Drug development is being continuously scrutinised for its lack of productivity. Novel drug development is associated with high costs, high failure rates and lengthy development process. These downfalls combined with a huge demand in blood cancer for new therapeutic treatments have led many to consider the method of drug repurposing. Finding new therapeutic indications for already established drug substances is known as redirecting, repositioning, reprofiling, or repurposing of drugs. Off-patent and on-patent drugs can be screened for additional targets and new indications thus bringing them to clinical trials at a faster pace. This approach offers smaller research groups, such as those that are academic based, into the drug development industry. Drug repurposing can make use of previously published data concerning dosage, toxicology and mechanism of activity.
药物研发因其缺乏生产力而不断受到审视。新型药物研发成本高昂、失败率高且研发过程漫长。这些不利因素,再加上血癌对新治疗方法的巨大需求,使得许多人开始考虑药物重新利用的方法。为已获批的药物寻找新的治疗适应症,这一过程被称为药物的重新定向、重新定位、重新剖析或重新利用。可以对专利过期和仍在专利保护期内的药物进行筛选,以寻找额外的靶点和新的适应症,从而更快地将它们推进到临床试验阶段。这种方法为规模较小的研究团队,比如那些以学术为基础的团队,打开了进入药物研发行业的大门。药物重新利用可以利用先前公布的有关剂量、毒理学和活性机制的数据。
