Enanta Pharmaceuticals’ share price gain can likely be attributed to the growing investor sentiment in the company’s advancing pipeline, particularly in respiratory syncytial virus (RSV) and immunology programs. Enanta is now conducting phase III-enabling activities for its lead RSV candidate, zelicapavir, with the FDA while also exploring partnership opportunities. Recent progress in the company’s immunology pipeline, including the dosing of the first participant in the phase I study of EDP-978, a KIT inhibitor being developed for urticaria and other type II inflammatory diseases, also boosted investor confidence.
