The primary end point of the lead-in stage was objective response
rate (ORR) at week 12.
The primary end point of the randomized stage was progression-free
survival (PFS).

HBV and HCV infections are associated with manifestations of immune
suppression, including upregulation of programmed death-1 (PD-1) receptor,
T-cell exhaustion, and spontaneous apoptosis of immune cells.
Blockade of the cytotoxic T-lymphocyte antigen-4 receptor by monoclonal
antibodies has shown encouraging activity in patients with HCC and HCV
infection.
Nivolumab is a fully human IgG4 monoclonal antibody to the PD-1 receptor,
blocking the interaction with PD-L1/PD-L2 and restoring T-cell–mediated
antitumor activity

This signs of efficacy were consistent with the more recently reported median OS of 28.6 months (95%CI 16.6–NE) in the population naive to sorafenib, and 15.6 months (95%CI 13.2–18.9) in the much larger population exposed to sorafenib (90% sorafenib progressors).

The FDA has granted an accelerated approval to nivolumab for the treatment
of patients with HCC following prior sorafenib, regardless of PD-L1 status.
The approval is based on 154 patients enrolled in the phase I/II CheckMate-
040 trial, in which the overall response rate (ORR) by blinded independent
central review (BICR) was 18.2% per mRECIST criteria for patients who had
previously been treated with sorafenib. Additionally, 3.2% of patients
experienced a complete response. The ORR by RECIST 1.1 was 14.3% with
nivolumab and the response duration ranged from 3.2 to 38.2+ months.
A phase III randomized trial of nivolumab versus sorafenib has been launched
in the frontline setting, with an enrollment goal of 726 patients. The estimated
primary completion date is October 2018 (NCT02576509).
