Liver-NET1: Study Investigating the Association of NP137 With Atezolizumab-Bevacizumab Combination in First Line in Unresectable Hepatocellular Carcinoma
Study Details
Study Description
Brief Summary
The study will assess the safety of the association of NP137 with the standard of care Atezolizumab-Bevacizumab in first line setting in patients with unresectable hepatocellular carcinoma.The study drug which is tested is the NP137 in association with Atezolizumab-Bevacizumab to allow a better tumor response as well as better survival outcomes with an acceptable safety.

| Phase 1 |
Detailed Description
The study is a multicentric, prospective, single arm phase 1b trial. This study will enroll 43 to 52 patients and consists of 2 parts: Safety Lead-in Phase and Expansion Phase. Initially, 3 to 12 patients will be enrolled into a Safety Lead-in Phase based on a 3 + 3 design, with the possibility of dose de-escalation, to confirm the recommended dose of NP137 .The Expansion Phase will start after completion of Safety Lead-in Phase at the confirmed dose and will include 40 patients. Patients will be assigned to the experimental single arm (NP137+ Atezolizumab-Bevacizumab).
