Provisional Combined Response Index For Patients With Diffuse Systemic Sclerosis

描述（由申请人提供）：系统性硬化症硬皮病（SSc）可与高发病率和死亡率相关。该疾病的复杂性和异质性要求一个综合反应指数，将捕获不同的器官受累和患者报告的结果。迫切需要SSc-联合反应指数（SSc- cri）来促进药物开发，并允许SSc临床试验之间的比较，就像类风湿关节炎的类似指数一样。我们汇集了一组国际专家，他们在不同关节炎的临床试验设计和反应标准的制定方面具有专业知识。加州大学洛杉矶分校临床协调中心成功地协调了最近结束的美国国立卫生研究院资助的SSc临床试验。我们在开发SSc-CRI方面迈出了第一步，通过进行结构化的德尔菲练习来开发用于临床试验的临时核心项目集。德尔菲练习确定了11个与弥漫性SSc临床试验相关的域。我们的长期目标是改进方法可靠的SSc临床试验，并增加对SSc药物开发的兴趣。本申请旨在开发一种SSc- cri，作为弥漫性SSc临床试验的结果测量指标。我们的中心假设是，弥漫性SSc患者的一组核心变量可用于开发具有稳健测试特征的SSc- cri公式。我们三年计划的具体目标是：对200名弥漫性SSc患者进行前瞻性纵向观察性临床研究，以最近完成的德尔菲练习为基础，为SSc- cri定义一套可靠、有效和有效的SSc措施。具体目标2。采用前瞻性、数据驱动、共识构建技术，为弥漫性SSc开发和定量评估SSc- cri的候选定义。本申请中提出的研究具有重要意义，因为它有望为弥漫性SSc提供单一SSc- cri，从而为药物开发提供动力，并改善临床试验中治疗剂疗效的评估。外行语言：我们建议为弥漫性硬皮病的临床试验制定一个反应标准，以促进药物开发，并有望导致有效的硬皮病治疗。

DESCRIPTION (provided by applicant): Systemic sclerosis Scleroderma, (SSc) can be associated with a high morbidity and mortality. The complexity and heterogeneity of the disease mandates a composite response index that will capture different organ involvement and patient-reported outcomes. There is a critical need for an SSc-combined response index (SSc-CRI) to facilitate drug development and to allow comparison among clinical trials in SSc, as a similar index did in rheumatoid arthritis. We have assembled a group of international experts who have expertise in clinical trial design and development of response criteria in different arthritides. UCLA Clinical Coordinating Center has successfully coordinated recently concluded NIH-funded SSc clinical trials. We took the first step in the developing an SSc-CRI by conducting a structured Delphi exercise to develop a provisional core set of items for clinical trials. The Delphi exercise identified 11 domains relevant to diffuse SSc clinical trials. Our long-term goals are to improve methodologically sound SSc clinical trials and increase interest in drug development for SSc. This application aims to develop an SSc-CRI to be used as an outcome measure in diffuse SSc clinical trials. Our central hypothesis is that a core set of variables for patients with diffuse SSc can be used to develop a formula for an SSc-CRI with robust test characteristics. Our Specific Aims for the 3-year proposal are: Specific Aim 1. Perform a prospective longitudinal observational clinical study in 200 patients with diffuse SSc to define a reliable, valid and responsive set of SSc measures for an SSc-CRI, based on a recently completed Delphi exercise. Specific Aim 2. Employ a prospective, data-driven, consensus building techniques to develop and quantitatively evaluate candidate definitions for an SSc-CRI for diffuse SSc. The research proposed in this application is significant because it is expected to provide a single SSc-CRI for diffuse SSc, thereby providing an impetus for drug development and improved assessment of efficacy of therapeutic agents in clinical trials. Lay Language: We propose to develop a response criteria for clinical trials in diffuse scleroderma that can facilitate drug development and hopefully, can lead to effective treatments for scleroderma.
