A Study of Ipatasertib in Combination With Paclitaxel as a Treatment for Participants With PIK3CA/AKT1/PTEN-Altered, Locally Advanced or Metastatic, Triple-Negative Breast Cancer or Hormone Receptor-Positive, HER2-Negative Breast Cancer
a study on Breast Cancer
This study will evaluate the efficacy of ipatasertib + paclitaxel versus placebo + paclitaxel in participants with histologically confirmed, locally advanced or metastatic triple-negative breast cancer (TNBC) and in participants with locally advanced or metastatic hormone receptor positive (HR+)/ human epidermal growth factor receptor 2 negative (HER2−) breast adenocarcinoma who are not suitable for endocrine therapy.

Open to people ages 18 years and up
- Women or men aged =>18 years with histologically documented triple-negative breast cancer (TNBC) or HR+/HER2- adenocarcinoma of the breast that is locally advanced or metastatic and is not amenable to resection with curative intent
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
- Adequate hematologic and organ function within 14 days prior to treatment initiation
- Histologically documented TNBC or HR+/HER2- adenocarcinoma of the breast that is locally advanced or metastatic and is not amenable to resection with curative intent
- 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
You CAN'T join if...
- 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

- 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
