To Determine the Safety, Tolerability, Pharmacokinetics and Effect on Pain of a Single Intra-articular Administration of Canakinumab in Patients With Osteoarthritis in the Knee

Novartis Pharmaceuticals169 enrolled

Overview

The purpose of this study was to determine whether, in patients with mild to moderate knee osteoarthritis, canakinumab is safe and tolerable when injected intra-articularly.

This is a randomized, double-blind, parallel group, placebo controlled 18 weeks study, consisting of two parts: 1. Part A: an ascending single dose part in which the safety and tolerability of up to 4 different canakinumab doses are studied (starting dose 150 mg, maximum dose 600 mg). 2. Part B: a double-dummy, active-controlled, parallel design part in which the pain reduction of the canakinumab dose selected from part A is studied in comparison to Placebo and Naproxen.

Outcomes

Primary Outcomes

Part A: Number of Participants With Intolerance Events

An intolerance event is defined as an acute inflammatory reaction, characterized by a 30 mm increase in pain (on a 100 mm visual analog scale (VAS) and associated with a new or worsened synovial fluid effusion within 3 days following the intra-articular (i.a.) injection. If baseline VAS pain score is ≥ 70 mm, an intolerance event is defined as an increase in pain by 20 mm on a 100 mm VAS associated with new or worsened synovial fluid effusion within 3 days following the i.a. injection. If baseline VAS pain score is ≥ 80 mm, an intolerance event is defined as an increase in pain by 10 mm on a 100 mm VAS associated with new or worsened synovial fluid effusion within 3 days following the i.a. injection. If baseline pain score is ≥ 90 mm, an intolerance event is defined as the patients experiencing an unspecified increase in pain on a 100 mm VAS associated with new or worsened synovial fluid effusion within 3 days following the i.a. injection.

Time frame: Baseline to Day 3

Part B: Change From Baseline to Day 4 in Pain Using 100 mm Visual Analog Scale (VAS)

After walking for 20 meters, participants were asked to assess the pain in their affected knee on a 100 mm linear visual analog scale ranging from no pain (0 mm) to unbearable pain (100 mm). A negative change from Baseline score indicates improvement. Results are from a Bayesian analysis of covariance (ANCOVA) model, fitting baseline pain VAS score as a covariate, time by treatment as fixed effects, region and subject as random effects.

Time frame: Baseline and Day 4

Part B: Change From Baseline to Week 4 in Western Ontario and McMaster Osteoarthritis Index (WOMAC) Pain Subscale

The Western Ontario and McMaster osteoarthritis Index (WOMAC) pain subscale asks patients to rate pain in the index knee joint in the last 48 hours doing different activities on a scale from none (0) to extreme pain (4). The answers are summed and the total pain subscale score ranges from 0 to 20, where higher scores indicate more pain. A negative change from Baseline score indicates improvement. Results are from a Bayesian ANCOVA model, fitting baseline WOMAC pain score as a covariate, time by treatment as fixed effects, region and patient as random effects.

Time frame: Baseline and Week 4

Secondary Outcomes

Part B: Change From Baseline in Pain Using 100 mm Visual Analog Scale (VAS)

After walking for 20 meters, participants were asked to assess the pain in their affected knee on a 100 mm linear visual analog scale ranging from no pain (0 mm) to unbearable pain (100 mm). Results are from a Bayesian ANCOVA model, fitting baseline pain VAS score as a covariate, time by treatment as fixed effects, region and patient as random effects.

Time frame: Baseline and Weeks 4, 8 and 12

Part B: Percentage of Responders in the Pain 100 mm Visual Analog Scale (VAS)

A responder is defined as a participant with a 50% or greater reduction from baseline on the VAS scale for pain assessment. After walking for 20 meters, participants were asked to assess the pain in their affected knee on a 100 mm linear visual analog scale ranging from no pain (0 mm) to unbearable pain (100 mm).

Time frame: Baseline, Day 4, Weeks 1, 2, 4, 8 and 12

Part B: Change From Baseline in WOMAC Pain, Stiffness and Physical Function Subscales

The WOMAC consists of 3 subscales: The Pain subscale asks patients to rate pain in the index knee joint in the last 48 hours during walking, using stairs, in bed, sitting or lying, and standing on a scale from none (0) to extreme pain (4). The answers are summed and the total pain subscale score ranges from 0-20. The Stiffness subscale assesses stiffness in the index knee joint during the last 48 hours doing different activities on a scale from none (0) to extreme stiffness (4). The total stiffness subscale score ranges from 0-8. The Physical Function subscale assesses difficulty performing daily physical activities during the last 48 hours on a scale from none (0) to extreme difficulty (4). The total physical function subscale score ranges from 0-68. Higher scores indicate more pain/stiffness/difficulty. Results are from a Bayesian ANCOVA model, with baseline WOMAC score as a covariate, time by treatment as fixed effects, region and patient as random effects.

Time frame: Baseline and Weeks 4, 8 and 12

Part B: Proportion of Participants Who Used Rescue Analgesic During Study

Participants were permitted to take oral rescue medication (Acetaminophen ≤ 4 gram/day) up until 24 hours of a scheduled assessment visit during the 12-week treatment period. The estimates shown are the Kaplan-Meier estimates of the proportion of participants that took rescue medication.
