A Phase 1 Study of WU-NK-101 in Patients With Relapsed or Refractory (R/R) Acute Myeloid Leukemia (AML)

Allotera Therapeutics9 enrolled

Overview

This study is a Phase 1, open-label, dose escalation, and cohort expansion study designed to characterize the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary anti-leukemic activity of WU-NK-101 in R/R AML.

This is a first in human, multi-center Phase 1 single agent study in patients with R/R AML who have exhausted other treatment options. The study will consist of two phases, dose escalation and cohort expansion. During the Dose Escalation Phase, up to 18 patients will be treated with WU-NK-101 in up to 3 Dose Levels (DL) until maximum tolerated dose (MTD) or maximum administered dose (MAD) is determined. Once the MTD/MAD is defined, 6 additional patients will be enrolled in the Cohort Expansion Phase to further characterize the safety, tolerability, as well as determining the recommended phase 2 dose (RP2D) of WU-NK-101. Patients in the Cohort Expansion Phase, who achieve a partial response (PR), may receive up to 2 further re-induction cycles contingent on safety in the Dose Escalation Phase; patients who achieve a complete remission with partial hematologic recovery (CRh) or complete remission with incomplete hematologic recovery (CRi) at any point during the course of treatment may receive a further consolidation cycle, for a total of up to 4 cycles per patient. During cohort expansion, dosing breaks of up to two weeks are allowed between cycles.
