Free Combinations of Tiotropium Inhalation Powder Capsule + Salmeterol Metered Dose Inhaler, Tiotropium Inhalation Powder Capsule and Salmeterol Metered Dose Inhaler in Patients With Chronic Obstructive Pulmonary Disease (COPD)

16 de septiembre de 2014 actualizado por: Boehringer Ingelheim

A Randomised, Double-blind, Double-dummy, Crossover Efficacy and Safety Comparison of 6-week Treatment Periods of the Free Combinations of Tiotropium Inhalation Powder Capsule (18 μg) QD + Salmeterol Metered Dose Inhaler (2 Puffs of 25 μg) QD or BID, Tiotropium Inhalation Powder Capsule (18 μg) QD and Salmeterol Metered Dose Inhaler (2 Puffs of 25 μg) BID in Patients With (COPD)

Main Study: To evaluate and to compare the lung function response to the free combinations of tiotropium 18 μg (QD) + salmeterol 50 μg (QD or BID), salmeterol 50 μg BID and tiotropium 18 μg QD at the end of 6-week treatment periods in patients with COPD.

Sub-Study: Was performed in subset of patients participating in the Main Study to assess the effect of the four randomised treatments on dynamic hyperinflation.

Extension Study: To establish whether the FEV1 time profile following combination bronchodilator therapy of tiotropium plus salmeterol is affected by the pharmaceutical formulation of salmeterol, i.e. the MDI or the Diskus®.

Descripción

Inclusion Criteria:

  1. All patients must sign an informed consent consistent with International Conference on Harmonization Good Clinical Practice (ICH-GCP) guidelines prior to participation in the trial, which includes medication washout and restrictions
  2. All patients must have a diagnosis of chronic obstructive pulmonary disease and must meet the following spirometric criteria:

    Patients must have relatively stable, moderate to severe airway obstruction with an FEV1 ≤ 60% of predicted normal and FEV1 ≤ 70% of FVC (Visits 1 and 2)

  3. Male or female patients 40 years of age or older
  4. Patients must be current or ex-smokers with a smoking history of more than 10 pack-years (Patients who had never smoked cigarettes have to be excluded)
  5. Patients must be able to perform technically acceptable pulmonary function tests and must be able to maintain records (Patient Daily Diary Card) during the study period as required in the protocol
  6. Patients must be able to inhale medication in a competent manner from the HandiHaler® device and from a metered dose inhaler (MDI)

Exclusion Criteria:

  1. Patients with significant diseases other than COPD will be excluded. A significant disease is defined as a disease which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study
  2. Patients with clinically relevant abnormal baseline haematology, blood chemistry, or urinalysis, if the abnormality defines a significant disease as defined in exclusion criterion No. 1
  3. Patients with a recent history (i.e. six months or less) of myocardial infarction
  4. Patients with any unstable or life-threatening cardiac arrhythmia or patients who have been hospitalised for such an event within the past year
  5. Patients with a malignancy for which the patient has undergone resection, Radiation therapy or chemotherapy within the last five years. Patients with treated basal cell carcinoma are allowed
  6. Patients with known narrow-angle glaucoma
  7. Patients with a history of asthma, allergic rhinitis or who have a total blood eosinophil count ≥600 mm3
  8. Patients with a history of life-threatening pulmonary obstruction, or a history of cystic fibrosis or clinically evident bronchiectasis
  9. Patients with known active tuberculosis
  10. Patients with a history of and/or active significant alcohol or drug abuse. See exclusion criterion No. 1
  11. Patients who have undergone thoracotomy with pulmonary resection. Patients with a history of thoracotomy for other reasons should be evaluated as per exclusion criterion No. 1
  12. Patients who have completed a pulmonary rehabilitation program in the six weeks prior to the Screening Visit (Visit 1)
  13. Patients who regularly use daytime oxygen therapy
  14. Patients who have taken an investigational drug within one month or six half lives (whichever is greater) prior to Screening Visit (Visit 1)
  15. Patients who are being treated with oral beta-adrenergics
  16. Patients who are being treated with cromolyn sodium or nedocromil sodium
  17. Patients who are being treated with antihistamines (H1 receptor antagonists), antileukotrienes or leukotriene receptor antagonists for asthma or excluded allergic conditions. See exclusion criterion No. 7
  18. Patients using oral corticosteroid medication at unstable doses (i.e., less than six weeks on a stable dose) or at doses in excess of the equivalent of 10 mg of prednisone per day or 20 mg every other day
  19. Patients with known hypersensitivity to anticholinergic drugs, beta-adrenergics, lactose or any other components of the medication delivery systems
  20. Pregnant or nursing women or women of childbearing potential not using a medically approved means of contraception for the previous 3 months (i.e. oral contraceptives, intrauterine devices, diaphragm or subdermal implants eg: Norplant®)
  21. Patients with previous participation (receipt of randomised treatment) in this study
  22. Patients who are currently participating in another study
  23. The randomisation of patients with any respiratory infection or COPD exacerbation in the six weeks prior to the Screening Visit (Visit 1) or during the baseline period should be postponed. Patients may be randomised six weeks following recovery from the infection or exacerbation
