Trial Outcomes & Findings for A Locally Injected Bradykinin Antagonist for TReatment of OSteoarthritiS (NCT NCT01091116)

Outpatients were recruited from March 2010 to November 2010 in private practice and hospitals.

A Locally Injected Bradykinin Antagonist for TReatment of OSteoarthritiS

Western Ontario and McMaster Universities osteoarthritis index (WOMAC). The WOMAC VA 3.1 A score (total pain , range 0-500 mm) is the sum of VAS scores (0-100 mm) attributed by the patient to each of the 5 questions referring to osteoarthritic pain experienced during the preceding 48 hours. The higher is the WOMAC VA 3.1 A score, the higher is the intensity of pain symptoms (0 = no pain ; 500 = extreme pain). A decrease of the WOMAC VA 3.1 A score following treatment administration indicates a reduction of pain symptom. The change from baseline was assessed along 3 weeks after first drug administrations.

WOMAC VA 3.1.B score(range 0-200) is the sum of VAS scores (0-100 mm)attributed by the patient to each of the 2 questions referring to joint stiffness experienced during the preceding 48 hours. The higher is the WOMAC VA 3.1 B score, the higher is joint stiffness (0 = no stiffness ; 200 = extreme stiffness). A decrease of the WOMAC VA 3.1 B score following treatment administration indicates a reduction of joint stiffness. The change at Week 13 from baseline is reported.

Knee function evaluated by WOMAC VA 3.1 C score (range 0-1700) is the sum of VAS scores (range 0-100 mm) attributed by the patient to each of 17 questions referring to difficulty in performing daily activities experienced during the preceding 48 hours. The higher is the WOMAC VA 3.1 C score, the higher is functional impairment in daily activities (0 = no difficulty ; 1700 = extreme difficulty). A decrease of the WOMAC VA 3.1 C score following treatment administration indicates an improvement in performing daily activities. WOMAC VA 3.1.C scores at baseline and at Week 13 are reported.

Osteoarthritis Research Society International (OARSI). Response defined as: * a decrease in WOMAC pain or physical-function score by 50% or more and by 20 or more points on the visual analogue scale * OR if two of the following three findings are recorded: a decrease in the WOMAC pain score by 20% or more and by 10 or more points on the visual analogue scale; a decrease in the WOMAC physical-function score by 20% or more and by 10 or more points on the scale; an improvement in the score on the patient's global assessment by 20% or more and by 10 or more points on the scale.

Patient global assessment evaluated using a VAS scale score attributed by the patient (range 0-100 mm). Efficacy assessed as change at each time-point post-dosing (week 1, 2 ,3, 13) versus baseline (week 0). A decrease of patient global assessment score indicates an improvement of osteoarthritis symptoms.

Analysis in normal-weight population (BMI \<= 25) of the WOMAC VA 3.1A score (range 0-500 mm) is reported. A decrease of the WOMAC VA 3.1 A score following treatment administration indicates a reduction of pain symptom.

Analysis in over-weight population (BMI \> 25) of the WOMAC VA 3.1A score (range 0-500 mm) is reported. A decrease of the WOMAC VA 3.1 A score following treatment administration indicates a reduction of pain symptom.
