A Multi-center Trial Comparing the Efficacy and Safety of GSK573719/GW642444 With GSK573719 and With Tiotropium Over 24 Weeks in Subjects With COPD

This is a Phase III multicenter, randomized, double-blind, double-dummy, parallel-group
study to evaluate the efficacy and safety of two doses of GSK573719/GW642444 Inhalation
Powder, GSK573719 Inhalation Powder via a Novel Dry Powder Inhaler and tiotropium via
HandiHaler when administered once-daily over a 24-week treatment period in subjects with
chronic obstructive pulmonary disease (COPD). Subjects who meet eligibility criteria at
Screening (Visit 1) will complete a 7 to10 day run-in period followed by a randomization
visit (Visit 2) then a 24-week treatment period. There will be a total of 9 clinic study
visits. A follow-up phone contact for adverse event assessment will be conducted
approximately one week after the last study visit (Visit 9 or Early Withdrawal). The total
duration of subject participation in the study will be approximately 26 weeks. The primary
measure of efficacy is clinic visit trough (pre-bronchodilator and pre-dose) forced
expiratory volume in one second (FEV1) on Treatment Day 169. Safety will be assessed by
adverse events, 12-lead ECGs, vital signs, and clinical laboratory tests.

This is a 24-week, Phase III multicenter, randomized, double-blind, double-dummy,
parallel-group study. Eligible subjects will be randomized to GSK573719/GW642444 125/25mcg,
GSK573719/GW642444 62.5/25mcg, GSK573719 125mcg, or tiotropium treatment groups in a 1:1:1:1
ratio. Treatments will be administered once-daily in the morning by inhalation using a Novel
Dry Powder Inhaler (Novel DPI) and HandiHaler. There will be a total of 9 study clinic
visits conducted on an outpatient basis. Subjects who meet the eligibility criteria at
Screening (Visit 1) will complete a 7 to 10 day run-in period followed by a 24-week
treatment period. Clinic visits will be at Screening, Randomization (Day 1), Day 2, after 4,
8, 12, 16, and 24-weeks of treatment, and 1 day after the Week 24 Visit (also referred as
Treatment Day 169). A follow-up contact for adverse assessment will be conducted by
telephone approximately 7 days after Visit 9 or the Early Withdrawal Visit. The total
duration of subject participation, including follow-up will be approximately 26 weeks. All
subjects will be provided with albuterol/salbutamol for use on an "as-needed" basis
throughout the run-in and study treatment periods. At screening, pre-bronchodilator
spirometry testing will be followed by post-albuterol/salbutamol spirometry testing.
Post-albuterol/salbutamol FEV1 and FEV1/forced vital capacity (FVC) values will be used to
determine subject eligibility. To further characterize bronchodilator responsiveness,
post-ipratropium testing will be conducted following completion of post-albuterol/salbutamol
spirometry. Spirometry will be conducted at each post-randomization clinic visit. Six hour
post-dose serial spirometry will be conducted at Visits 2, 6, and 8. Trough spirometry will
be obtained 23 and 24 hours after the previous day's dose of blinded study medication at
Visits 3 to 9. All subjects will be provided with an electronic diary (eDiary) for
completion daily in the morning and the evening throughout the run-in and treatment periods.
Subjects will use the eDiary to record peak expiratory flow (PEF) each morning, dyspnea
scores using the Shortness of Breath with Daily Activities instrument (SOBDA), daily use of
supplemental albuterol/salbutamol as either puffs/day from a metered-dose inhaler (MDI)
and/or nebules used per day, and any healthcare contacts related to COPD. Additional
assessments of dyspnea will be obtained using the Baseline and Transition Dyspnea Index
(BDI/TDI) which is an interviewer based instrument. At Visit 2, the severity of dyspnea at
baseline will be assessed using the BDI. At subsequent visits (Visits 4, 6, and 8) change
from baseline will be assessed using the TDI. General health status will be evaluated using
the subject-completed EQ-5D questionnaire at Visits 2, 4, 6, and 8. Disease specific health
status will be evaluated using the subject-completed St. George's Respiratory Questionnaire
(SGRQ) at Visits 2, 4, 6, and 8, and the subject-completed COPD Assessment Test (CAT) at
Visits 2, 6, and 8. The occurrence of adverse events will be evaluated throughout the study
beginning at Visit 2. SAEs will be collected over the same time period as for AEs. However,
any SAEs assessed as related to study participation (e.g., study treatment,
protocol-mandated procedures, invasive tests, or change in existing therapy) or related to a
GSK concomitant medication, will be recorded from the time a subject consents to participate
in the study up to and including any follow up contact. Additional safety assessments of
vital signs (blood pressure and pulse rate), 12-lead ECGs and standard clinical laboratory
tests (hematology and chemistry) will be obtained at selected clinic visits.
