Outcome Measures
Primary Outcome Measures
- Annualized rate of decline in morning pre-dose trough forced vital capacity (FVC) (milliliter [mL]) [Baseline through Week 26]
Secondary Outcome Measures
- Time to disease progression [Baseline through Week 26]
Disease progression is defined as absolute FVC percent predicted decline of ≥10%, or occurrence of lung transplant or all-cause death prior to Week 26.
- Annualized rate of decline in FVC percent predicted over 26 weeks [Baseline through Week 26]
- Change in St. George's Respiratory Questionnaire (SGRQ) score from Baseline to Week 26 [Baseline, Week 26]
- Change in diffusion capacity for carbon monoxide (DLco % of predicted, corrected for hemoglobin) from Baseline to Week 26 [Baseline, Week 26]
Eligibility Criteria
Criteria
Key Inclusion Criteria:
-
Documented diagnosis of IPF per the 2018 American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Society Clinical Practice Guideline (Raghu 2018).
-
Chest high-resolution computed tomography (HRCT) performed within 12 months prior to first Screening Visit and according to the minimum requirements for IPF diagnosis by central review based on participant's HRCT only (if no lung biopsy is available) or based on both HRCT and lung biopsy (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 first Screening Visit to determine eligibility, according to the same requirements as the historical HRCT. If a participant has an indeterminate usual interstitial pneumonia (UIP) pattern and their HRCT is >6 months old, if in the opinion of the Investigator their disease has progressed, an additional HRCT may be obtained and reviewed for eligibility.
-
FVC ≥45% of predicted normal at Screening Visits.
-
Forced expiratory volume in 1 second (FEV1)/FVC ≥0.7 at Screening Visits.
-
DLco ≥30% and ≤90% of predicted, corrected for hemoglobin at first Screening Visit.
Key Exclusion Criteria:
-
Abnormalities detected on electrocardiogram (ECG) of either rhythm or conduction that in the opinion of the Investigator are clinical significant. Participants with implantable cardiovascular devices (for example, 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.
-
Emphysema present on ≥50% of the HRCT, or the extent of emphysema is greater than the extent of fibrosis, according to central review of the HRCT.
-
Interstitial lung disease associated with known primary diseases (for example, connective tissue disease, sarcoidosis and amyloidosis), exposures (for example, radiation, silica, asbestos, and coal dust), or drugs (for example, amiodarone).
-
Participants who cannot meet protocol-specified baseline stability criteria.
-
Acute IPF exacerbation within 3 months prior to screening.
-
Receiving nintedanib in combination with pirfenidone
-
Receiving systemic corticosteroids equivalent to prednisone >10 milligrams (mg)/day or equivalent within 2 weeks prior to Screening.
-
Use of any of the following therapies within 4 weeks prior to Screening and during the Screening Period, or planned during the study: imatinib, ambrisentan, azathioprine, mycophenolate mofetil, cyclophosphamide, cyclosporine A, tacrolimus, bosentan, methotrexate, inhaled treprostinil, phosphodiesterase-5 inhibitors, including sildenafil (unless for occasional use), prednisone at steady dose >10 mg/day or equivalent, or other investigational therapy.
-
History of cigarette smoking or vaping within the previous 3 months.
-
Female participant who is pregnant or breastfeeding.
-
Previous exposure to study intervention or known allergy/sensitivity to study drug.
-
Receiving an investigational treatment within 28 days of randomization.
-
Inadequate IV access.
