Cystic fibrosis (CF) is characterized by lack of hydration in the airways by impaired functioning of cystic fibrosis transmembrane conductance regulator (CFTR), leading to infection, inflammation and lung tissue damage. It is hypothesized that inhibiting the epithelial sodium channel (ENaC) in the airways in CF may enhance the mucociliary clearance (MCC) and provide clinical benefit, but numerous inhaled ENaC blockers have failed in clinical trials. Enterprise Therapeutics Ltd. is developing an inhaled ENaC blocker compound, ETD-001, for the treatment of CF.
Helios-Huaming Biopharma Co. Ltd. has described protein-arginine deiminase type-4 (PADI4) inhibitors reported to be useful for the treatment of cancer, rheumatoid arthritis, multiple sclerosis, vasculitis, systemic lupus erythematosus, ulcerative colitis, cystic fibrosis and asthma, among others.
Actelion Pharmaceuticals Ltd. has identified pyrazolopyrrolopyridazines acting as platelet-derived growth factor receptor β (PDGFR-β, PDGFRB) inhibitors reported to be useful for the treatment of pulmonary arterial hypertension.
A preclinical trial in mice and ferrets of an experimental mRNA vaccine against the H5 highly pathogenic avian influenza (HPAI) virus generated neutralizing antibodies and prevented severe illness and mortality of the animals.
Excessive inflammatory response and endothelial barrier dysfunction are the two major pathophysiological changes in acute respiratory distress syndrome (ARDS). Sphingosine-1-phosphate S1P3 receptor (S1PR3) is a G protein-coupled receptor involved in the regulation of inflammation and vascular barrier function in some diseases, but its function in ARDS is not fully understood.
Chiesi Farmaceutici SpA has divulged TGF-β receptor type-1 (TGFBR1; ALK5; SKR4; TβR-I) inhibitors reported to be useful for the treatment of idiopathic pulmonary fibrosis.
Researchers from Federation University Australia and affiliated organizations have reported data from a study that aimed to assess the therapeutic efficacy of the poly (ADP-ribose) polymerase (PARP) inhibitor olaparib in a large animal model of pulmonary fibrosis.
