Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, certain medications like systemic immunosuppressive drugs and some investigational agents must be stopped before starting the trial. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug Atezolizumab +/- Bevacizumab for Alveolar Soft Part Sarcoma?

Atezolizumab has been approved for treating alveolar soft part sarcoma, showing effectiveness in both adults and children. Bevacizumab, when used alone, has also shown positive results in patients with this type of cancer, suggesting that these drugs may be beneficial when used together.12345

Is the combination of Atezolizumab and Bevacizumab safe for humans?

Atezolizumab (Tecentriq) and Bevacizumab (Avastin) have been studied for safety in various conditions. Atezolizumab is approved for use in certain cancers, and Bevacizumab has shown safety in treating a 90-year-old patient with alveolar soft part sarcoma, resulting in improved symptoms and disease response.12456

How is the drug combination of Atezolizumab and Bevacizumab unique for treating alveolar soft part sarcoma?

The combination of Atezolizumab (an immune checkpoint inhibitor) and Bevacizumab (a drug targeting blood vessel growth) is unique for treating alveolar soft part sarcoma because it combines immune system activation with inhibition of blood supply to the tumor, offering a novel approach for a condition that is typically resistant to standard chemotherapy.12345

What is the purpose of this trial?

This phase II trial studies how well atezolizumab or atezolizumab plus bevacizumab works in treating patients with alveolar soft part sarcoma that has not been treated, has spread from where it started to other places in the body (advanced) and cannot be removed by surgery (unresectable). Atezolizumab works by unblocking the immune system, allowing the immune system cells to recognize and then attack tumor cells. Bevacizumab works by controlling the growth of new blood vessels. Giving atezolizumab alone or atezolizumab with bevacizumab may shrink the cancer.

Eligibility Criteria

This trial is for people with advanced alveolar soft part sarcoma that can't be removed by surgery. Participants must have certain blood cell counts, organ function levels, and a life expectancy over 3 months. They should not have had recent severe infections or major surgeries, and cannot be pregnant or breastfeeding. Adults and children over 2 years old may join; however, only adults can receive the combination treatment.

Inclusion Criteria

I don't have issues with wound healing, heart conditions, stomach problems, or allergies to medications.
My alveolar soft part sarcoma cannot be cured with surgery.
My condition worsened after taking atezolizumab alone.

Treatment Details

Interventions

  • Atezolizumab
  • Bevacizumab
Trial Overview Researchers are testing if atezolizumab alone or combined with bevacizumab is effective in treating this type of sarcoma. Atezolizumab aims to boost the immune system's ability to fight cancer cells while bevacizumab targets tumor blood supply.

Group I: Arm II (atezolizumab, bevacizumab)Experimental Treatment4 Interventions
Patients receive atezolizumab IV over 30-60 minutes and bevacizumab IV over 30-90 minutes on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT imaging, and collection of blood and urine at baseline.

Findings from Research

Atezolizumab (Tecentriq) is an FDA-approved treatment for unresectable or metastatic alveolar soft part sarcoma (ASPS), showing a 24% overall response rate in a clinical trial with 49 patients, and a durable response rate of 67% at 6 months and 42% at 12 months.
The treatment has a manageable safety profile, with common severe side effects including musculoskeletal pain (8%) and hypertension (6%), making it a viable option for patients with limited treatment alternatives for this high-risk disease.
