Brief summary

The purpose of this study was to evaluate the safety and tolerability of VX-984 (M9831) administered alone and in combination with pegylated liposomal doxorubicin (PLD), and to determine the maximum tolerated dose (MTD) and preliminary evidence of efficacy of VX-984 in combination with PLD in participants with advanced solid tumors.

Part A: Number of Participants With Best Overall Response Evaluated by Response Criteria Evaluation (RECIST 1.1)

The best overall response was defined as the number of participants who had achieved complete response (CR) or partial response (PR) as the best overall response according to radiological assessments as adjudicated by the IRC from randomization until the first occurrence of progressive disease (PD). CR: Complete Response (CR) defined as disappearance of all target and non-target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm. Partial response (PR) defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameters. PD defined as an increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters of target lesions recorded since treatment started.

Time frame: Up to 2 years

Population: Full analysis set included all participants who had received at least 1 dose of the study treatment.
