AstraZeneca today announced that on 27 June 2013 it completed its acquisition of Pearl Therapeutics, a privately held company based in Redwood City, California, focused on the development of inhaled small-molecule therapeutics for respiratory disease. Upon completion of the merger, AstraZeneca acquired 100% of Pearl's shares.
As previously announced, the acquisition gives AstraZeneca access to a potential new treatment for chronic obstructive pulmonary disease (COPD), currently in late-stage development, and inhaler and formulation technology that provides a platform for future combination products.

About Pearl Therapeutics
Pearl Therapeutics is a company developing inhaled combination therapies for the treatment of highly prevalent respiratory diseases, including chronic obstructive pulmonary disease and asthma. Pearl is rapidly advancing a pipeline of products including PT003, an inhaled, fixed-dose combination bronchodilator product comprised of a long-acting muscarinic antagonist (LAMA) and a long-acting beta-2 agonist (LABA) delivered via a metered dose inhaler (HFA MDI); and PT010, a triple-combination product that combines the LAMA and LABA components of PT003 with an inhaled corticosteroid (ICS) for twice-daily administration from an HFA MDI for the treatment of severe COPD. Both PT003 and PT010 are developed with Pearl's proprietary porous particle co-suspension technology, which allows the formulation of multiple products in the MDI format, with highly stable, robust and aerodynamically efficient drug delivery. Founded in 2006, Pearl Therapeutics was backed by 5AM Ventures, Clarus Ventures, New Leaf Ventures and Vatera Healthcare Partners. For more information, please visit:
