Clinical Trial 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.

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.

• Prior allogeneic stem cell or solid organ transplantation

• Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications

Outcome

Primary	Objective Response Rate (ORR)	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).	Up to approximately 33 months
Secondary	Progression-Free Survival (PFS)	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.	Up to approximately 33 months
Secondary	Overall Survival (OS)	OS is defined as the time from the date of first treatment to death from any cause.	Up to approximately 33 months
Secondary	Duration of Objective Response (DOR)	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	Up to approximately 33 months
Secondary	Disease Control Rate (DCR)	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.	Up to approximately 33 months
Secondary	Percentage of Participants With Adverse Events		Up to approximately 33 months
