项目摘要

PROJECT SUMMARY / ABSTRACT Knee osteoarthritis is a very common and debilitating condition, affecting >14 million Americans. Many people with knee osteoarthritis require total knee arthroplasty (TKA) to treat pain and improve function, and opioids remain the primary modality for treatment of pain after TKA. However, opioids carry significant side effects, with ~80% of surgical patients reporting at least one moderate or severe side effect (e.g. nausea, dizziness, constipation). Moreover, perioperative opioid exposure is associated with patients becoming dependent on opioids long after surgical recovery, and new chronic opioid dependence is subsequently associated with increased healthcare costs, the development of opioid use disorder (addiction), overdose, and death. Hence, research into opioid alternatives for postoperative pain is of critical importance. Cannabinoids, including cannabidiol (CBD), are one class of potential opioid-sparing pain medications. While CBD is used by an estimated 14% of the general public, most frequently for chronic pain and related symptoms (including as an opioid substitute), rigorous clinical research on CBD is limited. CBD shows great promise, as it is non- intoxicating, and reduces pain, anxiety and inflammation in animal studies. Previous research has found that CBD reduced opioid craving and anxiety, which further suggests it may decrease opioid use after surgery. It is also well tolerated across numerous medical conditions. Moreover, CBD (Epidiolex), the study drug we will use, is approved by the Food and Drug Administration for treating some seizure disorders, and it is not subject to the same regulatory restrictions as Δ -9-tetrahydrocannabinol (THC). In this study, we will recruit 380 patients undergoing primary total knee arthroplasty (TKA) from two large health systems. In this multi-site, 2x2 factorial, double-blind, randomized controlled trial, participants will receive one of four combinations of placebo or CBD (300 mg/day) for one week prior to surgery together with CBD or placebo for 4 weeks following surgery. Our primary outcome will be post-operative opioid consumption in the 4-week period following surgery. The study design will also allow us to investigate and untangle CBD's pre- and post-surgical effects, including reduction of anxiety, sleep disturbance and inflammation. We will also conduct detailed investigations of the side effects and adverse events, as well as pharmacokinetics of CBD throughout the treatment course. The successful completion of this study will give much needed evidence for the role of CBD as an opioid-sparing medication for pain after surgery. Given that there are more than 50 million surgeries each year in the United States, these findings could have much broader implications beyond TKA and would motivate important new lines of research into the role of CBD.
项目摘要/摘要 膝骨性关节炎是一种非常常见的令人虚弱的疾病,影响着1400万美国人。很多人 患有膝骨性关节炎的患者需要全膝关节置换术(TKA)来治疗疼痛和改善功能,阿片类药物 仍然是治疗全膝关节置换术后疼痛的主要方法。然而,阿片类药物有显著的副作用, 约80%的外科患者报告至少有一种中度或严重的副作用(例如恶心、头晕、 便秘)。此外,围手术期阿片类药物暴露与患者对阿片类药物的依赖有关 阿片类药物在手术恢复后很久,新的慢性阿片类药物依赖随后与 医疗费用增加,阿片类药物使用障碍(成瘾),过量服药和死亡。因此, 研究用于术后疼痛的阿片类药物替代品至关重要。大麻素, 包括 大麻二醇(CBD)是一类潜在的非阿片类止痛药。而CBD由一个 估计有14%的普通公众,最常见的是慢性疼痛和相关症状(包括 阿片类替代品),对CBD的严格临床研究有限。CBD显示出巨大的前景,因为它是非 令人陶醉,并在动物研究中减少疼痛、焦虑和炎症。此前的研究发现, CBD减少了阿片类药物的渴望和焦虑,这进一步表明它可能减少手术后阿片类药物的使用。它是 对多种疾病也有很好的耐受性。此外,我们将研究的药物CBD(Epidiolex) 用途,由食品和药物管理局批准用于治疗某些癫痫发作障碍,不受 遵守相同的监管限制 Δ -9-四氢大麻酚(THC)。在这项研究中,我们将招募380名患者 在两个大型医疗系统进行初次全膝关节置换术。在这个多站点的2x2阶乘中, 双盲随机对照试验,参与者将接受安慰剂或CBD的四种组合之一 (300毫克/天),手术前一周,同时服用CBD或安慰剂,手术后4周。我们的 主要结果将是术后4周内阿片类药物的使用情况。这项研究 设计还将使我们能够调查和理清CBD手术前和手术后的影响,包括复位 焦虑、睡眠障碍和炎症。我们还将对副作用进行详细调查 在整个治疗过程中,CBD的药物动力学和不良反应。成功者 这项研究的完成将为CBD作为一种非阿片类药物的作用提供急需的证据 治疗手术后的疼痛。鉴于美国每年有超过5000万例手术,这些 研究结果可能会产生比TKA更广泛的影响,并将激励重要的新路线 研究CBD的作用。
