Pulmatrix, Inc. announced that it has entered into a further amendment to its agreement with Cipla for the development of PUR1900 in the treatment of Allergic Bronchopulmonary Aspergillosis (ABPA). Under the terms of the amendment Cipla and Pulmatrix agreed, among other things, to stop patient enrollment of the Ph2b study of PUR1900 at 8 subjects and close the study. Pursuant to the amended agreement with Cipla, Pulmatrix has granted Cipla exclusive rights to the development and commercialization of PUR1900 in the "Cipla Territory", which has been expanded to include all markets other than the United States.

In the United States, both parties will seek to monetize PUR1900 which has potential for development in areas other than ABPA in Asthma. After the study winddown, Pulmatrix will bear no further financial responsibility for the development of PUR1900 and will receive 2% royalties on net sales of Pulmazole in the Cipla Territory.
