Title: Asthma Clinical Research Network (ACRN) Trial - Tiotropium Bromide as an Alternative to Increased Inhaled Corticosteroid in Patients Inadequately Controlled on a Lower Dose of Inhaled Corticosteroid (TALC)
Brief Summary: Typically, people with asthma are initially prescribed a low dose of inhaled corticosteroid (ICS) medication to control asthma symptoms. If a low dose of ICS is ineffective at controlling symptoms, the addition of a second controller medication is recommended. This study will examine the effectiveness of the medication tiotropium bromide combined with a low dose of ICS at maintaining asthma control in people with moderately severe asthma.
