美国食品和药物管理局(FDA)周四发布了38种仿制药的生物等效性试验,为仿制药企业为获得批准而提交的简化新药申请(ANDA)提出具体建议。 这个列表的目的是列出通过什么样的试验来开发仿制药,虽然其中的一些抗肿瘤用药,有的还没有失去专利保护,而有的则在最近获得批准,比如,辉瑞公司的治疗乳腺癌新药Ibrance(palbociclib),卫材的甲状腺癌药物Lenvima(lenvatinib甲磺酸)和诺华的基底细胞癌的治疗Odomzo(sonidegib磷酸盐)。 ' q: S% X* f7 O+ R; D

[size=0.875]The US Food and Drug Administration (FDA) has announcedthe release of newdocuments meant to make it easier for generic manufacturers to introducecompetition to 38 existing drug products, including popular new drugs likeStendra, Belviq, Kalydeco and Brilinta. [size=0.875]The documents, known as bioequivalencerecommendations, specifically apply to the Abbreviated New Drug Application(ANDA) process—the process by which generic drugs are approved. [size=0.875]Generic drugs, unlike new drugs, may beapproved by FDA by showing that they are (among other things) bioequivalent tothe drug they intend to reference. Bioequivalence can be shown in relativelysmall trials involving human subjects, which permits a company to avoid muchlarger—and much more expensive—full clinical trials required of new drugsubstances. [size=0.875]The bioequivalence guidance documents releasedby FDA last week explain how each generic drug company can test its products toensure they pass FDA muster. Each document contains a list of recommendedstudies (typically at least two), the characteristics of each study, thestandard for bioequivalence that must be met by each generic product andpotential waivers a generic company may apply for. [size=0.875]The documents are, in effect, a roadmap forregulatory approval for generic drug companies. The publication of abioequivalence document does not, however, indicate that FDA will approve ageneric drug product immediately. Patent and marketing exclusivity protections maystill be in effect, which can preclude FDA approval or market access.
