About PIKTOR

PIKTOR is an investigational, proprietary, all-oral combination of serabelisib, a selective PI3K-alpha inhibitor, and sapanisertib, an mTORC1/mTORC2 inhibitor, designed to inhibit multiple nodes of the PI3K/AKT/mTOR pathway, also known as the PAM pathway. This multi-node approach is designed to address the signaling feedback reactivation and treatment-emergent resistance mutations that may limit the efficacy of single-node PI3K/AKT/mTOR pathway inhibitors. According to published literature, the PAM pathway is dysregulated in up to 50% of all solid tumors, making it one of the most prevalent therapeutic targets in oncology.

PIKTOR is being evaluated in a Phase 2 trial in second-line advanced endometrial cancer (Study FTH-PIK-201). PIKTOR is also being evaluated in a Phase 1b/2 trial in HR+/HER2- advanced breast cancer (Study FTH-PIK-101), in which the first patient was dosed in April 2026 and interim data is anticipated in 2027.
