- 요약It has been 19 years since the Food and Drug Administration (FDA) approved a new medication for the treatment of alcohol use disorder (AUD). Thus, medication development is a top research priority within the field of AUD. Randomized clinical trials (RCTs) continue to represent a key scientific tool for testing the effectiveness of new interventions and examining their value in clinical practice. To best expand pharmacotherapies for AUD and improve medication utilization in clinical settings, proper design, execution, and evaluation of these trials is critical. This dissertation seeks to advance the literature on AUD clinical trial methodology, assessment, and analysis and provide recommendations for enhancing the medication development process. This aim was addressed in three parts. First, a systematic review was conducted to describe current methodological practices of AUD RCTs and extrapolate opportunities for optimization (Study 1). Next, the repertoire of clinical assessments for RCTs was expanding by developing a reliable measure of AUD severity, a demonstrated moderator of treatment response (Study 2). Lastly, a re-analysis of a combined medication RCT for AUD and smoking cessation was conducted using data-driven methods to identify treatment responders (Study 3).Study 1 (Donato et al., 2024) involved a systematic review of 139 RCTs representing 19 AUD medications, describing the main characteristics of randomized clinical trial designs. Study characteristics including sample size, outcome domain (e.g., heavy drinking, abstinence), medication dosage, inclusion factors, and treatment duration were extracted and synthesized. Results from the study demonstrated that the most frequently tested medication was naltrexone, the median length of treatment period was 12 weeks, a majority of studies included both heavy drinking and abstinence outcomes. Additionally, results indicated a positive trend in more balanced samples and better reporting of demographic characteristics over time. Empirical data from this study can be coupled with that of prior narrative reviews to provide recommendations for optimization and promote consilience. These efforts will both help in the refinement of the medication development process, as well as making it easier for information to be integrated and passed to clinicians.Study 2 (Donato et al., 2022) expanded upon prior work on an AUD severity construct to create a novel screening assessment to be implemented in RCTs. Data amassed from six psychopharmacology studies (n=1939) was used to replicate a previously validated AUD severity construct (Donato, Green, & Ray, 2021) and to develop a preliminary 9-item AUD severity scale. Exploratory factor analysis on the 9-item scale demonstrated that a single factor model of severity best fit the data. Analysis of the psychometric properties revealed good internal consistency (α= 0.79). This study supports the initial consistency and validity of a brief severity scale that can be leveraged in future RCTs and clinical settings.Study 3 (Donato & Ray, 2025) used machine learning data analytic approaches to identify key predictors of smoking cessation and drinking reduction. Data was utilized from a Phase 2, randomized, double-blind clinical trial on the combined effects of naltrexone and varenicline in a sample of daily smokers and heavy drinkers (n=165). The study tested the predictive power of three different models (i.e., ridge regression, LASSO regression, and random forest) for both smoking and drinking outcomes. Findings from the study indicated that LASSO regression performed the best with both outcomes compared to ridge regression or random forest. In both outcome analyses, indicators of co-use (e.g., alcohol consumption for smoking outcome, smoking variables for drinking outcome) were identified as significant predictors. Additionally, education came up as a key predictor of smoking cessation and drinking reduction. Overall, this study developed predictive models and identified key features that can be validated and later implemented in clinical settings to provide more personalized treatment recommendations.The successful completion of these studies has provided valuable clinical data on the medication development process, including trial methodology, novel assessment measures, and predictors associated with treatment response. Collectively, results from this series of studies can inform future clinical trial efforts and further research studies in medication development for AUD.
