Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Scarring of the lung, termed pulmonary fibrosis (PF), is a chronic, progressive, and usually fatal disorder. While two anti-fibrotic drugs have been approved for treating PF of unknown cause (idiopathic pulmonary fibrosis or IPF), neither drug is curative, and nearly 40% of patients stop taking the prescribed drug within a year because of side effects. The study includes the use of saracatinib, an investigational drug originally developed to treat certain types of cancers, in the treatment of IPF in a Phase 1b/2a clinical trial.

The objectives of this study are to: i) evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics, and to explore the efficacy of saracatinib in IPF; ii) identify biomarkers of Src kinase activity and fibrogenesis linked to pulmonary fibrosis; and iii) explore the application of these biomarkers to assess the anti-fibrotic effect of saracatinib in IPF patients

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a double blind, randomized, placebo-controlled, single-dose, four-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. In the second part of the trial, we will use a simple randomization scheme to achieve the 8:1 randomization across sites. 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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. IPF of any duration, confirmed or diagnosed by ILD center or expert according to Fleischner Guidelines (33). Subjects with a probable or indeterminant CT scan who otherwise meet the Fleischner criteria for IPF are eligible to be included in the study after a multidisciplinary evaluation. A positive Envisia genomic classifier score (34) on a lung biopsy specimen will be considered as strong evidence for a diagnosis of IPF. Subjects with a positive invisia genomic classifier score in conjunction with a probable or indeterminant CT scan are eligible to be included in the study after a multidisciplinary evaluation.
2. Women or men \>40 years of age at the time of screening
3. FVC%\>45% of predicted value (GLI-2012)
4. Single breath DLCO% ≥ 30 - inclusive of predicted (without bronchodilator and uncorrected for hemoglobin GLI-2017)
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 \[i.e., bilateral tubal ligation, bilateral oophorectomy or complete hysterectomy\] 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 (from 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.
