Brief Summary

The purpose of this study is to determine whether intra-articular (knee joint) administration of MEN16132 is effective reducing the pain from knee osteoarthritis.

Detailed Description

MEN16132 is a non-peptide bradykinin B2-receptor antagonist showing analgesic and anti-inflammatory activity in nonclinical osteoarthritis models. This study is being conducted as a dose finding study to determine the safety and efficacy of MEN16132, given as three doses/four treatment regimens in comparison to placebo, as well the time to onset and duration of effect.

  • Use of systemic or topical corticosteroids >10 mg prednisolone equivalent per day during 30 days prior to randomisation.
  • Use of any pain or OA medication (e.g. NSAIDs, COX-2 inhibitors, analgesics) during 1 or 2 weeks prior to randomisation.
  • Any intra-articular or local periarticular punction, injection or surgery to the index knee during the 6 months prior to screening.

Primary Outcome Measures
NameTimeMethod
WOMAC VA 3.1 A Score (Total Pain)over the 3 weeks after the first administration

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.

Secondary Outcome Measures
NameTimeMethod
WOMAC VA 3.1.B Score (Knee Stiffness)up to 3 months after first dose

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.

WOMAC VA 3.1. C Score (Function)up to 3 months after first dose

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.

Percentage of Treatment Responders According to OMERACT-OARSI Responder Criteriaup to 3 months after first dose

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 Assessmentup to 3 months after first dose

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.

WOMAC VA 3.1A - Total Pain Score by Body Mass Index [BMI <= 25]over the 3 weeks after the first administration

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.

WOMAC VA 3.1A - Total Pain Score by Body Mass Index -[BMI > 25]over the 3 weeks after the first administration

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.

Adverse Event Reportsup to 4 months after screening

Incidence of spontaneously reported adverse events

Clinically Significant Abnormal Laboratory Testsup to 4 months from screening
