项目摘要
The number of individuals with Opioid Use Disorder (OUD) continues to rise with more than 2.5 million
affected, along with substantial morbidity and mortality. Several effective medications are available to treat
OUD with buprenorphine becoming the primary medication used in the community. Buprenorphine is effective
for approximately 50-70% of patients and better results are achieved with the longer duration of treatment.
However, the prospect of long-term opioid maintenance is not acceptable to some patients and they eventually
request to stop treatment or discontinue it on their own. As many patients who had good treatment response
desire to discontinue the medication there is a need to collect evidence about the best strategy to accomplish
that. Opioid receptor antagonist naltrexone is approved for relapse prevention following detoxification off
opioids. Naltrexone can be started as a first-line treatment following discontinuation off illicit opioids and it may
also be used as an adjunct for patients who wish to discontinue buprenorphine maintenance and would like to
be protected from relapse. We propose an open-label randomized outpatient trial to evaluate feasibility and
efficacy of rapid BUP discontinuation followed by brief course of treatment with long-acting naltrexone (XR-
NTX) and to compare it to the standard method of gradual BUP taper.
Individuals with OUD (N=55) who have successfully completed at least 6 months of buprenorphine treatment
and do not wish to remain in a long-term buprenorphine maintenance program will be recruited. The first phase
includes a 4-week period of stabilization on buprenorphine 4-8 mg at the research clinic to assure that patients
are stable, compliant, and free from illicit opioids. Participants that meet the above criteria will be randomized
1:1 to: 1) buprenorphine discontinuation and outpatient transition to XR-NTX with 3 monthly injections, or 2)
buprenorphine discontinuation using a gradual, 5-week long taper. In both groups participants will receive
weekly relapse prevention therapy and will be monitored for the duration of the trial, which is 25 weeks post
randomization. The primary outcome will be the percent of patients successfully transitioned off buprenorphine
and abstinent from any opioids at the 25-week trial endpoint. Secondary outcomes will include measures of
opioid withdrawal, mood, anxiety and sleep problems, abstinence from other substances, time to relapse or
dropout, and adverse effects. We hypothesize that more patients will successfully discontinue buprenorphine in
the group that received XR-NTX. This proposed exploratory trial will be able to inform the design of future
research and clinical work. A positive signal that transition from maintenance buprenorphine to XR-NTX is
feasible and prevents relapse would encourage a larger trial to replicate and perhaps extend to multiple
community based treatment settings. A feasible, well-tolerated, and effective method of helping patients
wishing to discontinue treatment with BUP has the potential to expand the population of opioid-dependent
individuals benefitting from treatment.
阿片类药物使用障碍(OUD)患者人数继续上升,超过250万人
受影响,沿着大量的发病率和死亡率。有几种有效的药物可用于治疗
丁丙诺啡成为社区使用的主要药物。丁丙诺啡有效
对于大约50- 70%的患者,治疗持续时间越长,效果越好。
然而,长期阿片类药物维持的前景对一些患者来说是不可接受的,他们最终
要求停止治疗或自行停止治疗。由于许多患者治疗反应良好,
希望停止药物治疗,需要收集有关最佳策略的证据
阿片受体拮抗剂纳洛酮被批准用于预防戒毒后的复吸
阿片类药物。纳洛酮可以作为一线治疗开始后,停止非法阿片类药物,
也可用作希望停止丁丙诺啡维持治疗并希望
我们提出了一个开放的随机门诊试验,以评估其可行性,
快速停用BUP,随后使用长效纳洛酮(XR-10)进行短期治疗的疗效
NTX),并将其与BUP逐渐锥度的标准方法进行比较。
成功完成至少6个月丁丙诺啡治疗的OUD患者(N=55)
并且不希望继续参加长期丁丙诺啡维持治疗计划的患者将被招募。
包括在研究诊所使用丁丙诺啡4- 108 mg进行为期4周的稳定治疗,以确保患者
稳定、依从性好,不含非法阿片类药物。符合上述标准的受试者将被随机分组,
1:1至:1)丁丙诺啡停药,门诊患者过渡至XR-NTX,每月注射3次,或2)
丁丙诺啡停药使用逐渐的,5- 15周长的锥度。在两组中,参与者将接受
每周一次复发预防治疗,并将在试验期间(25周后)进行监测
主要结果将是成功脱离丁丙诺啡的患者百分比。
并在25周的试验终点时戒断任何阿片类药物。次要结局将包括以下指标:
阿片类药物戒断,情绪,焦虑和睡眠问题,其他物质的戒断,复发时间或
我们假设,更多的患者将成功地停止丁丙诺啡,
这项拟议的探索性试验将能够为未来的设计提供信息。
研究和临床工作。从维持丁丙诺啡过渡到XR-β NTX的积极信号是
可行并防止复发将鼓励更大规模的试验复制,并可能扩展到多个
一种可行的、耐受性良好的、有效的帮助患者的方法
希望停止BUP治疗有可能扩大阿片类药物依赖人群,
从治疗中受益的人。
