Standardizing Treatments for Pulmonary Exacerbations - Aminoglycoside Study
Purpose
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?

- Allocation
- Randomized
- Intervention Model
- Parallel Assignment
- Intervention Model Description
- The aminoglycoside study will compare treatment of an IV β-lactam and aminoglycoside (AG) versus an IV β-lactam only (non-AG). Individuals will be randomly assigned in a 1:1 fashion to receive either the AG or non-AG intervention for a planned 14 day course of IV antibiotics. IV antibiotic treatments for each intervention arm will be selected by the treating physician following standard of care.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Other β-lactam Only (Non-AG) |
Participants 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. |

Other β-lactam and Aminoglycoside (AG) |
Participants randomized to this arm will be prescribed a standard of care intravenous (IV) β-lactam and aminoglycoside selected by their treating physician. |

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.
