Rigel Pharmaceuticals: A Four-Drug Company With A Clinical Catalyst Ahead

Rigel Pharmaceuticals in-licensed Veppanu, a drug for the treatment of certain breast cancer patients, targeting a $1B market, with revenues expected as early as Q3'26. Q2'26 saw strong sales growth from Tavalisse and Rezlidhia, offsetting Gavreto's middling performance. RIGL guides $285M–$295M 2026 revenues, excluding Veppanu upside. Upcoming R289 phase 1b data for LR-MDS and future readouts from Veppanu and Rezlidhia trials provide additional growth catalysts.
