Personal DetailsXiaoyu Yan received his Bachelor’s and Master’s degree from Shenyang Pharmaceutical University, China. He also received a Master’s degree in pharmaceutical sciences from University of Saskatchewan, Canada. He obtained his PhD in 2012 from Department of Pharmaceutical Sciences, University at Buffalo (SUNY). After his PhD, he worked as a clinical pharmacometrician/pharmacologist at Janssen Research & Development (Johnson & Johnson) and Regeneron Pharmaceuticals, USA.
During his time in pharmaceutical industry, Xiaoyu applied model informed drug development approaches to help the development team not only better understand disease and target, but also find the right dose for the right patient at right time. He has contributed to the global approval of several new therapies for diseases in various areas, such as oncology, immunology, cardiovascular, and neuroscience.
Xiaoyu joined the School of Pharmacy at the Chinese University of Hong Kong in September 2018. His research interests are focused on the pharmacokinetics and pharmacodynamics of therapeutic biologics, and utilization of modeling and simulation approaches to optimize drug therapy and develop new treatment strategy.
***Xiaoyu’s group has openings for postdoctoral fellows, MPhil/PhD students, research assistants, visiting scholars. Candidates with a background in relative areas (biochemistry/molecular biology, pharmacology, cell biology, immunology, biochemical engineering, drug metabolism and pharmacokinetics, mathematics, statistics or other field related) are welcome to apply. Please contact Dr. Yan (xiaoyuyan@cuhk.edu.hk) for more information.***
ResearchResearch InterestsXiaoyu’s current research is focused on the development of new therapies for anemic patients demonstrating resistance to erythropoiesis-stimulating agents (ESAs). ESAs is a class of therapeutic proteins functioning as erythropoietin receptor (EPOR) agonists. They stimulate the production of red blood cells by binding to EPOR on erythroid cells in bone marrow, and stimulate their proliferation and differentiation.
ESAs has transformed the way of managing the anemia in patients with chronic kidney disease (CKD), who may need blood transfusion otherwise. Recombinant human erythropoietin (rHuEPO) is the first approved ESA by US FDA in 1989 to treat anemia associated with CKD. However, up to 10% of anemic patients failed to show a satisfactory response to rHuEPO, and still require blood transfusion eventually. This phenomenon was named EPO resistance. The EPO resistance is also associated with increased risk of death or cardiovascular events.
Xiaoyu’s previous work suggested the rHuEPO treatment can induce erythroid precursor pool depletion, which may contribute to EPO resistance. Accordingly, his current work is to further the understanding role of precursor depletion in EPO resistance, and look for new therapeutic strategy that may alleviate rHuEPO induced precursor depletion. This work may provide new treatment option for anemic patients showing EPO resistance, and reducetheirtransfusion burden.
