Assess Particle Deposition and Acute Effects of Symbicort® Forte Turbohaler®) in COPD Patients.

April 1, 2011 updated by: University Hospital, Antwerp

A Randomized, Double-blind, Placebo-controlled, Two Way Cross-over Study to Assess the Particle Deposition and Acute Effects of Formoterol and Budesonide Combination Therapy (Symbicort® Forte Turbohaler®) on the Upper Airway Dimensions in COPD Patients.

Computational Fluid Dynamics (CFD) is a new functional imaging method. Since CFD is very sensitive to detect small changes, it might be worthwhile to study the acute effect of formoterol and budesonide combination therapy (Symbicort® forte Turbohaler®) on the upper airway dimensions in severe COPD patients (GOLD III). The increased sensitivity of this technique makes it possible to detect changes in airway caliber in early stages. The regional distribution of resistance and the change in this parameter will provide more insight into the mode of action of the product.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Patients with documented COPD based on the following criteria:

    Smoking history of at least 10 pack-years and decreased Tiffeneau index (FEV1/(F)VC < 0.70).

  2. Patients should present severe COPD with an FEV1 between 50 and 30% of predicted (GOLD 3).
  3. Male or female patients aged ≥ 40 years.
  4. Patients should be treated according to GOLD guidelines before study start.
  5. Patients with, in the opinion of the investigator, a co-operative attitude and ability to be trained to correctly use the TurbohalerR.
  6. Maintained on stable respiratory medications for 6 weeks prior to visit 1.
  7. Written informed consent obtained.

Exclusion Criteria:

  1. Pregnancy, breast-feeding or planned pregnancy during the study. Fertile women not using acceptable contraceptive measures, as judged by the investigator.
  2. Inability to carry out pulmonary function testing.
  3. A respiratory infection or exacerbation of COPD in the four weeks prior to screening.
  4. Any significant disease or disorder which, in the opinion of the investigator, may either put the patient at risk because of participation in the study, or influence the results of the study, or the patient's ability to participate in the study
  5. A history of asthma, cystic fibrosis, central bronchiectasis, interstitial lung disease or pulmonary thromboembolic disease.
  6. Cancer or any other chronic disease with poor prognosis and/or affecting patient status.
  7. A history of thoracotomy with pulmonary resection.
  8. Allergy, sensitivity or intolerance to study drugs and/or study drug formulation ingredients.
  9. History of alcohol or drug abuse.
  10. Patients unlikely to comply with the protocol or unable to understand the nature, scope and possible consequences of the study.
  11. Patients who received any investigational new drug within the last 4 weeks prior to the screening visit.
  12. Patients treated with any non-permitted concomitant medication (see 7.2).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
total airway resistance
To evaluate the effect of the combination therapy on the upper airway dimensions and to assess the particle deposition with Computational Fluid Dynamics (CFD). The parameters that will be obtained with CFD and used as primary outcome variables are total airway resistance and total airway volume.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
effect of formoterol and budesonide combination therapy on lung function
The secondary objective of this study is to assess the effect of formoterol and budesonide combination therapy on lung function (spirometry, body plethysmography and resistance).
