Spyre Therapeutics hit the key target in a trial of its candidate treatment for moderate to severely active ulcerative colitis.
The clinical-stage biotechnology company said Monday it achieved positive 12-week induction data from the first part of its Phase 2 Skyline trial of SPY001.
The study met its primary endpoint with a statistically significant reduction of 9.2 points from baseline at week 12 in a Robart's Histopathology Index score. Secondary endpoints included clinical remission by modified Mayo score of 40% and endoscopic improvement of 51%, Spyre said.
SPY001 was well tolerated, the company said.
Trading in Spyre's shares was halted ahead of the news.
The company said recruitment for part A of Skyline is now closed and that enrollment is open for part B, which it said includes three monotherapy cohorts and three combination cohorts. Proof-of-concept induction data for the remaining cohorts of part A are now expected mid-2026 for SPY002 and in the third quarter for SPY003, Spyre said. Part B induction data for all cohorts remain on track for 2027, it said.
