Press Release Details

EMERYVILLE, Calif., May 6, 2021 /PRNewswire/ -- Dynavax Technologies Corporation (Nasdaq: DVAX), a biopharmaceutical company focused on developing and commercializing novel vaccines, today reported financial results for the first quarter of 2021.

"The first quarter of 2021 continued to build on our successful execution in 2020. With the combined strength of opportunities from HEPLISAV-B and CpG 1018, we believe 2021 will be a transformational year for Dynavax," commented Ryan Spencer, Chief Executive Officer of Dynavax. "HEPLISAV-B continues to take market share in accounts targeted by our field sales team, reaching a new high this quarter, which reinforces our belief that it will become the standard of care in the U.S. for adult hepatitis B vaccination."

Mr. Spencer continued, "Dynavax is making progress on numerous collaborations for its proven vaccine adjuvant CpG 1018 across multiple indications, including COVID-19, pertussis, and universal flu.  Our COVID-19 collaborations have advanced significantly in recent months with multiple partners targeting emergency or conditional authorization in the second half of 2021.  Importantly, these collaborations are now generating significant revenue for Dynavax, with first quarter CpG 1018 revenue of $74.6 million. Additionally, last week we expanded our agreement with CEPI whereby they fund manufacturing of CpG 1018 for future sales to CEPI grantees, providing the opportunity for additional revenue in 2021 from COVID-19 collaborations. The emerging portfolio of product opportunities with CpG 1018 has the potential to drive significant revenue growth beyond this year."

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

• Net product revenue for HEPLISAV-B during the first quarter 2021 was $8.3 million compared to $10.5 million for the first quarter 2020, driven by increased market share offset by a reduction in vaccine utilization due to the COVID-19 pandemic.
• Market share in accounts targeted by the field sales team increased to 27%, up from 21% market share in the first quarter of 2020.
• Final immunogenicity and interim safety results of the ongoing clinical trial (HBV-24) evaluating HEPLISAV-B in patients undergoing hemodialysis evaluating a new 4-dose regimen of HEPLISAV-B demonstrated a seroprotection rate of 89.3%.  Interim safety data showed HEPLISAV-B is well tolerated and no safety concerns were observed. Full safety data are expected by the end of 2021.
• Positive results from the post-marketing observational surveillance study (HBV-25) in over 69,000 patients demonstrated the study met the primary endpoint and showed no evidence of an increased risk of acute myocardial infarction associated with vaccination with HEPLISAV-B compared to Engerix-B.

CpG 1018 (Advanced Vaccine Adjuvant)

• Net product revenue for CpG 1018 during the first quarter 2021 was $74.6 million.
• In February, Dynavax initiated a Phase 1 clinical trial of Tdap-1018, its tetanus, diphtheria, and acellular pertussis (Tdap) booster vaccine product candidate adjuvanted with CpG 1018.
• In March, Clover Biopharmaceuticals dosed the first participant in SPECTRA, a global Phase 2/3 clinical trial for its trimeric SARS-CoV 2 spike (S) protein vaccine adjuvanted with CpG 1018.
• In April, Valneva reported positive initial results for Part A of the Phase 1/2 clinical trial  of its VLA2001 COVID-19 vaccine candidate adjuvanted with CpG 1018 and subsequently initiated a pivotal Phase 3 clinical trial.
• In April, Medigen published positive Phase 1 clinical study data demonstrating neutralizing antibody titers 1.8 to 3.9 times that of human convalescent sera for its COVID-19 vaccine candidate adjuvanted with CpG 1018 and has completed enrollment of over 4,000 participants in its on-going Phase 2 clinical trial.
• In April, CEPI expanded its agreement with the Company to provide funding to manufacture CpG 1018 for its COVID-19 vaccine grantees, increasing total funding under the loan agreement from $99 million to $176 million.

2021 Milestones

• Multiple data readouts from our CpG 1018 COVID-19 collaboration partners throughout the year
• Data from the ongoing Phase 1 clinical trial of Tdap-1018 in the fourth quarter
• Launch HEPLISAV-B in the EU in the fourth quarter

Financial Results
Total Revenue. Total revenues for the first quarter of 2021 were $83.3 million, including $82.9 million of net product revenue, an increase from total revenue for the first quarter of 2020 of $10.9 million.

Product Revenue, Net. HEPLISAV-B product revenue, net was $8.3 million in the first quarter of 2021 compared to $10.5 million in the same period in 2020. CpG 1018 product revenue, net was $74.6 million in the first quarter of 2021 compared to $0.0 million in the same period in 2020.

Cost of Sales - Product. Cost of sales - product for the first quarter 2021 increased to $24.6 million, compared to $2.4 million for the first quarter of 2020. The increase was primarily due to manufacturing costs for CpG 1018.

