Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals diagnosed with glaucoma or other specified optic neuropathies who can provide informed consent.

Probably not a fit

Patients with other ocular pathologies contributing to severe vision loss or those with diabetes may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 1 trial aims to evaluate the safety of topical sterile human recombinant insulin in patients with optic neuropathies, including glaucoma, over a period of 1-2 months. Participants will receive varying doses of insulin applied to the affected eye, with the goal of assessing any adverse effects. The study will focus on one eye per patient, specifically selecting the eye with the worse visual acuity or visual field. The trial will help determine if insulin can be a viable treatment option for patients suffering from these conditions.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with glaucoma and other optic neuropathies.

How similar studies have gone: While this approach is novel, similar studies exploring insulin's effects on ocular conditions have shown promise, but this specific application is less tested.
