IVA, also known as ivacaftor, is used for cystic fibrosis. It is a small molecule being developed by Vertex Pharmaceuticals for patients with cystic fibrosis who have specific ivacaftor-responsive CFTR mutations. The drug is currently in Phase 3 clinical development and is not yet approved.
IVA targets the CFTR protein, specifically addressing ivacaftor-responsive CFTR mutations. It is designed to improve the function of the defective CFTR channel in patients with cystic fibrosis, helping to restore chloride transport and reduce the symptoms of the disease.
IVA is developed by Vertex Pharmaceuticals Incorporated, which trades under the ticker VRTX. The company is conducting clinical trials to evaluate the safety and efficacy of IVA in patients with cystic fibrosis who have ivacaftor-responsive CFTR mutations.
IVA is in Phase 3 clinical development. There are three completed trials, including two Phase 3 studies and one Phase 1 study, with a total enrollment of 368 participants. The drug is investigational and has not yet received FDA approval.
IVA has been studied in three completed clinical trials. NCT02725567 evaluated safety, pharmacokinetics, and pharmacodynamics in children under 24 months. NCT03227471 was a Phase 1 study of VX-445 in healthy subjects and cystic fibrosis patients. NCT03277196 assessed long-term safety in young children.
Yes, IVA is the same as ivacaftor. The drug is referred to by its generic name ivacaftor and is being developed by Vertex Pharmaceuticals for the treatment of cystic fibrosis in patients with ivacaftor-responsive CFTR mutations.
