On December 7, 2017 Neon Therapeutics, a clinical-stage immuno-oncology company developing neoantigen-based therapeutics, reported that it has entered a clinical trial collaboration with Merck (known as MSD outside the United States and Canada) to evaluate Neon Therapeutics’ proprietary personal neoantigen vaccine, NEO-PV-01, in combination with Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab), along with chemotherapy (Press release, Neon Therapeutics, DEC 7, 2017, View Source [SID1234522428]).

NEO-PV-01 is Neon Therapeutics’ most advanced product candidate, and is a personal neoantigen vaccine based on DNA mutations from each patients’ tumor. Neon Therapeutics and Merck will collaborate on a Phase 1b clinical trial that will examine the safety, tolerability and preliminary efficacy of NEO-PV-01 in combination with KEYTRUDA, pemetrexed and carboplatin in patients with untreated advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC). Additionally, the trial will assess neoantigen-specific immune responses in peripheral blood and tumor tissue, and other markers of immune response.
"We believe there is a strong mechanistic rationale to explore the combination of a personal neoantigen cancer vaccine, anti-PD-1 therapy and chemotherapy," said Richard Gaynor, M.D., president of research and development at Neon Therapeutics. "Together with a growing set of clinical collaborators, we are working to amass a diverse set of clinical data to understand the potential of NEO-PV-01 to improve durability and response rates in combination with multiple immuno-oncology targets."
The collaboration agreement is between Neon Therapeutics, Inc. and Merck, through a subsidiary. Additional details were not disclosed.
