Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 9

  1. 01. Able to understand and sign a written informed consent form (ICF) consistent with International Council for Harmonisation (ICH) Guideline for Good Clinical Practice (GCP) and local laws prior to study enrollment.
  2. 02. Able to understand the importance of adherence to study treatment and the study protocol, willing to follow all study requirements, including the concomitant medication restrictions, throughout the study, and willing and able to fully attend and complete all study visit days in the clinic.
  3. 03. Aged ≥40 years at Visit 1 (Screening).
  4. 04. Chest HRCT performed within 52 weeks prior to Visit 1 (Screening) with results available for documentation in site files.
  5. 05. A diagnosis of IPF, as confirmed by the Investigator via written medical records, according to American Thoracic Society (ATS)/ European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Asociación Latinoamericana de Tórax (ALAT) IPF guideline (Raghu et al., 2022) within 5 years of Visit 1 (Screening). If IPF diagnosis occurred greater than 5 years before Visit 1 (Screening), the Investigator should review eligibility with the Sponsor Medical Monitor.
  6. 06. Combination of HRCT pattern, and if available, surgical lung biopsy pattern, as assessed by the Investigator, consistent with a diagnosis of IPF.
  7. 07. DLCO (corrected for hemoglobin [Visit 1]): ≥30% to <80% predicted of normal performed within 52 weeks of Visit 1 (Screening).
  8. 08. FVC ≥45% predicted normal at Visit 1 (Screening) and Visit 2 (Day 1).
  9. 09. Male participants and female participants of childbearing potential (FOCBP; 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 participant) or the signing of the ICF (for the female participant), during the study, and until 90 days after the last dose of study drug. Participants agree not to donate eggs or sperm during the same period. Male participants must use a condom and female partners of male participants who are of childbearing potential must use a highly effective method of contraception. Highly effective contraception is defined below: a. A highly effective method of contraception is one that results in a low failure rate (i.e., <1% per year) when used consistently and correctly. Such methods of highly effective contraception include: i. sexual abstinence, defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the participant. ii. a vasectomized partner iii. bilateral tubal occlusion iv. any effective intrauterine device/hormone-releasing system, and progesteroneonly (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 highly effective methods and are not acceptable methods of contraception for this study. 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.
