Polyrizon Announces GMP Manufacturing of Clinical Trial Material (CTM) with Eurofins CDMO AmatsiAquitaine S.A.S for Planned U.S. Clinical Study

Raanana, Israel, March 10, 2026 (GLOBE NEWSWIRE) -- Polyrizon Ltd. (Nasdaq: PLRZ) (“Polyrizon” or the “Company”), a pre-clinical-stage biotechnology company developing intranasal administrated solutions, today announced the successful production of a Good Manufacturing Practice (GMP) batch of clinical trial material (CTM) for its lead product candidate.

This milestone follows the Company’s previously announced manufacturing agreement with Eurofins CDMO AmatsiAquitaine S.A.S, a leading global GMP CDMO, established to support the supply of clinical trial material for Polyrizon’s clinical development program.

The GMP manufacturing milestone represents a key step in Polyrizon’s clinical development program and supports the company’s preparations for a planned clinical study in the United States later this year.

The GMP batch was manufactured following the successful production of two prior development batches, which demonstrated batch-to-batch consistency and product stability over time, supporting the robustness and reproducibility of the manufacturing process.

The CTM batch was produced in compliance with applicable GMP standards in collaboration with Eurofins CDMO AmatsiAquitaine S.A.S, and will be used to support upcoming clinical activities and regulatory submissions related to the study.

“This manufacturing milestone represents an important step in advancing our clinical development strategy,” said Tomer Izraeli, CEO of Polyrizon. “Following the successful production of development batches that confirmed manufacturing consistency and stability, the GMP production of clinical material enables us to move forward with our planned U.S. clinical study and reflects our continued commitment to developing innovative intranasal solutions designed to protect against airborne allergens and viruses.”

This milestone reflects Polyrizon’s continued progress toward advancing its intranasal technology platform and bringing novel preventive solutions for respiratory conditions closer to patients.

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.
