To describe and assess the outcomes of Periodic Safety Update Report (PSUR) evaluations of biopharmaceuticals.
A cross-sectional analysis was performed of follow-up requirements of PSURs submitted for centrally approved biopharmaceuticals in the European Union between 1 July 2008 and 30 June 2010. A follow-up analysis on a subset of products that submitted multiple PSURs within the study period was also performed.
The cross-sectional analysis included 70 PSURs. Potential safety concerns occurred in 57 (83 %) of all PSURs, and 26 (37 %) concluded a need to change the Summary of Product Characteristics (SPC). In comparison to newer products, products authorized for more than 10 years contained significantly fewer potential safety concerns (60 vs. 92 %; p < 0.01) and required fewer SPC changes (15 vs. 46 %; p = 0.03). For 45 products, multiple PSURs were submitted that could be included in a follow-up analysis. For this subset of products, of the 106 newly identified safety potential safety issues, 7 (7%) resulted in requirements for label changes in the following PSUR.
PSURs facilitate communication between regulators and marketing authorization holders. Potential safety concerns occur for the majority of biopharmaceuticals and throughout their lifecycle, but for established products PSUR evaluations rarely lead to regulatory actions.
描述和评估生物制药定期安全性更新报告(PSUR)评估的结果。
对 2008 年 7 月 1 日至 2010 年 6 月 30 日期间在欧盟集中批准的生物制药提交的 PSUR 的随访要求进行了横断面分析。还对研究期间提交多次 PSUR 的产品子集进行了随访分析。
横断面分析包括 70 份 PSUR。所有 PSUR 中有 57 份(83%)出现潜在安全问题,26 份(37%)得出需要更改产品特性摘要(SPC)的结论。与较新的产品相比,授权使用超过 10 年的产品发现的潜在安全问题明显较少(60%比 92%;p<0.01),需要更改 SPC 的情况也较少(15%比 46%;p=0.03)。对于 45 种产品,提交了多次 PSUR,可以进行随访分析。对于这组产品,在 106 个新确定的潜在安全问题中,有 7 个(7%)导致在随后的 PSUR 中需要更改标签。
PSUR 促进了监管机构和上市许可持有人之间的沟通。大多数生物制药在其整个生命周期中都会出现潜在的安全问题,但对于成熟产品,PSUR 评估很少导致监管行动。
