Clinical Trial Summary

A dose escalation study to assess the efficacy and safety of Clavulanic Acid (CLAV) vs. placebo (PBO) for the treatment of cocaine use disorder (CUD)


Description:

This pilot study is indicated for treatment of moderate to severe cocaine use disorder. It is a randomized, placebo-controlled, parallel group, multi-center pilot study to compare the efficacy of 500-750mg/day clavulanic acid vs. placebo in addition to weekly medication management therapy. Subjective, cognitive, and adverse effect assessments, blood pressure and pulse will be performed 1-3 times weekly.

Outcome

Type Measure Description Time frame Safety issue
Other Changes in withdrawal symptoms over weeks 1, 2, 3 will occur in CLAV vs PBO group Withdrawal symptoms will be measured using the Cocaine Selective Severity Assessment (CSSA) Weekly for 3 weeks
Other Executive control will change more in the CLAV group compared with the PBO group after 12 weeks Delay discounting will measure executive control Baseline, week 4, week 8, week 12
Other Adverse Childhood Experiences (ACE) may correlate with cocaine relapse Relationship between baseline scores from the ACE scale and abstinence outcomes in CLAV group will be compared to PBO group Baseline, week 12, follow-up
Primary Changes in relapse to cocaine use in CLAV group vs PBO group Cocaine-free weeks are measured by self-report using Timeline Follow Back (TLFB) and confirmed by urine drug screen. Last 3 weeks of 12 week study
Secondary Changes in weekly abstinence in the CLAV group vs. PBO group Abstinence from cocaine by week will be measured by self report and urine drug screen Self reported cocaine use and Urine Drug Screen (UDS) will be administered 1-3 times per week and at follow-up
Secondary Changes in weekly cocaine use will be greater in the CLAV group vs. PBO group Cocaine-free visits are measured by self-report using TLFB confirmed by urine drug screen TLFB and UDS will be administered 1-3 times per week and at follow-up
Secondary Changes in subject health and function, quality-of-life, will be greater in the CLAV group vs. PBO group Medical Outcomes Study Quality of Life Scale short form 36, will determine whether CLAV treatment is associated with improved QOL Baseline, week 4, week 8, week 12
Secondary Clavulanic acid 500-750 mg/day for 12 weeks will be safe and reasonably well tolerated Safety and tolerability as assessed by the rates of occurrence of adverse events (AEs) and the severity 1-3 times per week and at follow-up
Secondary Cocaine craving will be decreased more by CLAV vs. PBO Changes in craving will be greater in the CLAV group compared with PBO group, as measured by the cocaine craving questionnaire (CCQ), adjusted for baseline and sex 1-3 times per week and at follow-up
