Clinical Trial Summary

This is a Phase 2 trial composed of an open label Lead-In followed by a Randomized Phase designed to evaluate the efficacy and safety of SRF388 in combination with atezolizumab plus bevacizumab compared to placebo (inactive substance) in combination with atezolizumab plus bevacizumab in patients with first-line advanced or metastatic HCC.

Description:

This is a Phase 2 trial designed to evaluate the efficacy and safety of SRF388 in combination with atezolizumab plus bevacizumab (Arm A) compared to placebo in combination with atezolizumab plus bevacizumab (Arm B) in patients with first-line advanced or metastatic HCC.

After a Lead-In Phase of up to 30 patients who will receive open-label SRF388 + atezolizumab + bevacizumab, the blinded Randomized Phase will randomize approximately 104 patients with a 1:1 allocation to Arm A or Arm B and stratified by geographic region (Asia excluding Japan vs. rest of world) and Barcelona Clinic Liver Cancer (BCLC) stage (B or C).
