Upstream Bio's Verekitug Shows Clinically Meaningful Improvements in 79% of Patients in New Phase 2 CRSwNP Data
Summary
Upstream Bio presented new responder analyses from its Phase 2 VIBRANT trial for verekitug in chronic rhinosinusitis with nasal polyps (CRSwNP). The data showed a significant majority of participants achieved clinically meaningful improvements, including 79% for nasal polyp score, 72% for nasal congestion, and 83% for total symptom score.
