Profile

Atrium Therapeutics, Inc.RNAHealth Care

Develops targeted, non-viral siRNA medicines for rare genetic cardiomyopathies. Its narrow pipeline includes ATR 1072 for PRKAG2 syndrome and ATR 1086 for PLN cardiomyopathy.

Develops targeted, non-viral siRNA medicines for rare genetic cardiomyopathies. ATR 1072 targets PRKAG2 syndrome, while ATR 1086 targets PLN cardiomyopathy; additional targets remain at the research stage.

Built around a delivery platform that pairs tissue-selective antibodies or other delivery ligands with oligonucleotides, the pipeline seeks to reach heart tissue and address genetic drivers rather than symptoms. The company was separated from Avidity and began Nasdaq trading in 2026.

Near-term execution depends on the planned clinical study of ATR 1072, progress toward an IND for ATR 1086, and continued development of cardiac-tissue delivery.
