Microbiota Restoration Therapy for Recurrent Clostridium Difficile Infection (PUNCHCD2)

23 de diciembre de 2020 actualizado por: 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.

Descripción general del estudio

Descripción detallada

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.

Periodo de tiempo
Treatment Success of Group A (2 Doses of RBX2660) vs Group B (2 Doses of Placebo) (ITT)
Periodo de tiempo: 8 weeks after last assigned study treatment
The primary endpoint is to evaluate treatment success, defined as the absence of CDAD without the need for retreatment with C. difficile anti-infective therapy or fecal transplant (FT) at 56 days after administration of the last assigned study enema, of Group A (two enemas of RBX2660) vs. Group B (two enemas of placebo).

Treatment Success was defined as the absence of CDAD without the need for retreatment with C. difficile anti-infective therapy or fecal transplant (FT) at 56 days after administration of the last assigned study enema
8-weeks
Treatment Success Evaluated Between Group A (Two Enemas of RBX2660) Versus Group C (1 Enema of RBX2660 and 1 Enema of Placebo) (ITT)
Periodo de tiempo: 8-weeks
Treatment success, defined as the absence of CDAD without the need for retreatment with C. difficile anti-infective therapy or fecal transplant (FT) at 56 days after administration of the last assigned study enema.
8-weeks
SF-36 Scores Obtained at the 1-week, 4-week, and 8-week Assessments Visits During the Double-blind Period as Compared to Baseline (ITT)
Periodo de tiempo: 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)
Periodo de tiempo: 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.
