What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and effectiveness of a new treatment combination for liver cancer. It evaluates how well tiragolumab works with two other drugs, atezolizumab (Tecentriq) and bevacizumab (Avastin), for advanced liver cancer that cannot be removed by surgery. Individuals with advanced liver cancer who have not received systemic therapy and whose condition is not manageable with surgery or local treatments may qualify for this trial. As a Phase 3 trial, it represents the final step before FDA approval, providing access to a potentially groundbreaking treatment.

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.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that combining tiragolumab with atezolizumab and bevacizumab is generally safe for people with liver cancer. Research indicates that adding tiragolumab does not significantly increase serious side effects compared to using only atezolizumab and bevacizumab. These two drugs have already been used successfully to treat liver cancer and are usually well-tolerated. While the combination is generally safe, every treatment can have some side effects. Prospective participants should discuss potential risks and benefits with a healthcare provider before joining a trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of atezolizumab, bevacizumab, and tiragolumab for liver cancer because this approach brings a fresh angle to treatment. Unlike the current standard, which often involves therapies like sorafenib or lenvatinib, this combination leverages a potent trio of immune-based treatments. Atezolizumab and bevacizumab work by unleashing the immune system against cancer and cutting off its blood supply, while tiragolumab adds a novel layer by targeting the TIGIT pathway, a recently explored immune checkpoint. This unique mechanism might enhance immune response beyond what's possible with existing therapies, offering hope for more effective liver cancer treatment.

What evidence suggests that this trial's treatments could be effective for liver cancer?

Research has shown that the combination of atezolizumab and bevacizumab is a standard treatment for advanced liver cancer, helping patients live longer. This combination blocks proteins that aid cancer cell growth. In this trial, one group of participants will receive atezolizumab, bevacizumab, and tiragolumab, while another group will receive atezolizumab, bevacizumab, and a placebo. Researchers initially thought that adding tiragolumab might enhance effectiveness. However, recent studies found that including tiragolumab did not significantly extend the time patients lived without their cancer worsening compared to using only atezolizumab and bevacizumab. Despite this, the combination of atezolizumab and bevacizumab remains a proven first-choice treatment for liver cancer. ^{1 2 3 6 7}