Research and Development Expenses (R&D). R&D expenses for the first quarter of 2021 increased to $7.8 million, compared to $4.7 million for the first quarter of 2020. The increase is primarily due to development activities related to process improvements at our Dusseldorf facility and higher headcount, partially offset by a decrease in business travel due to COVID-19 travel restrictions. In addition, non-cash stock-based compensation in the first quarter of 2020 included reversal of expenses related to cancellation of certain equity grants.

Selling, General and Administrative Expenses (SG&A). SG&A expenses for the first quarter of 2021 increased to $22.4 million, compared to $20.9 million for the first quarter of 2020. Compensation and related personnel costs increased due to higher headcount and an accrual of benefits for a former executive in connection with his retirement, offset by the decrease in business travel due to COVID-19 travel restrictions.  Non-cash stock-based compensation increased due to higher headcount.

Income from Operations and Net Income. Income from operations for the first quarter of 2021 was $28.5 million compared to a loss of $19.3 million in the first quarter of 2020. Net income for the first quarter of 2021 was $0.9 million compared to a net loss of $12.6 million for the first quarter of 2020. Basic and diluted net income per share was $0.01 for the first quarter of 2021, compared to a basic net loss of $0.15 per share and diluted net loss per share of $0.25 in the first quarter of 2020.

About Hepatitis B
Hepatitis B is a viral disease of the liver that can become chronic and lead to cirrhosis, liver cancer and death. The hepatitis B virus is 50 to 100 times more infectious than HIV,ⁱ and transmission is on the rise. There is no cure for hepatitis B, but effective vaccination can prevent the disease.

In adults, hepatitis B is spread through contact with infected blood and through unprotected sex with an infected person. The U.S. Centers for Disease Control (CDC) recommends vaccination for those at high risk for infection due to their jobs, lifestyle, living situations and travel to certain areas.ⁱⁱ Because people with diabetes are particularly vulnerable to infection, the CDC recommends vaccination for adults age 19 to 59 with diabetes as soon as possible after their diagnosis, and for people age 60 and older with diabetes at their physician's discretion.ⁱⁱⁱ Approximately 20 million U.S. adults have diabetes, and 1.5 million new cases of diabetes are diagnosed each year.^iv

About HEPLISAV-B
HEPLISAV-B is an adult hepatitis B vaccine that combines hepatitis B surface antigen with Dynavax's proprietary Toll-like Receptor (TLR) 9 agonist CpG 1018 to enhance the immune response. Dynavax has worldwide commercial rights to HEPLISAV-B.

Important U.S. Product Information
HEPLISAV-B is indicated for prevention of infection caused by all known subtypes of hepatitis B virus in adults age 18 years and older.

Safety and effectiveness of HEPLISAV-B have not been established in adults on hemodialysis.

Important U.S. Safety Information (ISI)
Do not administer HEPLISAV-B to individuals with a history of 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%).

Important EU/EEA Product Information
HEPLISAV B is indicated for active immunisation against hepatitis B virus infection (HBV) caused by all known subtypes of hepatitis B virus in adults 18 years of age and older.
The use of HEPLISAV B should be in accordance with official recommendations.
It can be expected that hepatitis D will also be prevented by immunisation with HEPLISAV B as hepatitis D (caused by the delta agent) does not occur in the absence of hepatitis B infection.

Important EU/EEA Safety information
Do not receive HEPLISAV B if you have had a sudden life-threatening, allergic reaction after receiving HEPLISAV B in the past, or if you are allergic to any of components of this vaccine, including yeast. Signs of an allergic reaction may include itchy skin, rash, shortness of breath and swelling of the face or tongue.
Appropriate medical treatment and supervision should be readily available in case of rare anaphylactic reactions following the administration of the vaccine.
The administration of HEPLISAV B should be postponed in subjects suffering from acute severe febrile illness.
Immunocompromised persons may have a diminished immune response to HEPLISAV B.
Because of the long incubation period of hepatitis B, it is possible for unrecognised HBV infection to be present at the time of immunisation. HEPLISAV B may not prevent HBV infection in such cases.
There are very limited data on the immune response to HEPLISAV B in individuals who did not mount a protective immune response to another hepatitis B vaccine.
As a precautionary measure, it is preferable to avoid the use of HEPLISAV B during pregnancy. Vaccination during pregnancy should only be performed if the risk-benefit ratio at the individual level outweighs possible risks for the fetus.
The most common patient-reported side effects reported within 7 days of vaccination were pain, swelling or redness at the injection site, feeling tired, headache, muscle aches, feeling unwell and fever.

About CpG 1018 Adjuvant
CpG 1018 is the adjuvant used in HEPLISAV-B. Dynavax developed CpG 1018 adjuvant to provide an increased vaccine immune response, which has been demonstrated in HEPLISAV-B. CpG 1018 adjuvant provides a well- developed technology and a significant safety database, potentially accelerating the development and large-scale manufacturing of a COVID-19 vaccine.
