You may not qualify if…

• Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
• Diagnosis of substance and/or alcohol dependence (excluding caffeine and nicotine).
• Has participated in, is currently participating in, or is seeking treatment for substance- and/or alcohol-related disorders (excluding nicotine and caffeine).
• Has a positive urine drug screen (UDS) excluding tetrahydrocannabinol (THC) at Screening and the admission for Qualification Phase.
• Has a positive alcohol breath test at Screening or upon admission to the study center for the Qualification Phase.
• Has any history of a condition in which an opioid is contraindicated
• History of sleep apnea in the past 5 years that has not been resolved.
• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject unsuitable for entry into this study.
• Positive test for Hepatitis B, Hepatitis C, or HIV at Screening.
• Allergy or history of hypersensitivity to naloxone hydrochloride (HCl), oxycodone HCl, other opioids, and/or lactose.
• Any condition possibly affecting drug absorption.
• Physical (eg, constricted or collapsed veins) or mental obstruction (ie, phobia) that would prevent serial blood sample collection.
• Clinically significant illness in the judgment of the investigator within 30 days before Screening.
• Treatment with an investigational drug within 30 days (or as determined by the local requirement, whichever is longer) or 5 half-lives preceding the first treatment during the Qualification Period (Visit 2), if longer than 30 days.
• Screening BP > 140 mm Hg (systolic) or > 90 mm Hg (diastolic) following at least 5 minutes of rest. If BP is > 140 mm Hg (systolic) or > 90 mm Hg (diastolic), the BP should be repeated two more times and the average of the three BP values should be used to determine the subject's eligibility.
• Pregnant females; breastfeeding females; males and females of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for 28 days after the last dose of study medication. Urine pregnancy tests must be collected and confirmed negative prior to dosing upon admission.
• Is currently taking a drug for a medical condition or a nutraceutical that poses a safety risk when administered with an opioid, cannot be safely withdrawn at Screening for the duration of the study, and/or will adversely affect the PD and safety assessments required by the study. Examples include antihypertensive agents, drugs for seizures, and diabetes medications. Hormonal contraceptives (oral, injected, intrauterine, transdermal or implanted) are allowed in this study provided the subject remains on the same treatment throughout the entire study and has been using that hormonal contraceptive for an adequate period of time to ensure effectiveness. Limited use of non-prescription medications that are not believed to affect subject safety or the overall results of the study may be permitted on a case-by-case basis following approval by the investigator. As an exception, acetaminophen may be used at doses of 1 g/day.
• Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 30 days prior to dosing.
• Unwilling or unable to comply with the procedures described in this protocol.
• Unwilling to be searched (including personal effects) for illicit substances before admission to the study center.
• Subject is a heavy smoker (> 20 cigarettes per day on average in the past 30 days prior to Screening), chews tobacco, uses nicotine-containing products (including nicotine transdermal patches), and/or is unable to abstain from smoking for at least 10 hours during any day.
• Current pending legal charges or currently on probation.
• Subjects who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or subjects who are PTI employees directly involved in the conduct of the study.
