Dear Mr. Riedler:
Pursuant to Rule 461 of Regulation C of the General Rules and Regulations under the Securities Act of 1933, as amended, the undersigned, on behalf of Ligand Pharmaceuticals Incorporated (the “Company”), respectfully requests that the effective date of the Registration Statement on Form S-4 referred to above be accelerated so that it will become effective at 4:00 p.m. Eastern Standard Time on Thursday, November 20, 2008 or as soon as practicable thereafter.
The undersigned, on behalf of the Company, acknowledges the following:
· should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;
· the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and
· the Company may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.
