Registration Number
NCT05515562
Lead Sponsor
Wake Forest University Health Sciences
Brief Summary

Given the clinical need to improve upon current antibiotic regimens for the treatment of C. difficile infection with a particular focus on the impact of therapies on gut microbiome, this study proposes to characterize the impact of Intravenous (IV) omadacycline on gut microbiome of healthy volunteers.

Detailed Description

The plan to enroll eight healthy volunteers between the ages of 18 and 40 years and without history of cardiovascular, gastrointestinal, hepatic, or renal disease to receive 5 days of intravenous omadacycline followed by 5 days of oral omadacycline. Stool and saliva samples will be collected at pre-specified times and analyzed to characterize the impact of IV omadacycline on gut microbiome.
