Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants with moderate to severe alcohol dependence will be allocated to one of two treatment arms:
Arm 1: everolimus 2.5 mg administered orally (tablet) once daily for 14 days
Arm 2: everolimus 5.0 mg administered orally (tablet) once daily for 14 days
The first dose level of everolimus to be tested will be 2.5mg daily. If this dose is found to be safe following analysis performed by the Data Safety Monitoring Board (DSMB), the dose will be increased to 5mg daily for the next group of participants. It is expected that up to 6 participants will be required for each arm.
The study drug will be provided during the early withdrawal phase of treatment, during admission to an inpatient withdrawal clinic. The participant will be admitted as an inpatient for up to 14 days following administration of the study drug. If the participant wishes to discharge after a minimum five day period of treatment after study medication has commenced (i.e. discharge on day 6 or later) they may complete the remainder of the treatment phase as an outpatient. Participants will be monitored daily throughout the treatment period and weekly thereafter for an additional four weeks. Comprehensive medical reviews will be performed on the first day of dosing, after 5-7 days of treatment, and on the final day of treatment (day 14). Participants will also be followed up for four weeks after treatment cessation.
Research interviews will be conducted at day 5, day 8, day 14, and at the 28 day follow up (week 6). Blood samples for safety measures will also be taken at this time. Blood samples for pharmacokinetic analysis will be taken at day 1 and day 14 of treatment, and at the 28 day follow up (day 42 of study). Participants will be asked to complete a daily diary and breathalyser testing throughout the study (weeks 1-6).

Summary
Brief summary
Alcohol use disorders are a leading cause of morbidity and mortality. Existing pharmacological treatments for alcohol use disorders have limited success rates. New research is expanding the focus of development for the treatment of substance use disorders, attempting to identify the underlying neurobiological mechanisms that maintain addiction, rather than more traditional approaches of agonist based treatments or management of acute withdrawal symptoms. Recently, a series of animal studies have shown that rapamycin, an mTORC1 inhibitor, may provide ongoing protection against the expression of addiction and relapse behaviours.

The aim of this study is to examine the safety and feasibility of everolimus, an mTORC1 inhibitor, in the treatment of alcohol dependence, whilst also looking for any change in alcohol use whilst taking the study drug and during a four week follow up period.
