Case Summary

An anonymous, non-contactable complainant alleged that the prescribing information on a detail aid (ref UKIE-P-103-1115-117947(1)) for Blincyto (blinatumomab) produced by Amgen was incorrect and was not the most up to date version. Blincyto was indicated for certain patients with acute lymphoblastic leukaemia.

The detailed response from Amgen is given below.

The Panel noted that the complainant was anonymous and non-contactable. The Constitution and Procedure for the PMCPA stated that anonymous complaints would be accepted but that, like all other complaints, the complainant had the burden of proving his/her complaint on the balance of probabilities.

The Panel noted that the complainant alleged that the prescribing information on the detail aid in question was incorrect and not the most up to date but provided no details of why, in his/her view, this was so. It was not for the Panel to make out a complainant’s allegations and the complainant could not be contacted for more information.

The Panel noted Amgen’s submission that it assumed that the allegation related to the fact that Blincyto was licensed for a new indication (as monotherapy for the treatment of adults with Philadelphia chromosome negative CD19 positive B-precursor ALL in first or second complete remission with minimal residual disease (MRD) greater than or equal to 0.1%.) in January 2019. The Panel noted Amgen’s submission that there was no need to amend the prescribing information dated August 2018 on the detail aid at issue as a result of the new indication because the only changes to the prescribing information related to the new indication and the new dosing schedule for that indication and there were no new safety changes. The Panel further noted Amgen’s submission that the prescribing information for the indication stated in the detail aid in question was accurate and maintained updated at all times.

The Panel noted that the detail aid in question which was certified in November 2018 clearly related to Blincyto’s indication as monotherapy for the treatment of adults with Ph-CD19 positive relapsed or refractory B-precursor acute lymphoblastic leukaemia (ALL) which was stated on the cover. The Panel noted Amgen’s submission that this detail aid was withdrawn on 27 May 2020 and replaced with a new detail aid.

The Panel noted that some changes to an SPC might not necessarily have to be reflected in the prescribing information. For example, information relevant only to an indication not being promoted might not need to be included in the prescribing information.

The Panel was not an investigatory body and it judged complaints on the evidence provided by both parties. The Panel considered that the complainant had not discharged his/her burden of proof that the prescribing information on the piece of material at issue did not meet the requirements of Clauses 4.1 and 4.2 and in that regard the Panel ruled no breach of the Code.
