Brief summary

Randomized phase II trial to compare the efficacy and safety of standard chemotherapy plus quizartinib versus standard chemotherapy plus placebo in adult patients with newly diagnosed FLT3 wild-type Acute Myeloid Leukemia

Detailed description

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.

Interventions

DRUGQuizartinib

Induction: oral quizartinib (dose defined in safety run-in phase) 14 days (8-21) (dose will be halved with strong CYP3A inhibitor), up to 2 cycles of 35 days. Consolidation: oral quizartinib (dose defined in safety run-in phase) 14 days (6-19) (dose will be halved with strong CYP3A inhibitor), up to 4 cycles of 35 days. Maintenance: oral quizartinib 60mg/day (dose will be halved with strong CYP3A inhibitor), up to 12 cycles of 28 days.

DRUGPlacebo oral tablet

Induction: oral placebo (dose defined in safety run-in phase) 14 days (8-21) (dose will be halved with strong CYP3A inhibitor), up to 2 cycles of 35 days. Consolidation: oral placebo (dose defined in safety run-in phase) 14 days (6-19) (dose will be halved with strong CYP3A inhibitor), up to 4 cycles of 35 days. Maintenance: oral placebo 60mg/day (dose will be halved with strong CYP3A inhibitor), up to 12 cycles of 28 days.

DRUGCytarabine

Induction: Cytarabine continuous IV infusion, 200 mg/m2 (days 1-7), up to 2 cycles of 35 days. Consolidation: Cytarabine IV infusion, 1,5-3 g/m2 (days 1, 3, 5), up to 4 cycles of 35 days.

DRUGIdarubicin

Induction: Idarubicin IV infusion 12 mg/m2 (days 1-3), up to 2 cycles of 35 days.

QUADRUPLE (Subject, Caregiver, 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.

Intervention model description

Safety run-in phase: multicenter, prospective, open-label. Phase II: multicenter, prospective, randomized, placebo-controlled, double-blinded
