Full Study Name

TRK-250 – A Phase I, Double-Blind, Placebo-Controlled, Single and Multiple Inhaled Dose, Safety, Tolerability, and Pharmacokinetic Study of TRK-250 in Subjects With Idiopathic Pulmonary Fibrosis (IRB no. 54371)

The purpose of this study is to evaluate the safety and tolerability of an experimental drug called TRK-250 after single and multiple inhaled doses in patients with idiopathic pulmonary fibrosis (IPF). TRK-250 is intended to inhibit the messages in the cell that create a protein involved in lung fibrosis (scarring). This study will be conducted in two parts, single inhaled dose (Part A) and multiple inhaled doses (Part B). Subjects in both parts will be randomly assigned to receive either TRK-250 or placebo (inactive substance).
