Data show the potential impact of RYBREVANT^® and chemotherapy combination as first-line treatment for patients with advanced non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion mutations

Late-breaking data presented in a Presidential Symposium at 2023 ESMO Congress and simultaneously published in The New England Journal of Medicine

MADRID, Oct. 21, 2023 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new data from the Phase 3 PAPILLON study showing that first-line treatment with RYBREVANT^® (amivantamab-vmjw) in combination with chemotherapy (carboplatin-pemetrexed) resulted in a 60 percent reduction in the risk of disease progression or death (Hazard Ratio [HR]=0.395; 95 percent Confidence Interval [CI], 0.30–0.53; p value P<0.0001) in patients with previously untreated advanced or metastatic NSCLC with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, compared to chemotherapy alone. Results also showed treatment with RYBREVANT^® plus chemotherapy significantly improved objective response rate (ORR) and progression-free survival (PFS) after first subsequent therapy (PFS2). These data were presented in a Presidential Symposium at the European Society of Medical Oncology (ESMO) 2023 Congress taking place October 20-24, 2023 in Madrid, Spain (Abstract #LBA5) and simultaneously published in The New England Journal of Medicine.¹

"We have seen promising outcomes with RYBREVANT in the second-line setting for patients with EGFR exon 20 insertion mutations following platinum-based chemotherapy. However, targeted therapy is generally used as a first-line treatment in other settings to address disease progression earlier and achieve optimal treatment outcomes for patients," said Nicolas Girard,* M.D., Professor of Respiratory Medicine at Versailles Saint Quentin University and Chair of Medical Oncology Department at Institute Curie in Paris, and presenting author. "The significant improvement in progression-free survival and in other efficacy results observed in the PAPILLON study supports RYBREVANT plus chemotherapy as a potential future first-line regimen for these patients."

Treatment with RYBREVANT^® plus chemotherapy resulted in longer PFS (using RECIST v1.1 guidelines^†) as assessed by blinded independent central review (BICR) compared with chemotherapy alone. At a median follow-up of 14.9 months, PFS was significantly prolonged for patients who received RYBREVANT^® plus chemotherapy than for those who received chemotherapy alone (median, 11.4 months and 6.7 months, respectively; HR for disease progression or death=0.395; 95 percent CI, 0.30–0.53; P<0.0001). At 18 months, 31 percent of patients receiving RYBREVANT^® plus chemotherapy remained alive and progression-free compared to 3 percent for patients receiving chemotherapy alone. Treatment with RYBREVANT^® plus chemotherapy showed consistent PFS benefit across patient subgroups.¹

An ORR of 73 percent (95 percent CI, 65–80) was observed for the combination of RYBREVANT^® and chemotherapy compared to 47 percent (95 percent CI, 39–55) in patients receiving chemotherapy alone. Median PFS2 was longer with RYBREVANT^® plus chemotherapy compared to chemotherapy alone (HR=0.493; 95 percent CI, 0.32–0.76; P=0.001), supporting the potential first-line use of RYBREVANT^® and chemotherapy. Notably, of those patients receiving chemotherapy alone, 71 of 94 patients (76 percent) received subsequent RYBREVANT^® treatment as their second line of therapy. An interim overall survival (OS) analysis showed a favorable trend for patients treated with RYBREVANT^® plus chemotherapy compared to those treated with chemotherapy alone (HR=0.675; 95 percent CI, 0.42–1.09; P=0.106), with 72 percent and 54 percent alive at two years, respectively.¹

EGFR and MET-related toxicities were observed with RYBREVANT^® plus chemotherapy, which were mostly Grade 1 and 2, including paronychia, rash, hypoalbuminemia, and peripheral edema. Across both study arms, chemotherapy-associated hematologic and gastrointestinal toxicities were comparable except for higher rates of neutropenia for RYBREVANT^® plus chemotherapy, which were reversible. Few patients discontinued treatment due to adverse reactions in either study arm. No new safety signals were observed with RYBREVANT^®, with the safety profile for the combination of RYBREVANT^® plus chemotherapy consistent with the safety profiles of the individual agents.¹

"Patients with newly diagnosed advanced or metastatic EGFR exon 20 insertion mutation-positive NSCLC are in need of targeted therapies that can be used earlier in the course of their disease, given the tendency for rapid progression and poor outcomes often seen with chemotherapy alone," said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Janssen Research & Development, LLC. "PAPILLON is the first randomized Phase 3 study to show clinically meaningful results for a targeted therapy in combination with chemotherapy – a regimen with the potential to become a practice-changing first-line treatment for these patients."

Results from the PAPILLON study have been submitted to the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for respective reviews.

About the PAPILLON Study
PAPILLON (NCT04538664), which enrolled 308 patients, is a randomized, open-label Phase 3 study evaluating the efficacy and safety of RYBREVANT^®in combination with chemotherapy, compared with chemotherapy alone, in newly diagnosed patients with advanced or metastatic NSCLC characterized by EGFR exon 20 insertion mutations. The primary endpoint of the study is PFS as assessed by BICR. Secondary endpoints include ORR, PFS2, duration of response (DOR), time to subsequent therapy (TST) and OS. Patients who received chemotherapy alone were allowed to receive RYBREVANT^®monotherapy in the second-line setting after confirmation of disease progression.¹

About RYBREVANT^®RYBREVANT^® (amivantamab-vmjw), a fully-human bispecific antibody targeting EGFR and MET with immune cell-directing activity, received accelerated approval by the FDA in May 2021 for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.² This indication is approved under accelerated approval based on overall response rate and DOR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. RYBREVANT^®has also received approval from health authorities in Europe, as well as other markets around the world. In August 2023, Janssen submitted a supplemental Biologics License Application (sBLA) to the U.S. FDA for the expanded approval of RYBREVANT^® in combination with chemotherapy (carboplatin-pemetrexed) for the first-line treatment of patients with NSCLC with EGFR exon 20 insertion mutations. A marketing authorization application has also been submitted to the EMA seeking approval for this combination of RYBREVANT^® and chemotherapy.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines^®) for Non-Small Cell Lung Cancer^‡ prefer next-generation sequencing-based strategies over polymerase chain reaction-based approaches for the detection of EGFR exon 20 insertion variants and include amivantamab-vmjw (RYBREVANT^®) as a subsequent therapy option with a Category 2A recommendation for patients that have progressed on or after platinum-based chemotherapy with or without immunotherapy and have EGFR exon 20 insertion mutation-positive advanced NSCLC.^3§^‖
