Regorafenib-pembrolizumab vs. TACE/TARE in Intermediate Stage HCC Beyond Up-to-7
About
REPLACE is a phase III, multicenter, randomized, open-label trial to evaluate the efficacy and safety of regorafenib and pembrolizumab (Rego-Pembro) versus transarterial chemoembolization (TACE) or transarterial radioembolization (TARE) for the first-line treatment of hepatocellular carcinoma (HCC or liver cancer). Approximately 496 patients in around 80 clinical sites worldwide will be randomized to receive either:
- Investigational arm: Regorafenib in combination with pembrolizumab
- Control arm: Transarterial chemoembolization (TACE) or transarterial radioembolization (TARE)
In both arms, patients will receive trial treatment until progressive disease, unacceptable toxicity, deterioration of patient's condition that warrants permanent trial treatment discontinuation or other treatment discontinuation criteria is met. After trial treatment discontinuation, subsequent treatment will be administered according to the Investigator's clinical judgment.
