Forecasting Relapse Outcomes With AlloHeme-based Risk Detection in Post-Allo-HCT AML/MDS Patients (FORWARD)
United States400 participantsStarted 2026-08-31
Plain-language summary
AlloHeme is a blood-based monitoring test developed by the CareDx laboratory that utilizes NGS technology coupled with a proprietary algorithm to predict the likelihood of a relapse in post-allo-HCT AML/MDS patients. The technology analyzes 405 single nucleotide polymorphisms (SNPs) selected from across all somatic chromosomes between the donor and the recipient. Pre-transplant DNA is obtained from donor and/or recipient to identify specific donor and recipient SNPs (baseline samples). Post-transplant blood samples are obtained and compared to the baseline sample profiles to precisely calculate the percentage chimerism of recipient cells in the blood samples using a proprietary quantitative method and unique dual indexing that optimizes recipient DNA at trace levels. This approach enables highly accurate and reproducible chimerism measurement with a limit of detection down to 0.02%. The AlloHeme test leverages a proprietary algorithm that integrates this multi-analyte longitudinal chimerism data with post-transplant time points to predict the likelihood of a clinical relapse for AML/MDS patients following an allo-HCT.

Inclusion criteria
. Adults aged 18 years or above.
. The participant must have one of the following diseases: AML or MDS (including CMML) and be eligible for allogeneic hematopoietic stem cell transplant. For participants with active disease (\> 5% blasts) before HCT, the treating physician must have the intent to perform a bone marrow examination at day 30 post-HCT as SOC patient management to confirm complete remission (\<5% blasts).
. Participant must receive an allo-HCT from an HLA-matched related or unrelated donor, an HLA-mismatched donor, or a haploidentical donor.
. Participant can be enrolled before, at, or up to 1-month post-allo-HCT as long as the participant is in complete remission (CR) at Day 30 and that a recipient pre-transplant or donor sample is available for baseline genotyping (reference). If the reference sample is unavailable or fails testing, the buccal swab collected at Day 30 may be used as the reference sample.
. Myeloablative or reduced intensity/non-myeloablative conditioning except T-cell depleting therapies (Ex-vivo T cell depletion, CD34 selected graft, use of anti-thymocyte globulin or alemtuzumab).
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.
What they're measuring
1
To evaluate AlloHeme test performance in predicting post-transplant relapse (by FDA criteria) or any cytogenetic/molecular evidence of disease resulting in unplanned treatment intervention in AML and MDS patients.
. Any graft versus host disease (GVHD) prophylaxis regimen.
. Willing and able to provide written informed consent.
. Willing and able to comply with study visits and procedures, including scheduled sample collections and clinical assessments
Exclusion criteria
. History of prior allo-HCT or any prior solid organ transplant.
. Syngeneic donor (identical twin).
. T cell depleted transplant (Ex-vivo T cell depletion, CD34 selected graft, use of antithymocyte globulin or alemtuzumab in the conditioning regimen)
. Cord blood graft.
. Pregnancy
. Any condition that, in the investigator's opinion, would interfere with the participant's ability to comply with study procedures or jeopardize their safety.
. Concurrent participation in an interventional or maintenance clinical trial for post allo-HCT relapse prevention; co-enrollment with other trials, such as those intended for GVHD / infection prevention or improving supportive care, is allowed.
