About this study

Official title: APPLAUD: A Double-Blind, Randomized, Placebo-Controlled, Phase II Study of the Efficacy and Safety of LAU-7b in the Treatment of Cystic Fibrosis in Adults

An International Phase II, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of LAU-7b administered once-daily for 6 months for the treatment of CF.

Read the detailed description

An International Phase II, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of LAU-7b administered once-daily for 6 months for the treatment of CF. All patients will remain on their CF standard-of-care treatments over the trial duration.

The goal for the treatment with LAU-7b in CF is to preserve lung function by reducing the persistent inflammation in the lung and to improve its capacity to defend against resistant bacteria such as Pseudomonas aeruginosa.

The treatment regimen will consist of 6 consecutive "dosing cycles" of 21 days each, spaced by study drug-free periods of 7 days. A total of 136 eligible adult patients with CF will be randomized to receive 300 mg LAU-7b or placebo in a 1:1 ratio. The participation in the study will last about 7 months.

What is being measured

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

  1. Absolute Change in Percent Predicted Forced Expiratory Volume in 1 Second (FEV1%)

    Standardized, serial FEV1 measurements were performed during the trial by the clinical sites using standardized spirometers. All spirometry measurements were centrally read and validated by the spirometry provider, Vitalograph. The outcome measure is presented using the Least Squares Mean at the Week 24 time point and the Least Squares Mean of all post-baseline time points through Week 24 averaged.

    Measured: From baseline to 24 weeks

  2. Summary of Treatment Emergent Adverse Events With ≥ 10% Incidence

    This was assessed through adverse event monitoring at all visits, including spontaneously reported events and those obtained through serial probing of the subjects, and from safety laboratory tests

Secondary outcomes (14)
  1. The Proportion of Patients Achieving Normalization of the Arachidonic Acid, Docosahexaenoic Acid and Their Ratio in Phospholipids

    Assessed through 4 blood sampling occasions during the trial. Plasma samples were analyzed using a validated LC/MS method and corrected for phospholipid content. Highest proportion of normalization during treatment was determined versus analyte ranges obtained from a group of 20 healthy, non-CF individuals.

    Measured: From baseline to 28 weeks

  2. The Absolute Change in FEV1 Percent Predicted at 3, 7, 11, 15, 24 and 28 Weeks Into the Trial

    Standardized, serial FEV1 measurements were performed during the trial by the clinical sites using standardized spirometers. All spirometry measurements were centrally read and validated by the spirometry provider, Vitalograph.

    Measured: From baseline to 3, 7, 11, 15, 24 and 28 weeks into the trial

  3. The Relative (%) Change in FEV1 Percent Predicted at 3, 7, 11, 15, 24 and 28 Weeks Into the Trial

    Standardized, serial FEV1 measurements were performed during the trial by the clinical sites using standardized spirometers. All spirometry measurements were centrally read and validated by the spirometry provider, Vitalograph.

    Measured: From baseline to 3, 7, 11, 15, 24 and 28 weeks into the trial

  4. The Time to First Protocol-Defined Pulmonary Exacerbation

    Reports of IV antibiotics-treated pulmonary exacerbations during the trial that meet the Fuch's criteria and after the first treatment cycle.

    Measured: From baseline to 28 weeks

  5. The Number Per Subject of Protocol-Defined Pulmonary Exacerbations (PEx) During the Trial

    The number per subject of Protocol-Defined IV antibiotics-treated pulmonary exacerbations (events) during the trial that meet the Fuch's criteria. Also presented are the number per subject of IV antibiotics-treated pulmonary exacerbations and combined number per subject of IV- or Oral antibiotics-treated pulmonary exacerbations during the trial. Excluded are exacerbations occurring during the first treatment cycle.

    Measured: From baseline to 28 weeks

  6. The Time to First Change and Usage of Antibiotic (Other Than Chronic Inhaled Antibiotics Already Started Prior to Trial or Oral Chronic Azithromycin)

    The time to first change and usage of IV antibiotics to treat pulmonary exacerbations during the trial. Excluded are exacerbations occurring during the first treatment cycle.

    Measured: From baseline to 28 weeks

  7. Usage (Number of Antibiotic Treatments) of Antibiotic (Other Than Chronic Inhaled Antibiotics Already Started Prior to Trial or Oral Chronic Azithromycin)

    Usage (number of antibiotic treatments per subject) of IV antibiotics to treat pulmonary exacerbations during the trial. Excluded are exacerbations occurring during the first treatment cycle.

    Measured: From baseline to 28 weeks

  8. Usage (Days) of Antibiotic (Other Than Chronic Inhaled Antibiotics Already Started Prior to Trial or Oral Chronic Azithromycin)

    Usage (days) of IV antibiotics to treat pulmonary exacerbations during the trial. Excluded are exacerbations occurring during the first treatment cycle.

    Measured: From baseline to 28 weeks

  9. The Change From Baseline of Systemic Markers of Inflammation in Blood

    This was assessed through scheduled blood sampling during the trial on three occasions. Both ITT and PP populations results presented. Samples were analyzed using validated analytical methods.

    Measured: Change from baseline to Week 24

  10. The Change From Screening of the Body Weight

    This was assessed through serial weighing during the trial. Measurements performed at clinical sites using calibrated balances.

    Measured: From screening to 28 weeks

  11. The Change From Screening of the Body Mass Index (BMI)

    This was assessed through serial weighing during the trial and calculation of BMI. Measurements performed at clinical sites using calibrated balances.

    Measured: From screening to 28 weeks

  12. The Overall Change From Screening of the Pseudomonas Aeruginosa Density (Colony Forming Units) in the Sputum

    This was assessed through induced sputum (and spontaneously obtained during COVID-19 pandemic) on 3 occasions during the trial. Samples were analyzed at a central laboratory. An area under the curve (AUC from baseline to Week 24 inclusive) of colony forming unit/mL is calculated.

    Measured: From screening to Week 24

  13. The Impact (From Baseline) on Overall Health, Daily Life, Perceived Well-being and Symptoms Measured With the Cystic Fibrosis Questionnaire-Revised (CFQ-R)

    This was assessed through administration of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at four planned times during the trial. The CFQ-R respiratory sub-score (range 0-100) was extracted and analyzed. The Minimum Clinically Important Difference (MCID) for the respiratory sub-score is 4 units. A higher score means a better outcome.

    Measured: From baseline to 24 weeks

  14. The Change in Metabolipidomic Profile and in Markers of Oxidative Stress in Blood

    This was assessed through serial blood sampling during the trial. Samples were analyzed using validated methods at specialized laboratories.

    Measured: From baseline to 24 weeks
