Brief Summary:
The main purpose of this study is to see how GLPG1690 works together with the current standard treatment on your lung function and IPF disease in general. The study will also investigate how well GLPG1690 is tolerated (for example if you get any side effects while on study drug).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Rate of decline of forced vital capacity (FVC) in mL. [ Time Frame: From baseline through week 52 ]
    To evaluate the efficacy of two doses of GLPG1690 in addition to local standard of care compared to placebo in subjects with Idiopathic Pulmonary Fibrosis (IPF) as evaluated by the rate of decline of FVC.


Secondary Outcome Measures :
  1. Disease progression defined as the composite endpoint of first occurrence of ≥10% absolute decline in percent predicted forced vital capacity (%FVC) or all-cause mortality. [ Time Frame: At week 52 ]
    To evaluate the impact of two doses of GLPG1690 in addition to local standard of care compared to placebo in subjects with Idiopathic Pulmonary Fibrosis (IPF) on disease progression defined as deterioration of FVC or all-cause mortality.

  2. Time to first respiratory-related hospitalization until the end of the study. [ Time Frame: From screening through study completion, a minimum of 52 weeks ]
    To evaluate the impact of two doses of GLPG1690 in addition to local standard of care compared to placebo in subjects with Idiopathic Pulmonary Fibrosis (IPF) on respiratory-related hospitalization until the end of the study.

  3. Change from baseline in the St. George's Respiratory Questionnaire (SGRQ) total score. [ Time Frame: At week 52 ]
    To evaluate the impact of two doses of GLPG1690 in addition to local standard of care compared to placebo in subjects with Idiopathic Pulmonary Fibrosis (IPF) on changes in quality of life (measured by SGRQ total score).The SGRQ is a 50-item questionnaire split into three domains: symptoms, activity and impact. Scores are weighted such that every domain score and the total score range from 0 to 100, with higher scores indicating a poorer health-related quality of life.

Ages Eligible for Study:   40 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female subject aged ≥40 years on the day of signing the Informed Consent Form (ICF).
  • A diagnosis of IPF within 5 years prior to the screening visit, as per applicable American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) guidelines at the time of diagnosis.
  • Chest high-resolution computed tomography (HRCT) historically performed within 12 months prior to the screening visit and according to the minimum requirements for IPF diagnosis by central review based on subject's HRCT only (if no lung biopsy (LB) available), or based on both HRCT and LB (with application of the different criteria in either situation). If an evaluable HRCT <12 months prior to screening is not available, an HRCT can be performed at screening to determine eligibility, according to the same requirements as the historical HRCT.
  • Subjects receiving local standard of care for the treatment of IPF, defined as either pirfenidone or nintedanib, at a stable dose for at least two months before screening, and during screening; or neither pirfenidone or nintedanib (for any reason). A stable dose is defined as the highest dose tolerated by the subject during those two months.
  • The extent of fibrotic changes is greater than the extent of emphysema on the most recent HRCT scan (investigator-determined).
  • Meeting all of the following criteria during the screening period: FVC ≥45% predicted of normal, Forced expiratory volume in 1 second (FEV1)/FVC ≥0.7, diffusing capacity of the lung for carbon monoxide (DLCO) corrected for Hb ≥30% predicted of normal.
  • Estimated minimum life expectancy of at least 30 months for non IPF related disease in the opinion of the investigator.
  • Male subjects and female subjects of childbearing potential agree to use highly effective contraception/preventive exposure measures from the time of first dose of investigational medicinal product (IMP) (for the male subject) or the signing of the ICF (for the female subject), during the study, and until 90 days (male) or 30 days (female) after the last dose of IMP.
  • Able to walk at least 150 meters during the 6-Minute Walk Test (6MWT) at screening Visit 1; without having a contraindication to perform the 6MWT or without a condition putting the subject at risk of falling during the test (investigator's discretion). The use of a cane is allowed, the use of a stroller is not allowed at all for any condition. At Visit 2, for the oxygen titration test, resting oxygen saturation (SpO2) should be ≥88% with maximum 6 L O2/minute; during the walk, SpO2 should be ≥83% with 6 L O2/minute or ≥88% with 0, 2 or 4 L O2/minute.

Exclusion Criteria:

  • History of malignancy within the past 5 years (except for carcinoma in situ of the uterine cervix, basal cell carcinoma of the skin that has been treated with no evidence of recurrence, prostate cancer that has been medically managed through active surveillance or watchful waiting, squamous cell carcinoma of the skin if fully resected, and Ductal Carcinoma In Situ).
  • Clinically significant abnormalities detected on ECG of either rhythm or conduction, a QT interval corrected for heart rate using Fridericia's formula (QTcF) >450 ms, or a known long QT syndrome. Patients with implantable cardiovascular devices (e.g. pacemaker) affecting the QT interval time may be enrolled in the study based upon investigator judgment following cardiologist consultation if deemed necessary, and only after discussion with the medical monitor.
  • Acute IPF exacerbation within 6 months prior to screening and/or during the screening period. The definition of an acute IPF exacerbation is as follows: Previous or concurrent diagnosis of IPF; Acute worsening or development of dyspnea typically < 1 month duration; Computed tomography with new bilateral ground-glass opacity and/or consolidation superimposed on a background pattern consistent with usual interstitial pneumonia pattern and deterioration not fully explained by cardiac failure or fluid overload.
  • Lower respiratory tract infection requiring treatment within 4 weeks prior to screening and/or during the screening period.
  • Interstitial lung disease associated with known primary diseases (e.g. sarcoidosis and amyloidosis), exposures (e.g. radiation, silica, asbestos, and coal dust), or drugs (e.g. amiodarone).
  • Diagnosis of severe pulmonary hypertension (investigator determined).
  • Unstable cardiovascular, pulmonary (other than IPF), or other disease within 6 months prior to screening or during the screening period (e.g. acute coronary disease, heart failure, and stroke).
  • Had gastric perforation within 3 months prior to screening or during screening, and/or underwent major surgery within 3 months prior to screening, during screening or have major surgery planned during the study period.
  • History of nintedanib-related increase in ALT and/or AST of >5 x upper limit of the normal range (ULN) and increased susceptibility to elevated LFT; moderate to severe hepatic impairment (Child-Pugh B or C) and/or abnormal liver function test (LFT) at screening, defined as aspartate aminotransferase (AST), and/or alanine aminotransferase (ALT), and/or total bilirubin ≥1.5 x upper limit of the normal range (ULN), and/or gamma glutamyl transferase (GGT) ≥3 x ULN. Retesting is allowed once for abnormal LFT.
  • Abnormal renal function defined as estimated creatinine clearance, calculated according to Cockcroft-Gault calculation (CCr) <30 mL/min. Retesting is allowed once.
  • Use of any of the following therapies within 4 weeks prior to screening and during the screening period, or planned during the study: warfarin, imatinib, ambrisentan, azathioprine, cyclophosphamide, cyclosporine A, bosentan, methotrexate, sildenafil (except for occasional use), prednisone at steady dose >10 mg/day or equivalent.
