Case Summary

Roche complained about the promotion of Tykerb (lapatinib) by GlaxoSmithKline. Roche noted that a pre-licence advertisement for lapatinib (‘Coming soon … Tykerb’) was published in the January 2007 issue of ‘The Oncologist’, including its UK circulation. GlaxoSmithKline claimed that this was an ‘inadvertent error’ and attributed to its US colleagues placing the advertisement without its knowledge in the UK. Nevertheless, the impact was made.

The Panel noted that supplementary information to the Code stated that advertisements published in professional journals came within the scope of the Code if they were produced in the UK and/or intended for a UK audience. International journals that were produced in English in the UK were subject to the Code even if only a small proportion of their circulation was to a UK audience.

The Oncologist was published by AlphaMed Press, Carolina, USA, and AlphaMed Europe based in Northern Ireland. The Panel noted GlaxoSmithKline’s submission that when commissioning the advertisement, the US company was unaware of any non US print runs for The Oncologist and did not specify any particular run for the advertisement. Further the journal had no separate European run. GlaxoSmithKline thus submitted that the issue of the journal in question was obtained in the US. The Panel noted that had the advertisement appeared in a separate run of the journal that had been produced in the UK or had otherwise been intended for a UK audience it would have come within the scope of the Code. However, on the basis of GlaxoSmithKline’s submission the Panel decided that the run of The Oncologist at issue did not satisfy the criteria and thus the matter was outside the scope of the Code. No breach was ruled.

Roche’s ongoing media monitoring had shown high levels of Tykerb/lapatinib coverage. Roche had had correspondence with GlaxoSmithKline on this matter, specifically relating to an article in the Sunday Express on 17 September in which a GlaxoSmithKline source was quoted as saying that the medicine would achieve better results than Herceptin. Although Roche received assurances from

GlaxoSmithKline that this had not arisen from GlaxoSmithKline briefings, it was clearly attributed to GlaxoSmithKline. Tykerb was unlicensed in the UK and no head-to-head comparative data existed against Herceptin. Should this statement have come via a GlaxoSmithKline supported agency, GlaxoSmithKline was still responsible.

Evidence of an engineered campaign of premarketing was supported by the consistency of wording of claims that were appearing in the media, including regular comparisons with Herceptin. More specifically, there had been several mentions that lapatinib might be ‘better than Herceptin’, that lapatinib might be effective in ‘Herceptin resistant’ patients, that lapatinib might be effective in brain metastases, and that lapatinib might have less cardiotoxicity than Herceptin. There was no evidence to support the above claims and whilst Roche accepted that there might be an element of misunderstanding amongst the media, the consistency with which such messages had been conveyed in the media strongly suggested that there must be some origin for these unfounded claims. It seemed a totally improbable coincidence that this could originate from a source other than GlaxoSmithKline. Totally unfounded statements over safety were of particular concern and should be viewed as a breach of Clause 2.

The Panel noted that the article in question in the Sunday Express referred to the superiority of lapatinib over Herceptin. The article stated that ‘GlaxoSmithKline claims the drug will achieve better results than Herceptin, a rival treatment …’. Complaints about articles in the media were judged on the information provided by the company to the journalist. The Panel noted GlaxoSmithKline’s submission that neither it nor its agency had spoken to the journalist in question. GlaxoSmithKline had however issued a corporate press release about the Tykerb US filing and thereafter answered a question from a different journalist at the Sunday Express about when the filing was due to take place. GlaxoSmithKline had surmised that this second journalist had relayed this information to the author of the article and that it was possible that the Sunday Express article may have been prompted by the embargoed press release.

The press release was headed ‘GlaxoSmithKline seeks US approval for Tykerb (lapatinib ditosylate) for the treatment of advanced breast cancer’.  The date of issue was Monday, 18 September. The press release described the product’s proposed US licensed indication – in combination with Xeloda for the treatment of advanced or metastatic HER2 (ErbB2) positive breast cancer in women who had received prior therapy, including Herceptin. The compound had been granted fast track status by the FDA in this patient population. The press release made it clear that Tykerb was an investigational medicine and had not been approved for marketing by any regulatory body. The trial on which the application was based, was described and referenced to Data on file, King of Prussia. It was noted that an interim analysis showed that relevant women in whom the disease progressed following treatment with Herceptin and other cancer therapies when transferred either to Tykerb and Xeloda or Xeloda alone, the combination of Tykerb and Xeloda nearly doubled median time to progression (36.7 weeks [8.5 months] in the combination arm vs 19.1 weeks [4.4 months] versus Xeloda alone, p= 0.00008).  The press release also stated that in March 2006 an independent data monitoring committee recommended that enrolment ceased based on the early success of the trial. The study met its primary endpoint of time to disease progression and exceeded the predetermined stopping criteria. Enrolment stopped in April 2006. The press release supplied by GlaxoSmithKline did not mention an embargo.

The Panel did not consider that the press release supplied to the Sunday Express implied that Tykerb would achieve better results than Herceptin, nor that head-to-head comparative data existed as alleged. References to Herceptin were within the context of the proposed licensed indication in the US which was clearly stated in the press release. No breach of the Code ruled.

In relation to the allegation about a premarketing campaign involving comparative claims with Herceptin the Panel noted GlaxoSmithKline’s submission that any conversations with journalists had been restricted to messages in the approved press releases. The evidential burden was on Roche to establish, on the balance of probabilities that GlaxoSmithKline had supplied material to the media which was misleading or otherwise in breach of the Code as alleged. The Panel noted the series of published articles provided by Roche and a summary of the coverage. Roche cited that Tykerb might be ‘better than Herceptin’, ‘effective in Herceptin resistant patients’, ‘effective in brain metastases’ and ‘have less cardiotoxicity than Herceptin’. Nonetheless, the Panel also noted that none of the press releases issued by GlaxoSmithKline or its corporate office featured the comparative claims referred to by Roche.

GlaxoSmithKline had provided copies of press releases dated from May 2006 to December 2006. Two were clearly marked for medical press only, one was a London Stock Exchange announcement. Eight discussed phase III data, one noted its imminent publication. The licensing status was made clear. The Panel was concerned that the intended audience was not always clear on the face of the press release. The Panel was also concerned that the heading to a press release dated 28 December described the phase III data as ‘Landmark’ data and referred to it changing the ‘treatment paradigm’.  Other press releases described the phase III trial more modestly as ‘positive new data’.  However, on the evidence before it the Panel did not consider that the press materials overall amounted to promotion of a medicine prior to the grant of marketing authorization or were otherwise in breach of the Code as alleged. No breach of the Code was ruled.
