Interdisciplinary Study of Two Novel Anticonvulsants in Alcoholism
This is a double-blind, placebo-controlled, parallel group design study with 4 treatment groups; levetiracetam, zonisamide, topiramate, and placebo control. Subjects will receive study medications for 14 weeks. Potential subjects will be initially screened for interest in study participation and alcohol consumption level to determine basic eligibility by telephone, or in person. Individuals who meet telephone screening criteria will be scheduled for a clinic appointment to obtain informed consent and conduct screening assessments. Subjects who report average drinks per day that are within the guidelines for safe levels of alcohol consumption (i.e. 2 drinks/ day males; 1 drink/day females-HHS standard) in the two weeks prior to screening will be excluded. Subjects meeting screening criteria will be scheduled for a second randomization visit. During this visit baseline assessments will be obtained. Eligible subjects will then be randomized to a treatment group and will be provided with the first week's study medications. The goal is to directly compare the efficacy and tolerability of two novel anticonvulsants, zonisamide and levetiracetam, with placebo, and using topiramate, which has extensive evidence supporting its efficacy in alcoholism, as a positive control group. We believe that this will be the first direct comparison of these agents in alcoholism, and the results will provide information on the efficacy and safety of the medications.
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
|Official Title:||A Double-Blind, Placebo-Controlled, Parallel Group Design Trial of; Levetiracetam, Zonisamide, Topiramate, and Placebo Control for the Treatment of Alcohol Dependent Subjects.|
- The primary efficacy measure is the mean number of drinks consumed per day over the period from treatment weeks 10 through 12 when all study medications should be at their maximum steady levels based on their known pharmacokinetic properties. [ Time Frame: Weeks 10 through 12 ] [ Designated as safety issue: No ]
- the secondary outcome measure is to address neurobehavioral toxicity, the mean levels of attention and verbal fluency and a composite measure of neurotoxicity will be compared between groups. [ Time Frame: 21 weeks ] [ Designated as safety issue: Yes ]
