Merck's WINREVAIR Achieves Key Clinical Trial Milestone
- Clinical Trial Success: Merck's WINREVAIR met its primary endpoint in the CADENCE study, showing a significant reduction in pulmonary vascular resistance (PVR) with a 1.02 Wood unit decrease in the 0.3 mg/kg dose group and a 0.75 Wood unit decrease in the 0.7 mg/kg group, indicating potential therapeutic effects for this specific patient population.
- Advancement to Registration Study: The totality of evidence from the CADENCE study supports Merck's plan to advance WINREVAIR into a registrational Phase 3 study, aiming to provide the first treatment option for patients with CpcPH-HFpEF, addressing an urgent medical need.
- Improvements in Secondary Endpoints: In secondary endpoints, the 0.3 mg/kg dose group showed a 20.3-meter increase in six-minute walk distance (6MWD), alongside significant reductions in mean pulmonary arterial pressure (mPAP) and NT-proBNP levels, further supporting the clinical application potential of WINREVAIR.
- Patient Demographics Analysis: The CADENCE study enrolled 164 participants with a median age of 75 years, 69.5% female, and 65.9% classified as NYHA functional class III, highlighting the drug's relevance and applicability in older patient populations.
