Brief summary: The purpose of this study is to assess the bioequivalence of a new oxycodone formulation (80 mg) relative to the original OxyContin® (OXY) formulation (80 mg) in the fed 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.

* Healthy and free of significant abnormal findings as determined by medical history, physical examination, vital signs, and electrocardiogram (ECG).
* Females of child-bearing potential must be using an adequate and reliable method of contraception.
* Willing to eat all the food supplied during the study.

Exclusion Criteria:

* Females who are pregnant or lactating.
* Any history of or current drug or alcohol abuse for 5 years.

* Use of an opioid-containing medication in the past 30 days.
* History of known sensitivity to oxycodone, naltrexone, or related compounds.
* Any history of frequent nausea or emesis regardless of etiology.
* Any history of seizures or head trauma with current sequelae.

* 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 hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb) (unless immunized), hepatitis C antibody (anti-HCV).
* Positive Naloxone hydrochloride (HCl) challenge test.
