项目摘要

DESCRIPTION (provided by applicant): Suicide and suicide attempts cost an estimated $33 billion annually in the U.S. and immeasurable pain and suffering. Most suicidal behavior is associated with a depressive disorder, yet medication guidelines for suicidal patients are virtually nonexistent. The evidence base is severely limited because suicidal patients are excluded from most antidepressant clinical trials. Several recent studies show rapid improvement in suicidal ideation, in as little as one hour, in depressed patients after intravenous infusion of sub-anesthetic ketamine, a glutamate antagonist and commonly used anesthetic. The improvement in suicidal ideation appears to last several days, however, depression and suicidality are usually chronic, recurring conditions. We propose a rigorous clinical trial in suicidal depressed patients to test random assignment to IV infusion of ketamine or midazolam control followed by open continuation treatment with antidepressant medication plus supportive case management. The primary goal is to test ketamine's potential anti-suicidal effects versus a similarly sedative control medication not known to reduce suicidal ideation. Exploratory aims include analysis of potential biological (salivary cortisol) and neuro-cognitive correlates as well as systematic assessment of suicidal ideation and behavior during continuation treatment. Establishing a strong anti-suicidal signal for ketamine in this high-risk population would support an innovative intervention that could change clinical care for a patient population of public healt importance. Exploratory assessment of suicidal ideation and behavior during continuation treatment could help target research on strategies to sustain the benefit of ketamine.

描述（由申请人提供）：在美国，自杀和自杀未遂每年造成的损失估计为 330 亿美元，造成的痛苦和折磨难以估量。大多数自杀行为与抑郁症有关，但针对自杀患者的药物指南几乎不存在。证据基础严重有限，因为自杀患者被排除在大多数抗抑郁药物临床试验之外。最近的几项研究表明，抑郁症患者接受静脉注射后，自杀意念在短短一小时内迅速改善。输注亚麻醉氯胺酮（一种谷氨酸拮抗剂和常用麻醉剂）。自杀意念的改善似乎会持续几天，然而，抑郁和自杀倾向通常是慢性、反复出现的状况。我们建议在自杀性抑郁症患者中进行严格的临床试验，以测试随机分配氯胺酮或咪达唑仑静脉输注对照，然后使用抗抑郁药物和支持性病例管理进行开放式持续治疗。主要目标是测试氯胺酮与类似的镇静控制药物（未知是否可以减少自杀意念）相比的潜在抗自杀作用。探索性目标包括分析潜在的生物学（唾液皮质醇）和神经认知相关性作为持续治疗期间自杀意念和行为的系统评估。在这一高危人群中建立氯胺酮的强烈抗自杀信号将支持创新干预措施，从而改变对具有公共卫生重要性的患者群体的临床护理。对继续治疗期间的自杀意念和行为进行探索性评估有助于有针对性地研究维持氯胺酮益处的策略。
