Polyrizon Ltd. (NASDAQ: PLRZ) shares began Wednesday higher. The Israeli-based firm, a development-stage biotech company specializing in the development of innovative intranasal hydrogels, today announced that the European Patent Office (EPO) has completed the technical preparations for the publication of the Company's European patent application entitled “Mucoadhesive Polymers for Nasal Drug Delivery.” The application was published under European publication number EP 4751737. The patent application covers Polyrizon’s proprietary Trap & Target™ (T&T) mucoadhesive polymer technology platform for nasal drug delivery. The technology is designed to enhance the interaction between pharmaceutical formulations and the nasal mucosa, potentially increasing formulation retention, improving drug absorption, and enabling more efficient delivery of active pharmaceutical ingredients through the nasal route.
Nasal drug delivery has emerged as an increasingly attractive administration route for a wide range of therapeutic compounds, offering rapid onset of action, non-invasive administration, and the potential to bypass gastrointestinal degradation and first-pass metabolism. Polyrizon’s technology is intended to address one of the key challenges of nasal administration, limited residence time within the nasal cavity, through the development of advanced mucoadhesive polymer systems.
The publication of the patent application represents a significant milestone in the Company's strategy to strengthen its intellectual property portfolio supporting future pharmaceutical applications and collaborations in the nasal drug delivery field.
PLRZ shares flew 23 cents, or 2%, to $11.68.
