Safety, Tolerability, and Pharmacokinetic Study of TRK-250 for Patients With Idiopathic Pulmonary Fibrosis
Purpose
TRK-250 is a nucleic acid medicine that inhibits the progression of pulmonary fibrosis by selectively suppressing the expression of transforming growth factor-beta 1 (TGF-β1) protein, at the gene expression level. This study is a double-blind, randomized, placebo-controlled Phase I study. The primary objective of the study is to assess the safety and tolerability of single and multiple inhaled doses of TRK-250 in subjects with idiopathic pulmonary fibrosis (IPF).
Condition
- Idiopathic Pulmonary Fibrosis
Eligibility
- Eligible Ages
- Between 40 Years and 80 Years
- Eligible Genders
- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- Clinical, radiographic, and histologic features consistent with the diagnosis of IPF - SpO2 ≥90% at rest by pulse oximetry while breathing ambient air. - FVC ≥50% of predicted. - FEV1 ≥50% of predicted. - Ratio of FEV1 to FVC ≥0.7. - DLCO corrected for hemoglobin 30% to 79% of predicted, inclusive.
Exclusion Criteria
- History of acute exacerbation of IPF or respiratory tract infection within 3 months prior to Screening. - Planned surgery during the study. - History of malignant tumor within 5 years prior to Screening. - History of emphysema or clinically significant respiratory diseases (other than IPF). - Other known causes of interstitial lung disease (eg, drug toxicities, environmental exposures, connective tissue diseases). - End-stage fibrotic disease expected to require organ transplantation within 6 months. - Taking a systemic corticosteroid, cytotoxic therapy, vasodilator therapy for pulmonary hypertension, or unapproved treatment for IPF within 4 weeks prior to Screening. (Treatment with pirfenidone or nintedanib, though not both concurrently, is permitted, provided that the subject has been on a stable dose for at least 4 weeks prior to Screening and it is anticipated the dose will remain unchanged throughout enrollment.)
