SPECTRUM PHARMACEUTICALS, INC.
COMMON STOCK
This prospectus supplement no. 4 relates to the offer and sale of up to 1,550,134 shares of our common stock by the selling stockholders named in the prospectus dated August 21, 2006, as supplemented by prospectus supplement no. 1 dated October 22, 2007, no. 2 dated March 31, 2008 and no. 3 dated April 20, 2009 (the “Prospectus”). This prospectus supplement no. 4 should be read in conjunction with the Prospectus.
In connection with our 2006 acquisition of all the oncology drug assets of Targent, LLC, as the successor to Targent, Inc. (“Targent”), Targent is eligible to receive contingent consideration, in the form of either cash or shares, upon the satisfaction of certain milestones. As a result of the satisfaction of one such milestone in 2011, we are issuing an aggregate of 733,715 shares of our common stock, as directed by Targent, to the individuals named in the Selling Stockholders table below. Pursuant to this prospectus supplement no. 4, as required by the registration rights agreement with Targent, we are registering for resale 244,572 of those 733,715 shares. Other than the asset purchase agreement relating to the acquisition and transactions contemplated thereby, there are no material relationships between the Company and Targent or its stockholders.
The information appearing in the table below, as of the date hereof, supplements the information in the table appearing under the heading “Selling Stockholders” in the Prospectus. This table only provides beneficial ownership information with respect to selling stockholders who are receiving shares of our common stock in connection with the achievement of a milestone related to the acquisition of certain assets from Targent, as described above.
We prepared this table based on the information supplied to us by the selling stockholders named in the table and we have not sought to verify such information. Since the date on which the selling stockholder provided this information, the selling stockholder may have sold, transferred or otherwise disposed of all or a portion of the shares of common stock that he, she or it beneficially owns in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended, or pursuant to an existing resale registration statement.
