Nalmefene, Baclofen and Impulsivity in Subjects With Alcohol Use Disorder and Healthy Control Subjects...
Alcohol Use DisorderImpulsivity is a central feature of addiction. Nalmefen is an authorized treatment for alcohol addiction. Baclofen has empathically been advocated to have some efficacy in this indication. The aim of the present study is to test the effect of Nalmefene and Baclofen on impulsivity. Primary study objective: To examine the effect of Nalmefene and Baclofen on impulsivity (as measured by the Stop Signal Task) in subjects with alcohol use disorder and healthy control subjects. Main secondary study objectives: To examine the effect of Nalmefene and Baclofen on risk taking (as measured by the Balloon Analogue Risk Task) and on the preference for small immediate rewards over large delayed rewards (as measured by the Delay Discounting Task). To compare subjects with alcohol use disorder and healthy control subjects on these tasks. Primary study outcome: Stop-signal reaction time in the Stop-Signal Task Main secondary study outcomes: Equivalence point in the Delay-Discounting Task and Average number of pumps delivered in the Balloon Analogue Risk Task Study Design: Randomized, placebo control, cross-over, single-dose
Cannabidiol as a Treatment for AUD Comorbid With PTSD
Alcohol Use DisorderPost Traumatic Stress DisorderThis project aims to determine whether cannabidiol (CBD), a compound derived from the cannabis plant, is effective in treating alcohol use disorder (AUD) in individuals with comorbid posttraumatic stress disorder (PTSD). Investigators will test the hypothesis that oral cannabidiol (CBD) will reduce alcohol drinking in individuals with AUD comorbid with PTSD. To test this hypothesis, 48 otherwise healthy adult participants with moderate or severe AUD and PTSD will be randomized to treatment with either CBD (600 mg daily) or placebo, for a period of 6 weeks, such that both participants and study staff are blind to treatment condition. Participants (each treated for 6 weeks) will be continuously recruited over a study period of 14 months until 48 have completed. Baseline and weekly data will be collected on alcohol usage and PTSD symptoms, and investigators will assess whether CBD treatment leads to a greater improvement in these measures relative to placebo, and whether reduction in alcohol drinking is temporally linked to improvement in PTSD symptoms. Subjects will also participate in a task designed to quantify the psychological and physiological links between negative emotion produced by re-experiencing PTSD trauma, and alcohol craving. The task will be administered following 4 weeks of treatment. Treatment-associated reduction in alcohol craving elicited by trauma-associated negative emotion between CBD and placebo groups will be compared. This study will be the first to test whether CBD is effective in treating alcohol addiction and in treating PTSD in humans, and the first to examine the interaction between these treatment effects. Results will serve as proof of concept and provide guidance for a future larger clinical trial. Because CBD is a safe, readily available drug, such a trial would have an immense potential to prevent death, medical illness, and psychological suffering associated with AUD and PTSD. Further, because the brain circuits via which CBD acts to produce hypothesized effects are relatively well-understood, results may substantially advance understanding of the neurobiological basis of alcohol addiction.
Cognitive Training in the Treatment of AUD
Alcohol Use Disorder Cognitive DeclineAlcohol Use Disorders (AUDs) have a significant public health impact and are highly prevalent in Veterans. Alcohol related brain effects on neurocognition (attention, memory and executive function) reduce ability to benefit from current treatments. These cognitive impairments are especially common in the early phase of recovery, persist over years and get worse with age. Recent research suggests that cognitive remediation therapy (CRT) may improve attention, memory and executive function in other disorders, and the investigators just completed pilot study with AUD Veterans found significantly greater improvements for those receiving CRT. The proposed study examines AUD outcomes and neurocognitive improvements when CRT is combined with a standardized alcohol treatment. The investigators hypothesize that CRT will improve neurocognition and AUD outcomes more than standardized alcohol treatment alone. Findings will determine whether CRT augmentation can benefit Veterans with AUDs.
Smartphone Based Continuing Care for Alcohol
Alcohol AbuseInvestigators will recruit 280 alcohol dependent patients in treatment programs in the Philadelphia area to test the efficacy and cost efficiency of a smartphone based application for treating alcohol addiction (ACHESS) with telephone monitoring and counseling (TMAC). Participation in the study lasts for 18 months with research visits at baseline, 3 months, 6 months, 9 months, 12 months, and 18 months. The intervention lasts 12 months.
Lifestyle Physical Activity Intervention for Depressed Alcohol Dependent Women
Alcohol DependenceBuilding on the large body of evidence for the effect of exercise in decreasing depressive symptoms and the few preliminary findings of its effect on craving and drinking outcomes, the purpose of this study is to develop a lifestyle physical activity (LPA) intervention that harnesses the technological advantages of the Fitbit tracker (plus its web and mobile platforms) for depressed women with alcohol use disorders (AUDs). The intervention will provide women with an acceptable, flexible and effective alternate coping strategy during early recovery, when relapse risk is highest. The overall objective of this work is to fully develop this LPA+Fitbit intervention, modify it based on initial piloting and feedback to ensure its feasibility and acceptability for depressed women with AUDs in early recovery, propose potential mechanisms of its effect, and to obtain preliminary data on its efficacy.
