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
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Idiopathic Pulmonary Fibrosis (IPF) | Drug: Saracatinab Drug: Placebo | Phase 1 Phase 2 |
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.

- Safety of saracatinib in IPF as measured by frequency of adverse events [ Time Frame: 24 weeks ]Safety data will be listed and summarized with patient counts and percentages in each treatment arm
- Tolerability of saracatinib in IPF as measured by Severity of adverse events [ Time Frame: 24 weeks ]A listing of all adverse events by patient will be presented. This listing will include patient number, adverse event (actual term and preferred term), event stand and end dates, CTCAE grade, relationship to the study drug/procedure, seriousness and outcome. A listing of SAEs will be produced using the similar format. This is not a scale. It is a data capture tool.
- Pharmacokinetics of saracatinib in IPF as measured by serum levels [ Time Frame: 24 weeks ]Serum levels of saracatinib
- Pharmacodynamics of saracatinib in IPF as measured by change in serum β-CTX [ Time Frame: 24 weeks ]Change in serum β-CTX as a Src kinase dependent biomarker
- Efficacy of saracatinib in IPF as measured by change in FVC [ Time Frame: 24 weeks ]Change in FVC from baseline
- Efficacy of saracatinib in IPF (HRCT) [ Time Frame: 24 weeks ]Change in HRCT quantitative analysis of the extent of pulmonary fibrosis. The analysis of HRCT data will involve data-driven texture analysis (DTA), a machine learning method capable of automatic detection and quantification of lung fibrosis on HRCT
- Efficacy of saracatinib in IPF (DLCO) as measured by change in DLCO [ Time Frame: 24 weeks ]Change in diffusing capacity of the lung for carbon monoxide (DLCO)
- Efficacy of saracatinib in IPF (exacerbations) as measured in time to first acute exacerbation [ Time Frame: 24 weeks ]Time to the first acute exacerbation
- Efficacy of saracatinib in quality of life in IPF (SGRQ) as measured by total score on SGRQ questionnaire [ Time Frame: 24 weeks ]Total score on the SGRQ questionnaire. St. George's Respiratory Questionnaire (SGRQ) is a 50-item, self-administered, respiratory-specific questionnaire with items covering three domains: symptoms, activities, impacts. Each domain and a total score range from 0-100, with higher scores connoting greater impairment.
- Efficacy of saracatinib in quality of life in IPF (L-IPF) as measured by total score on L-IPF questionnaire [ Time Frame: 24 weeks ]Total score on the L-IPF questionnaire. Living with IPF (L-IPF) is an IPF-specific questionnaire whose 43 items cover two modules: symptoms and impacts. A model-based scoring algorithm has been developed via psychometric methods.

- 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.
