Chronic Ocular Pain Clinical Trial
Official title:
A 12-week Parallel Group, Randomized, Placebo-controlled, Double-blinded, Multi-center Study to Evaluate Efficacy and Safety of 2 Concentrations of SAF312 Eye Drops (5 mg/ml and 15 mg/ml) Used Twice-daily in the Treatment of Post-operative Corneal Induced Chronic Pain (CICP) Following Photorefractive Keratectomy (PRK) or Laser-assisted in Situ Keratomileusis (LASIK) Surgeries
The study was designed to demonstrate the safety and efficacy of two dose concentrations of SAF312 eye drops (5 mg/mL and 15 mg/mL) in subjects with CICP persisting at least for 4 months after refractive or cataract surgery and chronicity confirmed during the observational period. The study also determined the optimal dose to carry forward for further development.
This was a Phase II randomized, double-masked, multi-center, parallel group, placebo-controlled study to evaluate the safety and efficacy of SAF312, 5 mg/mL and 15 mg/mL eye drops versus Placebo used twice-daily in both eyes for 12 weeks. The study consisted of a 12-week observation period starting from Screening Visit (Visit 1) until the Baseline/Randomization Visit (Visit 2). Subjects who met eligibility criteria at Visit 2 were randomized to one of the three treatment arms (SAF312 5 mg/mL, SAF312 15 mg/mL, Placebo) in a 1:1:1 ratio. Subjects who qualified for randomization had visits every 2 weeks for the first 4 weeks, and then monthly visits for the remainder of the 12-week treatment period. ;
