酒精使用障碍(AUD)是一种慢性复发性疾病,复发率高,因此,
非常需要开发和评估新的治疗方法来减少复发和改善酒精使用
以澳元计算。我们以前进行了一个新的剂量发现人体实验室,安全性和试点疗效
一项研究,以评估是否神经活性类固醇(NAS)的前体双烯醇酮(PREG),影响
GABA能功能可能使酒精相关的应激障碍正常化,并改善酒精使用的结果,

使慢性酒精相关的应激生物学破坏正常化,并减少每天的饮酒量
在一个8- 10岁的受试者中,与安慰剂(PBO)相比,

英文摘要
PROJECT SUMMARY/ABSTRACT
Alcohol Use Disorder (AUD) is a chronic relapsing illness associated with high rates of relapse, and thus, there
is great need to develop and evaluate novel treatments to decrease relapse and improve alcohol use
outcomes in AUD. We previously conducted a novel dose finding human laboratory, safety and pilot efficacy
study to assess whether the neuroactive steroid (NAS) precursor pregnenolone (PREG) that influences
GABAergic functioning may normalize alcohol-related stress disruption and improve alcohol use outcomes in
AUD. Pilot data showed that PREG at 300mg/day reduced stress- and cue- induced alcohol craving, anxiety
and normalized chronic alcohol-related disruption in stress biology and also reduced alcohol drinks/day
(AvgD), percent drinking days and heavy drinking days (%DD and %HDD) compared to placebo (PBO) in an 8-
week clinical study. On the basis of these findings, this project proposes a 12-week double blind, randomized
Phase II clinical trial to evaluate the safety and efficacy of PREG treatment (300 mg/day) versus PBO in 150
AUD men and women. The following specific aims will be addressed: Aim #1: To establish the safety and
tolerability of PREG (300mg/day) vs. PBO in men and women with AUD over the 12-week treatment period
and at the 1-month follow up. Aim #2: To test the efficacy of PREG vs. PBO on the primary alcohol use
outcome of PSNHDD and secondary drinking outcomes of HDD%, DD% and AvgD during the trial. Aim #3: To
assess the effects of PREG vs. PBO on other secondary stress-related outcomes of alcohol craving, anxiety,
depression and patient-related functioning during the trial. Aim #4: To assess the effects of PREG vs. PBO on
PREG and other NAS levels and examine their relationship to primary and secondary alcohol use and related
outcomes. Exploratory Aim 1: To assess enduring short-term treatment effect of PREG vs. PBO on primary
and other secondary outcomes at a 1-month post-treatment follow-up. Exploratory Aim 2: To explore whether
pre-treatment patient characteristics (sex, trauma history, AUD severity and co-occurring psychiatric disorders)
influence PREG effects on primary and secondary outcomes. It is well known that chronic alcohol use
downregulates GABA which plays a significant role in the stress pathophysiology of AUD and also in loss of
control drinking. The proposed study is based on our novel preliminary findings and will test our innovative
approach of boosting endogenous neuroactive steroid levels to increase their function and thereby improve
AUD outcomes. If successful, the proposed research will establish PREG and neuroactive steroids as key
targets in the treatment of AUD, and also provide data on neuroactive steroid levels and whether they may
serve as biomarkers in AUD treatment.
