Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Adverse Events Occurring Over the Trial Period

    Number of participants with adverse events occurring over the trial period incl. number of participants with any TEAE, serious TEAEs, TEAEs leading to withdrawal from trial, TEAEs leading to discontinuation of treatment, treatment-related TEAEs leading to discontinuation of treatment, TEAEs leading to death, and serious treatment-related TEAEs. Adverse events were recorded from signing of informed consent until end of trial. Nature and frequency of adverse events are presented in details in the adverse events section.

    Trial period of 36 weeks

Secondary Outcomes (11)

  • Change From Baseline in Forced Vital Capacity (Non-imputed Data)

    12, 24, and 36 weeks

  • Change From Baseline in Forced Vital Capacity (Imputed Data)

    12, 24, and 36 weeks

  • Rate of Forced Vital Capacity Decline Over Time, FAS

    12, 24, and 36 weeks

  • Plasma Concentration of C21 Evaluated in a Sub-set of Subjects, Day 1

    Prior to dosing, 30 min post dose, 1 h post dose, 2 h post dose, 3 h post dose, and 4 h post dose on Day 1

  • Plasma Concentration of C21 Evaluated in a Sub-set of Subjects, Week 12

    Prior to dosing, 30 min post dose, 1 h post dose, 2 h post dose, 3 h post dose, and 4 h post dose at Week 12

  • +6 more secondary outcomes

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Written informed consent, consistent with ICH-GCP R2 and local laws, obtained before the initiation of any trial related procedure
  • A diagnosis of IPF within 5 years prior to Visit 1, as per either ATS/ERS/JRS/ATLAT/Fleischner guidelines
  • Age ≥40 years
  • Forced vital capacity (FVC) ≥60% predicted at Visit 1 (specifically for UK: FVC ≥80% predicted at Visit 1)
  • Forced expiratory volume in the first sec (FEV1)/FVC ratio ≥0.7 prebronchodilator at Visit 1
  • Oxygen saturation (SpO2) \>85% by pulse oximetry while breathing ambient air at rest at Visit 1
  • High-resolution computed tomography (HRCT) within 36 months prior to Visit 1 with central reading demonstrating either a or b, and c:
  • a. A pattern consistent with usual interstitial pneumonitis (UIP) according to ATS/ERS/JRS/ALAT or Fleischner guidelines i. UIP ii. Probable UIP or b. A pattern indeterminate for UIP according to either ATS/ERS/JRS/ALAT or Fleischner guidelines and a historical biopsy consistent with IPF c. Extent of fibrosis \> extent of emphysema
  • Fully vaccinated against COVID-19 prior to screening (Visit 1). Subjects are considered fully vaccinated for COVID-19 ≥14 days after they have received vaccination dose(s) according to local label

You may not qualify if:

  • Previous use of antifibrotic treatment for an interstitial lung disease (e.g. nintedanib or pirfenidone) for \> 6 months
  • Smoking (including e-cigarettes) within 6 months prior to Visit 1
  • Body mass index (BMI) \>35 or \<18
  • IPF exacerbation within 3 months prior to Visit 1:
  • Acute worsening or development of dyspnoea 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 (if no previous computed tomography is available, the qualifier "new" can be dropped)
  • Deterioration not fully explained by cardiac failure or fluid overload
  • Concurrent serious medical condition with special attention to cardiac or ophthalmic conditions (e.g. contraindications to cataract surgery) which in the opinion of the investigator makes the subject inappropriate for this trial
  • Malignancy within the past 5 years with the exception of in situ removal of basal cell carcinoma and cervical intraepithelial neoplasia grade I
  • Treatment with any of the medications listed below within 4 weeks prior to Visit 1:
  • Cytochrome p450 (CYP) 3A4 inducers (e.g. rifampicin, phenytoin, St. John's Wort)
  • CYP3A4 inhibitors (e.g. clarithromycin, ketoconazole, nefazodone, itraconazole, ritonavir)
  • Medicines that are substrates of CYP1A2, CYP3A4 or CYP2C9 with a narrow therapeutic range
  • Experimental drugs
  • Any systemic immunosuppressive therapies other than:
  • +21 more criteria
