Fresh, Frozen or Lyophilized Fecal Microbiota Transplantation for Multiple Recurrent C. Difficile Associated Diarrhea

Phase 1

Completed

Conditions: Recurrent C. Difficile Associated Diarrhea

Interventions: Biological: Fecal Microbiota

Registration Number: NCT02318992

Lead Sponsor: The University of Texas Health Science Center, Houston

Brief Summary: The objective of the study is to investigate the efficacy of fresh, frozen or lyophilized fecal microbiota transplantation (FMT) via colonoscopy in patients with recurrent C. difficile associated diarrhea (RCDAD). Frozen, lyophilized or fresh fecal microbiota transplantation (FMT) inoculum will be generated from well-screened healthy volunteer donors of ≥150 gram/sample. Delivery of FMT will be performed colonoscopically. Fecal samples from donors and recipients will be saved for later metagenomic studies to characterize the microbiome of the gut in patients before and after FMT.

Arm && Interventions

Group	Intervention	Description
Fecal Microbiota_Fresh	Fecal Microbiota	Donor stool (greater than 150 grams) was collected \<4 hours prior to the procedure and then mixed in a homogenizer with 1500 milliliters (mL) (1:10 dilution) sterilized 0.9% sodium chloride (NaCl) in a large sterilized suction canister until a smooth consistency was reached. The suspension was filtered using a coffee filter twice. The microbiota suspension (250mL) was used within 2 hours of preparation (Fresh).
Fecal Microbiota_Lyophilized	Fecal Microbiota	Donor stool (greater than 150 grams) was collected \<4 hours prior to the procedure and then mixed in a homogenizer with 1500 milliliters (mL) (1:10 dilution) sterilized 0.9% NaCl in a large sterilized suction canister until a smooth consistency was reached. The suspension was filtered using a coffee filter twice. The microbiota suspension (250mL) was starting lyophilization process within 30 minutes after completion of stool filtration (Lyophilized). Lyophilized microbiota products were kept at 4 degrees celsius (C) and were used within 6 months after preparation day.
Fecal Microbiota_Frozen	Fecal Microbiota	Donor stool (greater than 150 grams) was collected \<4 hours prior to the procedure and then mixed in a homogenizer with 1500 milliliters (mL) (1:10 dilution) sterilized 0.9% NaCl in a large sterilized suction canister until a smooth consistency was reached. The suspension was filtered using a coffee filter twice. The microbiota suspension (250mL) was kept at -80 degrees Celsius (C) freezer labeled with identity (ID) and expiration date which was 6 months after preparation day (Frozen).
