Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
Exclusion criteria: 1.Any history of hypersensitivity to oxycodone, naloxone, or related products. 2.Subjects currently taking the equivalent of <10 mg or >40 mg/d oxycodone. (Refer to Appendix 12.2: Drug Conversion Tables.) 3.Subjects diagnosed with cancer, not including basal cell carcinoma. 4.Active alcohol or drug abuse. 5.Evidence of clinically significant cardiovascular, renal, hepatic, gastrointestinal (paralytic ileus), or psychiatric disease, as determined by medical history, clinical laboratory tests, ECG results, and physical examination, that would place the subject at risk upon exposure to the study medication or that may confound the analysis and/or interpretation of the study results. 6.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). 7.Surgery completed <= 2 months prior to the start of the Screening Period, planned surgery during the12-week Double-blind Phase, or any other pharmacological or non-pharmacological intervention that would influence pain during the study (not including chemotherapy) or preclude completion of the study. 8.Subjects presently taking, or who have taken, naloxone or an experimental drug <=30 days prior to the start of the Screening Period. 9.Subjects with a history of 2 or greater low back surgeries.

Primary Outcome(s)
|
Primary end point(s): Pain Event. A pain event is demonstrated by unacceptable pain control for 2 consecutive days. Each pain event is 2 discrete days, eg, there can be a maximum of 2 pain events in 4 days. A day of unacceptable pain control is defined as: 1) Pain Intensity Scale (“Average Pain over 24 Hours”) score = 5 or 2) Pain Intensity Scale (“Pain Right Now”) score = 5 accompanied by rescue medication of OXY IR at 1/4 the total daily oxycodone daily dose of OXY/OXN dosing = 2 times over one day. OR subjects may have a pain event by: 3) Study discontinuation due to lack of therapeutic effect.
|
Main Objective: To demonstrate the superiority of OXN over placebo on the time from the initial dose of study medication to multiple (ie, recurring) pain events (inadequate analgesia) during the Double-blind Phase.
|
Secondary Objective: •To determine sleep quality during treatment with OXN compared with placebo and OXY compared with placebo as measured by the sleep interference item of the Brief Pain Inventory Short Form (BPI-SF)5. •To determine the total amount of rescue medication used per day (24 hours) by subjects receiving OXN, OXY, and placebo. •To determine subjects’ global (12-week/early discontinuation) satisfaction with the study medication during the Double-blind Phase using the Patient Global Impression of Change scale (PGIC).
