What was measured

Recommended Phase 2 dose was determined by maximum tolerated dose (MTD). MTD was defined as the next lower dose level below the one in which \> 1 of 3 participants or ≥ 2 of 6 participants experienced dose-limiting toxicity (DLT), provided that that dose level is ≤25% lower than the highest dose tested. If the projected MTD was \>25% lower than the highest dose tested, then an additional cohort of ≥3 participants were added at a dose that was intermediate between the intolerable dose and the next lower dose.

Analysis population: Efficacy analysis set included all participants who had either completed 1 cycle of treatment or discontinued treatment prior to completing the first cycle due to documented progressive disease (PD), death related to disease, or treatment-related toxicity. Here, data was not planned and analyzed based on individual specific disease, hence overall data was analyzed for this outcome measure.
