Objectives: To investigate the practice of post-marketing studies in Germany during a three year period and to evaluate whether these trials meet the aims specified in the German Medicinal Products Act. Design: Survey of notifications submitted to German regulatory agencies before post-marketing studies were carried out, 2008-10. Setting: Notifications obtained through freedom of information requests to the three authorities responsible for registering post-marketing studies in Germany. Main outcome measures: Descriptive statistics of post-marketing studies, including the products under study, intended number of patients, intended number of participating physicians, proposed remunerations, study plan and protocol, and availability of associated scientific publications and reports on adverse drug reactions. Results: Information was obtained from 558 studies, with a median of 600 (mean 2331, range 2-75 000) patients and 63 (270, 0-7000) participating physicians per study. The median remuneration to physicians per patient was €200 (€441, €0-€7280) (£170, £0-£6200; $215, $0-$7820), with a total remuneration cost of more than €217m for 558 studies registered over the three year period. The median remuneration per participating physician per study was €2000 (mean €19 424), ranging from €0 to €2 080 000. There was a broad range of drugs and non-drug products, of which only a third represented recently approved drugs. In many notifications, data, information, and results were, by contract, strictly confidential and the sole property of the respective sponsor. No single adverse drug reaction report could be identified from any of the 558 post-marketing studies. Less than 1% of studies could be verified as published in scientific journals. Conclusions: Post-marketing studies are not improving drug safety surveillance. Sample sizes are generally too small to allow the detection of rare adverse drug reactions, and many participating physicians are strictly obliged to maintain confidentiality towards the sponsor. High remuneration and strict confidentiality clauses in these studies could influence the physicians’ reporting behaviours of adverse drug reactions.

As the EMA’s recommendation to suspend HES solutions from the market heads to the European Commission for a final decision, scientists who were asked to provide independent advice say that they were completely ignored

Objectives: To evaluate the degree to which health care professionals and patients receive consistent messages regarding the possible harms of statins. Design: Cross-sectional study of prescribing information (PI), patient package inserts (PPIs), and pharmacy leaflets for 8 statins approved by the U.S. Food and Drug Adminstration. Setting: Not applicable. Participants: Not applicable. Main Outcome Measures: All passages describing 7 adverse events (diarrhea, arthralgia, dyspepsia, confusion, memory loss, rhabdomyolysis, and kidney failure) were extracted from PIs, PPIs, and pharmacy leaflets. For each type of information source and adverse event (drug-harm pair), 2 reviewers independently judged passages as indicating either a confirmed, unconfirmed, or mixed causal relationship between statin and adverse event (drug-harm pair). Disagreements were resolved through consensus, and the consistency between information sources was calculated. Results: PI and PPI consistently conveyed the relationship between a given statin and given adverse event (either both “confirmed” or both “unconfirmed”) in 12 of 17 evaluable drug-harm pairs. PPIs and pharmacy leaflets were consistent in 10 of 10 evaluable drug-harm pairs. PIs indicated a confirmed, causal relationship in 15 drug-harm pairs that were not mentioned in pharmacy leaflets. Likewise, PPIs indicated a confirmed, causal relationship in 7 drug-harm pairs that were not listed in pharmacy leaflets. Conclusion: Despite the widespread use of statins, we discovered considerable ambiguity in language used to describe the evidence concerning their possible harms and variable consistency between PIs, PPIs, and pharmacy leaflets. Further study is needed to understand the reason why pharmacy leaflets did not list, in 15 cases, adverse events that PIs indicated were causally related to the statin.
