Phase 3 Study of DMX-200 With ARB Treatment for Patients Aged 12 to 80 With Focal Segmental Glomerulosclerosis FSGS

What this Trial Is About

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.
