Study Summary

This trial is testing the combination of two immunotherapy drugs, tiragolumab and atezolizumab, to see if they are effective in treating SMARCB1 or SMARCA4 deficient tumors.

Who is the study for?
This trial is for children and adults with specific aggressive cancers that lack SMARCB1 or SMARCA4 genes. Participants must have recovered from previous cancer treatments, not received certain therapies recently, and have measurable disease. It's open to those aged 12 months and older (under 18 for part A; no upper age limit for part B), who haven't had TIGIT therapy, are not on systemic steroids, and meet blood count and organ function criteria.Check my eligibility
What is being tested?
The trial tests tiragolumab plus atezolizumab in patients with relapsed or refractory tumors lacking the SMARCB1/SMARCA4 genes. This study aims to see if these immunotherapy drugs can help the immune system fight cancer more effectively by preventing tumor growth.See study design
What are the potential side effects?
Potential side effects include reactions related to the immune system such as inflammation of organs, infusion-related reactions like fever or chills, fatigue, digestive issues including nausea or diarrhea, changes in blood counts leading to increased infection risk or bleeding problems.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Part A (atezolizumab, tiragolumab)Experimental Treatment8 Interventions
Patients receive tiragolumab IV over 30-90 minutes on day 1 of each cycle and atezolizumab IV over 30-60 minutes on day 1 of each cycle starting in cycle 2. Treatment repeats every 21 days for up to 5 years in the absence of disease progression or unacceptable toxicity. Patients undergo standard imaging scans including x-rays, CT, MRI, and/or FDG PET-CT, throughout the trial. Patients also undergo blood sample collection on study.
Group II: Arm B (atezolizumab, tiragolumab)Experimental Treatment8 Interventions
Patients receive atezolizumab IV over 30-60 minutes on day 1 and tiragolumab IV over 30-90 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 5 years in the absence of disease progression or unacceptable toxicity. Patients also undergo standard imaging scans including x-rays, CT, MRI, and/or FDG PET-CT throughout the trial. Patients also undergo blood sample collection on study.
