Study Endpoints
Primary Endpoints
Objective response rate (ORR)
Within 8 weeks after completion of treatment

Defined as the percentage of participants having an objective response (complete response \[CR\] or partial response \[PR\]), according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. The ORR of the drug will be assessed according to Simon's two stage design. The estimated ORR will be compared to the response rate specified in the null hypothesis (6%) using one-sided exact binomial test at type I error 5%. 95% confidence interval (C.I.) will be also reported.

Incidence of adverse events
Up to 2 years after completion of treatment

Will be determined by the number, frequency, duration, and severity of adverse events (AEs) using Common Terminology Criteria for Adverse Events (CTCAE) v 5.0; laboratory tests and vital signs.

Secondary Endpoints
Progression free survival (PFS)
From the start of therapy until disease progression, or death due to any cause, assessed up to 2 years after completion of treatment
Overall survival (OS)
From the start of therapy until death due to any cause, assessed up to 2 years after completion of treatment
Duration of Response (DOR)
Up to 2 years after completion of treatment
