Open Angle Glaucoma study: ER-100 epigenetic therapy
Official title Evaluating ER-100 for Safety in People With Glaucoma or Non-Arteritic Anterior Ischemic Optic Neuropathy (Optic Nerve Conditions)
ClinicalTrials.gov ID: NCT07290244
What this study is testing
What is ER-100?
ER-100 is an investigational eye injection being studied as a potential treatment for Open Angle Glaucoma. It is designed to use a modified virus to deliver instructions that help reverse age-related changes in retinal cells.
Also referred to as OSK epigenetic therapy.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if ER‑100 is safe and well tolerated in people with these optic nerve conditions and to identify any side effects.
- Who it's for
- Adults who have open angle glaucoma or non‑arteritic anterior ischemic optic neuropathy.
- What's involved
- Participants will receive one dose of ER‑100, have detailed eye exams and lab tests, give samples of tears, saliva, feces and urine, and fill out quality‑of‑life questionnaires.
- Time commitment
- The study lasts up to 5 years, with visits for safety checks and follow‑up assessments during that time.
- Phase 1: an early, usually small safety study
- Time commitment: about 5 years

- If only one eye is affected, there must be a difference in pupil response between the two eyes.
- Have vision in the affected eye between 20/40 and 2/500 on a standard eye chart.
- History of optic neuritis (inflammation of the optic nerve) or repeated episodes of eye inflammation (uveitis) not caused by injury or surgery.
- Allergic reactions to tetracycline antibiotics or steroid medications.
- Moderate to severe cataracts, macular problems, or corneal issues that could interfere with eye testing.
- Unable to keep your eyes focused on a target during testing.
