About
Atrium Therapeutics is a San Diego-based precision cardiology biotech that began trading on Nasdaq under ticker RNA on February 27, 2026, established as an independent spinoff in connection with Novartis AG's acquisition of Avidity Biosciences. The company develops RNA medicines for rare, life-threatening genetic cardiomyopathies, using a targeted delivery platform that couples the tissue selectivity of monoclonal antibodies and other ligands with siRNA payloads delivered directly to heart tissue. Its two lead development candidates are ATR-1072 for PRKAG2 syndrome and ATR-1086 for phospholamban (PLN) cardiomyopathy, alongside two undisclosed research-stage targets. Atrium launched with approximately $270 million in cash and cash equivalents and is led by President and CEO Kathleen Gallagher.
