NCT ID NCT06536465
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.

What this could lead to
