Rahway: Merck, known as MSD outside of the United States and Canada, and Moderna, Inc., 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.”Read also: Merck’s KEYTRUDA Gains European Approval for Two New Gynecologic Cancer Treatments“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.”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). mRNA-4157 (V940) is a novel investigational messenger RNA (mRNA)-based individualized neoantigen therapy (INT) consisting of a synthetic mRNA coding for up to 34 neoantigens that is designed and produced based on the unique mutational signature of the DNA sequence of the patient’s tumor. Upon administration into the body, the algorithmically derived and RNA-encoded neoantigen sequences are endogenously translated and undergo natural cellular antigen processing and presentation, a key step in adaptive immunity. Individualized neoantigen therapies are designed to train and activate an antitumor immune response by generating specific T-cell responses based on the unique mutational signature of a patient’s tumor. KEYTRUDA is an immunotherapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. As previously announced from the Phase 2b KEYNOTE-942/mRNA4157-P201 trial evaluating patients with high-risk stage III/IV melanoma, combining mRNA-4157 (V940) with KEYTRUDA may provide a meaningful benefit over KEYTRUDA alone. Merck and Moderna continue to evaluate and expand the V940 INTerpath clinical development program for additional tumor types and treatment settings.Read also: Merck eyes more acquisitions for life science after USD 600M Mirus Bio deal
