(TSX: GUD) ("Knight"), a pan-American (ex-USA) specialty pharmaceutical company, announced today that Knight's New Drug Submission (NDS) for Qelbree® (viloxazine extended-release capsules) has been accepted for review by Health Canada. Qelbree® is a novel nonstimulant medication for the treatment of Attention-Deficit Hyperactivity Disorder (ADHD).

Knight entered into an agreement in December 2023 with Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN) for the exclusive rights to commercialize Qelbree® in Canada. Qelbree® is commercially available in the United States as a prescription medicine to treat ADHD in patients 6 years of age and older.

Qelbree® is currently being studied in several 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 clinical trial7 in preschool-age children with ADHD was initiated in March 2024. A third clinical trial9 is studying the impact of Qelbree® on adults with ADHD and co-morbid mood symptoms.

“We are excited to announce the submission of Qelbree® in Canada, a novel nonstimulant treatment for ADHD, that offers a new treatment option for patients,” said Samira Sakhia, President and Chief Executive Officer of Knight. “This innovative therapy addresses an important need for those who may not respond well to traditional stimulants or have had a suboptimal response to first-time medication, providing a new option for improved management of ADHD. With the submission of Qelbree®, we continue to further strengthen our ADHD portfolio, offering a range of products designed to meet the diverse needs of patients.”

According to IQVIA Canada, the total Canadian market of non-stimulant ADHD products was $83.5M in 2023. Prescriptions in the Canadian non-stimulant ADHD market grew 10% in 2023 versus 2022 and grew at a CAGR of 11% over the last 4 years, according to IQVIA.

About ADHD8

ADHD is a chronic, often lifelong, neurodevelopmental disorder that affects both children and adults. The estimated prevalence of ADHD is 5-9% in children and adolescents and 3-5% in adults. 8 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.
