Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy male or female subjects 18 to 55 years of age, inclusive.
  • Subject is a recreational opioid user who is NOT dependent on opioids based on Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision (DSM-IV-TR) criteria and the Naloxone Challenge. A recreational opioid user is defined as use of opioids for non-therapeutic purposes (i.e., for psychoactive effects) on at least 10 occasions within the last year and at least once in the 12 weeks before the Screening Visit (Visit 1).
  • Subjects must have experience with intranasal drug administration, defined as intranasal use on at least 3 occasions within the last year prior to the Screening Visit.

Who cannot join

  • Diagnosis of substance and/or alcohol dependence (excluding caffeine and nicotine), as assessed by the Investigator using the DSM IV-TR criteria.
  • Has participated in, is currently participating in, or is seeking treatment for substance- and or alcohol-related disorders (excluding nicotine and caffeine).
  • Has any condition in which an opioid is contraindicated; e.g., significant respiratory depression, acute or severe bronchial asthma or hypercarbia, or is suspected of having paralytic ileus.
  • Allergy or history of hypersensitivity to morphine sulfate, other opioids, naltrexone hydrochloride, naloxone, and/or lactose.
  • History or current clinically significant neurological, cardiovascular, renal, hepatic, endocrine, gastrointestinal, hematologic, or metabolic disease as evaluated by the Investigator.
  • History or current pulmonary disease including asthma, chronic obstructive pulmonary disease, exercise-induced asthma, bronchitis, and obstructive sleep apnea.

About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, 3 Way Crossover Study Evaluating The Relative Abuse Potential Of Crushed Embeda Compared To Morphine Sulfate Controlled Release Tablets (Crushed) And Placebo In Non-Dependent, Recreational Opioid Users Following Intranasal Administration

This was a single-dose, randomized, double-blind, placebo-controlled, 3 way crossover study designed to evaluate the relative abuse potential of crushed EMBEDA® compared to morphine sulfate CR tablets and placebo in healthy male and female, non-dependent, recreational opioid users. An appropriate dose of morphine sulfate CR (i.e., 30 mg, 60 or 90 mg) was to be selected during Part A of the study (Dose Selection Phase). Each subject participated in the study for up to (approximately) 16 weeks and was confined in the clinic for a total of up to 12 nights.

Being tested
Placebo, EMBEDA - morphine sulfate/ naltrexone hydrochloride, morphine sulfate CR crushed.
Keywords

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EMBEDA - morphine sulfate/ naltrexone hydrochloride and morphine sulfate CR crushed. in people with Narcotic Abuse and Opioid-related Disorders, run by Pfizer.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Drug Liking Visual Analog Scale maximum peak effect (Emax) (time frame: 0.5, 1, 1.5, 2, 3, 4, 6, 8,12, and 24 hours post-dose). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01595867, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2012.
