8-K: Tonix Pharmaceuticals Receives FDA Rare Pediatric Disease Designation for TNX-2900 in Prader-Willi Syndrome

Tonix Pharmaceuticals has been granted Rare Pediatric Disease Designation by the FDA for its TNX-2900 product candidate, intended to treat Prader-Willi syndrome in children and adolescents.

Summary

• Tonix Pharmaceuticals announced that the FDA has granted Rare Pediatric Disease Designation to TNX-2900, an intranasal potentiated oxytocin formulation, for the treatment of Prader-Willi syndrome (PWS) in children and adolescents.
• TNX-2900 had previously received Orphan Drug designation in 2022 and its Investigational New Drug application was cleared in 2023.
• The company may be eligible for a transferable Priority Review Voucher upon marketing approval of TNX-2900, which could be sold for approximately $100 million based on recent transactions.
• PWS is the most common genetic cause of life-threatening childhood obesity, and there are currently no approved treatments for hyperphagia, a key symptom of PWS.
• TNX-2900 is designed to enhance the potency of oxytocin and increase its specificity for oxytocin receptors, potentially reducing side effects.
• Tonix is also developing TNX-1900, another intranasal formulation, for other conditions such as adolescent obesity and binge eating disorder.
• The company is prioritizing the submission of a New Drug Application (NDA) for Tonmya in the second half of 2024 for the management of fibromyalgia.
