The Effect of STIOLTO™ RESPIMAT® on Fatigue in Chronic Obstructive Pulmonary Disease

• Status: Completed
• Trial end date: 2018-08-06
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine whether exercise can be prolonged in COPD can by the inhaled bronchodilator Stiolto Respimat. The study will identify whether any endurance benefit is due to reduction in fatigue that originates within the skeletal muscles and/or from effects on neural activation of the skeletal muscles.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Los Angeles Biomedical Research Institute; Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center
• Collaborator: Boehringer Ingelheim
• Treatments: Bromides; Olodaterol; Tiotropium Bromide

Criteria

Inclusion Criteria:

• All patients must have a diagnosis of chronic obstructive pulmonary disease and must meet the following criteria: (a) Patients must be in a stable state of their disease with no exacerbation within the previous 4 weeks; and (b) At visit 1 spirometric must demonstrate a post-bronchodilator FEV1 <80% of predicted normal and a post-bronchodilator FEV1/FVC <70%.

• At visit 1, patients will demonstrate appreciable reversibility, defined as a 12% increase in FEV1 in response to albuterol administration.

• Baseline dyspnea index focal score ≤ 9.

• Male or female patients, between 45 and 90 years (inclusive) of age.

• Patients must be current or ex-smokers with a smoking history of more than 10 pack-years

• Patients must be able to perform technically acceptable pulmonary function tests must be able to complete multiple symptom-limited cycle ergometry tests.

• Patients must be able to inhale medication in a competent manner from the inhalers used in the study.

Exclusion Criteria:

• Patients with a significant disease other than COPD; a significant disease is defined as a disease which, in the opinion of the investigator, may (i) put the patient at risk because of participation in the study, (ii) influence the results of the study, or (iii) cause concern regarding the patient's ability to participate in the study.

• Patients with a documented history of asthma. For patients with allergic rhinitis or atopy, medical records will be required to verify that the patient does not have asthma.

• Patients with any of the following conditions:

1. A history of myocardial infarction within 1 year of screening visit.

2. Unstable or life-threatening cardiac arrhythmia.

3. Hospitalized for heart failure within the past year.

4. Known active tuberculosis.

5. A malignancy for which patient has undergone resection, radiation therapy or chemotherapy within last two years (patients with treated basal cell carcinoma are allowed).

6. A history of life-threatening pulmonary obstruction within the past two years.

7. A history of cystic fibrosis.

8. Clinically evident bronchiectasis.

9. A history of significant alcohol or drug abuse within the past two years.

10. Any contraindications for exercise testing as outlined below (see contraindications to exercise).

11. Patients who have undergone thoracotomy with pulmonary resection.

• Patients being treated with 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.

• Patients who regularly use daytime oxygen therapy for more than one hour per day and in the investigator's opinion will be unable to abstain from the use of oxygen therapy during clinic visits.

• Patients who desaturate to SpO2 <85% on screening incremental exercise testing.

• Patients who have completed a pulmonary rehabilitation program in the six weeks prior to the screening visit or patients who are currently in a pulmonary rehabilitation program.

• Patients who have a limitation of exercise performance as a result of factors other than fatigue or exertional dyspnea, such as arthritis in the leg, angina pectoris or claudication or morbid obesity.

• Patients with a constant power cycle ergometry endurance time less than 4 or greater than 10 minutes after work rate adjustment procedures (described below).

• Patients who have taken an investigational drug within one month or six half-lives (whichever is greater) prior to screening visit (Visit 1).

• Pregnant or nursing women.

• Women of childbearing who have the potential not to be using a highly effective method of birth control. Female patients will be considered to be of childbearing potential unless surgically sterilized by hysterectomy or bilateral tubal ligation, or post-menopausal for at least two years.

• Patients who are currently participating in another interventional study.

• Patients who are unable to comply with pulmonary medication restrictions prior to randomization.
