HEPLISAV-B
HEPLISAV-B Valuable Product Approaching Approval HEPLISAV-B combines proprietary TLR 9 agonist (1018) with HBsAg to prevent hepatitis B infection in adults Path to approval in the US FDA recognizes immunogenicity of vaccine, but wants more safety data Complete enrollment of final study in 2014 to support approval Commercial Opportunity Addresses multiple areas of unmet need for adult vaccination against hepatitis B US market expected to grow to $600M Dynavax has all commercial rights Page 5
HEPLISAV-B Final Study for Approval in the US 5,500 HEPLISAV subjects and 2,750 Engerix-B subjects All HEPLISAV subjects to be followed for safety for 1 year after last active dose All potential autoimmune events will be adjudicated by an external panel of experts Subset analysis of immunogenicity in diabetic patients planned to support commercial opportunity Enrollment targeted to be complete by end of 2014 Last patient out by end of 2015 BLA amendment with a 6 month review, approval by end of 2016 Page 6
Hepatitis B Vaccination Room for Improvement Rate of protection Current vaccines provide lower rate of protection for certain segments of those at risk of infection Time to protection Current 3 dose regimen over 6 months leaves patients exposed to infection Compliance In Managed Care Organization approximately 54% of patients complete the series within 1 year from first dose 1 Compliance is lower for vaccines administered in STD clinics ~45-55% of patients receive the second dose and only ~25-40% receive the third dose in a regimen 2 1 Compliance With Multiple-Dose Vaccine Schedules Among Older Children, Adolescents, and Adults: Results From a Vaccine Safety Datalink Study.
