About this study

Official title: Phase II, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Study to Evaluate the Safety, Tolerability and Efficacy of Three Dosage Regimens of MP-376 Solution for Inhalation Given for 28 Days to Stable CF Patients

Patients with cystic fibrosis (CF) suffer from chronic infections of the lower respiratory tract that can be caused by one or multiple bacteria, including Pseudomonas aeruginosa, which has been particularly problematic to eradicate and been implicated as the major cause of morbidity and mortality in CF patients. Aerosol delivery of antibiotics directly to the lung increases the local concentrations of antibiotic at the site of infection resulting in improved antimicrobial effects compared to systemic administration. Bacterial resistance to current aerosol antibiotic treatments indicate a need for improved therapies to treat CF patients with pulmonary infections caused by multi-drug resistant Pseudomonas aeruginosa and other bacteria. High concentrations of MP-376 delivered directly to the lung are projected to have antimicrobial effects on even the most resistant organisms.

Read the detailed description

This trial will be a double-blind, placebo-controlled study to evaluate the safety, tolerability and efficacy of levofloxacin administered as MP-376 of three dosage regimens given for 28 days by the aerosol route to CF patients.

Study with completed results acquired from Horizon in 2024.

What is being measured

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

  1. Change in P. Aeruginosa Density

    Patients were required to cough deeply and then spit sputum into a sterile container. The bacteria contained in the sputum sample was incubated in a laboratory and the number of P. aeruginosa colony forming units per gram of sputum (CFU/g) was determined. The difference in CFUs/g were then compared from baseline to the conclusion of the 28 day treatment period

    Measured: from baseline to end of treatment (28 days)

Secondary outcomes (5)
  1. Time to Administration of Other Anti-pseudomonal Antimicrobials

    Time to administration of other anti-pseudomonal antimicrobials in patients with at least one of the following: decreased exercise tolerance, increased cough, increased sputum/chest congestion, or decreased appetite; 25th percentile data reported

    Measured: from baseline until final study visit (up to 56 days)

  2. Percent Change in Forced Expiratory Volume in 1 Second (FEV1)

    Percent change in the amount of air the patient could exhale in 1 second

    Measured: from baseline to end of the 28-day treatment period (28 days)

  3. Change in FEV1 Percent Predicted

    Change in the predicted percent of air the patient could exhale in one second

    Measured: from baseline to the end of the treatment 28-day treatment period (28 days)

  4. Changes in Respiratory Domain Scores of Cystic Fibrosis Questionnaire - Revised (CFQ-R)

    Change in the score from 0 to 100 that a patient reports for their respiratory symptoms in the CFQ-R. An increase in score illustrates an improvement in symptoms. An increase of 4 or more is considered clinically significant

    Measured: from baseline to the end of the 28-day treatment period (28 days)

  5. Changes in Susceptability Patterns of Isolated Organisms

    All isolates of P. aeruginosa cultures grown from patient sputum samples were evaluated to see whether the minimum concentration of levofloxacin needed to inhibit growth of the bacteria (i.e., minimum inhibitory concentration; MIC) had increased; 2. The MIC50 and MIC90 values were calculated as the 50th percentile value and the 90th percentile value, respectively. Note that percentile values between dilution values were rounded up to the nearest dilution value

    Measured: from baseline until the end of the 28-day treatment period (28 days)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MP-376 in people with Cystic Fibrosis (CF), run by Amgen at 50 sites in 3 countries.

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 4 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 27 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 50 sites in United States, Germany, Netherlands. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Jun 2012). 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?

Change in P. Aeruginosa Density (time frame: from baseline to end of treatment (28 days)). 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 NCT00677365, 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 27 Dec 2024.
