Type of information: Clinical research agreement
Compound: epacadostat and nivolumab
Company: BMS (USA - NY) Incyte (USA - DE)
Therapeutic area:
Type agreement: clinical research
Action mechanism:
- enzyme inhibitor/immunotherapy product/monoclonal antibody/immune checkpoint inhibitor.
- Nivolumab is a fully-human PD-1 immune checkpoint inhibitor that binds to the checkpoint receptor PD-1 (programmed death-1) expressed on activated T-cells. PD-1, a receptor expressed on the surface of lymphocytes, plays a role in a regulatory pathway that suppresses activated lymphocytes in the body. Available evidence suggests that cancer cells exploit this pathway to escape from immune responses. Opdivo® is thought to provide benefit by blocking PD-1-mediated negative regulation of lymphocytes (i.e., the interaction of PD-1 with its ligands PD-L1 and PD-L2), thereby enhancing the ability of the immune system to recognize cancer cells as foreign and eliminate them. Opdivo® is the world’s first approved drug targeting PD-1.
- This monoclonal antibody has been generated under a research collaboration entered into in May 2005 between Ono and Medarex. When Medarex was acquired by BMS in 2009, it also granted BMS its rights to develop and commercialize the anti-human PD-1 monoclonal antibody in North America. Through the collaboration agreement entered into in September 2011 between Ono and BMS, Ono granted BMS exclusive rights to develop and commercialize Opdivo® in the rest of the world, except in Japan, Korea and Taiwan where Ono has retained all rights to develop and commercialize the compound.
- Indoleamine 2,3-dioxygenase 1 (IDO1) is an immunosuppressive enzyme that has been shown to induce regulatory T cell generation and activation, and allow tumors to escape immune surveillance. Epacadostat is an orally bioavailable small molecule inhibitor of IDO1 that has nanomolar potency in both biochemical and cellular assays and has demonstrated potent activity in enhancing T lymphocyte, dendritic cell and natural killer cell responses in vitro, with a high degree of selectivity. Epacadostat has shown proof-of-concept clinical data in patients with unresectable or metastatic melanoma in combination with the CTLA-4 inhibitor ipilimumab, and is currently in four proof-of-concept clinical trials with PD-1 and PD-L1 immune checkpoint inhibitors in a variety of cancer types.
Disease: first-line non-small cell lung cancer, first-line head and neck cancer, melanoma
Details:
- • On April 2, 2017, BMS and Incyte announced the companies have agreed to advance their clinical development program evaluating the combination of epacadostat, Incyte’s investigational oral selective IDO1 enzyme inhibitor, with Opdivo® (nivolumab), Bristol-Myers Squibb’s PD-1 immune checkpoint inhibitor, into phase 3 registrational studies in first-line non-small cell lung cancer across the spectrum of PD-L1 expression and first-line head and neck cancer. Additionally, the companies are expanding the ECHO-204 Phase 1/2 study, established under a collaboration between the companies in 2014, to include anti-PD-1/PD-L1 relapsed/refractory melanoma cohorts. The expanded clinical development program, including the phase 3 registrational studies, will be co-funded by the two companies.
