Market Overview

Global Phenylketonuria Treatment Market was valued at USD 502.18 million in 2024 and is anticipated to witness an impressive growth in the forecast period with a CAGR of 8.25% through 2030. Phenylketonuria (PKU) is a rare genetic disorder that affects an individual's ability to metabolize phenylalanine, an essential amino acid found in protein-containing foods. PKU is an autosomal recessive disorder, meaning it occurs when a person inherits two mutated copies of the PAH gene (phenylalanine hydroxylase gene), one from each parent.The PAH gene provides instructions for making an enzyme called phenylalanine hydroxylase, which is responsible for breaking down phenylalanine in the body. In people with PKU, there is a deficiency or complete absence of phenylalanine hydroxylase enzyme activity due to mutations in the PAH gene. As a result, phenylalanine cannot be effectively converted into tyrosine. The inability to metabolize phenylalanine leads to its accumulation in the bloodstream, resulting in elevated blood phenylalanine levels. High levels of phenylalanine are toxic to the central nervous system. Excess phenylalanine can damage the developing brain, particularly in infants and young children. It can lead to intellectual and developmental disabilities, behavioral problems, seizures, and other neurological complications if left untreated. According to the European Medicines Agency (EMA), Palynziq is a phenylketonuria (PKU) treatment that helps break down phenylalanine using a PEGylated bacterial enzyme, pegvaliase. It is more effective than a placebo in managing blood phenylalanine levels in patients with poorly controlled PKU. Long-term use maintains stable levels for most patients over 18 months.

Key Market Drivers

Increasing Gene Therapy Research

Gene therapy research has the potential to significantly impact the treatment landscape for Phenylketonuria (PKU) and drive the demand for new and innovative PKU treatments. PKU is a genetic disorder caused by mutations in the PAH gene, which results in the inability to properly metabolize phenylalanine, an amino acid found in protein-containing foods. For instance, in March 2024, Eton Pharmaceuticals acquired the U.S. rights to PKU GOLIKE from Relief Therapeutics, expanding its metabolic product portfolio for phenylketonuria (PKU).
