Why it may matterVerify against the original reporting
Positive Phase 2a topline data reduces clinical risk, supports further development milestones (OLE data, 52-week readouts), and strengthens regulatory-path visibility. Cash runway improvements from the $200M offering reduce near-term dilution concerns; similar past biotech data-readthroughs have driven multi-quarter upside as milestones approach.
