About this study

Official title: The Effects of VIVITROL® on Alcohol-Related Cue-Induced Craving and BOLD [Blood Oxygen-level-dependent] Functional Magnetic Resolution Imaging (fMRI) Signal Activation Patterns

This was a study of the effects of VIVITROL® on alcohol cue-induced craving and the associated brain activation patterns in alcohol-dependent adults who had recently completed alcohol detoxification and were seeking further treatment for their alcohol dependence. The study was powered to to detect whether VIVITROL attenuates or blocks the BOLD signal increases in response to alcohol-related cues.

In the double-blind portion, subjects received a single administration of study drug (VIVITROL 380 mg or placebo). Subjects who completed the double-blind portion could opt to continue to the open-label portion and receive 2 additional months of treatment with VIVITROL 380 mg.

Read the detailed description

The double-blind phase consisted of 6 visits over a 5- to 6-week period and included 2 telephone contacts and 2 functional magnetic resonance imaging (fMRI) scans.

The optional open-label extension included 2 visits approximately 1 month apart. Subjects who completed both phases participated in a total of 8 scheduled visits (including 2 fMRI scans and 2 telephone contacts) over a period of up to 14 weeks.

At screening, eligible, consenting subjects were given an Actiwatch®-Score device. They were instructed to record their alcohol craving using this device throughout the double-blind phase. The Actiwatch was programmed to beep every 3 hours ±20 minutes, thereby signaling the subjects to enter their craving or desire to use alcohol, at that exact moment, on a scale of 0 to 10 (with 0 being no craving at all and 10 being extreme craving). In addition, subjects entered any drug and/or alcohol use at the time of occurrence. The Actiwatch was not utilized in the open-label portion of the study.

What is being measured

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

  1. Change From Baseline in Blood Oxygen-level-dependent (BOLD) Signal Activation Values Detected in the Reward Circuitry of the Brain in Alcohol-dependent Subjects After Presentation of Alcohol-related Cues.

    As was standard among fMRI studies conducted at the study site at the time, a change in BOLD signal in the range of 5% to 6% in anterior cingulate as measured using a 3T magnet,is considered highly significant in block-designed experiments.

    Measured: 14 days (Baseline to Day 14)

  2. Change From Baseline in BOLD Signal Activation Values for the Inferior Frontal Gyrus

    Measured: 14 days (Baseline to Day 14)

  3. Change From Baseline in BOLD Signal Activation Values in the Reward Circuitry

    Measured: 14 days (Baseline to Day 14)

Secondary outcomes (2)
  1. Change From Baseline in Obsessive-Compulsive Drinking Scale (OCDS) Score in Alcohol-dependent Subjects

    There are 14 items on the Obsessive Compulsive Drinking Scale (OCDS). The scale is scored from 0 to 40 (units). A score of 0 units indicates no obsession-compulsion with respect to alcohol (best score). A score of 40 units indicates maximum obsession-compulsion with respect to alcohol (worst score). A negative Change from Baseline value indicates an improvement. For scoring methods, see: Anton RF, Moak DH, Latham P (1995), The Obsessive Compulsive Drinking Scale: A self-rated instrument for the quantification of thoughts about alcohol and drinking behavior. Alcohol Clin Exp Res 19:92-9.

    Measured: 28 days (Baseline to Day 28)

  2. Change From Baseline in Daily Craving Score in Alcohol-dependent Subjects (Actiwatch Data)

    The Actiwatch-Score device (MiniMitter Co.) was used to collect data on daily alcohol craving. The Actiwatch device is a wrist-worn, battery-operated monitor programmed to beep every 3 hours ±20 minutes, to signal the subjects to enter their alcohol craving or desire to use alcohol at that exact moment on a scale of 0 to 10 units: 0 indicates no craving at all (best score) and 10 indicates extreme craving (worst score). A negative result for Change in Baseline at Day 28 indicates an improvement in daily craving as of 1 month after study drug administration.

    Measured: 28 days (Baseline to Day 28)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing VIVITROL 380 mg in people with Alcohol Dependence, run by Alkermes, 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?

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 11 Jul 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 7 Dec 2010). 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?

Change From Baseline in Blood Oxygen-level-dependent (BOLD) Signal Activation Values Detected in the Reward Circuitry of the Brain in Alcohol-dependent Subjects After Presentation of Alcohol-related Cues. (time frame: 14 days (Baseline to Day 14)). The study lists 3 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 NCT00511836, 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 11 Jul 2017.
