What this trial studies

This trial investigates the effects of high dose vitamin A in preventing gastrointestinal graft versus host disease (GVHD) in adults undergoing donor stem cell transplants. It aims to determine the biologically effective and tolerable dose of vitamin A supplementation prior to transplantation. Participants are divided into treatment and control cohorts, with the treatment group receiving vitamin A and the control group receiving standard care. Additionally, the study evaluates the feasibility of profiling the gut microbiome in relation to vitamin A levels.

Who should consider this trial

Good fit: Ideal candidates are adult patients scheduled for an allogeneic stem cell transplant with a suitable donor match.

Not a fit: Patients with a history of vitamin A hypersensitivity or those with abnormal liver function tests may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of gastrointestinal GVHD in stem cell transplant recipients.

How similar studies have performed: While the use of vitamin A in this context is novel, previous studies have indicated that vitamin A deficiency is linked to increased GVHD risk, suggesting potential for success.
