    Report summary

    Sasha Drysdale died on 28 March 2023 in hospital as a consequence of acute myeloid leukaemia transformed from myelodysplastic syndrome. She had previously been prescribed clozapine for treatment-resistant schizoaffective disorder and was detained under section 3 of the Mental Health Act 1983 at the time of her death. The concern raised was that further research is needed to establish whether clozapine materially increases the risk of certain blood cancers.

    PFD Monitor interpretation

    Potential increased risk of certain blood cancers among patients taking Clozapine

    Wider context from the report

    “The court heard evidence as to a small number of studies conducted internationally which, whilst having small sample sizes, could be read as suggesting an increased incidence of certain forms of blood cancer amongst those taking Clozapine. I am concerned that further research is needed to either refute or confirm whether or not taking Clozapine materially increases the risk of a patient developing certain blood cancers. ”

    A causal relationship between clozapine and blood cancer has not been established or confirmed by current evidence.

    Verbatim wording from the response

    “A causal relationship between Clozapine therapy and blood cancer (leukaemia) is at the current state of scientific knowledge not established and therefore not referenced in the SmPC.”
