Microbiota Restoration Therapy for Recurrent Clostridium Difficile Infection (PUNCHCD2)

23. desember 2020 oppdatert av: Rebiotix Inc.

A Phase 2B Prospective, Randomized, Double-blinded, Placebo-controlled Clinical Study Demonstrating the Efficacy and Safety of Rebiotix RBX2660 (Microbiota Suspension) for the Treatment of Recurrent Clostridium Difficile Infection

This is the first prospective, multi-center, double-blinded, randomized controlled study of a microbiota suspension derived from intestinal microbes. Patients who have had at least two recurrences of C. difficile infection (CDI) after a primary episode and have completed at least two rounds of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization may be eligible for the study. Patients whose CDI returns in less than 8 weeks after the last assigned study treatment may be eligible to receive up to 2 treatments with RBX2660 in the open-label portion of the study.

Detaljert beskrivelse

This is the first prospective, multi-center, double-blinded, randomized controlled study of a microbiota suspension derived from intestinal microbes. The primary assessments for this study are (i) efficacy of RBX2660 compared to placebo at 8 weeks and (ii) safety via assessment of adverse events. Study visits are at 1-, 4- and 8-weeks after treatment with additional follow-up at 3, 6 12 and 24 months post treatment. Patients who have had at least two recurrences of C. difficile infection (CDI) after a primary episode and have completed at least two rounds of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization may be eligible for the study. Patients whose CDI returns in less than 8 weeks after the last assigned study treatment may be eligible to receive up to 2 treatments with RBX2660 in the open-label portion of the study.

Tidsramme: 8-week
The validated SF-36 scale was used to identify changes to quality of life (QoL) following study treatment. Each component is analyzed on a norm-based scoring (0-100) with a higher score representing an improvement in QoL.
8-week
Time to CDAD Recurrence After Completion of the Assigned Study Treatment for Group A vs. Group B (ITT)
Tidsramme: 8-weeks
Time to CDI Recurrence was evaluated using Kaplan-Meier Analysis and expressed by percentage of subjects who were recurrence free at a certain time point (every 7 days) from completion of the last blinded enema.
