A Pilot Study to Assess Safety and Efficacy of Intraoperative Topical Mitomycin C and Bevacizumab (Avastin) Applied to Bare Sclera in Pterygium Surgery
In Brief
A Phase 2 clinical trial evaluating Bevacizumab and Mitomycin C for Pterygium. Completed, enrolled 51 participants across 2 sites.
Detailed Summary
This study will evaluate the efficacy and safety of the use of bevacizumab (Avastin) as an adjunctive medication during pterygium surgery in preventing pterygium recurrence. A pterygium is a white fleshy growth on the surface of the eye, which can be removed surgically. However, after surgical removal, pterygia can recur. One way of minimizing recurrence is by applying a medication called mitomycin C to the surface of the eye during pterygium surgery. However, mitomycin is associated with certain side effects, such as thinning of the eye wall and poor wound healing. Bevacizumab has a different mechanism of action and there is some evidence that it may be useful in preventing pterygium recurrence. In this study, the safety and efficacy of adjunctive intraoperative use of bevacizumab and mitomycin C for preventing pterygium recurrence will be directly compared.

Timeline
Interventions
1.25 mg/mL applied one time intraoperatively using bevacizumab-soaked filter paper manually applied to bare sclera during pterygium surgery for 2 minutes, followed by copious rinsing with balanced salt solution.
Mitomycin C 0.02% will be applied to bare sclera during pterygium surgery using a medication-soaked filter paper for a duration of two minutes. After medication administration, the ocular surface will be copiously irrigated with balanced salt solution.
