GlobeImmune Announces Top Line Results From GS-4774 Phase 2 Trial in Virally-Suppressed Chronic HBV Patients

LOUISVILLE, CO–(Marketwired – May 27, 2015) – GlobeImmune, Inc. (NASDAQ: GBIM) today announced top line results from the GS-4774 Phase 2 study in patients with chronic hepatitis B on long term viral suppression with an oral antiviral treatment. In this study, patients treated with the highest dose of GS-4774 plus ongoing oral antiviral therapy (OAV) did not show a reduction in hepatitis B surface antigen (HBsAg) at week 24, the primary endpoint of the study, but at 48 weeks had a mean -0.17 log10 reduction of HBsAg compared with a -0.04 log10 reduction in the OAV alone group (p=not significant). Three patients receiving the highest dose of GS-4774 had HBsAg reductions between -0.94 and -3.89 log10 at 48 weeks. There was no difference in HBsAg reductions between the two lowest dose groups versus the control arm at 48 weeks. Further characterization of the T cell response to GS-4774 and association with HBsAg changes are ongoing.
