  • Women of childbearing potential (WOCBP) and men able to father a child must be ready and able to use two medically acceptable methods of birth control per ICH M3 (R2) that result in a low failure rate of \<1% per year when used consistently and correctly beginning at screening, during study participation, and until 6 months and 12 days after last dose for women and 102 days after last dose for men. A list of contraception methods meeting these criteria is provided in the patient information
  • Histologically documented locally advanced or metastatic, unresectable (i.e. surgery morbidity would outweigh potential benefits), progressive or recurrent Dedifferentiated liposarcoma (DDLPS), meeting the criteria for an open study cohort:
  • Cohort A: patient has not received prior systemic therapy for DDLPS in any setting (including adjuvant, neoadjuvant, maintenance, palliative)
  • Cohort B: patient has received any prior systemic therapy for DDLPS in any setting (including adjuvant, neoadjuvant, maintenance, palliative)
  • Written pathology report indicating the diagnosis of DDLPS with positive MDM2 immunohistochemistry or MDM2 amplification as demonstrated by fluorescence in situ hybridisation (FISH) or next-generation sequencing (NGS)
  • Presence of at least 1 measurable target lesion according to RECIST version 1.1. In patients who only have 1 target lesion, the baseline imaging must be performed at least 2 weeks after any biopsy of the target lesion
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

  • Previous treatment in study 1403-0008 (Brightline-1)
  • Having to receive, or intending to receive, restricted medications or any drug considered likely to interfere with the safe conduct of the study
