Official title
A Randomized Open Label Pilot Study of Clostridium Butyricum MIYAIRI 588 (CBM588) in Recipients of Allogeneic Hematopoietic Stem Cell Transplantation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This pilot trial studies the side effects and how well CBM588 works in improving clinical outcomes in patients who have undergone donor hematopoietic stem cell transplant. Gut microbiota (formerly called gut flora) is the name given to the microbe (bacteria) population living in the intestine. Gut bacteria help the body to digest certain foods that the stomach and small intestine have not been able to digest. CBM588, may increase gut bacteria biodiversity, prevent recurrent symptoms of gastrointestinal toxicity (ranging from diarrhea to life-threatening inflammation of the colon).
