What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a combination of three drugs—tiragolumab, atezolizumab, and bevacizumab—to treat advanced liver cancer that cannot be removed by surgery. These drugs help the immune system fight cancer and cut off the tumor's blood supply. The goal is to see if this combination is safe and effective for these patients.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop your current medications. However, you cannot have had prior systemic treatment for liver cancer or be on systemic immunosuppressive or immunostimulatory medications.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it excludes those on systemic immunosuppressive or immunostimulatory medications, so you might need to stop those if you're taking them.

What safety data is available for the treatment of atezolizumab plus bevacizumab for liver cancer?

The combination of atezolizumab and bevacizumab has been approved by the FDA for the treatment of advanced hepatocellular carcinoma (HCC) based on the IMbrave150 study. Common adverse reactions in more than 20% of patients include hypertension, fatigue/asthenia, and proteinuria. Hemorrhage was reported in 25% of patients. The treatment has shown improved overall survival and progression-free survival compared to sorafenib, a standard treatment. Safety evaluations, including checking for varices, are recommended before starting treatment. Additional studies have confirmed the safety and efficacy of this combination in various patient populations, including older adults and those with viral infections. ^{1 2 3 4 5}

Is the combination of Atezolizumab and Bevacizumab safe for liver cancer patients?

The combination of Atezolizumab and Bevacizumab has been approved for liver cancer and is generally considered safe, but common side effects include high blood pressure, tiredness, and protein in the urine. There is also a higher risk of bleeding, so patients should be checked for certain conditions before starting treatment. ^{1 2 3 4 6}
