About this study

Official title: Early Clinical Study of Allogenic NK Cells (JD002) in Combination With Chemotherapy in the Treatment of Relapsed or Refractory(r/r) Acute Myeloid Leukemia(AML) After Allo-HSCT

This is an open label, single-arm, Phase I study to evaluate the efficacy and safety of allogenic natural killer(NK) cells in subjects with refractory or relapsed AML after allogeneic hematopoietic stem cell transplantation(allo-HSCT). A leukapheresis procedure will be performed to manufacture NK cells. Prior to allogenic NK cells infusion subjects will receive chemotherapy with azacitidine.

Read the detailed description

This open label, single-arm, Phase I study aims to evaluate the efficacy and safety of allogenic NK cells in subjects with refractory or relapsed AML after allo-HSCT. A leukapheresis procedure will be performed to manufacture NK cells. Prior to allogenic cells infusion subjects will receive chemotherapy with azacitidine. After infusion, the investigators will observe the characteristics of dose limited toxicity (DLT), and determine the maximum tolerable dose(MTD) and recommended phase 2 dose(rp2d) were confirmed. To provide basis for the dosage and treatment plan of cell products in follow-up clinical trials.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing allogenic NK cells in people with Acute Myeloid Leukemia, run by Xuzhou Medical University at 1 site in China.

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 13 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: status not confirmed, as of the sponsor's last update on 27 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Kailin Xu, M.D., Ph.D. (15162166166, lihmd@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-limiting toxicities (time frame: 1 month). 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 27 Feb 2023.
