Study summary

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.

Read the detailed description

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.

Study arms

  • Experimental
    Experimental: WU-NK-101

    A non-engineered Natural Killer (NK) cell derived from peripheral blood mononuclear cells (PBMC) that is cytokine-reprogrammed, expanded, and cryopreserved to create an allogeneic enhanced Memory-like anti-tumor NK cell therapy product. Each 28-day cycle of treatment consists of 3 doses of WU-NK-101 administered on Day 1, Day 8, and Day 15.

    Biological: WU-NK-101

Interventions

  • BiologicalWU-NK-101

    WU-NK-101 administered on Day 1, Day 8, and Day 15.

What researchers measure

Primary outcomes

  1. Incidence of Adverse Events of WU-NK-101 as assessed by CTCAE v5

    Safety is based on evaluation of adverse events (AEs) and serious adverse events (SAEs) from the time of consent until End of Study (EOS) visit.

    Time frame: 24 months

  2. Maximum Tolerated Dose

    Maximum Tolerated or Administered Dose of WU-NK-101

    Time frame: Up to 21 days from first dose

Secondary outcomes

  1. Overall Survival

    Time from study drug administration (Day 1) until death on study.

    Time frame: 3 months

  2. Duration of Response

    Time of response to the time of disease relapse, progression, or death due to any cause.

    Time frame: 24 months

  3. Overall Response Rate (ORR)

    ORR is defined as proportion of patients that achieve complete remission (CR) + complete remission with incomplete hematologic recover (CRi).

    Time frame: 24 months
