A Study of Microbiome Transplantation for the Treatment of Constipation and/or Significant Bloating in Patients With Systemic Sclerosis
The University of Texas Health Science Center, Houston
Summary
The purpose of this study is to characterize the intestinal flora in subjects with systemic sclerosis-related constipation and/or significant bloating and to determine safety and trends in improvements in the diversity of colonic microbiome and patient symptoms following the administration of either frozen or lyophilized PRIM-DJ2727 microbiota.
Description
The purpose of this study is to evaluate the tolerability and safety of frozen and lyophilized microbiome transplant product (PRIM- DJ2727), to characterize the microbiome (α-diversity and β-diversity) and metabolome in patients with Systemic Sclerosis (SSc)-related constipation and/or significant bloating, to examine improvement in constipation and/or significant bloating after microbiome transplant, to examine improved colonic transit after microbiome transplant, to examine subjective global improvement and improvement in SSc disease characteristics, to monitor change in concentration of sys…

Interventions
- DrugPRIM-DJ2727
For oral administration, each dose will contain the number of capsules needed to deliver the lyophilized intestinal bacteria powder derived after lyophilization of 60 g of filtered stool in 300 mL 0.85% NaCl and 2% mannitol. Participants will take the capsules (5-6 capsules twice weekly) from week 2 through week 10. Capsules will be taken over a period of up to one hour to maximize tolerance and ensure the capsules are not expelled by vomiting. For administration via retention enema, which will be done at baseline and week 11, 50 g of filtered, frozen stool in 250 mL of 0.85% sodium chloride (NaCl) will be used.
- DrugPlacebo
Placebo will be administered as capsules from week 2-10 and as enema at baseline and week 11.
