3 terms

cystic fibrosis medical

"revolutionize the current treatment paradigm for cystic fibrosis (CF) by developing"

A genetic disease that causes the body to produce thick, sticky mucus that clogs airways and digestive passages, leading to ongoing lung infections, breathing difficulty, and problems absorbing nutrients. For investors, cystic fibrosis matters because treatments range from symptom management to pricey, targeted drugs that can change patient outcomes; progress in therapies, clinical trial results, regulatory approvals, and reimbursement decisions can significantly affect the commercial value of companies working in this area.

cftr medical

"normalize the function of the cystic fibrosis transmembrane conductance regulator (CFTR) protein"

CFTR is a gene that makes a protein acting like a tiny gate in cell membranes to control the flow of salt and water; when the gate works properly it helps keep mucus thin and organs functioning. Investors care because mutations in CFTR drive serious diseases and create demand for diagnostics, drugs and long-term treatment revenue; progress or setbacks in therapies, approvals or patents directly affect company value.

cystic fibrosis transmembrane conductance regulator medical

"novel medicines that normalize the function of the cystic fibrosis transmembrane conductance regulator (CFTR) protein"

A cystic fibrosis transmembrane conductance regulator (CFTR) is a protein that acts like a microscopic gate or faucet on cell surfaces, controlling the movement of salt and water into and out of cells. It matters to investors because mutations in CFTR cause cystic fibrosis and drive development of targeted drugs, tests, and therapies; breakthroughs or regulatory decisions around CFTR-targeting products can significantly affect the value and prospects of companies in biopharma and diagnostics.

About Sionna Therapeutics 
Sionna Therapeutics is a clinical-stage biopharmaceutical company on a mission to revolutionize the current treatment paradigm for cystic fibrosis (CF) by developing novel medicines that normalize the function of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Sionna’s goal is to deliver differentiated medicines for people living with CF that can restore their CFTR function to as close to normal as possible by directly stabilizing CFTR’s nucleotide binding domain 1 (NBD1), which Sionna believes is central to potentially unlocking dramatic improvements in clinical outcomes and quality of life for people with CF. Leveraging more than a decade of the co-founders’ research on NBD1, Sionna is advancing a pipeline of small molecules engineered to correct the defects caused by the F508del genetic mutation, which occurs in NBD1. Sionna is also developing a portfolio of complementary CFTR modulators that are designed to work synergistically with its NBD1 stabilizers to improve CFTR function.
