A Study to Characterize the Abuse Liability of ALO-02 in Healthy, Non-Dependent, Recreational Opioid Users When ALO-02 Capsules Are Crushed and Snorted

17. april 2017 opdateret af: Pfizer

A Randomized, Double-blind, Placebo Controlled, Single-dose, 4-way Crossover Study To Determine The Relative Abuse Potential Of Alo-02 (Oxycodone Hydrochloride And Naltrexone Hydrochloride Extended Release Capsules) Compared To Oxycodone Immediate Release, And Placebo When Administered Intranasally To Non-dependent, Recreational Opioid Users.

The main purpose of this study is to determine if oxycodone and naltrexone combination capsules (ALO-02) have the potential to be abused when they are crushed and snorted.

Drug liking assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment). It is scored using a 100 millimeter (mm) bipolar VAS anchored in the center with a neutral anchor of "neither like nor dislike" (score of 50 mm), on the extreme left with "strong disliking" (score of 0 mm) and on the extreme right with "strong liking" (score of 100 mm). Peak Effect (Emax) = Maximum observed score.

Drug liking assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment). It is scored using a 100 mm bipolar VAS anchored in the center with a neutral anchor of "neither like nor dislike" (score of 50 mm), on the left with "strong disliking" (score of 0 mm) and on the right with "strong liking" (score of 100 mm). AUE (0-x) = Area under the effect versus time curve from time 0 to x hours (0-x).

Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)
Tidsramme: Screening up to 3 to 7 days following last study drug administration, or time of early withdrawal
An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. SAE: an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 3 - 7 days following last study drug administration that were absent before treatment or that worsened relative to pre-treatment state. Symptoms of withdrawal following naloxone administration (naloxone challenge phase) were not collected as adverse events unless they met the criteria for an SAE. AEs included SAEs as well as non-serious AEs which occurred during the trial.

Tidsramme: Drug discrimination phase: pre-dose up to 5 hours; intervention period: pre-dose up to 12 hours
Oxygen saturation of hemoglobin in blood (SpO2) was monitored using pulse oximetry continuously for 5 hours following dosing in the drug discrimination phase and continuously for 12 hours following dosing in the treatment phase, or longer at the discretion of the investigator. Individual measurement was collected in a sitting position. If SpO2 fall below 90 percent (%), the investigator administered oxygen via nasal cannula at a flow rate sufficient to maintain the SpO2 greater than or equal to 90%. Participants with fall in SpO2 below 90% were reported.
Drug discrimination phase: pre-dose up to 5 hours; intervention period: pre-dose up to 12 hours
