  • Male subjects and their female partner who are of child-bearing potential (as defined in Inclusion 10), and are not practicing total abstinence, must agree to use two forms of highly effective contraception from the last menstrual period of their female partner prior to randomization (or use a double barrier method as described above until they are on two forms of highly effective contraception for at least one menstrual cycle), during study treatment, and for 3 months (or 6 months if they received dacarbazine) after the final dose of study treatment. If currently abstinent, must agree to use a double barrier method of contraception if they become sexually active, or until they are on two forms of highly effective contraception as described above.
  • Voluntary agreement to provide written informed consent and the willingness and ability to comply with all aspects of the protocol.
  • Males or females aged greater than or equal to 18 years at the time of informed consent.

Primary outcomes

  1. Overall Survival (OS)

    Time frame: From date of treatment start until date of death from any cause, up to 5 years 5 months

    OS was defined as the time in months from the date of treatment start until death, regardless of cause. In the absence of confirmation of death, participants were censored either at the date that participant was last known to be alive or the date of study cut-off, whichever was earlier. Participants who died on the date of randomization had a survival time of 0.5 day. Allocation of randomization numbers were performed based upon the following stratification factors: (a) Histology (adipocytic [ADI] or leiomyosarcoma [LMS]), (b) Region (Region 1: USA and Canada; or Region 2: Western Europe, Australia, Israel; or Region 3: Eastern Europe, Latin America, and Asia), and (c) Number of prior regimens for advanced soft tissue sarcoma (STS) (2 or greater than [>] 2 prior regimens).

Secondary outcomes

  1. Progression-Free Survival (PFS)

    Time frame: Randomization (day 1) to the date of first documentation of disease progression, or date of death (whichever occurred first), up to 5 years 5 months

    PFS was defined as the time from the date of randomization to the date of first documentation of disease progression, or date of death (whichever occurred first). The date of disease progression was defined as the date of radiologic disease progression as assessed by the investigator or designee based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. Participants who did not have an event (i.e., participants who were lost to follow-up or who did not progress or die at the date of data cut-off), were censored. Participants who discontinued study treatment without disease progression were censored on the date of their last radiological assessment (scan date).

  2. Progression-Free Rate at 12 Weeks (PFR12wks)

    Time frame: From date of randomization start until Week 12

    The PFR12wks was defined as the percentage of participants who were still alive without disease progression at 12 weeks from the date of randomization. Tumor assessment by the investigator or designee was based on RECIST criteria 1.1.

  3. Clinical Benefit Rate (CBR)

    Time frame: From date of treatment start (Day 1) until disease progression, development of unacceptable toxicity, withdrawal of consent, participant's choice to stop study treatment, up to 5 years 5 months

    CBR was defined as the percentage of participants who have best overall response (BOR) of complete response (CR), or partial response (PR), or duration of stable disease (dSD) greater than or equal to 11 weeks, between Arm A and Arm B. CBR was estimated by treatment arm based on the tumor response evaluation performed by the PI or designee according to RECIST 1.1. CR was defined as disappearance of all target lesions. PR was defined as at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of the longest diameter.
