  Purpose

This is a 12 month randomized, open-label, parallel-group study to obtain data on the frequency and variability of exacerbations in severe and very severe Chronic Obstructive Pulmonary Disease (COPD) patients (Global Initiative for Chronic Obstructive Lung Disease (GOLD) Stage III and IV) receiving salmeterol xinafoate and fluticasone propionate either in fixed combination (SFC) or from separate inhalers (Sal/FP) with standard therapy. 200 subjects will be enrolled in approximately 30 study centres in Germany. Data on health care utilisation will be collected to compare direct costs associated with COPD in these two groups.

Baseline data will be collected for all subjects at Visit 1 and eligible subjects will be randomized to receive either SFC 50/500 µg bid (twice daily) as fixed combination or Sal 50 µg bid (twice daily) and FP 500 µg bid (twice daily) concurrently over 52 weeks. Subjects will return for study visits every two to three months until week 52. Additional telephone calls will be made between scheduled visits every 4 weeks. Assessments will include monitoring of frequency of exacerbations, health care utilisation (including emergency visits and hospitalizations) and rescue medication, lung function, drug compliance, health-related quality of life (SGRQ = St George's Respiratory Questionnaire) and safety.

Primary Outcome Measures:
  • Mean Number of Exacerbations Per Year: Negative Binomial Model [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    During regular visits, participants were asked whether they experienced any exacerbation since last contact. Between visits, COPD participants were contacted by phone by the staff and asked about exacerbation details. Exacerbations were defined according to Rodriguez-Roisin: moderate (grade II) exacerbations include a worsening of COPD symptoms that require both a change of respiratory medication (increased dose of prescribed or addition of new drugs) and medical assistance; severe (grade III) exacerbations include deterioration in COPD resulting in hospitalization or emergency room treatment.

  • Mean Number of Exacerbations Per Year: Poisson Model [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    During regular visits, participants were asked whether they experienced any exacerbation since last contact. Between visits, COPD participants were contacted by phone by the staff and asked about exacerbation details. Exacerbations were defined according to Rodriguez-Roisin: moderate (grade II) exacerbations include a worsening of COPD symptoms that require both a change of respiratory medication (increased dose of prescribed or addition of new drugs) and medical assistance; severe (grade III) exacerbations include deterioration in COPD resulting in hospitalization or emergency room treatment.


Secondary Outcome Measures:
  • Compliance and Adherence to Study Medication [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    Compliance is calculated as the ratio (in percent) between the number of actual doses taken during the total treatment period divided by the number of doses that should have been taken during the total treatment period.

  • Mean Number of COPD-related Visits at/by Physician [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    The total number of COPD-related visits, i.e., from baseline through week 52, the number of visits at physician's office, the number of home visits made by physician, the number of visits at an emergency outpatient clinic, as well as the number of home visits by an emergency physician were summed up.

  • Number of Participants With the Indicated Number of Days at the Intensive Care Unit (ICU) [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    The number participants with the indicated number of days at the ICU was recorded.

  • Number of Participants With the Indicated Number of Hospital Stays [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    The number of participants with the indicated number of hospitalizations was recorded.

  • Mean Number of Days Rescue Medication Was Used [ Time Frame: The 7 days before baseline (=Visit 2 [Week 8]) and the last 7 days of study (=Visit 6 [Week 52]) ] [ Designated as safety issue: No ]
    Participants were asked for the number of days they used rescue medication within the 7 days before Week 8 and Week 52.

  • Mean Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    Change from baseline was calculated as the FEV1 percent predicted value at Week 52 minus the percent predicted value at baseline. The post-bronchodilator lung function test was performed to measure FEV1 30 minutes after inhaling salbutamol. The most reliable result of three different consecutive measurements was documented.

  • Mean Change From Baseline in Inspiratory Vital Capacity (IVC) at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    Change from baseline was measured as the IVC value at Week 52 minus the value at baseline. The post-bronchodilator lung function test was performed to measure IVC 30 minutes after inhaling salbutamol. The most reliable result of three different, consecutive measurements was documented.

  • Mean Change From Baseline in the Tiffeaneau Index at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    The Tiffeneau index is defined as the FEV1 divided by the IVC (i.e., forced expiratory volume in one second relative to the inspiratory capacity) in percent. Change from baseline is calculated as the FEV1/IVC value at Week 52 minus the value at baseline.

  • Mean Change From Baseline in the Symptom Score of the St. George's Respiratory Questionnaire (SGRQ) at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    Change from baseline is calculated as the symptom score at Week 52 minus the symptom score at baseline. The SGRQ (a self-administered questionnaire) subscale symptom score ranges from 0 to 100% and measures the effect of respiratory symptoms, frequency, and severity on quality of life (summed weights of 8 questions). A score of 0 indicates the best possible status.

  • Mean Change From Baseline in the Activity Score of the St. George's Respiratory Questionnaire (SGRQ) at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    Change from baseline is calculated as the activity score at Week 52 minus the score at baseline. The SGRQ (a self-administered questionnaire) subscale activity score ranges from 0 to 100% and is concerned with activities that cause or are limited by breathlessness (summed weights of 2 questions). A score of 0 indicates the best possible status.

  • Mean Change From Baseline in the Impact Score of the St. George's Respiratory Questionnaire (SGRQ) at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    Change from baseline was calculated as the impact score at Week 52 minus the score at baseline. The SGRQ (a self-administered questionnaire) subscale impact score ranges from 0 to 100% and is concerned with social functioning and psychological disturbances (summed weights of 5 questions). A score of 0 indicates the best possible status.

  • Mean Change From Baseline in the Total Score of the St. George's Respiratory Questionnaire (SGRQ) at Week 52 [ Time Frame: Baseline and Week 52 ] [ Designated as safety issue: No ]
    Change from baseline was calculated as the total score at Week 52 minus the score at baseline. The SGRQ (a self-administered questionnaire) total score ranges from 0 to 100% and summarizes the impact of COPD on overall health status (summed weights of 15 questions). A total score of 0 indicates the best possible status.

  • Mean Total Costs (Related to COPD) Per Participant [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    Total costs include costs for hospitalization, medication, and visits to/by physician. Medications that were used "as required" were assumed to be used every second day.
