Abstract
Background: Neoantigens are immunogenic molecules arising from patient-specific tumor mutations. Intismeran autogene (intismeran; formerly V940, mRNA-4157), an mRNA-based individualized neoantigen therapy (INT) encoding ≤34 neoantigens unique to each patient's tumor, is designed to promote an antitumor immune response. In early-phase studies, adjuvant intismeran plus pembrolizumab showed antitumor activity with solid tumors. Standard-of-care therapy for non-small cell lung cancer (NSCLC) tumors ≥4 cm includes platinum-based chemotherapy and pembrolizumab given after (adjuvant) or both before and after (perioperative) surgical resection. We describe study designs for the INTerpath-002 and INTerpath-009 studies evaluating the addition of intismeran to adjuvant pembrolizumab-based therapy in stage II-IIIB (N2) NSCLC.
Methods: INTerpath-002 and INTerpath-009 are randomized, double-blind, phase 3 trials. Eligible participants for INTerpath-002 have completely resected, margin-negative, stage II-IIIB (N2) NSCLC (American Joint Committee on Cancer staging manual, eighth edition) and have received 1 to 4 cycles of adjuvant platinum-based chemotherapy. Eligible participants for INTerpath-009 have resectable stage II-IIIB (N2) NSCLC and have received ≤4 cycles of neoadjuvant pembrolizumab plus chemotherapy every 3 weeks. Participants with tumors that do not achieve a pathologic complete response, per pathologic examination of the resected tumor specimen, and have R0-R1 resection are eligible for randomized treatment. In both studies, participants are randomized 1:1 to receive pembrolizumab intravenously every 6 weeks plus either intismeran intramuscularly every 3 weeks or placebo. The primary endpoint in both studies is disease-free survival per investigator.
Results: Recruitment is ongoing for both studies.
Conclusions: Results from these studies will provide insight into the potential role of INT in NSCLC.
