Oxford Biomedica notes announcement that FDA has lifted clinical hold on Homology Medicines' pheNIX trial

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. As Homology previously disclosed, it received official notice of the clinical hold on March 17, 2022 and it pertained to elevated liver function tests observed in the trial, which were all resolved with no hospitalizations required. Homology's response to the FDA included changes to the protocol intended to enhance risk-mitigation measures, including a steroid-sparing immunosuppression regimen.
