Atezolizumab and Bevacizumab in Treating Patients With Rare Solid Tumors

NCT03074513

Description:

This phase II trial studies how well atezolizumab and bevacizumab work in treating patients with rare solid tumors. Immunotherapy with monoclonal antibodies, such as atezolizumab and bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Purpose

This phase II trial studies how well atezolizumab and bevacizumab work in treating patients with rare solid tumors. Immunotherapy with monoclonal antibodies, such as atezolizumab and bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To evaluate the efficacy of atezolizumab when given in combination with bevacizumab (atezo
      bev).

      SECONDARY OBJECTIVES:

      I. To evaluate the efficacy of atezo bev. II. To evaluate the safety of atezo + bev.

      EXPLORATORY BIOMARKER OBJECTIVES:

      I. To identify biomarkers that are predictive of response to atezo bev (i.e., predictive
      biomarkers), are associated with progression to a more severe disease state (i.e., prognostic
      biomarkers), are associated with resistance to atezo bev, are associated with susceptibility
      to developing adverse events, can provide evidence of study treatment activity, or can
      increase the knowledge and understanding of disease biology.

      OUTLINE:

      Patients receive atezolizumab and bevacizumab intravenously (IV) over 60 minutes on day 1.
      Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

      After completion of study treatment, patients are followed up every 3 months.

Primary Outcome Measures

Measure:Objective response
Time Frame:Up to 4 years
Safety Issue:
Description:Will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (modified RECIST for pleural mesothelioma). Will be defined as a complete response or partial response on two consecutive occasions 4 weeks apart as determined by an independent radiologist. For each tumor group, the best response rate and its 95% exact confidence interval will be estimated using the Clopper and Pearson method. The combination treatment will be assessed by performing the independent binomial test comparing the best response rate versus the historical control for each tumor group. The Bayesian classification and information sharing method proposed by Lee and Chen may be applied.

Secondary Outcome Measures

Measure:Objective response
Time Frame:Up to 4 years
Safety Issue:
Description:Will be assessed by immune-modified RECIST

Time Frame:The time from enrollment to the first occurrence of disease progression or death from any cause, whichever occurs first, assessed up to 4 years
Safety Issue:
Description:Will be assessed by RECIST 1.1 (modified RECIST for pleural mesothelioma). Will be estimated using Kaplan-Meier method. The log-rank test will be performed to test the difference in time-to-event distributions between patient groups. Cox proportional hazards model may be utilized to include multiple covariates in the time-to-event analysis.
Measure:Duration of response
Time Frame:The time from the first occurrence of a documented objective response to disease progression or death from any cause, whichever occurs first, assessed up to 4 years
Safety Issue:
Description:Will be assessed by RECIST 1.1 (modified RECIST for pleural mesothelioma). For each tumor group the median duration of response and corresponding 2-sided 95% confidence interval will be reported.
