Tagraxofusp and Azacitidine for Maintenance Treatment in Patients With CD123 Positive AML and MDS Following Donor Hematopoietic Cell Transplant
United States43 participantsStarted 2025-01-28
Plain-language summary
This phase Ib trial tests the safety, side effects, best dose and effectiveness of tagraxofusp in combination with azacitidine as maintenance therapy in treating patients with CD123 positive acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) after a donor (allogeneic) hematopoietic cell transplant. An allogeneic hematopoietic cell transplant (HCT) is a type of transplant where the cancer patient receives cells from another person. Maintenance therapy is given after the transplant to prevent the cancer from coming back. Tagraxofusp is a drug that targets cells that have CD123 on their surface in order to kill the cancer cells to help prevent the cancer from coming back. Azacitidine is in a class of medications called demethylation agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells. Giving tagraxofusp in combination with azacitidine may be safe, tolerable and/or effective maintenance therapy in patients with CD123 positive AML and MDS after an allogeneic HCT.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Documented informed consent of the participant and/or legally authorized representative
* Agreement to allow the use of archival tissue from diagnostic tumor biopsies.
* If unavailable, exceptions may be granted with study principal investigator (PI) approval
* Age: 18-75 years old
* Eastern Cooperative Oncology Group (ECOG) ≤ 2
* First or second allogeneic HCT-eligible patients with AML or MDS with high-risk cytogenetics per European LeukemiaNet (ELN) (AML) or Revised International Prognostic Scoring System (R-IPSS) (MDS); or by having active (morphological) or minimal residual disease (MRD)+ status at the time of HCT (by multicolor flowcytometry, cytogenetics or molecular testing) OR patients who underwent HCT for AML or MDS with high-risk cytogenetics per ELN (AML) or R-IPSS (MDS)
* Positive for CD123 by flow cytometry of either peripheral blood or bone marrow aspirates at the time of diagnosis at any time-point prior to HCT. (Note: CD123 measurement will be conducted using the 10-color Beckman Coulter Navios XL flow cytometer. We will use CD123 PE \[Beckman Coulter #A32535\] to gate the abnormal population of interest. This population will be compared to the internal negative control population \[e.g., T-cells\]. If more than 20% of the abnormal population is positive relative to this control, it will be classified as positive.)
* Any conditioning regiment or GVHD prophylaxis is allowed
* Any donor (i.e., match related/unrelated, mismatched, hapl…
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
