Inclusion criteria

Inclusion criteria: 1. Participants, aged 40 years or older. 2. Diagnosis of IPF for up to 5 years prior to screening based on on American Thoracic Society (ATS)/ European Respiratory Society (ERS)/ Japanese Respiratory Society (JRS)/ Latin American Respiratory Society (ALAT) 2018 guidelines (Raghu et al, 2018). Note: If IPF diagnosis is within >3 to =5 years at screening, the participant must have evidence of progression within the last 24 months, as defined by decline in FVC percent predicted based on a relative decline of = 5%. 3. FVC percent of predicted =45%; historical FVC for entry in the study is permitted if within 1 month of screening. 4. Diffusing capacity for carbon monoxide (DLco) (hemoglobin-adjusted) =30%%; historical DLco for entry in the study is permitted if within 1 month of screening. 5. Participants currently receiving treatment for IPF with nintedanib or pirfenidone are allowed, provided these drugs have been given at a stable dose for at least 3 months before the Screening Visit and are expected to remain unchanged during the study stable dose is defined as the highest dose tolerated by the participant during = 3 months). 6. Estimated glomerular filtration rate = 50 mL/min, according to the Cockcroft-Gault equation. 7. Female participants of non-childbearing potential must be surgically sterile or post-menopausal. 8. Female participants of childbearing potential must use a contraceptive method with a failure rate of =65 years) no F.1.3.1 Number of subjects for this age range

Exclusion criteria

Exclusion criteria: 1. Receiving any non-approved agent intended for treatment of fibrosis in IPF. 2. Forced expiratory volume during the first second (FEV1) over the forced vital capacity (FVC) ratio (FEV1/FVC ratio) 450 msec for males or > 460 msec for females at the Screening visit (including Day -1) or prior to administration of the initial dose of study drug. 14. Any of the following liver function test criteria above specified limits: total bilirubin >1.5× the upper limit of normal (ULN); aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >3× ULN; alkaline phosphatase >2.5× ULN. Note: participants currently receiving nintedanib or pirfenidone as IPF SoC treatment, who have previously presented any liver function test elevations associated with nintedanib or pirfenidone treatment greater than that described above or resulting in dose reduction, treatment interruption, or discontinuation are not eligible. 15. Any of the following at Screening: hemoglobin <10.0 g/dL, or neutrophils <1500 /mm3, or platelets <100.000 /mL. 16. Pregnant or lactating females. 17. Daily use of phosphodiesterase-5 (PDE-5) inhibitor drugs (e.g., sildenafil, tadalafil, other) (Note: Intermittent use for erectile dysfunction is allowed). 18. A medical or surgical condition known to affect drug absorption (e.g., major gastric surgery). 19. Surgical procedures planned to occur during the study period. 20. Uncontrolled systemic arterial hypertension. 21. Has participated in a clinical trial with an investigational agent in the 30 days pri

Design outcomes

Primary

MeasureTime frame
Main Objective: Assessment of the safety and tolerability of PLN-74809;Secondary Objective: Assessment of pharmacokinetics (PK) of PLN-74809;Primary end point(s): Primary Safety Endpoint Nature and proportion of AEs between PLN-74809 and placebo groups (descriptive) Safety data from all participants who received at least one dose of study drug will be incorporated into the final safety analysis. Further details of the safety analyses will be provided in the SAP. AEs will be collected from the time the participant signs the ICF until the last study visit. Treatment-emergent adverse events (TEAEs) are defined as AEs that emerged or worsened in severity after the first administration of study drug;Timepoint(s) of evaluation of this end point: AEs will be collected from the time the participant signs the ICF until the last study visit.

Secondary

MeasureTime frame
Secondary end point(s): a. Secondary Pharmacokinetic Endpoints Plasma PLN-74809 concentrations at each sampling time point will be presented in listings and descriptive summary statistics by dose and visit. The data will also be presented graphically. Further details of the analyses will be provided in the SAP to be prepared and agreed prior to final ‘database lock’ at the end of the study. The PK analysis plan and report may be prepared separately from the SAP as appropriate. b. Secondary Pharmacodynamic Endpoints Saliva, urine, plasma and serum samples will be analyzed for biomarkers (presence or actual concentration). These samples will be used to determine the levels of these markers in participants and the relationship between these markers. Results will be presented by listings, descriptive summary statistics and in graphical form by treatment and dose and expressed as the relative change (and or absolute) for each participant.

In addition, relationships between PK and PD may be evaluated in an exploratory fashion and presented in graphical manner.;Timepoint(s) of evaluation of this end point: Day 1, Week 4, Week 12 and Week 14
