                                                                    Exhibit 99.1



         Nektar Announces Second Quarter 2003 Results


    SAN CARLOS, Calif.--(BUSINESS WIRE)--Aug. 6, 2003--Nektar
Therapeutics (Nasdaq:NKTR), formerly Inhale Therapeutic Systems, Inc.,
announced today its financial results for the second quarter ended
June 30, 2003.
    The Company reported revenue of $27.7 million for the three months
ending June 30, 2003, including $6.5 million of product revenue and
$21.2 million of contract research revenue compared to $22.3 million
for the three months ended June 30, 2002, including $3.4 million of
product revenue and $18.8 million of contract research revenue. The
increase in revenue is due primarily to expanded activities under
existing collaborative agreements and higher sales of Nektar molecule
engineering advanced PEGylation products.
    The Company reported a net loss of $13.0 million or $(0.23) per
share for the three months ending June 30, 2003, compared to a net
loss in the same quarter in 2002 of $24.8 million or $(0.45) per
share.
    For the six months ending June 30, 2003, Nektar reported revenue
of $53.3 million, including $13.7 million of product revenue and $39.6
million of contract research revenue compared to $49.0 million for the
same period in 2002, including $8.9 million of product revenue and
$40.1 million of contract research revenue.
    For the six months ended June 30, 2003, Nektar reported a net loss
of $33.0 million or $(0.59) per share compared to a net loss in the
same period in 2002 of $49.9 million or $(0.90) per share.
    Nektar's balance of cash, cash equivalents and short-term
investments at the end of the quarter was $308.3 million, including
$96.4 million raised in an offering of 3% convertible subordinated
notes due June 2010, net of issuance costs, during the quarter.
Approximately $16.2 million of the proceeds from the sale of 3%
convertible subordinated notes due 2010 were used to retire $20.5
million of 3.5% convertible notes due 2007 in privately negotiated
transactions. This resulted in a $4.3 million gain, which was
reflected as other income in the three and six months ended June 30,
2003. An additional $8.8 million of the proceeds were used to purchase
restricted investments pledged for the benefit of the holders of the
3% convertible subordinated notes purchased in the offering.
    "In addition to improving our cash position through an offering of
subordinated convertible notes, we were also particularly pleased with
the steady advancement in the clinic of three partnered drug products
using our technologies, the release of additional encouraging
Exubera(R) (inhaled insulin) data, and new pre-clinical data from one
of our internally initiated products, PEGylated inhaled insulin," said
Ajit S. Gill, Nektar president and chief executive officer.

    Summary of Activities

    Partner Pipeline Progress

    "Our pipeline continues to grow. There are now 21 products using
Nektar technology approved or in human clinical testing," said Gill.

    --  Nektar announced today that in the second quarter 2003, Unimed
        Pharmaceuticals, Inc., a wholly owned subsidiary of Solvay
        Pharmaceuticals, Inc., initiated a Phase I trial of a metered
        dose inhaler (MDI) version of dronabinol (synthetic
        delta-9-tetrahydrocannabinol). This product is being developed
        for use in multiple indications. Dronabinol is the active
        ingredient in Unimed Pharmaceuticals' product MARINOL(R)
        capsules, which are approved and marketed in the US. This is
        Nektar's first MDI development program.

    --  Chiron Corporation announced on July 23, 2003 that they
        initiated a Phase I trial for inhaled tobramycin, the first
        application of Nektar inhaleable technology to inhaled
        antibiotics for treatment of lung infections. Inhaled Tobi(R)
        is a next-generation inhaled, powder tobramycin product for
        the treatment of Pseudomonas aeruginosa in cystic fibrosis
        patients. Prior to collaborating with Chiron, Nektar had
        previously conducted a proof-of-concept Phase I trial in
        healthy subjects of inhaled powdered tobramycin.

    --  Celltech Group Plc announced progress with one of its products
        that uses Nektar PEGylation technology and services. CDP 860,
        a PEGylated antibody fragment drug in testing for cancer,
        completed a small Phase II proof-of-concept study. According
        to Celltech, the effects observed in this study were
        consistent with the proposed mechanism of action and confirmed
        the potent biological activity of this molecule.

    Exubera(R) (inhaled insulin) Progress

    "Our collaborator, Pfizer, commented in June 2003 at its Analyst
Day that the lung function data from long-term safety tests continues
to look positive and expressed confidence that Exubera(R) (inhaled
insulin) will become an important and widely used diabetes
medication," continued Gill.
    In addition, Nektar reported on new data released in June 2003 at
the American Diabetes Association (ADA) annual conference from Phase
III studies conducted by Pfizer and Aventis with Exubera(R). The data
suggest that Exubera(R) may provide acceptable glycemic control to
significantly more subjects than rosiglitazone in type 2 diabetes
patients not optimally controlled on diet and exercise. Rosiglitazone
is an oral hypoglycemic agent used to reduce the body's resistance to
the action of insulin as a way of lowering blood glucose.

    Proprietary Pipeline Progress

    "In the first half of 2003, we also reported progress in our
proprietary pipeline. As announced in April, an inhaled small molecule
entered clinical testing in the first quarter. In the second quarter,
we released pre-clinical data of PEGylated inhaled insulin,
demonstrating that PEGylated proteins can be formulated into dry
powders to provide prolonged activity," continued Gill.
    In June, Nektar presented pre-clinical data at the ADA from
PEGylated inhaled insulin developed to cross the lungs efficiently and
provide prolonged serum levels of insulin activity.
