Study Details

Study Description

Brief Summary

This study will evaluate the efficacy and safety of atezolizumab in combination with bevacizumab in patients with unresectable locally advanced or metastatic mucosal melanoma.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

The study is divided into 2 stages. Stage I of the study is completed when 22 patients with measurable disease have been enrolled and completed ORR evaluation. If the number of responders in Stage I is more than 3, another 16 patients may be enrolled to Stage II.

  • Outcome Measures

    Primary Outcome Measures

    1. Objective Response Rate (ORR) [Up to approximately 33 months]

      ORR is defined as the proportion of patients with a complete response (CR) or partial response (PR) on two consecutive occasions >= 4 weeks apart, as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1).

    Secondary Outcome Measures

    1. Progression-Free Survival (PFS) [Up to approximately 33 months]

      PFS is defined as the time from the date of first treatment to the first occurrence of disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1.

    2. Overall Survival (OS) [Up to approximately 33 months]

      OS is defined as the time from the date of first treatment to death from any cause.

    3. Duration of Objective Response (DOR) [Up to approximately 33 months]

      DOR is defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1

    4. Disease Control Rate (DCR) [Up to approximately 33 months]

      DCR is defined as the sum of a complete or partial response or stable disease rates as determined by the investigator according to RECIST v1.1.

    5. Percentage of Participants With Adverse Events [Up to approximately 33 months]
