Why it matters

Respiratory biologics are moving into broader asthma, CRSwNP, COPD and acute-exacerbation settings.
Inhaled and intranasal delivery remained a clear theme, spanning hydrogels, ASOs, pirfenidone and innate immune modulators.
Several updates were enrollment or study-readiness milestones, setting up readouts from Q3 2026 through H2 2027.
Commercial access activity continued, with GSK’s Canadian approval and Innoviva’s regional XACDURO licensing deal.
Fibrosis programs were prominent, including Simcere’s exploratory IPF work and Avalyn’s PPF Phase 2b milestone.
