Case Summary

Boehringer Ingelheim complained about Bayer Schering Pharma's promotion of its anticoagulant Xarelto (rivaroxaban). Boehringer Ingelheim supplied Pradaxa (dabigatron).

Given the dates of the activities in question the Panel decided to use the provisions of the 2006 Code using the 2008 Constitution and Procedure. The clauses at issue had not changed under the two Codes but some had been renumbered.

The detailed responses from Bayer Schering are given below.

Boehringer Ingelheim alleged that at the Irish Orthopaedic Association meeting, Belfast, in June 2008, Bayer Schering had an exhibition stand on venous thromboembolism which stated 'Great Clinical Need for New Anticoagulants…' and then described various desirable attributes. The stand was manned by sales representatives and marketing team members. Boehringer Ingelheim was concerned that having the stand would solicit questions on the availability of new anticoagulants and that questions would be answered by sales representatives, promoting the medicine prior to the receipt of the marketing authorization. The stand did not mention that the new anticoagulant Pradaxa (dabigatran) with this profile was available. Boehringer Ingelheim alleged that this was disparaging and misleading. Boehringer Ingelheim noted that Bayer Schering had distributed a leaflet entitled 'Thrombosis Adviser' and a two question quiz card on deep vein thrombosis and the characteristics of an ideal anticoagulant. The quiz offered entry into a draw to win a book voucher which Boehringer Ingelheim alleged was in breach of the Code.

The Panel noted that the material had been supplied by Bayer Schering's Irish affiliates. As the meeting took place in the UK, the UK Code applied.

The Panel noted that one of the exhibition panels at issue referred to VTE (venous thromboembolism) as a seriously underestimated killer. The second exhibition panel was headed 'Great Clinical Need for New Anticoagulants Providing: effective anticoagulation; low risk of bleeding; oral delivery; wide therapeutic window; fixed dosing; no monitoring; low risk of food and drug interactions and predictable pharmacology'. The Panel considered that the second exhibition panel, given the context in which it was used, ie a promotional exhibition space, in effect promoted Xarelto in June 2008 prior to the grant of its marketing authorization on 1 October 2008. The exhibition panel listed Xarelto's benefits; it would be clear to delegates that Bayer Schering had a commercial interest in an oral anticoagulant with the profile listed. A breach was ruled.

The Panel considered that the heading to the second exhibition panel 'Great Clinical Need for New Anticoagulants Providing:' ignored the fact that Boehringer Ingelheim's new anticoagulant (Pradaxa) was already available. The heading implied that no anticoagulant was available with the properties listed which was not so. The Panel noted Bayer Schering's submission that the unmet need referred to therapy areas other than preventing VTE following orthopaedic surgery. This was not made clear on the exhibition panel. The Panel considered that the exhibition panel was misleading and disparaging as alleged. Breaches of the Code were ruled.

The Panel noted that a leaflet distributed from the exhibition stand had asked delegates to 'Test your knowledge on VTE and enter a draw to win a book voucher .'. The supplementary information to Clause 18.2 of the 2006 Code stated 'The use of competitions, quizzes and suchlike, and the giving of prizes, are unacceptable methods of promotion'. A breach was ruled as alleged.

With regard to a supplement on rivaroxaban in the Journal of Bone and Joint Surgery (JBJS), Boehringer Ingelheim noted that the journal was available on 4 September 2008 prior to the grant of the marketing authorization for rivaroxaban.

The supplement was funded by Bayer Schering as stated in the acknowledgements of each article. However, there was no clear mention of the sponsor company at the outset.

Boehringer Ingelheim alleged that the statement 'An introduction to rivaroxaban: the first oral, once-daily, direct Factor Xa inhibitor for the prevention of venous thromboembolism' was misleading as it implied that rivaroxaban was available in September 2008 for prescription.

A statement, 'Rivaroxaban offers clinicians and their patients a novel orally active anticoagulant for extended thromboprophylaxis in the outpatient setting' was alleged to be misleading and promotion prior to the grant of the marketing authorization as 'offers' was in the present tense.

The claims 'Rivaroxaban will offer clinicians the opportunity….' and 'Importantly, unlike parenteral anticoagulants, rivaroxaban will enable an easy transition…' implied that rivaroxaban would work for all patients which was alleged to be misleading and exaggerated. In addition, Boehringer Ingelheim considered that these claims implied that rivaroxaban would definitely be available which, given that rivaroxaban was not licensed at the time of publication, was in breach of the Code.

