Insights
Polyrizon's entry into the epilepsy rescue treatment space represents a pipeline expansion with both opportunity and significant development challenges ahead. The company is targeting the
This announcement marks only the initial preclinical stage of development - they're studying basic parameters like drug loading capacity and release kinetics using a model molecule, not even the actual benzodiazepine compounds yet. The full development pathway would require animal studies, IND filing, and multiple clinical trials before potential commercialization.
Investors should recognize that several intranasal benzodiazepine products already exist in this space, including UCB's Nayzilam (midazolam) and Neurelis's Valtoco (diazepam), both FDA-approved for seizure rescue. For Polyrizon to capture market share, their proprietary Trap and Target™ platform would need to demonstrate superior drug delivery characteristics or patient benefits.
The collaboration with Professor Sonvico adds credibility to their technical approach, but the company's financial resources (
Polyrizon's exploration of intranasal benzodiazepine delivery represents an application of their Trap and Target™ platform to a well-established clinical need. The intranasal route offers significant advantages for seizure rescue: it bypasses first-pass metabolism, enables rapid brain delivery through the olfactory pathway, and allows for administration by non-medical personnel in emergency situations.
The preclinical study will assess critical technical parameters that determine commercial viability: drug loading capacity (how much active ingredient the gel can hold), release kinetics (how quickly the drug is delivered to the nasal mucosa), and stability (shelf-life in various conditions). These factors will determine whether their formulation can deliver therapeutic levels rapidly enough for seizure interruption.
The use of a model molecule at this stage is standard practice but means they're still years away from clinical testing. Intranasal benzodiazepine delivery presents specific challenges including nasal cavity volume, mucociliary clearance, and ensuring consistent absorption across patient populations.
The current market includes several FDA-approved intranasal seizure rescue options, so Polyrizon will need to demonstrate either improved efficacy, faster onset, greater reliability, or enhanced usability to differentiate their product. Their hydrogel approach could potentially offer advantages in terms of increased residence time in the nasal cavity or more precise dosing, but this remains to be proven in clinical studies.
Raanana, Israel, March 25, 2025 (GLOBE NEWSWIRE) -- Polyrizon Ltd. (Nasdaq: PLRZ) (the "Company" or "Polyrizon"), a development stage biotech company specializing in the development of innovative intranasal hydrogels, announced today 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
According to the latest research study, the global epilepsy treatment devices market was valued at approximately USD 526.8 Million in 2023 and is expected to reach a value of around USD 787.3 Million by 2033, growing at a compound annual growth rate (CAGR) of about
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. The studies will assess key parameters, such as drug loading capacity, release kinetics, nasal deposition and stability using a model molecule, that simulates the behavior of intranasal benzodiazepines at this early stage,laying the groundwork for further safety and efficacy testing in preclinical and clinical studies.
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.
