Participant Flow

The study was conducted at 10 study centers in Canada. A total of 210 patients with OA of the knee were randomly assigned to double-blinded treatment in the study; of these, 105 patients received G001 and 105 patients received Vehicle.

Following screening, prior NSAID and/or acetaminophen use was discontinued to allow for washout (3 to 7 days) and symptom flare. Eligible patients with adequate OA pain in the index knee were randomly assigned to G001 or Vehicle in a 1:1 allocation ratio.

PGA of Disease Activity (DA) was assessed on a 5-point Likert scale (0 = very good; 1 = good; 2 = fair; 3 = poor; and 4 = very poor), with higher scores indicating worse outcome. Change from Baseline in PGA of disease activity scores was calculated and the response was classified into 3 categories according to the following rules: Improved - defined as either of the following: * For baseline Grade ≥ 2: a reduction of ≥ 2 grades from baseline * For baseline Grade = 1: a change in grade from 1 to 0 Worsened - defined as either of the following: * For baseline Grade ≤ 2: an increase of ≥ 2 grades from baseline * For baseline Grade = 3: a change in grade from 3 to 4 No Change - defined as neither Improved nor Worsened

The Numerical Total Score is the sum of the Dermal Response score (from 0=No evidence of irritation to 7=Strong reaction spreading beyond the application site) and the numeric equivalent of Other Effects score (from 0=Slightly glazed appearance to 3=Small petechial erosions and/or scabs). The Numerical Total Score range is from 0 to 10, with higher scores indicating worse outcome/skin irritation.

0/105 • Adverse event (AE) collection period: from the Screening Visit (Day -7 to -3) to the Week 6/End-of-Study (EOS) Visit (Day 43 +/-3). Analyses of AEs were performed for treatment-emergent events (TEAEs), defined as any AE with onset during or after the first application of study drug through the end of the study (Week 6/EOS visit), or any event that was present at Baseline but worsened in severity during or after the first application of study drug.
Adverse events of special interest for G001 included application site adverse reactions. All AEs occurring between the Screening visit and the Week 6/EOS visit were recorded in the patient's medical record and eCRF.
