- Clinical Trial Results: In the VIBRANT trial, verekitug demonstrated a significant reduction of 0.9 in ACQ-6 scores among CRSwNP patients with comorbid asthma, indicating its potential to improve asthma symptom control and possibly change treatment standards.
- Nasal Polyp Improvement: Verekitug effectively reduced nasal polyp scores over 24 weeks, with greater improvements in sinonasal symptoms such as nasal congestion and total symptom scores observed in patients with comorbid asthma, highlighting its importance in managing multiple symptoms.
- Biomarker Changes: Verekitug led to significant reductions in type 2 inflammatory cytokines like IL-4, IL-5, and IL-13 in both blood and nasal secretions, with a 50% decrease in blood eosinophils, demonstrating its effectiveness in inflammation control.
- Reduced Treatment Needs: Among patients with comorbid asthma, verekitug reduced the need for rescue systemic corticosteroids or CRSwNP surgery by 83%, alleviating patient treatment burdens and potentially lowering healthcare costs.

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.
