Nektar Therapeutics Issues Statement on Exubera

SAN CARLOS, Calif., Oct 18, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- Nektar Therapeutics (Nasdaq: NKTR) issued a statement today in response to Pfizer's announcement this morning to exit Exubera, the inhaled insulin product to treat diabetes.

"We first learned this morning of Pfizer's decision to walk away from Exubera from their press release," said Howard W. Robin, President and Chief Executive Officer of Nektar Therapeutics. "Nektar has been very disappointed in Pfizer's performance in marketing Exubera. Pfizer has publicly acknowledged its organizational difficulties and resulting poor performance in launching Exubera. This has culminated in their announcement today. We are evaluating all of our options with respect to Pfizer's Exubera announcement to protect the interests of Nektar. We continue to believe Exubera is an important advancement for diabetic patients."

Nektar's business has multiple sources of revenue, important partnerships for products on the market and in development, and a diverse pipeline of innovative new proprietary therapies.

The company continues to develop NKTR-102 (PEG-irinotecan) for the treatment of solid tumors, NKTR-118 (PEG-naloxol) to treat opioid bowel dysfunction, and a number of other innovative PEGylation-based product candidates. In addition, progress is being made in the co-development of NKTR-061 (inhaled amikacin) to treat Gram-negative pneumonias with Bayer Schering Pharma AG. Nektar also has a number of other inhaled anti-infective programs in development.
