Study Investigating the Association of NP137 With Atezolizumab-Bevacizumab Combination in First Line in Unresectable HCC

Launched by UNIVERSITY HOSPITAL, GRENOBLE · Sep 15, 2022

ClinConnect Summary

This clinical trial is looking into a new treatment for patients with unresectable hepatocellular carcinoma (HCC), which is a type of liver cancer that cannot be surgically removed. The study is testing a combination of NP137, a new investigational drug, with two standard drugs, Atezolizumab and Bevacizumab. The goal is to see if this combination is safe and can help improve tumor response and survival rates in patients starting treatment for their cancer.

To participate, you must be at least 18 years old and have a confirmed diagnosis of unresectable HCC that has not been treated with systemic therapy before. You also need to have a certain level of liver function and meet other specific health criteria. If eligible, patients can expect to undergo regular monitoring and assessments during the trial to track their health and the effects of the treatment. It's important to note that this trial is currently recruiting participants, and those who are interested should talk to their healthcare provider for more information about participation.
