DISKUS vs. ELLIPTA Device Preference Study in Chronic Obstructive Pulmonary Disease (COPD)

RLV116669, A Preference Study of Device Attributes Between Two Placebo Dry Powder Inhalers; ELLIPTA and DISKUS, in Adult Subjects With Chronic Obstructive Pulmonary Disease

Subjects who have not used the ELLIPTA™ inhaler nor the DISKUS™ inhaler in the past 6 months will be screened to participate in the study. Subjects will have an equal chance of being in any of the following two groups (1:1 allocation). One group will be dispensed the ELLIPTA inhaler at Visit 1 to use during the first period (once daily for 5 to9 days), and the DISKUS inhaler at Visit 2 to use during the second period (twice daily for 5 to 9 days). The other group will be dispensed the DISKUS inhaler at Visit 1 to use during the first period (twice daily for 5 to 9 days), and the ELLIPTA inhaler at Visit 2 to use during the second period (once daily for 5 to9 days). At the end of the second period, subjects will complete the study by answering 7 questions to assess their preference of device attributes and dosing regimens between the two inhalers.

The null hypothesis for device preference for a specific attribute is that 50% subjects express a preference in that attribute for ELLIPTA and 50% do NOT express a preference in that attribute for ELLIPTA, i.e., the odds for preferring ELLIPTA to not preferring ELLIPTA is unity.

The null hypothesis for dosing regimen preference is that 50% subjects express a preference of once daily dosing and 50% do not express a preference of once daily dosing (prefer twice daily dosing or have no preference).

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 40 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• 1. Informed consent
• Subject must give their signed and dated written informed consent to participate.
• Subject understands and is willing, able, and likely to comply with study procedures and restrictions.
• Subject must be able to read, comprehend, and record information in English.
• 2. Age: >=40 years of age at Visit 1
• 3. Gender: Male or female subjects
• 4. COPD diagnosis subjects with a clinical history of COPD in accordance with the definition by the American Thoracic Society/European Respiratory Society
• 5. Severity of disease:
• Subject with a measured post-albuterol Forced expiratory volume in 1 second (FEV1)/ Forced vital capacity (FVC) ratio of <=0.70 at Visit 1
• Subjects with a measured post-albuterol FEV1 <=70% of predicted normal values calculated using Third National Health and Nutrition Examination Survey reference equations at Visit 1.
• Post-bronchodilator spirometry will be performed approximately 10-15 minutes after the subject has self-administered 4 inhalations (i.e., total 400 micrograms) of albuterol via a metered dose inhaler (MDI) with a valved-holding chamber. The FEV1/FVC ratio and FEV1 percent predicted values will be calculated by the investigator site.
• Documented spirometry measurements that meet this criterion in the last 12 months preceding Visit 1 is acceptable.
• 6. Tobacco use: current or former smokers
• Smokers are defined as those who smoke 10 pack-years of cigarette.
• Note: Pipe and/or cigar use cannot be used to calculate pack-year history.
• Number of pack years = (number of cigarettes per day/20) x number of years smoked

Exclusion Criteria:

• 1. Previous experience with the DISKUS inhaler
• Subjects who used any DISKUS inhaler (e.g., ADVAIR DISKUS, FLOVENT DISKUS®; participated in a clinical study of fluticasone propionate/salmeterol, or any component of them, or placebo) within 6 months (i.e., 180 days) prior to Visit 1.
• 2. Previous experience with the ELLIPTA inhaler
• Subjects who used any ELLIPTA inhaler (e.g., participated in a clinical study of FF/VI or GSK573719/GW642444 [umeclidinium/vilanterol], or any component of them, or placebo) within 6 months (i.e., 180 days) prior to Visit 1.

• Use of a total of 8 puffs/day or more of short-acting symptom relief medications such as albuterol and ipratropium for 2 consecutive days or any 3 days within 7 days immediately preceding Visit 1.
• Changes in COPD symptoms and signs, suggesting worsening COPD health status at Visit 1.
• 5. Other diseases/abnormalities: Subjects with current evidence of uncontrolled or clinically significant disease.
• Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study.

• Note: subjects who develop oropharyngeal candidiasis during the study will be treated at the discretion of the investigator.
• 6. Drug/food allergy: Subjects with a history of hypersensitivity to any of the components of the inhalation powder (e.g., lactose, magnesium stearate).
