"In 2023, we delivered a record year of revenue for HEPLISAV-B, driven by the expansion of the adult hepatitis B vaccine market in the U.S., and our team’s progress toward establishing HEPLISAV-B as the market leading vaccine. We are extremely pleased with our market share growth in the fourth quarter, which enabled us to achieve our increased product revenue guidance for the year despite the impact of expected seasonality due to increased focus on respiratory disease vaccines during the fall and winter seasons. We believe the seasonal market decline for adult hepatitis B vaccines will be limited to the fourth quarter in line with the administration of the vast majority of influenza and COVID-19 vaccines," said Ryan Spencer, Chief Executive Officer of Dynavax. "Turning to this year, we believe HEPLISAV-B is well-positioned entering 2024, supported by significant market share gains in the total market and in key market segments. We remain extremely confident in the long-term growth of the hepatitis B market, with HEPLISAV-B expected to achieve a majority market share in the U.S. In addition to HEPLISAV-B, we continue to advance our pipeline of innovative vaccine candidates and continue to pursue strategic opportunities to accelerate our growth."

Expected Commercial and Pipeline Milestones

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.

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 expect the adult hepatitis B vaccine market in the U.S. to expand at an annual growth rate of approximately 10 – 15% over the next several years to a total market of approximately $800 million by 2027, one of the largest adult vaccine markets in the U.S., with HEPLISAV-B well-positioned to achieve a majority market share.
A supplemental Biologic License Application (sBLA) for HEPLISAV-B vaccination of adults on hemodialysis is currently under priority review by the U.S. Food and Drug Administration (FDA) with a Prescription Drug User Fee Act (PDUFA) action date planned for May 13, 2024.
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.

Dynavax expects to submit an Investigational New Drug Application (IND) to the FDA to support initiation of a Phase 1/2 trial of Z-1018 in the first half of 2024.
Tdap vaccine program:
Tdap-1018 is an investigational vaccine candidate intended for active booster immunization against tetanus, diphtheria, and pertussis (Tdap).

Dynavax plans to submit an IND to the FDA to support the initiation of a Phase 2 human challenge study of Tdap-1018 in the second half of 2024, upon completion of the independent study conducted by the Canadian Center for Virology to establish the human challenge dose.
Plague vaccine program:
Dynavax is developing a plague (rF1V) vaccine candidate adjuvanted with CpG 1018 currently in a Phase 2 clinical trial in collaboration with, and fully funded by, the U.S. Department of Defense.

Dynavax anticipates top line data for the randomized, active-controlled Phase 2 clinical trial evaluating immunogenicity, safety, and tolerability of the plague vaccine candidate in 2024.

Important U.S. Safety Information (ISI)
Do not administer HEPLISAV-B to individuals with a history of a severe allergic reaction (e.g., anaphylaxis) after a previous dose of any hepatitis B vaccine or to any component of HEPLISAV-B, including yeast.

Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of HEPLISAV-B.

Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to HEPLISAV-B.

Hepatitis B has a long incubation period. HEPLISAV-B may not prevent hepatitis B infection in individuals who have an unrecognized hepatitis B infection at the time of vaccine administration.

The most common patient-reported adverse reactions reported within 7 days of vaccination were injection site pain (23% to 39%), fatigue (11% to 17%), and headache (8% to 17%).
