简要总结
The purpose of this study is to assess the relative abuse potential of the hydrocodone bitartrate extended-release tablet compared to immediate-release hydrocodone bitartrate.
详细描述
Hydrocodone bitartrate is a semisynthetic opioid analgesic and antitussive. Hydrocodone is widely used for various indications similar to those of codeine, primarily for relief of moderate to moderately severe pain. For the treatment of pain in the United States, hydrocodone is currently available only as an immediate-release (IR) product in combination with other medications such as acetaminophen or ibuprofen. The extended-release (ER) formulation tested in this study is designed to be resistant to dose dumping with alcohol or rapid release of hydrocodone after tampering.
The study will consist of 3 phases: A, B,and C. Phase A is the screening phase where subject eligibility will be confirmed (Visit 1). Subjects who are eligible will enter Phase B, a double-blind, 2-period crossover design (Visit 2) followed by Phase C, a double-blind 4-period crossover design (Visits 3 through 6).
Phase B is the randomized, double-blind, placebo-controlled, 2-treatment, 2- period crossover portion of the study which is designed to ensure that the subject can tolerate a 45-mg dose of hydrocodone and that the subject can discriminate between the effect of hydrocodone and the effect of placebo. Subjects will arrive at the study center on the day prior to the first study drug administration and remain at the study center for a minimum of 24 hours after the second study drug administration in phase B. After a review of the inclusion/exclusion criteria and check-in procedures (including a Naloxone Challenge),eligible subjects will be randomly assigned to one of 2 treatment sequences. For subjects who qualify to continue into phase C, there will be a minimum 7-day washout period between the second dose in phase B and the first dose in phase C.
Phase C is the randomized, double-blind, triple-dummy, placebo-controlled, 4-period crossover portion of the study. Subjects will arrive at the study center the day prior to each study drug administration in phase C and remain at the study center through 72 hours after study drug administration in each period. Eligible subjects will be randomly assigned to 1 of 4 treatment groups. Each dose in phase C will be separated by a minimum 14 day washout period.
All subjects (including those who withdraw from the study) will be asked to return to the study center for a follow-up visit approximately 48 to 72 hours after discharge from the study center following their final dose of study drug.

主要结局
Drug Liking and Effects Questionnaire (DLEQ)
时间窗: Phase B: prior to and at designated times up to 24 hours after study drug administration. Phase C:prior to and at set times up to 72 hours after study drug administration
The DLEQ measures positive, negative, and any drug effects using bipolar and unipolar VAS. Bipolar VAS range from a strong negative response (score of 0) to a strong positive response (score of 100) with a neutral midpoint (score of 50). Unipolar VAS range from a response of 'none' (score of 0) to 'extremely' (score of 100). Questions include assessments of liking, drowsiness, good effects, bad effects, nausea,and any effects. The primary outcome is question 1 which states: "My liking for this drug is:"
