Ph I/II of GOS in acute GVHD (Stem Cell Transplantation)

What is the Purpose of this Study?

We are doing this study to see if taking a prebiotic (dietary supplement) can reduce the risk of acute graft-versus-host disease (a common complication) in people who receive an allogeneic stem cell transplant. This study is important because prebiotics are a common and safe dietary supplement, and there is a need for a safe and effective way to reduce graft-versus-host disease after transplant.

What is the Condition Being Studied?

Allogeneic (Donor) Stem Cell Transplant

Who Can Participate in the Study?

Adults ages 18-80 who:
- Are scheduled to get an allogeneic stem cell transplant for any type of illness
- Are able to read and write in English
- Are not pregnant or nursing
- Do not have any disease or condition affecting their digestive tract
- Are not using any prebiotic, probiotic, or antibiotic

What is Involved?

If you choose to join the study, you will:
-Be randomly asssigned (like a coin flip) to receive the prebiotic (food additive that affects gut bacteria) or a placebo (food additive that does not affect gut bacteria)
- Give stool samples
- Have your skin swabbed
- Have blood draws
