Dietary Manipulation of the Microbiome-metabolomic Axis for Mitigating GVHD in Allo HCT Patients
Investigators are evaluating the feasibility, safety and early efficacy of administering a commercially available dietary supplement containing potato-based resistant starch to subjects undergoing allogeneic SCT (stem cell transplant). The intervention will begin immediately prior to the conditioning phase and continue through day 100. Investigators hypothesize that short term administration of a resistant starch is capable of increasing levels of butyrate within the intestine that will reduce rates of acute GVHD (Graft-Versus-Host Disease).
• Subjects undergoing matched related and matched unrelated full intensity allogeneic HSCT.
• Age ≥ 18 years for the feasibility phase. Age ≥10 years old AND ≥50 kg for the phase II portion.
• Karnofsky \>70%, (Karnofsky Performance Status: an attempt to quantify cancer patients' general well-being and activities of daily life. The score ranges from 0 to 100 where 100 is perfect health and 0 is death.)
• Subjects must be able to swallow capsules/tablets
• Ability to understand and the willingness to sign a written informed consent
• Willingness to consent / co-enroll on BMT long term follow up study or HUM00043287 (UMCC2001-0234)
• Availability of an HLA matched related or matched unrelated donor
