JnJ submits application to USFDA for Subcutaneous amivantamab for patients with EGFR-mutated non-small cell lung cancer

Data from the Phase 3 PALOMA-3 study (NCT05388669) presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting and published in the Journal of Clinical Oncology showed SC amivantamab had comparable overall response rates to IV administration in patients with NSCLC with epidermal growth factor receptor (EGFR) exon 19 deletion or L858R mutations. SC amivantamab also demonstrated significantly shorter administration time and a five-fold reduction in infusion-related reactions, alongside longer overall survival, progression-free survival and duration of response. Efficacy results like these have not been seen before in a study assessing IV and SC comparability. The BLA submission includes data from the Phase 2 PALOMA-2 (NCT05498428) study evaluating SC amivantamab in settings where IV amivantamab has been previously submitted for approval and is intended to support dosing schedules of every two and every three weeks.

“RYBREVANT administered intravenously is a foundational treatment for patients with EGFR-mutated NSCLC,” said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Johnson & Johnson Innovative Medicine. “This subcutaneous option, administered in approximately five minutes, is a clinically important advancement that could transform the treatment experience for patients, oncologists and nursing staff. We look forward to working with the FDA and global regulators in the review of these applications.”

The submission follows two recent milestones for the RYBREVANT IV formulation, including the approval of RYBREVANT in combination with chemotherapy as the first FDA-approved therapy for first-line treatment of patients with NSCLC with EGFR exon 20 insertion mutations supported by the Phase 3 PAPILLON study and a CHMP positive opinion for RYBREVANT in combination with chemotherapy for this indication in Europe.

RYBREVANT (amivantamab-vmjw), a fully-human bispecific antibody targeting EGFR and MET with immune cell-directing activity, is approved in the U.S., Europe, and in other markets around the world as monotherapy 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.3 In the subcutaneous formulation, amivantamab is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20), Halozyme’s ENHANZE drug delivery technology.

RYBREVANT is also approved in the U.S. in combination with chemotherapy (carboplatin and pemetrexed) for the first-line treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test. In October 2023, a type II extension of indication application was submitted to the European Medicines Agency (EMA) seeking approval of RYBREVANT for this indication.
