About This Trial

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Acute Myeloid Leukemia, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 20 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - Of age ≥ 2 years of age at the time of study enrollment - With AML diagnosed per 2016 WHO criteria (11) - With relapsed or refractory AML in their bone marrow - Refractory disease: Patients must have ≥ 5% blasts in the bone marrow after 2 courses of intensive induction treatment - Relapsed disease: Patients must have ≥ 5% blasts in the bone marrow, or reappearance of blasts in the blood, within 6 months of initial CR - With available haploidentical related donors. Donor specific antibody (DSA) testing will be done on the recipient prior to or upon enrollment. - With performance level of ≥ 50% on Karnofsky scale for patients \> 16 years of age and ≥ 50% on Lansky scale for patients ≤ 16 years of age Who Should NOT Join This Trial: - Disease: isolated central nervous system (CNS) disease, or isolated extramedullary disease, or diagnosis of acute promyelocytic leukemia (APML). Patients with extramedullary disease in combination with bone marrow disease are eligible for enrollment. - Infectious Disease: Active uncontrolled infection - Cardiac function: Systolic ejection fraction \<45% by echocardiogram - Pulmonary Function: Oxygen saturation \<92% on room air - Hepatic function: Total bilirubin \> 2mg/dL, AST and ALT more than three times the upper limit of normal - Concomitant medications: receiving either \>10mg prednisone equivalent daily, or \>0.5mg/kg prednisone equivalent daily, whichever is less - Concomitant investigational treatments: receiving other investigational therapies - Known allergy or hypersensitivity reaction to IL-2 injections ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Pregnancy tests must be obtained for female patients. Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method while on study treatment and for six months following completion. Effective contraceptive methods include oral contraceptive pills, patches, or injections, intrauterine devices, having a tubal ligation, having a partner who has had a vasectomy, or not having sex.

Treatments Being Tested

DRUG

CIML-NK Cells

The investigational cell product is a cytokine-induced memory-like natural killer cell preparation, derived from the recipient's haploidentical donor's apheresis product. At the time of infusion, the product is comprised of: * Cytokine-Induced Memory-Like NK cells (CIML-NK cells) * Human Serum Albumin * Plasmalyte The concentration and total cell number of CIML-NK cells in the product will vary based on the recipient body weight and the dose requested.

Frequently Asked Questions

What is the NCT05580601 clinical trial studying?

The objective of this study is to demonstrate that cytokine-induced memory-like natural killer cells can be generated from donor cells and infused safely into patients with relapsed or refractory acute myeloid leukemia (AML). A secondary objective is to assess efficacy of the CIML-NK cells in treating AML. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT05580601?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT05580601?

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
