Clinical trial

A Clinical Study on CRISPR/Cas9 Instantaneous Gene Editing Therapy to Primary Open-angle Glaucoma With Elevated Intraocular Pressure and MYOC Gene Mutation

Name
BD-MMG-113001
Description
This study will be intented to evaluate the safety and tolerability 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 preliminary metabolism characteristics of BD113vLVP in participants.

Treatment
CRISPR/Cas9 mRNA instantaneous gene editing technology
CRISPR/Cas9 gene editing technology (BD113vVLP) is used to knock out the mutated MYOC gene. The BD113 virus-like particle (vVLP), modified from the third-generation integrated defective lentivirus, is used to deliver gRNA/Cas9 ribonucleoprotein complex (RNP). Single dosing with 4ug/p24 by intracamerally injecton for each target interventional eye.
Arms:
Group 1: POAG without vision for interventional eye, Group 2: POAG with vision for interventional eye
Other names:
BD113vVLP, BD113 virus-like particle
