Editas Medicine, Inc. announced that centers are now enrolling the first of two planned pediatric cohorts in the Phase 1/2 BRILLIANCE clinical trial of EDIT-101 following the Independent Data Monitoring Committee (IDMC) endorsement to proceed. The IDMC endorsement is based on an analysis of safety data from the adult low-dose and adult mid-dose cohorts. The Company also announced the completion of dosing of the adult mid-dose cohort. Both the pediatric mid-dose cohort and the adult high-dose cohort will run concurrently. For both cohorts, first dosing is expected this summer and completion is expected in the first half of 2022. EDIT-101 is under development for the treatment of Leber congenital amaurosis 10. The Company plans to present initial clinical data from the BRILLIANCE clinical trial at an upcoming medical meeting and is currently submitting an abstract to the International Symposium on Retinal Degeneration planned for September in Nashville.
