Research Sponsored by National Cancer Institute (NCI)

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Age >= 18 years

No prior systemic therapy for peritoneal mesothelioma is allowed. No concurrent radiotherapy is allowed

Must not have

For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated

Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load

Timeline

Screening 3 weeks

Treatment Varies

Follow Up from study entry to the first of either disease progression or death from any cause, where disease progression will be determined based on response evaluation criteria in solid tumors (recist) 1.1 criteria, assessed up to 3 years

Awards & highlights

No Placebo-Only Group

Summary

This trial is testing immunotherapy (atezolizumab) in addition to the usual treatment of surgery or chemotherapy in patients with peritoneal mesothelioma.

Who is the study for?

Adults with untreated malignant peritoneal mesothelioma, without a history of central nervous system disease, significant bleeding disorders, or severe heart conditions. They must have functioning major organs and no autoimmune diseases (with some exceptions like controlled thyroid issues). Women must not be pregnant or nursing and agree to use birth control.

What is being tested?

The trial is testing the effectiveness of adding immunotherapy (atezolizumab) to the usual treatment for peritoneal mesothelioma which includes surgery and chemotherapy drugs like carboplatin and pemetrexed. The goal is to see if atezolizumab helps the immune system fight cancer better than standard treatments alone.

What are the potential side effects?

Potential side effects include allergic reactions to medication, increased risk of infection due to immune system suppression, bleeding complications, high blood pressure from bevacizumab, liver function changes, fatigue, nausea from chemotherapy drugs, and possible organ inflammation from atezolizumab.

Experimental Treatment

Active Control

Group I: Arm I (carboplatin, pemetrexed, bevacizumab, atezolizumab)Experimental Treatment9 Interventions

Patients receive atezolizumab IV over 60 minutes, bevacizumab IV over 30-90 minutes, carboplatin IV over 30 minutes, and pemetrexed IV over 10 minutes on day 1. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Within 4-8 weeks, patients undergo cytoreductive surgery and HIPEC. Patients not eligible for surgery may receive atezolizumab and bevacizumab in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan and PET scan on study. Patients also undergo blood and tissue sample collection on study.

Group II: Arm II (carboplatin, pemetrexed, bevacizumab)Active Control8 Interventions

Patients receive bevacizumab IV over 30-90 minutes, carboplatin IV over 30 minutes, and pemetrexed IV over 10 minutes on day 1. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Within 4-8 weeks, patients undergo cytoreductive surgery and HIPEC. Patients not eligible for surgery may receive bevacizumab with or without atezolizumab at the discretion of the investigator in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan and PET scan on study. Patients also undergo blood and tissue sample collection on study.
