Promedior Announces Presentation of Retrospective Quantitative Imaging Analysis of Phase 1b Data in Idiopathic Pulmonary Fibrosis
Promedior has announced that retrospective quantitative imaging data from the company’s Phase Ib clinical trial of PRM-151, for the treatment of idiopathic pulmonary fibrosis (IPF), was presented in a poster at the 18th International Colloquium on Lung and Airway Fibrosis (ICLAF), which is being held in Mont Tremblant, Quebec, Canada, 20–24 September 2014.
The data show that changes seen with structural and functional imaging of IPF patient’s lungs generally correlate with and appear complementary to pulmonary function tests. Both methods showed correlation with increases in Forced Vital Capacity (FVC) % predicted, normal lung, and lobar volumes in some subjects treated with PRM-151. In all placebo patients, decreases in both FVC % predicted and normal lung were observed, with decreased lobar volumes in some patients.
With a novel mechanism of action that is targeted to prevent and reverse fibrosis, PRM-151 has the potential to address the fundamental fibrotic pathology of IPF. Retrospective analyses of High Resolution CTs (HRCT) from the Phase Ib study assessed both volumetric quantification of interstitial lung abnormalities (ILA) and lobar volumes. The data support prospective use of these imaging techniques as biomarker endpoints to provide a more robust signal determination to support rapid development and require fewer patients in future clinical trials of PRM-151 in IPF.
The title of the poster presentation at ICLAF is 'Structural and Functional Quantitative Imaging Techniques are Complimentary in Retrospective Analysis of PRM-151 Data in Idiopathic Pulmonary Fibrosis (IPF)'
