- Lead Sponsor
- Assistance Publique - Hôpitaux de Paris
- Brief Summary
Randomized clinical trial of 10 days Cannabidiol versus placebo as an adjunctive treatment during inpatient alcohol detoxification to improve abstinence in patients with severe alcohol use disorder.
- Detailed Description
Secondary objectives :
* To assess the safety of 10 days of up to 900 mg of cannabidiol as an add-on to usual care in the specific population of patients with severe alcohol use disorder during inpatient alcohol cessation
* In case of relapse, reducing alcohol use after discharge up to week 6 of the study
* To reduce alcohol withdrawal symptoms during inpatient alcohol cessation
* To reduce anxiety symptoms during inpatient alcohol cessation
* In a sub-group of patients: describe CBD plasmatic rate and test if it is correlated with side-effects and/or efficacy
* In the sub-group of patients with co-occuring cannabis use, reducing cannabis use after discharge up to week 6 of the study
Secondary endpoints :
* symptoms check list (PRISE-M) of possible side effects every day from day 1 to 10, and then at each outpatient study visit (4 (1 per week) after discharge up to week 6 of the study). Thus any side effect related to treatment exposure as well as treatment cessation (such as anxiety rebound or withdrawal symptoms related to CBD or increase in cannabis use) could be documented
* in case of relapse: drinking days and drinks per day (self-declared using standardized TLFB time line follow back scale over the past week) at the screening visit and daily from Day 0 to Day 10 and 4 (1 per week) after discharge up to week 6 of the study)
* alcohol withdrawal scales and craving scales (CIWA-R, , LIKERT craving scale and an adapt version of the OCDS) at the screening visit and every day from day 0 to 10 then at each study visit: 4 (1 per week) after discharge up to week 6 of the study
* state anxiety scale (STAI-6 the short form of the Spielberger inventory, composed of 6 Likert scales) at the screening visit and every day from day 0 to 10 then at each study visit: 4 (1 per week) after discharge up to week 6 of the study
* Pittsburgh Sleep Quality Index (PSQI) at the screening visit and the last visit. A modified daily version every day from day 0 to 10 then at each study visit a modified weekly version: 4 (1 per week) after discharge up to week 6 of the study
* in the subgroup of patients recruited in Fernand Widal hospital, plasmatic level of CBD will be determined twice: at D5 and D10 of the study by Dr Laurence Labat, head of the toxicology department of Lariboisière hospital. Analysis of cannabinoids in human biological specimens of plasma will rely on an extraction process and a chromatographic separation in LCMSHR (Liquid chromatography coupled to high resolution mass spectrometry) for quantification of Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), 11-hydroxy Δ9-tetrahydrocannabinol (11-OH THC) and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) using deuterated molecules as internal standard. The method was validated in the two biological matrix according to guidelines set forth by COFRAC (Comité d'accréditation Français)
* self-declared current use of all other substances including tobacco products and nicotine replacement therapies, cannabis, and other substances using standardized TLFB (time line follow back) scales ) at the screening visit and every day from day 0 to 10 then at each study visit: 4 (1 per week) after discharge up to week 6 of the study
* in the subgroup of patients who declare themselves as current cannabis users at entry, urinary quantitative determination of cannabinoids by an extraction process and a chromatographic separation in LCMSHR (Liquid chromatography coupled to high resolution mass spectrometry) for quantification of Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), 11-hydroxy Δ9-tetrahydrocannabinol (11-OH THC) and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) using deuterated molecules as internal standard. The method was validated in the two biological matrix according to guidelines set forth by COFRAC (Comité d'accréditation Français). This analyse will be centralized in the toxicology laboratory of Lariboisière hospital (Pr Laurence Labat). This analyse will be performed 6 times: 2 during the inpatient stay (D5 and D10) and 4 (1 per week) after discharge up to week 6 of the study.
DESIGN
Double Blind Randomized clinical trial with 3 arms :
Patients will undergo one or several outpatient screening visits between D-30 and D-1 of inpatient entry.
During this visit, the study design will be fully explained, inclusion and exclusion criteria checked. Patients will be included during this last visit. Three groups of 70 patients each will be randomized 1:1:1 at entry of a scheduled, usually lasting between 11 and 17 days, alcohol inpatient cessation (D0).
They will all receive oxazepam plus an intervention:
* add-on placebo for 10 days during their inpatient stay
* add-on cannabidiol 450 mg per day for 10 days during their inpatient stay
* add-on cannabidiol 900 mg per day for 10 days during their inpatient stay. All groups will undergo the same prospective follow up after discharge with one visit per week to determine if alcohol abstinence is maintained, up to 1-month post-discharge (week 6 of the study).
In case of a relapse, the amount of alcohol used will be recorded.
