What the trial was testing
The trial enrolled 77 patients with cystic fibrosis. The study was sponsored by Vertex Pharmaceuticals Incorporated and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Lung function improved by 16 percentage points in patients with F/F mutations, compared to no change with the current standard treatment.
The Lancet. Respiratory medicine · 2023 · NCT03911713
These findings — that patients with F/F mutations who took the new three-drug combination improved lung function by 16 percentage points in four weeks. — were published in the The Lancet. Respiratory medicine and represent the headline result of the study.
Researchers tracked outcomes across 77 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with cystic fibrosis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This treatment showed real promise for people with certain cystic fibrosis mutations who haven't had enough benefit from existing drugs. It's taken just once a day instead of twice, which could make it easier to stick with. This is early-stage research, so ask your doctor about when this might be available or what approved options you can try now.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Surrogate Markers of Response to New Therapies in Cystic Fibrosis Patients
The purpose of this study is to determine which biological marker, or association of biological markers, best predict clinical response of cystic fibrosis patients to CFTR modulators.
High-Intensity Interval Exercise in Bronchiectasis Patients
The aim of our study is to investigate the effect of high-intensity interval exercise (HIIE) on the symptoms of bronchiectasis in patients with the disease. The main questions it aims to answer are: 1. Does HIIE improve respiratory function in patients with bronchiectasis? 2. Does HIIE increase functional capacity, peripheral muscle strength, and quality of life in patients with bronchiectasis? 3. Does HIIE reduce the severity of dyspnea, cough symptoms, and fatigue in patients with bronchiectasis? The study was designed as a randomized controlled trial. Participants were divided into two groups: intervention and control. Participants will: The intervention group will receive HIIE training three days a week along with airway clearance techniques. The control group would receive only airway clearance techniques. Airway clearance techniques will be provided clinically (three days a week) and at home, according to the needs of the individuals each day of the week.
