Completed · Phase 3

Conditions studied: Choroideremia, X-Linked Retinitis Pigmentosa

In brief

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.
