Pharmaceutical company perspectives on current safety risk communications in Japan.

ABSTRACT: In 1987, a group infection of hepatitis in patients receiving a contaminated fibrinogen product was first reported to the Japanese regulatory agency. Eventually, this serious drug incident involved more than 10,000 cases of infection. In response, the Government of Japan established a responding inspection committee in 2008 to make recommendations for the restructuring of drug regulatory administration. The final report was issued in 2010. One agenda item of this restructuring was the improvement of drug-related safety risk communications. Our research group on drug safety risk communications, which is funded by the Government of Japan, surveyed pharmaceutical companies regarding their perspective on current risk communications. The survey was conducted using an anonymous questionnaire developed for this study which included the three operational domains of targets, contents, and measures of drug risk communication. Fifty-two of the 74 member companies of the Post-marketing Surveillance Subcommittee of the Japan Pharmaceutical Manufacturer's Association participated, and this response rate of more than 70% was considered sufficient to ensure the external validity of the survey results. Results showed that the most highly prioritized aspect of risk messaging was the strength of evidence, and that outcome evaluation of risk communication gained recognition. Further, while physicians and pharmacists were the most prioritized communication targets, pharmacovigilance departments devoted the most resources to regulators, at more than 30%. The Internet was recognized as a useful public source of risk information, whereas Drug Guides for Patients delivered on the web were considered under-recognized. Further discussion of these results with the aim of enhancing the restructuring of the Japanese drug regulatory administration system are warranted.

Project description:ImportanceClinical practice guidelines (CPGs) are important in advancing the quality of medical care. Financial relationships between physicians and pharmaceutical companies may influence clinical practice. In accordance with the Japan Pharmaceutical Manufacturers Association guidelines for transparency, pharmaceutical company payments to physicians have been disclosed since 2013. The distribution of pharmaceutical company payments among CPG authors in Japan has not been studied.ObjectivesTo determine the characteristics and distribution of payments made by pharmaceutical companies to authors of oncologic CPGs in Japan and to assess the transparency of policies associated with conflict of interest (COI) disclosures in CPGs.Design, setting, and participantsThis retrospective cross-sectional study of 326 authors from 6 prominent oncologic CPGs from Japan included annual payment data for 2016 from 78 pharmaceutical companies during varying times from January 1, 2016, through September 30, 2017.Main outcomes and measuresAmount and proportion of payments made by pharmaceutical companies to the authors; amount and proportion of payments made to the authors of each guideline; and information on policies for disclosing COIs in CPGs (Japanese yen were converted to US dollars based on the February 20, 2019 exchange rate of 110 yen per 1 US dollar).ResultsOf 326 eligible authors, 255 (78.2%) received payments from pharmaceutical companies in 2016. The total number of payments was 3947, and the total amount was $3 444 193 (¥378 861 220), including $2 696 777 for speaking, $181 944 for writing, $554 381 for consulting, and $11 091 for unclear fees. The median payment amount was $3233 (interquartile range [IQR], $506-$10 873), and the mean (SD) payment amount was $10 565 ($20 059); 84 authors (25.8%) received more than $10 000. The largest proportions of CPG authors receiving at least 1 payment were those for gastric carcinoma (92%) and colorectal carcinoma (92%). The median payment was highest for authors of colorectal carcinoma guidelines ($7781; IQR, $2506-$18 633), whereas it was lowest for authors of pancreatic carcinoma guidelines ($2207; IQR, $304-$9240). Only breast carcinoma CPGs published the authors' individual COI disclosure in an identifiable matter; guidelines for lung, colorectal, pancreatic, and hepatocellular carcinomas disclosed the financial relationships between the authors and companies anonymously; and the gastric carcinoma CPGs did not have a COI disclosure section.Conclusions and relevanceMost oncologic CPG authors received payments from pharmaceutical companies, and COI disclosure methods appeared to be insufficient. Given the possibility of bias in guideline content if authors have any financial relationships with pharmaceutical companies, CPGs from Japan may require improved transparency.

Project description:ImportanceThe pharmaceutical industry has made substantial investments in developing processes for sharing individual-participant data (IPD) from clinical trials. However, the utility and completeness of shared IPD and supporting documents must be evaluated to ensure the potential for scientific advancements from the data sharing ecosystem can be realized.ObjectiveTo assess the utility and completeness of IPD and supporting documents provided from industry-sponsored clinical trials.Design, setting, and participantsFrom February 9, 2022, to February 9, 2023, 91 of 203 clinical trials supporting US Food and Drug Administration registrations of anticancer medicines for the treatment of solid tumors from the past decade were confirmed as eligible for IPD request. This quality improvement study performed a retrospective audit of the utility and completeness of the IPD and supporting documents provided from the 91 clinical trials for a planned meta-analysis.ExposuresRequest for IPD from 91 clinical oncology trials indicated as eligible for the request.Main outcomes and measuresThe utility and completeness of the IPD and supporting documents provided.ResultsThe IPD packages were obtained from 70 of 91 requested clinical trials (77%). The median time to data provision was 123 (range, 117-352) days. Redactions were observed in 18 of the acquired IPD packages (26%) for outcome data, 11 (16%) for assessment variables, and 19 (27%) for adjustment data. Additionally, 20 IPD packages (29%) lacked a clinical study report, 4 (6%) had incomplete or missing data dictionaries, and 20 (29%) were missing anonymization or redaction description files. Access to IPD from 21 eligible trials (23%) was not granted.Conclusions and relevanceIn this quality improvement study, there was substantial variability within the provided IPD packages regarding the completeness of key data variables and supporting documents. To improve the data sharing ecosystem, key areas for enhancement include (1) ensuring that clinical trials are eligible for IPD sharing, (2) making eligible IPD transparently accessible, and (3) ensuring that IPD packages meet a standard of utility and completeness.
