Official title
A Retrospective Cohort Analysis of the Natural Disease Progression of Patients With Choroideremia in Real-World Clinical Practice
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary objective of this study is to quantify disease progression measured by best corrected visual acuity (BCVA) in the real-world setting among Choroideremia (CHM) participants. The secondary objectives are to describe demographic and baseline clinical characteristics among CHM participants and to match CHM participants in the Intelligent Research in Sight (IRIS®) Registry to Biogen's investigator sponsored trial (IST) study population using propensity score matching.
