Bimatoprost Ocular Insert Compared to Topical Timolol Solution in Patients With Glaucoma or Ocular Hypertension

Phase 2

Completed

Interventions: Drug: Timolol 0.5%
Drug: Bimatoprost
Drug: Placebo Eye Drops
Device: Placebo Ocular Insert

Brief Summary: The objective of this Phase 2 study is to evaluate whether the Bimatoprost Ocular Insert is non-inferior to that of timolol ophthalmic solution (0.5%) at 12 weeks.

13 mg Bimatoprost Ocular Insert	Placebo Ocular Insert	Washout and placebo ocular insert in each eye for at least 4 weeks, followed by 13 mg Bimatoprost Ocular Insert in each eye and placebo eye drops twice a day in each eye for 6 months.
Timolol 0.5% + Placebo Ocular Insert	Placebo Ocular Insert	Washout and placebo ocular insert in each eye for at least 4 weeks, followed by Timolol (timoptic ophthalmic solution 0.5%) twice a day in each eye plus placebo ocular insert for 6 months.
13 mg Bimatoprost Ocular Insert	Placebo Eye Drops	Washout and placebo ocular insert in each eye for at least 4 weeks, followed by 13 mg Bimatoprost Ocular Insert in each eye and placebo eye drops twice a day in each eye for 6 months.
13 mg Bimatoprost Ocular Insert	Bimatoprost	Washout and placebo ocular insert in each eye for at least 4 weeks, followed by 13 mg Bimatoprost Ocular Insert in each eye and placebo eye drops twice a day in each eye for 6 months.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Intra-Ocular Pressure (IOP) at Week 2	Baseline (Day 0) to Week 2	IOP is a measurement of the fluid pressure inside the eye. Diurnal IOP measurements were taken at 8 am (time (T)=0 hour), 10 am (T=2 hour), and 4 pm (T=8 hour) at Week 2. IOP readings from both eyes were averaged to compute a single IOP value for each diurnal timepoint. A negative change from Baseline indicated improvement.
Change From Baseline in Intra-Ocular Pressure (IOP) at Week 6	Baseline (Day 0) to Week 6	IOP is a measurement of the fluid pressure inside the eye. Diurnal IOP measurements were taken at 8 am (T=0 hour), 10 am (T=2 hour), and 4 pm (T=8 hour) at Week 6. IOP readings from both eyes were averaged to compute a single IOP value for each diurnal timepoint. A negative change from Baseline indicated improvement.
Change From Baseline in Intra-Ocular Pressure (IOP) at Week 12	Baseline (Day 0) to Week 12	IOP is a measurement of the fluid pressure inside the eye. Diurnal IOP measurements were taken at 8 am (T=0 hour), 10 am (T=2 hour), and 4 pm (T=8 hour) at Week 12. IOP readings from both eyes were averaged to compute a single IOP value for each diurnal timepoint. A negative change from Baseline indicated improvement.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in IOP at Month 4	Baseline (Day 1) to Month 4	IOP is a measurement of the fluid pressure inside the eye. Diurnal IOP measurements were taken at 8 am (T=0 hour), 10 am (T=2 hour), and 4 pm (T=8 hour) at Month 4. IOP readings from both eyes were averaged to compute a single IOP value for each diurnal timepoint. A negative change from Baseline indicated improvement.
Change From Baseline in IOP at Month 5	Baseline (Day 0) to Month 5	IOP is a measurement of the fluid pressure inside the eye. Diurnal IOP measurements were taken at 8 am (T=0 hour), 10 am (T=2 hour), and 4 pm (T=8 hour) at Month 5. IOP readings from both eyes were averaged to compute a single IOP value for each diurnal timepoint. A negative change from Baseline indicated improvement.
Change From Baseline in IOP at Month 6	Baseline (Day 0) to Month 6	IOP is a measurement of the fluid pressure inside the eye. Diurnal IOP measurements were taken at 8 am (T=0 hour), 10 am (T=2 hour), and 4 pm (T=8 hour) at Month 6. IOP readings from both eyes were averaged to compute a single IOP value for each diurnal timepoint. A negative change from Baseline indicated improvement.
