Overview
Brief Summary
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 low back pain patients with a diagnosis of chronic low back pain.
Detailed Description
This 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 chronic low back pain who have moderate to severe, chronic low back pain that is not controlled by standard pain medications. JNJ-42160443 (10 mg/ml) or matching placebo given as a subcutaneous (SC) (under the skin) injection (inj) once every 4 weeks (wks); one of four JNJ-42160443 doses (1 mg every 4 wks; 3 mg every 4 wks; 6 mg loading dose on Day 1 followed by 3 mg every 4 wks; or 10 mg every 4 wks, or matching placebo for up to 104 wks (12-wk double-blind efficacy period + 92-wk double-blind extension period).
