Background and Research focus

Professor Sylvie Freeman is co-director of the Clinical Immunology Service, leading Immunophenotyping for the diagnosis and monitoring of haematological malignancies. The service provides a distinct interface between the University’s substantial scientific expertise in immunohaematology and the clinical investigation and management of blood cancers and immunodeficiency in the NHS and for clinical trials. Under her direction the University of Birmingham Clinical Immunology Service has established an international reputation for flow cytometric AML monitoring, serving as the hub reference laboratory in the UK.

Sylvie’s long standing research is focussed on predicting treatment resistance in acute myeloid leukemia (AML) and myelodysplasia principally by monitoring residual disease (MRD). The heterogeneity of AML with respect to both disease biology and patient-specific clinical factors requires advances in personalised risk stratification to improve therapeutic outcomes.   Although not a common malignancy, treatment of patients with AML is disproportionately expensive particularly if patients have treatment intensified by stem cell transplantation. Hence, there are major economic as well clinical benefits to be gained by better selection of patient-appropriate targeted therapies. With this in mind her group have developed and implemented immunophenotypic assays to evaluate and monitor AML during chemotherapy and allogeneic stem cell transplantation, recently extending this to novel assays tracking leukemic stem cell enriched populations with national /international collaborators.

Over the course of the last few years her laboratory have undertaken numerous studies supported by CRUK /NIHR /LLR evaluating AML residual disease monitoring by flow cytometry (MFC-MRD) within the UK MRC / NCRI acute myeloid leukaemia (AML) trials. The first study of MRD in older AML patients (NCRI AML16, CRUK funded) generated data (Freeman et al JCO 2013) that underpins MRD-directed therapy in older patients (NCRI AML18 trial). The collaborative analysis of younger patients in AML17 (NIHR funded, Prof Grimwade King’s College, London)) has generated key data on the prognostic relevance of molecular MRD (Ivey et al NEJM 2016) along with flow cytometric MRD (Freeman et al JCO in press) that are currently being implemented for MRD directed therapy in the younger AML patients (NCRI AML19). Additionally, there is a collaborative focus on developing novel assays tracking leukemic-stem-cell-enriched populations, mass cytometry deep phenotyping and combining genetic profiling with flow cytometric data. In collaboration with Prof Craddock / Prof Vyas (Oxford), the potential of LSC tracking in parallel with conventional MFC MRD pre and post allogeneic transplantation was established (Bradbury et al, Leukemia 2015) and is part of a prospective randomised RIC-transplantation programme (FIGARO trial, BloodWise funded). Her group are also testing a simple assay that could potentially identify prior to treatment AML patients unlikely to respond to standard intensive chemotherapy by blood frequency of stem-cell-like blasts (BloodWise funded, collaboration with Prof Russell/Prof Hills for NCRI AML18) and evaluate expression of cell surface molecules that are targets for established and novel antibody directed AML therapy (Khan et al Leukemia 2017). Collectively, these studies will provide independent prognostic information and develop more personalised treatment approaches in AML and high risk myelodysplasia.

Other activities

Professor Freeman is a Honorary Consultant Haematologist at the University of Birmingham who has an established track record for characterisation of surface markers in myeloid malignancies. She is a longstanding member of the UK National Cancer Research Institute Acute Myeloid Leukaemia Working Party and more recently the European LeukemiaNet AML MRD Working Group. Professor Freeman also serves as a Co–Investigator in several UK NCRI AML trials including AML16, AML19 and FIGARO. She also has a part time role at the WHIMM in Oxford for developing AML monitoring assays. Additionally, Professor Freeman has developed collaborations with the molecular expertise at KCL, Cambridge and international colleagues with the critical aim of optimising ‘fit for purpose’ precision assays that will best inform treatment of AML including for novel therapies.  Alongside her research commitments, Professor Freeman contributes to teaching on the MBChB, BMedSci and MPharm programmes.
