Expanded FDA approvals for Opdivo and Keytruda

The US Food and Drug Administration has approved Bristol-Myer’s Squibb’s (NYSE: BMY) Opdivo (nivolumab) injection for intravenous use for the treatment of patients with hepatocellular carcinoma (HCC) who have been previously treated with sorafenib. Approval for this indication has been granted under accelerated approval based on tumor response rate and durability of response.

Continued approval for this indication may be contingent on verification and description of clinical benefit in the confirmatory trials. In the CheckMate -040 trial, 14.3%* (95% CI: 9.2-20.8; 22/154) of patients responded to treatment with Opdivo. The percentage of patients with a complete response was 1.9% (3/154) and the percentage of patients with a partial response was 12.3% (19/154).1 Among responders (n=22), responses ranged from 3.2 to 38.2+ months; 91% of those patients had responses of six months or longer and 55% had responses of 12 months or longer.1

Also on Friday, Merck & Co (NYSE:MRK) announced that the FDA has approved Keytruda (pembrolizumab), the company’s anti-PD-1 (programmed death receptor-1) therapy, for the treatment of patients with recurrent locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors express PD-L1 [Combined Positive Score (CPS) ≥1] as determined by an FDA-approved test, with disease progression on or after two or more prior lines of therapy including fluoropyrimidine- and platinum-containing chemotherapy and if appropriate, HER2/neu-targeted therapy.

This indication is approved under the FDA’s accelerated approval regulations based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials.
