OVERVIEW
Overview
     Dynavax Technologies Corporation (the “Company”) discovers, develops and intends to commercialize innovative products to treat and prevent allergies, infectious diseases, cancer and chronic inflammatory diseases using versatile, proprietary approaches that alter immune system responses in highly specific ways. Our clinical development programs are based on immunostimulatory sequences, or ISS, which are short DNA sequences designed to enhance the ability of the immune system to fight disease and control chronic inflammation. Our most advanced ISS-based clinical pipeline programs are a ragweed allergy immunotherapeutic and a hepatitis B vaccine.
     Our clinical development pipeline currently includes: TOLAMBA™, a ragweed allergy immunotherapeutic, for which a major safety and efficacy trial is currently underway, and that is in a supportive clinical trial in ragweed allergic children; HEPLISAV™, a hepatitis B vaccine that is currently in a Phase 3 clinical trial; SUPERVAX™, a hepatitis B vaccine; and a cancer therapy currently in a Phase 2 clinical trial and anticipated to enter clinical trials in solid tumors. We have preclinical programs in hepatitis B therapy and hepatitis C therapy that are funded by Symphony Dynamo, Inc. (SDI) and preclinical programs focused on chronic inflammation, antiviral therapies and improved, next-generation vaccines using ISS and other technologies. We also have a research collaboration and license agreement with AstraZeneca for the discovery and development of TLR-9 agonist based therapies for the treatment of asthma and chronic pulmonary disease, or COPD. The collaboration will utilize our proprietary second-generation TLR-9 agonist immunostimulatory sequences.
Recent Developments
     TOLAMBA
     TOLAMBA (formerly, Amb a 1 ISS Conjugate or AIC) is a novel injectable product candidate to treat ragweed allergy. In early 2006, we announced results from a two-year Phase 2/3 clinical trial of TOLAMBA showing that patients treated with a single six-week course of TOLAMBA prior to the 2004 season experienced a statistically significant reduction in total nasal symptom scores and other efficacy endpoints compared to placebo-treated patients in the second year of the trial. The safety profile of TOLAMBA was favorable. Systemic side effects were indistinguishable from placebo and local injection site tenderness was minor and transient.
     Following a discussion with the U.S. Food & Drug Administration (FDA) in the first quarter 2006, we decided to conduct an additional major safety and efficacy trial with the goal of determining whether a more intensive, single-course dosing regimen can elicit a greater treatment effect than prior regimens. In the second quarter of 2006, we initiated the Dynavax Allergic Rhinitis TOLAMBA Trial, or DARTT, and announced that enrollment in the DARTT exceeded expectations relative to the speed and number of study subjects. DARTT is a two-year, multi-center, well-controlled study in 738 ragweed allergic subjects, aged 18 to 55 years, randomized into three arms: prior dosing regimen, higher total dose regimen, and placebo. Subjects receive six injections over six weeks prior to the start of the 2006 ragweed season. Ragweed symptoms will be followed over the 2006 and 2007 ragweed seasons. The primary endpoint is reduction in total nasal symptom scores (TNSS) in the higher total dose arm compared to placebo during the second (2007) ragweed season. The trial design includes an interim analysis anticipated to be conducted in early 2007 following completion of the 2006 ragweed season. We anticipate that data from the DARTT interim analysis, if positive, combined with the safety and efficacy data from the recently completed two year Phase 2/3 trial, and from an ongoing trial in ragweed allergic children, could provide sufficient patient data for determining the potential timeline to registration.
     HEPLISAV
     HEPLISAV, our product candidate for hepatitis B prophylaxis, completed a Phase 2/3 trial conducted in Singapore in adults (40 years of age and older) who are more difficult to immunize with conventional vaccines. Results from the final analysis of this trial showed statistically significant superiority in protective antibody response and robustness of protective effect after three vaccinations when compared to GlaxoSmithKline’s Engerix-B®. We intend to focus our development activities and resources on maximizing the potential of HEPLISAV’s demonstrated superiority over conventional hepatitis B vaccine in both the younger (under 40 years of age) and older adult populations, and its potential in the worldwide dialysis market.
     The pivotal Phase 3 trial in the older, more difficult to immunize population in Asia and the U.S.-based Phase 1 trial in patients with end-stage renal disease (pre-hemodialysis) are ongoing. We are in the process of planning additional trials designed to support registration activities. In the second half of 2006, we plan to initiate pivotal Phase 3 safety and efficacy trials for HEPLISAV in the younger adult population in the U.S., Europe and Canada. Also in the second half of 2006, we anticipate initiating a Phase 2 trial in the dialysis population that would be conducted in Europe and/or Canada.

