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

Study Arms (3)
Pramipexole 1 mg/d
ACTIVE COMPARATOREach participant will take pramipexole in identical capsular form twice daily for 6 weeks.
Pramipexole 2.5 mg/d
ACTIVE COMPARATOREach participant will take pramipexole in identical capsular form twice daily for 6 weeks.
Placebo
PLACEBO COMPARATOREach participant will take placebo in identical capsular form twice daily for 6 weeks.
Interventions
The study drug, pramipexole, is an FDA-approved medication for the treatment of Parkinson's and restless leg syndrome. Pramipexole (Mirapex) tablets are taken orally, with or without food.
Placebo will match the study drug in mode of administration, color, size, and taste.
Eligibility Criteria
You may qualify if:
- Clinically elevated levels of anxiety (OASIS ≥ 8) or depression or (PHQ-9 ≥ 10).
- Moderate or greater social disability assessed with clinician-rating (SDS - Social ≥ 5).
- Below the normative mean for temperamental reward sensitivity (ATQ - Approach \< 35).
- Age 18-50.
- Ability to provide written informed consent.
- English proficiency.
You may not qualify if:
- Current, imminent risk of suicide assessed with Clinical Interview and Columbia Suicide Severity Rating Scale (C-SSRS) "yes" response to items 4, 5 (past month), 6 (past 3 months), or suicide attempt in the past year.
- History of bipolar or psychotic disorders.
- History of major neurological disorder or moderate to severe traumatic brain injury.
- History of severe or unstable medical conditions that might be compromised by participation in the study (e.g., cardiovascular, hepatic, renal, respiratory, endocrine, neurologic or hematologic disease; history of seizure disorder).
- Past 6-month substance use disorder (any severity) with the exception of mild alcohol, cannabis, or tobacco use disorder, which will be permitted in the study.
- History of impulse control problems (e.g., pathological gambling).
- First-degree relative with a diagnosis of schizophrenia-spectrum or other psychotic disorder or bipolar disorder.
- History of cocaine or stimulant use (e.g., amphetamine, cocaine, methamphetamine; except for physician prescribed stimulants) in the past 6 months.
- History of dopaminergic agonists drug use (e.g., pramipexole, ropinirole, apomorphine, rotigotine) in the past 6 months.
- Positive urinalysis screen for psychoactive drug use (that is not physician prescribed or THC).
- Abnormal and clinically relevant blood count, liver, renal or EKG findings as determined by physician.
- Women who are pregnant, breastfeeding, or planning to become pregnant within the next 6 months. Individuals of childbearing potential must agree to use an acceptable method of contraception from at least 21 days prior to the first dose of study drug and for 3 months after the last dose of study drug for study entry.
- Concurrent empirically supported psychosocial treatments for anxiety or mood disorders (e.g., cognitive behavioral therapy).
- Use of any psychotropic medication (e.g. SSRIs, benzodiazepines) within 14 days before study entry \[except for fluoxetine within 30 days\]. Concurrent use is prohibited during the study
- Anticipated inability to attend regular study appointments.
