Case Summary

​​Takeda UK complained about a Lutrate (leuprorelin acetate depot injection) promotional email (ref AMCo/LUT/1115/0027) sent by Amdipharm Mercury Company (AMCo) to health professionals and budget holders in the NHS about the availability of a new formulation of leuprorelin with the potential for cost savings to the NHS. 

The detailed response from AMCo is given below. 

Takeda alleged that AMCo had falsely implied that Lutrate and Prostap DCS were interchangeable and could be used for the same indications in prostate cancer. Lutrate had a much narrower licensed indication which Takeda alleged could lead to patients being prescribed Lutrate inappropriately. This was promotion outside the marketing authorization and only a limited number of Prostap DCS patients would be eligible for Lutrate. The email was likely to lead GP practices to overestimate the cost savings they could achieve by using Lutrate in place of Prostap DCS which was alleged to be misleading and did not encourage rational use. 

The Panel noted that Prostap and Lutrate were both leuprorelin depot injections and in the Panel's view, the email implied that the two medicines were interchangeable. The Panel noted however that the indications for Prostap were broader than those for Lutrate. The Panel did not accept that the differences in indication were made clear. The impression was that the only difference between the medicines was the cost. No detail had been provided regarding the cost comparison but it again implied the products were interchangeable, ie Lutrate could be used whenever Prostap was used. This was not so. The Panel considered that the impression from the cost comparison and a poll was that Lutrate and Prostap were interchangeable. This was inconsistent with the Lutrate SPC and the Panel ruled a breach of the Code. This impression was not negated by the use of the term 'for eligible patients'.

 Neither Takeda nor AMCo provided details about the basis of the cost comparison, the number of patients and what proportion of patients could be changed from Prostap to Lutrate. The impression was that all Prostap patients could be changed to Lutrate which was not so. The Panel considered that the claims for cost savings were misleading and did not promote the rational use of Lutrate as alleged and breaches of the Code were ruled. 

Further only efficacy data regarding Lutrate's testosterone suppression was included with no balance of safety information regarding common adverse events or withdrawals due to adverse events which was alleged to be an unbalanced view of the evidence. 

The Panel noted that there was no mention of adverse events in the body of the email. The only information about common adverse events or withdrawals due to adverse events was in the prescribing information. The Panel did not consider that this necessarily meant that the email was an unbalanced view of the evidence as alleged. It noted that the material at issue was not lengthy and that leuprorelin was not a new medicine, the formulation was new. The SPC stated that most of the treatment related adverse events reported were mainly subject to the specific pharmacological action of leuprorelin and associated with testosterone suppressing therapy. Local adverse reactions reported after injection were similar to those with similar products administered via intra-muscular [injection]. The email did not state nor imply that there were no adverse events etc. The Panel did not consider that the email was unbalanced as alleged and ruled no breach of the Code. 

Takeda further alleged that the claim 'A novel leuprorelin formulation to maintain effective testosterone suppression' was misleading and disparaging since it implied that Lutrate offered some advantage over other leuprorelin formulations in terms of testosterone suppression. This had never been established. 

The Panel considered that the claim 'Novel formulation to maintain effective testosterone suppression' implied that the novel formulation maintained testosterone suppression rather than the leuprorelin. Although there was no mention of Prostap in this section as the active ingredients of both medicines was leuprorelin, there was an implication that Lutrate was an improvement over Prostap in relation to maintenance of effective testosterone suppression. The Panel considered that the claim implied a special merit which had not been established and that the claim disparaged other formulations of leuprorelin. Breaches of the Code were ruled.

Takeda alleged that the claim 'Lutrate is simple and easy to administer' had not been substantiated and was a hanging comparison. Takeda stated that since Prostap DCS was the obvious alternative treatment for patients eligible for Lutrate, the claim would likely be interpreted by prescribers as indicating that Lutrate was at least as simple and easy to administer as Prostap DCS. 

No evidence to support this assertion was referenced in the email, or by AMCo during inter-company dialogue. Takeda alleged that administration of Lutrate was, in fact, a more complex process than administration of Prostap DCS. The Panel noted that the claim 'Lutrate: simple and easy to administer' was followed by 8 illustrations of the steps needed to prepare the medicine and the injection area for administration. There was no mention of Prostap in this section. The first mention of Prostap in the email was in the following section. The Panel noted that the complainant had the burden of proving their complaint on the balance of probabilities. The Panel did not accept that the claim was a comparison; it was therefore not a hanging comparison as alleged. Readers would not necessarily interpret the claim as being that Lutrate was at least as simple and easy to administer as Prostap. The Panel ruled no breaches of the Code. 

Takeda alleged that given its continued concerns and the range of clauses alleged to have been breached, AMCo's conduct in relation to this material suggested a failure to maintain high standards and brought discredit to and reduced confidence in the industry. 

The Panel noted its rulings above. It considered that the lack of clarity regarding the comparison of Lutrate's indications and how these compared to Prostap and the general claim for cost savings ruled in breach meant that high standards had not been maintained and a breach of the Code was ruled. 

The Panel noted that Clause 2 was a sign of particular censure. It did not consider that the material brought discredit upon or reduced confidence in the pharmaceutical industry. No breach of Clause 2 was ruled.​
