Introduction: Approximately 1 in 6 patients diagnosed with Clostridioides difficile infection (CDI) experience a recurrence within 2-8 weeks after completing treatment for initial infection. Recurrent CDI (rCDI) leads to persistent use of antibiotics, markedly reduced health-related quality of life (HRQoL), repeated hospitalizations, and death. CDI-SCOPE is a multi-center, single-arm Phase 3b clinical trial exploring the safety and clinical effectiveness of RBX2660, an FDA-approved microbiota suspension, administered by colonoscopy to adults with rCDI.

Methods: All trial participants (target N=40) are invited to take part in a 1-hour interview exploring the burden of rCDI on HRQoL and any positive improvements in HRQoL after treatment. Participants are interviewed 8 weeks after receiving RBX2660 or within 14 days of recurrence – whichever occurs first. A trained interviewer conducts interviews using web-assisted software. Audio recordings are transcribed verbatim and de-identified prior to analysis. A centralized independent review board approved the study.

Results: Data on n=15 interview participants are presented in this interim analysis (participant characteristics in Table 1). All 15 participants (100.0%) completed the 8-week follow-up; none experienced recurrence. Before receiving RBX2660, most reported diarrhea as the most bothersome (66.7%) and the most important symptom (70.0%) to resolve. Participants reported that CDI impacted their day-to-day life (need proximity to bathroom: 80.0%; impacted leisure time: 80.0%; disrupted sleep: 73.3%; ability to eat nutritious meals: 73.3%), affected mental health (fear rCDI would not resolve: 60.0%), and led to debilitating fatigue (60.0%). Post RBX2660 treatment, participants reported diarrhea had either resolved completely (53.3%) or was less severe (46.7%). Average patient-reported diarrhea severity ratings [0-10, no symptoms to worst possible symptoms] dropped from 8.4 (SD: 1.6) before treatment to 0.3 (SD: 0.5) after. Participants described HRQoL improvements (improved physical function: 73.3%: ability to spend time with family again: 73.3%; able to return to leisure activities: 66.7%; feeling better mentally: 66.7%).

Discussion: This interim analysis suggests RBX2660 treatment improves and/or completely resolves diarrhea symptoms and positively impacts key aspects of HRQoL and daily functioning.
