DESCRIPTION (provided by applicant): Heroin use and non-medical use of prescription opioid continue to be a Public Health problem. Young adults are an especially important group because of the high rates of current use of illicit drugs (19.7 %). Opiate addiction is considered a chronic and relapsing disorder, and while agonist maintenance treatment continues to be the most common treatment for opiate dependence, the strong evidence of beneficial effects are mostly during the substitution period, but not during the post-treatment period when relapse and risk of returning to previous patterns of drug use are high. Growing preclinical evidence strongly suggests that the co-administration of an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist such as memantine with an opioid agonist may facilitate the sustainability of the opioid agonist efficacy on the mu-opioid receptor while at the same time and same animal reduce the sensitization to short-acting opiates' reinforcing effects. The purpose of this pilot clinical trial is to examine to what extent the co-administration of memantine (15mg & 30mg) to buprenorphine will improve treatment outcomes during and after treatment compared to buprenorphine alone. This 13-week clinical trial will provide treatment for 60 opioid dependent patients, aged 18-25 years, who will be randomized to three treatment conditions: (1) memantine 15mg/day + buprenorphine; (2) memantine 30mg/day + buprenorphine and (3) placebo + buprenorphine. The study will have an induction, maintenance and discontinuation phases. Baseline measures related to opioid use will be determined during the first week of treatment participation. Subjects' randomization will be balanced by severity of opioid dependence. All participants will participate in weekly group therapy. The primary outcomes will be weekly rates of self-reported use of opiates and urine toxicology during treatment with buprenorphine; rates of early relapse by self-report use of opiates and urine toxicology; and rates of side-effects and adverse events. The research proposed in this application is innovative because memantine enhanced time-limited buprenorphine therapy may become an effective alternative short-term intervention for many young adult patients. PUBLIC HEALTH RELEVANCE: Heroin use and non-medical use of prescription opioids among young adults continues to increase. Opiate addiction is considered a chronic and relapsing disorder that is effectively treated with long-term maintenance on agonist therapy. This treatment may not necessarily be the best treatment for young adults. This study is evaluating if adding memantine to buprenorphine may become an effective alternative short-term intervention for many young adult patients, and change current clinical practice for this population.

描述（由申请人提供）：海洛因使用和非医学使用处方阿片类药物仍然是一个公共卫生问题。由于目前使用非法药物的率很高（19.7％），年轻人是一个特别重要的群体。鸦片成瘾被认为是一种慢性和复发性疾病，尽管激动剂维持治疗仍然是阿片类药物依赖的最常见治疗方法，但有益作用的有力证据主要是在替代期间，但在治疗后期，当复发和返回先前药物使用模式的风险很高。越来越多的临床前证据强烈表明，非杀伤性N-甲基-D-天冬氨酸（NMDA）受体拮抗剂（如美容氨酸）与阿片类药物激动剂的共同给药可以促进阿片类药物受体的可持续性在同一时间和同一动物效应下降低了对敏感性的效果。这项试验临床试验的目的是检查纪念碑（15mg＆30mg）与丁丙诺啡的共同给药在多大程度上将在治疗期间和单独的治疗后改善治疗结果。这项为期13周的临床试验将为60名年龄18-25岁的阿片类药物依赖性患者提供治疗，他们将被随机分为三种治疗条件：（1）纪念15mg/天 +丁丙诺啡； （2）美金刚30mg/天 +丁丙诺啡和（3）安慰剂 +丁丙诺啡。该研究将具有诱导，维护和中断阶段。与使用阿片类药物有关的基线措施将在治疗参与的第一周确定。受试者的随机化将通过阿片类药物依赖的严重程度来平衡。所有参与者将参加每周小组治疗。主要结果将是每周自我报告使用阿片类药物和尿液毒理学的速率。通过自我报告使用阿片类药物和尿液毒理学的早期复发率；副作用和不利事件的速度。该应用中提出的研究具有创新性，因为美容增强的时间限制的丁丙诺啡治疗可能成为许多年轻成年患者的有效替代短期干预。 公共卫生相关性：年轻人中海洛因使用和非医学使用处方阿片类药物的使用不断增加。鸦片成瘾被认为是一种长期维持激动剂治疗的慢性疾病，可有效地治疗。这种治疗可能不一定是年轻人的最佳治疗方法。这项研究正在评估在丁丙诺啡中增加美金刚是否可能成为许多年轻成年患者的有效替代短期干预措施，并改变了该人群的当前临床实践。
