E.5.1.1 | Timepoint(s) of evaluation of this end point |
Safety evaluation including AEs, laboratory abnormalities and incidence of DLT: in Part A, the safety of combination treatment will be evaluated by the SMC prior to expansion of enrollment to evaluate treatment effect in Part B. After 6 patients have been followed through the end of the DLT period, or at the point that 2 or more patients experience a DLT, whichever comes first. In Part B, the SMC will continue to evaluate and monitor the safety of study drug throughout the study. It will convene as needed. - For confirmed ORR: Patients will be evaluated for response after every 2 cycles of treatment in the first 8 cycles, and after every fourth cycle thereafter. If clinically indicated, response evaluation may be preformed earlier at the discretion of the investigator. |
