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
  • Fill out questionnaires
  • Have Cardiopulmonary Exercise Testing (CPET) done
  • Have complete body composition testing done
  • Have muscle and fat composition testing done using a hand-held ultrasound device
