Evaluation of CRS3123 vs. Oral Vancomycin in Adult Patients With Clostridioides Difficile Infection

Phase 2
Active, not recruiting
Conditions
Clostridioides Difficile Infection
Interventions
Drug: Active Comparator
Registration Number
NCT04781387
Lead Sponsor
Crestone, Inc
Brief Summary

The purpose of this research is to evaluate the primary objectives of safety and efficacy (rate of clinical cure) of 2 dosages of CRS3123 (200 mg and 400 mg) administered orally (po) twice daily (bid) and vancomycin administered 125 mg PO 4 times daily (qid) in adults \> or equal to 18 years of age with a primary episode or first recurrence of CDI. The study will investigate the plasma concentrations and HRQoL outcomes of CRS3123 and additional efficacy endpoints as secondary objectives.

Vancomycin 125 milligramActive ComparatorVancomycin 125 milligram dose (500 mg/day) given orally at approximately 6-hour intervals for 10 days.
CRS3123 400 milligramCRS3123CRS3123 400 milligram dose (800 mg/day) given orally at approximately 6-hour intervals for 10 days. Due to the difference in dosing schedules between CRS3123 (twice a day) and the standard of care vancomycin (four times a day) and appearance of study drugs used in the 3 Arms, placebo will be used to match the total number of capsules in each arm.

Primary Outcome Measures
NameTimeMethod
Rate of Clinical Cure at Test of Cure (TOC) in the Intention to treat (ITT) populationLast dose plus two days
Secondary Outcome Measures
NameTimeMethod
Rate of global cure in the Micro-Intent to Treat, Per Protocol and Microbiologically evaluable populationsTOC - Day 40
Rate of Clinical cure at Test of Cure (TOC) in the Micro-Intent to Treat, Per Protocol and Microbiologically Evaluable populationsLast dose plus two days
Rate of late recurrence of Clostridioides difficile infection (between Day 40 and Day 70) in the Micro-Intent to Treat and Microbiologically Evaluable populationsDay 40 - Day 70
Rate of clinical cure at TOC as assessed by the investigator in the ITT, Micro-ITT, PP, and ME populationsLast dose plus two days
Rate of total relief of symptoms of Clostridioides difficile infection at Test of Cure (TOC) in the Micro-Intent to Treat, Per Protocol and Microbiologically Evaluable populationsLast dose plus two days
Time to resolution of diarrhea through Test of Cure (TOC) in the Micro-Intent to Treat, Per Protocol and Microbiologically Evaluable populationsRandomization until the date of documented resolution, assessed up to 2 days after the last dose of study treatment (TOC)
Rate of early recurrence of Clostridioides difficile infection through Day 40 in the Micro-ITT and ME populationsTOC - Day 40
Rate of recurrence of Clostridioides difficile infection through Day 70 in the Micro-Intent to Treat and Microbiologic Evaluable populationsTOC - Day 70
Clostridium difficile Infection-Daily Symptoms (CDI DaySyms) change from baseline to each post-baseline visit in domain scores (diarrhea symptoms, abdominal symptoms, and systemic/other symptoms) in the Micro-ITT and ME populationsScreening through TOC visit and at suspected recurrence
Time to recurrence of Clostridioides difficile infection through Day 70 in the Micro-Intent to Treat, Per Protocol and Microbiologically Evaluable populationsfrom TOC until the date of recurrence, assessed up to Day 70
