In a deal that could bring Avidity Biosciences Inc. $2.3 billion if all milestones are met, Bristol Myers Squibb Co. gained global rights to Avidity’s antibody oligonucleotide conjugates platform to advance up to five genetic cardiovascular targets. Avidity’s technology, which combines the specificity of monoclonal antibodies with the precision of oligonucleotide therapies, aims to address the root cause of diseases that are untreatable with current RNA therapeutics. Its lead internal programs are based on the targeted delivery of RNA into muscle.
