SECONDARY outcome

Timeframe: Up to 18 months

All safety analyses for AEs will be based on all subjects who receive at least 1 cycle of study treatment. AEs will be graded by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 from the initiation of study treatment until discontinuation of treatment. For each treatment-related adverse event, the number of subjects who experience at least 1 occurrence of the given event which was attributed to the study regimen as probable, possible or definite will be summarized.

DOR is defined as the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease according to the IMWG criteria or death due to progressive disease whichever occurred first all subjects who have measurable disease and received at least 2 cycles of study treatment, and have at least 2 efficacy evaluation assessments. DOR will be summarized using the Kaplan-Meier estimator. Median even-free survival will be reported and the corresponding 95% confidence interval will be calculated using Brookmeyer and Crowley method.

OS is defined as the date of first dose of study treatment to the date of death due to any cause or censored based on the date of last encounter if patient is alive or lost to follow-up. OS will be summarized using the Kaplan-Meier estimator.
