Series C financing led by Bain Capital Life Sciences to support PKU program and pipeline in immune-mediated diseases and cancer; Ron Renaud joins Jnana's Board of Directors
Jnana initiates Phase 1 clinical trial of JNT-517, a potential first-in-class oral treatment for PKU; JNT-517 receives US FDA Rare Pediatric Disease Designation
BOSTON, Nov. 15, 2022 /PRNewswire/ -- Jnana Therapeutics ("Jnana"), a biotechnology company leveraging its next-generation chemoproteomics platform to discover medicines for challenging-to-drug targets, today announced the close of its $107 million Series C financing. The financing was led by Bain Capital Life Sciences with participation from existing investors including RA Capital Management, Polaris Partners, Versant Ventures, Avalon Ventures and Pfizer Ventures.
The proceeds from the funding will be used to progress the company's lead program in phenylketonuria (PKU), a rare genetic metabolic disease, through a clinical proof-of-concept (POC) study, and to advance additional wholly owned, potential first-in-class medicines in immune-mediated diseases and cancer. Jnana's RAPID chemoproteomics platform enabled the identification of JNT-517, a small-molecule inhibitor of the phenylalanine transporter SLC6A19 that acts at a novel, cryptic allosteric site, as well as a growing pipeline of programs against challenging-to-drug targets such as transcription factors.
"We are thrilled to welcome Bain Capital Life Sciences to our strong syndicate of leading life science investors who share our vision for the potential of our RAPID platform and lead program in PKU," said Joanne Kotz, Ph.D., co-founder and CEO of Jnana Therapeutics. "With their support and the initiation of our second collaboration with Roche, we are well positioned to deliver on our aim of developing breakthrough medicines for patients."
Jnana also announced the dosing of the first healthy volunteers in a Phase 1 study evaluating JNT-517, its clinical candidate for the potential treatment of PKU. After the Phase 1a portion in healthy volunteers, JNT-517 will be evaluated in a Phase 1b study in individuals with PKU, with the potential to demonstrate clinical POC. In addition, the company announced that JNT-517 has been granted Rare Pediatric Disease Designation by the US Food and Drug Administration.
"With its unique mechanism of action of blocking phenylalanine reabsorption in the kidney, JNT-517 has the potential to be the first therapy for all individuals living with PKU, regardless of genetic background or age," said Joel C. Barrish, Ph.D., co-founder, President and CSO of Jnana Therapeutics. "The Rare Pediatric Disease Designation by the FDA underscores the promise of JNT-517 to accelerate innovation for these patients with limited treatment options."
"We share Jnana's patient-focused mission and commitment to developing the next generation of best-in-class therapies that address high unmet medical needs across a wide range of diseases," said Ron Renaud, a Managing Director at Bain Capital Life Sciences who is joining Jnana's Board of Directors in conjunction with the financing. "We are excited to support Jnana as they progress their PKU program into clinical development and advance their innovative pipeline of potential novel medicines against challenging-to-drug targets."
About PKU
Phenylketonuria (PKU) is an inherited metabolic disorder caused by a deficiency of the enzyme phenylalanine hydroxylase (PAH). This enzyme is required for the breakdown of phenylalanine (Phe), an amino acid found in all protein-containing foods. When PAH is deficient or defective, Phe accumulates to abnormally high levels in the blood. If left untreated, these toxic levels of Phe in the blood can result in progressive and severe neurological impairment and neuropsychological complications. The SLC transporter SLC6A19 is responsible for kidney reabsorption of Phe back into the bloodstream, and the inhibition of SLC6A19 offers a novel, oral approach for the treatment of PKU.
