Saracatinib in the Treatment of Idiopathic Pulmonary Fibrosis — STOP-IPF  

Idiopathic Pulmonary Fibrosis (IPF) Clinical Trial

Official title: Use of the Src Family Kinase Inhibitor Saracatinib in the Treatment of Idiopathic Pulmonary Fibrosis

Status Active, not recruiting

Clinical Trial Summary

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

Clinical Trial Description

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. ;
