- Efficacy Comparison: The latest study reveals that INGREZZA exhibits a VMAT2 occupancy of approximately 76.5%, nearly double that of AUSTEDO XR at 38.3%, indicating a significant therapeutic advantage that may lead to improved clinical outcomes for patients.
- Dosage Analysis: The research compared doses of 40mg and 80mg of INGREZZA against 24mg and 48mg of AUSTEDO XR, demonstrating consistently higher VMAT2 occupancy across all doses for INGREZZA, thereby reinforcing its competitive position in the market.
- Clinical Implications: The high VMAT2 occupancy of INGREZZA aligns with its robust early and sustained efficacy observed in multiple clinical trials, potentially offering patients more effective treatment options, particularly for tardive dyskinesia and Huntington's disease chorea.
- Safety Assessment: All doses of INGREZZA and AUSTEDO XR were generally well tolerated and consistent with their known safety profiles, indicating good safety and tolerability in clinical applications.
