Pfizer Inc and Nektar Therapeutics announced that the two companies have resolved all outstanding contractual issues in connection with Exubera and Nektar's innovative Next Generation Inhaled Insulin (NGI) product currently in phase 1 clinical development.

Under the terms of the agreement, Nektar will receive a one-time payment of $135 million from Pfizer in satisfaction of all remaining obligations under existing agreements relating to Exubera and NGI. In addition, in the event that a new partner is selected, Pfizer has agreed to transfer its remaining rights and all economic benefits for Exubera and NGI. This transfer of Pfizer's interests would include the transfer of the Exubera New Drug Application and Investigational New Drug Applications and all ex-US regulatory filings and applications, continuation of ongoing Exubera clinical trials and certain supply chain transition activities.

"This agreement demonstrates the industry leadership of Pfizer and the company's desire to work with world-class biotechnology partners like Nektar. The agreement strengthens our relationship and demonstrates our ability to work together to craft a solution that allows Nektar the ability to pursue additional commercial opportunities for the Exubera and NGI inhaled insulin franchises.
