About

The primary objective of this study is to evaluate the effect of 12 weeks of treatment with once daily administration of AQX-1125 compared to placebo in subjects following exacerbations of Chronic Obstructive Pulmonary Disease (COPD) by targeting the SHIP1 (Src Homology 2-containing Inositol-5'-Phosphatase 1) pathway.

Full description

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity and mortality worldwide. Acute exacerbations of COPD are usually treated with steroids and/or antibiotics. Currently this conventional therapy has significant side effects including osteoporosis, cataracts and suppression of the immune system (from the steroids) and increasing bacterial resistance and other side effects from the use of antibiotics. During an acute exacerbation of COPD, the inflammation in the airways increases.

AQX-1125 represents a new type drug that based current data is thought decrease the inflammatory process and therefore may provide a therapeutic benefit in the treatment of COPD.

5. Presentation of a diagnosed acute exacerbation of COPD, or have recently (within 3 days) been discharged from hospital due to an acute exacerbation of COPD
6. Ability to perform pulmonary function testing and with documented fixed airway obstruction determined by an FEV1 /FVC [forced vital capacity] ratio (post-bronchodilator) of <0.70 and a predicted FEV1 value of 30%-80% of normal within the 6 months prior to Visit 1.
