DIABETES and ENDOCRINOLOGY Name and Title of Academic Director Professor Solomon Tesfaye Overview of Experimental Medicine Research in Theme Main themes Diabetes a) b) c) d) Hypoglycaemia Studies in Type 1 diabetes CNS imaging and diabetes Biomarkers of diabetic autonomic neuropathy Endocrinology e) Endocrine hormone replacement. f) Treatment of hormone excess. Overview In hypoglycaemia we are planning to develop our work undertaking mechanistic studies which might explain mortality in both types of diabetes. We have entered into a collaborative research agreement with Eli Lilly, Indianapolis to develop this work in joint studies and are contributing to work with them and the FDA in clarifying the relevance of abnormal cardiac repolarisation in diabetes when developing new medications. We are planning collaborative studies exploring mechanisms of hypoglycaemia unawareness and closed loop treatment in Type 1 diabetes. In diabetic neuropathy we will be initiating novel studies that will identify objective, perfusion and fMRI correlates of pain in diabetes to develop of new and more effective analgesic compounds in painful diabetic neuropathy. In autonomic neuropathy we will explore the potential of heart rate variability as a predictor of autonomic neuropathy in prospective work and determine whether intensive intervention including new medication can prevent established neuropathy. In endocrinology our main goal is to translate new endocrine therapies into commercial products by 2017 including, Chronocort treatment of congenital adrenal hyperplasia and adrenal insufficiency, Infacort for the treatment of neonatal and infant congenital adrenal hyperplasia and adrenal insufficiency, High dose vitamin D for the replacement of vitamin D deficiency, glucocorticoid antagonists for the treatment of sub clinical Cushing’s disease and siRNA as therapy for Cushing’s disease. Achievements Hypoglycaemia and studies in Type 1 diabetes - We have published data from the ADVANCE database in a paper in the NEJM demonstrating an association between severe hypoglycaemia and subsequent mortality, which together with data from the ACCORD and VADT trials underpins our EM work exploring potential mechanisms in mortality. On the strength of this work and pilot data, our academic clinical fellow has been awarded a 3 year 1 PhD fellowship by the NIHR to complete these studies. We have published over 50 peer review papers over the last 5 years and attracted over £6m in grant funding. CNS Imaging and Autonomic neuropathy We have demonstrated uniquely, spinal cord atrophy in the neuropathic process and found that this process is early, found even in those with sub clinical (early) neuropathy. We have recently reported the involvement of the brain by demonstrating: a) the presence of thalamic neuronal dysfunction in DPN using MR Spectroscopy, and b) impaired thalamic blood flow in those with painless DPN and increased thalamic vascularity in those with painful DPN by using MR perfusion imaging. Cardiac autonomic neuropathy (CAN) is a serious complication of diabetes and carries up to a five-fold increased risk of mortality. We have developed a simple test 5 min test for subclinical CAN, based on Spectral Analysis of Heart Rate Variability which may allow the identification of high risk subjects. This test also was found to differentiate patients with painful from painless diabetic neuropathy. We have published over 40 peer reviewed papers in the last 5 years and generated >£1m of grant funding. Endocrine hormone replacement and treatment of hormone excess. We have developed new therapies for adrenal insufficiency including congenital adrenal hyperplasia, developing chronocort a new modified release formulation of hydrocortisone. We have obtained orphan drug designation for chronocort. We have established University of Sheffield spin out company Diurnal Ltd to develop chronocort in collaboration with the University of Sheffield. Obtained 5.6 million euro framework 7 EU grant to develop neonatal infant preparation of hydrocortisone (infacort) as principle investigator and the University of Sheffield as co-ordinator of the study. We have recently initiated a study in testosterone replacement in young male cancer survivors (TRYMS). We have developed a long acting growth hormone agonist and antagonist, currently in preclinical phase with expectation of phase 1 clinical studies in 2013 backed by a University spin out company Asterion Ltd that has over 25 granted patents in this area. We have developed a novel strategy to treat Cushing’s disease using siRNA for which orphan drug designation has been granted from EMA. We are developing a translational research partnership (TRP) with nine other major UK centres. We have published over 40 peer reviewed papers in the last 5 years and attracted >£5million grant funding. Infrastructure We are currently supported by two research nurses and two part time administrators. We are currently advertising for a Research Coordinator to support writing of research applications and helping investigators in the Dept to guide projects through the research process and ensure that studies are undertaken to a high quality. Experimental Medicine Research Strategy in Theme X 2012-2017 Short, medium and long term plans Hypoglycaemia and Type 1 diabetes studies (Prof Simon Heller) 1. Pathophysiology of insulin induced hypoglycaemia a. We have funding in place to study basic potential mechanisms (electrophysiological, inflammatory, rheological) of mortality in individuals with Type 2 diabetes using an experimental human model (hyperinsulinaemic 2 2. 3. 4. 