Connect Biopharma Phase 2 Data Supports Trial Continuation, Bolsters Rademikibart Prospects
Event summary
- Connect Biopharma’s Phase 2 Seabreeze STAT trials for rademikibart, targeting asthma and COPD, will proceed as planned.
- An independent Data Monitoring Committee (DMC) reviewed interim efficacy data and recommended no changes to the trial’s sample size.
- The DMC assessed treatment failure rates, exacerbation rates, and FEV1 changes in at least 50 patients with 28 days of follow-up.
- Connect Biopharma anticipates topline data from the Phase 2 trials mid-2026.
The big picture
The positive interim data for rademikibart represents a key de-risking event for Connect Biopharma, which has been focused on developing a next-generation treatment for inflammatory respiratory diseases. The market for asthma and COPD therapies remains substantial, but competition is fierce, making differentiated efficacy and safety profiles crucial for success. This outcome suggests rademikibart may offer that differentiation, but the Phase 3 trials will be the ultimate test.
