About this study

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline at Week 12 in Ocular Pain Severity Visual Analog Scale (VAS)

    The pain severity Visual Analogue Scale (VAS) was completed by the subject using an electronic diary. A vertical mark was placed on the horizontal scoring line (anchored with 'No Pain' on the left and 'Very Severe' pain on the right) to score the severity of ocular pain over the past 24 hours, with a range from 0 (min) to 100 (max). Higher scores indicate higher pain severity. A negative change from baseline is a positive outcome.

    Measured: Baseline, Week 12

Secondary outcomes (16)
  1. Ocular Pain Severity Visual Analog Scale (VAS): Summary Statistics of Change From Baseline at Day 7 and Day 14

    The pain severity Visual Analogue Scale (VAS) was completed by the subject using an electronic diary. A vertical mark was placed on the horizontal scoring line (anchored with 'No Pain' on the left and 'Very Severe' pain on the right) to score the severity of ocular pain over the past 24 hours, with a range from 0 (min) to 100 (max). Higher scores indicate higher pain severity. A negative change from baseline is a positive outcome.

    Measured: Baseline, Days 7 and 14

  2. Ocular Pain Frequency Visual Analog Scale (VAS): Summary Statistics of Weekly Mean Change From Baseline to Week 12

    The pain frequency Visual Analogue Scale (VAS) was completed by the subject using an electronic diary. A vertical mark was placed on the horizontal scoring line (anchored with 'No Pain' on the left and 'Very Frequent' pain on the right) to score the frequency of ocular pain over the past 24 hours, with a range from 0 (min) to 100 (max). Higher scores indicate higher pain frequency. A negative change from baseline is a positive outcome.

    Measured: Baseline, Weeks 1 to 12

  3. Ocular Pain Assessment Scale (OPAS) Subscale Quality of Life: Summary Statistics of Change From Baseline to Week 12

    Each question in the Ocular Pain Assessment Survey (OPAS) quality of life subscale was scored by the subject on a line marked from 0 (not at all) to 10 (completely) that described how much pain interfered with or affected a particular activity (max score= 10/question). A higher score suggests a higher impact by pain on a particular activity. A negative change from baseline is a positive outcome. There are 7 questions in total regarding Quality of Life. The average score of the 7 Quality of Life questions is reported (mean (SD)).

    Measured: Baseline, Weeks 2, 4, 8, 12

  4. Ocular Surface Parameters: Summary Statistics of Change From Baseline by Week - Conjunctival Redness - Nasal (Oculus Dexter (OD) = Right Eye)

    Conjunctival redness in each of two regions (nasal and temporal) was graded on a scale from 0 to 5 using the McMonnies conjunctival redness photographic scale (max score=5/region).
