Lumasiran treatment for patients on dialysis with high oxalate levels

Lumasiran in Hyperoxalaemic Patients on Haemodialysis

Phase 2 Interventional Charite University, Berlin, Germany · NCT06225544

What this trial studies

This clinical trial investigates the effectiveness of lumasiran, a drug designed to reduce oxalate levels in the blood, in patients undergoing haemodialysis due to end-stage kidney disease. The study is a double-blind, phase II trial where participants are randomly assigned to receive either lumasiran or a placebo. The primary goal is to determine if lumasiran can significantly lower pre-dialysis oxalate levels over a period of 3-6 months, while also monitoring cardiovascular health and tolerability. Monthly plasma oxalate measurements and cardiac assessments will be conducted to evaluate the drug's impact.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 who are stable on haemodialysis and have elevated serum oxalate levels.

Not a fit: Patients with end-stage kidney disease caused by primary hyperoxaluria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the health outcomes of dialysis patients by lowering oxalate levels and potentially reducing cardiovascular risks.

How similar studies have performed: Previous studies have shown lumasiran to be well tolerated, indicating potential for success in this patient population.
