Other specific exclusionary disorders include;
  • History of clinically significant renal calculi or renal failure; a significant indication of renal compromise will be defined by an elevation of serum creatinine above the investigators' laboratory's limit of normal, or a known history of renal failure or chronic renal disease, or any current or chronic disease that could reasonably be expected to result in renal failure
  • History of hypersensitivity to ZNS or any sulfonamide, Stevens-Johnson Syndrome, penicillin allergy, or history of any severe drug allergic reaction; History of systemic autoimmune disease such as lupus erythematosis, fibromyalgia, or rheumatoid arthritis;
  • Current blood dyscrasia or a history of such, with the exception of a past history of iron deficiency anemia

  • Use of any of a number of medications that might prominently influence drinking patterns or cause risk of harm or injury (e.g., topiramate, disulfiram, naltrexone, acetazolamide, stimulants such as amphetamine, or tramadol; Schizophrenia, bipolar disorder, PTSD, or substantial suicide or violence risk (i.e., can't be managed safely in the outpatient setting) on the basis of history or psychiatric examination; j) currently dependent on opioids or benzodiazepines or other sedatives
  • Considered by the investigators to be clinically inappropriate for study participation or have participated in another pharmacotherapy study in the past thirty days

About this study

This is a randomized, placebo-controlled, double-blind, 16 week trial of the medication zonisamide for the treatment of heavy drinking alcoholic civilians.

Read the detailed description

This is a 16-week randomized, double blind, placebo-controlled trial designed to determine the effectiveness of zonisamide treatment for reducing heavy drinking and overall drinking in 160 treatment-seeking, regularly heavy drinking, alcohol-dependent civilians who want to quit drinking or reduce consumption to non-hazardous levels. The investigators will use state-of-the-art methodology and outcome assessments, including medical management (MM) therapy (a minimal behavioral intervention aimed at reinforcing treatment goals and adherence to medication), which is simple and easily implemented in primary care settings. The use of MM in the study will increase the generalizability of results, allowing a more accurate assessment of zonisamide's effectiveness than if a more intensive behavioral intervention were to be used. To demonstrate zonisamide's effectiveness in a representative civilian sample, the investigators will include civilians with co-morbid mood and anxiety disorders.

Study groupRoleWhat they receive
ZonisamideExperimentalSubjects will receive zonisamide titrated to a target dose of 500mg orally, daily, double-blind (Titration of dose to 500mg oral, daily, over 7 weeks, then 9 weeks of treatment at that dose). Subjects may increase their dose to 600mg daily during the target treatment period if it is thought to be beneficial.
Receives: Drug: Zonisamide
PlaceboPlacebo comparatorPatients will receive placebo pills that are made to match the zonisamide medication (via over-encapsulation, double-blind, subjects will receive same number of capsules as the active medication group)

What is being measured

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

  1. Number of Drinks Per Week

    Difference between groups in the number of total standard drinks per week over 8 weeks (weeks 9-16, the weeks on the target dose) performed using a mixed models longitudinal analysis.

    Measured: over 8 weeks (weeks 9-16)

Secondary outcomes (6)
  1. Percentage of Subjects With No Heavy Drinking Days

    percentage of subjects with no heavy drinking days (PSNHDD) The PSNHDD can be derived from each subject's Timeline Followback (TLFB) data.

    Measured: over the last 8 weeks (weeks 9-16)

  2. Gamma Glutamyl Transferase (GGT) Levels

    Difference between groups on levels of GGT over time from baseline to endpoint, which will includes two interim data points for a total of four time points. This will analyzed with a mixed models longitudinal analysis (repeated measures). Levels are in Units per Liter.

    Measured: over 16 weeks (weeks 1-16)

  3. Number of Heavy Drinking Days Per Week

    The difference in the number of heavy drinking days per week compared between groups (zonisamide and placebo) for the last 8 weeks of treatment (during the time spent on the target dose of the medication). Performed using a mixed models longitudinal analysis (repeated measures).

    Measured: over the last 8 weeks (weeks 9-16)

  4. Change in Alcohol Urge Questionnaire Score (AUQ)

    This is the change in AUQ scores (urge to drink) measured weekly compared between groups using repeated measures

    Min value: 8 Max value: 42 higher score = worse craving

    Measured: over 16 weeks (weeks 1-16) and at 2 week and 3 month follow up

  5. Change in Quality of Life

    Change in quality of life scores measured by the Q-LES-Q. ' Min: 16 Max: 80 Higher Scores = Higher Life Enjoyment

    Measured: over 16 weeks (weeks 1-16) and at 2 week and 3 month follow up

  6. Level of Alcohol-related Problems

    level of alcohol-related problems measured by the Short Index of Problems (SIP), total score

    Min score: 0 Max Score: 45 Higher score= more problems

    Measured: over 16 weeks (weeks 1-16) and at 2 week and 3 month follow up

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zonisamide in people with Alcohol Use Disorder, run by Virginia Commonwealth University at 4 sites 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 4 inclusion and 8 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 13 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 13 Oct 2022). 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?

Number of Drinks Per Week (time frame: over 8 weeks (weeks 9-16)). 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 13 Oct 2022.
