BUSINESS UPDATES

HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted]

HEPLISAV-B vaccine is the first and only adult hepatitis B vaccine approved in the U.S., the European Union and Great Britain that enables series completion with only two doses in one month. Hepatitis B vaccination is universally recommended for adults aged 19-59 in the U.S.

• HEPLISAV-B achieved net product revenue of $56.4 million for the second quarter of 2023, an increase of 73% compared to $32.7 million for the second quarter of 2022.
• HEPLISAV-B total market share increased to approximately 39%, compared to approximately 32% at the end of the second quarter of 2022.
• HEPLISAV-B market share in the Integrated Delivery Networks (IDNs) and Clinics segment was approximately 53% at the end of the second quarter of 2023, compared to approximately 39% for the same quarter in 2022.
• HEPLISAV-B maintained a strong market share of 45% in the retail segment at the end of the second quarter of 2023, compared to 46% for the same quarter in 2022.
• The U.S. Food and Drug Administration (FDA) recently accepted the supplemental Biologics License Application (sBLA) for HEPLISAV-B vaccination of adults on hemodialysis with a Prescription Drug User Fee Act (PDUFA) action date of May 13, 2024.
• Driven by the Centers for Disease Control and Prevention's Advisory Committee of Immunization Practices (ACIP) universal recommendation for adult hepatitis B vaccination, Dynavax continues to see the expansion of the hepatitis B vaccine market and believes HEPLISAV-B has the potential to expand the U.S. market to over $800 million by 2027, with HEPLISAV-B well-positioned to achieve a majority market share.

Clinical Pipeline
Dynavax is advancing a pipeline of differentiated product candidates that leverage its CpG 1018® adjuvant, which has demonstrated its ability to enhance the immune response with a favorable tolerability profile in a wide range of clinical trials and real-world commercial use.

Shingles vaccine program:
Z-1018 is an investigational vaccine candidate being developed for the prevention of shingles in adults aged 50 and older.

• In June, Dynavax presented results from a Phase 1 randomized, active-controlled, dose escalation, multicenter trial to evaluate the safety, tolerability, and immunogenicity of Z-1018, at the National Foundation for Infectious Diseases' 2023 Annual Conference on Vaccinology Research. These results demonstrate the opportunity to develop a shingles vaccine with improved vaccine tolerability and comparable efficacy to Shingrix and support the continued development of Dynavax's shingles vaccine candidate.
• In the second half of 2023, Dynavax plans to assess the regulatory pathway with the FDA to support the initiation of a Phase 1/2 trial in early 2024.

Tdap vaccine program:
Tdap-1018 is an investigational vaccine candidate intended for active booster immunization against tetanus, diphtheria, and pertussis (Tdap).

• Dynavax recently completed a pertussis challenge study in nonhuman primates demonstrating protection from disease upon challenge and robust Type 1 T helper (Th1) cell responses in nonhuman primates vaccinated with Tdap-1018.
• The Company recently received Type B meeting feedback from the FDA on the Tdap-1018 clinical development plan and plans to submit an Investigational New Drug Application (IND) to the FDA in the fourth quarter of 2023 to support the initiation of a human challenge study.

Plague vaccine program:
DV2-PLG-01 is a plague (rF1V) vaccine candidate currently in a Phase 2 clinical trial in collaboration with, and fully funded by, the U.S. Department of Defense.

• Earlier this year, the Company completed enrollment in Part 2 of the Phase 2 clinical trial, with top line data anticipated in 2024.
• In July, Dynavax and the U.S. Department of Defense executed a contract modification to support advancement into a nonhuman primate challenge study, with the agreement now totaling $33.7 million through 2025.

Cost of Sales - Product. Total cost of sales – product for the second quarter of 2023 decreased to $13.5 million, compared to $83.4 million in the second quarter of 2022.

Cost of sales - product for HEPLISAV-B in the second quarter of 2023 increased to $13.5 million, compared to $10.3 million for the second quarter of 2022.
