The Food and Drug Administration (FDA) approved on July 23, 2010, the abbreviated new drug application (ANDA) by Sandoz Inc for a generic enoxaparin (Lovenox) as the FDA is satisfied with the active ingredient ''sameness'' and the interchangeability of Lovenox with this generic version. Regulatory authorities that consider low-molecular-weight heparins (LMWHs) as drugs approve generic LMWHs via an ANDA pathway, whereas EMEA views them as biological medicines and will therefore regulate copies of LMWHs via a biosimilar pathway because only similar copies can be manufactured. Furthermore, European Medicines Agency (EMEA) requires appropriately powered clinical trails to establish comparable efficacy and safety profiles for biosimilar and their branded LMWHs counterparts. The safety issues that have led to withdrawal of some generic LMWHs from some Asian and South American countries mandate the need for a broad consensus defining the minimum attributes copies of LMWHs required for efficacy and safety.
2010 年 7 月 23 日,美国食品和药物管理局(FDA)批准了山德士公司的依诺肝素(Lovenox)仿制药简略新药申请(ANDA),因为 FDA 对活性成分“相同性”和 Lovenox 与这种仿制药的可互换性感到满意。将低分子肝素(LMWHs)视为药物的监管机构通过 ANDA 途径批准通用 LMWHs,而 EMEA 将其视为生物药物,因此将通过生物类似药途径监管 LMWHs 的仿制药,因为只能制造类似的仿制药。此外,欧洲药品管理局(EMEA)要求进行适当的临床试验,以确定生物类似药及其品牌 LMWHs 对照品的等效性和安全性。导致一些通用 LMWHs 从一些亚洲和南美国家撤出的安全问题,需要达成广泛共识,确定 LMWHs 仿制药的最低属性,以确保疗效和安全性。
