Pieris Pharmaceuticals Announces Dosing of First Subject in Phase 1 Trial of Inhaled CTGF Inhibitor PRS-220
BOSTON, MA / ACCESSWIRE / November 1, 2022 / Pieris Pharmaceuticals, Inc. (NASDAQ:PIRS), a clinical-stage biotechnology company advancing novel biotherapeutics through its proprietary Anticalin® technology platform for respiratory diseases, cancer, and other indications, today announced that the first subject has been dosed in the phase 1 study of PRS-220, an oral inhaled Anticalin protein targeting connective tissue growth factor (CTGF) for the treatment of idiopathic pulmonary fibrosis (IPF) and other forms of fibrotic lung disease. The phase 1 dose escalation study will evaluate the safety, tolerability, and pharmacokinetics of PRS-220 in heathy volunteers.
IPF affects over three million patients worldwide and approximately 130,000 patients in the United States. Median survival is three to five years from the time of diagnosis, with standard of care conferring only modest benefit. CTGF, a protein localized in the extracellular matrix, is a driver of fibrotic tissue remodeling as a consequence of an aberrant wound healing process. Over-expression of this target in lung tissue is observed in patients suffering from IPF, and clinical data indicate inhibition of CTGF reduces the decline in lung function among these patients. Direct administration of PRS-220 to the lung via inhalation should achieve high local concentrations, and hence a more effective inhibition of CTGF than systemically administered interventions.
"The initiation of this trial is an important step in the development of PRS-220, a fully proprietary program that we believe has the potential to offer a meaningful improvement in the quality of life for patients suffering from this rare and, ultimately, terminal disease," said Stephen S. Yoder, President and CEO of Pieris. "PRS-220 is the second inhaled respiratory program we have brought into the clinic, and we look forward to reporting the results from this study next year."
