DURHAM, N.C. & SEATTLE--(BUSINESS WIRE)--May 22, 2023--Last week, at the 26th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT), leading epigenetic editing company Tune Therapeutics showcased the power and potential of its TEMPO TM genetic tuning platform, by presenting data showing the stable repression of the PCSK9 gene and the effective reduction of LDL-cholesterol levels in non-human primates (NHPs). This data marks a significant waypoint on the path to epigenetic medicine, in that it represents the first demonstration of durable epigenetic gene regulation, in a large animal model, following transient delivery of an epi-editor.
A common therapeutic target for the prevention of cardiovascular disease, it is well established that repressing the PCSK9 gene reduces elevated LDL-cholesterol levels, in turn associated with the formation of artery-clogging plaques. The non-human primate data presented at the ASGCT conference showed that epigenome editing (or genetic tuning) can drive the stable repression of PCSK9 (ongoing past four months) following a single treatment, and without cutting or nicking the DNA, or altering its coding sequence in any way.
