Clinical Trial Summary

This research is being conducted to determine a safe and effective dose of revumenib that can be given in combination with standard induction (initial therapy to induce a remission) + FLT3 targeted therapy (midostaurin) and a single cycle of post-remission therapy + FLT3 targeted therapy (midostaurin) to participants with newly diagnosed Nucleophosmin (NPM1) and FMS-like tyrosine kinase 3 (FLT3) mutated Acute Myeloid Leukemia (AML).

The names of the study drugs involved in this study are:

• Revumenib (SNDX-5613) (a type of menin inhibitor)

• Midostaurin (a type of multi-kinase including FLT3 inhibitor)

• Cytarabine (a type of antineoplastic agent)

• Daunorubicin (a type of antineoplastic agent)

Description:

This is a single arm open label phase I trial of the menin inhibitor, revumenib, in combination with cytarabine and daunorubicin (7+3) chemotherapy and the multikinase inhibitor midostaurin for the frontline treatment of Nucleophosmin (NPM1) and FMS-like tyrosine kinase 3 (FLT3) mutated Acute Myeloid Leukemia (AML).

Investigators are trying to determine the highest dose of revumenib that can be given safely in combination with these chemotherapy drugs. Treatment consists of 1-2 cycles of so-called "induction treatment" (initial chemotherapy to induce a remission of the leukemia). This "induction treatment" consists of revumenib + 7+3 (7 days of cytarabine + 3 days of daunorubicin) chemotherapy + midostaurin.

The U.S. Food and Drug Administration (FDA) has not approved the combination of revumenib, cytarabine, daunorubicin, and midostaurin as a treatment for AML.

The research study procedures include screening for eligibility, study treatment visits, blood and urine tests, bone marrow biopsies, and electrocardiograms (ECGs).

Participants will receive study treatment as long as there are no serious side effects and the disease does not progress.

The trial will include up to 12 participants in dose finding phase and 10 additional participants in the dose expansion phase for a total participant number of 22 participants.

Syndax Pharmaceuticals is supporting this research study by supply revumenib (SNDX-5613).
