Study of Safety and Efficacy of Alpelisib With Everolimus or Alpelisib With Everolimus and Exemestane in Advanced Breast Cancer Patients, Renal Cell Cancer and Pancreatic Tumors

"alpelisib is administered orally once a day on a continuous dosing schedule and dosed on a flat-fixed dose and not adjusted by body weight or body surface area, starting on Day 8 of Cycle 1 in the dose escalation and Day 1 of Cycle 1 in the dose expansion.~In the doublet dose escalation, the alpelisib starting dose is 300 mg. The alpelisib dose may be escalated or de-escalated, as needed.~In the triplet dose escalation part, the alpelisib starting dose is one dose level lower of the MTD as determined during the doublet escalation. The alpelisib dose may be escalated or de-escalated, as needed.~In the doublet dose expansion and triplet dose expansion (patients assigned to alpelisib, everolimus and exemestane), alpelisib is administered at the recommended dose determined in the dose escalation.~In the triplet dose expansion (patients assigned to alpelisib and exemestane), alpelisib is administered at a dose of 250 mg daily."

"everolimus is administered orally once a day on a continuous dosing schedule and dosed on a flat-fixed dose and not adjusted by body weight or body surface area, starting on Day 1 of cycle 1 in both the dose escalation and dose expansion parts.~In the dose escalation part, the everolimus starting dose is 2,5 mg. In the dose expansion part, everolimus is administered at the recommended dose determined in the dose escalation."

exemestane is administered orally once a day on a continuous dose of 25 mg starting on Day 1 of Cycle 1 in both the dose escalation and dose expansion.
