Insights

Polyrizon adds a targeted CNS drug-delivery collaboration without disclosed financial terms.

Polyrizon is partnering with Clearmind Medicine to develop an intranasal formulation of MEAI, a proprietary, non-hallucinogenic neuroplastogen aimed at addiction-related and other central nervous system conditions. The project leverages Polyrizon’s intranasal delivery platforms, including its hydrogel-based technologies.

The agreement is strategically aligned with Polyrizon’s focus on intranasal administration, a route often explored for CNS therapies due to potential advantages over oral delivery. However, the information provided does not quantify milestones, timelines, or economics, so the immediate financial impact remains unclear.

Given the pre-clinical stage of Polyrizon’s technology and Clearmind’s ongoing development programs, the collaboration mainly expands optionality for both parties. Future SEC reports and clinical updates from Clearmind will be needed to understand whether this formulation advances into later-stage trials.

Polyrizon Signs an Agreement to Develop Intranasal Proprietary Non-Hallucinogenic Neuroplastogen Formulation

 

Collaboration aims to leverage Polyrizon’s advanced proprietary intranasal delivery platform to support clinical development of Clearmind’s drug candidate proprietary MEAI

 

Raanana, Israel, Feb. 06, 2026 (GLOBE NEWSWIRE) -- Polyrizon Ltd. (Nasdaq: PLRZ) (“Polyrizon” or the “Company”), a pre-clinical-stage biotechnology company developing intranasal protective solutions, today announced that it has entered into a development agreement with Clearmind Medicine Inc. (Nasdaq: CMND) (“Clearmind”), a clinicalstage biopharmaceutical company focused on the discovery and development of novel neuroplastogen-derived therapeutics to solve major under-treated health problems. Under this agreement, Polyrizon will develop a proprietary intranasal formulation of MEAI (5methoxy2aminoindane), Clearmind’s proprietary, next-generation, non-hallucinogenic neuroplastogen drug candidate, intended for use in the treatment of addictionrelated and other centralnervoussystem (CNS) conditions.

 

The collaboration between companies holds both scientific and strategic rationale as the objective of the collaboration is to advance an intranasal MEAI formulation to support Clearmind’s future clinical development programs initiatives.

 

Polyrizon’s technology platforms are designed to enable:

 

Enhanced nasal residence time, through specialized gellike mechanisms

 

Consistent and targeted delivery of active compounds

 

Optimized patient usability

 

Formulation flexibility tailored to the physicochemical profile of the API

 

Intranasal administration is widely studied as a delivery route with potential advantages over oral administration for certain disorders (or indications), particularly those intended for CNS activity. Potential advantages, to MEAI, include:

 

Bypassing firstpass metabolism, which may allow more direct systemic access

 

Potentially faster absorption, depending on compound characteristics

 

Lowering effective dose

 

These factors collectively support the exploration of intranasal delivery for MEAI as Clearmind continues its development efforts.

 

Tomer Izraeli, Chief Executive Officer of Polyrizon, commented,: “We are proud to collaborate with Clearmind on the development of an intranasal formulation of MEAI. Our proprietary intranasal technology is designed to enable more targeted, efficient delivery, and we believe it may offer meaningful value as Clearmind advances MEAI through its clinical pathway. We believe that this agreement reflects Polyrizon’s growing role as a partner of choice for companies seeking specialized intranasal drugdelivery expertise.”

 

 

 

 

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.
