Dynavax Completes Enrollment of First Cohort of Patients in Phase 1b Clinical Trial for Hepatitis B Therapy

BERKELEY, CA--(Marketwire - November 19, 2009) - Dynavax Technologies Corporation (NASDAQ: DVAX) announced today that enrollment has been completed for the first of three cohorts of patients receiving DV-601 hepatitis B therapy in a Phase 1b clinical trial. The safety profile of patients in the first cohort met pre-specified criteria for dose escalation and the second cohort has been opened for enrollment. Dynavax expects to report top-line data from this trial in the second half of 2010. DV-601 is the first hepatitis B therapy to combine both the surface and core HBV antigens, and Dynavax has retained all commercial rights to this product.

In this open-label, dose-escalating Phase 1b trial being conducted in Europe, up to 30 patients will receive 6 injections of DV-601 over a three month period. The primary endpoints of this trial are safety and tolerability of DV-601. The secondary endpoints are immunologic and virologic measures of efficacy.
