(Thomson Reuters ONE via COMTEX) -- LOUISVILLE, Colo., Jan. 28, 2013 - GlobeImmune, Inc., today announced the initiation of a Phase 1a clinical trial to investigate the safety and immunogenicity of GI-13020 in healthy volunteers. The GI-13020 Tarmogen�, which GlobeImmune is developing in collaboration with Gilead Sciences, Inc., consists of whole, heat-killed, recombinant S. cerevisiae yeast genetically modified to express hepatitis B (HBV) antigens. This study is being conducted under an Investigational New Drug application (IND) that was filed with the U.S. Food and Drug Administration in December 2012. As a result of successfully filing the IND, GlobeImmune received a milestone payment from Gilead.
The GI-13020-01 Phase 1a clinical trial is a randomized, open-label, dose escalation trial assessing the safety, tolerability and immunogenicity of various doses of GI-13020 in healthy adults. This study is designed to enroll 48 evaluable subjects at a single U.S. center.
"While approved anti-viral drugs have been shown to effectively suppress replication of the hepatitis B virus, they rarely result in cures and must be taken indefinitely," said David Apelian, M.D., Ph.D., Chief Medical Officer at GlobeImmune. "GI-13020 is designed to activate an antigen-specific immune response against HBV, and our development strategy will be to combine GI-13020 with direct-acting antiviral medicines to determine if the combination can increase rates of surface antigen seroconversion, thereby leading to a cure for infected patients."
