A Randomized, Double-Blind, Placebo-Controlled, Dose-Ranging Study to Evaluate the Efficacy, Safety, and Tolerability of JNJ-42160443 as Adjunctive Therapy in Subjects With Moderate to Severe Knee or Hip Pain From Osteoarthritis
A Randomized, Double-Blind, Placebo-Controlled, Dose-Ranging Study to Evaluate the Efficacy, Safety, and Tolerability of JNJ-42160443 as Adjunctive Therapy in Subjects With Moderate to Severe Knee or Hip Pain From Osteoarthritis
The purpose of this study is to compare the safety and effectiveness of different doses of JNJ-42160443 with placebo in the treatment of chronic, moderate to severe knee or hip pain in patients with a diagnosis of osteoarthritis.
This current study is a randomized (study drug assigned by chance), double-blind (neither the physician nor the patient knows the name of the assigned drug) study to evaluate the safety and effectiveness of different doses of JNJ-42160443 compared with placebo in the treatment of patients with a diagnosis of osteoarthritis of the hip or the knee who have moderate to severe pain that is not controlled by standard pain medications.Osteoarthritis is a chronic disease that affects the joints, and is characterized by degeneration of cartilage and bone. The duration of the study is approximately 133 weeks (3-week screening phase, 12-week double-blind efficacy phase, 92-week double-blind extension phase, and 26-week post treatment phase).JNJ-42160443 (10 mg/mL) or matching placebo given as an subcutaneous (injection under the skin) (SC) once every 4 weeks will be administered in the study as 1 of 5 JNJ-42160443 dosages:1 mg every 4 weeks, 3 mg every 4 weeks, 3 mg every 8 weeks, 6 mg every 8 weeks; or 10 mg every 8 weeks, or matching placebo for up to approximately 104 weeks (12-week double-blind efficacy phase + 92-week double-blind extension phase).
Inclusion Criteria:
Diagnosis of osteoarthritis of the hip or the knee; Have an average daily pain intensity score of >=5 averaged over the last 3 days before treatment assignment; Receiving a stable dose of non-steroidal anti-inflammatory drugs for a minimum of 5 days each week for the 4 weeks before screening or a stable dose of immediate-release opioids for a minimum of 5 days each week for the 4 weeks before screening, but not exceeding 200 mg oral morphine equivalents per day or a stable dose of long acting opioids for the 4 weeks before screening; but not exceeding 200 mg oral morphine equivalents per day; Have a mini mental state examination score of >=26 at screening.
