Embargo Breach Prompted Early Disclosure
Draft posters were inadvertently made publicly available via the ERS website before the embargo expired, prompting the company to furnish final posters as Exhibit 99.1.
-
Next Milestone: ERS Congress Presentation
The posters are scheduled for presentation at the European Respiratory Society Congress 2026, September 5-9, 2026, with the embargo lifting at 6:01 p.m. ET on September 7, 2026.
Analysis · GENB · Life Sciences
The 8-K discloses final posters for the ERS Congress 2026 after draft versions leaked early. The data show GB-0895, a next-generation anti-TSLP antibody, achieved a ~98-day half-life and durable reductions in key asthma and COPD biomarkers for at least 6 months with a favorable safety profile. The company also revealed the design of two Phase 3 registrational studies (SOLAIRIA-1 and SOLAIRIA-2) in severe uncontrolled asthma. This is the first public disclosure of these clinical results and trial designs, and it materially de-risks the lead program ahead of the ERS presentation on September 7, 2026.
