Upstream Bio Inc. has released a corporate presentation detailing recent progress in its clinical-stage immunology programs focused on severe respiratory diseases. The company highlighted the completion of the Phase 2 VIBRANT trial evaluating verekitug in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Verekitug met its primary endpoint, achieving a reduction in nasal polyp score (NPS) of -1.8 (p<0.0001), and demonstrated key secondary benefits, including a reduction in need for surgery or steroids by 76% (p=0.03). The treatment was generally well tolerated, with no serious adverse events reported. Additional Phase 2 studies are underway, including VALIANT in severe asthma, with top-line results expected in Q1 2026, and VENTURE in COPD, which is currently enrolling participants.
