Bimatoprost SR Met the Primary Endpoint of Noninferiority to Timolol BID in IOP Lowering Through Week 12*

*Both 10 µg and 15 µg doses met the primary endpoint. Upper limit of 95% confidence interval of Bimatoprost SR − timolol difference was <1 mm Hg at Hours 0 and 2 at Weeks 2, 6, and 12 in each study, as well as in the pooled study dataset.

BID, twice daily; Bimatoprost SR, bimatoprost sustained-release implant; IOP, intraocular pressure; W, weeks.

Primary Efficacy Results:

Mean IOP

• Mean diurnal IOP consistently

maintained between 16–17

mm Hg

• During the primary efficacy

period, IOP lowering was

numerically greater with

Bimatoprost SR than timolol at

all 6 time points

y• First-in-class sustained-release, biodegradable implant for the treatment of open-angle

glaucoma or ocular hypertension designed to lower IOP for at least 4 months while freeing patients from daily eye drop regimens

• In P3 and P1/2 studies, BimSR demonstrated an extended duration of effect of 1 year (83%) or 2 years (36%) in many patients

• Sustained IOP lowering may involve durable MMP-mediated remodeling of aqueous outflow

• The value of extended duration of effect is reduced treatment burden, improved adherence with more sustained pressure lowering, less hyperemia, less orbitopathy

• Empowers physicians by putting IOP control in their hands

Bimatoprost SR Risk/Benefit was favorable in both Phase 3 studies
