This study looked at whether giving the antibiotic vancomycin helps cancer patients who have diarrhea and a positive screening test for C. difficile but a negative toxin test. Only 9 patients were enrolled, far fewer than planned. Researchers measured changes in C. difficile leve…

This study tested whether eating less fat and more fiber can reduce the chance of a repeat Clostridioides difficile infection in cancer patients. Eight participants with leukemia, lymphoma, or other cancers followed a specific diet. Researchers tracked diarrhea and measured C. di…

This study tested whether taking capsules containing healthy gut bacteria could help clear drug-resistant germs (including C. difficile) from the intestines of 42 hospitalized adults who needed at least 7 days of antibiotics. Participants received either the bacteria capsules or …

This phase 2 study tested an experimental antibiotic called CRS3123 against the standard treatment vancomycin for Clostridioides difficile infection (C. diff). 43 adults with a first episode or first recurrence of C. diff took either CRS3123 or vancomycin for 10 days. The main go…

This study tested fecal microbiota transplant (FMT) in 24 adults with recurrent Clostridium difficile infection (C. diff) that didn't get better with standard antibiotics. FMT involves placing healthy donor stool into the patient's colon to restore good bacteria. The goal was to …

This study tested whether adding the drug bezlotoxumab to standard treatment could prevent serious outcomes in people with a severe C. diff infection. Researchers used a special score to identify 44 high-risk patients. The goal was to see if the drug reduced organ failure, infect…

This study tests a new delayed-release metronidazole capsule designed to release the drug directly in the colon, where C. diff bacteria live. 18 healthy adults will receive a single dose of either the new capsule or the standard tablet to compare how much drug reaches the colon v…

This small pilot study tested a drug called 3,4-diaminopyridine (FIRDAPSE) in 3 people with severe botulism who needed a ventilator to breathe. The goal was to see if the drug could improve nerve signals and breathing. Because only 3 people took part, the results are very prelimi…

This study tested an experimental drug called TNM002 in 240 healthy Chinese adults to see if it can protect against tetanus as well as the standard treatment. Participants received a single injection of TNM002 at different doses, the standard tetanus antibody, or a placebo. The m…
