Background and Research focus

Dr Guy Pratt is an Honorary Consultant Haematologist at the Heart of England NHS Foundation Trust and in the School of Cancer Sciences, University of Birmingham. His main research interests are multiple myeloma and chronic lymphocytic leukaemia (CLL) and he is actively involved in supporting basic research, in developing guidelines, in clinical trials in these diseases and sits on the executive board of the UK Myeloma Forum. Multiple myeloma is the second most common haematological cancer characterized by neoplastic plasma cells accumulating in the bone marrow. Dr Pratt has a long-standing research interest in characterizing tumour specific CD8+ and CD4+ T cells responses and the T cell disturbance in blood and bone marrow in patients afflicted with plasma cell disorders. He is also interested in examining differences in the tumour cell microenvironment in multiple myeloma and the premalignant mono gammopathy of unknown significance (MGUS) state. Collectively, these studies will provide a more in-depth understanding of the pathogenesis of myeloma leading to the development of new and improved treatments. Dr Pratt has also fostered numerous collaborations with national and industry based groups focused on research and developing clinical drugs to treat CLL. In particular, he is currently chief investigator for a national phase I/II clinical trial assessing the efficacy and safety of the drug olaparib, a poly ADP ribose polymerase(parp) inhibitor in CLL.

Other activities

Guy is an Honorary Consultant Haematologist at the Heart of England NHS Foundation Trust. As a Consultant Haematologist, he is involved in all aspects of general Haematology but has a particular interest in Haemato-Oncology. Guy also makes substantial contributions in mentoring and teaching medical students and is on the Graduate Studies Committee for the School of Cancer Sciences. Guy has developed a considerable number of national and industry based collaborations with a mounting publication output (80+ peer reviewed publications) and is involved in the publication of national myeloma guidelines including being clinical lead for the ongoing NICE myeloma guideline. Moreover, he regularly peer reviews for a number of journals, grant holders and frequently serves as an external examiner. Finally, Guy regularly lectures to patients and relatives on Myeloma Info days organised by the patient support group Myeloma UK and is a Trustee for the Waldenstroms Macroglobulinaemia UK patient support group.
