Phase 2a Study to Evaluate the Effectiveness and Safety of BAY 3401016 in Adults Aged 18 to 45 With Alport Syndrome

What this Trial Is About

Alport syndrome AS is a rare genetic disorder caused by changes in specific genes that produce collagen, leading to kidney disease, hearing loss, and eye problems. People with AS face a high risk of chronic kidney disease CKD, which gradually reduces kidney function and can lead to end-stage kidney disease. A common sign of worsening kidney function is proteinuria, the presence of excess protein in the urine. This study evaluates the effects of BAY 3401016, a monoclonal antibody designed to block the protein Semaphorin 3A Sema3A, which may contribute to kidney damage in AS. Participants are randomly assigned to receive either BAY 3401016 or a placebo once weekly for 24 weeks, alongside their background therapy. The study includes an extension phase to further assess the treatments safety and efficacy. Participants will be involved for at least 24 weeks of treatment, followed by a 90-day follow-up period. Researchers will monitor kidney function by measuring the urinary albumin creatinine ratio UACR at several points during treatment and after its completion. Safety and tolerability of BAY 3401016 will also be carefully assessed throughout the study period.
