INGREZZA's Breakthrough in Huntington's Disease Chorea#

Clinical Milestones and Market Potential#

INGREZZA has recently achieved a pivotal milestone in the treatment of Huntington's Disease (HD), specifically for chorea, the involuntary, jerky movements characteristic of the condition. In August 2023, the U.S. Food and Drug Administration (FDA) approved INGREZZA for the treatment of HD chorea, marking it as the first VMAT2 inhibitor explicitly sanctioned for this indication Market projections for Huntington's Disease treatments. This approval positions INGREZZA as a critical alternative to existing therapies, notably Teva Pharmaceuticals' Austedo.

Market analyses highlight the significant potential of this expanded indication. The HD treatment market is projected to expand from approximately $1.41 billion in 2024 to an estimated $4.27 billion by 2033, demonstrating a robust compound annual growth rate (CAGR) of +10.34% Market projections for Huntington's Disease treatments. With an addressable U.S. patient population of around 23,000 individuals suffering from HD chorea, NBIX anticipates potential revenues from this indication to exceed $500 million by 2030. In 2024, INGREZZA sales are expected to surpass $2 billion, bolstered by its convenient once-daily dosing and a favorable tolerability profile, which are key differentiators in patient compliance and physician preference.

Competitive Dynamics with Austedo#

While Teva's Austedo (deutetrabenazine) remains a formidable competitor in the HD chorea space, INGREZZA's recent FDA approval specifically for HD chorea, coupled with emerging clinical data, provides a competitive edge. Post-hoc analyses from the KINECT-HD study, released on June 27, 2025, demonstrated that INGREZZA not only effectively reduces chorea but also shows promising indications of alleviating cognitive and broader motor disease burden. This broader impact on patient function could significantly enhance INGREZZA's therapeutic appeal and market share, moving beyond mere symptom control to a more holistic improvement in patient quality of life Market projections for Huntington's Disease treatments.
