Imaging Brain Interactions in Cocaine Use Disorder

This study is looking at how certain brain systems, specifically those involving nociceptive opioid peptide (NOP) receptors and cortisol/corticotrophin releasing factor (CRF), interact in people with cocaine use disorder (CUD). You would receive two PET scans (a special type of imaging) using a radiotracer called [C-11]NOP-1A, one before and one after receiving an intravenous dose of hydrocortisone (a medication). Researchers want to see how these brain interactions change and if they can predict relapse in CUD. The study aims to enroll 80 participants and is currently unclear on its recruitment status. To join, you must be between 18 and 55 years old and have a cocaine use disorder.

Study design
This interventional study plans to enroll 80 participants. It is not specified if it is randomized or blinded.
What's involved
You would undergo two PET scans, one at baseline and another 3 hours after receiving intravenous hydrocortisone.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint is measured at baseline and 3 hours post-hydrocortisone. Longer-term follow-up is not specified.

  • DELTA VTBaseline, and 3 hours post-hydrocortisone

    VT is the volumes of distribution expressed relative to total plasma ligand concentration; Delta VT is the change in VT from baseline to 3-hours post-hydrocortisone.
