A Phase I Study to Evaluate the Safety and Tolerability of Gemtuzumab Ozogamicin and Midostaurin When Used in Combination With Standard Cytarabine and Daunorubicin Induction for Newly Diagnosed FLT3-mutated Acute Myeloid Leukemia

OSU-21190

This phase I study hopes to explore how safe and tolerable is the combination of gemtuzumab ozogamicin (GO) and midostaurin, with the standard induction therapy (cytarabine and daunorubicin) in patients with newly diagnosed FLT-3 mutated Acute Myeloid Leukemia (AML). GO is FDA approved for the treatment of adults with newly diagnosed CD33 positive AML and used in combination with chemotherapy, cytarabine and daunorubicin. Midostaurin is FDA approved for use with cytarabine and daunorubicin in patients with FLT3-mutated AML. By combining standard induction therapy with GO and midostaurin, our aim is to investigate a novel approach to treating patients with newly diagnosed FLT3-mutated AML.

Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately * Male patients of childbearing potential having intercourse with females of childbearing potential must agree to abstain from heterosexual intercourse or have their partner use 2 forms of contraception from the screening visit until 4 months following the last dose of study treatment. They must also refrain from sperm donation from the screening visit until 4 months following the last dose of study treatment Exclusion Criteria: * Isolated myeloid sarcoma (meaning, patients must have blood or marrow involvement to enter study) * Acute promyelocytic leukemia (per World Health Organization classification) * Active central nervous system (CNS) involvement by AML, as assessed at discretion of principal investigator (PI) or treating physician and confirmed by lumbar puncture * Except for hydroxyurea, no other prior systemic anti-AML therapies may have been received prior to starting study therapy * Known history of veno-occlusive disease * Known active human immunodeficiency virus (HIV), active hepatitis B or active hepatitis C infection * Patients with the following will be excluded: uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, serious cardiac arrhythmia, myocardial infarction within 6 months prior to enrollment, New York Heart Association (NYHA) class III or IV heart failure, severe uncontrolled ventricular arrhythmias * Patients with uncontrolled infection will not be enrolled until infection is treated * Any concurrent condition that, in the investigator's opinion, would jeopardize the safety of the patient or compliance with the protocol * Inability to take oral medication * Hypersensitivity to any study agent, or its excipients, when administered alone * Pregnancy or breastfeeding at the time of enrollment
