EXHIBIT INDEX Exhibit No. Description 99.1 Earnings Press Release of Nektar Therapeutics dated April 22, 2003.

                                                                Exhibit 99.1

           Netkar Announces First Quarter 2003 Results

    SAN CARLOS, Calif.--(BUSINESS WIRE)--April 22, 2003--Nektar
Therapeutics (Nasdaq:NKTR), formerly Inhale Therapeutic Systems, Inc.,
announced today its financial results (under generally accepted
accounting principles) for the first quarter ending March 31, 2003.
The Company reported revenue of $25.5 million for the three months
ending March 31, 2003, including $7.1 million of product revenue and
$18.4 million of contract research revenue compared to $26.7 in the
same period in 2002, including $5.4 million of product revenue and
$21.3 million of contract research revenue. The decrease in revenue
reported during the first three months of 2003 compared to the first
three months of 2002 is due primarily to lower clinical drug and
device sales for our partnered projects.
    The Company reported a net loss of $19.9 million or $(0.36) per
share for the three months ending March 31, 2003 compared to $25.1
million or $(0.45) per share for the same period in 2002.
    The Company's cash balance at the end of the quarter was $251.5
million versus $294.0 million at the end of 2002. The net cash usage
for the three months ending March 31, 2003 was $42.5 million. The
March 31, 2003 cash balance does not reflect a $12.3 million receipt,
which was collected on April 1, 2003. First quarter cash usage did
include $2.6 million of disbursements associated with the Company's
reduction-in-force announced in the fourth quarter 2002 and $1.3
million of disbursements related to the Company's name change.
    "During the first quarter, we advanced partner and proprietary
product programs, as well as made progress on scale-up and regulatory
filing preparation for Exubera(R)," said Ajit S. Gill, president and
chief executive officer (CEO). "We continue to target an increase in
revenues in 2003 and a decrease in our operating loss compared to
2002."

    Summary of First Quarter Activities

    Partner Pipeline

    "We are pleased with the continued progress in our partnered
product pipeline during the quarter. A major highlight for us was
gaining regulatory approval of the fifth product in the United States
using our technology, Pfizer's (formerly Pharmacia's) SOMAVERT(R),"
said Gill. On March 27, 2003, Nektar reported that SOMAVERT, which
uses Nektar's PEGylation technology, was approved by the Food and Drug
Administration (FDA) for the treatment of certain patients with
acromegaly, a debilitating disease caused by a noncancerous tumor on
the pituitary gland that produces increased quantities of growth
hormone.
    An additional product using Nektar technology entered the clinic
early in the quarter. InterMune, Inc. on January 23 announced that it
initiated a Phase I clinical study to evaluate PEG-Alfacon, the
PEGylated version of Infergen(R) (interferon alfacon-1), as a
potential new treatment for chronic hepatitis C virus.
    Nektar also announced a collaboration with The Straumann Group, a
leader in implant dentistry, to license, manufacture and supply
Nektar's PEG-based hydrogel technology for dental regeneration
products.

    Exubera

    "Pfizer and Aventis are continuing long-term safety testing for
the Exubera inhaled insulin product, and in January Pfizer indicated
that it does not expect to file for approval in 2003," continued Gill.
"We made additional progress in the quarter on scale-up of
manufacturing for the product and are continuing our work to prepare
for the regulatory filing of Exubera." Nektar provides advanced drug
formulation and inhaler technology and manufacturing to Pfizer to
develop Exubera, an inhaled, rapid-acting, powdered insulin for
diabetes. Pfizer has entered into an agreement with Aventis to
co-develop, co-promote and co-manufacture Exubera.

    Proprietary Pipeline

    "As part of our continuing effort to become the leading drug
delivery company, we plan to transition from being a drug delivery
technology provider to a company that also leverages its drug delivery
platforms to develop enhanced products through Phase I/II clinical
trials before partnering for further development," said Gill. "Charged
with fulfilling this mission, the recently-formed Proprietary Products
Group made advances on several fronts. Most notably, we started Phase
I clinical trials on an inhaled small-molecule, supergeneric drug
product with the first patient dosing in March 2003. We believe that
our proprietary products program will become a strong third business
base and revenue generation source together with our partnership
pipeline and Exubera," continued Gill.

    Management Changes to Support Growth Strategy

    In February 2003, Nektar announced the creation of a new executive
position to drive development and implementation of management and
operations processes to achieve Nektar's growth and profitability
objectives. Brigid Makes, previously Nektar's chief financial officer
(CFO), was named to this new senior management position, vice
president of operations management. Ajay Bansal, formerly of Mehta
Partners, Novartis, and McKinsey, has joined Nektar as its new CFO.
    Nektar Therapeutics, formerly Inhale Therapeutic Systems, Inc.,
provides industry-leading drug delivery technologies, expertise and
manufacturing to enable the development of high-value, differentiated
therapeutics. Nektar's advanced drug delivery capabilities are
designed to enable Nektar's biotechnology and pharmaceutical partners
to solve drug development challenges and realize the full potential of
their therapeutics, from developing new molecular entities to managing
the lifecycles of established products. For additional information,

    This release contains forward-looking statements that reflect the
current views of Nektar management as to future operating results,
products, product development, and other future events and operations.
These forward-looking statements involve uncertainties and other risks
that are detailed in the Company's reports and other filings with the
Securities and Exchange Commission, including its most recent Annual
Report on Form 10-K. These documents identify important factors that
could cause the Company's actual performance to differ from current
expectations, including, without limitation, the outcome of clinical
trials, the status of its relationship with collaborative partners,
regulatory review, manufacturing capabilities, marketing
effectiveness, and the ability of the Company to manage its cash and
other assets in light of its ongoing operating costs and outstanding
indebtedness.
