Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)

Following the end of the study as defined in the protocol, per health authority requirements, all patients who either complete or prematurely discontinue from the study are to be followed up to 15 years post-PHE885 administration. Therefore, a post-study long-term follow-up for lentiviral vector safety monitoring will continue under a separate protocol (CCTL019A2205B).
