About this study

Official title: A Randomized Trial of Doxycycline to Reduce Sputum MMP-9 Activity in Adult CF Patients Hospitalized for Pulmonary Exacerbations

The purpose of this study is to examine the role of a well-known and well-tolerated antibiotic, doxycycline, in the treatment of cystic fibrosis patients who are hospitalized. This antibiotic does not effectively treat the bacteria in airways of cystic fibrosis patients, but may reduce the activity of inflammatory molecules in the disease.

Read the detailed description

One molecule that is inhibited by doxycycline is matrix metalloprotease-9, which is emerging as an important mediator of lung inflammation and damage in cystic fibrosis. We hypothesize that the addition of treatment with doxycycline in CF inpatients will reduce MMP-9 activity and inflammatory markers in the sputum of cystic fibrosis patients compared to CF patients not treated with doxycycline.

What is being measured

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

  1. Number of Adverse Events

    Examines tolerability and safety with focus on adverse events (AEs) and serious adverse events (SAEs)

    Measured: 1 month from enrollment

  2. Matrix Metalloprotease-9 (MMP-9) Protein Levels in Sputum

    Mean sputum matrix metalloprotease-9 (MMP-9) levels measured at the end of therapy

    Measured: 8 days past baseline

Secondary outcomes (2)
  1. Mean Sputum Matrix Metalloprotease-9 (MMP-9) Activity End of Treatment

    Measurement of endogenous active matrix metalloprotease-9 (MMP-9) in the sputum

    Measured: 8 days

  2. Mean Change in Pulmonary Function Over Treatment Duration

    Observe change in FEV1% predicted from beginning to end of study

    Measured: Baseline to end of inpatient clinical exacerbation (average 14 days)

Questions about this trial

What is this clinical trial studying?

A study testing Doxycycline in people with Cystic Fibrosis, run by University of Alabama at Birmingham at 1 site 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?

The sponsor lists 2 inclusion and 10 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 6 Mar 2017. 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 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 6 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Adverse Events (time frame: 1 month from enrollment). The study lists 2 primary outcomes in all. 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 NCT01112059, which also lists 1 linked publication.

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 6 Mar 2017.
