A Phase 1b, Multicenter, Randomized, Double-blind, Placebo-controlled Multiple Ascending Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of PMG1015 in Idiopathic Pulmonary Fibrosis (IPF) Subjects
This is a phase 1b randomized, double-blind, placebo-controlled, multiple ascending doses (MAD) study of PMG1015 in idiopathic pulmonary fibrosis (IPF) subjects. This study aims to evaluate the safety, tolerability, pharmacokinetics and immunogenicity of PMG1015 after MAD.
• Diagnosis of IPF as defined by current American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) Clinical Practice Guidelines for IPF (2022) (Pathological examination refers to transbronchial lung cryobiopsy or surgical/pleuroscopic lung biopsy);
• Forced vital capacity percent predicted (FVCpp) ≥45% at screening;
• Diffusing capacity of the lung for carbon monoxide (DLCO; corrected for haemoglobin) from 30% to 90% of the predicted, inclusive at screening;
• Subjects not receiving any approved IPF treatment (pirfenidone or nintedanib) within 1 month before enrollment for any reasons
