Idiopathic pulmonary fibrosis (IPF) is a rare, progressive life-threatening disease that is characterized by exertional dyspnea and persistent dry cough.

Cough in IPF is both a presenting and a complicating clinical feature, which affects approximately three quarters of IPF cases. It is often a debilitating symptom that adversely affects quality of life (QoL) and is usually refractory to medical therapy.

Inhaled RVT-1601 (formerly, PA101B), a new inhalation formulation of cromolyn sodium delivered via the eFlow® Closed System (CS) nebulizer, is being evaluated in this Phase 2b study for the treatment of persistent cough in patients with IPF.