     SUPERVAX
     In April 2006, we announced the acquisition of Rhein Biotech GmbH, which we refer to as Dynavax Europe. As a result, we acquired a hepatitis B vaccine product called SUPERVAX that has been tested in more than 600 subjects and has demonstrated safety and 99% seroprotection compared to conventional vaccine when administered on a convenient, 0, 1-month two-dose schedule. We intend to continue development of and registration activities for SUPERVAX as a two-dose vaccine for commercialization in developing countries.
     Symphony Dynamo, Inc.
     In April 2006, we entered into a series of related agreements with Symphony Capital Partners, LP to advance specific Dynavax ISS-based programs for cancer, hepatitis B therapy and hepatitis C therapy through certain stages of clinical development. Pursuant to the agreements, Symphony Dynamo, Inc. (SDI) has agreed to invest $50.0 million to fund the clinical development of these programs and we have licensed to SDI our intellectual property rights related to these programs. SDI is a wholly-owned subsidiary of Symphony Dynamo Holdings LLC (Holdings), which provided $20.0 million in funding to SDI at closing, and which is obligated to fund an additional $30.0 million in one year following closing. We continue to be primarily responsible for the development of these programs.
     Pursuant to the agreements, we issued to Holdings a five-year warrant to purchase 2,000,000 shares of Dynavax common stock at $7.32 per share, representing a 25% premium over the recent 60-day trading range average of $5.86 per share. The warrant exercise price is subject to reduction to $5.86 per share under certain circumstances. The warrant may be exercised or surrendered for a cash payment upon consummation of an all cash merger or acquisition of Dynavax, the obligation for which would be settled by the surviving entity. In consideration for the warrant, Dynavax received an exclusive purchase option (Purchase Option) to acquire all of the programs through the purchase of all of the equity in Symphony Dynamo during the five-year term at specified prices. The Purchase Option exercise price is payable in cash or a combination of cash and shares of Dynavax common stock, at Dynavax’s sole discretion. Dynavax also has an option to purchase either the hepatitis B or hepatitis C program (Program Option) during the first year of the agreement. The Program Option is exercisable at our sole discretion at a price which is payable in cash only and will be fully creditable against the exercise price for any subsequent exercise of the Purchase Option. If the Company does not exercise its exclusive right to purchase some or all of the programs licensed under the agreement, the intellectual property rights to the programs at the end of the development period will remain with SDI.
     In cancer, we believe that the potent and multifaceted biological activities of ISS offer a number of distinct approaches to cancer therapy in a wide range of tumor types. We are evaluating the potential of ISS to enhance the effect of monoclonal antibodies in cancer therapies. We have conducted an open-label Phase I, dose-escalation trial of ISS in combination with Rituxan® (rituximab) in 20 patients with non-Hodgkin’s lymphoma (NHL). Results of this study showed dose-dependent pharmacological activity without significant toxicity. A follow-up Phase 2 trial of ISS with Rituxan in NHL is currently underway in 30 patients with histologically confirmed CD20+, B-cell follicular NHL who have received at least one previous treatment regimen for lymphoma. The primary objective is to assess the proportion of patients who are alive and without disease progression one year after initiating Rituxan therapy. Mechanistic studies will be performed to characterize the enhancement of antitumor activity by ISS.
     We anticipate that our cancer product candidate will advance into clinical trials in solid tumors in 2006, and our hepatitis B and hepatitis C therapeutic product candidates are currently planned to enter the clinic in 2007.

We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof.
     We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the common stock from us at the public offering price set forth in the prospectus supplement. These purchases will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these purchases.
     To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.
     The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business.

Item 15. Indemnification of Directors and Officers
     Under Section 145 of the General Corporation Law of Delaware (the “Delaware Law”), we have broad powers to indemnify our directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act.
     Our certificate of incorporation and bylaws include provisions to (i) eliminate the personal liability of our directors for monetary damages resulting from breaches of their fiduciary duty to the extent permitted by Delaware Law and (ii) require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware Law, including circumstances in which indemnification is otherwise discretionary. Pursuant to Section 145 of the Delaware Law, a corporation generally has the power to indemnify its present and former directors, officers, employees and agents against expenses incurred by them in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in or not opposed to, the best interests of the corporation and, with respect to any criminal action, had no reasonable cause to believe their conduct was unlawful. We believe that these provisions are necessary to attract and retain qualified persons as directors and executive officers. These provisions do not eliminate the directors’ duty of care, and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware Law. In addition, each director will continue to be subject to liability for breach of the director’s duty of loyalty to us, for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for acts or omissions that the director believes to be contrary to our best interests or the best interests of our stockholders, for any transaction from which the director derived an improper personal benefit, for acts or omissions involving a reckless disregard for the director’s duty to us or our stockholders when the director was aware or should have been aware of a risk of serious injury to us or its stockholders, for acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director’s duty to us or our stockholders, for improper transactions between the director and us and for improper distributions to stockholders and loans to directors and officers. The provision also does not affect a director’s responsibilities under any other law, such as the federal securities law or state or federal environmental laws.
     We have entered into indemnity agreements with our directors and certain of our executive officers that require us to indemnify such persons against expenses, judgments, fines, settlements and other amounts incurred (including expenses of a derivative action) in connection with any proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was one of our directors or executive officers, provided, among other things, that such person’s conduct was not knowingly fraudulent or deliberately dishonest or constituted willful misconduct. The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder.
     At present, there is no pending litigation or proceeding involving any of our directors or executive officers as to which indemnification is being sought nor are we aware of any threatened litigation that may result in claims for indemnification by any executive officer or director.
     We maintain an insurance policy covering our officers and directors with respect to certain liabilities, including liabilities arising under the Securities Act or otherwise.

Item 17. Undertakings
     The undersigned registrant hereby undertakes:
          (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
               (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
               (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
               (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided however that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
          (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
          (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
     The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
     The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.
     Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
