About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • WU-NK-101Biological

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

Study groups in NCT05470140
Study groupRoleWhat they receive
Experimental: WU-NK-101ExperimentalA 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.
Receives: Biological: WU-NK-101

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 24 months

  2. Maximum Tolerated Dose

    Maximum Tolerated or Administered Dose of WU-NK-101

    Measured: Up to 21 days from first dose

Secondary outcomes (3)
  1. Overall Survival

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

    Measured: 3 months

  2. Duration of Response

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

    Measured: 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).

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing WU-NK-101 in people with Acute Myeloid Leukemia, run by Allotera Therapeutics at 9 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Adverse Events of WU-NK-101 as assessed by CTCAE v5 (time frame: 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025.
