Knight Therapeutics Enters into Exclusive License Agreement with Supernus Pharmaceuticals for Qelbree® (viloxazine) in Canada

MONTREAL, Dec. 19, 2023 (GLOBE NEWSWIRE) — Knight Therapeutics Inc. (TSX: GUD) ("Knight"), a pan-American (ex-USA) specialty pharmaceutical company, announced today that it has entered into an exclusive license agreement with Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN) ("Supernus"), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, granting Knight the rights to seek regulatory approval and commercialize Qelbree® in Canada. Qelbree® is an extended-release formulation of viloxazine, a multimodal serotonergic and norepinephrine modulating agent (SNMA), a nonstimulant medication for the treatment of Attention-Deficit Hyperactivity Disorder (ADHD). Financial terms of the agreement were not disclosed.

Qelbree® (viloxazine extended-release capsules) is commercially available in the United States as a prescription medicine to treat ADHD in patients 6 years of age and older. Based on the results of 4 pivotal trials,1-4 Qelbree® was approved by the US Food and Drug Administration in 2021 for the treatment of children 6-17 years of age and in 2022 for the treatment of adults. Qelbree® is also currently being studied in several phase 4 clinical trials5, the first of which is in combination with psychostimulants for the treatment of children and adolescents with ADHD (positive topline results reported in September 20236). A second phase 4 clinical trial7 in preschool age children with ADHD is planned to commence in January 2024. A third phase 4 clinical trial9 is studying the impact of Qelbree® on co-morbid mood symptoms prevalent in patients with ADHD.

“This partnership represents the continued execution of our strategy of expanding our presence in CNS and entering in one of the most important segments still presenting relevant unmet medical needs,” said Samira Sakhia, President and CEO of Knight. “We are excited to pursue regulatory approval and bring a novel nonstimulant medication to enhance treatment of patients living with ADHD.”

Supernus was able to identify in Knight the right commercial experience and capabilities to get Qelbree® approved and successfully launch it in Canada," said Jack Khattar, President and CEO of Supernus Pharmaceuticals. "Supernus is proud to support other regions and patients in need of innovative solutions to overcome the challenges of treating a complex disease such as ADHD."

About ADHD8

ADHD is a neurodevelopmental disorder that affects both children and adults. The estimated prevalence of ADHD is 5-9% in children and 3-5% in adults. The disorder is characterized by symptoms of inattention, hyperactivity, and impulsivity that can significantly impact an individual’s ability to function in daily life. Although patients’ symptoms of ADHD can change over time, they will generally require continued monitoring and treatment over their lifetime. Current pharmacotherapies for ADHD include amphetamine or methylphenidate-based psychostimulants as well as long-acting non-psychostimulant options. However, not all patients respond to existing therapies. As a result, there remains a significant medical need for additional treatment options for patients with ADHD.
