This is an Open-label, Non-Randomized, 3-way Crossover Bioequivalence Study to compare fentanyl release after heating of a brand name (Duragesic) and generic (Apotex and Mylan) fentanyl skin patches in healthy adults.

Study summary:

This research study is intended to determine the effect of heat on FDA-approved fentanyl transdermal patches and whether the heat applied will result in more fentanyl being absorbed through the skin than without applying heat. This is important given that little is known about how the release of fentanyl is affected by heat, particularly for generic products that are also available over the counter. This study will use fentanyl patches (brand name and generic patches) that have been approved by the Food and Drug Administration (FDA) and are already sold over the counter to customers in the United States, and will not include any placebos.


Inclusion Criteria: - 1. Men or non-pregnant women of any ethnic background between the age of 18 and 45 years old. - 2.

Subjects deemed to be healthy as judged by the Medically Accountable Investigator (MAI) and determined by medical history, physical examination, and medication history. - 10. Negative urine drug screening test. - 11. Have a normal blood pressure (systolic: 90-140 mmHg; diastolic: 50-90 mmHg) and heart rate (55-100 bpm). - 12.

Agrees not to participate in another clinical study during the study period. - 16. Agrees not to donate blood to a blood bank throughout participation in the study and for at least 3 months after last procedure day. - 17. Have a normal ECG. Exclusion Criteria: - 1. Women who are pregnant, lactating breast feeding or have a positive serum pregnancy test at enrollment or on the morning of any procedure day. - 2. Smokers (current use or use over the previous 2 months of nicotine-containing substances, including tobacco products (e.g., cigarettes, cigars, chewing tobacco, gum, patch or electronic cigarettes). - 3. Participation in any ongoing investigational drug trial or clinical drug trial. - 4. Abnormal Vital signs, defined as: - Hypertension (systolic blood pressure >140 mm Hg or diastolic blood pressure >90 mm Hg) at rest on 2 separate days) - Heart rate <55 at rest on 2 separate days - Respiratory rate >20 - 5. Temperature > 38.0°C (100.4°F) or symptoms of an acute self-limited illness such as an upper respiratory infection or gastroenteritis within 7 days of application of the transdermal fentanyl patch. - 6. History of chronic obstructive pulmonary disease. - 7. Active positive Hepatitis B, C, and HIV serologies. - 8. Positive urine drug screening test. - 9. Use of any prescription medication during the period 0 to 30 days or over-the counter medication (vitamin, herbal supplements and birth control medications not included) during the period 0 to 3 days before entry to the study. - 10. Donation or loss of greater than one pint of blood within 60 days of entry to the study. - 11. Any prior serious adverse reaction or hypersensitivity to fentanyl, naltrexone or naloxone or any of the inactive ingredients in the patch (alcohol, ethylene vinyl acetate-copolymer membrane and hydroxyethyl cellulose, polyester, silicone adhesive, isopropyl myristate, octyldodecanol, polybutene, polyisobutene, dimethicone NF, or polyolefin). - 12. Have a diagnosis of schizophrenia or other major psychiatric diagnosis or mental illness (e.g. major depression). - 13. Received an experimental agent (vaccine, drug, biologic, device, blood product or medication) within 1 month before enrollment in this study or expects to receive an experimental agent during the study. - 14. Any condition that would, in the opinion of the Medically Accountable Investigator (MAI), place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol. - 15. Inability to communicate or co-operate with the investigators. - 16. History of consumption of alcohol within 24 hours prior to dose administration. - 17. Within 72 hours prior to dosing, use of antihistamines or use of topical drugs at patch site. - 18. Subject has an obvious difference in skin color between arms or the presence of a skin condition, open sore, scar tissue, tattoo, or coloration that would interfere with placement of test articles, skin assessment, or reactions to drug. - 19. Use of monoamine oxidase inhibitors 21 days prior to study. - 20. Failure to pass opioid dependence challenge test on each procedure day before application of the fentanyl patch. Each subject will be injected subcutaneously with naloxone HCl (0.8 mg injection) and will be observed for 45 minutes for signs and symptoms of opioid withdrawal.
