Item 8.01.    Other Events

Dynavax Technologies Corporation (“Dynavax”) has been informed by its collaborator, AstraZeneca, that initial high-level results from a Phase 2a study indicate AZD1419 treatment was not associated with a statistically significant improvement in the time to loss of asthma control and therefore did not meet the primary endpoint of the study. The treatment appeared to be safe and well tolerated and the study confirmed activation of the TLR9 pathway. AZD1419 is an investigational TLR9 agonist developed by Dynavax in collaboration with AstraZeneca. The proposed mechanism of action of AZD1419 is distinct from that of the other TLR9 agonists being developed by Dynavax for immuno-oncology and vaccine applications.  AstraZeneca will now review the full data before deciding on the next steps for the AZD1419 program. The data will be presented at a future medical meeting.





Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
