Tremelimumab plus Durvalumab in Unresectable Hepatocellular Carcinoma

🤖 Plain-English Summary

BACKGROUND: A single, high priming dose of tremelimumab (anti-cytotoxic T lymphocyte–associated antigen 4) plus durvalumab (anti–programmed cell death ligand-1), an infusion regimen termed STRIDE (Single Tremelimumab Regular Interval Durvalumab), showed encouraging clinical activity and safety in a phase 2 trial of unresectable hepatocellular carcinoma. Durvalumab monotherapy was noninferior to sorafenib for patients with unresectable hepatocellular carcinoma.

🔑 Key Findings

• METHODS: In this global, open-label, phase 3 trial, the majority of the patients we enrolled with unresectable hepatocellular carcinoma and no previous systemic treatment were randomly assigned to receive one of three regimens: tremelimumab (300 mg, one dose) plus durvalumab (1500 mg every 4 weeks; STRIDE), durvalumab (1500 mg every 4 weeks), or sorafenib (400 mg twice daily).
• The primary objective was overall survival for STRIDE versus sorafenib.
• Noninferiority for overall survival for durvalumab versus sorafenib was a secondary objective.
