Polyrizon Announces Successful Completion of Key Manufacturing Upscaling Milestone for Its Nasal Spray Platform
Rhea-AI Summary
Polyrizon (Nasdaq: PLRZ) announced the successful completion of a key manufacturing upscaling milestone for its intranasal C&C platform on Dec 2, 2025. The company and its CDMO transitioned PL-14 from small-batch lab production to a larger-scale controlled run that validated key formulation parameters and showed the PL-14 formulation can be reliably produced at increased batch volumes while maintaining quality.
The batch is intended to support clinical trial material (CTM) for a clinical trial expected to commence in 2026 and is described as produced in line with U.S. and European regulatory standards, advancing readiness for clinical and regulatory activities and potential future commercial manufacturing.
Positive

- Manufacturing aligned with U.S. and European regulatory standards
Negative
- Clinical trial not yet initiated; CTM production planned only to support a 2026 start
- Upscaled run validates larger batches but does not confirm full commercial-scale production

Recent PLRZ news has been mostly positive, yet price reactions have alternated between sharp spikes and selloffs, with good news sometimes followed by negative returns.
This announcement continues a series of PLRZ milestones. On Nov 6, 2025, the company reported positive in‑vitro data for PL‑16 Viral Blocker, which saw a -5.31% move. On Dec 2, 2025, the same manufacturing upscaling milestone drove a 131.96% jump. Additional manufacturing and preclinical updates on Dec 3–4, 2025 produced mixed reactions, including a 104.02% gain and a -3.27% decline. An FDA pre‑submission meeting on Dec 8, 2025 then coincided with a -15.65% drop.
Regulatory & Risk Context
Polyrizon has an active Form F-3 shelf filed on 2025-11-07 to offer up to $50,000,000 of ordinary shares, warrants, and units. The shelf is not yet effective and has 0 recorded usages, but once effective it would allow flexible capital raises that could affect existing shareholders through future securities offerings.
Market Pulse Summary
The stock surged +132.0% in the session following this news. A strong positive reaction aligns with prior spikes around PLRZ manufacturing milestones, such as the 131.96% move on Dec 2, 2025. However, history also shows subsequent negative days after good news, highlighting volatility. With an effective manufacturing run and an unused $50,000,000 shelf in place, investors have balanced opportunities and dilution risk if future capital raises occur.

Ra’anana, Israel, Dec. 02, 2025 (GLOBE NEWSWIRE) -- Polyrizon Ltd. (Nasdaq: PLRZ) (“Polyrizon” or the “Company”), a biotechnology company developing intranasal products based on its proprietary Capture & Contain (C&C) platform, today announced the successful completion of a major manufacturing upscaling milestone for its proprietary nasal-spray product platform. This achievement marks a critical step toward supporting upcoming clinical and regulatory activities, as well as potential commercial readiness in the future.
During the upscaling process, Polyrizon and its manufacturing partner successfully transitioned from small-batch laboratory production to a larger-scale, controlled manufacturing run designed to validate key parameters of PL-14 formulation. The milestone demonstrates that the PL-14 formulation can be reliably produced at increased batch volumes while maintaining high-quality specifications. The manufacturing process is set to support the clinical trial material (CTM) needed for Polyrizon's clinical trial, which is expected to commence in 2026, offering high-quality and compliant production in line with USA and European regulatory standards.
"This successful batch production is a testament to the strength of our C&C technology and the expertise of our CDMO partner," said Tomer Izraeli, CEO of Polyrizon. "The process validated our manufacturing strategy. With this batch in hand, we are energized and prepared to advance into next batches towards clinical trial material manufacturing, which we believe brings us one step closer to addressing the unmet needs in the nasal spray market."
PL-14 is Polyrizon’s innovative intranasal protective spray designed to create a fast-acting, moisturizing barrier inside the nasal cavity, helping to trap, isolate, and neutralize airborne allergens before they reach the mucosa. Based on a proprietary bio-adhesive formulation developed by Polyrizon’s R&D team, PL-14 is engineered to provide extended protection, and offers a non-pharmacological solution for allergy sufferers in environments with high allergen exposure.
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.
