Plain-language summary
Bronchiolitis Obliterative Syndrome (BOS) is the primary noninfectious pulmonary complication after hematopoietic stem cell transplantation (HSCT) and usually carries a poor prognosis. It occurs in about 10% of children underwent HSCT. The National Institutes of Health (NIH) published guidelines and criteria for the diagnosis of BOS. BOS defined by spirometric criteria according to modified NIH consensus guidelines: FEV1 \< 75% predicted and a greater than 10% decline from pretransplant baseline, and FEV1/FVC \<0.7 (FCV: Forced Vital Capacity). Nevertheless Cheng and al. indicate that the magnitude of FEV1 decline before diagnosis exceeded the diagnostic requirement of a greater than 10% decline compared with baseline FEV. Moreover, the decline in FEV1 prior to BOS diagnosis appeared to occur within 6 months for those patients. Recent studies suggest that any intervention should be targeted during the FEV1 decline, and before the diagnosis of BOS. For this, inhalated treatment are used: Bergeron et al. reported improvements in symptoms as well in FEV1 one month followed treatment including formoterol and budesonide in a prospective trial including adults (12% increase of FEV1 for 62% adults). Williams and al. in another prospective adult's cohort, showed that the association between fluticasone, montelukast and azythromycin was associated with stable lung function, reduced systemic corticosteroids, and improved quality of life at 3 months for adults with BOS.
In our national French prospective cohort which include 300 children with HSCT from 2014 to 2017 (RESPPEDHEM Programme Hospitalier de Recherche Clinique 2012), 35% of children presented a decline of FEV1≥ 10% without BOS criteria (FEV1 \< 75% and FEV1/FVC \<0.7). Among them, some received combination of corticoids and long acting beta agonists for 6 months. Children with this type of inhalated treatment improved their FEV1 to 88.1% predicted while children without any treatment have a FEV1 at 80.7% predicted. Our hypothesis is that association of Fluticasone Propionate and Salmeterol can be used as a treatment of the decline of FEV1 for children and so prevent BOS.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
