Registration Statement on Form S-3

File No. 333-121724

Ladies and Gentlemen:

In accordance with Rule 461 of the General Rules and Regulations under the Securities Act of 1933,
a request is hereby made on behalf of Human Genome Sciences, Inc. (the “Company”) that acceleration
of the effective date of the above-captioned Registration Statement be granted by the Commission in
order that the Registration Statement shall become effective at 12:00
p.m. on Monday, February
14, 2005, or as soon thereafter as practicable.

In this regard, the Registrants acknowledge that:

    •
    should the Securities and Exchange Commission (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 this action as a defense in any proceeding initiated by the Commission or
any person under the federal securities laws of the United States.

    Sincerely,

    HUMAN GENOME SCIENCES, INC.

By:

    /s/ James H. Davis
