Researchers are evaluating DMX-200 repagermanium, a drug that blocks a receptor involved in inflammation, in patients with focal segmental glomerulosclerosis FSGS who are also receiving an angiotensin II receptor blocker ARB. This Phase 3 study aims to assess the safety and effectiveness of DMX-200 compared to placebo over two years in adults and adolescents aged 12 to 17 years. The study is led by Dimerix Bioscience Pty Ltd and includes a double-blind period followed by an open-label extension to observe long-term effects. Participants receive either 120 mg of DMX-200 or a matching placebo capsule twice daily for 104 weeks during the double-blind treatment phase. Afterward, those who complete this phase may enter a two-year open-label extension where all participants receive DMX-200 twice daily. The study includes a screening and qualification period lasting 6 to 14 weeks, a possible titration phase, a stabilization phase, and a follow-up period after treatments. Throughout the trial, patients will undergo assessments including urine proteincreatinine ratio and kidney function tests like estimated glomerular filtration rate eGFR at multiple time points up to week 104 and during the extension. Safety and tolerability are closely monitored through regular evaluations, adverse event tracking, and follow-up visits. Total participation may last about 230 weeks, covering all study phases and follow-up periods.

Researchers are evaluating the effectiveness, safety, and tolerability of a vaccine designed to reduce Clostridioides difficile C. difficile infections in adults aged 65 years and older. This phase 3 study compares the vaccine to a placebo in a group of older adults who have recent or planned contact with healthcare systems or recent antibiotic use. The purpose is to understand how well the vaccine works to prevent infections and to monitor any side effects or reactions. Participants will receive either the C. difficile vaccine or a placebo shot injected into the upper arm muscle. The study is randomized, double-blinded, and placebo-controlled. The vaccination period includes two doses and participants will be monitored for up to about three and a half years. Follow-up includes three planned clinical visits and three phone visits initially, then yearly clinic visits until the study ends. Participants are asked to report and save stool samples if they experience three or more loose stools in 24 hours to check for possible infection. During the study, researchers will track local and systemic reactions to the vaccine within seven days after each shot, adverse events up to one month after each vaccination, and serious adverse events for up to 18 months after the last dose. The main measurement is the occurrence of medically attended primary C. difficile infections from two weeks after the second vaccination through the surveillance period. Safety monitoring and annual visits will continue until the study is completed, which could be sooner or later depending on infection rates.
