About this study

Official title: Proof of Concept Clinical Trial of Gene Therapy GVB-2001 Delivered Via Intracameral Injection for the Treatment of Primary Open Angle Glaucoma

This is an investigator initiated, single center, open label, non-randomized, exploratory clinical study. The purpose is to assess the safety and preliminary efficacy of gene therapy GVB-2001 (ScAAV2-dnRhoA) delivered via intracameral injection to the anterior segment of the eye for the treatment of subjects with primary open-angle glaucoma. At least 6 primary open angle glaucoma (POAG) patients with high intraocular pressure (IOP) will be divided into two experimental groups. The first subject was given low-dose treatment, and the follow-up subjects were determined by the Safety Review Committee (SRC). Each experimental group was given low-dose and high-dose drug treatment respectively, and low-dose or high-dose treatment was given. The optimal dose will be selected based on the trial results for future development of GVB-2001.

Safety Review Committee, SRC will be set up for safety assessment of the study. The study subjects included will be 18 to 75 years of age (inclusion) and are diagnosed with primary open-angle glaucoma (POAG) for 1 year or more. Only participants who provide informed consent prior to all screening procedures will be eligible for enrollment into the trial.

Read the detailed description

This research plans to recruit at least 6 high intraocular pressure of primary open-angle glaucoma (POAG) patients in one clinical center and divide into two groups. Three primary glaucoma (POAG) patients with elevated intraocular pressure and no vision in the target eye will be enrolled in trial group 1. They will be divided into two dose groups: low-dose group (n = 1) and high-dose group (n = 2). The safety review committee (SRC) will determine whether to enter the high- dose group after the last subject in the low-dose group has completed the Dose limited toxicity (DLT) assessment. In group 2, 3 primary open-angle (POAG) patients with normal visual acuity and high intraocular pressure will be enrolled. The safety review committee (SRC) will determine whether to enter the low-dose group of trial group 2, and whether to enter the high-dose group of trial group 2, after the completion of the evaluation of DLT in the low-dose group of trial group 1. During the study of trial group 2, the safety review committee (SRC) will determine whether to add another optimized dose group to trial group 2, and determine the optimized therapeutic dose and the number of subjects in the optimized dose group.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GVB-2001-high doseDrug

    GVB-2001 is a self-complementary adeno-associated viral vector (scAAV) injection to deliver human dnRhoA gene to trabecular meshwork cells in patients with primary open angle glaucoma. A single dose of high dose GVB-2001 will be injected intracamerally to the target interventional eye.

  • GVB-2001-low doseDrug

    GVB-2001 is a self-complementary adeno-associated viral vector (scAAV) injection to deliver human dnRhoA gene to trabecular meshwork cells in patients with primary open angle glaucoma. A single dose of low dose GVB-2001 will be injected intracamerally to the target interventional eye.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing GVB-2001-high dose and GVB-2001-low dose in people with Primary Open-Angle Glaucoma (POAG), run by IVIEW Therapeutics Inc. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 4 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Zuliang Yao, MD (+1 609 773 8580, zuliang.yao@iviewinc.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number and proportion of subjects with IOP ≤21mmHg (time frame: Day 28, Day 60, Day 90, 6-Month, and 12-Month after GVB-2001 administration.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 May 2026.
