UK-based EpilepsyGTx, a biotech focused on research and development of gene therapies to treat refractory epilepsy, has raised $33 million in a Series A financing to advance its lead program EPY201 through Phase I/IIa trials.

The round included investment from XGEN Venture, the British Business Bank, and an unnamed global biopharma company.
