Case Summary

​A general practitioner complained about the promotion of Pradaxa (dabigatran) by Boehringer Ingelheim on a third party website.

Pradaxa (75mg and 110mg) was indicated for primary prevention of venous thromboembolic events in adults who had undergone elective total hip or total knee replacement surgery. Pradaxa (110mg and 150mg) was indicated for the prevention of stroke and systemic embolism in certain adult patients.

The detailed response from Boehringer Ingelheim is given below.

The complainant noted that a clinical paper summary, 'Dabigatran versus warfarin in patients with atrial fibrillation', provided on the website, referred only to the relative risk in relation to the key efficacy outcomes for dabigatran 150mg/110mg vs warfarin. A breach of the Code was alleged.

The complainant further noted that the clinical summary provided hyperlinks to the reprints of the two papers by Connolly et al (2009 and 2010) that it was based upon. These reprints could be downloaded and printed; the complainant alleged that this promotional facility necessitated the provision of prescribing information and its omission was in breach of the Code.

The Panel noted that the supplementary information to the Code stated, inter alia, that relative risk should never be referred to without also referring to the absolute risk. Absolute risk could be referred to in isolation.

The Panel noted that a table of data in the clinical paper summary, inter alia, referred to the relative risk stroke or systemic embolism according to treatment group. The absolute rates were also stated thus the Panel ruled no breach of the Code.

The Panel noted that the page in question provided a prominent and direct link to the prescribing information. In the Panel's view this was the first part of the material. The hyperlinked publications were part of the same material and in that regard did not also need to include links to the prescribing information. The Panel considered that prescribing information had been provided as required. No breach of the Code was ruled.

The Panel considered that by providing hyperlinks to the two Connolly et al papers, Boehringer Ingelheim had, in effect, invited readers to access the publications. This was a solicited request not an unsolicited request as alleged and therefore no breach was ruled.

The complainant noted that on another page headlined Pradaxa for use in stroke prevention in atrial fibrillation as were the specifics of the licensed indication. The reader was not informed that this indication was restricted only to Pradaxa 150mg and 110mg and not 75mg which was also available but for a different indication. The complainant alleged that this was misleading by omission.

The complainant noted that again this page facilitated access to reprints and prescribing information had been omitted.

The Panel noted that the licensed dose for Pradaxa in the prevention of stroke and systemic embolism in patients with atrial fibrillation was 150mg twice daily reduced to 110mg twice daily in certain patients. Pradaxa 75mg was not licensed for this indication but could be used in the primary prevention of venous thrombotic events in elective total hip or knee replacement surgery. The Panel noted that the page in question did not refer to any dose of Pradaxa but, as in the above, provided a link to the prescribing information on a red band running across the top of the page. The Panel considered that reference to the 75mg dose on this page was not required, given that it related only to the use of Pradaxa in the prevention of stoke and atrial fibrillation. No breach of the Code was ruled.

The Panel noted that a subsection of the page at issue was headed 'Clinical paper summaries*' and below this were links to these summaries. The asterisk referred to a footnote which read 'Promotional information by Boehringer Ingelheim'. Clicking on the links opened up the clinical paper summaries from which the reader could click to access, inter alia, the prescribing information. The Panel noted, therefore, that the prescribing information was accessible not only from the first page but also from the hyperlinked pages. The requirement to provide prescribing information had been met and no breach of the Code was ruled.

The Panel noted its comments above with regard to the provision of solicited and unsolicited reprints and considered that they also applied here. No breach of the Code was ruled.
