Researchers are conducting a two-part, phase 2b/3 study to evaluate CSL300 (Clazakizumab) in adults with end stage kidney disease (ESKD) undergoing dialysis who have systemic inflammation and either atherosclerotic cardiovascular disease (ASCVD) or diabetes. The study aims to determine the best dose of CSL300 and assess its effects on cardiovascular outcomes and safety in this population. This multicenter, randomized, double-blind, placebo-controlled trial targets patients with elevated inflammation markers and significant health risks due to their conditions. In the first part (phase 2b), the study focuses on finding the appropriate dose of CSL300 compared to placebo. CSL300 is given through intravenous (IV) administration. The second part (phase 3) evaluates the impact of CSL300 on cardiovascular events such as heart attack or cardiovascular death over approximately 5 years, continuing to compare CSL300 to placebo for safety and efficacy. The placebo matches CSL300's excipient content but lacks the active drug. Participants will undergo baseline and regular assessments for inflammation markers like high-sensitivity C-reactive protein (hs-CRP) up to 12 weeks in phase 2b, and long-term monitoring for cardiovascular outcomes in phase 3. The study involves ongoing safety evaluations and efficacy measurements during the entire follow-up period. This comprehensive approach helps researchers understand how CSL300 affects inflammation and cardiovascular health in patients with ESKD on dialysis.

Researchers are evaluating VX-147 for its effectiveness, safety, tolerability, and how the body processes it in adults and children aged 10 to 65 who have apolipoprotein L1 (APOL1)-mediated proteinuric kidney disease. This study is a Phase 2/3 trial designed to better understand treatment options for this specific kidney condition. Participants will receive either VX-147 or a placebo, both given as oral tablets. The study is double-blind and placebo-controlled, meaning neither participants nor researchers know who receives the active drug or placebo during the treatment period. The trial consists of two parts: Part A focuses on treatment effects over at least 48 weeks, while Part B involves continued safety and tolerability observation for approximately four years after the last participant enrolls. Throughout the study, participants will undergo regular assessments including measurements of urine protein to creatinine ratio and kidney function via estimated glomerular filtration rate (eGFR). Safety is monitored by tracking adverse events and serious adverse events. Data will be collected during the treatment period and followed long-term to evaluate both efficacy and safety outcomes, with some measures assessed at interim and final analyses over at least two years.

Researchers are evaluating VX-407 in adults aged 18 to 65 who have Autosomal Dominant Polycystic Kidney Disease (ADPKD) with specific PKD1 gene variants. This Phase 2a open-label study focuses on how VX-407 affects height-adjusted total kidney volume (htTKV), along with its safety, tolerability, and how the body processes the drug (pharmacokinetics). Participants will receive VX-407 tablets taken orally during the study. The trial involves monitoring changes in htTKV via MRI scans over a period from baseline up to 52 weeks. The study is designed as a single-arm trial without a comparison group. During the study, participants will undergo scheduled visits including abdominal MRI scans to measure kidney volume and assessments of kidney function through estimated glomerular filtration rate (eGFR). Researchers will track safety and collect pharmacokinetic data to understand drug behavior. The total study duration for each participant is about one year, with ongoing evaluations to monitor treatment effects and safety.
