A medicine for lung scarring could become the first inhaled treatment of its kind. FDA accepts United Therapeutics' application.
United Therapeutics' nebulized Tyvaso for idiopathic pulmonary fibrosis (IPF) had its sNDA accepted by the FDA. The treatment showed significant efficacy in phase 3 trials, with a 111.8 mL improvement in forced vital capacity over placebo. Review is expected by late April 2027. The company aims for Tyvaso to be the first inhaled anti-fibrotic treatment for IPF if approved.
