Rethinking Early Airway Clearence Therapies (REACT)

6. července 2026 aktualizováno: Nicole Hamblett

The REACT trial consists of two parallel, randomized studies; the Hypertonic Saline Study and the Dornase Alfa Study.

Health outcomes among people with cystic fibrosis (CF) have been steadily improving, most recently with the advent of highly effective modulator therapy (HEMT). While therapies like hypertonic saline (HS) and dornase alfa (DA) improved outcomes in the past, they are often burdensome. Now that almost 90% of the North American CF population is being treated with elexacaftor/tezacaftor/ivacaftor (ETI) or vanzacaftor/tezacaftor/deutivacaftor (VTD), this trial will evaluate whether these newer treatments make daily HS or DA unnecessary. The trial begins with a 6-week run-in period where participants continue ETI or VTD but stop using HS and DA. Eligible participants are then assigned to either the HS Study or the DA Study for one year. Within those groups, they are randomized to either daily use of HS or DA or as needed use only during respiratory illnesses. The study aims to find out if lung health is similar between children and teens taking HEMT who use HS or DA treatments daily and those who use HS or DA treatments only when they are sick.

Detailní popis

Health outcomes among people with cystic fibrosis (CF) have been steadily improving for decades through guideline-directed multi-disciplinary clinical care models, expanding CF-specific therapies, and, most recently, the advent of highly effective modulator therapies (HEMT). Chronic therapies such as hypertonic saline (HS) and dornase alfa (DA) were associated with improved outcomes in the pre-modulator era but are also burdensome and costly. Now that almost 90% of the North American CF population is being treated with elexacaftor/tezacaftor/ivacaftor (ETI) or vanzacaftor/tezacaftor/deutivacaftor (VTD), many in the CF community are asking if chronic inhaled therapies such as HS or DA can be stopped or not started (in young children). Indeed, many people with CF stably on ETI are already stopping or reducing these chronic inhaled mucoactive therapies (CIMT) without an evidence base to guide shared decision-making.

The REACT trial is a platform trial consisting of two parallel prospective, multicenter, randomized, open-label studies: the Hypertonic Saline (HS) Study and the Dornase Alfa (DA) Study. In the Hypertonic Saline (HS) Study, participants will be randomized to twice-daily inhaled HS or as-needed HS (with acute respiratory illnesses, if considered indicated) for one year. In the Dornase Alfa (DA) Study, participants will be randomized to daily inhaled DA or as-needed DA (with acute respiratory illnesses, if considered indicated) for one year.

Study participation will begin with a 6-week run-in period, during which participants who currently use HS, DA, or both will be instructed to stop these therapies; those who do not use chronic inhaled mucoactive therapies (CIMT) will be instructed to remain off these therapies. At the end of the run-in, eligible participants will be enrolled and assigned first to the HS or DA Study and then randomized to study arm. Participants who use only HS or no CIMT at study entry will be assigned to the HS Study. Those who use DA only at study entry will be assigned to the DA Study. Those who use both HS and DA will be randomly assigned to the HS or DA Study. Participants will be instructed to continue their mechanical airway clearance and inhaled antibiotics (if applicable) as prescribed at study entry. Those who were on both HS and DA at study entry will be instructed to only use the inhaled mucoactive agent to which they have been assigned (HS or DA). Participants randomized to the as-needed arm will be allowed to use the study inhaled agent (HS or DA) temporarily, if considered indicated, with acute respiratory illnesses. Participants in either arm will be allowed to (re)introduce chronic daily therapy if felt to be indicated by the treating physician.
