Key Inclusion Criteria: * Participant has histologically confirmed diagnosis of high-grade serous or high-grade endometrioid ovarian cancer, fallopian tube cancer, or primary peritoneal cancer * Measurable disease, i.e., at least one measurable lesion per RECIST 1.1 criteria (a lesion at a previously irradiated site may only be counted as a target lesion if there is clear sign of progression since the irradiation) * If no measurable disease is present, the disease should be assessable by Gynecologic Cancer Intergroup criteria (GCIC) for CA-125 * Participant has no germline BRCA1/2 mutation as determined by an FDA-approved assay * Participant has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 * Participant has platinum-resistant (progression within one to six months after completing platinum-based therapy) or platinum refractory disease (progression during treatment or within 4 weeks after the last dose), where platinum-based therapy is not an option, according to the GCIG 5th Ovarian Cancer Consensus Conference definitions (Wilson et al 2016). The platinum-based chemotherapy regimen does not necessarily need to be the last regimen the participant received prior to study entry * Participant must have received at least one but no more than three prior systemic treatment regimens and for whom single-agent chemotherapy is appropriate as the next line of treatment * Participant has received prior bevacizumab or is not eligible to receive bevacizumab due to medical reasons. Key Exclusion Criteria: * Participant has received prior treatment with any PI3K, mTOR or AKT inhibitor * Participant is concurrently using other anti-cancer therapy * Participant is in a state of small or large bowel obstruction or has other impairment of gastrointestinal (GI) function or GI disease * Participant has had surgery within 14 days prior to starting study drug or has not recovered from major adverse effects * Participant has not recovered from all toxicities related to prior anticancer therapies to baseline or NCI CTCAE Version 4.03 Grade ≤1. Exception to this criterion: participants with any grade of alopecia are allowed to enter the study * Participant has an established diagnosis of diabetes mellitus type I or uncontrolled type II based on fasting plasma glucose and HbA1c * Participants with liver impairment and Child Pugh score B or C * Participant has received radiotherapy ≤ 4 weeks or limited field radiation for palliation ≤ 2 weeks prior to randomization, and who has not recovered to baseline, grade 1 or better from related adverse effects of such therapy (with the exception of alopecia) * Participant has a known hypersensitivity to any of the study drugs or excipients * Participant has a history of myelodysplastic syndrome or acute myeloid leukemia, or presents clinical and/ or laboratory features suggestive thereof.
