Mycobiome Supporting Diet to Reduce GI Toxicity Associated With ASCT

Study Purpose

The purpose of this study is to determine if this specific Mycobiome Supporting Diet (MSD diet) can help reduce gut inflammation during post-transplant period. The MSD is an special diet which will be explained in detail by a dietician that works by supporting the body's good gut bacteria and fungi.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This is a non-randomized cohort study. Participants will be on a specific diet for 4 weeks prior to transplant and 10 days after transplant, and will then be asked to fill out several questionnaires during this period to see if this diet is easy and simple to follow. The questionnaires will be weekly while participants are outpatient and once admitted to the hospital, participants will need to fill it on the last day (10 days after stem cell infusion). Participants will also be requested to provide fecal swab samples which we will test for bacteria and fungi. A total of 3 samples will be taken at different time points during this study.

Arms & Interventions


Experimental: Mycobiome Supporting Diet

Participants will be able to abide by the allowed and disallowed foods in MSD diet for at least four consecutive weeks prior to conditioning and up to 10 days after transplant. Participants will maintain a diary of foods they consume and any adverse effects they are experiencing and will self- collect fecal samples 28 days before transplant, 2 days before transplant and 10 days after transplant


Behavioral: - Mycobiome Supporting Diet

MSD takes combines elements from several diets (e.g., Paleo, low-carbohydrate, vegetarian, and Mediterranean) and excludes elements of these diets that have been specifically proven to increase pathogenic fungi in the human gut.
