| Acute Myeloid Leukemia | Drug: Quizartinib Drug: Placebo oral tablet Drug: Cytarabine Drug: Idarubicin | Phase 2 |
Multicenter, prospective, randomized, placebo-controlled, double-blinded phase II trial to assess the efficacy and safety of an oral quizartinib vs. placebo containing front-line chemotherapy-based schedule in FMS-like tyrosine kinase 3 internal tandem duplications (FLT3-ITD) wild-type Acute Myeloid Leukemia patients.
The trial will be conducted in two phases:
An open-label safety run-in phase: Cytarabine 200 mg/m2 (days 1-7), Idarubicin 12 mg/m2 (days 1-3) Quizartinib 60 mg/d x 14 days (30mg with strong Cytochrome P450 Family 3 Subfamily A (CYP3A) inhibitor) in a total of 9 patients, being observed during 1 cycle of induction to define the final dose for the randomized phase.
A randomized double-blinded phase 2:1 quizartinib (at the established dose) vs. placebo.
Experimental Arm: Cytarabine 200 mg/m2 (days 1-7), Idarubicin 12 mg/m2 (days 1-3) Quizartinib 60 mg/d x 14 days (30mg with strong CYP3A inhibitor) Standard Arm: Cytarabine 200 mg/m2 (days 1-7), Idarubicin 12 mg/m2 (days 1-3) Placebo 60 mg/d x 14 days (30mg with strong CYP3A inhibitor)
272 patients will be included in this phase.
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 273 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Intervention Model Description: | Safety run-in phase: multicenter, prospective, open-label. Phase II: multicenter, prospective, randomized, placebo-controlled, double-blinded |
| Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
| Masking Description: | Subjects will be randomized into 1 of the 2 treatment groups (quizartinib or placebo) in a 2:1 ratio. The randomization will be stratified by age (<60 vs. ≥60 years old) at the time of diagnosis of AML. Neither the subjects nor any of the Investigators, Sponsor, or contract research organizations (CROs) will be aware of the treatments received. An independent biostatistician, not otherwise part of the study team, will generate the randomization schedule. |
