"I am proud of our 2018 achievements, particularly the launch of HEPLISAV-B, which enabled us to generate revenue of $3.9 million in the fourth quarter," said Eddie Gray, chief executive officer of Dynavax. "HEPLISAV-B is the only two-dose hepatitis B vaccine, and it consistently protects more than 90% of adult patients. We are confident that it is poised to become the standard of care hepatitis B adult vaccine, and remain firm in our expectation that HEPLISAV-B operations will become profitable by the end of 2019."

Mr. Gray continued. "In immuno-oncology, we are focused on paths to approval where we believe our TLR9 technology has a competitive advantage. SD-101, in combination with pembrolizumab has consistently demonstrated response rates in melanoma and head and neck cancer that are higher than those reported for pembrolizumab alone. We are actively evaluating a number of opportunities, including partnerships, to advance SD-101 into registrational studies, and are committed to being thoughtful and diligent in determining the best path forward to drive value for our shareholders and provide better options for patients."

Immuno-oncology

SD-101

SD-101 adds meaningful clinical benefit to KEYTRUDA (pembrolizumab) therapy.

In November, the company presented encouraging and consistent results from the Phase 1b/2 trial of SD-101 in combination with KEYTRUDA at the ESMO (Free ESMO Whitepaper) 2018 Congress:

In patients with advanced melanoma who are naïve to anti-PD-1 therapy

70% overall response rate (ORR) in the 2-milligram dose cohort

Tumor shrinkage occurred in both injected target lesions and non-injected target lesions; non-injected lesions demonstrated an ORR of 68%, including visceral metastases in the lung and liver

The ORR is identical to that reported at ASCO (Free ASCO Whitepaper) 2018, despite increasing the patient population by more than 50%, from 30 to 47 patients

85% 6-month progression-free survival (PFS) rate

Observed responses in injected lesions and non-injected distant lesions

Responses were independent of baseline PD-L1 expression

In patients with melanoma refractory or resistant to anti-PD-1 therapy

20.7% ORR in 29 patients in the 8-milligram dose cohort

In patients with head and neck squamous cell carcinoma who were naïve to anti-PD-1 therapy

27.3% ORR in 22 patients in the 8-milligram dose cohort

Dynavax has fully enrolled the 2-milligram cohort in patients with melanoma refractory or resistant to anti-PD-1 therapy and in patients with head and neck squamous cell carcinoma who were naïve to anti-PD-1 therapy. Data from these cohorts are expected later this year.

SD-101 and KEYTRUDA are being evaluated in a new randomized, controlled, investigational treatment arm for the ongoing I-SPY 2 TRIAL for neoadjuvant treatment of locally advanced breast cancer.

Adverse events related to SD-101 treatment have been transient, mild to moderate flu-like symptoms.

DV281

DV281 is a TLR9 agonist designed for delivery to lung cancer patients by inhalation.

Dynavax is conducting a Phase 1b/2 clinical trial in subjects with advanced non-small cell lung cancer to investigate the safety and tolerability of DV281 as monotherapy and in combination with OPDIVO (nivolumab) and to identify a recommended dose for the expansion part of the study.

Studies in preclinical animal models of metastatic cancer show that direct delivery of DV281 to tumor-bearing lungs results in induction of interferons and cytokines and infiltration of T cells, responses similar to those observed after intratumoral injection of SD-101.

Dynavax will present a poster (Abstract 8304) from the safety portion of the inhaled DV281 study at the AACR (Free AACR Whitepaper) Annual Meeting. The poster titled "Phase Ib/II, open label, multicenter study of inhaled DV281, a Toll-like receptor 9 agonist, in combination with nivolumab in patients with advanced or metastatic non small cell lung cancer (NSCLC)" will be presented Tuesday, April 2, 2019, from 1 to 5 p.m. ET.

Preclinical Research

Dynavax has multiple immuno-oncology preclinical research programs including a cancer vaccine program and a multi-pronged program to develop TLR7 and TLR8 agonists, both as anti-cancer agents and as vaccine adjuvants. The company is also evaluating additional candidates to leverage the hepatitis B 1018 adjuvant in additional vaccines.

Financial Results

Product Revenue, Net. Dynavax’s first commercial product, HEPLISAV-B, was launched in the first quarter of 2018. Net product revenue for the fourth quarter of 2018 was $3.9 million, compared to $1.5 million in the third quarter of 2018. Net product revenue for the full year 2018 was $6.8 million. Product revenue from sales is recorded at the net sales price, which includes estimates of product returns, chargebacks, discounts and other fees.

Cost of Sales, Product. Cost of sales, product, for the fourth quarter of 2018 was $1.6 million and $10.9 million for the year ended December 31, 2018. Included in cost of sales, product, are inventory reserves and fill, finish and overhead costs for HEPLISAV-B incurred after FDA approval. Also included are costs associated with resuming operations at the manufacturing facility in Düsseldorf after receiving regulatory approval for the pre-filled syringe presentation, which costs previously were included in research and development expense.

R&D Expenses. Research and development expenses for the fourth quarter of 2018 totaled $22.9 million compared to $17.4 for the fourth quarter 2017. Full year 2018 research and development expenses totaled $75.0 million compared to $65.0 million in 2017. The increase

reflects increased compensation and related personnel costs and clinical trial and research expenses related to the ongoing development of SD-101, DV281 and earlier stage oncology programs. Upon approval of pre-filled syringes in the first quarter 2018, costs associated with resuming activities at the manufacturing facility in Düsseldorf were charged to cost of sales, product while costs incurred to manufacture HEPLISAV-B for commercial sale were accounted for as inventory.

SG&A. Selling, general and administrative expenses for the fourth quarter of 2018 totaled $16.4 million compared to $9.3 million for the fourth quarter of 2017. Full year 2018 selling, general and administrative expenses totaled $64.8 million compared to $27.4 million in 2017. The increase in full year 2018 is primarily due to an overall increase in HEPLISAV-B sales, marketing and commercial activities, including full-deployment of a contract sales force, post-marketing studies and consultants for commercial development services.

Net Loss. Net loss for the fourth quarter of 2018 was $40.0 million, or $0.64 per basic and diluted share, compared to a net loss of $27.4 million, or $0.45 per basic and diluted share, for the fourth quarter of 2017. Full year 2018 net loss was $158.9 million, or $2.55 per basic and diluted share, compared to a net loss of $95.2 million, or $1.81 per basic and diluted share for the full year 2017.

Cash Position. Cash, cash equivalents and marketable securities totaled $145.5 million at December 31, 2018, compared to $191.9 million at December 31, 2017. Dynavax plans to borrow $75.0 million under its non-dilutive term loan agreement in the first quarter of 2019 to support commercial efforts and advance its immuno-oncology platform.

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. In 2015, new cases of acute hepatitis B increased by more than 20 percent nationally.ii 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 CDC recommends vaccination for those at high risk for infection due to their jobs, lifestyle, living situations and travel to certain areas.iii 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.iv Approximately 20 million U.S. adults have diabetes, and 1.5 million new cases of diabetes are diagnosed each year.v

About HEPLISAV-B
