of disease.

Expert and company perspectives supporting the strength of RYBREVANT^® plus LAZCLUZE^®

"For patients with non-small cell lung cancer harboring atypical EGFR-mutations, first-line treatment decisions are often clouded by uncertainty regarding the efficacy of currently available EGFR tyrosine kinase inhibitors," said Joel Neal,* M.D., Ph.D., principal investigator of the Phase 1/1b CHRYSALIS-2 study. "The responses we've seen in this trial suggest the potential for more durable disease control, and the overall survival data reinforce that picture. These long-term outcomes begin to change how we think about treatment options in managing this subtype of lung cancer." Neal is also a Professor of Medicine in the Division of Oncology at Stanford Medicine.

"Disease progression and molecular resistance remain critical barriers in EGFR-mutated non-small cell lung cancer," said Yusri Elsayed, M.D., M.H.Sc., Ph.D., Global Therapeutic Area Head, Oncology, Johnson & Johnson. "RYBREVANT-based combinations demonstrate the power of changing the biology by addressing multiple disease drivers from the start rather than relying on single-pathway strategies. With strong outcomes across all known EGFR mutations, this approach is raising the bar for what first-line treatment can achieve."

Detailed CHRYSALIS-2 study results

In Cohort C of the CHRYSALIS-2 study, RYBREVANT^® plus LAZCLUZE^® was evaluated as a first-line treatment in patients with atypical EGFR-mutated advanced NSCLC, excluding EGFR exon 20 insertion mutations (n=49). The most common atypical EGFR mutations included G719X (55 percent), S768X (27 percent) and L861X (24 percent), with 35 percent of patients harboring multiple atypical mutations. The study previously reported an objective response rate of 57 percent (primary endpoint).^1,2

Median overall survival with RYBREVANT^® plus LAZCLUZE^® reached nearly 3.5 years (41.0 months; 95 percent confidence interval [CI], 27.7-not estimable) at a median follow-up of 31.3 months. Overall survival rates were 55 percent at three years and 46 percent at four years.¹

Consistent clinical activity was observed across atypical EGFR mutation subgroups, as well as across patient and disease characteristics such as central nervous system metastases and TP53 status. Patients were also able to remain on treatment long-term across mutation groups and baseline characteristics. Notably, 41 percent of patients remained on RYBREVANT^® for two years or longer, further supporting the durable survival observed with this combination.¹

The safety profile of RYBREVANT^® plus LAZCLUZE^® was consistent with previous reports, with no new safety signals observed with longer follow-up. Most adverse events were Grade 1 or 2. The most common treatment-emergent adverse events occurring in more than 30 percent of patients included paronychia (78 percent), rash (65 percent), hypoalbuminemia (61 percent) and infusion-related reactions (61 percent).¹

RYBREVANT^®-based regimens are approved for patients with EGFR-mutated advanced NSCLC across common (exon 19 deletions and exon 21 L858R substitution mutations) and exon 20 insertion mutations, including in the first-line setting.¹² These results further define long-term outcomes with first-line RYBREVANT^® plus LAZCLUZE^® for patients with atypical EGFR mutations. Additional data being presented at ASCO 2026 in lung, head and neck, and colorectal cancers underscore the broader potential of RYBREVANT^® across tumor types.

About the CHRYSALIS-2 Study

CHRYSALIS-2 (NCT04077463) is an open-label Phase 1/1b study to evaluate the safety and pharmacokinetics of LAZCLUZE^®, a third-generation EGFR-TKI, as monotherapy or in combinations with RYBREVANT^®, a human bispecific EGFR and cMet antibody in participants with advanced NSCLC. The study enrolled 460 patients with advanced NSCLC.¹³

Cohort C of the ongoing CHRYSALIS-2 study evaluates patients with atypical EGFR-mutated advanced NSCLC, excluding exon 20 insertion and classical EGFR mutations, who are treatment-naïve or have received up to two prior lines of therapy. Patients received intravenous RYBREVANT^® in combination with LAZCLUZE^® administered orally once daily.¹³

About Non-Small Cell Lung Cancer

Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases.^14,15 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.¹⁶ Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.¹⁷ EGFR mutations are present in 10 to 15 percent of Western patients with NSCLC with adenocarcinoma histology and occur in 40 to 50 percent of Asian patients.^{14,15,18,19,20,21} EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.²² The five-year survival rate for all people with advanced NSCLC and EGFR mutations treated with EGFR tyrosine kinase inhibitors (TKIs) is less than 20 percent.^23,24 EGFR exon 20 insertion mutations are the third-most prevalent activating EGFR mutation.²⁵ Patients with EGFR exon 20 insertion mutations have a real-world five-year overall survival (OS) of eight percent in the frontline setting, which is worse than patients with EGFR ex19del or L858R mutations, who have a real-world five-year OS of 19 percent.²⁶

• 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^® 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.

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^®.
