Case Summary

A doctor complained about an advertisement for Acomplia (rimonabant) issued by Sanofi-Aventis and published in GP.

Acomplia was indicated as an adjunct to diet and exercise for the treatment of obese patients ([Body Mass Index] BMI ≥30kg/m2), or overweight patients (BMI >27kg/m2) with associated risk factor(s), such as type 2 diabetes or dyslipidaemia.

The complainant alleged that the advertisement was misleading and suggested that Acomplia could be used to treat all cardiometabolic risk factors associated with diseases such as diabetes mellitus and cardiovascular disease.

The suggestion that half of its effects on cardiometabolic risk factors were beyond those expected by weight alone was misleading and suggested that Acomplia had other as yet unproven effects on all cardiometabolic risk factors including those cited in its summary of product characteristics (SPC); this was not consistent with the licensed indication which was in essence to reduce weight in obese or overweight patients. If one of the consequences of this very specific use was an improvement in the overall cardiometabolic risk profile of patients then that was fine.

The advertisement implied that Acomplia had some, as yet unidentified, effect of reducing specific cardiometabolic risk factors and that it should therefore be used to treat overweight/obese patients with high-blood pressure, low HDL-c, high triglycerides, insulin resistance and abnormal inflammatory markers and HbA1c levels. What proof was there to suggest a direct and causal link between the effects of Acomplia on any of the latter parameters other than an indirect effect associated with weight reduction? If Acomplia was so effective in modulating dyslipidaemia it was Acomplia journal advertisement paradoxical that it had no significant effect on elevated LDL-c and total-c levels, both established cardiometabolic risk factors, a fact glaringly omitted from the advertisement?

Encouraging the unlicensed use of Acomplia was further evidenced by the nonsensical statement that cardiometabolic risk factors in overweight patients could be where you least expected them. The latter clearly suggested that obesity or being overweight should not be considered as a cardiometabolic risk in isolation but should consider the effect of Acomplia on other less obvious risk factors. Thus doctors were invited to pay scant regard to the specific indication in weight reduction with the promise that Acomplia additionally modulated other independent cardiometabolic risk factors independent of weight reduction.

The complainant alleged that the advertisement exaggerated the facts which were that being overweight was a recognized cardiometabolic risk factor in its own right and that Acomplia treated only this particular parameter; any suggestion that the effects of Acomplia in modulating cardiometabolic risk factors went beyond weight reduction was patently misleading.

The Panel noted that the left hand side of the advertisement featured an outline of an overweight patient with the statement ‘Cardiometabolic risk factors in overweight patients can be where you least expect them’. The right hand side was headed ‘Discover Acomplia’ followed by the licensed indication. This was followed by reference to cardiometabolic risk factors, listing established risk factors as elevated blood glucose, high LDL-c and high blood pressure and emerging risk factors as low HDL-c, abdominal obesity, high triglycerides, insulin resistance and inflammatory markers. These were followed by information about reductions in weight and waist circumference. The final part of this section stated that Acomplia compared to placebo demonstrated significantly greater improvements in glycaemic control, HbA1c, increases in HDL-c and reductions in triglycerides. This was followed by the claim ‘An estimated 50% of the effects of Acomplia on Cardiometabolic Risk Factors are beyond those expected from weight loss alone’.

The Panel considered that the overall impression of the advertisement was that Acomplia was to be prescribed in overweight patients because of its effects on all cardiometabolic risk factors, not that Acomplia was to be prescribed for weight management as an adjunct to diet and exercise for the treatment of obese patients and overweight patients with associated risk factors such as type 2 diabetes or dyslipidaemia. In that regard the Panel noted that the statement ‘Cardiometabolic risk factors in overweight patients can be where you least expect them’ appeared in very much larger type size than any of the information about weight loss. The emphasis of the advertisement was not on the licensed indication in the SPC but on the information on pharmacodynamic properties. This impression was reinforced by the strapline, ‘It’s not what you lose. It’s what you gain’. In that regard the Panel considered that the success or otherwise of Acomplia therapy should be measured by weight loss not by alterations in cardiometabolic risk factors.

The Panel considered that there was a difference between promoting a product for a licensed indication and promoting the benefits of using that product albeit that some of the benefits were specifically mentioned in the SPC.

The licensed indication was included in the advertisement but was not the most prominent message. The Panel did not accept Sanofi-Aventis’ view that the weight loss indication was clearly presented and given priority over the additional effects of Acomplia. It agreed with Sanofi-Aventis that weight loss was relatively more important in the SPC than the additional effects.

The Panel considered that the advertisement had not placed the cardiometabolic risk factors sufficiently within the context of the licensed indication. In the Panel’s view the most prominent message was that Acomplia was to be prescribed for its effects on cardiometabolic risk factors in overweight patients and this was inconsistent with the SPC. A breach of the Code was ruled. This ruling was upheld on appeal by Sanofi-Aventis.

The Panel accepted that approximately 50% of the mean improvements in glycaemic control (HbA1c), HDL-c and triglycerides in patients receiving Acomplia were beyond that expected from weight loss alone. This was clearly stated in the SPC. Thus effects on some cardiometabolic risk factors beyond those expected from weight loss alone had been established. The advertisement, however, stated that ‘Cardiometabolic Risk Factors include established and emerging factors…’. The Panel thus did not accept the submission that the claim ‘An established 50% of the effects of Acomplia on Cardiometabolic Risk Factors are beyond those expected from weight loss alone’ applied to three risk factors, HbA1c, HDL-c and triglycerides; it appeared to apply to them all. The claim was misleading in this regard and thus not capable of substantiation. Breaches of the Code were ruled. These rulings were upheld on appeal by Sanofi-Aventis.

The Panel did not consider that the circumstances justified a ruling that high standards had not been maintained. Nor did the Panel consider that the circumstances justified a ruling of a breach of Clause 2 of the Code which was reserved as a sign of particular censure. These rulings were upheld on appeal by the complainant.
