Who can take part

You may be able to join if

  • 2. Diagnosed of IPF within 7 years prior to V1, as per applicable ATS/ERS/JRS/ALAT at the time of diagnosis.
  • 3. HRCT scan within 36 months prior to V1 with central reading confirming either a or b, and c: a. A pattern consistent with usual interstitial pneumonia (UIP) according to ATS/ERS/JRS/ALAT 2022 guideline: UIP or probable UIP. b. A pattern indeterminate for UIP according to ATS/ERS/JRS/ALAT 2022 guideline and a historical biopsy (surgical lung biopsy or transbronchial lung cryobiopsy) consistent with IPF. c. Extent of fibrosis > extent of emphysema.
  • 4. FVC ≥50% predicted at V1.
  • 5. DLCO (corrected for hemoglobin) ≥30% predicted at V1
  • 6. Either: a. On a stable dose of licensed IPF therapy for at least 8 weeks prior to V1 and expected to remain on this background treatment after randomization. Due to the risk of DDIs, concomitant treatment with pirfenidone is not allowed in this trial. b. Not currently receiving treatment for IPF with a licensed therapy for any reason, including prior intolerance, non-responsiveness, ineligibility, lack of access or voluntarily decline. Any such previous treatment must have been discontinued >8 weeks prior to V1.

You likely can't join if

  • 1. Concurrent serious medical condition which in the opinion of the investigator constitutes a risk or a contraindication for the participation in the trial or that could interfere with the trial objectives, conduct or evaluation, including active or suspected malignancy or history of malignancy within 5 years prior to V1, except appropriately treated basal cell carcinoma of the skin, fully resected and cured squamous cell carcinoma of the skin, “under surveillance” prostate cancer or in situ carcinoma of uterine cervix.
  • 18. Inability to refrain from smoking (including e-cigarettes and cannabis) on days of site visits until completion of trial procedures.
  • 19. Where applicable per country regulation, the participant must not currently be committed to an institution by virtue of an order issued either by judicial or administrative authorities.
  • 2. Airways obstruction with a pre-bronchodilator forced expiratory volume in one second (FEV1)/FVC ratio <0.7 at V1.
  • 20. The investigator considers the participant unlikely to comply with trial procedures, restrictions and requirements.
  • 3. Lower respiratory tract infection requiring antibiotics and not fully recovered according to investigator judgement within 4 weeks prior to V2.

  • 7. Anticipated life expectancy of at least 12 months at V1 and not anticipated to require a lung transplant during the trial period (being on a transplant list does not exclude a participant from the trial).
  • 8. Contraceptive use by women of childbearing potential (WOCBP) which is highly effective and consistent with local regulations regarding the methods of contraception for those participating in clinical trials. Male participants, if heterosexually active with a female partner of childbearing potential, or a pregnant or breastfeeding partner, must agree to use barrier contraception (male condom) and abstain from sperm donation for the duration of the treatment period and for at least 2 weeks after the last dose of the study drug.
  • 9. Written informed consent, consistent with ICH-GCP and local laws, obtained before the initiation of any trial-related procedure.
What rules you out
  • 1. Concurrent serious medical condition which in the opinion of the investigator constitutes a risk or a contraindication for the participation in the trial or that could interfere with the trial objectives, conduct or evaluation, including active or suspected malignancy or history of malignancy within 5 years prior to V1, except appropriately treated basal cell carcinoma of the skin, fully resected and cured squamous cell carcinoma of the skin, “under surveillance” prostate cancer or in situ carcinoma of uterine cervix.

Computed tomography with new bilateral ground-glass opacity and/or consolidation superimposed on a background pattern consistent with usual interstitial pneumonia pattern (if no previous computed tomography is available, the qualifier "new" can be dropped). c. Deterioration not fully explained by cardiac failure or fluid overload.
  • 12. Inability to generate a spirometry test at V1 meeting the standards of the ATS/ERS 2019 guideline.
  • 13. Treatment with pirfenidone (substrate of CYP1A2) within 8 weeks prior to V1 or anticipated need for pirfenidone during the participation in the trial.
  • 14. Treatment with the specific medications listed as per protocol within 2 weeks prior to V2 or anticipated need for such medication during the participation in this trial.
