Clinical Pharmacology
UTE SCHWARZ, PhD, Assistant Professor

Dr. Schwarz is an Assistant Professor in the Division of Clinical Pharmacology, Department of Medicine and Department of Physiology & Pharmacology. She received her medical degree at the Technical University Dresden, Germany in 1995, and received her accreditation in Clinical Pharmacology from the Saechsische Aerztekammer, Dresden, Germany in 2003.

She completed a postdoctoral fellowship in Clinical Pharmacology at Vanderbilt University in Nashville, USA (1999-2000), and joined the Division of Clinical Pharmacology, Department of Medicine, at Vanderbilt University as a junior faculty member in 2004. In 2012, Dr. Schwarz completed her Ph.D. graduate training in Pharmacology & Toxicology at the University of Western Ontario under the supervision of Dr. Richard Kim.

In 2005, she was awarded the Presidential Trainee Award by the American Society for Clinical Pharmacology and Therapeutics (ASCPT), and was recipient of a Western Graduate Research Scholarship in Pharmacology & Toxicology, University of Western Ontario (2007 - 2012).

Within the Personalized Medicine Program, her translational research pursues studies evaluating genetic and environmental factors that influence variation in drug exposure, therapeutic response, and toxicity in adult and pediatric patient populations with focus on drug metabolizing enzymes and drug transporters. Specifically, Dr. Schwarz’s research is focused on better understanding interpatient variability in blood exposure and adverse effects of direct oral anticoagulants (also DOACs), a new class of medications prescribed in patients with atrial fibrillation to prevent strokes. Her collaborative research in the area of oncology aims to discover and apply pharmacogenetic factors that can better predict the therapeutic and/or adverse drug responses of the chemotherapeutic agents 5-fluorouracil and tamoxifen in patients with colorectal and breast cancer (Collaboration Dr. Richard Kim). Other studies evaluate if genotype-guided dosing of mercaptopurine in children with acute lymphoblastic leukemia (ALL) prevents severe bone marrow toxicity and if genetic markers and blood exposure of methotrexate predict renal toxicity in pediatric ALL. Another area of interest relates to how genetic factors may help optimize the prescribing of anti-nausea medications for children undergoing cancer therapy (Collaboration Dr. Alexandra Zorzi). A current project applies cell-based and transgenic mouse models as well as a clinical study in subjects at high risk for type 2 diabetes to investigate underlying mechanisms of statin-induced impaired beta cell function involving drug transport. To aid in the discovery of novel pharmacogenetic predictors, Dr. Schwarz has been leading the development and validation of a next-generation gene sequencing strategy targeting exomes of 100 drug metabolizing enzymes, transporters, and drug targets.

She is a member of several Professional organizations, including the Canadian Society of Pharmacology and Therapeutics (CSPT) and the International Society for the Study of Xenobiotics (ISSX).

Critical Care Medicine
MARAT SLESSAREV, MD, MSc, FRCPC, Assistant Professor

Dr. Marat Slessarev is a clinician-scientist in the Division of Critical Care. He completed his HonBSc, MD, MSc in Physiology and post-graduate training in Internal Medicine at the University of Toronto, followed by fellowship in adult Critical Care Medicine and a PhD in Medical Biophysics at Western University. Dr Slessarev works as a Consultant Intensivist at Critical Care Trauma Centre and Medical Surgical Intensive Care Unit at LHSC and as a Regional Medical Lead (Donation) at Ontario Health (Trillium Gift of Life Network). His research is focused on clinical innovation at the intersection of neurosciences, critical care and organ donation.

He co-leads the following studies/programs of research:

1) NeuPaRT (Neurologic Physiology after Removal of Therapy) program of research seeks to measure when brain activity stops relative to circulatory arrest during the dying process after removal of life support, and interpret these findings from the ethical, legal, and policy lenses to inform the timing of death determination in deceased organ donation;

2) SAVE program of research (https://saveicu.com) that seeks to advance sedation practices in critical care, in part through its flagship SAVE-ICU RCT - a pragmatic open-label multicentre trial comparing the effect of sedation with inhaled (intervention) vs IV (control) sedatives on patient (mortality, quality of life) and health system (duration of ventilation, ICU stay) outcomes in patients with respiratory failure; and

3) ABOVE (Advancing Brain Outcomes in pediatric critically ill patients sedated with Volatile AnEsthestic Agents) - a pilot multicentre RCT assessing if sedation with inhaled anesthetics vs IV sedatives improves neurocognitive outcomes in paediatric patients;

4) Normothermic Regional Perfusion (NRP) – a new intervention that reconditions donor organs after circulatory determination of death but prior to transplantation by selectively recirculating oxygenated blood to abdominal (A-NRP) or thoraco-abdominal (TA-NRP) organs. While practiced in Europe and USA, NRP has not been adopted in Canada due to concerns regarding violation of death determination criteria and potential for donor harm (via resumption of brain blood flow and sentience). Dr Slessarev co-leads provincial interdisciplinary working group that aims to address these challenges and safely implement this method in Ontario.
