NCT06269146

Brief Summary

This study seeks to understand if the medication pramipexole improves social connectedness and functioning in adults (ages 18-50) who experience anxiety or depression. The study plans to enroll 108 participants total across two sites (University of California San Diego and New York State Psychiatric Institute). Pramipexole will be given in a 6-week randomized, double-blind, placebo-controlled trial. Social reward processing will be assessed using measures of brain function (fMRI), behavior, and self-report at baseline and week 6. Knowledge gained from this study will help determine the therapeutic potential of targeting the dopamine system to remediate social disconnection as an anxiety and depression intervention.

Outcome Measures

Primary Outcomes (1)

  • Neural activation during social reward anticipation

    The primary outcome of interest is blood oxygen level dependent (BOLD) response during anticipation of positive valence social cues vs. baseline in the striatum region of interest (ROI) mask, defined according to a meta-analysis of the social incentive delay task.

    Baseline, week 6

Secondary Outcomes (7)

  • Neural activation during opportunities to disclose to others

    Baseline, week 6

  • Motivation to engage in shared experiences with others

    Baseline, week 6

  • Positive affect in response to the social affiliation task

    Baseline, week 6

  • Social approach goals during the social affiliation task

    Baseline, week 6

  • Social approach behavior during the social affiliation task

    Baseline, week 6

  • +2 more secondary outcomes

Other Outcomes (4)

  • Negative affect in response to the social affiliation task

    Baseline, week 6

  • Neural activation during social punishment anticipation

    Baseline, week 6

  • Social avoidance goals during the social affiliation task

    Baseline, week 6

  • +1 more other outcomes
