About this study

Official title: Pramipexole in Bipolar Disorder: Targeting Cognition (PRAM-BD)

Converging evidence suggests that patients with bipolar disorder suffer from deficits in neurocognitive functioning that persist, despite remission of acute affective symptoms. These impairments contribute directly to functional disability, highlighting the need for interventions above and beyond standard treatments in order to achieve a full inter-episode recovery. The current study aims to investigate the safety and efficacy of a dopamine agonist (pramipexole), on these persistent cognitive abnormalities in euthymic bipolar patients using a placebo-controlled, adjunctive, 12-week trial design.

Read the detailed description

All eligible participants will undergo study visits at screening, baseline (week 0), week 1, week 2, week 3, week 4, week 6, week 8, and week 12, (end of study).

Randomization will be conducted via a computer generated program and all study staff will be blinded unless un-blinding is required for safety reasons. Subjects will be randomized on a 1:1 ratio with stratification for concomitant antipsychotic status and depression at baseline (HRSD <8 vs > 8). Study drug will be blinded and matched to placebo. Adapting from our previous work in BD and according to package labeling, the dosage titration schedule will be slow and flexible. Dosing will be initiated at 0.25 mg QHS on night one, followed by 0.25 mg BID day two onward, and increased every week to a target of 4.5 mg/day. As compared with our previous maximum 1.5 mg/day (Burdick et al. 2012), we opted to allow up to 4.5 mg/day (the maximum approved dosage in Parkinson's disease) to ensure adequate target engagement. We are familiar with this dose range, as 4.5 mg/day was allowed in our study in BD depression (Goldberg et al. 2004). Dosing will be flexible based on side effects; however, if 1.5 mg/day cannot be tolerated, the subject will be discontinued. Titration will occur up to week 6 and then efforts will be made to maintain the same dose until the completion of the trial (week 12).

What is being measured

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

  1. MATRICS Consensus Cognitive Battery

    MATRICS Consensus Cognitive Battery (MCCB) as measure of Neurocognitive/Functional Measures is a standardized battery designed to measure cognitive functioning in people with schizophrenia. The MCCB is represented as a composite T score. This T-score scale has a mean of 50 and a standard deviation of 10, where higher scores reflect better performance.

    Measured: Baseline

  2. MATRICS Consensus Cognitive Battery

    MATRICS Consensus Cognitive Battery (MCCB) as measure of Neurocognitive/Functional Measures is a standardized battery designed to measure cognitive functioning in people with schizophrenia. The MCCB is represented as a composite T score. This T-score scale has a mean of 50 and a standard deviation of 10, where higher scores reflect better performance.

    Measured: Week 6

  3. MATRICS Consensus Cognitive Battery

    MATRICS Consensus Cognitive Battery (MCCB) as measure of Neurocognitive/Functional Measures is a standardized battery designed to measure cognitive functioning in people with schizophrenia. The MCCB is represented as a composite T score. This T-score scale has a mean of 50 and a standard deviation of 10, where higher scores reflect better performance.

    Measured: Week 12

Secondary outcomes (7)
  1. Young Mania Rating Scale (YMRS)

    Mean change of symptoms of mania throughout the study. YMRS contains 7 items rated from 0 (symptom absent) to 4 (severe symptom) and 4 items scored 0 (symptom absent) to 8 (severe symptom), with total range from 0 to 60, where higher score indicates manic symptoms.

    Measured: Baseline and week 12

  2. Hamilton Rating Scale for Depression (HRSD)

    Mean change of symptoms of depression throughout the study. HRSD consists of 14 items, each defined by a series of symptoms. Each item is rated on a 5-point scale, ranging from 0 (not present) to 4 (severe), with a total score range of 0-56, where higher score indicates more depressive symptoms.

    Measured: Baseline and week 12

  3. Brief Psychiatric Rating Scale (BPRS)

    Mean change for positive symptoms throughout the study. BPRS consists of 18 items, each defined by a series of symptoms. Each item is rated on a 7-point scale, ranging from 1 (not observed) to 7 (very severe), with a total score range from 18-126, where higher scores indicate psychiatric symptoms.

    Measured: Baseline and week 12

  4. Number of Participants With Suicidal Acknowledgements

    Number of individual participants who acknowledged at least one item on the Columbia Suicide Severity Rating Scale (C-SSRS) over the 12-week study period. Examples of items on the scale are suicidal ideation (having thoughts, planning) and suicidal behavior (preparing, attempting).

    Measured: up to Week 12

  5. The Probabilistic Stimulus Selection Task

    The probabilistic selection task assesses the tendency to learn from positive versus negative outcomes. In the probabilistic stimulus selection task, participants are trained to choose one of two paired stimuli; three sets of paired stimuli are shown in total (AB, CD, and EF) and are presented randomly during the training period. To minimize verbal encoding, stimuli are Japanese Hiragana characters. Probabilistic feedback regarding the "correct" choice is provided. We report the mean percentage of accuracy on choosing the correct paired stimuli among the two treatment groups.

What is this clinical trial studying?

A Phase 4 study testing Pramipexole in people with Bipolar Disorder, run by Brigham and Women's Hospital at 3 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 11 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 28 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 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 28 Feb 2020). 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?

MATRICS Consensus Cognitive Battery (time frame: Baseline). 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 NCT02397837, which also lists 2 linked publications.

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 28 Feb 2020.
