KUVAN (sapropterin dihydrochloride) is an oral powder formulation that acts as a cofactor for phenylalanine hydroxylase (PAH), the deficient enzyme in phenylketonuria (PKU). By restoring PAH activity, KUVAN enables the normal oxidative metabolism of phenylalanine and reduces plasma Phe levels in responsive PKU patients. It represents a mechanistic breakthrough in treating a rare genetic metabolic disorder previously managed only through dietary restriction.
Product is at peak maturity with stable, niche market penetration; team size remains focused on specialty care and patient support rather than high-volume commercial expansion.
BH4, the cofactor for the enzyme phenylalanine hydroxylase (PAH). PAH hydroxylates Phe through an oxidative reaction to form tyrosine. In patients with PKU, PAH activity is absent or deficient. Treatment with BH4 can activate residual PAH enzyme activity, improve the normal oxidative metabolism of…
