Brief summary
A Phase 1/2a Dose Escalation Study of FF-10501-01 in Patients with Relapsed or Refractory Hematological Malignancies to determine the safety and tolerability. A total of 6 cohorts will be enrolled in Phase 1 to establish the MTD. A total of 20 subjects with MDS/CMML treated at the RP2D are planned, including MDS/CMML subjects treated at the RP2D in Phase 1.
Detailed description
Subjects will receive FF-10501-01 orally on a twice daily schedule for 14, 21 or 28 days repeated every 28 days (=1 cycle). Disease assessments, including analysis of blood and bone marrow aspirates, will be performed at the end of Cycle 1 and every 2 cycles thereafter. Subjects who demonstrate objective response or stable disease will be allowed to continue therapy with FF-10501-01 until progression of disease, observation of unacceptable adverse events, intercurrent illness or changes in condition that prevent further study participation.
Interventions
FF-10501-01 will be administered orally on Days 1-14 of a 28-day cycle (Cohorts 1-6), Days 1-21 of a 28-say cycle (Cohort 7), Days 1-28 of a 28-day cycle (Cohort 8) or Days 1-21 of a 28-say cycle (Cohort 9). The dose-escalation will proceed until Maximum Tolerated Dose (MTD) is reached. The treatment will continue until disease progression, intolerable toxicity or investigation/subject decision.

Determination of Objective Response (OR) Rates.
The OR endpoint: proportion of subjects w/ OR as best response (CR, CRi or PR) assessed at the end of Cycles 1 and 3. AML: CR - free of all symptoms related to leukemia, absolute neutrophil count \> 1.0 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, normal bone marrow with \< 5% blasts no Auer rods; CRi - CR with residual thrombocytopenia (platelet count \< 100 x 10\^9/L) or residual neutropenia (absolute neutrophil count \< 1.0 x 10\^9/L); PR - A ≥ 50% decrease in bone marrow blasts to 5 to 25% abnormal. MDS or CMML: CR - free of all symptoms related to leukemia, absolute neutrophil count ≥ 1.0 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, bone marrow ≤ 5% myeloblasts, w/ normal maturation of all cell lines, hemoglobin ≥ 11g/dL, no blasts in the peripheral blood; PR - All CR criteria with ≥50% decrease in bone marrow blasts over pre-treatment (but still \> 5%); Marrow CR - In bone marrow, ≤ 5% myeloblasts and decrease by ≥ 50% over pre-treatment.
Time frame: OR responses were assessed at end of Cycles 1 thru 3. Each cycle was 28 days in length.
