Polyrizon Targets $3.15B Epilepsy Market with Preclinical Studies for Innovative Rescue Treatment

Raanana, Israel, May 13, 2025 (GLOBE NEWSWIRE) -- Polyrizon Ltd. (Nasdaq: PLRZ) (the “Company” or “Polyrizon”), a development stage biotech company specializing in the development of innovative intranasal hydrogels, recently announced the initiation of preclinical studies for intranasal Benzodiazepines (BZDs), a first-line treatment for acute repetitive seizures (ARS) and status epilepticus, using its proprietary drug delivery platform.

According to the World Health Organization (WHO), epilepsy is a neurological condition affecting about 50 million people worldwide. Many existing therapies fail to provide adequate control of acute repetitive seizures and may come with undesirable adverse effects.  The global acute repetitive seizures market size was estimated at USD 3.15 billion in 2024 and is projected to grow at a CAGR of 12.7% from 2025 to 2030.

The study will be conducted in collaboration with Professor Fabio Sonvico, Associate Professor at the Department of Food and Drug of the University of Parma (Italy) a leading expert in the development of intranasal and pulmonary drug delivery solutions and a member of the Company’s Scientific Advisory Board.

These preclinical studies mark a step forward in evaluating Polyrizon’s Trap and Target™ (T&T) platform for the intranasal administration of Benzodiazepine, designed to enable rapid, targeted, and patient-friendly seizure rescue therapy.

BZDs are well-established, first-line drugs for the acute treatment of seizures. They act by enhancing the inhibitory effects of gamma-aminobutyric acid (GABA) at the GABA-A receptor in the central nervous system, helping to quickly suppress seizure activity.

Intranasal delivery of BZDs offers multiple advantages over traditional routes of administration, including ease of use and increased accessibility. This approach allows emergency responders, caregivers and at-risk individuals to administer life-saving medication rapidly and independently in out-of-hospital settings.

“Launching this preclinical program marks an important milestone in our initiative to improve emergency treatment options for epilepsy patients,” said Tomer Izraeli, CEO of Polyrizon. “We believe our intranasal delivery platform has the potential to offer a faster, safer and more accessible solution for managing acute seizures outside of clinical settings.”

About Polyrizon

Polyrizon is a development stage biotech company specializing in the development of innovative medical device hydrogels delivered in the form of nasal sprays, which form a thin hydrogel-based shield containment barrier in the nasal cavity that can provide a barrier against viruses and allergens from contacting the nasal epithelial tissue. Polyrizon’s proprietary Capture and Contain ^TM, or C&C, hydrogel technology, comprised of a mixture of naturally occurring building blocks, is delivered in the form of nasal sprays, and potentially functions as a “biological mask” with a thin shield containment barrier in the nasal cavity. Polyrizon are further developing certain aspects of our C&C hydrogel technology such as the bioadhesion and prolonged retention at the nasal deposition site for intranasal delivery of drugs. Polyrizon refers to its additional technology, which is in an earlier stage of pre-clinical development, that is focused on nasal delivery of active pharmaceutical ingredients, or APIs, as Trap and Target ™, or T&T.
