(STOP PEDS RCT)
What this study is about
The STOP PEDS RCT is a conducted at multiple hospitals, parallel, open label randomly assigned controlled trial evaluating the long-term (one year) and short-term safety and effectiveness of two antibiotic treatment strategies for the management of outpatient pulmonary exacerbations (PEx) in the pediatric CF population.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- For main cohort and non-HEMT cohort: age 6 to \<19 years
- For preschool cohort: age 3 to \<6 years
- Documentation of a CF diagnosis as evidenced by one or more clinical features consistent with the CF phenotype and one or more of the following criteria:
- sweat chloride ≥ 60 mEq/liter
- two disease-causing variants in the cystic fibrosis transmembrane conductive regulator (CFTR) gene
- Written informed consent (and assent when applicable) obtained from participant or participant's legal representative and ability of participant to comply with the requirements of the study
- Highly Effective Modulator Therapy
- For main cohort and preschool cohort: Taking HEMT for at least 3 months at enrollment
- For non-HEMT cohort: not eligible for HEMT based on CFTR genotype or eligible but not taking for at least 3 months and no plans to start HEMT in the next year, and also not taking tezacaftor-ivacaftor or lumacaftor-ivacaftor for at least 3 months
- For main cohort and non-HEMT cohort: able to perform acceptable and reproducible spirometry
- For main cohort and non-HEMT cohort: ppFEV1 ≥ 50% predicted at enrollment based on the Global lung Initiative (GLI) reference equations
- Ability to receive text messages and access the internet
Exclusion criteria
- 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

- 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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
