Case Summary

​Boehringer Ingelheim Limited and Eli Lilly and Company Limited (the Alliance) complained about the promotion of Victoza (liraglutide) by Novo Nordisk.  The material at issue was an exhibition panel (ref UK/VT/0318/0108) used by Novo Nordisk at the Diabetes UK Professional Congress, March 2018.  Victoza was a glucagon-like peptide-1 receptor agonist (GLP-1 RA) indicated for the treatment of adults with insufficiently controlled type 2 diabetes as an adjunct to diet and exercise.

The Victoza summary of product characteristics (SPC) stated it could be used as monotherapy when metformin was considered inappropriate due to intolerance or contraindications and could be used in addition to other medicinal products for the treatment of diabetes.  Section 4.1 of the SPC also stated that study results with respect to combinations, effects on glycaemic control and cardiovascular (CV) events and the populations studied could be found in Sections 4.4, 4.5 and 5.1 of the SPC.
Two thirds of the exhibition panel featured the photograph of a woman walking in the shade towards the viewer and about to turn left around the corner of a large building and into what appeared to be a sunnier aspect.  Wrapping around the corner of the building was the text 'In adults with insufficiently controlled type 2 diabetes change the course of treatment by reducing CV [cardiovascular] risk'.  This was followed by red text which was mostly about the same height as the woman and which read 'HbA1CV' such that 'CV' was in the foreground of the picture.  The headline across the top of the picture read 'Victoza: the only GLP-1 RA superior in preventing CV events vs placebo'.  To the right side of the picture, and in the remaining third of the panel were the following two paragraphs in bold font:
'Indication : Victoza is indicated for the treatment of adults with insufficiently controlled type 2 diabetes as an adjunct to diet and exercise.
Section 5.1: Both improvement of glycaemic control and reduction of CV morbidity and mortality are an integral part of the treatment of type 2 diabetes.'
The detailed response from Novo Nordisk is given below.
The Alliance alleged that the overall prominence of the two main claims on the stand 'Change the course of treatment by reducing CV risk' and 'Victoza: the only GLP-1 RA superior in preventing CV events vs placebo' combined with the imagery, would lead observers to conclude that the promotional message was weighted heavily towards the reduction of CV risk.  Victoza was not indicated for the reduction of CV risk but for the treatment of adults with insufficiently controlled type 2 diabetes as an adjunct to diet and exercise.  The CV benefits of Victoza were referred to only in Section 5 of the SPC and so should be promoted as added benefits of Victoza rather than as the main indication. The Alliance alleged that the overall balance of the stand promoted Victoza inconsistently with the SPC.
The Panel noted that Victoza had been available as a treatment for diabetes for a number of years.  According to Novo Nordisk the SPC had been updated in July 2017 following Marso et al, a cardiovascular outcomes trial for Victoza in type 2 diabetes patients with high CV risk (LEADER).  Section 5.1 of the SPC which included a section headed 'cardiovascular evaluation' with data from LEADER did not mention that the patients had high CV risk.  An earlier part of Section 5.1, headed clinical efficacy and safety, referred to LEADER as a large cardiovascular outcomes trial in 9340 type 2 diabetes patients at high cardiovascular risk.  The EMA assessment report referred to the need to include the patient population (Type 2 diabetes) in the indication.  The improvement of glycaemic control and the reduction of cardiovascular morbidity and mortality were an integral part of treatment of type 2 diabetes, best expressed in a single indication.  A separate cardiovascular prevention indication was not therefore appropriate.
It appeared to the Panel that the exhibition stand was a three dimensional advertisement with the woman and large building part being separated from the rest of the advertisement which framed the picture of the woman and the building.  The top of the frame and the right hand side promoted Victoza.  The Panel agreed that the message from the exhibition stand was in relation to CV risk.  This was set within the context of the treatment of type 2 diabetes.  Both parts of the exhibition stand referred to type 2 diabetes and the frame part of the exhibition stand included the indication and details from Section 5.1 of the SPC.  The Panel noted that visitors to the stand would be attending the Diabetes UK Professional Congress.
The Panel did not consider that the exhibition stand was unambiguously clear as submitted by Novo Nordisk.  However, the Panel considered that on balance, taken as a whole the exhibition stand was not inconsistent with the SPC as alleged and no breach was ruled.  The stand overall was not misleading as alleged thus the Panel ruled no breach of the Code.
The Alliance alleged that the claim 'Change the course of treatment by reducing CV risk' promoted Victoza's additional CV benefits as the primary reason to prescribe. This call to action was misleading and inconsistent with the SPC as it put undue emphasis on CV benefits observed in a clinical trial.
The Alliance noted that the main imagery of the exhibition panel depicted a pavement, adjacent to which was a wall with the word 'HbA1CV'.  A woman (presumably a type 2 diabetic) was walking down a shaded pavement, marked by HbA1c, about to turn a corner into the light part of the pavement marked CV.  This suggested that Victoza's added benefits with respect to CV risk were at least equally important as the licensed indication, which was glycaemic control of HbA1c.  Together with the above claim, the Alliance alleged that this was misleading and inconsistent with the SPC.
The Panel considered that the important factor was that the patient had type 2 diabetes.  The outcome of the CV study would be of interest to those that treated type 2 diabetes.  There was a change in the Victoza SPC and the company was fully entitled to draw attention to that change.  The benefits shown in the LEADER trial were in relation to high cardiovascular risk patients.  The Victoza SPC also referred to more general information which showed no increase in CV risk for liraglutide versus all comparators. 
The Panel considered that the claim 'Change the course of treatment by reducing CV risk' in conjunction with 'HbA1CV' emphasised the CV risk reduction with Victoza.  However the context and audience were important.  The frame part of the stand referred to a qualifcation, 'In adults with type 2 diabetes and high CV risk...'.  Given its ruling in point 1 above and taking all the circumstances into account the Panel did not consider that Novo Nordisk was promoting the additional CV benefits as the primary reason to prescribe Victoza as alleged.  In the Panel's view the mention of the CV benefits was not misleading or inconsistent with the SPC as alleged.  The Panel ruled no breach of the Code.  The stand was not misleading in this regard and no breach was ruled.
The Alliance alleged that given the position taken by Novo Nordisk during inter-company dialogue, Novo Nordisk had failed to maintain high standards and reduced confidence in the industry, in breach of the Code.  Novo Nordisk's promotional stand for Victoza at the Diabetes UK Professional Conference on 13 March 2018 demonstrated that it continued to promote Victoza in the manner complained about in inter-company dialogue.
The Panel noted the important role of inter-company dialogue.  Novo Nordisk had withdrawn a leavepiece without prejudice.  There were similarities between the leavepiece at issue in the inter-company dialogue and the exhibition stand, the subject of the complaint to the PMCPA.  However, Novo Nordisk had not agreed with The Alliance's view that the leavepiece was in breach of the Code.  It was disappointing that Novo Nordisk had not given The Alliance more details.  Novo Nordisk's letter of 4 January stated that the company now considered the inter-company matter resolved.  In the light of the content of the exhibition stand it appeared that The Alliance considered that the inter-company matter was not resolved.  The Panel appreciated the frustration for companies when issues raised and considered resolved at inter-company level appeared again in a different format.  The main difference with the photograph of the women turning the corner related to the claim 'In adults with type 2 diabetes' used in the leavepiece had been amended to 'In adults with insufficiently controlled type 2 diabetes; in the exhibition stand.  The Panel considered that there were differences between the leavepiece and the exhibition stand.  It did not accept that Novo Nordisk failed to maintain high standards as alleged and ruled no breach of the Code.
