Plain-language summary
This phase I trial tests the safety, side effects and best dose of NEXI-001 when given with decitabine and lymphodepleting chemotherapy in treating patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory) following an allogeneic hematopoietic cell transplantation from a matched donor. NEXI-001 is a type of chimeric antigen receptor T cell therapy in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Lymphodepleting chemotherapy, with fludarabine and cyclophosphamide, helps kill cancer cells in the body and helps prepare the body for the new CAR-T cells. Giving NEXI-001 with decitabine and lymphodepleting chemotherapy may be safe and tolerable in treating patients with relapsed or refractory AML or MDS following an allogeneic hematopoietic cell transplantation from a matched donor.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* PARTICIPANT: Documented informed consent of the participant and/or legally authorized representative and documented informed consent of the donor
* PARTICIPANT: Agreement to allow the use of archival tissue from diagnostic tumor biopsies (if unavailable, exceptions may be granted with study principal investigator \[PI\] approval)
* PARTICIPANT: Age: ≥ 18 years
* PARTICIPANT: Eastern Cooperative Oncology Group (ECOG) ≤ 1 or Karnofsky performance score (KPS) ≥ 70
* PARTICIPANT: Confirmed diagnosis of AML/MDS that has relapsed after or is refractory to an allogeneic hematopoietic cell transplantation (HCT) from a matched donor.
* Refractory - failure to achieve a complete response minimal residual disease (CRMRD) (-) by multicolor flow cytometry (MFC) or reverse transcription polymerase chain reaction (RT qPCR)
* Relapse - detection of clonal abnormal myeloid blasts by morphology (morphologic relapse) or by MFC, or RT-qPCR analysis (MRD\[+\] relapse) after achieving a CRMRD(-) induced by an allogeneic HCT or maintained by allogeneic HCT administered as consolidation therapy.
Note: Patients who meet the protocol definition of relapse/refractory (r/r) AML/MDS at screening and subsequently achieve a CRMRD(-) response status following protocol-specified bridging therapy will remain eligible to continue participation in this study
* PARTICIPANT: At least 100 days post allogeneic HCT
* PARTICIPANT: Donor match at 8 out of 8 loci for human leucocyte antige…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
