Chemotherapy-free combination regimen ushers in new era for first-line treatment, with overall survival projected to exceed four years, surpassing monotherapy TKI osimertinib by more than one year
RARITAN, N.J., Sept. 7, 2025 /PR Newswire/ – Johnson & Johnson (NYSE: JNJ) today announced The New England Journal of Medicine (NEJM) published results from the Phase 3 MARIPOSA study, which showed RYBREVANT® (amivantamab-vmjw) plus LAZCLUZE® (lazertinib) demonstrated a statistically significant and clinically meaningful overall survival (OS) improvement for patients with previously untreated (first-line) locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions (ex19del) or L858R substitution mutations.1 The article is available with free access here for a limited time.
At a median follow-up of 37.8 months, RYBREVANT® plus LAZCLUZE® showed a statistically significant reduction in the risk of death compared to osimertinib (hazard ratio [HR], 0.75; 95 percent confidence interval [CI], 0.61-0.92, P=0.005). The median OS for the combination has not yet been reached (95 percent CI, 42.9-not estimable). Median OS for the combination is projected to exceed over four years (absolute increase of over one year) compared to the median of three years observed with osimertinib.1
"This is a turning point in how we treat EGFR-mutated lung cancer," said Professor James Chih-Hsin Yang*, M.D., Ph.D., Director, National Taiwan University Cancer Center, Taipei, Taiwan, and lead author on the NEJM manuscript. "We're now seeing the potential for patients to live significantly longer than we thought possible. Starting with RYBREVANT and LAZCLUZE may prevent common types of resistance and reserves chemotherapy for later lines of therapy, which can help achieve the best possible outcomes."
Through the triple mode of action, which includes targeting EGFR mutations from two angles, blocking MET, and engaging the immune system, the combination of RYBREVANT® and LAZCLUZE® has the potential to change the natural history of the disease by reducing the spectrum and complexity of acquired resistance mechanisms.2
"We're changing the trajectory of this disease," said Joshua Bauml, M.D., Vice President, Disease Area Leader, Lung Cancer, Johnson & Johnson Innovative Medicine. "Patients with EGFR-mutated lung cancer have waited too long for meaningful progress. Now, we're delivering survival outcomes that raise expectations and redefine what first-line treatment can achieve."
The safety profile of RYBREVANT® plus LAZCLUZE® was consistent with the primary analysis and no new safety signals emerged with longer-term follow-up. Most AEs (grade 3 or higher) occurred early in treatment. RYBREVANT® studies suggest that using prophylactic measures can help lower the risk of skin reactions, infusion-related reactions and venous thromboembolic events.3,4,5
Johnson & Johnson presented the overall survival results at the European Lung Cancer Congress (ELCC) 2025 in Paris in March.
About the MARIPOSA Study
MARIPOSA (NCT04487080), which enrolled 1,074 patients, is a randomized, Phase 3 study evaluating RYBREVANT® in combination with LAZCLUZE® versus osimertinib and versus LAZCLUZE® alone in first-line treatment of patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletion (ex19del) or substitution mutations. The primary endpoint of the study is progression-free survival (PFS) (using RECIST v1.1 guidelines**) as assessed by BICR. Secondary endpoints include overall survival, overall response rate, duration or response, progression-free survival after first subsequent therapy (PFS2) and intracranial PFS.6

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.23,24 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.25 Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.26 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.23,24,27,28,29,30 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.31 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.32,33 EGFR exon 20 insertion mutations are the third most prevalent activating EGFR mutation.34 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.35
IMPORTANT SAFETY INFORMATION7,36
WARNINGS AND PRECAUTIONS
Infusion-Related Reactions
RYBREVANT® can cause infusion-related reactions (IRR) including anaphylaxis; signs and symptoms of IRR include dyspnea, flushing, fever, chills, nausea, chest discomfort, hypotension, and vomiting. The median time to IRR onset is approximately 1 hour.
RYBREVANT® with LAZCLUZE®
RYBREVANT® in combination with LAZCLUZE® can cause infusion-related reactions.

Monitor patients for signs and symptoms of infusion reactions during RYBREVANT® infusion in a setting where cardiopulmonary resuscitation medication and equipment are available. Interrupt infusion if IRR is suspected. Reduce the infusion rate or permanently discontinue RYBREVANT® based on severity. If an anaphylactic reaction occurs, permanently discontinue RYBREVANT®.

Monitor patients for new or worsening symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever). For patients receiving RYBREVANT® in combination with LAZCLUZE®, immediately withhold both drugs in patients with suspected ILD/pneumonitis and permanently discontinue if ILD/pneumonitis is confirmed. For patients receiving RYBREVANT® as a single agent or in combination with carboplatin and pemetrexed, immediately withhold RYBREVANT® in patients with suspected ILD/pneumonitis and permanently discontinue if ILD/pneumonitis is confirmed.

In MARIPOSA, VTEs occurred in 36% of patients receiving RYBREVANT® in combination with LAZCLUZE®, including Grade 3 in 10% and Grade 4 in 0.5% of patients. On-study VTEs occurred in 1.2% of patients (n=5) while receiving anticoagulation therapy. There were two fatal cases of VTE (0.5%), 9% of patients had VTE leading to dose interruptions of RYBREVANT®, and 7% of patients had VTE leading to dose interruptions of LAZCLUZE®; 1% of patients had VTE leading to dose reductions of RYBREVANT®, and 0.5% of patients had VTE leading to dose reductions of LAZCLUZE®; 3.1% of patients had VTE leading to permanent discontinuation of RYBREVANT®, and 1.9% of patients had VTE leading to permanent discontinuation of LAZCLUZE®.

Administer prophylactic anticoagulation for the first four months of treatment. The use of Vitamin K antagonists is not recommended. Monitor for signs and symptoms of VTE events and treat as medically appropriate.
Withhold RYBREVANT® and LAZCLUZE® based on severity. Once anticoagulant treatment has been initiated, resume RYBREVANT® and LAZCLUZE® at the same dose level at the discretion of the healthcare provider. In the event of VTE recurrence despite therapeutic anticoagulation, permanently discontinue RYBREVANT® and continue treatment with LAZCLUZE® at the same dose level at the discretion of the healthcare provider.

Instruct patients to limit sun exposure during and for 2 months after treatment with RYBREVANT® or LAZCLUZE® in combination with RYBREVANT®. Advise patients to wear protective clothing and use broad-spectrum UVA/UVB sunscreen. Alcohol-free (e.g., isopropanol-free, ethanol-free) emollient cream is recommended for dry skin.
When initiating RYBREVANT® treatment with or without LAZCLUZE®, administer alcohol-free emollient cream to reduce the risk of dermatologic adverse reactions. Consider prophylactic measures (e.g. use of oral antibiotics) to reduce the risk of dermatologic reactions. If skin reactions develop, start topical corticosteroids and topical and/or oral antibiotics. For Grade 3 reactions, add oral steroids and consider dermatologic consultation. Promptly refer patients presenting with severe rash, atypical appearance or distribution, or lack of improvement within 2 weeks to a dermatologist. For patients receiving RYBREVANT® in combination with LAZCLUZE®, withhold, reduce the dose, or permanently discontinue both drugs based on severity. For patients receiving RYBREVANT® as a single agent or in combination with carboplatin and pemetrexed, withhold, dose reduce or permanently discontinue RYBREVANT® based on severity.
