DESCRIPTION (provided by applicant): Parkinson's disease is an inexorably progressive disorder of unknown cause in which neurons of the substantial nigra progressively degenerate resulting in ever-greater degrees of brain dopamine deficiency. While a number of treatments have been developed that improve the neurochemical deficit, no treatment has been demonstrated to ameliorate the neuronal deterioration. Such a neuroprotective effect is highly desirable because if this could be achieved, a significant delay in clinical deterioration of patients could be realized. The proposal outlined here aims to establish a Clinical Center for neuroprotective research at UT Southwestern Medical Center which will cooperate with up to 42 other such centers around the country in the development and execution of a large-scale clinical trial to test one or more potentially neuroprotective agents for Parkinson's disease. The Clinical Center for Movement Disorders at UT Southwestern Medical Center in Dallas, TX is well suited to becoming such a Clinical Center. It is the primary academic referral center for North Texas and its two staff neurologists are experienced in the design, conduct, and reporting of clinical trials in Parkinson's disease. Once the Clinical Centers are designated, a series of pilot studies will be conducted first to identify the most promising agent or agents. Subsequently, a large trial involving several thousand patients will be developed and conducted to establish whether the chosen agent is actually capable of slowing down the progression of this disease. By studying such a large number of patients under rigorously blinded and controlled conditions, it should be possible to identify even a small beneficial effect on disease progression which would nevertheless be very important, not only for the implications on retarding disease progression, but also because observing such an effect might yield insights into the underlying pathogenesis of this common and disabling disease.

描述（由申请人提供）：帕金森病是一种原因不明的不可阻挡的进行性疾病，其中实质黑质的神经元逐渐退化，导致大脑多巴胺严重缺乏。虽然已经开发出许多改善神经化学缺陷的治疗方法，但没有任何治疗方法被证明可以改善神经元退化。这种神经保护作用是非常理想的，因为如果能够实现这一点，就可以实现患者临床恶化的显着延迟。这里概述的提案旨在在 UT 西南医学中心建立一个神经保护研究临床中心，该中心将与全国多达 42 个其他此类中心合作，开发和执行大规模临床试验，以测试一种或多种潜在的神经保护作用帕金森病药物。 位于德克萨斯州达拉斯的 UT 西南医学中心的运动障碍临床中心非常适合成为这样的临床中心。它是北德克萨斯州的主要学术转诊中心，其两名神经科医生在帕金森病临床试验的设计、实施和报告方面经验丰富。一旦指定了临床中心，将首先进行一系列试点研究，以确定最有前途的药物。随后，将开发并进行一项涉及数千名患者的大型试验，以确定所选药物是否确实能够减缓这种疾病的进展。通过在严格盲法和受控条件下研究如此大量的患者，应该有可能识别出对疾病进展的哪怕很小的有益影响，尽管如此，这仍然非常重要，不仅对于延缓疾病进展的影响，而且因为观察这种效应可能有助于深入了解这种常见致残性疾病的潜在发病机制。
