Outcome Measures
Primary Outcomes (1)
Brain Glutamate Concentration in the Anterior Cingulate Cortex (ACC) in Subjects With Cocaine Use Disorder (CUD) Treated With Escalating Doses of Clavulanate (CLAV)
Brain glutamate concentration in the ACC (based on Magnetic Resonance Spectroscopy (MRS)) will be correlated with cocaine craving (measured by Cocaine Craving Questionnaire (CCQ)) in subjects receiving escalating doses of CLAV for 10 days. Measurement will be made at baseline and Day 10 of CLAV (1000 mg/day) in subjects with cocaine use disorder.
ACC glutamate and CCQ will be measured and correlated on Day 10 of treatment with CLAV compared with baseline.
Secondary Outcomes (4)
Changes in Resting State Network Connectivity From Baseline
Assessment was done at the end of Period 1, 2 and 3 detailed above. Data from the end of Period 3 (Day 10, 1000mg CLAV) are reported.
Craving
CCQ-45 questionnaires were completed daily during the study. Data from day 10 adjusted for baseline score are reported.
Change in Brain Glutamine From Baseline
Brain glutamine will be analyzed at baseline (Day 1 prior to CLAV or PBO dose) and at Day 10 day (having completed Periods 1, 2 and 3 (CLAV 500mg/day for 3 days, 750 mg/day for 3 days and 1000 mg/day for 4 days).
Number of Participants With Treatment-related Adverse Events (AEs)
1-24 days (during and up to 2 weeks after study dosing period)
Study Arms (2)
Clavulanic Acid
EXPERIMENTALParticipants will receive 10 days of CLAV-- Period 1: 500 mg/day for days 1-3; Period 2: 750 mg/day for days 4-6; Period 3: 1000 mg/day for days 7-10.
Placebo
PLACEBO COMPARATORParticipants will receive 10 days of placebo and will have a "dose" escalation at the same time as the experimental group. They will be given additional placebo pills to match the number given to the experimental group (i.e. 2 PBO capsules/day for days 1-3, 3 PBO capsules/day days 4-6 and 4 PBO capsules/day for days 7-10).

Eligibility Criteria
You may qualify if:
- Be able to verbalize understanding of consent form
- Be male or female adult volunteers ages 18-65 inclusive.
- Have a Diagnostic and Statistical Manual-5 (DSM-5) diagnosis of cocaine use disorder, moderate to severe in early remission
- Have a Body Mass Index (BMI) of 17.5 to 39.9 kg/m2; and a total body weight of at least 45 kg (99 lbs.)
- Have a history and brief physical examination that demonstrate no clinically significant contraindication for participating in the study, and/ or significant or unstable medical or psychiatric illness.
You may not qualify if:
- Have a current DSM-5 substance use disorder, mild, moderate, or severe, on any drug of abuse other than nicotine, caffeine, and cocaine use disorder in early remission verified by Urine Drug Screen (UDS). Alcohol use disorder and marijuana use disorder, mild without withdrawal symptoms, will be permitted.
- Have any previous medically adverse reaction to CLAV, Augmentin, penicillin, Ticarcillin, cephalosporin, or any beta-lactam drug.
- Have any illness, condition, and use of medications, in the opinion of the principal investigator, sub-investigators which would preclude safe and/or successful completion of the study.
- Report having human immunodeficiency virus (HIV) infection or test positive for HIV during screening
- Be pregnant (females).
- Unable to tolerate MRI scan for duration of 60 minutes for physical or psychological reasons.
