A Multicenter Trial Comparing the Efficacy and Safety of GSK573719/GW642444 With GW642444 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 and
GW642444 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, GW642444 25mcg, 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.
