AI Summary
Invivyd announced completion of enrollment in the DECLARATION Phase 3 trial evaluating VYD2311 for COVID-19 prevention, with topline results targeted for late Q3 2026. The study includes single-dose and monthly-dosing arms and was upsized by ~500 subjects to boost statistical power amid variable COVID rates. Positive results could support a potential BLA submission and expanded protection options for high-risk populations.
Sentiment Rationale
Positive trial progression and a concrete topline readout window typically lift biotech stocks. Upsizing to boost power reduces trial risk, increasing the probability of favorable results and potential BLA timing.
