Polyrizon Ltd. (Nasdaq: PLRZ) has announced promising preclinical results for its PL-14 Allergy Blocker, as part of its Capture & Contain (C&C) platform. Conducted in collaboration with the University of Parma, the study demonstrated targeted deposition in the nasal vestibule, a critical site for early allergen contact. The PL-14 formulation exhibited over 60% deposition in this region, supporting its potential as a preventive treatment for allergic rhinitis. The study, led by Professor Fabio Sonvico, utilized a validated silicone-based human nasal cast to assess the spray deposition profile. Polyrizon plans to continue preclinical efforts and move towards clinical trials. The global allergen blocker market is projected to grow, with an expected value increase from USD 0.14 billion in 2024 to USD 0.21 billion by 2033.
