Mereo inks alvelestat option with Sentynl; runway extended to late 2027

Why it may matterVerify against the original reporting

Licensing deal with a potential $40M upfront plus milestones provides a material optionality value; cash runway extension reduces liquidity risk and supports ongoing trials. Positive regulatory dialogue for setrusumab could unlock additional value, though primary endpoint miss may cap upside; overall, near-term catalysts support a constructive view.