Can Cognitive-bias Modification Training During Inpatient Alcohol Detoxification Reduce Relapse...
Alcohol DependenceIt is well-established that many substance misusers experience impairment in cognition (thinking skills), particularly those needed to regulate and monitor behaviour and ensure that goals are achieved. According to the dual-process model, addiction arises from an imbalance in 'bottom-up' processing i.e., overactive automatic (impulsive) processes that drive behaviours and impaired 'top-down' controlling processes that stop behaviours associated with negative consequences. As a result, the individual becomes more sensitive to cues in their environment (e.g., alcohol images) that trigger the addictive behaviour. Cognitive-bias modification (CBM) is a novel, computer-based training paradigm that trains the brain to pay less attention to negative/harmful cues and more attention to positive or neutral cues. This approach minimizes the overactive 'bottom-up' processes and improves the 'top-down' control processes of unhealthy behaviors which enables the addicted individual to make better decisions. Recently, CBM has been used with addicted population to alter the tendency to approach alcohol, with one German study showing that a 4-session training programme was associated higher rates of abstinence at one-year (Wiers et al., 2011). The current study examines whether a novel computer based training programme alters cognitive biases (the tendency to approach alcohol related stimuli) in alcohol-dependent inpatients, and examine whether this enables them to be better at decision-making more generally, and its impact on craving and post-discharge abstinence rates. The study will also explore whether individual differences in impulsivity and sensitivity to reward and punishment determine response to the training programme. This will be achieved using a parallel-groups randomized superiority trial design involving approximately 80 patients attending inpatient withdrawal programmes in Victoria. The findings are likely to have implications for the design and delivery of psychosocial interventions delivered during early recovery from alcohol-dependence to optimise treatment effectiveness.
Clinical Medication Development for Bipolar Disorder and Alcohol Use Disorders
Alcohol Use DisorderBipolar DisorderPreclinical and clinical data as well as mechanistic justification have been presented suggesting citicoline and pregnenolone are each promising treatments for alcohol use in BPD. Both appear to have favorable side effect profiles and no known drug-drug interactions. Thus, they have the potential to be safely used in a dual diagnosis population already taking other medications. A 12-week, randomized, double-blind, parallel-group, placebo-controlled adaptive design study of citicoline and pregnenolone is proposed in 199 persons with alcohol use disorder and bipolar I or II disorder or schizoaffective disorder (bipolar type). The primary aim will be to assess change in alcohol use. Biomarkers of alcohol use, alcohol craving, mood and cognition will also be assessed. Relationships between neurosteroid and choline levels and the outcome measures will be explored.
Remote Brief Intervention and Referrals to Treatment Service for Alcohol
Alcohol AbuseAlcohol DependenceThe traditional paradigm that relies upon training physicians and nurses or uses on-site interventionists to perform screening, brief intervention, and referral to treatment (SBIRT) for alcohol has proven unsustainable in most clinical settings. The Remote Brief Intervention and Referral to Treatment (R-BIRT) for alcohol is an innovative telehealth service model with potential to improve public health through evidence based counseling for patients who exceed the NIAAA low risk drinking limits or have evidence of an Alcohol Use Disorder with professional and self-help treatment. For those that are appropriate, the R-BIRT service will provide facilitated referrals to specialized alcohol abuse treatment. The service model is being studied in the emergency department (ED) setting to demonstrate its utility in a medical setting with a very high prevalence of risky alcohol use and Alcohol Use Disorders; however, the model is relevant and will be accessible to a broad array of healthcare settings, including primary care practices. Our new model, the R-BIRT, challenges the prevailing paradigm and offers the promise of not only clinical efficacy but increased cost effectiveness as well.
NAC for Treating Comorbid PTSD and SUD
Posttraumatic Stress Disorder (PTSD)Alcohol Use Disorder (AUD)1 moreAs a result of sustained operations in Afghanistan and Iraq, there are an increasing number of U.S. military Veterans with substance use disorders and comorbid posttraumatic stress disorder (PTSD). If left untreated, individuals with substance use disorders and PTSD are at increased risk for developing other mental health problems (e.g., depression, anxiety), suicidal ideation and attempts, medical problems, reduced resiliency and military readiness, vocational problems, and family/social impairment. This study will determine the benefits of N-acetylcysteine (NAC) in treating alcohol use disorder and comorbid post-traumatic stress disorder (PTSD) among military Veterans.
