People with cystic fibrosis (CF) who have abnormal glucose tolerance — higher-than-normal blood sugar levels after eating — are more likely to experience clinical exacerbations of worsening lung function, according to a new study. This was found to be true even for patients who don’t meet the criteria for…

People with cystic fibrosis (CF) treated with Kalydeco (ivacaftor) may have higher levels of the medication in their body than is needed for a therapeutic effect, according to a new study. “A key finding of our study revealed that some patients have higher than expected [Kalydeco] concentrations which…

Treatment with the triple-combination therapy Trikafta improved lung function and eased respiratory symptoms for school-aged children with cystic fibrosis (CF) in a Phase 3 clinical trial. “I was both surprised and delighted to see that, even this early in the disease trajectory and despite the brief treatment duration,…

Efforts to promote physical activity in people with cystic fibrosis (CF) should be holistically integrated into routine care, rather than delivered as separate interventions. “The key message resulting from the current research is that the promotion of [physical activity] in this population would be most effective as part of…

Targeting a protein called eRF3a may offer a way of treating cystic fibrosis (CF) caused by nonsense mutations, potentially opening a treatment avenue to people whose rare disease-causing mutations do not respond to current CFTR modulators, researchers reported. Their study, “Small molecule eRF3a degraders rescue…

More than half of adults with cystic fibrosis (CF) who underwent assessments of bone mineral density at a U.S. center had lower-than-expected bone density, a new study reports. “The prevalence of CF adults with lower than expected BMD [bone mineral density] in this study was found to be more…

Among babies with cystic fibrosis (CF) identified via newborn screening, there are marked delays in the start of care for children from racial and ethnic backgrounds that have historically been disadvantaged, according to a new study done in the U.S. “Because pre-symptomatic treatment is the overarching goal of [newborn…

A Phase 1 clinical trial of an experimental inhalation gene therapy for cystic fibrosis (CF) — KB407 by Krystal Biotech — was given clearance to start by the U.S. Food and Drug Administration (FDA). Expected to begin this year, the study aims to enroll 20 adults with CF who…

Infusions with a hormone called GLP-1 boosted insulin production in cystic fibrosis (CF) patients with impaired glucose tolerance, according to data from a small study. The results suggest that GLP-1 agonists — medications that mimic the hormone’s activity, but last longer in the body — may be useful as…

People with cystic fibrosis (CF) who use inhaled antibiotics are at more than three times higher risk of becoming infected with the fungus Aspergillus fumigatus, according to a new study. Study results showed no association between Aspergillus infection and lung function decline, and available data demonstrated no clear benefits of treating the…
