Case Summary

Shire complained about two leavepieces and a journal advertisement promoting Asacol (modified release mesalazine) issued by Procter & Gamble. Asacol was indicated for the treatment of mild to moderate acute exacerbation of ulcerative colitis and for the maintenance of remission thereof. Asacol was also indicated for the maintenance of remission in Crohn's ileocolitis. Mesalazine was a 5- aminosalicylate (5-ASA).

The detailed response from Procter & Gamble is given below.

Shire alleged that the strapline 'confidence in colitis' beneath the product logo without an equally prominent reference to Asacol's indication promoted Asacol beyond its indication and also overstated the clinical benefits.

Shire noted that there were a number of different types of colitis ie: amoebic, collagenous, common variable immunodeficiency, drug induced, haemorrhagic, infective, ischemic, lymphocytic, post-radiation, pseudomembranous and ulcerative.

During inter-company dialogue, Procter & Gamble relied on the prominence of the correct indication, ulcerative colitis, on the one-page leavepiece, experience of health professionals with the product and the incidence of ulcerative colitis in the UK compared to other forms of colitis. Shire disagreed with Procter & Gamble's assertion that the leavepiece referred to 'ulcerative colitis' anywhere on its face. The references to ulcerative colitis were in any event too far removed from the strapline and logo cluster as well as insufficiently large to qualify it due to the close proximity of this strapline with the Asacol product logo.

Shire also alleged that the word confidence in 'confidence in colitis' encouraged use outside the terms of the summary of product characteristics (SPC) and licensed indications (as explained above) and implied superlative, special performance of the product which Procter & Gamble had failed to substantiate.

The Panel noted that Asacol was indicated for the treatment of mild to moderate acute exacerbations of ulcerative colitis and for the maintenance of remission thereof. It could also be used for the maintenance of remission in Crohn's ileo-colitis. The Panel noted that the front page of the leavepiece was headed 'Examples of how to write a script for Asacol 800mg MR tablets' beneath which was a table of possible dosing regimens and examples of how the prescription would be written. Three regimens were given 'Maintenance of remission (1.6g/day)', 'Mildacute UC (2.4g/day)' and 'Moderate acute UC (4.8g/day)'. The only time the term 'ulcerative colitis' was used in full was in the indications section of the prescribing information on the reverse.

The Panel considered that promotional material must be clear about the relevant indication for the medicine. The reader's attention would be drawn to the strapline 'confidence in colitis' in the bottom right-hand corner of the page. It appeared that Asacol could be used in all types of colitis which was not so. The Panel considered that the strapline 'confidence in colitis' was inconsistent with the Asacol SPC as alleged. A breach of the Code was ruled.

The Panel did not consider that 'confidence' per se implied a special merit that had not been substantiated nor did it imply a superlative. Prescribers should expect to be able to prescribe any licensed medicine with confidence. No breach of the Code was ruled.

A journal advertisement featured the photograph of a commuter reading a broad sheet newspaper. The headline running across the front and back pages was 'Back to normal everyday life …' '… Sooner − Asacol 4.8g/day vs. mesalazine 2.4g/day'. A claim beneath the photograph read 'For moderately active UC Higher dosing 4.8g/day Asacol 800mg MR tablets for fast, effective relief from a flare-up. Great news'.

Shire alleged that the claims that Asacol's performance was 'Great news' and that it could return a patient's life 'back to normal' – ie the preulcerative colitis state – were unsubstantiable.

Shire was concerned about the heading 'Back to normal everyday life … Sooner – Asacol 4.8g/day vs. mesalazine 2.4g/day'. Ulcerative colitis was a chronic condition; patients had cycles of remission and relapse. Many patients in remission still had some symptoms. Procter & Gamble had not quantified what was meant by 'normal'. Shire alleged that 'normal', particularly in the phrase 'back to normal' (emphasis added), implied the patient's life was returned to the pre-ulcerative colitis state which was clearly not so as maintenance medicine was still needed. Shire alleged that the claim 'Back to normal everyday life …' was not balanced or fair, was ambiguous, could not be substantiated and was exaggerated.

Shire was also concerned that given the cyclical nature of remission and relapse occurring with ulcerative colitis, the claim that patients could be 'normal' again after taking Asacol was of poor taste, and did not maintain high standards.

