About this study

Official title: Alcoholism and Schizophrenia: A Translational Approach to Treatment

Note: In June 2013, the study design was changed from a randomized controlled study of risperidone + despiramine vs. risperidone vs. placebo to an open label pre-post study of risperidone (or risperidone-like drug) + desipramine. The aims of the study were revised to read:

  1. To determine whether participants treated with risperidone in combination with desiprmaine have less alcohol use (fewer drinking days; fewer heavy drinking days) during the final 8 weeks on these medications as compared to pre-baseline. The primary hypothesis is that compared to pre-baseline, participants will demonstrate fewer days of drinking (per week), as well as fewer days of heavy drinking (per week) in the final eight weeks they are taking risperidone and desipramine, as recorded on the Timeline Follow-Back assessment
  2. To explore changes in symptoms (of schizophrenia and of depression) in the final eight weeks of treatment with risperidone + desipramine compared to the period before baseline
  3. To assess the side effect burden associated with the combination of these two medications in participants.

The original aims of the study were:

The purpose of this study is to determine whether participants who are treated with risperidone in combination with desipramine have less alcohol use (fewer drinking days; fewer heavy drinking days) than do participants who are treated with RISP with placebo. The primary hypothesis is that compared to treatment with risperidone, participants randomized to a combination of risperidone plus desipramine will have fewer days of drinking, as well as fewer days of heavy drinking. The study will also compare the effects of risperidone as compared to risperidone plus desipramine on participants' symptoms and side effects.

Read the detailed description

Alcohol use disorder is at least three times more common in schizophrenia than in the general population, and worsens the course of schizophrenia. Typical antipsychotic agents are of limited value in controlling alcohol use in these "dual diagnosis" patients. Data from our group and others suggest that the atypical antipsychotic drug clozapine limits alcohol and cannabis use in "dual diagnosis" patients with schizophrenia much more effectively than other antipsychotics that have been assessed, however, the side effects produced by clozapine severely limit its use.

The investigators have hypothesized that clozapine will lessen alcohol/substance use in such dual diagnosis patients in part because of its mechanism of action that includes release of dopamine (DA) in the prefrontal cortex which will help to normalize dysfunctional brain reward circuits that may underlie the co- occurring alcohol/substance use in patients with schizophrenia. Our data suggest that the effect of clozapine can be duplicated in rodents when medications with clozapine-like activity (DA D2 antagonism, potent norepinephrine (NE) α2 receptor antagonism and NE reuptake inhibition) are combined together. The investigators have demonstrated that RISP (a medication that is both a DA D2 receptor antagonist, and a potent NE α2 receptor antagonist), in combination with the specific NE reuptake inhibitor desipramine, significantly decreases alcohol consumption in alcohol drinking rodents.

This translational study is a pilot "proof of concept" 14-week double-blind investigation of participants who have co-occurring diagnoses of schizophrenia and an alcohol use disorder. Patients not treated with risperidone (or a risperidone-like agent, including risperidone long-acting, paliperidone and paliperidone palmitate) at the time of consent will be switched to oral risperidone in the first two weeks of the study. At Week 3, all participants will begin treatment with risperidone risperidone plus desipramine and followed for 12 weeks. The primary outcome measure will be days of drinking (per week), as well as days of heavy drinking (per week). The investigators anticipate that data from this study will support a larger trial of risperidone + desipramine in patients with schizophrenia and an alcohol use disorder.

Risperidone + DesipramineExperimentalAll participants will be treated with risperidone (or a risperidone-like agent including: risperidone long-acting, paliperdione, and paliperidone palmitate) at the time treatment with desipramine is initiated. The target dose of oral risperidone is 4mg though variations are allowed. The target dose of desipramine is 100mg.

What is being measured

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

  1. Timeline Followback Assessing Number of Drinks Per Week

    Alcohol/other substance use (including tobacco) will be assessed primarily by weekly self-report using the Timeline Followback (TLFB) method enhanced by procedures to strengthen the reliability and validity of this measure. It involves asking participants to retrospectively estimate their alcohol and other substance use.

    Measured: Weekly for 14 weeks, using data from last 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Risperidone + Desipramine in people with Schizophrenia and Alcoholism, run by Dartmouth-Hitchcock Medical Center 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 5 inclusion and 5 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 23 Mar 2018. 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. 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 23 Mar 2018). 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?

Timeline Followback Assessing Number of Drinks Per Week (time frame: Weekly for 14 weeks, using data from last 8 weeks). 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 23 Mar 2018.
