On 18 September 2017, a marketing authorisation valid through the European Union (EU) was issued for midostaurin in combination with standard daunorubicin and cytarabine induction and high-dose cytarabine consolidation chemotherapy and for patients in complete response followed by midostaurin single agent maintenance therapy, for adult patients with newly diagnosed acute myeloid leukaemia (AML) who are Fms-like tyrosine kinase 3 mutation positive and as monotherapy for the treatment of adult patients with aggressive systemic mastocytosis (ASM), systemic mastocytosis with associated haematological neoplasm (SM-AHN) or mast cell leukaemia (MCL). The recommended dose of midostaurin is 50 mg orally twice daily for AML and 100 mg orally twice daily for ASM, SM-AHN and MCL. Midostaurin was evaluated in two pivotal studies. Study A2301 (RATIFY) included 717 patients with AML. Overall survival (OS) was statistically significantly different between the two groups, and the median OS was 74.7 months in the midostaurin+daunorubicin+cytarabine group and 25.6 months in the placebo+daunorubicin+cytarabine group (HR 0.774; 95% CI 0.629 to 0.953; p=0.0078). Study D2201 included 116 patients with ASM, SM-AHN or MCL. An overall response rate, by IWG-MRT/ECNM (international working group – myelofibrosis research and treatment/European competence network on mastocytosis) criteria of 28.3% was observed in all patients and 60.0%, 20.8% and 33.3% in patients with ASM, SM-AHN and MCL respectively. The most common adverse drug reactions (ADRs) with midostaurin treatment in AML were febrile neutropenia, nausea, exfoliative dermatitis, vomiting, headache, petechiae and fever. In ASM, SM-AHN, MCL the most common ADRs were nausea, vomiting, diarrhoea, peripheral oedema and fatigue. The objective of this paper is to summarise the scientific review of the application leading to regulatory approval in the EU.
