                                                                    Exhibit 99.1

                  Nektar Announces First Quarter 2005 Results

     SAN CARLOS, Calif.--(BUSINESS WIRE)--May 9, 2005--Nektar Therapeutics
(Nasdaq:NKTR) announced today its financial results for the first quarter ended
March 31, 2005.
     The company reported revenue of $28.5 million for the three months ended
March 31, 2005, compared to $25.8 million for the first quarter of 2004. In the
first quarter of 2005, product revenue was $6.4 million compared to $4.3 million
in 2004, and contract research revenue totaled $19.5 million compared to $21.5
million in 2004. For the first time, the company reported Exubera(R)
commercialization readiness revenue received from Pfizer for reimbursement of
certain agreed upon operating costs related to the Exubera (inhaled insulin)
drug powder manufacturing facility in preparation for commercial production. For
the first quarter 2005, Exubera commercialization readiness revenue was $2.6
million.
     The company reported a net loss of $26.2 million or $(0.31) per share for
the three months ended March 31, 2005, compared to a net loss in the same
quarter in 2004 of $40.0 million or $(0.64) per share. The net loss for the
three month period ended March 31, 2004 includes $12.7 million in payments made
in connection with conversion of convertible subordinated notes, and a loss from
debt extinguishment of $9.3 million.
     As of March 31, 2005, the company reported cash, cash equivalents and
short-term investments totaling approximately $401 million compared to
approximately $419 million as of December 31, 2004.
     "A key milestone was met during the first quarter 2005 with the acceptance
by the U.S. Food and Drug Administration (FDA) of the new drug application (NDA)
for Exubera (inhaled insulin)," said Ajit S. Gill, Nektar president and CEO. "If
Exubera is approved, we believe it will be a breakthrough in the treatment of
diabetes and an important part of Nektar's future."
     On March 2, 2005, Pfizer and Sanofi-Aventis announced that the U.S. FDA had
accepted for filing a new drug application for Exubera and that the review of
the Exubera marketing authorization application in Europe is actively
proceeding. Nektar develops and provides the inhalers and the powdered insulin
for the Exubera product. Pfizer and Sanofi-Aventis seek approval to market
Exubera for adult patients with type 1 and type 2 diabetes.
     In a separate press release, Nektar also announced today the appointment of
Joseph Krivulka to its Board of Directors.
