A Phase Ib, Open-Label, Multicenter Study Evaluating the Safety and Efficacy of Ipatasertib in Combination With Rucaparib in Patients With Advanced Breast, Ovarian, or Prostate Cancer

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).

There are two parts in the study. A Dose-Escalation Phase (Part 1) in participants with
previously treated advanced breast cancer, ovarian cancer, or prostate cancer. There will be
a 7-day run-in period with ipatasertib alone prior to Cycle 1, Day 1. After the completion of
the ipatasertib run-in period, participants will begin Cycle 1, Day 1 of the ipatasertib and
rucaparib combination treatment. Each cycle has 28 days. Participants will be split into 4
cohorts: Dose Level 1 group - 300 mg ipatasertib once daily (QD) + 400 mg rucaparib twice
daily (BID), Dose Level 2a: 300 mg ipatasertib QD + 600 mg rucaparib BID, Dose Level 2b: 400
mg ipatasertib QD + 400 mg rucaparib BID, Dose Level 3: 400 mg ipatasertib QD + 600 mg
rucaparib BID

A Dose-Expansion Phase (Part 2) - The recommended dose identified in Part 1 (highest dose
level of ipatasertib and rucaparib with an acceptable safety profile and less than one-third
of participants experience a dose limiting toxicity) 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).

with curative intent

- For patients with ovarian cancer (Part 1 only):

- For patients with breast cancer (Part 1 only): must be human epidermal growth factor
receptor 2 negative (HER2-) (estrogen receptor [ER]/progesterone positive or
negative):

1. ER/progesterone-positive patients must have received and progressed on at least
one endocrine therapy (adjuvant or metastatic)

2. ER/progesterone-negative/HER2- (triple-negative breast cancer [TNBC]) patients
