Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* The back pain must be related to nonmalignant and nonneuropathic conditions and without radiation or with only proximal radiation (above the knee);
* Subjects must be on opioid analgesic therapy for low back pain which:
* Has been ongoing for at least 4 weeks prior to the screening visit and,
* Consists of a stable opioid regimen at a total average daily dose equivalent to 20 to 160 mg (inclusive) of morphine for the last 2 weeks prior to the screening visit. Subjects taking tramadol ≥ 100 mg daily on a stable regimen for the last 2 weeks prior to the screening visit will also meet this criterion;
* Subjects must require continuation of opioid analgesic treatment in the range of 40 to 160 mg (inclusive) of morphine or its equivalent daily and be likely to benefit from chronic around-the-clock opioid therapy for the duration of the study;
* Subjects must have an average pain over the last 14 days score ≥ 5 (on an 11-point numerical rating scale \[NRS\]) at the screening visit, on their current opioid analgesic medication and, if applicable, nonopioid medication;
* Subjects must have an average pain over the last 24 hours score ≥ 5 (on an 11-point NRS) at the screening visit, on their current opioid analgesic medication and, if applicable, nonopioid medication;
* Subjects must be willing and able to be compliant with the protocol, capable of subjective evaluation, able to read and understand questionnaires, willing and able to use a diary per protocol, and read, understand, and sign the written informed consent in English.
Exclusion Criteria
* Subjects with any contraindication or any history of hypersensitivity to oxycodone, naloxone, or other opioids. This does not include subjects who have experienced common opioid side effects (e.g., nausea, constipation);
* Subjects with acute spinal cord compression, acute compression fracture, seronegative spondyloarthropathy, acute nerve root compression, cauda equina compression, fibromyalgia, reflex sympathetic dystrophy or causalgia (complex regional pain syndrome), diabetic amyotrophy, meningitis, discitis, or back pain due to secondary infection, tumor, or postherpetic neuralgia;
* Subjects with gout, unless controlled on stable suppressive treatment with colchicine or uric-acid-lowering therapy without any attacks for ≥ 2 years and the subject has not been using nonsteroidal anti-inflammatory drugs (NSAIDs) or COX-2 inhibitors on a regular basis;
* Subjects with pseudogout, psoriatic arthritis, active Lyme disease, rheumatoid arthritis or other inflammatory arthritis, or neuropathic pain conditions;
* Subjects who had surgical procedures directed towards the source of chronic low back pain within 6 months of the screening visit or planned during the study;
* Subjects with a history of opioid, alcohol, medication, or illicit drug abuse or addiction;
* Subjects who have received any investigational medication within 30 days of first dose of study drug;
* Subjects currently taking, or who have taken naloxone, naltrexone, methylnaltrexone, or alvimopan within 10 days before the screening visit;
* Subjects who have received study drug in a clinical study of oxycodone/naloxone controlled-release (OXN or ONU).
