What this trial studies

This Phase III study evaluates the pharmacokinetics and safety of 0.002% DE-117B eye drops in patients diagnosed with primary open angle glaucoma or ocular hypertension. Participants will undergo a washout of their current intraocular pressure (IOP) lowering medications before receiving the treatment. The study includes a single-arm, open-label cohort and a randomized, evaluator-masked, active drug-control multicenter component. The treatment will be administered once daily for seven days, and there will be a follow-up phase to monitor outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with primary open angle glaucoma or ocular hypertension who meet specific eligibility criteria.

Not a fit: Patients with severe visual field disorders or other significant ocular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for managing glaucoma and ocular hypertension.

How similar studies have performed: Other studies have shown success with similar pharmacological approaches in treating glaucoma, indicating potential for this treatment.
