Summary

This study tested a new drug called REC-3964 to see if it could prevent repeat Clostridioides difficile (C. diff) infections in adults. Only 3 people were enrolled before the trial was stopped early. The goal was to check safety and whether the drug helped people stay infection-free for 8 weeks.
