Triple combination with Gedatolisib (HY-10681), Palbociclib (HY-50767), and Fulvestrant (HY-13636) effectively inhibits growth of PIK3CA-mutant ER+ tumor xenografts resistant to combined palbociclib and fulvestrant. MPF-R cells (1 × 106) resistant to combined palbociclib and fulvestrant were injected into the mammary fat pads of NOG CIEA mice, and tumors were allowed to establish for 2 weeks to a size of ≈30 mm3. Mice were then treated with the combination of Fulvestrant (100 mg/kg, sc weekly), Palbociclib (25 mg/kg, oral gavage daily), and Capivasertib (100 mg/kg, oral gavage daily; n = 6) or Alpelisib (HY-15244; 25 mg/kg, oral gavage daily; n = 5). Tumor size was measured weekly. Average tumor growth curves measured weekly and Tumor volumes measured after excision.
