Formoterol Via pMDI HFA-134a Propellant or DPI in Partially Reversible Chronic Obstructive Pulmonary Disease (COPD)
Study Details
Study Description
Brief Summary
The purpose of this study is to demonstrate equivalent efficacy between two different formulations of formoterol (pMDI using HFA-134 propellant and dry powder) on lung function in adult patients with partially reversible COPD.

Phase 2 |
Detailed Description
The present study is aimed at investigating the effect of a single 12 µg dose and of a short 7-day course of formoterol HFA-134a, compared to a formoterol DPI formulation, on specific parameters that are appropriate for assessment of single-dose and short-term effects on COPD.
This study has been designed to assess the efficacy with the traditional use of FEV1. Furthermore, the use of other efficacy parameters such as changes in exertion tolerance and dyspnoea, dynamic and static volumes measured using a whole body plethysmograph, such as TLC, RV, IC and airways conductance sGAW has been included.
This is a double blind, double dummy, multicentre, randomised, placebo-controlled, cross-over study in at least 36 adult patients with partially reversible COPD. The two test treatments and placebo will be administered in a single and repeated (twice daily for 7 days) dose cycle (with a minimum 2 days and maximum 7 days of wash-out between each cycle).
Seven clinic visits in total will take place at the start and end of the run-in period, and at the first and at the last dose of each treatment cycle (with placebo and the two active treatment tests), with an acceptable variation of a maximum of ± 1 day in respect of the scheduled days at the end of each treatment cycle (i.e. treatment with placebo or active drug may range between 6 and 8 days).

Eligibility Criteria
Criteria
Inclusion Criteria:

-
Positive partial response to the reversibility test in the screening visit, defined as an increase from baseline value of at least 5% of the percentage of predicted normal value (post-dosing minus pre-dosing/pre-dosing x 100) in the FEV1 measurement 30 minutes following 4 puffs (4 x 100 µg) of inhaled salbutamol pMDI.
-
Current or past tobacco heavy smoking habits (defined as smoking for > 20 pack years, where 1 pack year = 20 cigarettes/day for 1 year or equivalent).
-
A cooperative attitude and ability to be trained to use correctly the pMDI and the AerolizerTM inhaler.
-
Written informed consent obtained.
Exclusion Criteria:
