New plant-based ulcerative colitis drug targets FDA IND filing in 2026
Curanex (Nasdaq: CURX) has completed a GMP-compliant pilot-scale batch of its lead botanical drug candidate, Phyto-N, as it prepares for an Investigational New Drug (IND) submission for ulcerative colitis. The company is targeting a Q4 2026 IND submission and is advancing GLP toxicology and pharmacokinetic studies. This milestone follows positive non-GLP safety studies and positions Curanex for future clinical development.
