Case Summary

A complainant, who described him/herself as a concerned UK health professional, complained about Prostap (leuprorelin acetate) material produced by Takeda UK hosted on the website of the journal ‘Guidelines in Practice’. Prostap was available in two formulations, Prostap SR DCS (dual chamber syringe) and Prostap 3 DCS; both were indicated for use in certain patients with breast cancer. Additionally, Prostap SR DCS was indicated for the preservation of ovarian function in pre-menopausal women with neoplastic disease undergoing chemotherapy treatment that could cause premature ovarian insufficiency.

The complainant drew attention to a webpage on the Guidelines in Practice website which presented a Formulary Decision Guide on Prostap DCS and provided details of the link to the prescribing information. The complainant stated that neither the Formulary Decision Guide nor the prescribing information included the statement that was added to Section 5.1 of the summary of product characteristics (SPC) in August 2019 that Prostap 3 DCS should not be used for preservation of ovarian function. The complainant stated that, in that regard, the Formulary Decision Guide promoted an off-licence indication as it listed ovarian preservation as an indication for use. The complainant considered that patient safety was at issue.

The detailed response from Takeda is given below.

The Panel noted that the material at issue was primarily about the use of Prostap DCS (either formulation) in patients with breast cancer. Information on the use of the two formulations had been included in the indication section within the Formulary Decision Guide. The first bullet point in that section stated ‘Prostap SR DCS and Prostap 3 DCS are licensed for breast cancer as follows:’ and so it was immediately clear to the reader that the information which followed would relate to both formulations. The second bullet point, however, was presented in a different style and stated ‘Preservation of ovarian function:’ without making it clear at the outset as to which formulation the information which followed referred. That it only referred to Prostap SR DCS was in the sentence which followed. The Panel considered that some readers might read the preservation of ovarian function indication and assume that it applied to both formulations particularly if they did not go on to read the text below.

The Panel considered that when two formulations of one product had differing indications such that one formulation was licensed for use where the other one was not, particular care needed to be taken to avoid any confusion. In the Panel’s view, such differences should be made abundantly clear to ensure the rational use of each formulation. The Panel noted that Prostap 3 DCS had not been granted a licence for use in the preservation of ovarian function due to lack of efficacy data and so in that regard it was extremely important that clinicians did not use it for such. The Panel noted that the MHRA had required additional text to be added to the Prostap 3 DCS SPC stating that ‘Prostap 3 should not be used for preservation of ovarian function’. Although there was no statement in the Formulary Decision Guide that Prostap 3 DCS could be used for the preservation of ovarian function there was also no statement that it should not be so used, thus drawing readers’ attention to the very clear distinction between the two Prostap formulations in that regard. The Panel accepted that it was unusual for material to state what a product was not licensed for but, given the reference in the Formulary Decision Guide to the use of Prostap SR DCS for the preservation of ovarian function and the MHRA’s requirement that the Prostap 3 DCS SPC include a statement that it should not be used for such, the Panel considered that by not clearly and unambiguously stating that Prostap 3 DCS should not be used for the preservation of ovarian function, Takeda had failed to maintain high standards and a breach of the Code was ruledthat was upheld on appeal.

The Panel noted that the layout of the combined Prostap SR DCS and Prostap 3 DCS prescribing information dated May 2019 was such that emboldened sub-headings distinguished between the breast cancer indications for Prostap SR DCS and Prostap 3 DCS and the indication of preservation of ovarian function for just Prostap SR DCS. Although it noted Takeda’s submission that there was no requirement in the Codeto refer to any therapeutic indications for which a product was not licensed, the Panel considered that patient safety and the rational use of medicine was paramount and in that regard any possibility of confusion must be avoided. The Panel noted that the Code required prescribing information to include, among other things, ‘serious adverse reactions and precautions and contra-indications relevant to the indications in the advertisement’. In the Panel’s view, the statement required by the MHRA that Prostap 3 DCS should not be used to preserve ovarian function, although not within Section 4.3 of the Prostap 3 DCS SPC (Contra-indications), was an important precaution relevant to the indications referred to in the Formulary Decision Guide and in that regard should have been included in the prescribing information to reinforce to readers that Prostap 3 DCS should not be used to preserve ovarian function. The prescribing information thus did not include the required information and so a breach of the Code was ruled that was upheld following an appeal from Takeda. The Panel ruled a further breach as high standards had not been maintained. Upon appeal from Takeda the Appeal Board considered that its concerns were adequately covered by the prior ruling of a breach of the Code and therefore it ruled no breach the Code in relation to high standards.

Although the Panel considered that more should have been done to ensure that prescribers were clear that Prostap 3 DCS should not be used to preserve ovarian function, it nonetheless did not consider that, on the evidence before it, the product had been promoted for that use as alleged. No breach of the Code was ruled.

The Panel noted that a ruling of a breach of Clause 2 was a sign of particular censure and reserved for such. The Panel noted its concerns above but considered that, on balance, a ruling of a breach of Clause 2 was not warranted. No breach of the Code was ruled.
