An Observational Study to Learn More About How Well a Treatment Works When Given After Treatment With Atezolizumab and Bevacizumab or Another Similar Combination of Drugs in Adults With Liver Cancer That Cannot be Treated With Surgery

Study Summary

This is an observational study in which only data will be collected from adults with unresectable hepatocellular carcinoma. These adults should be prescribed a different treatment after treatment with atezolizumab and bevacizumab, or another similar combination of drugs, by their doctors. Unresectable hepatocellular carcinoma (uHCC) is a type of liver cancer that cannot be treated with surgery. In the past, sorafenib was the only approved first-line anti-cancer drug for people with uHCC. Regorafenib and other drugs were approved as second-line treatments for uHCC if a person could not take sorafenib or it stopped working for them. Lately, another first-line (1L) treatment called immuno-oncology (IO) immune checkpoint inhibitor combination (1L-IO combo), like atezolizumab with bevacizumab (AB), has become the preferred choice of treatment. This is because of the meaningful impact on patient survival. 1L-IO combo are drugs that help the body's defense system recognize and kill cancer cells. Since the other treatments were previously approved for use following sorafenib, the best order to take these treatments in following an 1L-IO combo is unknown. To better understand and determine this order, more knowledge is needed about how well different treatments work in participants with uHCC who have been treated with AB or another 1L-IO combo. The main purpose of this study is to learn more about how well different treatments work when given after first-line treatment with AB or another approved 1L-IO combo. To do this, researchers will collect data on how long the participants live (also called overall survival) from the start of any treatment given after the first-line treatment. In addition, researchers will also collect the following information to learn more about the participants who will be given a different treatment after the 1L-IO combo: * characteristics including age, sex, and race, and signs and symptoms of the participants over the duration of their fi

Primary Outcome

OS is defined as the time (days) from start of second-line systemic treatment to the date of death, due to any cause. Patients alive or lost to follow-up will be censored at their last date of follow-up.
