A Study of Atezolizumab With Lenvatinib or Sorafenib Versus Lenvatinib or Sorafenib Alone in Hepatocellular Carcinoma Previously Treated With Atezolizumab and Bevacizumab (IMbrave251)

May 13, 2026 updated by: Hoffmann-La Roche

A Phase III, Open-Label, Randomized Study of Atezolizumab With Lenvatinib or Sorafenib Versus Lenvatinib or Sorafenib Alone in Hepatocellular Carcinoma Previously Treated With Atezolizumab and Bevacizumab

This is a Phase III, open-label, multicenter, randomized, two-arm study designed to evaluate the efficacy and safety of atezolizumab plus either lenvatinib or sorafenib versus lenvatinib or sorafenib alone in participants with locally advanced or metastatic Hepatocellular Carcinoma (HCC) who have progressed on prior systemic treatment with atezolizumab plus bevacizumab combination.

  • Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1 within 7 days prior to randomization
  • Child-Pugh class A within 7 days prior to randomization
  • Adequate hematologic and end-organ function

Exclusion Criteria:

  • Symptomatic, untreated, or actively progressing central nervous system (CNS) metastases.
  • History of leptomeningeal disease
  • History of hepatic encephalopathy, preceding 6 months, unresponsive to therapy within 3 days
  • Known fibrolamellar HCC, sarcomatoid HCC, or mixed cholangiocarcinoma and HCC
  • History of malignancy other than HCC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Atezolizumab + Lenvatinib or Sorafenib
Participants will receive atezolizumab plus lenvatinib or sorafenib. Treatment will continue until unacceptable toxicity or loss of clinical benefit as determined by the investigator.
Atezolizumab will be administered by intravenous (IV) infusion at a fixed dose of 1200 mg on Day 1 of each 21-day cycle until unacceptable toxicity or loss of clinical benefit as determined by the investigator.
Other Names:
  • Tecentriq
Lenvatinib will be administered once daily by mouth each day of every 21-day study treatment cycle. Participants with a baseline body weight of < 60 kg will receive a daily dose of 8 mg. Participants with a baseline body weight of ≥ 60 kg will receive a daily dose of 12 mg.
Sorafenib will be administered at a dose of 800 mg per day, i.e. two tablets of 200 mg swallowed by mouth twice daily (equivalent to a total daily dose of 800 mg) each day of every 21-day study treatment cycle.
Active Comparator: Lenvatinib or Sorafenib
Participants will receive lenvatinib or sorafenib. Treatment will continue until unacceptable toxicity or loss of clinical benefit as determined by the investigator.
Lenvatinib will be administered once daily by mouth each day of every 21-day study treatment cycle. Participants with a baseline body weight of < 60 kg will receive a daily dose of 8 mg. Participants with a baseline body weight of ≥ 60 kg will receive a daily dose of 12 mg.
Sorafenib will be administered at a dose of 800 mg per day, i.e. two tablets of 200 mg swallowed by mouth twice daily (equivalent to a total daily dose of 800 mg) each day of every 21-day study treatment cycle.
