- Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
- Eligible for taxane monotherapy, as per local investigator assessment (e.g., absence of rapid clinical progression, life-threatening visceral metastases, or the need for rapid symptom and/or disease control which may require combination chemotherapy)
- HR+/HER2- breast cancer that is not considered appropriate for endocrine-based therapy and meets one of the following: patient has recurrent disease \<=5 years of being on adjuvant endocrine therapy or if patient with de novo metastatic disease have progressed within 6 months of being on first line endocrine therapy.
- Consent to submit a formalin-fixed, paraffin-embedded tumor (FFPE) tissue block or freshly cut unstained, serial tumor slides from the most recently collected tumor tissue for central molecular analysis
- Confirmation of biomarker eligibility using an appropriately validated molecular assay at a diagnostic laboratory, Clinically Laboratory Improvement Amendments (CLIA) or equivalently accredited i.e., valid results from either central testing or local testing of tumor tissue or blood demonstrating PIK3CA/AKT1/PTEN-altered status
- For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception and agreement to refrain from donating eggs
- For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods and agreement to refrain from donating sperm
Exclusion
- Treatment with approved or investigational cancer therapy within 14 days prior to treatment initiation
- Any previous chemotherapy for inoperable locally advanced or metastatic TNBC or HR+/HER2- adenocarcinoma of the breast (patients receiving neo/adjuvant chemotherapy eligible provided they have at least a 12 month disease-free interval)
- History of or known presence of brain or spinal cord metastases
- Malignancies other than breast cancer within 5 years prior to treatment initiation (except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or Stage I uterine cancer)
- Prior treatment with an Akt inhibitor (prior PI3K or mTOR inhibitors are allowed)
- History of malabsorption syndrome or other condition that would interfere with enteral absorption or results in the inability or unwillingness to swallow pills
- Active infection requiring systemic anti-microbial treatment (including antibiotics, anti-fungals, and anti-viral agents)
- Known human immunodeficiency virus (HIV) infection
- Known clinically significant history of liver disease consistent with Child-Pugh Class B or C, including active viral or other hepatitis, current drug or alcohol abuse, or cirrhosis

- Pregnant or breastfeeding, or intending to become pregnant during the study
- Clinically significant cardiac dysfunction (including NYHA Class II/III/IV heart failure, left ventricular ejection fraction \[LVEF\] \<50%, active ventricular arrhythmia requiring medication, history of myocardial infarction within 6 months of treatment initiation, clinically significant electrocardiogram \[ECG\] abnormalities).
- Need for chronic corticosteroid therapy of \>=10 mg of prednisone per day or an equivalent dose of other anti-inflammatory corticosteroids or immunosuppressants for a chronic disease
- Unresolved, clinically significant toxicity from prior therapy, except for alopecia and Grade 1 peripheral neuropathy
- Uncontrolled clinical symptoms including pleural effusion, pericardial effusion, or ascites, tumor-related pain, hypercalcemia (or symptomatic hypercalcemia requiring continued use of bisphosphonate therapy)
- History of Type I or Type II diabetes mellitus requiring insulin
- Grade \>=2 uncontrolled or untreated hypercholesterolemia or hypertriglyceridemia
- History of or active inflammatory bowel disease or active bowel inflammation
- Clinically significant lung disease (including pneumonitis, interstitial lung disease, idiopathic pulmonary fibrosis, cystic fibrosis, active infection/ history of opportunistic infections)
- Treatment with strong CYP3A inhibitors or strong CYP3A inducers within 2 weeks or 5 drug-elimination half-lives, whichever is longer, prior to initiation of treatment
- Grade \>=2 peripheral neuropathy
