The Cystic Fibrosis Foundation is once again accepting applications for its Impact Grants, a funding initiative that offers $10,000 per year for up to two years to support programs that empower people living with cystic fibrosis (CF). Applications can be submitted via an online portal and…

Biomx has raised $12 million in financing to advance BX004, a phage therapy being developed to treat bacterial infections — specifically, ones caused by Pseudomonas aeruginosa, known as P. aeruginosa for short — in people with cystic fibrosis (CF).

Boehringer Ingelheim has launched a Phase 1/2 clinical trial of BI 3720931, an inhaled gene therapy designed to treat cystic fibrosis (CF). The first-in-human trial, dubbed LENTICLAIR 1 (NCT06515002), is expected to enroll about 36 adults with CF who are not eligible for treatment with CFTR…

Young children with cystic fibrosis (CF) have less mature gut bacterial growth over time than do their typically developing peers, according to a new U.S. study. “Our findings demonstrate that the gut microbiota of infants with CF fails to undergo typical developmental maturation, instead remaining entrenched in a transitional-like…
