Orphan Status for Concert Cystic Fibrosis Therapy
FDA has granted Concert Pharmaceuticals an orphan drug designation for CTP-656, a next-generation CFTR (cystic fibrosis transmembrane conductance regulator) potentiator being developed for treating cystic fibrosis. Last month, Concert initiated a Phase 2 trial in the U.S. evaluating the drug in cystic fibrosis patients with gating mutations. Topline results from this trial are expected by year-end 2017.
CTP-656 is a novel CFTR potentiator that may offer next-generation, once-daily dosing, according to the company. Concert is initially developing CTP-656 as a potential monotherapy treatment for cystic fibrosis due to gating mutations of the gene that encodes for CFTR, a protein that regulates components of sweat, mucus clearance and digestion.
