Approval based on compelling safety and efficacy from the Phase 3 MARIPOSA-2 study, marking the third new indication for RYBREVANT^® this year, with four indications overall

RARITAN, N.J., Sept. 19, 2024 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) announced today that the U.S. Food and Drug Administration (FDA) approved RYBREVANT^® (amivantamab-vmjw) in combination with standard of care chemotherapy (carboplatin and pemetrexed) for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions (ex19del) or L858R substitution mutations, whose disease has progressed on or after treatment with an EGFR tyrosine kinase inhibitor (TKI).¹

"RYBREVANT plus chemotherapy may address the most common mechanisms of treatment resistance to third generation EGFR TKIs, such as osimertinib, in the first line," said Martin Dietrich*, M.D., Ph.D., Oncologist, Cancer Care Centers of Brevard. "This multitargeted combination extended progression-free survival and improved overall response compared to chemotherapy alone, offering an important and effective new second-line option for patients."

The five-year survival rate is less than 20 percent for all people with advanced EGFR-mutated NSCLC.^2,3 Acquired resistance mechanisms after TKI monotherapy are diverse and polyclonal, making targeted therapy at progression more difficult, thus limiting the efficacy of targeted therapies at progression.^4,5 Adding immunotherapy to chemotherapy has also failed to demonstrate clinically meaningful improvements.^6,7

"The progression-free survival benefits seen in the MARIPOSA-2 study are exciting," said Andrea Ferris**, President and CEO, LUNGevity Foundation. "It is good to see new therapeutic options like the combination of RYBREVANT and chemotherapy helping to address unmet needs impacting individuals with EGFR-mutated lung cancer, with the potential for positive change, which gives hope to more patients and their families."

The FDA approval is based on results from the Phase 3 MARIPOSA-2 (NCT04988295) study evaluating the efficacy and safety of RYBREVANT^® in combination with chemotherapy for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR ex19del or L858R substitution mutations after disease progression on or after osimertinib.¹ Results showed RYBREVANT^® plus chemotherapy reduced the risk of disease progression or death (progression-free survival [PFS]) by 52 percent vs. chemotherapy alone, the study's primary endpoint.¹ The median PFS for patients receiving RYBREVANT^® plus chemotherapy was 6.3 months, compared to 4.2 months for chemotherapy alone.¹ Additionally, RYBREVANT^® plus chemotherapy showed a confirmed overall response rate (ORR) of 53 percent compared to 29 percent with chemotherapy alone.¹

Amivantamab-vmjw (RYBREVANT^®) in combination with chemotherapy is the only National Comprehensive Cancer Network^®(NCCN^®) Clinical Practice Guidelines in Oncology (NCCN Guidelines^®) Category 1 treatment option for patients with EGFR-mutated NSCLC progressing on osimertinib who are symptomatic with multiple lesions.⁸ ^†‡

"This milestone reinforces RYBREVANT as an important treatment option for patients with EGFR-mutated NSCLC who continue to face high unmet needs after disease progression on or after TKI therapy," said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Johnson & Johnson Innovative Medicine. "Patients need and deserve effective, targeted approaches across all lines of therapy. With RYBREVANT-based regimens, we are bringing potential new standards of care to the nearly 30,000 patients diagnosed with EGFR-mutated NSCLC in the United States each year."

The safety profile of RYBREVANT^® in combination with chemotherapy was consistent with the established profiles of the individual treatments. Permanent discontinuation of RYBREVANT^® due to adverse reactions occurred in 11 percent of patients.¹

MARIPOSA-2 Publications & Presentations
Results from MARIPOSA-2 were first presented in a Presidential Symposium at the European Society of Medical Oncology (ESMO) 2023 Congress (Abstract #LBA15) and simultaneously published in the Annals of Oncology.⁹

Regulatory Milestones
This approval marks the third new indication for RYBREVANT^® this year, following the August 20, 2024, U.S. FDA approval announcement of RYBREVANT^® in combination with LAZCLUZE™ (lazertinib) for the first-line treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or L858R substitution mutations, based on the Phase 3 MARIPOSA study, and the March 1, 2024, U.S. FDA approval announcement of RYBREVANT^® in combination with chemotherapy (carboplatin-pemetrexed) for the first-line treatment of patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, based on the Phase 3 PAPILLON study.¹

On June 17, 2024, Johnson & Johnson also announced the submission of a Biologics License Application to the U.S. FDA for a fixed combination of amivantamab and recombinant human hyaluronidase for subcutaneous administration (SC amivantamab) for all currently approved or submitted indications of intravenous (IV) RYBREVANT^®. This application is based on the Phase 3 PALOMA-3 study, with preliminary results which showed a five-fold reduction in infusion-related reactions (IRR) with a five-minute administration of SC amivantamab.¹⁰ Longer overall survival (OS), PFS and duration of response (DOR) were also observed with SC amivantamab.¹⁰ On August 14, 2024, the U.S. FDA designated this application for Priority Review.

About the MARIPOSA-2 Study

MARIPOSA-2 (NCT04988295), which enrolled 657 patients, is a randomized, open-label Phase 3 study evaluating the efficacy and safety of two combination regimens of RYBREVANT^® (with and without LAZCLUZE™) and chemotherapy.¹¹ Patients with locally advanced or metastatic EGFR ex19del or L858R substitution NSCLC who had disease progression on or after treatment with osimertinib were randomized to treatment with RYBREVANT^®plus chemotherapy, RYBREVANT^® plus chemotherapy with LAZCLUZE™ or chemotherapy alone.¹¹ The dual primary endpoint was used to compare the PFS (using RECIST v1.1 guidelines^§) as assessed by blinded independent central review (BICR) for each experimental arm to chemotherapy alone.¹¹ Secondary endpoints included objective response as assessed by BICR, OS, DOR, time to subsequent therapy, PFS2 and intracranial PFS.¹¹

About Non-Small Cell Lung Cancer (NSCLC)

Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases.^21,22 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma and large cell carcinoma.²³ Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.²⁴ 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.^{23,24,25,26,27,28}EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.²⁹ 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.^2,3 EGFR exon 20 insertion mutations are the third most prevalent activating EGFR mutation.³⁰ Patients with EGFR exon 20 insertion mutations have a real-world five-year 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.³¹

IMPORTANT SAFETY INFORMATION¹
