Brief summary public domain (ClinicalTrials.gov)
Dose escalation part: to determine the highest dose of alpelisib administered on a daily basis when given in combination with daily everolimus or in combination with daily everolimus and exemestane. Dose expansion part: To describe safety and tolerability of the alpelisib and everolimus or alpelisib, everolimus and exemestane combinations.
Detailed description public domain (ClinicalTrials.gov)
The main purpose of the study was to determine the maximum tolerated dose/recommended dose for expansion (MTD/RDE) of alpelisib in combination with everolimus, and of alpelisib in combination with everolimus and exemestane, and additionally to describe safety, preliminary efficacy and the magnitude of the alpelisib-everolimus interaction. The study was conducted in patients with metastatic and/or recurrent solid tumors including renal cell carcinoma (RCC), pancreatic neuroendocrine tumor (pNET), and advanced solid tumors previously treated with an mTOR inhibitor, to evaluate everolimus and alpelisib, and in postmenopausal females with HR-positive HER2-negative advanced breast cancer to evaluate everolimus, alpelisib and exemestane. This was a Phase Ib, open-label, multi-center, dose-finding study. The initial dose level of alpelisib was 300 mg every day (qd) and everolimus was initially administered at 2.5 mg qd. The dose-finding study (escalation phase) was followed by an expansion phase where safety and preliminary efficacy of the doublet (alpelisib and everolimus) as well as of the triplet (alpelisib, everolimus and exemestane) were assessed in selected subject populations. Alpelisib, everolimus and exemestane were administered orally once daily on a continuous dosing schedule and dosed on a flat-fixed dose and not by body weight or body surface area, starting on Day 1 in a 28-day cycle. In the doublet escalation phase, alpelisib was administered at 300 mg or 250 mg in combination with 2.5 mg everolimus. In the triplet escalation phase, alpelisib was administered at 200 mg in combination with 2.5 mg everolimus and 25 mg exemestane. In the doublet expansion phase, alpelisib was administered at 250 mg in combination with 2.5 mg everolimus. In the breast cancer expansion phase, alpelisib was administered at 200 mg in combination with 2.5 mg everolimus and 25 mg exemestane or alpelisib was administered at 250 mg in combination with 25 mg exemestane. No fixed treatment duration was specified. Patients in the study were planned to receive the treatment until disease progression (assessed by Response Evaluation Criteria in Solid Tumors (RECIST v1.1)), unacceptable toxicity, death, or discontinuation from study treatment for any other reason.
