Therapeutic modulation of the epigenome presents significant opportunities to control and resolve gene dysregulation across diseases, if applied in a highly precise, specific, and tunable manner.Omega Therapeutics is enabling programmable epigenomic mRNA therapeutics through an innovative platform utilizing lipid nanoparticles (LNP) with mRNA encoded epigenomic controllers (EC) capable of site-specific, controllable, and durable epigenetic modifications to treat disease.Novel LNPs that can access relevant tissue and cellular targets are designed to have unique compositions and formulation requirements that must be optimized to advance program development and enable clin. meaningful outcomes.Omega has built key expertise in LNP development that supports our novel EC-mRNA platform.We will provide a summary of key CMC strategies for formulation, stability, identity, and potency testing.Omega's success in LNP development and CMC has led to clin. evaluation of the first novel EC-mRNA-LNP for the treatment of hepatocellular carcinoma (HCC) that targets the MYC oncogene.Continuous development and innovation in drug product manufacturing, DS/DP and formulation process and anal. development enables the advancement of a pipeline of novel epigenomic controllers across a variety of therapeutic areas.
