  • TiotropiumDrug

  • SalmeterolDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The change from baseline (Visit 2) in the PaO2 area under the curve (AUC) for the time period 0 to 105 minutes obtained through arterial blood gases (ABGs) at the end of each treatment period.

    Measured: up to day 90

Secondary outcomes (8)
  1. Maximum decline in PaO2 from baseline

    Measured: up to day 90

  2. Maximum increase in alveolar-arterial oxygen gradient from baseline

    Measured: up to day 90

  3. Change from baseline (Visit 2) in FEV1 prior to insertion of catheter and 15 minutes post removal of catheter

    Measured: up to day 90

  4. Change from baseline (Visit 2) in FVC prior to insertion of catheter and 15 minutes post removal of catheter

    Measured: up to day 90

  5. Rescue medication use

    Measured: up to day 90

  6. COPD symptom score

    Measured: up to day 90

  7. Occurrence of adverse events

    Measured: up to day 90

  8. Pulse rate and sitting blood pressure in conjunction with spirometry

    Measured: up to day 90

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tiotropium and Salmeterol in people with Pulmonary Disease, Chronic Obstructive, run by Boehringer Ingelheim at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 5 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

The change from baseline (Visit 2) in the PaO2 area under the curve (AUC) for the time period 0 to 105 minutes obtained through arterial blood gases (ABGs) at the end of each treatment period. (time frame: up to day 90). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Nov 2013.