Shire alleged that the superlative 'Great' in relation to Asacol was inappropriate. The reference to 'Great news' clearly referred to the claim 'Back to normal everyday life…' '…Sooner – Asacol 4.8/day …'. Procter & Gamble had not qualified 'Great' nor had it provided evidence to substantiate it.

The Panel noted that the headline read 'Back to normal everyday life…' '… Sooner …'. The advertisement showed a commuter reading his newspaper on a busy train. The Panel did not consider that the advertisement implied that Asacol would return patients to the pre-ulcerative colitis state. 'Normal' was used to describe 'life' and implied that, despite still having ulcerative colitis, a patient could resume everyday activities. The Panel did not consider that 'normal' would be read as describing the patient's disease state. In the Panel's view the claim was not unbalanced or unfair and it could be substantiated. The claim did not exaggerate the clinical efficacy of Asacol. The Panel did not consider that the claim was in poor taste or failed to maintain high standards. No breach was ruled.

With regard to the claim 'Great news' the Panel noted that it was not a superlative. Fast, effective relief from an ulcerative colitis flare up would be 'Great news'. Beneath this claim was the further claim that Asacol 4.8g/day provided relief from rectal bleeding and increased stool frequency 10 days faster (median time to symptom relief 19 days vs 29 days) than mesalazine 2.4g/day (Marion et al 2006). The Panel did not consider that the claim was exaggerated as alleged. No breach was ruled.

The Panel noted that the product logo incorporated the strapline 'confidence in colitis'. The product logo appeared in the bottom right-hand corner of the advertisement where it was most likely to attract the reader's attention. The Panel noted its ruling above. The claim 'confidence in colitis' would become associated with Asacol. 'Colitis', however, was a general term and required qualification for the precise disease state to be described. The Panel noted that the advertisement referred to 'moderately active UC' although again the only reference to 'ulcerative colitis' was in the prescribing information. However, the strapline, which was in larger font than the reference to UC, implied that Asacol could be used in all types of colitis and this was not so. The Panel considered that the strapline 'confidence in colitis' was inconsistent with the Asacol SPC as alleged. A breach of the Code was ruled.

 The prescribing leavepiece highlighted the fact that oral mesalazine products were not interchangeable and thus should not be prescribed generically. Shire noted that the leavepiece incorporated the views of a named doctor only and Procter & Gamble had failed to substantiate all the claims made in such opinion by reference to either the opinion of the majority of health professionals or other prescribing guidance.

The doctor's opinion as stated in the leavepiece, read: 'Similar to certain other drugs, for example anti-convulsives, mesalazine should be prescribed by brand name. Until we get hard evidence that two different mesalazine formulations are therapeutically equivalent and have the same benefits and sites of action, I consider that patients should not be switched and are kept on their existing brand name mesalazine preparation'.

Shire alleged that the above was misleading in a promotional context as it was one health professional's opinion and Procter & Gamble had not substantiated all the claims within this quotation, in particular the statement that 'patients should not be switched and are kept on their existing brand name mesalazine preparation'. Procter & Gamble had not quoted a source that showed that this statement either represented all if not the majority of health professionals or provided prescribing guidance to justify the same. Shire noted that the MIMS February 2009 guidelines stated 'Different aminosalicylates and their various forms are not interchangeable and are designed to release active drug at different sites along the colon. They should be prescribed according to their mode and site of action and the brand name should always be specified'. The MIMS guidance did not, however, go on to state that switching from an existing prescription should be avoided. As the named doctor expressly acknowledged in his quotation, there was no data to substantiate this claim (that patients on Asacol should not be switched to other 5-ASAs).

The Panel noted that the quotation from the named doctor 'I consider that patients should not be switched and are kept on their existing brand name mesalazine preparation' was unqualified. It might well be the view of the doctor quoted but promotional material had to reflect the balance of the evidence. The other supporting documentation referred to the differences between the various preparations and the need to avoid unplanned substitution. However it might be necessary to change patients' therapy for clinical reasons. In this regard the Panel noted Procter & Gamble's submission that patients should not be switched between different oral mesalazine products unless there were specific clinical reasons to do so. This advice was not given. Thus the Panel considered that the quotation at issue was misleading as alleged. A breach of the Code was ruled.
