Is Phase 4 Success Altering The Investment Case For Neurocrine Biosciences Stock?

Neurocrine Biosciences reported Phase 4 KINECT-PRO data showing INGREZZA's effectiveness in treating tardive dyskinesia, leading to raised full-year guidance. The company also highlighted portfolio additions CRENESSITY and VYKAT XR. Analysts note that INGREZZA's demand resilience and patient-reported benefits support the investment case, but payer pressure and Medicare negotiations remain risks. Analysts project $5.2B in revenue and $1.4B in earnings by 2029, with a potential 46% upside.
