Tune Therapeutics
Turning genes up and down without changing sequence — epigenetic editing taken into early clinical trials.
Phase IEpigenetic editing
In one paragraph
Tune does not change the letters of DNA at all. It changes the chemical marks that tell a cell how loudly to read a gene. Its lead programme aims to silence hepatitis B virus inside liver cells, which would be a durable treatment without any permanent change to the patient's own genome.
Tune Therapeutics develops epigenetic editing using dCas fusions to chromatin-modifying domains. Its lead programme, Tune-401, targets chronic hepatitis B by silencing viral DNA in hepatocytes, and has entered early clinical trials — among the first epigenetic editing programmes to reach patients.
