Study Summary

This study is intented to evaluate the safety, tolerability and preliminary efficacy of CRISPR/Cas9 Instantaneous Gene Editing Therapy (BD113 virus-like particle, also BD113vLVP) in patients with primary open-angle glaucoma (POAG) with elevated intraocular pressure and MYOC gene mutation. The main objectives to evaluate the safety and tolerability BD113vLVP) in POAG patients with intraocular hypertension and MYOC mutation, and secondary objectives is to explore the preliminary efficacy and the metabolism characteristics of BD113vLVP in participants.

Study Description

This is an open, single-dose, two-arm, non-randomised clinical study. A total of 6 to 9 POAG patients with high intraocular pressure were enrolled and divided into two test groups. Test Group 1 recruits 3 POAG patients, who have elevated IOP and positive or negative MYOC mutation and target interventing eye is no vision. Test Group 2 will recruit 3 to 6 POAG patients with MYOC mutations and visual acuity. In order to better verify the lowering IOP effectiveness of BD113vVLP, another 2 or 3 participants will be recruied in Group 2 on-demand. Each participant will receive single dosing BD113vVLP (4µg p24) by intracameral injection in the interventing eye, then conduct the evaluations of the safety and efficacy according to visit schedule in 1 year follow-up。
