A Phase 1 Study of AC220 (ASP2689) in Combination with Induction and Consolidation Chemotherapy in Patients with Newly Diagnosed Acute Myeloid Leukemia
The goal of this clinical research study is to learn the highest tolerable dose and best schedule of the combination of up to 2 cycles of Induction chemotherapy (daunorubicin, cytarabine, and AC220), up to 3 cycles of Consolidation chemotherapy (AC220 and high dose cytarabine), and then up to 12 cycles of Maintenance chemotherapy (AC220) that can be given to patients with AML. The safety of this combination of drugs will also be studied.
Disease Group: Leukemia
Treatment Agent: AC220,Cytarabine,Daunorubicin
Treatment Location: Both at MD Anderson & Other Sites
Sponsor: Astellas Pharma Global Development, Inc. (APGD)
The primary objectives are to: Describe the dose limiting toxicities (DLT) of AC220 when combined with cytarabine/daunorubicin remission induction in a 7+3 schedule. Define the maximum tolerated dose (MTD) of AC220 when combined with cytarabine/daunorubicin remission induction in a 7+3 schedule. Define the recommended Phase 2/3 dose of AC220 when given with 7+3 induction and high-dose cytarabine (HiDAC) consolidation therapy in subjects with newly diagnosed acute myeloid leukemia. Evaluate the safety and tolerability of AC220 given with 7+3 induction and high-dose cytarabine (HiDAC) consolidation therapy in subjects with newly diagnosed acute myeloid leukemia. Define the DLTs and MTD of AC220 given as maintenance following 7+3 induction and HiDAC consolidation therapy. The secondary objectives are to: Characterize the pharmacokinetics (PK) of AC220 and AC886 (pharmacologically active metabolite of AC220) when AC220 is given in combination with remission induction and consolidation therapy, and as maintenance monotherapy post consolidation in newly diagnosed acute myeloid leukemia. Evaluate the effect of AC220 on the pharmacokinetics of cytarabine, daunorubicin, and daunorubicinol (pharmacologically active metabolite of daunorubicin) when given in combination with AC220 at the MTD. The exploratory objectives are to: Evaluate the efficacy of AC220 when combined with 7+3 induction followed by HiDAC plus AC220 consolidation chemotherapy. Evaluate the pharmacodynamic effect of AC220 treatment on FMS-like tyrosine kinase (FLT3) and cKIT inhibition. Evaluate pharmacodynamic effect of AC220 treatment on FLT3 ligand and cKIT ligand/stem cell factor.
