Dose-Ranging Study of the Bimatoprost Ocular Insert

A Phase 2 Prospective, Multicenter, Randomized, Double-masked, Controlled Study to Evaluate the Efficacy and Safety and Dose-response of the Bimatoprost Ocular Insert (2.2 mg, 13 mg) With and Without Concomitant Artificial Tears Compared to a Placebo Ocular Insert With and Without Concomitant Timolol (0.5%) Ophthalmic Solution in Patients With Open-angle Glaucoma or Ocular Hypertension

The Bimatoprost Ocular Insert is intended to provide sustained delivery of bimatoprost to the ocular surface to lower the intraocular pressure (IOP) in patients with Open-Angle Glaucoma or Ocular Hypertension.

This study evaluated the safety and efficacy of two different doses of the Bimatoprost Ocular Insert, compared to an active control arm with timolol ophthalmic solution (0.5%).

Key Inclusion Criteria:

Inclusion Criteria at the Randomization Visit:

("T" is defined as time and "hr" is defined as hour[s])

• IOP for each eye is ≥ 23 mm Hg at T=0 hr, ≥ 20 mm Hg at T=2 hr and T=8 hr.
• Inter-eye IOP difference of ≤ 5.0 mm Hg at T=0 hr, T=2 hr and T=8 hr.
• IOP for each eye is ≤ 30 mm Hg at T=0 hr, T=2 hr and T=8 hr.

Key Exclusion Criteria:

• Any known contraindication to prostaglandin analog (latanoprost, travoprost, bimatoprost, tafluprost) or timolol
• A cardiac or pulmonary condition that in the opinion of the Investigator would contraindicate the use of beta-blocker drops

• Laser surgery for glaucoma / ocular hypertension on one (1) or both eyes within the last six (6) months
• Past history of any incisional surgery for glaucoma at any time
• Past history of corneal refractive surgery

• Inability to adequately evaluate the retina
• Participants who will require contact lens use during the study period.
• Participants who currently have punctal occlusion
• Pregnant, lactating or of child-bearing potential and not using a medically acceptable form of birth control
