NACFC 2023: Sionna’s Series 2 molecules can restore CFTR protein

Sionna Therapeutics’ second-generation molecules, combined with standard CFTR modulators, fully restored the production and function of the CFTR protein with the most common mutation that causes cystic fibrosis (CF), according to preclinical data. The Series 2 molecules, SION-719 and SION-451, are undergoing investigational new drug (IND) enabling…

Complex genetic diversity found among P. aeruginosa strains

A high degree of genetic diversity was found among strains of Pseudomonas aeruginosa bacteria initially infecting the lungs of people with cystic fibrosis (CF), a study reports. Over a seven-year follow-up, the majority of CF patients experience a recurrence of the bacteria, with one-third of those being infected…

Journaling improves the mental health of teens with CF

Bacterial airway infection in CF tough to eradicate: 20-year study

More than half of the infections caused by the Burkholderia cepacia complex (BCC), a bacteria known to cause serious complications in people with cystic fibrosis (CF), were successfully eradicated, a 20-year study reported. Despite some CF patients testing negative following initial treatment for more than two years, however, subsequent…

Telemedicine comparable to standard care in managing CF: Study

Telemedicine programs for managing cystic fibrosis (CF) were at least as effective as standard in-clinic care, according to a review study. Adhering to treatment regimens and patient satisfaction with telemedicine improved significantly across most studies examined, and most participants favored continuing with telemedicine. The review study, “…

New target may aid antibiotics in treating M. abscessus infection

A newly identified therapeutic target showed a potential to enhance the effectiveness of antibiotics against resistant Mycobacterium abscessus (Mabs) lung infection, a damaging complication in people with cystic fibrosis (CF), researchers report.
