Immuno-oncology

  -- Overall response rate (ORR) of 70%
  -- 80% ORR  in patients with low PD-L1

“The launch is progressing as planned and I continue to expect HEPLISAV-B will become the standard of care for vaccination of adults against hepatitis B. During my field visits, I have personally witnessed the strength of the product profile and label in motivating customers to switch vaccines,” said Eddie Gray, chief executive officer of Dynavax. “Our efforts to date are beginning to pay off with increasing sales, which we expect will accelerate during Q4 and into 2019, when we expect HEPLISAV-B to be cash generative before year end.  In addition, we continue to advance our SD-101 clinical program which has shown encouraging results so far in both melanoma and head and neck carcinoma patients. We look forward to updating these data later this year.”

Financial Results
Cash, cash equivalents and marketable securities of $216.0 million at end of the second quarter, with $75 million available from the February 2018 term loan agreement

Net product revenue was $1.3 million for the quarter ended June 30, 2018, which consists of sales of HEPLISAV-B in the U.S. 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 was $5.2 million for the quarter ended June 30, 2018 and consists of certain fill, finish and fixed overhead costs for HEPLISAV-B incurred after FDA approval and costs relating to excess capacity at our Dusseldorf manufacturing facility associated with resuming operations after receiving FDA approval of HEPLISAV-B and pre-filled syringes.

Cost of sales, amortization of intangible assets was $2.3 million for the quarter ended June 30, 2018 and consists of amortization of the intangible asset recorded as a result of milestone and sublicense payments relating to HEPLISAV-B.

Research and development expenses for the quarter ended June 30, 2018 and 2017, were $16.3 million and $14.8 million, respectively. The increase in 2018 reflects increased compensation and related personnel costs related to the ongoing development of SD-101, DV281 and earlier stage oncology programs. Additionally, in the current quarter, manufacturing related costs incurred by our Dusseldorf facility that were previously included in research and development expense are now accounted for as excess capacity in our cost of sales, product.

Selling, general and administrative expenses for the quarter ended June 30, 2018 and 2017, were $15.7 million and $5.6 million, respectively. The increase 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.

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
