             Nektar Announces Third Quarter 2005 Financial Results

     SAN CARLOS, Calif.--(BUSINESS WIRE)--Nov. 3, 2005--Nektar Therapeutics
(Nasdaq:NKTR):

     --   Exubera(R) receives positive recommendations in Europe and US; FDA
          extends review period by 3 months;

     --   Company strengthens balance sheet.

     Nektar Therapeutics (Nasdaq:NKTR) announced today its financial results for
the third quarter ended September 30, 2005.
     The Company reported total revenue of $36.4 million for the three months
ended September 30, 2005 compared to $28.5 million for the three months ended
September 30, 2004. In the third quarter of 2005, product and royalty revenue
was $8.5 million compared to $5.0 million in the third quarter of 2004, and
contract revenue totaled $23.7 million compared to $23.6 million in the third
quarter of 2004. Nektar also reported that in the third quarter of 2005 the
Company received $4.2 million from Pfizer for Exubera(R) (inhaled insulin)
commercialization readiness for reimbursement of certain agreed upon operating
costs related to the Exubera drug powder manufacturing facility in preparation
for commercial production.
     Nektar reported a net loss of $23.8 million or $(0.28) per share for the
three months ended September 30, 2005 compared to a net loss of $20.5 million or
$(0.24) per share for the three months ended September 30, 2004.
     For the nine months ended September 30, 2005, Nektar reported total revenue
of $93.4 million compared to $82.9 million for the nine months ended September
30, 2004. For the nine months ended September 30, 2005, product and royalty
revenue was $20.3 million compared to $15.7 million for the nine months ended
September 30, 2004, and contract research revenue totaled $62.7 million compared
to $67.2 million for the nine months ended September 30, 2004. Exubera
commercialization readiness totaled $10.3 million for the first nine months of
2005.
     For the nine months ended September 30, 2005, Nektar reported a net loss of
$76.9 million or $(0.90) per share compared to a net loss for the nine months
ended September 30, 2004 of $82.6 million or $(1.08) per share.
     As of September 30, 2005, the Company reported cash, cash equivalents and
short-term investments of approximately $620.3 million compared to $378.5
million as of June 30, 2005. The cash, cash equivalents and short-term
investments include the net proceeds from the sale of $315 million aggregate
principal amount of its 3.25% convertible subordinated notes due 2012.

     Substantial Progress Made

     "This quarter Nektar achieved multiple milestones, including the
recommendations for Exubera approval, announcement of two proprietary products,
and new partner activities," said Ajit S. Gill, president and chief executive
officer.

     Exubera Approval Recommended in the EU and US; FDA Extends Review Period 3
Months

     "The recommendations of the approval of Exubera in the US and the EU are
significant milestones. The next steps for Exubera are final approvals from both
regulatory agencies," said Gill.

     --   On September 8, 2005, a US Food and Drug Administration (FDA) advisory
          committee panel recommended the approval of Exubera (insulin (rDNA
          origin) powder for oral inhalation), an inhaleable, rapid-acting
          powder insulin for the treatment of adults with type 1 and type 2
          diabetes. While the FDA usually follows the advice of its advisory
          committees, it is not obligated to do so.

     --   On October 13, 2005, the Committee for Medicinal Products for Human
          Use (CHMP) of the European Medicines Evaluation Agency (EMEA) issued a
          positive opinion recommending approval of Exubera. The European
          Commission is expected to act upon that recommendation early next
          year.

     --   On October 28, 2005, the FDA notified Pfizer and sanofi-aventis that
          it is extending its original review period for Exubera by three
          months.

     Nektar pioneered the advanced pulmonary technology for Exubera, including
the inhaler, the formulation for the powdered insulin, and the manufacturing
processes for making and packaging the powdered insulin.

     Nektar Proprietary Products Target Local Lung Infections in Seriously Ill
Patients; Aerogen Acquisition Broadens Pulmonary Leadership

     "Nektar announced two proprietary products that highlight how our
technology and expertise can generate unique product opportunities for Nektar
that will enable us to build a high-value pipeline. These new products could
help reduce mortality rates from fungal and bacterial lung infections while
reducing the costs of patient treatment. Because they focus on improving
existing medicines, they offer a lower risk profile with potential excellent
returns-on-investment compared with typical new drug development programs," said
Gill.
     On September 29, 2005 at its Investor Day in New York, Nektar disclosed two
anti-infective products targeted at preventing local lung infections in
seriously ill patients.

     --   Inhaled amphotericin B product is being developed for preventing fatal
          pulmonary fungal infections in immunosuppressed patients to reduce the
          incidence, morbidity, mortality and high cost of treating these
          infections. Using a small proprietary pocket size inhaler, the company
          has conducted two Phase I trials and has long-term toxicity studies
          underway to support the planned pivotal trials. More than 150,000
          patients annually in the US and Europe are at risk of developing often
          fatal and costly fungal infections in the lungs. Nektar's inhaleable
          amphotericin B potentially could be the first prophylactic therapy to
          prevent these serious infections.

     --   Inhaled ICU antibiotics product is being developed for the prevention
          of ventilator-associated pneumonia (VAP) in the intensive care unit
          (ICU). VAP is a form of hospital-acquired, or nosocomial pneumonia,
          occurring in patients on mechanical ventilators. Nektar's novel
          drug-device system uses a nebulizer and Nektar proprietary adapter
          technology, along with a unique formulation of liquid antibiotics, to
          target the lungs directly with preventative doses of medicine in a
          ventilated patient. More than 450,000 patients in the US are at the
          highest risk for this disease. A proof-of-principle study sponsored by
          Nektar demonstrated that aerosolized antibiotics reduce the
          persistence of VAP after its onset by approximately half as compared
          to placebo.

     The acquisition of Aerogen, Inc., which closed on October 20, 2005, will
broaden Nektar's pulmonary technology base by adding capabilities in aerosolized
liquid drugs to Nektar's leadership position with inhaleable powdered drugs.
Initially, Nektar will incorporate Aerogen technology into its proprietary
inhaled ICU antibiotics product.

     Partner Pipeline Progress: New Collaboration with Baxter; Advances in the
Clinic

     "We also saw progress in our partner pipeline. The new collaboration with
Baxter exemplifies the higher value Nektar can gain through investment in early
product concept work," said Gill. "The initiation of Phase III trials of
tobramycin inhalation powder (TIP) by Chiron is an indication that our unique
powder formulation and advanced inhaleable technologies may enable innovative
therapeutics, such as TIP, to target local lung infections."

     --   On September 29, 2005, Nektar announced an agreement with subsidiaries
          of Baxter International Inc. to develop PEGylated therapeutic forms of
          blood clotting proteins for patients with hemophilia, in order to
          reduce the frequency of injections required to treat blood clotting
          disorders such as hemophilia A. This agreement allows Nektar to
          capitalize on the internal work on PEGylated proteins to provide
          Baxter with a differentiated product.

     --   On October 5, 2005, Chiron Corporation and Nektar announced the
          initiation of clinical testing in the Phase III program evaluating
          tobramycin inhalation powder (TIP), an investigational inhaled
          antibiotic. The TIP Phase III program includes two clinical trials and
          will evaluate the efficacy and safety of TIP in the treatment of lung
          infections caused by Pseudomonas aeruginosa in patients living with
          cystic fibrosis (CF). The first trial, called ASPIRE I, is underway.
