• - 79 inclusive of predicted (without bronchodilator and uncorrected for hemoglobin) 5.

FEV1/FVC>70 (GLI-2012) 6. Provision of signed/dated written informed consent prior to any study-specific procedures. 7. Females must be of nonchildbearing potential (defined as surgically sterilized [ie, bilateral tubal ligation, bilateral oophorectomy or complete hysterectomy] or postmenopausal [defined as 12 months with no menses without an alternative medical cause] with a follicle-stimulating hormone [FSH] > 25.8 IU/L) or use a highly effective method of contraception (defined as combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation; progestogen only hormonal contraception associated with inhibition of ovulation; intrauterine device (IUD); intrauterine hormone-releasing system (IUS) for the duration of the study (from the time they sign consent) and for 3 months after the last dose of drug/matching placebo. 8. Male subjects must be surgically sterile or using an acceptable method of contraception (defined as barrier methods in conjunction with spermicides) for the duration of the study (fr om the time they sign consent) and for 3 months after the last dose of drug/matching placebo to prevent pregnancy in a partner. Male subjects must not donate or bank sperm for the duration of the study (from the time they sign consent) and for 3 months after the last dose of drug/matching placebo.

Exclusion Criteria:

1. Requirement for supplemental oxygen > 4 L/min at rest to maintain saturation > 90% 2. Active infection at screening or randomization. 3. Known active or latent hepatitis B or C. 4. Life expectancy for disease other than IPF < 2.5 years (Investigator assessment) 5. Listed for lung transplantation. 6. Taking pirfenidone or nintedanib in the last 4 weeks. 7. Pregnancy or lactation. 8. Known allergic reactions to components of saracatinib. 9. Treatment with another investigational drug or other intervention within 8 weeks. 10. Current smoker or tobacco use within 4 months. 11. Major surgery within the past 2 months. 12. Advanced hematologic, renal, hepatic, any lung disease determined by the investigator to be non-IPF related or metabolic disease that, in the opinion of the investigator, would make it unsafe for the person to receive study drug. 13. Previous lung transplantation. 14. Inability to attend scheduled study visits. 15. Inability to give informed consent. 16. Inability to perform pulmonary function testing. 17. History of malignancy in the past two years, other than squamous or basal cell skin cancer. 18. Previous acute exacerbation of IPF requiring hospitalization and/or antibiotics within 90 days before the first dose of the investigational product. 19. Liver function test results ≥3× upper limit of normal (ULN) liver isoform of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transpeptidase (GGT), or alkaline phosphatase (ALP) or ≥2×ULN total bilirubin (excepting documentation of benign hereditary cause). An isolated total bilibrubin elevation (ie, no significant concomitant elevation in ALT or AST) at baseline of ≤ 2xULN is permitted. If there is concomitant elevation in ALT or AST to ≤3xULN, then the threshold for total bilirubrin is ≤1.5xULN. 20. Creatinine clearance <30 mL/min calculated by Cockcroft-Gault formula. 21. Known pulmonary hypertension (PH) requiring PH-specific treatment. 22. Chronic oral corticosteroids at doses greater than prednisone 10 mg/day (or equivalent) 23.

This is a double blind, randomized, placebo-controlled, single-dose, three-site trial. The trial is a biomarker-based, integrated Phase 1b/2a clinical trial involving 100 subjects. One group (n=50) will receive placebo, while the other group (n=50) will receive 125 mg of oral saracatinib once daily. Randomization will be stratified by center. The randomization scheme will be in random blocks of 2 and 4 within each stratum to maintain balance. The study is designed to have interim analysis of the drop-out rates when approximately 30% of the randomized patients have achieved the 24-week assessment. Should the drop-out rate be higher than the 20% that is anticipated, a new sample size calculation will be performed to make sure that the power of the study is maintained at 80% . Duration of follow-up will be 28 weeks including 24 weeks of treatment with saracatinib or placebo.
