The primary objective of this study is to evaluate the long term safety and tolerability of simtuzumab (GS-6624) in participants with idiopathic pulmonary fibrosis (IPF) who had previously participated in Gilead clinical trial AB0024-201.

Condition Intervention Phase
Idiopathic Pulmonary Fibrosis Drug: Simtuzumab Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2, Long-Term Safety Study of GS-6624 in Adult Subjects With Idiopathic Pulmonary Fibrosis (IPF)

Primary Outcome Measures:
  • Overall Safety Profile of Simtuzumab [ Time Frame: 30 days post last study treatment (up to 165 weeks) ]
    The overall safety of simtuzumab was assessed as the percentage of participants experiencing adverse events (AEs; Serious AEs, Grade 3 or 4 AEs, AEs related to simtuzumab, and AEs leading to discontinuation of simtuzumab), treatment-emergent chemistry and hematology abnormality.

Secondary Outcome Measures:
  • Relative Change From Baseline in FVC % Predicted at Weeks 72 and 144 [ Time Frame: Weeks 72 and 144 ]
    • FVC was a pulmonary function test, and was defined as the volume of air that can forcibly be blown out after taking a full breath.
    • Least square means were from mixed model for repeated measures (MMRM) model including baseline FVC % predicted and visit including all data up to Week 144.

  • Relative Change From Baseline in DLCO % Predicted at Weeks 72 and 144 [ Time Frame: Weeks 72 and 144 ]
    • DLCO was a measurement to determine the extent to which oxygen passes from the air sacs of the lungs into the blood.
    • Least square means were from MMRM model including baseline DLCO % predicted and visit including all data up to Week 144.

  • All-cause Mortality [ Time Frame: Up to 165 weeks ]
    All-cause mortality was assessed as a number of participants who died from any cause.

  • Relative Change From Baseline in Serum Lysyl Oxidase-like 2 (sLOXL2) Levels at Weeks 72 and 120 [ Time Frame: Weeks 72 and 120 ]
