Project 2: Near-Infrared Targeted Tracers for Intraoperative Identification of NSCLC

项目摘要 我们的目标是开发一种针对肺癌的荧光引导成像解决方案。每年，肺癌 是美国（> 16万人）和世界（140万人）癌症相关死亡的最大原因 死亡）。本项目的主要策略是开发、表征和测试四种组合 靶向近红外造影剂，将用于人类，以改善患者的程序 患上了肺癌很明显，在癌症手术中使用荧光靶向药物可以突出 癌细胞，因此有几个小组正在测试分子探针。我们的研究将 特别关注肺癌。肺癌是一种异质性很强的肿瘤， 可能导致这种疾病的有害物质。拟议的工作将优化四种不同类型的 用于平移术中成像临床试验的组合或混合造影剂。的 第一混合剂由叶酸和与NIR染料缀合的GCPII组成。这两个对比 药物功能齐全，正在进行人体试验。然而，在一起，他们仍然错过了一个重要的 肺癌患者的比例。因此，我们将集中精力在两个更多的代理，CAIX FAP，在这份提案中。该目标的目标是整合准备用于临床的NIR示踪剂 使用.我们将在宠物犬中使用小鼠模型和自发性肺癌模型。 这四种药物的整合需要研究敏感性和特异性的变化。它将 还需要检查这些试剂的时间和这些示踪剂的相互作用。如果这杯鸡尾酒 如果成功，它将为美国头号癌症杀手提供完整的解决方案。

Project Summary Our goal is to develop a fluorescence guided imaging solution to lung cancer. Each year, lung cancer is the biggest cause of cancer related deaths in the US (>160,000 people) and the world (1.4 million fatalities). The primary strategy in this Project is to develop, characterize and test a combination of four targeted near-infrared contrast agents that will be used in humans to improve procedures for patients with lung cancer. It is clear that using fluorescent targeted agents during cancer surgery can highlight cancer cells for clinicians, thus several groups are testing molecular probes. Our research will specifically focus on lung cancer. Lung cancer is a very heterogeneous tumor due to the wide range of offending agents that can cause this disease. The proposed work will optimize four distinct types of contrast agents in a combination or cocktail for a translational intraoperative imaging clinical trials. The first cocktail agents are composed of folate and GCPII conjugated to a NIR dye. These two contrast agents are fully functional and are in human trial. However, together, they still miss a significant proportion of patients with lung cancer. Thus, we will be focusing our efforts on two more agents, CAIX and FAP, in this proposal. The goal of this Aim is to integrate the NIR tracers that are ready for clinical use. We will be utilizing both murine models and spontaneous lung cancer models in pet canines. Integration of these four agents will require studying the changes in sensitivity and specificity. It will also require examining the timing of these agents and the interactions of these tracers. If this cocktail is successful, it will provide a complete solution for the number one cancer killer in the United States.
