What changed

Intellia announced FDA acceptance of its biologics license application for lonvoguran ziclumeran, or lonvo-z, in hereditary angioedema, with Priority Review and a March 10, 2027 target action date. The investigational treatment uses LNP-delivered CRISPR components for in vivo editing. Application acceptance advances the regulatory process but is not marketing approval and does not guarantee a favorable decision.

Why it may matter

The filing moves in vivo RNA/LNP editing into marketing review, with benefit–risk assessment and long-term follow-up central to the next decision.

The interpretation above is analysis, not a conclusion attributed to the original source.

Moderna reports initial mRNA-2808 T-cell engager results in multiple myeloma

Moderna reported initial Phase 1/2 MyEngage findings for mRNA-2808, which encodes three T-cell engagers. Four confirmed responses occurred among 11 response-evaluable patients.
