Atacicept in Multiple Glomerular Diseases (PIONEER)
About This Study
This Phase 2 study evaluates the safety, tolerability, and efficacy of atacicept in adult and adolescent patients aged 10 and older with autoimmune glomerular diseases. The target population includes patients diagnosed with IgAN, pMN, MCD, or FSGS. Participants receive weekly subcutaneous injections of atacicept to determine its impact on reducing UPCR and preserving renal function. Primary endpoints focus on the drug's safety profile and its ability to achieve clinical remission across these specific nephropathies.
