Refametinib(BAY86-9766) in RAS Mutant Hepatocellular Carcinoma (HCC)

A Prospective, Single-arm, Multicenter, Uncontrolled, Open-label Phase II Trial of Refametinib (BAY86-9766) in Patients With RAS Mutant Hepatocellular Carcinoma (HCC)

This is a study to investigate the potential clinical benefit of refametinib in patients with unresectable or metastatic HCC carrying a RAS mutation. The study will be conducted in 2 stages. Approximately 95 patients (15 at Stage 1/ 80 at Stage 2) will be accrued to this study to receive treatment. Stage 2 of the trial will only be conducted if at least 5 out of 15 patients at Stage 1 show at least confirmed partial response (PR) according to modified response evaluation criteria in solid tumors (mRECIST) assessed by central image review.

Refametinib is an oral (i.e. taken by mouth) protein kinase inhibitor. A kinase inhibitor targets certain key proteins that are essential for the survival of the cancer cell. By specifically targeting these proteins, refametinib may stop cancer growth. The growth of the tumor may be decreased by preventing these specific proteins from functioning.

The primary endpoint (the most meaningful result to be tracked) of this study is based on the rate of response, i.e. the disease getting smaller. The aim is to show that the therapy with refametinib improves the response rate in this RAS mutation patient population.

Eligibility criteria for RAS mutation testing

• Unresectable or metastatic HCC, confirmed either by histology or clinically according to the American Association for the Study of Liver Disease (AASLD) criteria for cirrhotic patients. For non-cirrhotic patients, histological confirmation is mandatory.
• Male or female ≥18 years of age.
• Eastern Cooperative Oncology Group (ECOG) performance state 0 or 1.
• Life expectancy of at least 12 weeks.
• No prior use of targeted agents, experimental therapy or systemic anti-cancer treatment for HCC (except sorafenib)
