A Single-center Study to Assess Peak Inspiratory Flow (PIF) in Different Stages' COPD Patients by Using the In-check Method.
An observational study of Pulmonary Disease, run by Elpen Pharmaceutical Co. Inc. at 1 site in Greece.
Trial summary
Peak Inspiratory Flow Rate (PIFR) is defined by the fastest flow rate noted during the inspiratory cycle. Inhaled medication plays an important role in the treatment of chronic obstructive pulmonary disease (COPD), with dry powder inhalers (DPIs) increasingly replacing metered dose inhalers (MDIs).

About this study
Peak Inspiratory Flow Rate (PIFR) is defined by the fastest flow rate noted during the inspiratory cycle.
Inhaled medication plays an important role in the treatment of chronic obstructive pulmonary disease (COPD), with dry powder inhalers (DPIs) increasingly replacing metered dose inhalers (MDIs). DPIs are interesting as they do not require the need for coordinate actuation of the MDI device with inhalation or the use of a large spacer device 1-3. Several DPIs are available for the administration of inhaled corticosteroids, as well as bronchodilators, with each of them corresponding to a different type of inhaler (e.g. Diskus®, Turbuhaler®, Aeroliser®, etc.). During the inspiratory effort the patient generates a pressure drop with a consequent airflow across the DPI. This inspiratory flow has to be high enough to disaggregate and adequately disperse the drug powder into an aerosol cloud of drug particles and to guarantee an optimal deposition of the medication in the lung. Such peak inspiratory flows (PIFs) are not only dependent on a patient's inhalation effort but also on the internal resistance of the device.
It has been shown that optimal deposition of medication with DPIs is not achieved in some patients with low inspiratory flow rates, such as children or patients with COPD, especially during acute exacerbations. In such conditions the use of a DPI with low internal resistance has been suggested, ensuring an optimal deposition despite the lower flow rate. In addition, many clinicians are nowadays confronted with an important number of COPD patients who are aged >70 yrs
Read the detailed description
This study will assess the inspiratory flow rates at high levels of resistance in different stages of COPD patients. PIF will be measured by in-check method.
Commonly used for Asthma patients, the In-Check Oral Inspiratory Flow Meter is a portable hand-held inspiratory flow meter that provides an assessment of the speed of inhalation. The In-Check Oral measures inspiratory flow between 30 and 370 L/min, inspiratory flow is thought of by physicians as a sensitive marker for Chronic Obstructive Pulmonary Disease (COPD) screening. The In-Check Oral works when a patient inhales through the mouth, this will cause air to be drawn through the meter and a cursor moves along the scale to indicate the speed of inhalation. The flow rate achieved can be noted by checking the position of the cursor against the calibrated scale. The Standard In-Check Oral inspiratory flow meter can measure inspiratory flow rates in the range 30 to 370 l/min, with an accuracy of +/- 10% or 10 l/min (whichever is the greater). (A Low Range In-Check Oral Inspiratory flow meter is available by special request, measuring between 15 and 120 l/min).
All In-Check Oral meters are calibrated using an ATS pulmonary waveform generator, and the product complies with the Australian and New Zealand standards for back pressure in flow meters. As with any inhalation device checking for loose foreign objects is important. The transparent body of the In-Check Oral meter is designed to allow a visual inspection before use. The meter is manufactured from medical grade components, and is suitable for multiple patient uses when cleaned appropriately between patients. The expected life of the In-Check Oral, in normal use, is two years.

Questions about this trial
What is this clinical trial studying?
An observational study of Pulmonary Disease, run by Elpen Pharmaceutical Co. Inc. at 1 site in Greece.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PIF measurements in COPD (time frame: 0 (baseline)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01855659, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2013.
