The company has developed a proprietary gene editing platform based on CRISPR technology that includes CRISPR/Cas9, CRISPR/Cas12a, engineered forms and foundational intellectual property for both CRISPR systems. CRISPR uses a protein-RNA complex composed of an enzyme, including either Cas9 (CRISPR-associated protein 9) or Cas12a (CRISPR from Prevotella and Francisella 1, also known as Cpf1), bound to a guide RNA molecule designed to recognize a particular DNA sequence. The company is engaged in discovering, developing, manufacturing, and commercializing durable, precision in vivo gene-editing medicines for a broad class of diseases. Vivo medicines include vivo editing of hematopoietic stem cells (HSCs), liver cells and other tissues. Vivo gene editing in HSCs supports the advancement of research programs to treat non-malignant hematological diseases.
