Cocaine Dependence, in Remission, Cocaine Abuse, in Remission, Cocaine-Related Disorders

Brief summary

The main purpose of this study is to determine how the study drug, clavulanic acid, affects glutamate in the brain using Magnetic Resonance (MR/MRI) scans. In this study, subjects will receive the study drug, clavulanic acid and undergo 4 MRI scans. This is being studied to determine the correct dosing of clavulanic acid, and to gather data so future studies can be done to find out if this drug is helpful in treating cocaine dependence. Currently, there is no available medication treatment for cocaine dependence.

Change in brain glutamine from baseline10-17 DaysChange in brain glutamine concentration in 2 brain areas at Day 10-17 compared with baseline.
Change in brain glutamine/creatine ratio from baseline10-17 DaysChange in glutamine/creatine ratio in 2 brain areas at Day 10-17 compared with baseline.
Number of participants with treatment-related adverse events (AEs) as assessed by comprehensive metabolic panel, complete blood count, ekg, urinalysis, C-SSRS, and any self-reported change in health.1-31 days (during and after study dosing period)Adverse events (AES) will be defined as any clinically significant changes in vital signs, indications of suicidal ideation or behavior on the Columbia Suicide Severity Rating Scale (C-SSRS), clinically significant change in Electrocardiogram (EKG) parameters and clinically significant changes in laboratory bloodwork (Complete blood count, comprehensive metabolic panel, urinalysis), or any self reported side effects compared with baseline. AEs will be collected throughout the study and reviewed by a physician. An evaluation of AE severity (mild, moderate, severe) will be evaluated by a physician based on participant self-report. AEs per subject will be listed by organ system, and the number of AEs within the subject population will be totaled.
