SEED receives FDA Rare Pediatric Disease, Orphan Drug designations for ST-01156

SEED Therapeutics announced that the U.S. Food and Drug Administration has granted Rare Pediatric Disease and Orphan Drug designations to SEED’s ST-01156 molecular glue. This novel agent degrades RBM39, an RNA splicing factor implicated in multiple mechanism-targeted solid tumor indications. SEED is advancing ST-01156 toward an Investigational New Drug application, with an expected IND filing in the first half of 2025. The Rare Pediatric Disease designation positions SEED to potentially receive an FDA priority review voucher upon approval of ST-01156. SEED also announced that its largest shareholder, BeyondSpring (BYSI), has entered into definitive agreements to sell a portion of its Series A-1 Preferred Shares of SEED. Upon completion of the transactions, BeyondSpring is expected to retain approximately 14.4% of SEED’s outstanding shares.
