About Tekmira

Tekmira Pharmaceuticals Corporation is a biopharmaceutical company dedicated to discovering, developing and commercializing a cure for patients suffering from chronic hepatitis B infection (HBV). Our strategy is to target the three pillars necessary to develop a curative regimen for HBV, including suppressing HBV replication within liver cells, stimulating and reactivating the body's immune system so that it can mount an effective defense against the virus and, most importantly, eliminating the reservoir of viral genomic material known as covalently closed circular DNA, or cccDNA, that is the source of HBV persistence. Our portfolio of assets includes eight drug candidates for use in combination to develop a cure for HBV, and includes our product TKM-HBV currently in Phase 1 clinical studies.

We also have a pipeline of non-HBV assets in oncology, anti-viral and metabolic therapeutics that leverage our expertise in RNA interference (RNAi) therapeutics and leading Lipid Nanoparticle (LNP) technology. RNAi and LNP technology have the potential to generate new therapeutics that take advantage of the body's own natural processes to silence disease causing genes, or more specifically, to eliminate specific gene-products, from the cell. We intend to maximize the value of our non-HBV assets in the clinic, namely: TKM-PLK1 for advanced gastrointestinal neuroendocrine tumors, adrenocortical carcinoma and hepatocellular carcinoma; and TKM-Ebola, and TKM-Ebola-Guinea for ebola virus disease; as well as our preclinical programs in metabolic disorders and filoviruses.

Tekmira is headquartered in Vancouver, BC, Canada with offices in Doylestown, PA, USA. For more information, visit www.tekmira.com.
