项目摘要
SUMMARY
The importance of biomarkers in clinical practice and regulatory science is difficult to overstate. The ultimate
goal for clinical care of the future is to determine the most appropriate therapy for each patient’s unique version
of a particular disease. This concept of precision medicine has been identified as a national priority in the USA,
leading to a need for biomarkers that can provide objective and reproducible information. In addition, regulatory
science for the approval of new qualified drugs and medical technologies has an urgent need for qualified
biomarkers to report on the success or failure of these drugs and technologies. Imaging biomarkers, providing
in situ “biopsies”, have the potential to provide such specific information and, ultimately, to improve routine
clinical care and speed up development of new treatments. The overall goal of this Resource therefore is to
develop novel noninvasive MRI candidate biomarkers that can ultimately be used for: (i) personalized
assessment of patients for diagnosis, prognosis, and treatment monitoring; (ii) monitoring of the development
of new medical technologies and drugs, i.e. for better guiding of clinical trials. The significance of our proposed
developments lies in providing the fundamental design and initial testing (i.e. not clinical trials itself) of new MRI
candidate biomarkers with the potential to provide surrogate quantitative imaging endpoints that are as close
as possible to clinical endpoints. As such, this Resource will focus on designing, calibrating and standardizing
new magnetic resonance (MR) technologies to provide reliable measures across sessions, scanners, and
raters. This technology will then be disseminated for larger scale patient studies to allow clinical validation.
The MRI Resource for Physiologic, Metabolic and Anatomic Biomarkers is an interdepartmental and
interdisciplinary consortium combining facilities and expertise of the F.M. Kirby Research Center at Kennedy
Krieger Institute (KKI), the Department of Radiology at Johns Hopkins University (JHU) School of Medicine, the
Center for Imaging Science at the JHU Whiting School of Engineering, and the Department of Biostatistics at
the JHU Bloomberg School of Public Health. We propose 4 TRD projects, 3 on MR acquisition approaches and
one bringing them together with advanced multi-scale data analysis methods that include machine learning. To
assure a proper choice of technologies, we will interact closely with a group of clinical and research experts in
a push-pull relationship through collaborative projects (CPs) that focus on brain diseases, disorders, and
injuries that have a need for new quantitative MR technology to better and noninvasively assess them. These
include anemia/ischemia and related white matter hyperintensity lesions (CPs 1,5), aging, cerebrovascular
disease, and dementia (CPs 2,7,10), traumatic brain injury (CP4), glymphatic function (CP6), pain (CP8) and
addiction (CP9). As an initial testbed for our methods, we also have a group of service projects (SPs) to which
we will provide both data acquisition methods and data analysis software. Finally, we will train investigators in
their use and disseminate methods nationwide and to MRI manufacturers for even broader application.
概括
生物标志物在临床实践和监管科学中的重要性很难夸大其词。最终
对未来临床护理的目标是确定每个患者独特版本的最合适的疗法
特定疾病。这种精确医学的概念已被确定为美国的国家优先事项
导致需要提供客观和可重复信息的生物标志物。另外,调节性
批准新合格药物和医疗技术的科学迫切需要合格的
生物标志物报告这些药物和技术的成功或失败。成像生物标志物,提供
原位“活检”,有可能提供此类特定信息,并最终改善常规
临床护理和加快新疗法的发展。因此,该资源的总体目标是
开发新颖的无创MRI候选生物标志物,最终可以用于:(i)个性化
评估患者的诊断,预后和治疗监测; (ii)监视开发
新的医疗技术和药物,即更好地指导临床试验。我们提议的意义
发展在于提供新MRI的基本设计和初始测试(即不是临床试验)
候选生物标志物具有提供替代定量成像终点的潜力
尽可能到临床终点。因此,此资源将重点放在设计,校准和标准化上
新的磁共振(MR)技术可在会话,扫描仪和
评估者。然后,该技术将被传播以进行大规模的患者研究,以允许临床验证。