The graph 'Efficacy of currently available options for venous thromboprophylaxis' (emphasis added) did not include dabigatran which had a marketing authorization for primary prevention of venous thromboembolism events in adults following elective total hip or knee replacement surgery and was available in the UK. Boehringer Ingelheim alleged that the graph did not reflect up-to-date evidence and was misleading.

The Panel noted that the objective was to provide the proceedings of a symposium, sponsored by Bayer Schering at an international meeting, in the form of a journal supplement. The Panel considered that it would not always be possible to achieve this and comply with the requirements of the Code.

The Panel noted that the supplement had been initiated by Bayer Schering and its agency. The co-editors and first authors were those who had taken part in the company-sponsored symposium at EFORT 2008 and although they had not been paid to write the articles in question they had all received honoraria for other work they had done for Bayer. Professional writing support and editorial assistance was funded by Bayer HealthCare AG.

The Panel considered that Bayer Schering was inextricably linked to the production of the supplement. There was no arm's length arrangement between the provision of the sponsorship and the generation of the supplement. Circulation of the supplement was not limited to those who attended the meeting as it was circulated with the JBJS. Given the company's involvement and the content of the supplement, the Panel considered that the supplement was, in effect, promotional material for Xarelto. Further, the Panel noted that the supplement was not formally peer reviewed by the JBJS. The Panel considered that the material was a paid-for insert from Bayer Schering, not a supplement from the JBJS for which its editorial board would have been responsible. The back cover of the supplement stated:

'This supplement is provided free with the British Volume of JBJS. The contents have not been selected or edited by the Journal. All questions about scientific content should be addressed to the individual authors.'

The supplement was distributed with the September issue of the JBJS. Xarelto did not receive a UK marketing authorization until 1 October 2008. The Panel noted its comments above and considered that the supplement had promoted Xarelto to UK health professionals prior to the grant of the marketing authorization. A breach was ruled as acknowledged by Bayer Schering.

The Panel did not consider that the statement 'An introduction to rivaroxaban: the first oral, once daily, direct Factor Xa inhibitor for the prevention of venous thromboembolism' implied that the product was available for prescription in September 2008 as alleged. No breach was ruled. Similarly the Panel did not consider that the claim 'Rivaroxaban offers clinicians and their patients a novel orally active anticoagulant …' was misleading through the use of the present tense. No breach was ruled. Insomuch as the claim promoted Xarelto, however, the Panel considered that its ruling of a breach above covered this aspect.

The Panel did not consider that the statement 'Rivaroxaban will offer clinicians the opportunity to use a fixed dose, unmonitored, once-daily anticoagulant, given as a single 10mg tablet, for the prevention of VTE after major orthopaedic surgery. Importantly, unlike parental anticoagulant, Rivaroxaban will enable an easy transition from hospital to outpatient thromboprophylaxis, providing an opportunity to improve further the current standard of care in this high risk patient population' implied, as alleged, that Xarelto would work for all patients. In that regard the Panel did not consider that the statement was either misleading or exaggerated. No breach was ruled. Insomuch as the statement promoted Xarelto, the Panel considered that its ruling of a breach above covered this aspect.

The graph entitled 'Efficacy of currently available options for venous thromboembolism prophylaxis' was compiled from Geerts et al (2001). The data thus pre-dated the introduction of dabigatran onto the UK market. In that regard the data was not up-to-date and was misleading. Breaches were ruled.

The front cover of the supplement did not feature a statement acknowledging Bayer Schering's involvement thus a breach was ruled.

Boehringer Ingelheim was very concerned about the activities of Bayer Schering as detailed above and alleged that the company had undertaken pre-licence promotional activities. Boehringer Ingelheim was further concerned that, despite multiple discussions between the two companies regarding the need to comply with the Code, Bayer Schering had repeatedly undertaken activities in the sensitive pre-licence period which had not been through self-regulation review and approval processes according to the requirement of the Code. Taking all these activities into account Boehringer Ingelheim alleged that Bayer Schering's actions had brought the industry into disrepute in breach of Clause 2.

The Panel considered that the arrangements within Bayer Schering showed poor control. It appeared that non UK parts of the business had little awareness of matters to be considered when conducting activities in the UK. It was the responsibility of the UK company to ensure compliance within the UK Code. A medicine had been promoted prior to the grant of its marketing authorization on more than one occasion. Taking all the circumstances into account the Panel considered that Bayer Schering had brought discredit upon and reduced confidence in the pharmaceutical industry and a breach of Clause 2 was ruled.
