Polyrizon (Nasdaq: PLRZ) has announced its clinical strategy for PL-14, an intranasal allergy blocker designed for seasonal allergic rhinitis. The company has structured a comprehensive clinical plan ahead of a pre-submission meeting with the FDA.
The clinical studies will evaluate three key aspects:
- Efficacy and safety under natural exposure during peak allergy season
- Human Factors study for usability and patient acceptance
- Assessment of nasal residence time of the PL-14 formulation
The biotech company plans to initiate clinical trials in the U.S. and Europe between late 2025 and early 2026, following preclinical work completion and FDA consultation.
Polyrizon (NASDAQ: PLRZ) has initiated preclinical studies for intranasal Benzodiazepines (BZDs) using its proprietary Trap and Target™ (T&T) platform for treating acute repetitive seizures and status epilepticus. The studies, conducted in collaboration with Professor Fabio Sonvico from the University of Parma, will evaluate drug loading capacity, release kinetics, nasal deposition, and stability.
The global acute repetitive seizures market, valued at $3.15 billion in 2024, is projected to grow at a 12.7% CAGR from 2025-2030. Additionally, the epilepsy treatment devices market is expected to reach $787.3 Million by 2033, growing at a 4.1% CAGR.
The initiative aims to develop a faster, safer, and more accessible solution for managing acute seizures outside clinical settings, targeting the approximately 50 million people worldwide affected by epilepsy according to WHO data.
Polyrizon (Nasdaq: PLRZ) has signed a non-binding Letter of Intent (LOI) with an unnamed biotech company focused on psychedelic-derived therapeutics to develop a novel intranasal formulation for psychedelic-based treatments. The collaboration will leverage Polyrizon's proprietary intranasal hydrogel platform to optimize drug delivery.
Under the LOI terms, Polyrizon will lead the formulation development using its mucoadhesive drug delivery technology, while the psychedelic company will fund research and development, including feasibility studies. Upon successful proof of concept, the parties plan to negotiate a definitive agreement covering IP ownership, commercialization rights, and financial terms, with Polyrizon receiving royalties on future product commercialization.
Polyrizon (Nasdaq: PLRZ) has initiated preclinical studies for intranasal Naloxone using their proprietary Trap and Target™ (T&T) platform.
