In this trial, ziftomenib, a menin-MLL(KMT2A) inhibitor, will be tested in patients for the first time. The trial includes a Main Study and four sub-studies. In the Main Study (including Phase 1a, Phase 1b, and Phase 2 portions), ziftomenib will be evaluated in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML). The main study has completed enrollment. In Sub-studies 1 and 2, the effects of taking ziftomenib and other common drugs at the same time will be investigated in AML patients. In Sub-study 3, ziftomenib will be evaluated in patients with R/R acute lymphoblastic leukemia (ALL). In Sub-study 4, ziftomenib will be evaluated in patients with R/R AML with certain genetic mutations.

Full study description
- brief Summary
- In this trial, ziftomenib, a menin-MLL(KMT2A) inhibitor, will be tested in patients for the first time. The trial includes a Main Study and four sub-studies. In the Main Study (including Phase 1a, Phase 1b, and Phase 2 portions), ziftomenib will be evaluated in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML). The main study has completed enrollment. In Sub-studies 1 and 2, the effects of taking ziftomenib and other common drugs at the same time will be investigated in AML patients. In Sub-study 3, ziftomenib will be evaluated in patients with R/R acute lymphoblastic leukemia (ALL). In Sub-study 4, ziftomenib will be evaluated in patients with R/R AML with certain genetic mutations.
- detailed Description
- This first-in-human (FIH), open-label study will assess ziftomenib, a menin-MLL(KMT2A) inhibitor, in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML). The trial includes a Main Study and four sub-studies. The Main Study is a Phase 1/2 dose-escalation and dose-validation/expansion study to assess ziftomenib in patients with R/R AML. The dose-escalation part of the study (Phase 1a) will determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D). The dose-validation/expansion part of the study (Phase 1b) will determine the safety, tolerability, and minimal biologically effective dose (MBED) of ziftomenib in biomarker-specific dosing cohorts from among doses that demonstrated early biological activity and are determined to be safe in the dose-escalation phase. The Phase 2 portion of the study will determine the safety, tolerability, and anti-leukemia activity of ziftomenib in patients with nucleophosmin 1-mutant (NPM1-m) AML. In Sub-study 1, the effects of co-administration of ziftomenib on the pharmacokinetics (PK) of midazolam will be studied in patients with R/R AML with certain genetic mutations. In Sub-study 2, the effects of co-administration of itraconazole on the PK of ziftomenib will be studied in patients with R/R AML with certain genetic mutations. In Sub-study 3, the safety, tolerability, and MBED/RP2D of ziftomenib will be studied in patients with R/R KMT2A-rearranged (KMT2A-r) ALL (Phase 1a dose escalation). These parameters will be investigated further for the RP2D in a Phase 1b dose-validation/cohort expansion part of the sub-study. In Sub-study 4, the clinical activity of ziftomenib will be studied in patients with R/R AML with certain genetic mutations.
