Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects had to meet all the following criteria to be included in this study:
• Males and females at least 18 years of age (Females less than one year post-menopausal had to have a negative serum or urine pregnancy test recorded within 72 hours prior to the first dose of study medication, be non-lactating, and willing to use adequate and reliable contraception throughout the study.).
• Documented history of moderate to severe chronic pain of low back that required around-the-clock opioid therapy.
• Nonmalignant low back pain adequately managed by an opioid analgesic for at least the past 2 weeks.
• Subjects who required continuation of daily opioid analgesic treatment and were likely to benefit from chronic opioid therapy for the duration of the study.
• Subjects willing and able to participate in all aspects of the study, including use of oral medication, completion of subjective evaluations, attending scheduled clinic visits, completing telephone contacts, and compliance with protocol requirements as evidenced by providing written, informed consent.
• Bullet 3: Nonmalignant low back pain (for example osteoarthrosis / osteoarthritis of spine, deforming spondylosis, spondylolisthesis, disc herniation / sciatica, spinal stenosis) adequately managed by an opioid analgesic for at least the past 2 weeks.
• Bullet 4: Subjects who required continuation of daily opioid analgesic treatment and were likely to benefit from chronic opioid therapy (WHO step III opioid) for the duration of the study.

You may not qualify if:

• Subjects who met any of the following criteria were excluded from this study:
• Any history of hypersensitivity to oxycodone, naloxone, or related products.
• Subjects currently taking the equivalent of \< 10 mg or \> 40 mg/d oxycodone (Refer to Appendix 12.2 of the protocol: Drug Conversion Tables.).
• Subjects diagnosed with cancer, not including basal cell carcinoma.
• Active alcohol or drug abuse with severity sufficient to place the subjects at risk.
• Evidence of clinically significant cardiovascular, renal, hepatic, gastrointestinal (paralytic ileus), or psychiatric disease, as determined by medical history, clinical laboratory tests, Electrocardiogram (ECG) results, and physical examination, that would have placed the subject at risk upon exposure to the study medication or that could confound the analysis and/or interpretation of the study results.
• Abnormal aspartate aminotransferase (AST; SGOT), alanine aminotransferase (ALT; SGPT), or alkaline phosphatase levels (\> 3 times the upper limit of normal) or an abnormal total bilirubin and/or creatinine level(s) (outside of the reference range).
• Surgery completed less than 2 months prior to the start of the Screening Period, planned surgery during the 12-week Double-blind Phase, or any other pharmacological or non-pharmacological intervention that would have influenced pain during the study (not including chemotherapy) or precluded completion of the study.
• Subjects taking, or who had taken, naloxone or an experimental drug less than 30 days prior to the start of the Screening Period.
