Lumasiran

Published: July 26, 2026Updated: July 26, 2026

Lumasiran is an RNA interference (RNAi) therapeutic agent designed to treat primary hyperoxaluria type 1 (PH1), a rare genetic disorder characterized by excessive oxalate production. By reducing the glycolate oxidase enzyme in liver cells, lumasiran decreases oxalate synthesis, thereby preventing the formation of kidney stones and renal damage associated with this condition.

Quick summary

Lumasiran is an RNAi therapy that reduces oxalate production in the liver for patients with primary hyperoxaluria type 1.

Value:Targets glycolate oxidase (GO) to reduce oxalate production

Primary pharmacological mechanism

Lumasiran is indicated for the treatment of primary hyperoxaluria type 1 (PH1) in both adults and pediatric patients. PH1 is a rare autosomal recessive disorder caused by deficiency of the enzyme alanine-glyoxylate aminotransferase (AGT), leading to overproduction of oxalate, which can cause recurrent kidney stones, nephrocalcinosis, and systemic oxalosis.

Lumasiran utilizes small interfering RNA (siRNA) technology to target and degrade hydroxyacid oxidase 1 (HAO1) messenger RNA in hepatocytes. This reduces production of the glycolate oxidase enzyme, which in turn decreases the conversion of glycolate to glyoxylate. With less glyoxylate available as a substrate, oxalate synthesis is significantly reduced, lowering urinary and plasma oxalate levels.

Lumasiran is administered by subcutaneous injection, typically with loading doses followed by maintenance doses every three months. Common adverse reactions include injection site reactions and abdominal pain. Patients should be monitored for reductions in plasma oxalate levels and may require concurrent pyridoxine (vitamin B6) supplementation in some cases. This medication should be used under the supervision of physicians experienced in managing metabolic disorders.
