Epigenetic drugs aim to stop cancer return after transplant in kids
NCT ID NCT03843528
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This trial tests whether adding two drugs—vorinostat and low-dose azacitidine—after a stem cell transplant can help prevent relapse in children with certain myeloid cancers. The study includes children aged 1 to 21 with acute myeloid leukemia or related conditions. Researchers are looking for the safest dose of vorinostat when used with azacitidine, while also tracking side effects, graft-versus-host disease, and survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- vorinostat and low-dose azacitidine
- What this could lead to
- If it works, this combination could help prevent cancer relapse in children after a stem cell transplant, improving survival.
- What could go wrong
- This is an early, small dose-finding study, so safety and effectiveness are not yet known. Side effects from the drugs may limit their use.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patient is 1 year to 21 years of age. 2. Patient has a diagnosis of AML, MDS, MDS/AML, MPAL, or JMML. Note: patients are allowed to have received a HMA or HDACi prior to undergoing alloHCT. 3. Patient has undergone allogeneic hematopoietic cell transplantation (no restrictions on conditioning regimen, donor or stem cell source, or GVHD prophylaxis regimen). 4. Patient and/or parent(s) or legal guardian(s) are capable of understanding the study, including potential benefits and risks, and sign written informed consent. Age-appropriate assent will be obtained. 5. Female patient of childbearing potential has a negative screening pregnancy test (urine or serum, as per local institutional standard). 6. Female patient with infant(s) agrees not to breastfeed her infant(s) while on study. 7. Patient of child-bearing potential (male and female) agrees to use effective method of contraception during the study. Exclusion Criteria: 1. Patient is enrolled on a clinical trial with investigational post-transplant medications. Note: trials involving defibrotide, post-transplant cyclophosphamide, and Lactobacillus plantarum are permitted. Other trials involving investigational medications that aren't leukemia or GVHD-directed may also be permitted after consultation with the overall PI. 2. Patient has a planned administration of non-protocol chemotherapy, radiation therapy, donor leukocyte infusion, or immunotherapy during the planned study period. 3. Patient has a known allergy to azacitidine or vorinostat. 4. Patient has chronic myelogenous leukemia. 5. Concomitant use of coumarin-derived anticoagulants or valproic acid. \-
