LMN-201 for Preventing C. Difficile Infection Recurrence

This study is testing a new treatment called LMN-201 for people who have recently been diagnosed with *Clostridioides difficile* infection (CDI). CDI is a serious gut infection that causes severe diarrhea. LMN-201 is made from a type of spirulina (a blue-green algae) that has been modified to help fight the C. difficile toxins. You would receive either LMN-201 or a placebo (an inactive substance that looks the same) while also getting standard antibiotic treatment for C. difficile. The main goal is to see how many participants achieve a global cure, meaning their infection is gone, up to 16 weeks after starting treatment. This is a multisite study and aims to enroll 375 participants. You can join if you are 18 years or older, have a recent diagnosis of CDI confirmed by a stool test, and have ongoing diarrhea.
