ft-1101 ...Study Participants
94This is an open-label, multicenter, dose-escalation Phase 1/1b study in patients with acute myelogenous leukemia (AML)/MDS or non-Hodgkin Lymphoma (NHL), intended to investigate safety, pharmacokinetics, and the pharmacodynamic effects of FT-1101 administered via one or more intermittent dosing schedules alone and in combination with azacitidine. Once the MTD has been established for a treatment cohort, up to 20 additional patients may be enrolled in up to 4 expansion cohorts each of select populations of patients with either AML/MDS or NHL at the recommended dose for future studies to confirm safety.
FT-1101 will be supplied as 5 mg, 20 mg or 100 mg capsules and will be administered per the protocol defined frequency and dose level
Azacitidine will be administered per site's standard of care
Following a 3+3 dose escalation strategy, the first cohort of patients will be administered FT-1101 at 10 mg, oral capsules, once weekly on a continuous basis. Subsequent cohorts dose and frequency will be determined by investigators and sponsor following observations of previous cohorts. Dose escalation will continue until the MTD is determined.
Once the MTD is determined, the Recommended Phase 2 Dose (RP2D) will be identified. 3 Expansion cohorts of up to 20 patients each will be treated with the RP2D of FT-1101
Following a 3+3 dose escalation strategy, the first cohort of AML/MDS patients will be administered FT-1101 at approximately 50% or lower than the MTD identified for the single agent FT-1101. Subsequent cohorts dose will be determined by investigators and sponsor following observations of previous cohorts. Dose escalation will not exceed the dose determined to be the single agent MTD for that schedule.
Once the MTD is determined, the Recommended Phase 2 Dose (RP2D) will be identified. 1 Expansion cohorts of up to 20 AML/MDS patients each will be treated with the RP2D of FT-1101 in combination with azacitidine.
