Clinical Trial Summary

A Phase 1/2a dose escalation and dose ranging study of FF-10101-01 in subjects with relapsed or refractory acute myeloid leukemia to determine the safety, tolerability, PK and preliminary efficacy. A total of 9 cohorts will be enrolled in Phase 1 to establish the Maximum Tolerated Dose (MTD). Phase 2a will consist of up to 3 dose levels (high, medium, and low) of which subjects with FLT3 mutations will randomly be assigned.

Description:

Subjects will receive FF-10101-01 orally once a day repeated every 28 days =1 cycle Frequent blood draws will be collected to measure pharmacodynamic parameters and pharmacodynamic activity.

Disease assessments, including bone marrow aspirates, will be performed at the beginning of cycles 1-3, and every 3 months thereafter. Subjects who demonstrate objective response or stable disease will be allowed to continue therapy with FF-10101-01 until , observation of unacceptable adverse events, or until the subject is no longer deriving benefit based on the opinion of the investigator.

For Phase 2a long term phone follow-up for assessment of overall survival will also occur.

Intervention

Drug:
• FF-10101-01
FF-10101-01 will be administered orally once a day on Days 1-28 of a 28-day cycle. In Phase 1, the dose escalation will proceed until MTD is reached. In Phase 2a, subjects will be randomly assigned to 1 of 3 dose levels in a balanced fashion. The treatment will continue until, intolerable toxicity, or investigation/subject decision.
