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.

               1. No standard care available

               2. PLD at the dose and schedule being used might be considered standard of care

               1. Participants with histologically confirmed advanced primary endometrial cancer
                  (locally advanced and incurable endometrial cancer that had been treated with
                  surgery and/or radiation or is ineligible for such treatment), or recurrent or
                  metastatic endometrial cancer, and
