EMERYVILLE, Calif.,?March 26, 2020?(GLOBE NEWSWIRE) --?Dynavax Technologies Corporation?(Nasdaq: DVAX), a biopharmaceutical company focused on developing and commercializing novel vaccines, and the?Coalition for Epidemic Preparedness Innovations?(CEPI) today announced a collaboration supporting the global effort to develop a vaccine to prevent the coronavirus (COVID-19).?Dynavax?will make the Company?s proprietary toll-like receptor 9 (TLR9) agonist adjuvant, CpG 1018^TM, available for the development of effective vaccines against COVID-19.

CpG 1018 is the adjuvant used in HEPLISAV-B^??[Hepatitis B Vaccine (Recombinant), Adjuvanted], an adult hepatitis B vaccine approved by the?U.S. Food and Drug Administration?(FDA).?Dynavax?developed CpG 1018 to provide an increased vaccine immune response, which has been demonstrated in HEPLISAV-B. CpG 1018 provides a well-developed technology and a significant safety database, potentially accelerating the development and large-scale manufacturing of a COVID-19 vaccine.

?Dynavax?s mission is to develop and commercialize innovative vaccines to prevent disease and support patients,? commented?Ryan Spencer, Chief Executive Officer of?Dynavax. ?We are proud to support CEPI?s efforts to address this global public health emergency with our advanced adjuvant technology.?

As?previously announced, the CEPI initiative to develop a vaccine to prevent COVID-19 led to the collaboration between?Dynavax?and the?University of Queensland,?Australia. ?CEPI and?Dynavax?will work together to identify and coordinate engagements with entities around the world working on COVID-19 vaccines. The focus of this collaboration is to identify programs that could benefit from combination with CPG 1018 to provide a more rapid or robust immune response.

CEPI?s work on COVID-19

The rapid global spread and unique epidemiological characteristics of the novel coronavirus are deeply concerning. CEPI has moved with great urgency and in coordination with WHO, who is leading the development of a coordinated international response. So far, CEPI has initiated 8 partnerships to improve understanding and to develop vaccines against the novel coronavirus. The programmes will leverage rapid response platforms already supported by CEPI as well as new partnerships. The aim is to advance COVID-19 vaccine candidates into clinical testing as quickly as possible.? Follow CEPI?s?COVID-19 page?for the latest updates.
