DEREGISTRATION OF UNSOLD SECURITIES

        On August 16, 1999, IDEC Pharmaceuticals Corporation (the "Registrant") filed its Registration Statement on Form S-3 (File No. 333-85339) (the "Registration Statement") covering $345,000,000 principal amount of its Liquid Yield Option™ Notes due 2019 (Zero Coupon—Subordinated) (the "1999 LYONs") and the 13,939,380 shares of the Registrant's common stock, $0.001 par value (the "Common Stock") issuable upon conversion of such 1999 LYONs (as adjusted for the December 1999 two-for-one stock and the January 2001 three-for-one stock split by way of stock dividend) to be sold by certain selling securityholders of the Company. On November 12, 1999, the Securities and Exchange Commission (the "Commission") declared the Registration Statement effective.

        Pursuant to Rule 477 promulgated under Securities Act of 1933 (the "Securities Act") and the Registrant's undertaking in Item 17 of Part II of this Registration Statement, the Registrant respectfully requests that the Commission withdraw the Registrant's Registration Statement, including all amendments and exhibits thereto, with respect to the unsold portion of securities registered hereon. The Registration Statement was filed in order to register the 1999 LYONs issued to purchasers in private placements in February 1999 and the shares of Common Stock into which the 1999 LYONs are convertible. As of October 16, 2002 the selling securityholders have re-sold $337,976,000 principal amount of the 1999 LYONs and up to 13,655,598 shares of Common Stock under the Registration Statement.

        The Registrant is requesting the withdrawal of the Registration Statement because, pursuant to the terms of the Registration Rights Agreement between the Company and the initial purchasers of the 1999 LYONs, the company's obligation to maintain the effectiveness of the Registration Statement under the Registration Rights Agreement expired in February 2001.

        Accordingly, the Registrant hereby de-registers $7,024,000 in principal amount of the LYONs and 283,782 shares of its Common Stock into which the LYONs are convertible that were registered pursuant to the Registration Statement and remain unsold thereunder.

        Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing this Post-Effective Amendment No. 1 to the Registration Statement and has duly caused this Post-Effective Amendment No. 1 to its Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Diego, State of California, on the 17th day of December, 2002.
