Biography

Dr. Coffin is a clinician scientist (Full Professor with tenure 2021, Hepatology). She completed MSc using the woodchuck model of hepatitis B virus infection and MD degree at Memorial University of Newfoundland and Labrador. Dr. Coffin is an internationally recognized expert on hepatitis B and hepatitis Delta. She has served on expert review panels for the World Health Organization Essential Medicines Committee (viral hepatitis), the International Coalition to Eliminate HBV Stakeholders group, the US Centres for Disease Control and Chaired of the Education subcommittee, Hepatitis B Special Interest Group, American Association for the Study of Liver Diseases.  She has an integrated basic science - translational research program that is supported by the Canadian Institutes of Health Research (CIHR) as well as internationally competitive request for proposals (RFPs) from industry. Dr. Coffin has participated in ~30 international hepatitis B virus (HBV) Phase I-IV clinical trials  (including member of Trial Guidance and Publication committee).  She was integral in establishing the Canadian Hepatitis B Research Network that has enabled unique and well-characterized longitudinal national cohort studies and bio-repositories for HBV and hepatitis Delta virus. She is leading a multidisciplinary team at the University of Calgary using the woodchuck hepatitis virus model of hepatitis B to investigate HBV pathogenesis and test new anti-HBV therapies.

Projects

Natural History of Chronic and Occult Hepatitis B (OBI) using the Woodchuck HBV Model.

My graduate degree studies in the woodchuck hepatitis virus model of hepatitis B facilitated the recognition of occult HBV (OBI) and its epidemiological (mother-to-baby transmission) and pathogenic (liver cancer) consequences.  This training led to a lifelong interest in the study of hepatitis B virus infection.  In 2020, I was instrumental in establishing the woodchuck hepatitis virus model at the University of Calgary, followed by a second colony housed at the University of Saskatchewan, Western College of Veterinary Medicine in 2022, with assistance of veterinarians (Drs. DW Whiteside, F van der Meer, University of Calgary) and Professor Michalak. Together with Professor CN Jenne (University of Calgary), our studies involve novel imaging approaches (live cell or intravital microscopy) of living woodchuck liver during acute and chronic woodchuck hepatitis virus infection and development of hepatocellular carcinoma (liver cancer).  We are currently conducting studies assessing molecular virological outcomes and immune responses to approved and novel antiviral therapies, including treatment interruption and manipulation / study of the adaptive and innate immune response to acute and chronic hepadnaviral infection.


Pathogenesis and Natural History of Viral Hepatitis B in Pregnancy

Globally, the greatest risk of acquiring a lifelong (persistent hepatitis B infection) is from mother-to-child at birth.  Our research group has conducted studies on the clinical and virological outcomes of hepatitis B during pregnancy. Our translational studies included analysis of virus genome evolution, novel viral biomarkers and cytokine changes during pregnancy and post-partum in individuals living with hepatitis B virus infection. Additional large cohort studies showed the impact of tenofovir antiviral therapy on prevention of mother-to-child hepatitis B transmission, and the risk of post-partum virological and immunological flares after stopping antiviral treatment. Recently, our lab is also using the woodchuck hepatitis virus model to inform understanding age dependent risk of chronicity and virological and immunological factors impacting mother-to-child transmission.


Pathogenesis and Natural History of Occult and Chronic Hepatitis B in Special Patient Populations (i.e., transplant, immunocompromised, coinfection, metabolic dysfunction-associated steatotic liver disease)

My laboratory has conducted studies on the impact of hepatitis B in well-characterized clinical cohorts and special patient populations (i.e., liver transplant, HIV/HBV coinfection, hepatitis Delta).  As a clinician scientist, I have spearheaded valuable bio-banking initiatives to support this research.  Detailed molecular virological analysis of patient samples found occult HBV, hepatocellular carcinoma (liver cancer) associated variants despite antivirals in transplant recipients, and in HIV or HCV co-infection. In HBV/HIV co-infection, we found that immune cells are reservoirs for both viruses and also carry unique variants.  Recent studies include assessing the impact and pathogenesis of metabolic dysfunction associated steatotic liver disease (MASLD) for patients living with hepatitis B. This translational body of  work include cohort studies on the impact of HBV treatment on lipid profile and HCC risk, extending to analysis of unique variants in patients with more severe steatosis and HBV-specific immune responses. We have shown lower hepatitis B surface antibody responses to the approved yeast recombinant HBV surface vaccine in unvaccinated patients with more severe obesity and MASLD. This latter work has implications for vaccine development given the obesity epidemic. Finally, there are new immunological and virological biomarkers in development for hepatitis B which we are utilizing in studies of these unique cohorts in collaboration with senior scientists at the National Microbiology Laboratory (Dr C Osiowy (retired) and Dr. E Lee).


National and International Epidemiologic Cohort Studies, Clinical Trials and Novel Therapeutic Approach’s targeting Hepatitis B and/or Hepatitis Delta

I have led multisite HBV epidemiologic studies at the University of Calgary and nationally.  I was integral in forming the Canadian HBV research Network (www.canadianHBVnetwork.ca, CanHepB). The Canadian HBV Network has published important national studies on hepatitis B epidemiology, treatment outcomes, genotypes, immunology, and impact of metabolic dysfunction associated liver disease. Importantly, we recently published the largest multisite study on hepatitis Delta epidemiology and genotypes in Canada, that has been included in international cohort publications. Hepatitis Delta is an orphan disease that is understudied with limited treatment options.  Although there is a vaccine there is currently no cure for Hepatitis B. There are many new antiviral therapies in the pipeline for hepatitis B (www.hepB.org) and our research group has participated in ~40 international Phase I-IV hepatitis B clinical trials at the University of Calgary.
