Change From Baseline in Pre-dose (Trough) Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: Pre-dose at Baseline and Treatment Weeks 8, 10 and 12 ] [ Designated as safety issue: No ]
FEV1 is a measure, in liters, of the amount of air expired in 1 second. Measured values were averaged during the placebo run-in period for baseline and over the last 4 weeks of the 12-week treatment period for on-treatment. For participants who did not have any measurements over the last 4 weeks of the 12-week treatment period, the last available on-treatment measurement was carried forward.

  • Change From Baseline in Overall Daytime Symptoms Score [ Time Frame: Baseline and Treatment Weeks 8, 10 and 12 ] [ Designated as safety issue: No ]
    On a daily diary card, participants rated their responses to the question "Overall, how much of the time did you have symptoms from your lung disease today?" (0=none of the time; 5=all of the time). Scores range from 0 to 5, with higher scores indicating more time with symptoms. The overall daytime symptoms score value was the mean daily diary score during the placebo run-in period for baseline and over the last 4 weeks of the 12-week treatment period for on-treatment.
  • Change From Baseline in Total Daily Beta-agonist Use [ Time Frame: Baseline and Treatment Weeks 8, 10 and 12 ] [ Designated as safety issue: No ]
    The total daily beta-agonist use was measured in puffs per day and was recorded on daily diary cards by participants. It is defined as the sum of beta-agonist use between when participants arose from and went to bed. The total daily beta-agonist use values were the recorded mean during the placebo run-in period for baseline and over the last 4 weeks of the 12-week treatment period for on-treatment.
  • Change From Baseline in Saint George's Respiratory Questionnaire (SGRQ) Response [ Time Frame: Baseline and Treatment Weeks 8 and 12 ] [ Designated as safety issue: No ]
    The SGRQ consists of 76 items in 3 domains: Symptoms (frequency and severity), Activity (activities that cause or are limited by breathlessness) and Impacts (social functioning, psychological disturbances resulting from airways disease). Scores for each domain and a total score are calculated; each questionnaire response has a unique empirically dervied "weight". Scores range from 0 to 100, with higher scores indicating poor health. Each domain of the questionnaire is scored separately in 2 steps: 1) The weights for all items with a positive response are summed; 2) The score is calculated by dividing the summed weights by the maximum possible weight for that domain and expressing the results as a percentage. The mean SGRQ scores were calculated during the placebo run-in period for baseline and over the last 4 weeks of the 12-week treatment period for on-treatment.
  • Transition Dyspnea Index (TDI) Focal Score [ Time Frame: Baseline and Treatment Week 12 ] [ Designated as safety issue: No ]
    The baseline dyspnea index (BDI) was measured at the randomization visit as a 3-domain score with a scale of 0 to 4 in each domain, with a total focal score of 12 indicating no dyspnea limitation and 0 indicating severe dyspnea. After 12 weeks of treatment, the investigator-administered TDI was completed, with a change in each of the 3 domains being rated from -3 (major deterioration) to +3 (major improvement), so that the TDI focal score could range from -9 to +9. A higher TDI focal score indicates improvement.
  • Change From Baseline in Shortness of Breath Questionnaire (SOBQ) Response [ Time Frame: Baseline and Treatment Weeks 8 and 12 ] [ Designated as safety issue: No ]
    The SOBQ is a validated 24-item measure of dyspnea associated with activities of daily living in patients with moderate to severe chronic lung disease. Twenty-one items ask patients about how frequently they experience shortness of breath (SOB) on a 6-point scale of 0 (never) to 5 (activity given up due to dyspnea) when performing various tasks. Three additional questions about limitations due to SOB, fear of harm from overexertion and fear of SOB are included for a total of 24 items. If patients do not routinely perform the activity indicated in the questionnaire, they are asked to estimate the degree of SOB anticipated. The SOBQ total score is calculated by summing responses across all 24 items. The total score ranges from 0 to 120, with a higher score indicating greater frequency of and limitations due to SOB. The score assessed at the baseline visit was used for the baseline score and the mean score assessed at Treatment Weeks 8 and 12 was used as the on-treatment score.
  • Number of Participants With at Least One Chronic Obstructive Pulmonary Disease (COPD) Exacerbation [ Time Frame: Baseline through Treatment Week 12 ] [ Designated as safety issue: No ]
    COPD exacerbation is defined as any change in symptoms or functional status that leads to administration (at investigator's discretion) of systemic corticosteroids (above participant's usual dose) and/or antibiotics, or an unscheduled COPD-related hospitalization, emergency room visit, or doctor visit. The number of participants who experienced at least one COPD exacerbation during the 12-week treatment period is reported.
  • Change From Baseline in Predose (Trough) Forced Vital Capacity (FVC) [ Time Frame: Predose at Baseline and Treatment Weeks 8, 10 and 12 ] [ Designated as safety issue: No ]
    FVC is a measure, in liters and using a spirometer, of the amount of air forcibly exhaled from the lungs after taking the deepest breath possible. The values averaged during the placebo run-in period were used for the baseline measurement and the values averaged over Treatment Weeks 8, 10 and 12 were used for the on-treatment measurement. A higher value indicates greater lung exiratory function.

An Investigational Drug Study In Patients With COPD (Chronic Obstructive Pulmonary Disease) (MK-0873-005)
A Double-Blind, Randomized, Placebo-Controlled, Multicenter, Parallel-Group, Dose-Ranging Study of MK-0873 in Patients With COPD

This is a study to evaluate the effectiveness and tolerability of a once-daily oral medication (MK-0873) for the treatment of COPD (chronic obstructive pulmonary disease) to determine whether the study drug leads to an improvement in pulmonary (lung) function, as well as symptoms, and quality of life.

Following a three-week run-in period (Period I) during which participants received placebo, participants entered into a 12-week double-blind treatment period (Period II) during which they received daily doses of either one of three doses of MK-0873 or placebo. Period I and Period II made up the Base Study. Following the 12-week treatment period in the Base Study, participants were invited to continue in an optional 12-week double-blind extension study (Period III, EXT1). Participants who received any dose of MK-0873 in the Base Study continued on MK-0873 2.5 mg daily in Period III while participants in the placebo arm of the Base Study continued on placebo daily. Following EXT1, participants were invited to continue in an optional open-label second extension study (EXT2) which was to last 80 weeks (Period IV: 28 weeks, Period V: 52 weeks). In EXT2, participants who had been taking MK-0873 2.5 mg in the Base Study were allocated to MK-0873 2.5 mg plus usual care, while participants who had been taking the other two doses of MK-0873 or placebo in the Base Study were allocated to either MK-0873 2.5 mg plus usual care or to usual care alone.
