Merck (NYSE: MRK), known as MSD outside of the United States and Canada, and Moderna, Inc. (Nasdaq: MRNA), announced the initiation of INTerpath-009, a pivotal Phase 3 randomized clinical trial evaluating V940 (mRNA-4157), an investigational individualized neoantigen therapy (INT), in combination with KEYTRUDA^® (pembrolizumab), Merck’s anti-PD-1 therapy, as adjuvant treatment for patients with resectable Stage II, IIIA or IIIB (N2) non-small cell lung cancer (NSCLC) who did not achieve a pathological complete response (pCR) after receiving neoadjuvant KEYTRUDA plus platinum-based chemotherapy. Global recruitment in INTerpath-009 has begun, and the first patients have now started enrolling in Canada.

“While the overall survival rates for patients with non-small cell lung cancer have significantly improved in recent years, lung cancer continues to be the leading cause of cancer death worldwide,” said Dr.Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. “We are pleased to expand the INTerpath clinical trial program with Moderna, evaluating V940 (mRNA-4157), a promising new modality, in combination with KEYTRUDA to pursue meaningful advances for lung cancer and bring more options to patients with earlier stages of disease, where we potentially can have the most impact.”

“We are excited to build on our ongoing collaboration with our colleagues at Merck by expanding our research efforts for patients with NSCLC,” said Kyle Holen, M.D., Moderna's senior vice president and head of development, Therapeutics and Oncology. “We believe that our mRNA technology has the potential to improve the outcomes of those affected by lung cancer, and together, INTerpath-002 and INTerpath-009 are designed to demonstrate this potential in early-stage lung cancer, with and without prior neoadjuvant therapy.”

Ongoing clinical development programs

Merck and Moderna have initiated Phase 3 randomized clinical trials evaluating mRNA-4157 (V940) in combination with KEYTRUDA as an adjuvant treatment in patients with resected high-risk (Stage IIB-IV) melanoma (INTerpath-001, NCT05933577) and non-small cell lung cancer (INTerpath-002, NCT06077760).

In 2024, Merck and Moderna also initiated a two-part Phase 2/3 randomized clinical trial evaluating mRNA-4157 (V940) in combination with KEYTRUDA as neoadjuvant and adjuvant treatment in patients with resectable locally advanced Stage II-IV (M0) cutaneous squamous cell carcinoma (INTerpath-007, NCT06295809), a Phase 2 randomized clinical trial evaluating mRNA-4157 (V940) in combination with KEYTRUDA as adjuvant treatment in patients with intermediate-high-risk, high-risk, or M1 no evidence of disease renal cell carcinoma (INTerpath-004, NCT06307431), and a Phase 2 randomized clinical trial evaluating mRNA-4157 (V940) in combination with KEYTRUDA as adjuvant treatment in patients with high-risk muscle-invasive urothelial carcinoma post-radical resection (INTerpath-005, NCT06305767).
