VANCOUVER, BC / ACCESS Newswire / April 7, 2026 / BioNxt Solutions Inc. ("BioNxt" or the "Company") (CSE:BNXT)(OTCQB:BNXTF)(FSE:BXT), a bioscience innovator specializing in advanced drug delivery systems, is pleased to announce the official registration of unitary effect for European Patent No. 4539857 covering the Company's proprietary sublingual cladribine oral thin film (ODF) platform.

The European Patent Office registered the patent's unitary effect on March 31, 2026, with effect from March 11, 2026. The Unitary Patent provides centralized protection across 18 participating European countries, including major pharmaceutical markets such as Germany, France, Italy, the Netherlands, Sweden, and Portugal.

Core Patent Covers Sublingual Cladribine Film Technology

The patent relates to a sublingual pharmaceutical composition containing cladribine, preferably formulated as a cladribine-cyclodextrin complex and embedded in a hydrophilic polymer-based oral thin film matrix.

The patent protected technology is designed for transmucosal delivery and is applicable to multiple sclerosis as well as additional autoimmune indications, including myasthenia gravis and neuromyelitis optica spectrum disorders.

With a priority date of June 15, 2022, the patent establishes long-term intellectual property protection for BioNxt's lead drug delivery platform.

Unitary Patent Unlocks Scalable European Commercialization

The Unitary Patent system allows BioNxt to secure and enforce patent protection across 18 EU member states under a single legal framework, significantly reducing administrative complexity compared to traditional national validation routes.

This milestone enhances BioNxt's ability to pursue regional licensing agreements, strategic co-development partnerships, and efficient market access across Europe, and represents a key step in the Company's transition toward commercialization of its lead product candidate, BNT23001 (sublingual cladribine ODF).

ODF Platform Demonstrates Strong Preclinical and Clinical Progress

BioNxt's ODF platform consists of a thin, fast-dissolving film administered sublingually, enabling drug absorption through the oral mucosa while bypassing the gastrointestinal tract. This approach is designed to improve bioavailability, reduce variability in drug absorption, and enhance patient compliance, particularly in populations with swallowing difficulties.

Preclinical studies supporting the cladribine ODF program have demonstrated comparable systemic exposure to the reference oral product Mavenclad^®, supporting bioequivalence potential and favorable tolerability with no treatment-related adverse effects observed following repeated sublingual administration.

BioNxt is also advancing a human bioavailability study comparing its ODF formulation with the marketed tablet, representing a key step toward regulatory approval.

Management Highlights Strategic Importance of European Patent

"The registration of unitary effect for EP4539857 marks an important milestone in our European IP strategy," said Hugh Rogers, CEO of BioNxt. "By securing protection across 18 key markets under a single framework, we are strengthening our foundation for commercialization and future partnership opportunities."
