Brief summary: The purpose of this study is to assess the bioequivalence of a new oxycodone formulation (40 mg) relative to the original OxyContin® (OXY) formulation (40 mg) in the fasted state.

Detailed description: Oxycodone hydrochloride (oxycodone) is a semi-synthetic opioid analgesic that is effective in the relief of moderate to severe malignant and non-malignant pain.

* Females of child-bearing potential must be using an adequate and reliable method of contraception.

Exclusion Criteria:

* Females who are pregnant or lactating.
* Any history of or current drug or alcohol abuse for 5 years.
* History of or any current conditions that might interfere with drug absorption, distribution, metabolism or excretion.
* Use of an opioid-containing medication in the past 30 days.
* History of known sensitivity to oxycodone, naltrexone, or related compounds.

* History of smoking or use of nicotine products within 45 days of study drug administration or a positive urine cotinine test.
* Blood or blood products donated within 30 days prior to administration of the study drugs or anytime during the study, except as required by this protocol.
* Positive results for urine drug screen or alcohol screen at Check-in of each period, and HBsAg, HBsAb (unless immunized), anti-HCV.
* Positive Naloxone HCl challenge test.
* Presence of Gilbert's Syndrome or any known hepatobiliary abnormalities.
