Brief Title ICMJE | Long-term Safety and Efficacy Follow-up of BIIB111 for the Treatment of Choroideremia and BIIB112 for the Treatment of X-Linked Retinitis Pigmentosa | ||||
Official Title ICMJE | A Long-term Follow-up Study to Evaluate the Safety and Efficacy of Retinal Gene Therapy in Subjects With Choroideremia Previously Treated With Adeno-Associated Viral Vector Encoding Rab Escort Protein-1 (AAV2-REP1) and in Subjects With X-Linked Retinitis Pigmentosa Previously Treated With Adeno-Associated Viral Vector Encoding RPGR (AAV8-RPGR) in an Antecedent Study | ||||
Brief Summary | The objective of the study is to evaluate the long-term safety and efficacy of a sub-retinal injection of BIIB111 in participants with Choroideremia (CHM) who have been previously treated with BIIB111 and who have exited an antecedent study; these treated participants will be compared with untreated control participants who have exited the STAR (NCT03496012) study and BIIB112 in participants with X-linked retinitis pigmentosa (XLRP) who have been previously treated with BIIB112 and who have exited an antecedent study. | ||||
