Case Summary

​​Janssen-Cilag voluntarily admitted a breach of the Code in that a promotional email for Invokana (canagliflozin), with outdated prescribing information, was inadvertently sent to general practitioners by its mailing agency.

Invokana was indicated in adult patients with type 2 diabetes mellitus to improve glycaemic control in certain patients as monotherapy or as added-on therapy. 

As Paragraph 5.6 of the Constitution and Procedure required the Director to treat a voluntary admission as a complaint, the matter was taken up with Janssen. 

​Janssen explained that the Invokana prescribing information was updated in December 2015 to reflect the addition of the uncommon side effect of 'renal failure (mainly in the context of volume depletion)' and consolidation of non-serious, uncommon side effects associated with renal failure previously listed in prescribing information (blood creatinine increased, blood urea increased, blood potassium increased, blood phosphate increased). Therefore Janssen did not believe that the outdated prescribing information had risked patient safety. A copy of the Invokana prescribing information from August 2015 and an annotated copy from December 2015, indicating the changes, were provided. 

Janssen acknowledged a breach of the Code since the expired prescribing information included on the mailer was not consistent with the summary of product characteristics (SPC) at the time of publication. 

The detailed response from Janssen is given below. 

The Panel noted that on 7 January 2015, the agency emailed Janssen to confirm that all old versions of the Invokana prescribing information had been deleted from its system. As prescribing information was an integral part of the promotional material provided by the agency, it was assumed that deletion of old prescribing information would, at the same time, delete the materials at issue. 

On 16 March there was an email exchange between the agency and Janssen regarding the 'Invokana Cost Change email'. Neither party referred to 'updated' material or cited the reference number so that the item at issue could be correctly identified. Having received confirmation that the email was approved for use it appeared that there was a verbal instruction from the agency's account team to its IT team to 'resend' the mailer. The Panel assumed that the little information given was sufficient to allow the correct item to be identified. The IT team retrieved the old mailer from the sent items on its mail server and resent it. The Panel considered that although the agency had not previously realised that material was effectively archived on its mail server, both parties should have been clearer about the item at issue particularly given the importance of not sending outdated material. 

The Panel noted that, Janssen's agency had resent a previous document which included prescribing information which Janssen submitted did not reflect the most recent SPC. The company had updated its prescribing information by consolidating a previous list of what it described as non-serious, uncommon side effects associated with renal failure into the statement 'renal failure (mainly in the context of volume deletion)'. 

The Code required the prescribing information to be included in promotional material and the supplementary information stated that the prescribing information must be consistent with the SPC. Clause 4.2 listed the elements of the prescribing information and in relation to adverse reactions the requirement was for a succinct statement of common adverse reactions likely to be encountered in clinical practice, serious adverse reactions and precautions and contra-indications relevant to the indications in the advertisement, giving in abbreviated form, the substance of the relevant information in the SPC, together with a statement that prescribers should consult the SPC in relation to other adverse reactions.

The Panel noted that the adverse reaction at issue was neither common nor, according to Janssen, serious. In that regard it was not one of the required elements of prescribing information listed in Clause 4.2. Nonetheless, information even about uncommon side effects still had to be accurate. The Panel noted that the change made to the Invokana prescribing information in December 2015 was to consolidate a list of conditions symptomatic of renal failure. The email sent in error included that list instead of the consolidated statement 'renal failure (mainly in the context of volume depletion)'. The Panel considered that although the prescribing information on the email sent in March 2015 was not the most up-to-date version, prescribers had nonetheless been given the substance of the relevant information in the SPC as required. No breach was ruled​
