Who can take part

You may be able to join if

1. Male or female subject aged ≥40 years on the day of signing the Informed Consent Form (ICF).
10. Subject is capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
11. Subject and Investigator considered all medicinal treatment options and/or possibly lung transplantation prior to considering participation in the study.
2. 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).
3. HRCT confirming the diagnosis of IPF based on radiographic findings, as follows: Chest HRCT performed within 12 months prior to Screening Visit 1 and according to the minimum requirements for IPF diagnosis by central review based on subject'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 Screening Visit 1 to determine eligibility, according to the same requirements as the historical HRCT. If a subject 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.
4. Subjects are eligible if they meet either of the following criteria: a. UIP or probable UIP pattern determined by at least 2 reviewers (see Appendix 3), or b. Indeterminate UIP with an accompanying biopsy supporting UIP or probable UIP histopathology pattern. The pathology report from a locally certified pathologist will provide documentation of histopathologic criteria (see Appendix 3).

You likely can't join if

1. History of malignancy within the past 5 years unless previously treated with curative intent and approved by Medical Monitor (e.g. carcinoma in situ of the uterine cervix, basal cell carcinoma of the skin that has been treated with no evidence of recurrence, low risk prostate cancer [confined to prostate] that has been managed medically through active surveillance or watchful waiting or definitively treated more than 12 months ago with no evidence of recurrence, squamous cell carcinoma of the skin if fully resected, non-invasive ductal carcinoma in situ of the breast, and melanoma in situ).
10. Acute respiratory or systemic bacterial, viral, or fungal infection requiring systemic treatment either during Screening or prior to Screening and not successfully resolved 4 weeks prior to Screening Visit 1.
11. Class IV New York Heart Association chronic heart failure.
12. Significant pulmonary hypertension (PH) defined by any of the following: a. Previous clinical or echocardiographic evidence of significant right heart failure b. History of right heart catheterization showing a cardiac index ≤2 L/min/m² c. PH requiring parenteral therapy with epoprostenol/treprostinil
13. Cardiopulmonary rehabilitation program based on exercise training that has been completed within 6 weeks prior to Screening or planned to start within the first 6 weeks of the subject's enrollment in this study.
14. History of cigarette smoking or vaping within the previous 3 months.

Indeterminate UIP with an accompanying biopsy supporting UIP or probable UIP histopathology pattern. The pathology report from a locally certified pathologist will provide documentation of histopathologic criteria (see Appendix 3).
5. Meeting one of the following criteria for background IPF medication use: a. Subjects may be treatment-naïve to nintedanib or pirfenidone for reasons such as contraindication to nintedanib or pirfenidone or subject refusal. (Note: Initiation of nintedanib or pirfenidone and consideration of other therapies for IPF should be discussed by Investigator before study enrollment.) b. Subjects receiving pirfenidone or nintedanib for IPF must have been at a stable dose for at least 12 weeks before Screening. c. If subjects have previously taken and discontinued nintedanib or pirfenidone for any reason (eg, side effect, no therapeutic benefit, refusal of these medications by the subject), they must have discontinued such treatment ≥4 weeks prior to Screening Visit 1. Note: Discontinuation of nintedanib or pirfenidone for the sole purpose of enrollment in this study is not allowed.
6. Meeting all of the following criteria during the Screening Period: a. FVC ≥45% of predicted normal at Screening Visit 1 or Visit 2, (optional if Screening Visit 1 occurred between 6 AM and 12 PM and the subject meets the PFT criteria in this inclusion criterion #6) b.

Repeatability: Subject can perform technically acceptable PFTs meeting repeatability criteria for FVC at Screening Visits 1, 2, (optional, as above), and 3 (Appendix 2).
7. Estimated minimum life expectancy of at least 12 months for non-IPF-related disease in the opinion of the Investigator.
8. Male subjects and female subjects of childbearing potential (defined as females who are fertile, following menarche and until becoming post-menopausal unless permanently sterile) agree to use highly effective contraception measures from the time of first dose of study drug (for the male subject) or the signing of the ICF (for the female subject), during the study, and until 90 days after the last dose of study drug. Subjects agree not to donate eggs or sperm during the same period. Male subjects must use a condom and female partners of male subjects who are of childbearing potential must use a highly effective method of contraception, defined below: a. A highly effective method of contraception is one that results in a low failure rate (ie, <1% per year) when used consistently and correctly. The acceptable methods of contraception include: sexual abstinence (defined as refraining from heterosexual intercourse during the entire treatment and follow-up periods), a vasectomized partner, bilateral tubal occlusion, any effective intrauterine device/hormone-releasing system, and progesterone-only (oral, injectable, or implantable) or combined (estrogen- and progesterone-containing; oral, intravaginal, or transdermal) hormonal contraception associated with inhibition of ovulation. Note: Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea method are not acceptable methods of contraception. b. The efficacy of oral hormonal contraceptives may be compromised by vomiting and/or diarrhea or other conditions where the drug absorption may be reduced. Advise women taking oral hormonal contraceptives experiencing these conditions to use alternative highly effective contraception.
9. Subject, according to the Investigator’s best judgment, can comply with the requirements of the protocol.
