About this study

In plain language

This study tests whether a drug that blocks a brain receptor called NOPR can help with brain activity and choices about approaching or avoiding things. It is for people with depression or certain anxiety disorders who are not taking mental health medicines, and for healthy volunteers.

The study will investigate whether a nociceptin receptor antagonist will normalize neural and behavioral processes of approach/avoidance decision-making in unmedicated individuals with major depressive disorder (MDD) and anxiety disorders. More specifically, the study aims to investigate dysregulation within (1) corticostriatal-midbrain circuitry and (2) nociceptin/orphanin FQ peptide and the nociceptin receptor (NOPR).

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • For the depression/anxiety group: have major depression, generalized anxiety, social anxiety, panic disorder, or post-traumatic stress disorder, confirmed by a study interview.
  • For people with depression: score above 16 on the study’s depression rating scale.
  • For the depression/anxiety group: no mental health medicines for at least 2 weeks; at least 6 weeks for fluoxetine and 6 months for antipsychotic medicines.
  • For healthy volunteers: no medical, brain, nerve, or mental health illness, including alcohol or drug abuse, based on health history and an interview.
  • For healthy volunteers: no medicines for at least 3 weeks.
  • Be right-handed.
  • Have an iPhone or Android smartphone for study assessments.
  • Give written consent to join.

Who can't join

  • Pregnant, or able to become pregnant but not using medically accepted birth control.
  • Serious or unstable illness; a history of seizures; current seizure medicines; dementia; or signs of an underactive thyroid.

  • Any past use of medicines that affect dopamine, a brain chemical, including methylphenidate; or current use of other mental health medicines.
  • Any past electroconvulsive therapy, a treatment that uses electrical pulses to the brain.
  • Cannot safely have an MRI scan, or have abnormal blood or other lab tests or an abnormal ECG, a test of the heart’s electrical activity.

Simplified for readability. The official criteria below are what the study team uses.
