OculusGen™ Collagen Matrix Implant for Phaco-Trabeculectomy in Primary

Status Completed

Clinical Trial Summary

Frequently glaucoma is not controlled with clinical treatment ("eyedrops") or laser surgery to control your eye pressure. If this raised pressure is sustained over a long period of time it can lead to permanent damage to the optic nerve (glaucoma) and in severe cases it can result in blindness. You also have cataracts, an opacification of the natural lens inside the eye that is impairing your vision. To prevent further vision loss due to glaucoma, your doctor has recommended glaucoma filtration surgery to lower your eye pressure, and cataract surgery at the same time to improve your sight.

The use of the anti-metabolite (Mitomycin-C) during the operation is currently the drug of choice to improve surgical outcome for glaucoma filtration surgery. Mitomycin-C is a potent antiscarring agent that reduces the amount of scar tissue produced after surgery which leads to better control of eye pressure. Although this potent drug is effective in increasing surgical success, its use is related to a higher risk of post surgical complications, some of which are sight threatening.

The Collagen Matrix Implant is a biodegradable implant (absorbed naturally by tissue), made from porcine collagen, which reduces scar tissue formed after glaucoma filtration surgery without the use of Mitomycin-C. This means that you could be less likely to have a failed glaucoma filtration surgery, and consequently, a poor eye pressure control. In addition, the risk of surgical failure may be reduced because with this technique, we will not be using potent drugs. However, the long-term effect of the OculusGenTm implant in glaucoma filtration surgery is not fully known.

The aim of the study is to determine whether the OculusGenTm implant can equal the success rate of Mitomycin-C in controlling eye pressure, without the potentially sight threatening complications associated with Mitomycin use. And at the same time, this study aim to determine if the implant can reduce potential complications related to glaucoma surgery when compared to the combined surgery augmented with anti-proliferative agents.

This study will recruit 66 subjects from patients attending the Singapore National Eye Centre over a period of 12-24 months.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
