What are the key players in the Primary hyperoxaluria treatment market?

Overview of Primary Hyperoxaluria Primary hyperoxaluria (PH)) is a rare, autosomal recessive genetic disorder that disrupts glyoxylate metabolism in the liver, leading to the overproduction of oxalate. In healthy individuals, oxalate is produced as a by-product of normal metabolism and is eliminated by the kidneys. However, in patients with PH, genetic mutations in key enzymes—such as alanine–glyoxylate aminotransferase (AGT) in PH type 1, glyoxylate reductase/hydroxypyruvate reductase (GR/HPR) in PH type 2, and 4-hydroxy-2-oxoglutarate aldolase in PH type 3—result in a dramatic increase in oxalate production. This excess oxalate combines with calcium to form calcium oxalate crystals that deposit in the urinary tract and kidneys, leading to recurrent kidney stones, nephrocalcinosis, and eventually end-stage renal disease if not adequately managed.

Definition and Causes
PH is defined by its metabolic origin; it stems from inherited mutations that impair the enzymes responsible for converting glyoxylate to less harmful compounds. The most severe form, PH type 1 (PH1), is attributable to mutations in the AGXT gene that encodes the peroxisomal enzyme AGT. The resultant loss of enzymatic function leads to a buildup of glyoxylate, which is then converted to oxalate. This aberrant metabolic pathway directly correlates with the diverse clinical manifestations of the disorder—from mild kidney stone formation in some patients to systemic oxalosis when oxalate accumulation becomes widespread.

Current Treatment Landscape
The conventional treatment paradigm for PH has historically focused on supportive management, comprising hyperhydration, administration of citrate to inhibit calcium oxalate crystallization, and, in some PH1 patients, vitamin B6 (pyridoxine) therapy for those with specific responsive mutations. In advanced cases, combined liver-kidney transplantation has been performed to provide the patient with a source of correct enzyme activity while addressing renal failure. However, these options are often invasive or only partially effective, underscoring the need for innovative therapies that target the underlying metabolic defect. Recently, RNA interference technologies have emerged as a breakthrough, most notably with the approval of lumasiran (marketed as Oxlumo) by Alnylam Pharmaceuticals, which targets glycolate oxidase to reduce oxalate production. In parallel, several novel therapeutic modalities—including substrate reduction, gene therapy, enzyme replacement, and microbial-based approaches—are being developed to offer less invasive and more effective solutions.
