A Study of ASP2215 (Gilteritinib), Administered as Maintenance Therapy Following Induction/Consolidation Therapy for Subjects With FMS-like Tyrosine Kinase 3 (FLT3/ITD) Acute Myeloid Leukemia (AML) in First Complete Remission

Official Title

A Phase 3 Multicentre, Randomized, Double-Blind, Placebo-Controlled Trial of the FLT3 Inhibitor Gilteritinib (ASP2215) Administered as Maintenance Therapy Following Induction/Consolidation Therapy for Subjects With FLT3/ITD AML in First Complete Remission

Summary:

The purpose of this study is to compare relapse-free survival (RFS) between subjects with FMS-like tyrosine kinase 3 (FLT3) / internal tandem duplication (ITD) acute myeloid leukemia (AML) in first complete remission (CR1) and who are randomized to receive gilteritinib or placebo beginning after completion of induction/consolidation chemotherapy for a two-year period.

Trial Description

Primary Outcome:

  • Relapse-free Survival (RFS)
Secondary Outcome:
  • Overall Survival (OS)
  • Event-free survival (EFS)
  • Minimal Residual Disease (MRD)
  • Safety assessed by Adverse Events (AEs)
  • Number of participants with abnormal laboratory values and/or adverse events related to treatment
  • Number of participants with abnormal vital signs and/or adverse events related to treatment
  • Safety assessed by electrocardiograms (ECGs)
  • Number of participants with physical exam abnormalities and/or adverse events related to treatment
  • Eastern Cooperative Oncology Group (ECOG) performance status score
Subjects in CR1 will be approached for this study after induction/consolidation therapy is complete and a decision not to proceed with transplantation is made or a suitable donor could not be identified. Subjects will be randomized in a 2:1 ratio to receive gilteritinib or placebo. Subjects will enter the screening period up to 14 days prior to the start of treatment. Subjects will be administered treatment over continuous 28-day cycles. After treatment discontinuation, subjects will have a 30-day follow-up visit for safety, after which the subjects will enter the long-term follow up period for collection of subsequent AML treatment, remission status, and survival (cause of death and date of death). Gilteritinib or placebo will be given daily for up to 2 years. Subjects will be followed for up to 3 years from the subjects 30-day follow up, or until 80% of the subjects have an RFS event, whichever comes first. Study drug will not be provided during the follow-up period.
