KUVAN (sapropterin dihydrochloride) is an oral powder cofactor replacement therapy for phenylketonuria (PKU) that works by activating residual phenylalanine hydroxylase (PAH) enzyme activity to reduce phenylalanine levels. It restores BH4, the natural cofactor required for PAH to convert phenylalanine to tyrosine through normal oxidative metabolism. KUVAN is used in PKU patients who retain some PAH enzyme function and can respond to cofactor augmentation.
Product is at peak lifecycle with stable modest Part D utilization (~426 claims annually), suggesting a mature, niche orphan indication with limited commercial growth potential.
