• HEPLISAV-B® vaccine net product revenue grew 10% year-over-year to approximately $48 million in the first quarter of 2024
• Reaffirming full year 2024 HEPLISAV-B net product revenue guidance of $265 - $280 million

EMERYVILLE, Calif., May 8, 2024 /PRNewswire/ -- Dynavax Technologies Corporation (Nasdaq: DVAX), a commercial-stage biopharmaceutical company developing and commercializing innovative vaccines, today reported financial results and provided a business update for the quarter ended March 31, 2024.

"The first quarter of 2024 saw continued year-over-year growth in quarterly HEPLISAV-B net product revenue. As we expected, growth in the U.S. hepatitis B vaccine market was slightly down during the first quarter compared to the fourth quarter due to an extended cough, cold and flu season which reduced the number of vaccination opportunities – a dynamic observed across other non-respiratory vaccine markets beyond hepatitis B. Despite this start to the year, we remain very encouraged about the hepatitis B market opportunity, both in 2024 and longer term. We are now seeing a pickup in the market as providers have begun to shift to non-respiratory vaccine campaigns in recent weeks, our retail pharmacy partners are expected to meet their demand expectations for this year, and several top IDN systems are planning to launch new hepatitis B focused initiatives. The U.S. adult hepatitis B vaccine opportunity remains significant with over 130 million patients eligible, one of the largest addressable patient populations in the U.S., and the vast majority remaining unvaccinated," said Ryan Spencer, Chief Executive Officer of Dynavax.

"We're also excited for several upcoming milestones from our novel vaccine pipeline, including the planned initiation of a mid-stage clinical trial in shingles this year, and data readouts from our plague and shingles vaccine programs expected across 2024 and 2025. In addition to this continued execution, and bolstered by our strong financial position, we continue to evaluate strategic opportunities to accelerate growth and further diversify our portfolio."

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 vaccine achieved net product revenue of $47.8 million for the first quarter of 2024, an increase of 10% compared to $43.5 million for the first quarter of 2023.
• HEPLISAV-B total estimated market share in the U.S. increased to approximately 41%, compared to approximately 37% at the end of the first quarter 2023.
• HEPLISAV-B estimated market share in the retail pharmacy segment increased to approximately 55%, compared to approximately 49% at the end of the first quarter of 2023.
• HEPLISAV-B estimated market share in the Integrated Delivery Networks (IDNs) and Large Clinics segment increased to approximately 55%, compared to approximately 49% at the end of the first quarter 2023.
• A supplemental Biologic License Application (sBLA) for HEPLISAV-B vaccination of adults on hemodialysis is currently under 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.
• Driven by the Centers for Disease Control and Prevention's Advisory Committee of Immunization Practices (ACIP) universal recommendation for adult hepatitis B vaccination, the hepatitis B vaccine market continues to expand in the U.S. and Dynavax believes the U.S. market has the potential to grow 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 years and older.

• In March 2024, Dynavax received clearance of its Investigational New Drug Application (IND) by the U.S. FDA for its novel shingles vaccine program, Z-1018.
• Dynavax plans to initiate a randomized, active-controlled, dose escalation, multicenter Phase 1/2 trial to evaluate the safety, tolerability, and immunogenicity of Z-1018 compared to Shingrix® in approximately 440 healthy adults aged 50 to 69.
• Dynavax plans to initiate the Phase 1/2 trial in the second quarter of 2024 and expects to report top line immunogenicity and safety data in the second half of 2025.

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

• Prior to advancing Tdap-1018 into a previously announced Phase 2 human challenge trial, Dynavax plans to evaluate the persistence of pertussis immunogenicity of Tdap-1018 through a long-term follow-up study of participants that completed a Phase 1 trial of a booster dose of Tdap-1018 compared to an active control.
• The extension study is expected to follow participants for up to approximately three years following initial vaccination. Top line results from the Phase 1 extension study are expected in the fourth quarter of 2024.

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.

• In March 2024, Dynavax and the U.S. Department of Defense executed a contract modification to add approximately $4 million to support CMC work for the plague vaccine candidate, with the agreement now totaling $38 million through 2025.
• Dynavax anticipates top line data from both the randomized, active-controlled Phase 2 clinical trial evaluating immunogenicity, safety, and tolerability, as well as the nonhuman primate challenge study of the plague vaccine candidate, in the fourth quarter of 2024.

FIRST QUARTER 2024 FINANCIAL HIGHLIGHTS

Total Revenues and Net Product Revenue.

• Total revenues for the first quarter of 2024 were $50.8 million, compared to $46.9 million for the first quarter of 2023.
• HEPLISAV-B vaccine net product revenue was $47.8 million for the first quarter of 2024, compared to $43.5 million for the first quarter of 2023.
• Other revenue was $2.9 million for the first quarter of 2024, compared to $3.5 million for the first quarter of 2023. Other revenue primarily includes revenue from the plague vaccine agreement with the U.S. Department of Defense.

Cost of Sales - Product. Cost of sales - product for HEPLISAV-B the first quarter of 2024 decreased to $11.0 million, compared to $14.7 million for the first quarter of 2023. The decrease was primarily due to lower per-unit manufacturing costs as the result of previous process improvements, partially offset by a $1.3 million inventory write-off charge recorded during the first quarter of 2024.

Research and Development Expenses (R&D). R&D expenses for the first quarter of 2024 decreased to $13.5 million, compared to $13.6 million for the first quarter of 2023. The decrease was primarily driven by the timing of clinical development costs due to the completion of clinical trials in early 2023 and activities for planned clinical trials in 2024, partially offset by increases related to investments in our CpG 1018 preclinical and clinical collaborations.

Selling, General, and Administrative Expenses (SG&A). SG&A expenses for the first quarter of 2024 increased to $44.1 million, compared to $36.5 million for the first quarter of 2023. The increase was primarily driven by increased headcount and other investments supporting our strategic growth, including an overall increase in targeted commercial and marketing efforts designed to increase HEPLISAV-B market share and maximize the opportunities presented by the ACIP's universal recommendation.

Net Loss. GAAP net loss was $8.7 million, or $0.07 per share (basic and diluted) in the first quarter of 2024, compared to GAAP net loss of $24.3 million, or $0.19 per share (basic and diluted) in the first quarter of 2023.

Cash and Marketable Securities. Cash, cash equivalents and marketable securities were $723.5 million as of March 31, 2024.
