Streamlined Treatment of Pulmonary Exacerbations in Pediatrics
- Conditions
- Cystic Fibrosis
- Registration Number
- NCT06654752
- Lead Sponsor
- University of Washington, the Collaborative Health Studies Coordinating Center
- Brief Summary
The STOP PEDS RCT is a multicenter, parallel, open label randomized controlled trial evaluating the long-term (one year) and short-term safety and efficacy of two antibiotic treatment strategies for the management of outpatient pulmonary exacerbations (PEx) in the pediatric CF population.
- Detailed Description
The STOP PEDS pilot study demonstrated that a randomized trial of treatment strategies for mild pulmonary exacerbations (PEx) in children with CF was feasible and that assignment to a tailored therapy arm (defined below) may reduce antibiotic exposure.
Based on the research priorities identified by CF families and clinicians and the results of the pilot study, the STOP PEDS RCT is a multicenter, parallel, open label randomized controlled trial evaluating the long-term (one year) and short-term safety and efficacy of two antibiotic treatment strategies for the management of outpatient PEx in the pediatric CF population. The two treatment arms are immediate antibiotics and tailored therapy. In both arms, participants will be instructed to increase airway clearance at the onset of an eligible PEx. In the immediate antibiotics arm, they will also begin 14 days of oral antibiotics preselected by their primary CF providers, while in the tailored therapy they will only begin antibiotics if prespecified criteria for worsening symptoms or failure to improve are met.
The STOP PEDS study will enroll three cohorts. In the main cohort, children ages 6-18 on highly effective modulator therapy (HEMT) will be enrolled when well and followed for 12 months. Participants will be randomly assigned to a treatment arm and maintain that treatment assignment for all subsequent eligible PEx during their 12-month enrollment period. Two additional pilot cohorts, the preschool cohort (children ages 3 to 5 on HEMT) and the non-HEMT cohort (children ages 6-18 not eligible for HEMT), will be enrolled in parallel pilot studies. Participants will enroll when well and be followed through one randomized PEx.
Participants in the STOP PEDS RCT at selected sites will have the opportunity to enroll in optional substudies if eligible. These substudies include:
* Clinic throat swab substudy
* Home throat and nasal swab substudy
* Remote monitoring substudy (Home monitoring of lung function, vital signs, activity and sleep)

- Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the individual or the quality of the data
- Receiving an acute course of oral or IV antibiotics at the time of enrollment or within the 14 days prior to enrollment. Individuals may be re-screened ≥21 days after completion of antibiotics if they are at their baseline state of health, per self-report
- Treatment with systemic corticosteroids at enrollment or within the 14 days prior to enrollment. Individuals may be re- screened ≥21 days after completion of systemic corticosteroids if they are at their clinical baseline, per self-report
- History of solid organ transplant
- History of positive culture for Mycobacterium abscessus in the 12 months prior to enrollment
- Treatment with antibiotics for any non-tuberculous mycobacteria (NTM) at enrollment
- Three or more IV antibiotic-treated PEx in the 12 months prior to enrollment
- Treatment with chronic oral antibiotics other than azithromycin at enrollment
- Treatment with systemic corticosteroids for allergic bronchopulmonary aspergillosis (ABPA) in the 12 months prior to enrollment

- Primary Outcome Measures
Name Time Method One-year change in pulmonary function by spirometry-measured ppFEV1 1 year Compare the difference in pulmonary function between arms by evaluating change in spirometry-measured percent predicted forced expiratory volume (ppFEV1). A spirometry test measures the amount of air a person can forcibly exhale after a deep breath (forced vital capacity, or FVC) and the amount of air they can exhale in one second (forced expiratory volume in one second, or FEV1). A lower measured value compared to the reference value indicates lung disease.
- Secondary Outcome Measures
Name Time Method One-Year change in pulmonary function by LCI 1 year Compare the difference in pulmonary function between arms by evaluating change in Lung Clearance Index (LCI). LCI increases when there is lung disease, which causes ventilation inhomogeneity. LCI is calculated as the number of lung volume turnovers (cumulative expired volume divided by the functional residual capacity \[FRC\]) required to reduce end-tidal nitrogen concentration to 1/40th of the original level.
