Research summary
Glaucoma is a condition which can affect sight, usually due to build-up of pressure within the eye (high intraocular pressure (IOP)). Glaucoma can be treated with eye drops, laser treatment or surgery, each of which has its own risk. Patient non- compliance using eye drops can be a problem treating high IOP
The Bimatoprost SR (sustained release) formulation is a very small biodegradable, preservative free implant preloaded into a single use applicator which does not require patient self-administration. Bimatoprost is the same active ingredient as the commercially approved LUMIGAN® eye drops.
Bimatoprost SR is placed inside the eye between the cornea and the iris. Once placed, the drug is slowly released for about 3 to 4 months and the implant slowly dissolves in about 12 to 15 months.
The purpose of this study is to look into the safety and duration of effect of two dose strengths of Bimatoprost SR in the treatment of glaucoma or ocular hypertension (high eye pressure).
Participants will be randomised using a 1:1 ratio. Depending on what treatment group the participant is assigned to, they will either receive one of two dose strengths of Bimatoprost SR in one of the eyes (study eye) and in the other eye (fellow eye) the study doctor will decide the most appropriate treatment.
The duration of the study for each participant is approximately 32 months consisting of a screening period of up to 10 days before washout, washout period of up to 42 days before the initial Bimatoprost SR administration, 18-month PRN (as needed) treatment period, plus at least 12 months of extended follow up.
Approximately 300 participants will take part in the study worldwide with 16 participants in the UK.
