Standardizing Treatments for Pulmonary Exacerbations - Aminoglycoside Study

Phase 4

Registration Number

Brief Summary

The purpose of this study is to look at pulmonary exacerbations in people with cystic fibrosis (CF) that need to be treated with antibiotics given through a tube inserted into a vein (intravenous or IV). A pulmonary exacerbation is a worsening of respiratory symptoms in people with CF that needs medical intervention. Both doctors and CF patients are trying to understand the best way to treat pulmonary exacerbations. This study is trying to answer the following questions about treating a pulmonary exacerbation:

* Do participants have the same improvement in lung function and symptoms if they are treated with one type of antibiotic (called beta-lactams or β-lactams) versus taking two different types of antibiotics (tobramycin and β-lactams)?

* Is taking one type of antibiotic just as good as taking two types?

Detailed Description

Cystic Fibrosis Foundation (CFF) treatment guidelines for the management of pulmonary exacerbations (PEx) identified evidence gaps in current clinical best practices. The STOP program offers a platform for the conduct of controlled trials to develop the evidence base in order to define clinical best practices. The interventional Aminoglycoside Study (AG Study) will be a prospective, multi-center, parallel group, randomized (1:1 ratio), open-label, superiority study of intravenous aminoglycoside and β-lactams versus intravenous β-lactams only. Randomization will occur at Visit 1. The primary objective of this platform trial is to evaluate the efficacy and safety of differing treatments in CF PEx during a planned 14 day course of IV antimicrobials. Primary efficacy will be evaluated as the difference in mean Percent Predicted Forced Expiratory Volume in 1 Second (ppFEV1) changes from Visit 1 to Visit 2 (Day 28 ± 2 days) between intervention arms.

β-lactam Only (Non-AG)Beta-lactam antibioticParticipants randomized to this arm will be prescribed a standard of care intravenous (IV) β-lactam as selected by their treating physician. Treatment must not include an IV aminoglycoside.
β-lactam and Aminoglycoside (AG)Beta-lactam antibioticParticipants randomized to this arm will be prescribed a standard of care intravenous (IV) β-lactam and aminoglycoside selected by their treating physician.
β-lactam and Aminoglycoside (AG)AminoglycosideParticipants randomized to this arm will be prescribed a standard of care intravenous (IV) β-lactam and aminoglycoside selected by their treating physician.
Primary Outcome Measures
NameTimeMethod
Absolute Change in FEV1 % Predicted at Week 4 in Aminoglycoside (AG) StudyFour weeks

Difference between aminoglycoside (AG) study intervention arms (AG - Non-AG) in the absolute change in FEV1 % predicted from Week 0 (Day 0) to Week 4 (Day 28 ± 2 days)

Incidence of Adverse Events (AEs) in Aminoglycoside (AG) Study Intervention ArmsSix Weeks

Difference between aminoglycoside (AG) study intervention arms (AG - Non-AG) in the proportion of participants with at least one AE from Week 0 (Day 0) to Week 6 (Day 44 ± 2 days).

Secondary Outcome Measures
NameTimeMethod
Absolute Change in CFRSD-CRISS Score at Week 4 in Aminoglycoside (AG) StudyFour weeks

Difference between aminoglycoside (AG) study intervention arms (AG - Non-AG) in the absolute change in respiratory symptoms, as measured by the CF Respiratory Symptoms Diary-Chronic Respiratory Infection Symptom Score (CFRSD-CRISS) from Week 0 (Day 0) to Week 4 (Day 28 ± 2 days). The CFRSD-CRISS is derived from a set of questions asking a participant to state the extent of their 8 respiratory symptoms: difficulty breathing, feverishness, tiredness, chills or sweats, coughing, coughing up mucus, tightness in the chest and wheezing. Each respiratory symptom is assigned a score from 0-4 based on the response, with zero corresponding to the absence of the symptom and four corresponding to symptom being present 'a great deal' or 'extremely'. A summed score (range from 0-24) is calculated for each participant and converted to a final score with a range of 0 to 100, where the lowest scores indicate improvement of symptoms.
