The company is headquartered in San Diego, California and currently employs 47 full-time employees. The company went IPO on 2026-02-27. Its technology leverages the targeted RNA delivery platform, which combines the tissue selectivity of monoclonal antibodies (mAbs) and other targeted delivery ligands with oligonucleotides. The company is designed to allow selective targeting of the underlying genetic drivers of disease. Its development pipeline consists of programs that target genetically validated drivers of cardiomyopathy, which include Protein Kinase AMP-Activated Non-Catalytic Subunit Gamma 2 (PRKAG2) and Phospholamban (PLN). Its genetic drivers are associated with PRKAG2 syndrome and PLN cardiomyopathy, which is a genetic heart condition associated with life-threatening forms of heart disease. Its programs are supported by preclinical data, in addition to positive clinical data generated in neuromuscular indications using the same RNA delivery platform technology.
