About this study

Official title: A Randomized, Double-blind, Double-dummy, Active-drug-controlled, Parallel-group, Multicentre Acceptability and Safety Study of the Transfer From Subutex/Suboxone to RBP-6300 in Opioid-dependent Subjects

This study is designed to determine if opioid dependent subjects who are already receiving Subutex and/or Suboxone can transfer to RBP-6300. Upon completing the study, subjects will continue their pre-study prescribed dosage of Subutex and/or Suboxone

Read the detailed description

During the open-label Run-In Period (study days -7 to -1), participants receive Subutex®/Suboxone® at one of three dose levels, depending on the dose level for that subject on entry to the study: 8 mg/day, 16 mg/day, or 24 mg/day.

During the 7-day, active drug-controlled, double-blind Transfer Period (study days 1-7), participants are randomized to either Subutex®/Suboxone® or RBP-6300 active drug at dosing levels equivalent to the level during the Run-In Period plus placebo matching the other drug.

This is followed by a 3-day single-blind Subutex®/Suboxone® Transition Period in which participants receive the same dose given during the Run-In Period.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RBP-6300Drug

    Also called buprenorphine hemiadipate HCl, naloxone HCl

    Participants randomized to the RBP-6300 treatment arm take either 10, 20 or 30 mg/day RBP-6300 tablets during the Transfer Period (study days 1-7).

    Oral RBP-6300 tablets containing 10 mg buprenorphine hemiadipate HCl and 10 mg naloxone HCl dehydrate.

  • Subutex®/Suboxone®Drug

    Also called buprenorphine, naloxone

    Participants randomized to the Subutex®/Suboxone® treatment arm take the dosage of either drug on which they were previously stabilised during the Run-In, Transfer, and Transition Periods.

    Participants randomized to the RBP-6300 treatment arm take the dosage of either drug on which they were previously stabilised during the Run-In and Transition Periods.

    Sublingual Subutex® tablets containing 8 mg buprenorphine and and sublingual Suboxone® tablets containing 8 mg buprenorphine and 2 mg naloxone.

  • Placebo for RBP-6300Drug

    Also called placebo

    Participants randomized to the Subutex®/Suboxone® treatment arm take Placebo for RBP-6300 during the Transfer and Transition Periods.

    Participants randomized to the RBP-6300 treatment arm take Placebo for RBP-6300 during the Transition Period.

  • Placebo for Subutex®/Suboxone®Drug

    Also called placebo

    Participants randomized to the RBP-6300 treatment arm take Placebo for Subutex®/Suboxone® during the Transfer Period.

What is being measured

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

  1. Treatment

    To demonstrate that RBP-6300 is not inferior to Subutex/Suboxone as assessed by the peak change from baseline in the pre-dose COWS score during the double-blind transfer phase

    Measured: 7 days

Secondary outcomes (1)
  1. Assess the overall clinical response to RBP-6300

    One of the secondary objectives is to evaluate the safety and tolerability of RBP-6300 in terms of adverse events

    Measured: one year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RBP-6300 and Subutex®/Suboxone® in people with Opioid Related Disorder, run by Indivior Inc. at 15 sites in 4 countries.

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 4 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 20 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in Germany, Austria, Czechia, Sweden. 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?

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?

Treatment (time frame: 7 days). 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 20 Jan 2017.
