     This Amendment No. 1 to Schedule 13D is being filed by Amgen Inc., a
Delaware corporation (the "Reporting Person"), to amend the Schedule 13D filed
on December 22, 1998, relating to shares of Common Stock of $0.001 par value
("Common Stock"), of NPS Pharmaceuticals, Inc., a Delaware corporation (the
"Issuer"). The Reporting Person has fallen below the five percent threshold of
ownership of the Issuer's Common Stock for reporting under Section 13(d) of the
Securities Exchange Act of 1934, as amended. Unless otherwise indicated, all
capitalized terms used herein but not defined herein shall have the meaning
assigned to them in the Schedule 13D.

Item 5.  Interest in Securities of the Issuer
- ------

(a)  As of the date of this Schedule 13D, Amgen beneficially owns 1,000,000
     shares of the Issuer's Common Stock (the "Shares") which is approximately
     3.99% of the outstanding shares of the Issuer's Common Stock as identified
     in the Issuer's Quarterly Report on Form 10-Q for the quarter ended
     September 30, 2000.

(b)  Amgen has the sole power to vote or to direct the vote and sole power to
     dispose or to direct the disposition of the Shares.

(c)  There were no other transactions in the Common Stock of the Issuer that
     were effected during the past sixty days by Amgen.

(d)  To the best knowledge of Amgen, no person other than Amgen has the right to
     receive or the power to direct the receipt of dividends from, or the
     proceeds from the sale of the Shares.

(e)  NA

                                       4


                                   SIGNATURE

          After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
