Case Summary

​A general practitioner complained about a Tresiba (insulin degludec) email sent by Novo Nordisk.

 The start of the email included the claims 'Get HbA1c DOWN with CONTROL' and 'NEW LOWER PRICE'. It gave details of a price reduction followed by 'You might be surprised by Tresiba treatment cost (Type 2 Basal only)'. The email then referred to a recent 35% price reduction and that studies in basal insulin had demonstrated that patients required a 10% lower insulin dose on Tresiba vs insulin glargine U100 (p= 0.0004) referenced to Vora et al 2015. This was followed by an asterisk which was explained beneath a comparison table as 'Type 2 Diabetes (basal oral): Tresiba = 0.39u/kg vs insulin glargine U100 = 0.43u/kg'.

The next claim was that patients required a 17% higher insulin dose on insulin glargine U300 vs insulin glargine U100 referenced to Bolli et al 2015. This was followed by another symbol which was also explained beneath the comparison table as 'Absolute daily basal dose at end of trial: insulin glargine U300 = 0.62u/kg vs insulin glargine U100 = 0.53u/kg'. A table then compared an illustrative dose (U), monthly cost and annual cost of Tresiba U100, Tresiba U200, Toujeo, (insulin glargine pre-flled pen; Sanof), Lantus (insulin glargine; Sanof) and Abasaglar (insulin glargine; Eli Lilly). At the doses chosen, Toujeo was the most expensive at £34.96 per month, then Tresiba (both U100 and U200 cost £34.04 per month), Lantus (£33.68) and Abasaglar (£28.64).

Tresiba was indicated for the treatment of diabetes mellitus. It was a basal insulin for once-daily administration.

The complainant took exception to the email as he had never given Novo Nordisk permission to send promotional material.

The complainant was concerned that the cost comparison chart which compared Tresiba with Lantus, Abasaglar and Toujeo was not evidenced based as there were no published clinical trials that directly compared Tresiba with the other insulins shown in the chart particularly given the lack of clinical evidence to demonstrate dose for dose equivalence on HbA1c effect.

Also the title, 'You might be surprised by Tresiba treatment cost (Type 2 Basal only)' seemed to relate only to type 2 basal diabetics. However, the studies used to make comparisons included type 1 diabetics. In addition it was not clear what was meant by the claim 'Successful reductions' and what comparison it was trying to make.

The detailed response from Novo Nordisk is given below.

The Panel considered that on the information provided by Novo Nordisk, in the absence of an agreement from the complainant to be identifed to Novo Nordisk, there was no evidence before the Panel to establish whether the complainant had given permission to receive promotional emails. The Panel thus ruled no breach of the Code.

The Panel noted that the cost comparison table in the email was followed by an explanation of the doses used. It appeared that the primary messages from the email, were that there was a 35% price reduction across all Tresiba presentations and that this reduced treatment cost compared favourably to other insulins in relation to treatment of type 2 diabetes. The prominent cost comparison table stated an illustrative dose and invited readers to directly compare the monthly and annual costs of Tresiba, Toujeo, Lantus and Abasaglar. In the Panel's view, the initial impression might be that there was direct comparative data, and that was not so. In the absence of such comparative data, the basis of the comparison should be made clear. In this regard, text three paragraphs beneath the table read 'Assumed illustrative dose for IGlar of 40U/ day. Comparable annual treatment costs calculated using dose ratios from the BEGIN meta-analysis, the EDITION 3 trial (for glargine U300), Toujeo SmPC and Abasaglar SmPC'. This was followed by further explanation of the costs etc and then the prominent claim 'Tresiba is now at a comparable treatment cost to glargine U100 (Lantus) and glargine U300 in type 2 diabetes patients treated with basal only therapy' referenced to Vora et al, Bolli et al and MIMS December 2016. Two highlighted boxes then followed, one referred to the 35% price reduction and the second to the Scottish Medicines Consortium (SMC) and the All Wales Medicines Strategy Group (AWMSG) approvals for use in type 1 and type 2 diabetics. Three bullet points concluded the email, the frst read 'Successful reductions in HbA1c', referenced to Rodbard et al 2013 and Bode et al 2013.

Vora et al was a meta-analysis of Tresiba and glargine in type 1 and type 2 diabetes mellitus (basal-bolus treated type 1, insulin naïve type 2 and basal-bolus treated type 2). The conclusions included that insulin naïve type 2 patients treated with Tresiba needed lower total doses of insulin than those treated with glargine. The results showed that the total daily dose at the end of trial was 10% lower (p=0.0004) with Tresiba in type 2 diabetic insulin naïve patients (end of trial dose Tresiba 0.39U/kg and glargine 0.43U/kg). In basal bolus type 2 diabetic patients the total daily insulin dose did not differ statistically between treatments (Tresiba 1.22U/kg and glargine 1.18U/kg).

Bolli et al compared the safety and effcacy of glargine 300U with glargine 100U in insulin naïve patients with type 2 diabetes.

The SPC for Toujeo stated that when switching from insulin glargine 100U to Toujeo this could be done on a unit-to-unit basis but a higher Toujeo dose (approximately 10-18%) might be needed to achieve target ranges for plasma glucose levels.

The Panel was concerned that the data in the cost comparison was from a number of trials. Tresiba was not compared with each medicine mentioned, for example the comparison with Toujeo was based on two comparisons between Toujeo and Lantus and the other between Tresiba and Lantus.

The Panel noted that the data used in the comparison table were from type 2 patients only on basal insulin and derived from two studies. In these circumstances, the Panel did not consider it was misleading to reference the comparisons in the table to Vora et al which also investigated type 1 patients. Thus the Panel ruled no breach of the Code on this narrow point.

The Panel noted its comments above about the comparison chart. The frst two paragraphs beneath the comparison table related to, and qualifed, the dose claims above the table rather than the data in the table. The third paragraph which was in less prominent font than the two paragraphs that immediately preceded it sought to explain the data in the comparison table. In the Panel's view, the assumptions used for the illustrative doses were not suffciently complete or prominent. The Panel considered that the comparison table was misleading and ruled breaches of the Code.

The claim 'Successful reductions in HbA1C' appeared beneath two highlighted boxes, one of which referred to type 1 and type 2 diabetes. Above the highlighted boxes was the prominent comparative claim about treatment costs for Tresiba in type 2 diabetes compared to glargine. It was not clear whether the following three bullet points including 'Successful reductions in HbA1c' related to type 1 and type 2 diabetes. However, Tresiba was indicated for use in both conditions and both conditions were referred to in the box immediately above. The referenced studies Rodbard et al was in type 2 diabetes patients and Bode et al 2013 was in type 1 diabetes patients. The Panel did not accept Novo Nordisk's submission that the prominent comparative claim vs Lantus and glargine U300 summarized the information presented in the first section. Visually it sat immediately above the highlighted boxes and, in the Panel's view, its prominence, position, green font and design gave the context for the claims beneath. The claim 'Successful reductions in HbA1c' might be read as applying to all three products, others might read it as a benefit for Tresiba compared to Lantus and glargine U300. There was some relevant data in Rodbard et al and Bode et al. Nonetheless, and on balance, it was not sufficiently clear. Breaches of the Code were ruled.

In relation to the allegation that it was not clear what was meant by 'Successful reductions in HbA1c', the Panel noted Novo Nordisk's submission about treat-to-target trials and their primary endpoints. The Panel did not consider the claim misleading on this point as alleged. The Panel did not consider that it was misleading to reference the claim to studies on both type 1 and type 2 patients given the reference to such patients in the box immediately above. The Panel ruled no breaches of the Code including that the company had not failed to maintain high standards.
