Key Takeaways from the Phenylketonuria Pipeline Report
- On April 24, 2026- Otsuka Pharmaceutical Development & Commercialization Inc. announced a Phase 2 study is to assess the safety, tolerability, and pharmacokinetics (PK) of oral JNT-517 in adolescents (12 to less than 18 years of age) with PKU. Participants will receive either JNT-517 or placebo and will be blinded to their treatment assignment. Participants will have a 4 in 5 (or 80%) chance of receiving JNT-517. The study will last for up to 63 days including a Screening period, Treatment period and Follow-up period for safety.
- On April 24, 2026- PTC Therapeutics initiated a phase 3 study is to evaluate the long-term safety of PTC923 in participants with phenylketonuria, and to evaluate the changes from baseline in dietary phenylalanine (Phe)/protein consumption.

Phenylketonuria Overview
Phenylketonuria (PKU) is a rare inherited metabolic disorder caused primarily by mutations in the PAH gene, which lead to a deficiency or complete absence of the enzyme phenylalanine hydroxylase (PAH). This enzyme is essential for converting the amino acid phenylalanine into tyrosine, and without it, phenylalanine accumulates to toxic levels in the body, particularly affecting the brain. PKU is inherited in an autosomal recessive manner, meaning a child must inherit the defective gene from both parents to be affected. In rare cases, mutations affecting the cofactor tetrahydrobiopterin (BH4) or the DNAJC12 gene can also disrupt phenylalanine metabolism, resulting in related disorders. Newborns with PKU typically appear healthy at birth but, if left untreated, will begin to show signs such as intellectual disability, developmental delay, seizures, and behavioral issues within the first few months. Additional symptoms include hypopigmentation, a musty body odor, eczema, and in some cases, movement disorders. Adults with poorly managed PKU may suffer from cognitive decline, mood disorders, and challenges in social functioning. Early diagnosis through newborn screening and strict dietary management can prevent most severe complications, though symptom severity varies depending on the level of enzyme deficiency.
Phenylketonuria Emerging Drugs Profile
- JNT-517: Otsuka Pharmaceutical
JNT-517 is an oral, selective small molecule inhibitor targeting the Phe transporter SLC6A19, offering a novel therapeutic approach for the treatment of phenylketonuria (PKU). It acts at a unique, cryptic allosteric site to block the kidney reabsorption of phenylalanine (Phe), helping to lower elevated blood Phe levels. By targeting a key mechanism of Phe transport, JNT-517 has the potential to benefit individuals with PKU regardless of age or genetic profile. Its oral formulation makes it a convenient option for long-term management. Currently, the drug is in Phase III stage of its clinical trial for treatment of Phenylketonuria (PKU).
- RLF OD032: Relief Therapeutics Holding
RLF-OD032 is an innovative, highly concentrated liquid formulation of sapropterin dihydrochloride developed for oral use. It is intended for the treatment of phenylketonuria (PKU) in both adult and pediatric patients. The product is being submitted for US regulatory approval through the 505(b) (2) NDA pathway, supported by bioequivalence to a reference listed drug. If approved, RLF-OD032 would be the first and only ready-to-use, portable liquid sapropterin therapy. This unique formulation aims to improve PKU management by enhancing treatment adherence and patient quality of life. Currently, the drug is in Phase II stage of its clinical trial for treatment of Phenylketonuria (PKU).
- NGGT 002: Next Generation Gene Therapeutics
NGGT002 is an investigational gene therapy being developed by Next Generation Gene Therapeutics for the treatment of Phenylketonuria (PKU). NGGT002 has already demonstrated promising results in a completed proof-of-concept Investigator-Initiated Trial (IIT) in humans. The therapy is designed to address the underlying genetic cause of PKU by restoring normal metabolic function. Currently, the drug is being evaluated in Phase I/II stage of its clinical trial for treatment of Phenylketonuria (PKU).
