BIONXT REPORTS SUCCESSFUL FINAL IN-VIVO DOSING STUDY RESULTS SUPPORTING SUPERIOR BIOAVAILABILITY OF CLADRIBINE SUBLINGUAL ODF

Bionxt Solutions Inc. has completed and received preliminary results from its comparative pharmacokinetics (PK) large-mass animal study in pigs. The study measured how efficiently cladribine is absorbed into the bloodstream over time and compared Bionxt's proprietary orally dissolving film (ODF) with the reference tablet formulation, evaluating the company's swallow-free, sublingual ODF formulation for multiple sclerosis (MS).

Bionxt reports that the study outcome was successful and supports superior bioavailability for the company's cladribine ODF formulation under the study conditions. The company has initiated a full internal screening and assessment of the final data set, including calculations and interpretation of key pharmacokinetic parameters. Further information will be provided once Bionxt has completed its comprehensive internal analysis.

"We are extremely encouraged by the successful outcome of this study," said Hugh Rogers, chief executive officer at Bionxt. "The results reinforce our belief that sublingual ODF delivery can materially improve the efficiency of cladribine administration and may ultimately support better patient tolerability and adoption. We look forward to sharing additional details once our complete internal analysis is finalized. The data from this study is critical to optimize the dosing parameters in our upcoming human bioequivalence study."

Study overview: comparative pharmacokinetics study in pigs

To evaluate how effectively Bionxt's swallow-free cladribine ODF delivers cladribine into the bloodstream, the company conducted a comparative crossover pharmacokinetics study in adult pigs, weighing approximately 40 to 50 kilograms. This specific breed of pig is widely used in pharmaceutical research as a non-rodent large-mass preclinical model due to their high physiological, anatomical and metabolic similarities to humans, particularly in drug absorption and systemic exposure.

The objective was to compare Bionxt's cladribine 10-milligram orally dissolving film (ODF) with the reference name-brand 10 mg tablet, a commercially established multiple sclerosis therapy with annual global sales exceeding $1-billion (U.S.) and continued double-digit annual growth, with both formulations administered at a single dose equivalent to five mg of cladribine per animal. The reference tablet was administered by oral dosing via gavage, while the ODF was placed directly into the oral cavity to support sublingual absorption.

To track cladribine levels over time, blood samples were collected before dosing and at several time points over 24 hours following administration. This allowed Bionxt to measure key performance indicators such as peak concentration, overall exposure and how long cladribine remained in the body, supporting a clear assessment of bioavailability.

The study was initiated in November, 2025, and completed in December, 2025, with the final data set now received by the company for internal analysis.

Potential to reduce side effects and lower required active ingredient

The company's study results confirm that enhanced bioavailability achieved through sublingual ODF delivery materially improves delivery efficiency compared with conventional oral administration. By enabling more efficient absorption of cladribine into the bloodstream, the ODF approach supports the achievement of therapeutic exposure with lower overall systemic drug exposure, which is a critical factor in managing tolerability for immunomodulatory therapies such as cladribine.

This improved delivery efficiency directly supports Bionxt's strategy to reduce unnecessary systemic burden, creating the foundation for a meaningful reduction in dose-related side effects while maintaining pharmacokinetic performance. In addition, the swallow-free, sublingual ODF format offers a more patient-friendly treatment experience, particularly for patients with swallowing difficulties or sensitivity to conventional oral dosage forms.

Bionxt views these findings as a key validation of its ODF drug-delivery platform and a strategically important step in building a differentiated multiple sclerosis therapy profile with strong commercial and partnering potential.

Strategic significance: addressing a large and growing MS market

Multiple sclerosis represents a large global market, with approximately 2.3 million people living with MS worldwide and forecasts indicating the global MS drug market is expected to exceed $41-billion (U.S.) by 2033. Within this market, Mavenclad (cladribine tablets) is a well-established high-efficacy therapy with annual global sales exceeding $1-billion (U.S.) and sustained double-digit growth, although systemic oral therapy can require monitoring and may be associated with adverse effects that influence real-world adoption.

Cladribine also holds promise for the treatment of additional neurodegenerative diseases, such as myasthenia gravis (MG).

Patent position strengthened -- final granting expected shortly

Bionxt further confirms that patent protection for its cladribine ODF program has already been confirmed, with additional final (national level) patent grants expected shortly, strengthening the company's intellectual property position and supporting potential future licensing and partnering opportunities.

Next steps and upcoming updates

Bionxt has initiated internal screening and full evaluation of the study data set and expects to provide additional disclosure once final calculations, interpretation and internal validation are complete. The company intends to share further updates regarding next development milestones in due course.
