Acute Myeloid Leukemia Clinical Trial
Milademetan Plus Quizartinib Combination Study in FLT3-ITD Mutant Acute Myeloid Leukemia (AML)
Summary
Participants with AML that have gone into remission and come back (relapsed) or gone into remission with a number of leukemia cells still in their system (refractory) will be recruited for this study. They will also be positive for FLT3-ITD mutation.
Participants will receive a combined dose of quizartinib and milademetan that have not been approved by the US Food and Drug Administration yet (m).
The combination of these drugs will be provided in different amounts on defined days (dosing schedules).
It is expected that the combination of milademetan and quizartinib will be safe and well tolerated. It is expected that the combination may fight the leukemia better than a single drug.
The study will run for approximately 3 years. There may be up to 156 participants.
The study has 2 parts:
Part 1 will test 24-36 participants in approximately 15 study centers globally. Participants will receive two study drugs (milademetan and quizartinib) in different amounts on specific days. Information will be gathered to see what dosing schedule of the drug combination is best (maximum tolerated/recommended dose).
Part 2 of the study will confirm the recommended dosing schedule identified in Part 1 is effective. A larger number of participants will receive the recommended dose in approximately 15 additional sites worldwide as necessary, based on the enrollment rate, the population, and the standard of care available to them at the time of enrollment.

Part 2 (dose expansion): Has FLT3-ITD mutant (≥3% FLT3-ITD/total FLT3) AML (primary, secondary, or therapy-related AML), and has treatment failure to prior AML therapy or have relapsed after prior AML therapy, OR has newly diagnosed AML who are ineligible for intensive induction chemotherapy

Exclusion Criteria:

Has persistent, clinically significant > Grade 1 non-hematologic toxicity from prior AML therapies
Has any history or medical condition, metastatic condition, drug/medication use or other condition that might, per protocol or in the opinion of the investigator, compromise:
safety or well-being of the participant or offspring
safety of study staff
