E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to investigate the effects of the GLP-1 receptor agonist Bydureon® on total number of heavy drinking days from baseline to follow up after 26 weeks of treatment in patients with alcohol dependence in a 26-weeks double-blinded, randomized placebo-controlled clinical trial. )). Furthermore, patients will be approached 26 weeks after end participation, in order to evaluate whether or not there is a long-term effect of the intervention on the TLFB questionnaire. |
|
E.2.2 | Secondary objectives of the trial |
We also wish to explore the neuromolecular and neuroanatomical underpinnings of the potential beneficial effects of Bydureon® treatment in the brain by use of the brain imaging techniques brain single photon emission tomography (SPECT) and functional magnetic resonance imaging (fMRI). |

E.5 End points |
E.5.1 | Primary end point(s) |
Percent reduction in total number of heavy drinking days and defined as days with an excess intake of 60/48 grams of alcohol per day (men and women, respectively) from baseline to follow-up after 26 weeks of treatment measured by the Time Line Follow Back (TFLB) method. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints include changes in total alcohol consumption (g/30 days measured by TLFB), changes in number of days without alcohol consumption and Penn Alcohol Craving Scale (PACS) score, change in Alcohol Use Disorders Identification Test (AUDIT) score, Drug Use Disorders Identification Test (DUDIT) score, change in the liver parameters gamma-glutamyltransferase (GGT), alanine aminotransferase (ALAT), and phosphatidyl-ethanol (PEth). Safety will also be evaluated through measure-ments of pancreatic function (the pancreatic parameters amylase and lipase together with clinical evaluation). Other parameters will be mean cell volume (MCV), changes in body weight, blood pressure, pulse, overall glycaemic con-trol parameters (HbA1c), kidney function (p-creatinine, eGFR and urine albu-min/creatinine ratio) and measures of health (Short Form Health Survey (SF-36), life quality (The WHO-Five Well-being Index (WHO-5)) and Symptom Checklist (SCL-92)). )). Furthermore, patients will be approached 26 weeks after end participation, in order to evaluate whether or not there is a long-term effect of the intervention on the TLFB questionnaire.
In addition to these clinical outcome parameters we will explore the possible neuromolecular effects by measuring striatal dopamine transporter (DAT) availability before and after administration of Bydureon® by use of the Single-photon emission computed tomography (SPECT). The possible neuroanatomical underpinnings of Bydureon® will be investigated by use of functional Magnetic Resonance Imaging (fMRI). These examinations will be performed in two subgroups of patients treated with either Bydureon® or placebo. To have comparable standard data of the alcohol related fMRI paradigm, we will include 25 healthy participants with no record of alcohol dependence. They will be matched with gender and age of the patients and undergo one fMRI scan. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Changes in total alcohol consumption (g/day), changes in number of days without alcohol consumption, change AUDIT score, DUDIT score, change in GGT, ALAT and PEth. Safety, (MCV), changes in body weight, blood pressure, pulse, overall glycaemic control parameters, kidney function, SF-36 and SCL-92. Striatal dopamine transporter (DAT) availability and neuroanatomical underpinnings of Bydureon®: June 2020
