About UPB
Upstream Bio, Inc. is a clinical-stage biotechnology company developing treatments for inflammatory diseases, with an initial focus on severe respiratory disorders. The Company is developing verekitug, the only known antagonist in clinical development, that targets the receptor for thymic stromal lymphopoietin (TSLP), a cytokine which is a clinically validated driver of inflammatory response positioned upstream of multiple signaling cascades that affect a variety of immune mediated diseases. It has advanced this highly potent monoclonal antibody into separate phase II trials for the treatment of severe asthma and chronic rhinosinusitis with nasal polyps and plans to initiate development in chronic obstructive pulmonary disease. TSLP is a member of a class of epithelial cytokines, also including IL-25 and IL-33, commonly referred to as alarmins. TSLP is primarily produced by epithelial cells, especially in the lung, gastrointestinal tract and skin.

Upstream Bio Presents New Data from VIBRANT Trial
- Primary Endpoint Improvement: In the VIBRANT clinical trial, verekitug achieved a reduction in endoscopic nasal polyp score (NPS) of -1.95 (p < 0.0001) over 24 weeks, demonstrating significant efficacy in treating chronic rhinosinusitis with nasal polyps (CRSwNP), which could potentially redefine treatment standards.
- Strong Secondary Endpoint Results: The trial also showed a nasal congestion score (NCS) reduction of -0.96 (p < 0.0001), compared to -0.77 (p = 0.0003) in the primary analysis, further validating verekitug's clinical benefits and potentially attracting more patients for future treatments.
- Surgery Demand Reduction: The verekitug treatment group saw a 76% reduction (p = 0.03) in the need for surgery or systemic corticosteroids, indicating its potential to lessen patients' reliance on invasive treatments, which may enhance their quality of life.
- Future Trial Planning: Upstream Bio plans to initiate Phase 3 trials in CRSwNP and severe asthma, with verekitug's unique mechanism of action and less frequent dosing positioning it as a new treatment option, thereby enhancing the company's market position in respiratory diseases.
