What the changes say
- PROSERA missed its primary endpoint, putting seralutinib’s FDA path, further trials, financing needs, and commercialization in doubt.
- Workforce reduction eliminated approximately 77 employees, or 48% of staff, to preserve cash but threatens capabilities and morale.
- Regulatory, clinical-trial, reimbursement, collaboration, patent, and manufacturing risks remain concentrated around seralutinib.
- New tariff and import/export uncertainty adds a broader operating risk.

The results from the PROSERA Phase 3 clinical trial may not be sufficient to support FDA approval or continued development of seralutinib, which would materially and adversely harm our business
PROSERA failed its primary endpoint, and FDA feedback could require more studies, delay approval, or eliminate a viable path for seralutinib.
