About this trial

This is a clinical study aiming to assess pharmacokinetics, pharmacodynamics and preliminary efficacy of ZE46-0134 in patients with FLT3 and spliceosome mutated Relapsed or Refractory Acute Myeloid Leukemia

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Written Informed Consent must be obtained from the patient or legally authorized representative prior to any study-related procedures (including withdrawal of prohibited medication, if applicable).

Patient is ≥18 years of age at the time of obtaining informed consent.

Patient is refractory to or relapsed after first-line AML therapy (with or without HSCT).

Group 1: Patient must have a confirmed FLT3-ITD or FLT3-TKD mutation by central laboratory testing. Group 2: Patient must have a documented SF3B1, SRSF2, U2AF1, or ZRSR2 pathogenic mutation by local lab sequencing.

Disqualifiers
