Data from the Phase 3 PALOMA-3 study (NCT05388669) presented at the 2024
RYBREVANT administered intravenously is a foundational treatment for patients with EGFR-mutated NSCLC, said
Today s 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
About PALOMA-3
PALOMA-3 (NCT05388669), which enrolled 418 patients, is a randomized, open-label Phase 3 study evaluating the pharmacokinetics (PK), efficacy and safety of subcutaneous amivantamab (administered via manual injection) combined with lazertinib compared to IV amivantamab and lazertinib in patients with EGFR-mutated advanced or metastatic NSCLC after progression on osimertinib and chemotherapy. The co-primary PK endpoints of the study were trough concentration (Ctrough on Cycle [C] 2 Day [D] 1 or C4D1) and C2 area under the curve (AUCD1-D15). Key secondary endpoints were objective response rate and progression-free survival. Overall survival was a predefined exploratory endpoint. Prophylactic anticoagulation was recommended for the first four months of treatment.1
About the PALOMA-2 Study
PALOMA-2 (NCT05498428) is an open-label Phase 2 study evaluating the efficacy, safety, and PK of first-line SC amivantamab (administered via manual injection) combined with lazertinib and/or chemotherapy in patients with EGFR-mutated advanced or metastatic NSCLC. Sixty-eight and 58 patients were enrolled in Cohorts 1 and 6, respectively. Prophylactic anticoagulation for the first four months of treatment was recommended in Cohort 1 and mandatory in Cohort 6. The primary endpoint was objective response rate (ORR) as assessed by the investigator per RECIST v1.1.2

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for NSCLC prefer next-generation sequencing-based strategies over polymerase chain reaction-based approaches for the detection of EGFR exon 20 insertion variants.
The NCCN Guidelines include: Amivantamab-vmjw (RYBREVANT) plus carboplatin and pemetrexed as a preferred (Category 1 recommendation) first-line therapy in treatment-naive patients with newly diagnosed advanced or metastatic EGFR exon 20 insertion mutation-positive advanced NSCLC, or as a subsequent therapy option (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.4 (+)(++)
Amivantamab-vmjw (RYBREVANT) plus chemotherapy as a preferred (Category 1 recommendation) subsequent therapy for patients with locally advanced or metastatic NCSLC with EGFR exon 19 deletions or exon 21 L858R mutations who experienced disease progression after treatment with osimertinib.4 (+)(++)
Amivantamab-vmjw (RYBREVANT) as a subsequent therapy option (Category 2A recommendation) for patients that have progressed on or after platinum-based chemotherapy with or without an immunotherapy and have EGFR exon 20 insertion mutation-positive NSCLC.4 (+)(++)
RYBREVANT is being studied in multiple clinical trials in NSCLC, including: The Phase 1 PALOMA (NCT04606381) study assessing the feasibility of subcutaneous administration of amivantamab based on safety and pharmacokinetics and to determine a dose, dose regimen and formulation for amivantamab subcutaneous delivery.5
The Phase 2 PALOMA-2 (NCT05498428) study assessing subcutaneous amivantamab in patients with advanced or metastatic solid tumors including EGFR-mutated NSCLC.2
The Phase 3 PALOMA-3 (NCT05388669) study assessing lazertinib with subcutaneous amivantamab compared to intravenous amivantamab in patients with EGFR-mutated advanced or metastatic NSCLC.1
The Phase 3 PAPILLON (NCT04538664) study assessing RYBREVANT in combination with carboplatin-pemetrexed versus chemotherapy alone in the first-line treatment of patients with advanced or metastatic NSCLC with EGFR exon 20 insertion mutations.6
The Phase 3 MARIPOSA-2 (NCT04988295) study assessing the efficacy of RYBREVANT (with or without lazertinib) and carboplatin-pemetrexed versus carboplatin-pemetrexed alone in patients with locally advanced or metastatic EGFR ex19del or L858R substitution NSCLC after disease progression on or after osimertinib.7
The Phase 3 MARIPOSA (NCT04487080) study assessing RYBREVANT in combination with lazertinib versus osimertinib and versus lazertinib alone in the first-line treatment of patients with locally advanced or metastatic NSCLC with EGFR ex19del or L858R substitution mutations.8

About Lazertinib
Lazertinib is an oral, third-generation, brain-penetrant EGFR tyrosine kinase inhibitor (TKI) that targets both the T790M mutation and activating EGFR mutations while sparing wild type-EGFR. An analysis of the efficacy and safety of lazertinib from the Phase 3 study was published in
About Non-Small Cell
Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases.15,16 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.17 Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.18 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.17, 17, 19, 20, 21, 22 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.23 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.24, 25 EGFR exon 20 insertion mutations are the third most prevalent activating EGFR mutation.26 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.27
