MedicalResearch.com Interview with: Dr. Eli Hatchwell, MA MB BChir (Cantab) DPhil (Oxon) BA (OU) Chief Scientific Officer Population Bio UK, Inc. Begbroke Science Park Begbroke Hill Begbroke, Oxfordshire United Kingdom MedicalResearch.com: What is the background for this study? Response: Progressive Multifocal Leukoencephalopathy (PML) is a devastating condition that is associated with a number of clinical situations, including treatment with a variety of drugs. Of these, the best known is natalizumab (Tysabri), which is a very successful drug in the treatment of MS (multiple sclerosis). Only a small proportion of patients treated with natalizumab develop PML and this has always been a mystery. The study was based on a hypothesis that some individuals have an underlying susceptibility to developing PML, based on the presence of variants in genes that are important in the immune system. The study identified several of these variants. (more…)

MedicalResearch.com Interview with: Marcus Koch MD PhD Associate Professor of Neurology Multiple Sclerosis Program University of Calgary MedicalResearch.com: What is the background for this study? Response: Primary progressive multiple sclerosis (PPMS) is the least common, but also the least treatable form of multiple sclerosis. PPMS does not react well to commonly used MS treatments. We believe that this is at least in part because PPMS is driven by other disease mechanisms. One disease mechanism that we believe is important in PPMS is microglial activation. Microglial cells are a type of cell in the brain and spinal cord that normally have beneficial functions, such as clearing debris or assisting repair after injury. In PPMS however, microglial cells are chronically active, and we believe that this chronic microglial activation contributes to tissue damage. (more…)
