(Nasdaq: UPB), a clinical-stage company developing treatments for inflammatory diseases, with an initial focus on severe respiratory disorders, today reported financial results for the first quarter ended March 31, 2025, and provided a summary of recent business highlights. The Company is developing verekitug, the only monoclonal antibody currently in clinical development that targets and inhibits the thymic stromal lymphopoietin (TSLP) receptor, in multiple severe respiratory diseases including chronic rhinosinusitis with nasal polyps (CRSwNP), severe asthma and chronic obstructive pulmonary disease (COPD). “This quarter we made excellent progress in our development of verekitug, positioning us well to deliver on our upcoming clinical milestones. We are pleased to accelerate our guidance on several near-term events, including the top-line data readout from our Phase 2 clinical trial of verekitug in patients with CRSwNP, expected in the third quarter of this year,” said Rand Sutherland, MD, Chief Executive Officer of Upstream Bio. “In addition, we now anticipate reporting top-line data from our Phase 2 clinical trial in severe asthma in the first half of 2026. We also now expect to dose the first patient in our Phase 2 clinical trial in COPD in mid-2025. We look forward to sharing further updates as we reach these key milestones.” Dr. Sutherland continued, “Verekitug is the only known molecule currently in clinical development targeting the TSLP receptor. Early clinical data suggest that this unique mechanism of action has the potential to meaningfully impact disease activity in patients with these severe respiratory diseases through both differentiated efficacy and an extended dosing interval, and we are testing the therapeutic implications of these observations across our development programs.” First Quarter 2025 and Recent Business Highlights Top-...
