Long-term Safety Study for GSK573719 in Japanese

Phase 3

Completed

Conditions: Pulmonary Disease, Chronic Obstructive

Interventions: Drug: GSK573719

Registration Number: NCT01702363

Lead Sponsor: GlaxoSmithKline

Brief Summary: The objective of this study is to evaluate the safety and tolerability of GSK573719 Inhalation Powder 125 mcg once-daily over 52 weeks in Japanese subjects with COPD.

Detailed Description: Chronic Obstructive Pulmonary Disease (COPD) treatment guidelines recommend an incremental approach to pharmacological treatment as the disease state worsens, involving the use of combinations of drug classes with different or complementary mechanisms of action \[Celli, 2004, GOLD 2009\]. As disease progresses from mild to moderate, regular treatment with one or more long-acting bronchodilators is recommended. Inhaled bronchodilators, including beta2 agonists and anticholinergics are included with inhaled corticosteroids (ICS) therapy and are mainstays of therapy in patients diagnosed with COPD. Since GSK573719 Inhalation Powder is expected to be used for chronic management of COPD as long-acting muscarinic antagonist (LAMA), this study is intended to evaluate the safety and tolerability of long-term administration of GSK573719 Inhalation Powder 125 mcg in Japanese patients with COPD at doses possibly used to be in Japan.

In this study, patient safety will also be monitored by evaluating pulmonary function and clinical symptoms.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Any Adverse Event (AE) or Any Serious Adverse Event (SAE) Throughout the Treatment Period	From the first dose of study medication up to 52 weeks	An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of the study medication, whether or not considered related to the study medication. An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the study medication. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability or incapacity, or is a congenital anomaly or birth defect, or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition, or is an event of possible drug-induced liver injury. Medical or scientific judgment was exercised in deciding whether reporting was appropriate in other situations.
Number of Participants With AEs Classified by the Indicated Maximum Grade Severity Throughout the Treatment Period	From the first dose of study medication up to 52 weeks	An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of the study medication, whether or not considered related to the study medication. An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the study medication. AEs were classified according to intensity based upon the investigators' clinical judgment. The intensity was categorized as: mild (an event that is easily tolerated by the participant, causing minimal discomfort and not interfering with everyday activities); moderate (an event that is sufficiently discomforting to interfere with normal everyday activities); or severe (an event that prevents normal everyday activities).

An abnormal and significant ECG finding includes the presence of a QT interval corrected for heart rate (QTc interval) \>500 milliseconds (msec) or an uncorrected QT interval \>600 msec, for participants with Bundle Branch Block QTc \>530 msec based on an average QTc value of triplicate ECGs. The study investigator determined if the abnormal ECG finding was CS or NCS. The WD Visit was conducted for participants who withdrew at any point during the study.
