Exhibit 4.1

Description of the Capital Stock

The following is a description of the common stock, $0.0001 par value per share (“Common Stock”) of Sunesis Pharmaceuticals, Inc. (the “Company”), which is the only security of the Company registered pursuant to Section 12 of the Securities and Exchange Act of 1934, as amended. The following summary describes the material terms of our Common Stock. The description of our Common Stock is based on the provisions of our amended and restated certificate of incorporation, our amended and restated bylaws and the applicable provisions of the Delaware General Corporation Law (the “DGCL”). This information may not be complete in all respects and is qualified entirely by reference to our amended and restated certificate of incorporation, our amended and restated bylaws and the DGCL. For a complete description of the terms and provisions of the Company’s capital stock, including its Common Stock, refer to our amended and restated certificate of incorporation and our amended and restated bylaws, both of which are filed as exhibits to this Annual Report on Form 10-K to which this Description of Capital Stock is an exhibit. Capitalized terms used but not defined herein have the meanings given them our amended and restated certificate of incorporation.

Common Stock

The Company is authorized to issue up to 400,000,000 shares of Common Stock. The holders of Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders and do not have cumulative voting rights with respect to the election of directors. Generally, all matters to be voted on by stockholders must be approved by the holders of a majority of the Common Stock and Preferred Stock (voting together as a single class on an as-if converted basis), or, in the case of the election of directors, a plurality, represented at a meeting at which a quorum is present. Subject to preferences that may be applicable to the outstanding shares of Preferred Stock, the holders of Common Stock are entitled to receive ratably such dividends as may be declared by the board of directors out of funds legally available therefor. Upon the liquidation, dissolution or winding up of the Company, holders of our Common Stock are entitled to share ratably in all assets legally available for distribution to stockholders remaining after payment of liabilities and the liquidation preferences of outstanding shares of Preferred Stock. Holders of Common Stock have no preemptive rights and no right to convert their Common Stock into any other securities. There are no redemption or sinking fund provisions applicable to our Common Stock.

Anti-Takeover Effects of Provisions of Charter Documents and Delaware Law

Charter Documents

In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three classes, with staggered three-year terms. Only one class of directors is elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Because our stockholders do not have cumulative voting rights, in the case of the election of directors, holders of a plurality of the Common Stock represented at a meeting at which a quorum is present will be able to elect all of our directors. Our amended and restated certificate of incorporation and our amended and restated bylaws provide that all actions taken by the holders of Common Stock must be effected at a duly called meeting of stockholders and not by a consent in writing, and that only our board of directors, chairman of the board, chief executive officer, or president (in the absence of a chief executive officer) or holder of greater than 10% of our Common Stock may call a special meeting of stockholders. Our amended and restated certificate of incorporation requires a 66- 2/3% stockholder vote for the amendment, repeal or modification of certain provisions of our amended and restated certificate of incorporation and our amended and restated bylaws relating to the absence of cumulative voting, the classification of our board of directors, the requirement that stockholder actions be effected at a duly called meeting, and the designated parties entitled to call a special meeting of the stockholders.

The classification of our board of directors, the lack of cumulative voting and the 66- 2/3% stockholder voting requirements make it more difficult for our existing holders of our Common Stock to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing holders of our Common Stock or another party to effect a change in management.

In addition, the authorization of undesignated Preferred Stock makes it possible for our board of directors to issue shares of Preferred Stock with voting or other rights or preferences that could impede the success of any attempt to change our control. Our amended and restated certificate of incorporation authorizes our board of directors to issue up to 10,000,000 shares of

our Preferred Stock, of which, as of December 31, 2020: (i) 5,000,000 are designated Series A Preferred Stock, none of which are issued and outstanding as, (ii) 30,000 are designated as Series B Preferred Stock, none of which are issued and outstanding, (iii) 3,000 are designated as Series C Preferred Stock, none of which are issued and outstanding, (iv) 2,500 are designated as Series D Preferred Stock, none of which are issued and outstanding, (v) 17,000 are designated as Series E Preferred Stock, 1,915 of which are issued and outstanding and (vi) 8,333 are designated as Series F Preferred Stock, all of which are issued and outstanding. For a complete description of the terms and provisions of the Company’s Preferred Stock, refer to our amended and restated certificate of incorporation and our amended and restated bylaws, both of which are filed as exhibits to this Annual Report on Form 10-K to which this Description of Capital Stock is an exhibit.

These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened change in control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.

Section 203 of the Delaware General Corporation Law

We are subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in a business combination with any interested stockholder for a period of three years following the date the person became an interested stockholder, with the following exceptions:

| • |  | before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested holder;
| • |  | upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (a) by persons who are directors and also officers and (b) pursuant to employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; and
| • |  | on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 of the DGCL defines business combination to include the following:

| • |  | any merger or consolidation involving the corporation and the interested stockholder;
| • |  | any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;
| • |  | subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
| • |  | any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; and
| • |  | the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.

Section 203 of the DGCL defines an “interested stockholder” as an entity or person who, together with the entity’s or person’s affiliates and associates, beneficially owns, or is an affiliate of the corporation and within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the

corporation. A Delaware corporation may “opt out” of these provisions with an express provision in its certificate of incorporation. We have not opted out of these provisions, which may as a result, discourage or prevent mergers or other takeover or change of control attempts of us.

Forum Selection Bylaw

Our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a breach of fiduciary duty; (iii) any action asserting a claim against us arising under the DGCL; (iv) any action regarding our amended and restated bylaws; (v) any action as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; or (vi) any action asserting a claim against us that is governed by the internal affairs doctrine. Our amended and restated bylaws further provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. We believe this provision benefits us by providing increased consistency in the application of Delaware law by chancellors particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. However, the provision may have the effect of discouraging lawsuits against our directors and officers.
