Case Summary

GlaxoSmithKline complained about an advertisement for Actos (pioglitazone) placed by Takeda Pharmaceuticals Europe in Diabetologia, April 2008. GlaxoSmithKline supplied Avandia (rosiglitazone). Pioglitazone and rosiglitazone were thiazolidinediones (TZDs).

GlaxoSmithKline noted that a previous Actos advertisement, published in January 2008 by Takeda UK had been reviewed by the Medicines and Healthcare products Regulatory Agency (MHRA) and found in breach of the Medicines (Advertising) Regulations. The MHRA was concerned that claims relating to Actos and cardiovascular (CV) risks did not reflect the balance of risks and benefits for the product as stated in the summary of product characteristics (SPC). It was considered that the advertisement was misleading and would not encourage the rational use of Actos. In March 2008 the MHRA asked Takeda UK to provide a corrective statement and not use the advertisement again.

GlaxoSmithKline considered that the advertisement now at issue, although different to the one reviewed by the MHRA, was similar.

The advertisement in question contained the prominent claim 'There are no long-term cardiovascular concerns regarding the use of Actos (pioglitazone)'. However, there was no mention that Actos was contraindicated in patients with cardiac failure or a history of cardiac failure (NYHA stages I to IV) or might cause fluid retention which might exacerbate or precipitate heart failure and therefore additional monitoring of cardiovascular status might be required in some patients (ref SPC).

Given the limited and inadequate presentation of CV data GlaxoSmithKline alleged that the advertisement was not in accordance with the terms of the marketing authorization and was inconsistent with the particulars listed in the SPC; the information provided and the claims were not accurate and did not reflect the balance of risks and benefits as stated in the Actos SPC or contained in the data in their entirety, and were therefore misleading; by presenting inaccurate and misleading data on the CV profile of Actos the advertisement would not encourage the rational use of the medicine. GlaxoSmithKline was particularly concerned that the advertisement could prejudice patient safety, especially as the appropriate checks, required for some patients, were not specifically mentioned within the item.

GlaxoSmithKline considered the publication of the advertisement at issue shortly after action taken bythe MHRA was an amazing disregard for the very serious points raised by itself and the UK regulatory agency and a breach of Takeda's undertaking to the MHRA. GlaxoSmithKline therefore alleged that Takeda had brought discredit upon, and reduced confidence in, the industry in breach of Clause 2.

Diabetologia was published in English in Germany, the editor-in-chief and editorial office was in the UK and it was circulated to UK health professionals as well as to other countries. In the Panel's view promotional material in Diabetologia was subject to the UK Code.

The Panel noted that Takeda Europe had placed the advertisement and was taking responsibility under the Code.

The Panel noted that the claim 'There are no longterm cardiovascular concerns regarding the use of Actos' appeared as a prominent diagonal highlight band across the top right-hand corner of the advertisement. The Panel considered that this claim was the main message of the advertisement and was put forward as a feature of the product which set it apart from rosiglitazone. The Panel noted however that Section 5.1, Pharmacodynamic properties, of the SPC stated 'Although the study [PROactive, a cardiovascular outcome study] failed to reach its primary endpoint, which was a composite of all-cause mortality, non-fatal myocardial infarction, stroke, acute coronary syndrome, major leg amputation, coronary revascularisation and leg revascularisation, the results suggest that there are no long-term cardiovascular concerns regarding the use of pioglitazone. However, the incidences of oedema, weight gain and heart failure were increased. No increase in mortality from heart failure was observed.'

Section 4.3, of the SPC stated that pioglitazone was contraindicated in patients with cardiac failure or history of cardiac failure (NYHA stages I to IV). Section 4.4, Special warnings and precautions for use, gave detailed information on fluid retention and cardiac failure stating that pioglitazone could cause fluid retention which might exacerbate or precipitate heart failure.

The Panel noted that the advertisement also included the claims that 'Actos… reduces cardiovascular (CV) risk markers', 'Actos is the only thiazolidinedione (TZD) with clinical and safety evidence from a large cardiovascular outcome study in its prescribing information' and 'Results from the CV outcome study, PROactive, confirmthere are no long-term CV concerns, such as increased risk of MI, regarding use of Actos…'.

The Panel considered that the advertisement sought to minimize prescribers' concerns regarding the CV safety profile of Actos. The claim at issue ('There are no long-term cardiovascular concerns regarding the use of Actos') was not consistent with the SPC which was more qualified regarding the outcome of the study by the use of the phrase 'the results suggest [emphasis added] there are no long-term cardiovascular concerns…'. In any event the information in Section 5.1, Pharmacodynamic properties, did not take priority over Sections 4.3, Contraindications, and 4.4, Special warnings and precautions for use. In the Panel's view it was not sufficient to rely on the prescribing information in the advertisement to provide the cautionary note about heart failure. A breach of the Code was ruled.

The Panel considered that the advertisement gave the impression there was no need to worry about long-term cardiovascular concerns and this was not necessarily so given that fluid retention caused by pioglitazone might exacerbate or precipitate heart failure and that pioglitazone should be discontinued if any deterioration in cardiac status occurred. The product was contraindicated in patients with, or with a history of, heart failure. The claim at issue was misleading, did not reflect the entire situation and did not encourage the rational use of Actos. Thus the Panel ruled breaches of the Code.

With regard to the use of the advertisement after the MHRA had ruled that another advertisement, placed by Takeda UK, was in breach of the advertising regulations, the Panel noted that the final date for copy for the May 2008 edition of Diabetologia was 31 March. The agreed action date between the MHRA and Takeda UK was 5 March. Takeda Europe therefore had time to change the advertisement in Diabetologia. The published report on the MHRA website stated that action had been agreed on 19 March.

The Panel noted the MHRA published report that claims relating to pioglitazone did not reflect the balance of risks and benefits as stated in the SPC. The Panel considered that the same point applied to the advertisement in Diabetologia. Given all the circumstances the material should have been amended. In addition the Panel was concerned about the implications for patient safety given its rulings above. Thus the Panel ruled a breach of Clause 2 of the Code.
