BOSTON, August 11, 2023 – Jnana Therapeutics, a clinical-stage biotechnology company leveraging its next-generation chemoproteomics platform to discover medicines for challenging-to-drug targets, today announced that the Company will present the chemical structure of JNT-517, a clinical candidate for the treatment of phenylketonuria (PKU), as well as new data on its discovery and characterization at the American Chemical Society (ACS) Fall 2023 national meeting. The meeting will be held in San Francisco from August 13-17, 2023.

Jnana is advancing JNT-517, an allosteric small molecule inhibitor of the phenylalanine (Phe) transporter SLC6A19, in Phase 1b clinical development as a potential first-in-class oral treatment for PKU. 

The Company’s oral presentation in the First Time Disclosures session at ACS Fall 2023 will discuss:

  • The discovery effort using Jnana’s RAPID chemoproteomics platform, which led to small molecules that inhibited SLC6A19 through a cryptic allosteric site
  • Demonstration of in vivo activity in the Pahenu2 mouse model of classical PKU
  • How this work led to the identification of JNT-517, as well as the chemical structure of the clinical candidate

About JNT-517

JNT-517 is a selective small molecule inhibitor of the phenylalanine 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 Phe levels. The U.S. Food and Drug Administration granted JNT-517 Rare Pediatric Disease Designation in late 2022.
