Key Takeaways from the Phenylketonuria Pipeline Report

• In March 2025, Sanofi announced a study is constituted of 2 separate parts: a dose escalation part, and a dose expansion part where subsequent participants will be administered a safe and effective dose level identified during the dose escalation part. In both study parts, clinical and laboratory assessments will be collected to: a) assess the incidence of adverse events, and b) evaluate the effect of SAR444836 on reductions in blood Phe levels and maintenance of these Phe levels after elimination of a Phe restricted diet.
• In March 2025, PTC Therapeutics conducted a study includes 2 parts: Part 1 and 2. Part 1 is an open-label sepiapterin-responsiveness test, and Part 2 is an open-label treatment period.

Phenylketonuria Emerging Drugs

• Sepiapterin: PTC Therapeutics

Sepiapterin (formerly PTC923), an oral formulation of synthetic sepiapterin, has a dual mechanism of action to increase activity of the phenylalanine hydroxylase (PAH) enzyme. First, sepiapterin is a precursor compound that is rapidly absorbed and converted intracellularly to tetrahydrobiopterin (BH4), a critical cofactor of PAH. Sepiapterin also has an independent chaperone effect, protecting against PAH misfolding to enhance the enzyme function. Through this dual mechanism of action, sepiapterin effectively reduces blood phenylalanine (Phe) levels and has the potential to treat the broad range of PKU patients. Currently the drug is in been registered for Phenylketonuria (PKU).

• JNT-517: Otsuka Pharmaceutical

JNT-517 is a selective small molecule inhibitor of the Phe transporter SLC6A19 that has the potential to be a first-in-class oral therapy used to treat any person with PKU, regardless of age or genotype. JNT-517 acts at a novel, cryptic allosteric site to block kidney reabsorption of Phe and offers a promising new approach to reduce blood. . Currently the drug is in Phase III for Phenylketonuria (PKU).

• RLF OD032: Relief Therapeutics Holding

RLF-OD032, an innovative and highly concentrated liquid formulation of sapropterin dihydrochloride, is designed to lower blood phenylalanine in adult and pediatric PKU patients. It offers a more patient-friendly solution by significantly reducing the volume of medication required compared to current formulations. This advancement aims to enhance compliance, particularly among pediatric patients, who often struggle with the high volumes associated with existing sapropterin treatments. If approved, RLF-OD032 would be the first and only portable, ready-to-use liquid formulation of sapropterin dihydrochloride. Currently the drug is in Phase I Stage of its development for the treatment of Phenylketonuria (PKU).
