Investment Insights

Positive Market Indicators

• Strong Clinical Data: Sonelokimab demonstrated clinically meaningful and statistically significant benefits in its Phase 2 PPP trial and positive interim data in Phase 3 HS trials.
• Clear Regulatory Path: A scheduled Type B meeting with the FDA to discuss a BLA submission is a critical step towards commercialization.
• Solid Financial Runway: The company is well-capitalized to fund operations through its many upcoming catalysts in 2026 and into 2027.
• Dense Catalyst Calendar: Multiple data readouts and regulatory milestones are expected over the next 12-18 months, providing numerous potential value inflection points.

Risk Factors

• Clinical Risk: Future and ongoing trials, including the full data readouts, still carry inherent risks of not meeting endpoints.
• Competition: The inflammatory disease space is competitive, and Sonelokimab will need to demonstrate a competitive advantage upon potential approval.
