About this study

The purpose of this study is to compare the presence, degree, time course and profile of opioid withdrawal symptoms associated with induction onto new formulations of buprenorphine or buprenorphine/naloxone in persons with active opioid dependence. The primary outcome measure is the severity of withdrawal symptoms measured using the Clinical Opiate Withdrawal Scale (COWS). The primary study hypothesis is that neither drug formulation will precipitate an opioid withdrawal syndrome.

Read the detailed description

Buprenorphine sublingual and buccal soluble films are being developed to be used for the same indication and over the same buprenorphine dose range as Subutex and Suboxone sublingual tablets in the treatment of opioid dependence. However, only films administered by the sublingual route were evaluated in this study.

The soluble film dosage is expected to provide the following enhancements and potential advantages over the current Subutex and Suboxone product:

  • Mitigation against unintentional pediatric exposure by providing child-resistant packaging in unit dose format.
  • Improvement in subject convenience and compliance by ensuring rapid disintegration.
  • Protection against diversion by providing a dosage form that is very difficult for the subject to remove from the sublingual or buccal mucosa after administration. This provides assurance to the caregiver that the dose has actually been taken appropriately in a supervised setting.
  • Provision of a unit dose product format for hospital and institutional use.
  • Decreased product damage during shipping as compared to Subutex and Suboxone tablets.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Severity of Withdrawal Symptoms Measured Using the Clinical Opiate Withdrawal Scale (COWS) at Baseline and the Peak COWS up to 23.5 Hours After the First Administration

    The COWS is an 11-item instrument used to assess symptoms of opioid withdrawal (Wesson et al., 1999). The score is the sum of the response to each of the 11 items and cover a range of 0-48. The COWS is commonly used by clinicians treating patients with buprenorphine to monitor the severity of withdrawal. COWS scores below 5 are considered not indicative of withdrawal. Scores from 5 to 12 are considered mild withdrawal; from 13 to 24 moderate withdrawal; 25 to 36 moderate/severe withdrawal, and 37-48 severe withdrawal.

    The baseline COWS was the score obtained 30 minutes prior to administration of soluble films on Day 1. Peak COWS was the highest COWS score obtained between 1-23.5 hours post administration on Day 1.

    Measured: Baseline: 30 minutes prior to first administration on Day 1. Peak: up to 23.5 hours post administration on Day 1

Secondary outcomes (17)
  1. Severity of Withdrawal Symptoms Measured Using the Clinical Opiate Withdrawal Scale (COWS) at the End of Induction and the Peak COWS Post Induction

    The COWS is an 11-item instrument used to assess symptoms of opioid withdrawal (Wesson et al., 1999). The score is the sum of the response to each of the 11 items and cover a range of 0-48. The COWS is commonly used by clinicians treating patients with buprenorphine to monitor the severity of withdrawal. COWS scores below 5 are considered not indicative of withdrawal. Scores from 5 to 12 are considered mild withdrawal; from 13 to 24 moderate withdrawal; 25 to 36 moderate/severe withdrawal, and 37-48 severe withdrawal.

    The end of induction COWS was the score obtained 47.5 hours after first administration of soluble films on Day 1. Peak post induction COWS was the highest COWS score obtained on Days 2-5.

  4. Pupil Diameter Measurements At End of Induction (End of Day 2) and the Minimum Pupil Diameter During the Post Induction Period (Days 3-5)

    Pupil diameter was measured at the end of induction (47.5 hours after the first administration of study intervention) and at intervals during the post-induction period (Days 3-5). Peak post induction measurement is the minimum pupil diameter recorded during days 3-5.

    Measured: End of Induction: 47.5 hours after first administration Peak Post Induction: Days 3-5

  5. Visual Analog Scale (VAS) Score at Baseline and the Peak (Maximum Increase) VAS up to 23.5 Hours After First Administration for the Question: "How High Are You?"

The question was one of six used to measure the extent of opioid blockade following study intervention. VAS questions were selected based on previous demonstration of their sensitivity to opioid agonist and antagonist effects (Preston et al., 1988). Participants indicated how high they feel by marking a score on a horizontal line with 0=not high and 100=extremely high.

    The baseline VAS was the score obtained 30 minutes prior to administration of soluble films on Day 1. Peak VAS was the highest VAS score obtained between 1-23.5 hours post administration on Day 1.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Buprenorphine soluble film and Buprenorphine/naloxone film strip in people with Opioid-related Disorders, run by Indivior Inc. at 1 site in United States.

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 5 inclusion and 13 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 5 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 May 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Severity of Withdrawal Symptoms Measured Using the Clinical Opiate Withdrawal Scale (COWS) at Baseline and the Peak COWS up to 23.5 Hours After the First Administration (time frame: Baseline: 30 minutes prior to first administration on Day 1. Peak: up to 23.5 hours post administration on Day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Jun 2017.
