Description of intervention(s) / exposure
Treatment: Drugs - Ipatasertib
Treatment: Drugs - Rucaparib

Experimental: Dose escalation-Cohort 1 - Participants with advanced breast cancer, ovarian cancer, or prostate cancer will receive ipatasertib, 300 milligrams (mg), orally, once daily (QD) for 7 days in the run-in period. Participants will then receive ipatasertib, 300 mg, orally QD, and rucaparib, 400 mg, orally twice daily (BID) in each 28-day cycle until disease progression, unacceptable toxicity, death, or participant or investigator's decision to withdraw, whichever occurs first.

Experimental: Dose escalation-Cohort 2a - Participants with advanced breast cancer, ovarian cancer, or prostate cancer will receive ipatasertib, 300 mg, orally, QD for 7 days in the run-in period. Participants will then receive ipatasertib, 300 mg, orally QD, and rucaparib, 600 mg, orally BID in each 28-day cycle until disease progression, unacceptable toxicity, death, or participant or investigator's decision to withdraw, whichever occurs first.

Experimental: Dose escalation-Cohort 2b - Participants with advanced breast cancer, ovarian cancer, or prostate cancer will receive ipatasertib, 400 mg, orally, QD for 7 days in the run-in period. Participants will then receive ipatasertib, 400 mg, orally QD, and rucaparib, 400 mg, orally BID in each 28-day cycle until disease progression, unacceptable toxicity, death, or participant or investigator's decision to withdraw, whichever occurs first.

Experimental: Dose escalation-Cohort 3 - Participants with advanced breast cancer, ovarian cancer, or prostate cancer are planned to receive ipatasertib 400 mg orally QD for 7 days (run-in period prior to Cycle 1). Participants will then receive ipatasertib 400 mg orally QD and rucaparib 600 mg, orally BID in 28 days cycle until disease progression, unacceptable toxicity, death, or participant or investigator's decision to withdraw, whichever occurs first.

Experimental: Dose Expansion - The recommended dose (ipatasertib and rucaparib) identified in Part 1 will be evaluated 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).

Summary
Brief 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).
