Transdermal Patch CVD 2000: The Effect of Heat on Fentanyl Release From Fentanyl TDSs in Healthy Adults

Study Overview
=================
Brief Summary
-----------------
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 (transdermal delivery system)TDSs in healthy adults.

Detailed Description
-----------------
This research study is intended to determine the effect of heat on FDA-approved fentanyl TDSs 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. This study will use fentanyl TDSs (brand name and generic TDSs) that have been approved by the Food and Drug Administration (FDA) and are already prescribed to customers in the United States, and will not include any placebos.

Able to adhere to the study protocol schedule. 7. Subjects who are within their ideal body weight (BMI>17 and ≤ 28). 8. Demonstrate comprehension of the protocol procedures and knowledge of study by passing (>70% correct responses) a written examination containing 20 multiple choice and true false questions covering all aspects of the study including the purpose, procedures, risks and benefits. 9. 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. Have normal screening laboratories for WBC, Hgb, platelets, sodium, potassium, chloride, bicarbonate, BUN, creatinine, ALT, AST and total bilirubin. 13. Have normal screening laboratories for urine protein and urine glucose. 14. Female subjects must be of non-childbearing potential (as defined as surgically sterile [i.e. history of hysterectomy or tubal ligation] or postmenopausal for more than 1 year), or if of childbearing potential must be non-pregnant at the time of enrollment and on the morning of each procedure, and must agree to use hormonal or barrier birth control such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence, or a vasectomized partner. 15. 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 fentanyl TDS. 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 TDS (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 TDS 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 TDS. 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.
