Polyrizon announced results from its biocompatibility evaluation program for its proprietary Nasarix Allergy Blocker nasal spray, with all required biological safety tests meeting their predetermined acceptance criteria. The evaluation program was designed in accordance with internationally recognized standards for biological safety assessment of medical devices, including the ISO 10993 series, FDA guidance, and applicable European regulatory requirements. The program was developed to assess the safety and biocompatibility profile of Nasarix, a drug-free mucoadhesive nasal spray intended to help reduce exposure to airborne allergens associated with seasonal allergic rhinitis. The completed testing program evaluated key biological safety endpoints identified for the device, including: cytotoxicity; sensitization; irritation / intracutaneous reactivity materialmediated pyrogenicity and acute systemic toxicity. In addition, long-term systemic toxicity was assessed through a toxicological risk assessment conducted in accordance with ISO 10993-17, demonstrating substantial safety margins across the product's constituent materials under intended conditions of use. The biocompatibility evaluation was based on the final Nasarix product configuration and supported by toxicological assessments of the formulation components, manufacturing processes, packaging materials, and intended patient exposure. According to the biological evaluation plan, the product consists of well-characterized materials with established safety profiles and utilizes a manufacturing process designed to minimize biological risk.
