Opdivo Precision Cancer Medicine Improves Outcomes in Advanced Liver Cancer
by Dr. C.H.Weaver M.D. updated 3/2020
Results from the CheckMate 040 clinical trial have been reported and found that Opdivo (nivolumab), an immuno-oncology drug which acts by modulating the immune system, produces durable responses with long-term survival rates in patients with liver cancer, regardless of whether or not patients were infected with Hepatitis B or C.
Liver cancer, or hepatocellular carcinoma (HCC), is the second most common cause of cancer-related deaths worldwide. (1,2) The prognosis for patients with advanced liver cancer is poor, and the multikinase inhibitor, Nexaver, had been the only approved treatment until recently. (3,4)
Opdivo is a programmed-death-1 (PD-1) immune checkpoint inhibitor that is designed to use the body’s own immune system to help restore the anti-cancer immune response. It restores T-cell-mediated anti-cancer activity so that the T cells recognize and attack cancer cells. (5)
These study results were initially presented at The International Liver Congress 2017 in Amsterdam, and showed that the overall response rate was 19.3% in patients previously treated with Nexaver (sorafenib), and responses were ongoing in 71% of patients. Overall ~ 60% of these advanced patients were alive greater than one year from beginning Opdivo.

The CheckMate 040 clinical trial was designed to evaluate Opdivo in patients with advanced liver cancer who were previously treated with Nexavar and were not suitable for surgery. (6) All 145 patients were treated with intravenous Opdivo every 2 weeks until the cancer progressed or side effects became intolerable. In addition to the overall response rate of 19%, average overall survival was 16.7 months. Responses to Opdivo occurred regardless of programmed death-1 (PD-1) ligand expression on cancer cells.
On March 11, 2020, the FDA approved Opdivo plus Yervoy for the treatment of patients with advanced HCC previously given Nexavar based on findings from the phase CheckMate-040 clinical trial. After a minimum follow-up time frame of 28 months, 33% of the 49 patients responded to therapy including 4 (8%) complete responses and 12 partial responses. Duration of response ranged from 4.6 to greater than 30 months, with 88% lasting at least 6 months, and 31% at least 24 months. (7)
