Drug repositioning refers to the discovery of alternative uses for drugs--uses that are different from that for which the drugs were originally intended. One challenge in this effort lies in choosing the indication for which a drug of interest could be prospectively tested. We systematically evaluated a drug treatment-based view of diseases in order to address this challenge. Suggestions for novel drug uses were generated using a "guilt by association" approach. When compared with a control group of drug uses, the suggested novel drug uses generated by this approach were significantly enriched with respect to previous and ongoing clinical trials.
药物重新定位是指发现药物的其他用途——这些用途与药物最初的预期用途不同。这项工作面临的一个挑战在于选择可以对感兴趣的药物进行前瞻性测试的适应症。为了应对这一挑战,我们系统地评估了基于药物治疗的疾病观点。使用“关联有罪”方法生成了新药用途的建议。与药物用途对照组相比,通过这种方法生成的建议新药用途在先前和正在进行的临床试验方面显著富集。
