Could potato starch and an iron drug make stem cell transplants safer?
NCT ID NCT06784336
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This study is for adults with blood disorders who are getting a stem cell transplant from a matched donor. Researchers want to see if giving a special potato starch along with a drug that lowers iron (deferasirox) can help prevent serious complications like graft-versus-host disease (GVHD) and relapse. About 50 participants will take the combo, and the study will track how many stay free of severe GVHD and relapse over time.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients with hematologic disorders undergoing allo-HCT from fully HLA-matched unrelated or related donors after full-intensity conditioning regimen * Age ≥18 years * Karnofsky performance status \>70%, see Appendix A * Patients must be able to swallow capsules/tablets * Ability to understand and the willingness to sign a written informed consent * Availability of a full-HLA matched related or unrelated donor who is medically eligible to donate cells according to the National Marrow Donor Program criteria Exclusion Criteria: * Patients with active inflammatory bowel disease requiring treatment per treating investigator * Patients with a history of gastric bypass surgery * Patients with active Clostridium difficile infection at the time of study enrollment. Active infection is defined as a stool sample positive for Clostridium difficile toxin via enzyme immunoassay (EIA) and either symptoms (frequent loose stools) OR imaging findings consistent with toxic megacolon * Patients with active iron deficiency anemia requiring treatment * Patients with iron overload receiving active treatment with deferasirox * Known hypersensitivity to deferasirox or any component of Jadenu or Exjade * Patients actively enrolled on treatment or in follow up phase on any other GVHD prevention trial * Any physical or psychological condition that, in the opinion of the investigator, would pose an unacceptable risk to the patient or raise concern that the patient would not comply with protocol procedures
