Company: BMS (USA - NY)
Product: Opdivo® (nivolumab)+Yervoy® (ipilimumab)
Action
mechanism:
- monoclonal antibody/immune checkpoint inhibitor . Nivolumab is an investigational, 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.
- Cytotoxic T-lymphocyte antigen-4 (CTLA-4) is a negative regulator of T-cell activation. Ipilimumab binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation. The mechanism of action of ipilimumab’s effect in patients with melanoma is indirect, possibly through T-cell mediated anti-tumor immune responses.

Trial
details:
- CheckMate -214 is a phase 3, randomized, open-label study evaluating the combination of Opdivo plus Yervoy versus sunitinib in patients with previously untreated advanced or metastatic renal cell carcinoma. Patients in the combination group received Opdivo 3 mg/kg plus Yervoy 1 mg/kg every 3 weeks for 4 doses followed by Opdivo 3 mg/kg every 2 weeks. Patients in the comparator group received sunitinib 50 mg once daily for 4 weeks, followed by 2 weeks off before continuation of treatment. Patients were treated until progression or unacceptable toxic effects. The primary endpoints of the trial are progression-free survival, overall survival and objective response rate in an intermediate to poor-risk patient population (approximately 75 percent of patients). The majority of alpha was allocated to overall survival. Safety is a secondary endpoint.
Latest
news:
- • On August 15, 2017, BMS announced topline results from the CheckMate -214 trial investigating Opdivo® (nivolumab) in combination with Yervoy® (ipilimumab) versus sunitinib in intermediate and poor-risk patients previously untreated advanced or metastatic renal cell carcinoma. The combination met the co-primary endpoint of objective response rate (ORR) and achieved a 41.6% ORR versus 26.5% for sunitinib. Median duration of response was not reached for the combination of Opdivo® and Yervoy® and was 18.17 months for sunitinib. While there was an improvement in progression-free survival (PFS) (HR=0.82, [99.1% CI 0.64 – 1.05]; stratified 2-sided p=0.03), it did not reach statistical significance. The median PFS was 11.56 months (95% CI 8.71 – 15.51) for the Opdivo® and Yervoy® combination versus 8.38 months (95% CI 7.03-10.81) for sunitinib, The study will continue as planned to allow the third co-primary endpoint of overall survival to mature. The tolerability profile observed in CheckMate-214 was consistent with that observed in previously reported studies of this dosing schedule.
