      Trial Summary

      This is a study in participants with advanced breast, ovarian, or prostate cancer to investigate the dose, safety, pharmacokinetics, and preliminary efficacy of ipatasertib in combination with rucaparib. The study consists of two parts: a Dose-Escalation Phase (Part 1) in participants with previously treated advanced breast cancer, ovarian cancer, or prostate cancer and a Dose-Expansion Phase (Part 2) in participants with advanced prostate cancer who have had at least one line of prior therapy with second-generation androgen-receptor (AR)-targeted agents (e.g., abiraterone, enzalutamide, apalutamide).

Cytologic or fine needle aspirate samples are not acceptable. Tumor tissue from bone metastases is not acceptable.
      • For men and women of child bearing potential: agreement to remain abstinent or use protocol defined contraceptive measures during the treatment period and for at least 28 days after the last dose of ipatasertib,or 6 months after the last dose of rucaparib, whichever occurs later

      • History of clinically significant cardiovascular dysfunction
      • Presence of any other condition that may have increased the risk associated with study participation or may have interfered with the interpretation of study results, and, in the opinion of the investigator, would have made the patient inappropriate for entry into the study
