HYL Hyloris Pharmaceuticals SA

• Territorial expansion for a product candidate previously exclusively targeting the U.S.
• Kye Pharmaceuticals to register and commercialize in Canada

Liège, Belgium – 24 October 2023 – 7AM CET – Non-regulated information - Hyloris Pharmaceuticals SA (Euronext Brussels: HYL), a specialty biopharma company committed to addressing unmet medical needs through reinventing existing medications, today announces it has out-licensed its product candidate atomoxetine oral liquid for the treatment of attention deficit hyperactivity disorder (ADHD) in Canada to Kye Pharmaceuticals.

ADHD is one of the most common neurobehavioral disorders, affecting 4-6% of adults and 5-7% of children in Canada, or approximately 1,8 million Canadians1. It is a chronic condition for most patients, with approximately 60 to 80% of the symptoms of ADHD persisting into adulthood2.

Global prevalence of ADHD has increased significantly in recent years3, leading to an increased usage of ADHD therapies such as the well-established medication atomoxetine. In 2022, the Canadian market amounted to 17 million capsules (CAGR of 7,4% in the period 2020-2022)4 of atomoxetine.

Atomoxetine is currently not available as an oral liquid formulation in Canada. Considering the added value, significant market share penetration was often observed in countries when an oral liquid became available in this drug category5.

Kye Pharmaceuticals is targeting a regulatory submission in 2024, and will be the exclusive partner for commercialization in Canada. The territorial expansion for atomoxetine oral liquid should not result in additional product-related investments for Hyloris.

Stijn Van Rompay, Chief Executive Officer of Hyloris, commented: “We are proudly partnering with this local champion focused on commercializing therapies within pediatrics and neurosciences. Partnering atomoxetine oral liquid outside of the U.S. underlines our capability to bring innovative treatments to patients on a global scale, and unlock the hidden value in our existing pipeline of reformulated and repurposed product candidates.”

John McKendry, President of Kye, commented: “Many Canadians with ADHD are unable to take solid tablets as prescribed, and alternative formulations which have been available internationally are not readily available in the Canadian market. This partnership expands our growing portfolio of innovative ADHD treatments and will ensure Canadian patients have access to a liquid formulation of atomoxetine, a well-established non-stimulant medication.”

Under the terms of the agreement, Hyloris will be eligible to receive attractive sales-related milestone payments (totalling up to USD 7,5 million), and a substantial share of the revenue generated in Canada.

About Attention Deficit Hyperactivity Disorder (ADHD)

ADHD is a chronic mental childhood-onset disorder characterized by developmentally inappropriate and impaired inattention, motor hyperactivity, and impulsivity, with difficulties often continuing into adulthood. Children and adolescents suffering from ADHD experience challenging key formative years. Because of impulsive behaviour and slower rates of processing information, they perform poorly on standardized tests, score lower grades and are more likely to drop out of school.

About Atomoxetine oral liquid

Atomoxetine is a non-stimulant prescription medication used to treat ADHD symptoms in adults and children over the age of 6. For patients up to 70kg body weight, administration of Atomoxetine is initiated as a total daily dose of 0.5 mg/kg/day up to a target total daily dose of approximately 1.2 mg/kg either as a single daily dose or as evenly divided doses.

An easy-to-swallow oral liquid formulation of atomoxetine could facilitate accurate dosing through titration. In addition, it could offer improved patient compliance and convenience, particularly in patients with dysphagia (who have difficulty swallowing capsules).

Due to the pediatric use for this product candidate, Hyloris deployed an innovative taste masking strategy targeting a preferred taste for young patients.

For the U.S. market, a pivotal clinical study is in preparation as previously announced.
