A Long-Term Safety Trial of Treatment With Nebulized SUN-101 in Patients With COPD

This is a Phase 3, randomized, open-label, active-controlled, parallel-group, multicenter, long-term safety trial of 48 weeks of treatment with nebulized SUN-101 using an Investigational eFlow® Closed System (CS) nebulizer or Spiriva in approximately 1050 subjects with chronic obstructive pulmonary disease (COPD) according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD 2014) guidelines. Eligible subjects will enter the 48-week, open-label treatment period following randomization to receive one of two treatments (SUN-101 given as 50 mcg BID or Spiriva® \[tiotropium\] given as 18 mcg QD). The hypothesis for this study is that the incidence of treatment-emergent adverse events reported over the course of 48 weeks of treatment by subjects randomized to SUN-101 is numerically similar to the incidence of treatment-emergent adverse events reported over the course of 48 weeks of treatment by subject randomized to Spiriva (tiotropium).
