Oxford, UK – 14 June 2022: Oxford Biomedica plc (LSE:OXB) (“Oxford Biomedica” or “the Company”), a leading gene and cell therapy group, notes the recent announcement from Homology Medicines Inc. (Nasdaq: FIXX) (“Homology”), a genetic medicines company regarding the pheNIX gene therapy trial.

The U.S. Food and Drug Administration (FDA) has notified Homology that the clinical hold on its pheNIX gene therapy trial of HMI-102 in adults with phenylketonuria (PKU) has been lifted.
