Authorised Therapeutic confirmatory (Phase III) Metastatic Castration-sensitive Prostate Cancer

Phase 3 Randomized Study of Talazoparib with Enzalutamide in Men with DDR Gene Mutated mCSPC

EU CTIS ID: 2024-510809-28-00

What this study is testing

To demonstrate that talazoparib in combination with enzalutamide is superior to placebo in combination with enzalutamide in prolonging investigator-assessed Radiographic Progression-free Survival (rPFS), in participants with mCSPC harboring HRR deficiencies.

Who can take part

You may be able to join if

  • 1. Histologically or cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation, small cell or signet cell features
  • 2. Confirmation of DDR gene mutation status by prospective or historical analysis (with sponsor pre-approval) of blood (liquid biopsy) and/or de novo or archival tumor tissue using FoundationOne® Liquid CDx or FoundationOne® CDx
  • 3. Ongoing ADT with a gonadotropin-releasing hormone (GnRH) agonist or antagonist for participants who have not undergone bilateral orchiectomy must be initiated before randomization and must continue throughout the study
  • 4. Metastatic prostate cancer documented by positive bone scan (for bone disease) or metastatic lesions on CT or MRI scan (for soft tissue). Participants whose disease spread is limited to regional pelvic lymph nodes are not eligible. Note: a finding of superscan at baseline is exclusionary
  • 5. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.

You likely can't join if

  • 1. Other acute or chronic medical [concurrent disease, infection, including chronic stable Human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV) infection, or co-morbidity] or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that interferes with a participant’s ability to participate in the study, may increase the risk associated with study participation or study treatment administration, or may interfere with the interpretation of study results, and, in the investigator’s judgment, make the participant inappropriate for entry into the study. HIV/HBV/HCV testing is not required unless mandated by local health authority.
  • 2. History of seizure or any condition (as assessed by investigator) that may predispose to seizure
  • 3. Known or suspected brain metastasis or active leptomeningeal disease.
  • 4. Clinically significant cardiovascular disease.
  • 5. Prior treatment in any setting with NHT except prior ADT in the adjuvant/neoadjuvant setting, where the completion of ADT was less than 12 months prior to randomization and the total duration of ADT exceeded 36 months.
  • 6. Any previous treatment with DNA-damaging cytotoxic chemotherapy (ie, platinum based therapy) within 5 years prior to randomization, except for indications other than prostate cancer.
