目前还没有治疗骨关节炎的疾病修正药物被批准。过去临床试验失败的原因有几个,包括通常应用的基于放射评估的结构资格定义。在精确医学的背景下,为特定的治疗方法找到合适的患者将变得越来越重要。在符合条件的情况下,通过成像进行表型分层在未来将是至关重要的,仅使用放射学不能实现这一点。此外,需要确定进展更快的高风险关节,因为这些关节可能会允许更有效的DMOAD试验设计。此外,筛查时需要排除塌陷风险较高的关节。磁共振成像可能能够在这方面提供解决方案,由于技术进步和简化的图像评估,人们普遍认为磁共振成像在资格评估中的应用中的障碍正在得到解决。
Currently no disease-modifying drugs for osteoarthritis have been approved. There are several reasons for failure of clinical trials in the past, including the commonly applied definition of structural eligibility based on radiographic assessment. In the context of precision medicine it will be of increasing relevance to find the appropriate patient for a specific treatment approach. Phenotypical stratification by imaging at eligibility will be paramount in the future and cannot be achieved using radiography alone. Furthermore, joints at high risk for faster progression need to be identified, as these may allow a more efficient DMOAD trial design. In addition, joints at high risk for collapse need to be excluded at screening. MRI may be able to offer solutions in this context, and commonly perceived hurdles in the application of MRI at eligibility assessment are being addressed as a result of technological advances and simplified image assessment.
