Measure Type Secondary
Measure Title Duration of Response (DR)
Measure Description Time in days from the first documentation of objective tumor response to objective tumor progression or death due to any cancer. Duration of tumor response was calculated as the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1. DR was calculated for the subgroup of participants with a confirmed objective tumor response.
Time Frame Phase 2 baseline to disease progression or discontinuation from study due to any cause, assessed every 8 weeks up to 80 weeks  
Safety Issue No
