BRIDGEWATER, N.J., April 19, 2023 (GLOBE NEWSWIRE) — VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”), a clinical-stage biopharmaceutical company developing proprietary, innovative and differentiated therapies for the treatment of immuno-inflammatory conditions, today announced new preclinical data showing the positive effect of its novel pan-BET inhibitor, VYN201, in a preclinical model of idiopathic pulmonary fibrosis (“IPF”).
“The data from this well-validated preclinical model of IPF clearly demonstrates VYN201’s potential to deliver a potent anti-inflammatory and anti-fibrotic response,” said David Domzalski, President and Chief Executive Officer of VYNE. “These data in IPF support our thesis that VYN201 has potential utility as a locally-administered therapy across a variety of immuno-inflammatory indications and further underscores the potential value of our InhiBETTM BET inhibitor platform.”
Bleomycin-Induced Mouse Model
IPF is a chronic, life-threatening, fibrosing lung disease with few treatment options. Patients experience debilitating symptoms, including shortness of breath and difficulty performing daily activities. The current standard of care treatment options for IPF have been shown to have only a modest impact on slowing the progression of the disease and have been associated with significant side effects.
In this well-validated preclinical model for IPF, lung fibrosis was induced in mice using a single intratracheal dose of bleomycin. Fibrosis was left to develop for seven days, and thoracic tomography images were obtained to stage fibrotic development. Animals were assigned to six treatment groups: untreated and unstimulated control, placebo, and one of four doses of VYN201 (0.1, 0.2, 0.5, and 1.0 mg/ml) (N=6/group). Each treatment group was dosed intratracheally every other day for 14 days. Changes in blood oxygen saturation, Ashcroft scoring (a standardized numerical scale used to quantify the extent of lung fibrosis in histological samples), lung hydroxyproline (a tissue biomarker for fibrosis), and volumetric lung function were assessed.
