<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;font-weight:bold;;font-size:11pt;">&nbsp;</p>
<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:11pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">BERKELEY, CA, October 8, 2015 &#8211; Dynavax Technologies Corporation (NASDAQ: DVAX) today announced that it has initiated patient dosing in the company&#8217;s trial evaluating the combination of two immunotherapies: Dynavax&#8217;s SD-101 and Merck&#8217;s (NYSE: MRK) KEYTRUDA<sup style="font-size:85%; vertical-align:top">&#174;</sup> (pembrolizumab). The multicenter, open-label trial is enrolling patients with advanced or metastatic melanoma and will investigate the safety and potential efficacy of Dynavax&#8217;s investigational toll-like receptor 9 (TLR9) agonist, SD-101, in combination with Merck&#8217;s anti-PD-1 therapy, KEYTRUDA.&nbsp;&nbsp; </p>
<p style="margin-bottom:0pt;margin-top:0pt;text-indent:7.46%;font-family:Times New Roman;">&nbsp;</p>
<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Arial;font-size:11pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">SD-101 and KEYTRUDA are immunotherapies designed to modulate the patient&#8217;s own immune response to fight cancer. SD-101 is designed to mediate anti-tumor effects by triggering both innate and adaptive immune responses, including inducing high levels of Type 1 interferon. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 (programmed death receptor-1) and its ligands, PD-L1 and PD-L2. Preclinical data suggest that combining SD-101 and antibodies targeting PD-1 may lead to a stronger anti-tumor immune response compared to either agent alone.</p>
<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;">&nbsp;</p>
<p style="margin-bottom:3pt;margin-top:0pt;text-indent:0%;font-size:11pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Phase 1b dose-escalation portion of the study is enrolling up to 12 patients with advanced or metastatic melanoma. Patients will receive intratumoral administrations of SD-101 at pre-specified dose levels and intravenous doses of KEYTRUDA. Patients will be monitored for safety and tolerability while an optimal dose of SD-101 is determined. Upon completion of dose escalation, the study will be expanded into a Phase 2 study that will enroll up to 85 patients. The patients enrolled in the expansion study will either have disease that is progressing while receiving an anti-PD-1 therapy or will have baseline characteristics associated with lower rates of response to anti-PD-1 therapy.</p>

SD-101 activates multiple anti-tumor activities of innate immune cells and activates plasmacytoid dendritic cells to stimulate T cells specific for antigens released from dying tumor cells. TLR9 agonists such as SD-101 enhance T and B cell responses and provide potent Type 1 interferon induction and maturation of plasmacytoid dendritic cells to antigen-presenting cells. SD-101 is being evaluated in several Phase 1/2 oncology studies to assess its preliminary safety and activity. </p>
