Pipeline and Publications

Our goal: To employ our proprietary product engine to systematically identify and validate cellular drug targets that can modulate gene expression to treat the known root cause of genetically defined diseases.


Broad potential to change lives

Our approach to drug discovery and development is applicable across a large number of genetically defined diseases. We have developed a rigorous assessment and selection process to determine which of the approximately 7,000 rare, genetically defined diseases we intend to evaluate in drug target identification activities. We are applying our product engine to discover drug targets to modulate gene expression and develop product candidates for the potential treatment of the root cause of these diseases.
