Future Outlook

The company expects to initiate Phase 3 trials for verekitug in severe asthma and CRSwNP in the first quarter of 2027, following End-of-Phase 2 meetings with the FDA in mid-2026. Data from the Phase 2 VENTURE trial in COPD is now expected in the second half of 2027, with further enrollment capped to prepare for a Phase 3 trial of a high-dose quarterly regimen.

Management Comments

• "We continue to make strong progress advancing our clinical programs in severe asthma and CRSwNP to position verekitug as a uniquely differentiated treatment option for these diseases," said Rand Sutherland, MD, Chief Executive Officer of Upstream Bio.
• "We are working diligently to deliver best-in-class efficacy with convenient quarterly at-home dosing, a profile that we believe will advance the standard of care for patients and maximize the potential commercial value of verekitug."
• "Given our goal to deliver the best efficacy profile possible in all three indications, including COPD, we intend to cap further enrollment in VENTURE as we begin preparations for a Phase 3 trial of a high-dose quarterly regimen in COPD."
• "Across our programs, we remain focused on disciplined execution and generating the data needed to bring a meaningful new treatment option to patients as quickly as possible."

Key Dates

Recommendation

The company is making steady progress in its core severe asthma and CRSwNP programs, with clear timelines for Phase 3 initiation. However, the delay in COPD data and the increasing net loss warrant a cautious 'hold' rating until further clarity on the COPD trial and overall financial runway is provided.
