Microbiota Restoration Therapy for Recurrent Clostridium Difficile Infection (PUNCHCD2)
2020년 12월 23일 업데이트: 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.
연구 개요
상세 설명
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.

Treatment Success of Group A (2 Doses of RBX2660) vs Group B (2 Doses of Placebo) (ITT)
기간: 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).

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.