5. glucose clamp) and ambulatory studies involving continuous glucose monitoring and ambulatory ECGs. b. We are also currently undertaking EM studies exploring the contribution of autonomic neuropathy to hypoglycaemia unawareness and the responses of the autonomic nervous system during experimental hypoglycaemia. We are planning EM studies to supplement an epidemiological survey measuring the pathophysiological responses of first degree relatives of victims of the dead in bed syndrome in those with Type 1 diabetes. We are currently engaged in a Hypo-Compass trial (multicentre, funded by Diabetes UK) in which patients with hypoglycaemia unawareness are randomised to continuous glucose monitoring, pump therapy or education. In a sub study funded within the grant we are exploring the effect of autonomic neuropathy which requires additional glucose clamping in patients with unawareness, Type 1 diabetic controls and non-diabetic controls. We are funded by a Diabetes UK grant in a multicentre study to undertake the first ambulatory trial of a closed loop device and insulin pump designed to control blood glucose automatically in adults with Type 1 diabetes (ANGELA 3). This will involve assessment and monitoring (including overnight stays in the CRF) before a period of ambulatory evaluation in patients who take the device home. Studies in newly diagnosed Type 1 diabetes We are anticipating being the lead UK site (in collaboration with Dr John Snowdon the Dept of Haemato-oncology) of myelosupressive therapy and autologous bone marrow transplantation in an attempt to maintain insulin secretion and insulin independence in newly diagnosed patients with Type 1 diabetes. We are also co-applicants on an application to HTA proposing a trial of a GLP-1 analogue in newly diagnosed individuals with Type 1 diabetes. This tests the hypothesis that such agents will maintain both endogenous insulin and the glucagon response to hypoglycaemia. 1. CNS Imaging and diabetes (Prof Solomon Tesfaye) In a 5 year program grant we now want to determine: 1) the microvascular perfusion characteristics of the thalamus and other areas of the pain matrix in type 1 diabetic subjects with painful diabetic neuropathy, both at the resting state and in response to acute pain, and 2) the effect of improvement in the intensity of painful symptoms on microvascular perfusion of the thalamus and other areas of the pain matrix in subjects with painful diabetic neuropathy and 3)the effect of improvement in the intensity of painful symptoms on fMRI correlates of painful diabetic neuropathy. The proposed work will be the first one to initiate entirely novel studies that will identify objective, perfusion and fMRI correlates of pain in diabetes with great potential for the development of new and more effective analgesic compounds that specifically target key pathological correlates of painful diabetic neuropathy. We are taking a lead in this proposal that will also include investigators from the Mayo Clinic (Prof PJ Dyck) and University of Oxford FMRIB (Prof I Tracey). 2. Biomarkers of diabetic autonomic neuropathy (Prof Solomon Tesfaye) 3 The main aims of our 5-year, multi-centre, prospective study are to: 1) determine the concurrent validity of SHRV as a sensitive biomarker of early (subclinical) CAN in a cross-sectional study, 2) determine the predictive validity of SHRV as a biomarker of the future development of established CAN in a prospective study and 3) determine if intensive, multi-factorial intervention including the use of a novel statin/ fenofibrate combination prevents the development of established CAN. On the basis of current CAN Gold standards baroreceptor sensitivity test (BRS) and AFTs, age and sex matched type 1 patients will be allocated to groups with: 1) no CAN with normal BRS and AFTs, 2) subclinical CAN with abnormal BRS but normal AFTs and 3) established CAN with abnormal BRS and AFTs. The ability of SHRV to diagnose subclinical CAN will be tested. A group of matched healthy volunteers will also be recruited for comparison. These 4 groups will be followed for 3 years. The ability of SHRV to predict the development of established CAN will be tested in the prospective study. A subsection of subjects with subclinical CAN will undergo intensive multi-factorial treatment for a period of 3 years. Thus the proposal will simultaneously interrogate if a simple test can identify high risk diabetic subjects for CAN and if such patients can benefit from a novel, intensive multi-factorial therapy, and may have a major impact for the screening and management of CAN in diabetic patients. Endocrinology (Prof Richard Ross, Dr John Newell-Price) The main goal is to translate new endocrine therapies into commercial products by 2017 these include: 1. Chronocort for the treatment of congenital adrenal hyperplasia and adrenal insufficiency. 2. Infacort for the treatment of neonatal and infant congenital adrenal hyperplasia and adrenal insufficiency. 3. High dose vitamin D for the replacement of vitamin D deficiency – Innovation opportunity with D3 Pharma. 4. Glucocorticoid antagonists for the treatment of sub clinical Cushing’s disease and as a diagnostic test to stratify patients with functioning adrenal incidentalomas. 5. siRNA as therapy for Cushing’s disease How will the CRF facilitate this strategy The CRF will be crucial to conducting the detailed physiological studies described in this document. These include the detailed physiological studies involving glucose clamps and measurements of autonomic function. The imaging studies are generally conducted in the academic dept of radiology which is where the MRI facilities are housed. However, where research nurses are needed to support this work, these can be provided either from the CRF research nurse complement or those research nurses who although based in the Diabetes/Endocrine Dept, work under the auspices of the CRF. The CRF will be crucial to the first in man studies of siRNA therapy. Phase 1, 2 and 3 studies for chronocort, infacort, vitamin D and glucocorticoid antagonists will also be undertaken in the CRF. 4 Markers of esteem Simon Heller Chairman – Clinical Studies Advisory Committee, Diabetes Research Network Member – Diabetes UK Research Committee Member of Diabetes UK Scientific and Research Advisory Group Member of HTA Member of Juvenile Diabetes Foundation International, UK Advisory Committee Solomon Tesfaye: Chairman – Neurodiab (largest global neuropathy study group) 2006- 2009 Chairman - International Expert Group on Diabetic Neuropathy 2009Vice Chairman - Science and Research Committee of Diabetes UK 2010External reviewer of the NICE guidelines for management of diabetic neuropathies (2008) and committee member for the neuropathic pain panel in 2010 Executive Committee member of the UK Neuropathy Trust 2004Member of Global Quantitative Sensation Testing Society; Sets Global Standards 2005-To date. www.qst-s.org Trustee of International Insulin Foundation (IIF) http://www.access2insulin.org/ 2007-To date Associate Editor of Diabetologia 2001-2003 (Journal of the European Association for the Study of Diabetes).
