Topline results from Phase IV study demonstrate Qelbree is safe and well-tolerated, and significantly improved efficacy outcomes when added to a stimulant medication in pediatric patients with ADHDFinal long-term data show Qelbree consistently improved symptoms and executive function in adults with ADHD, with safety and tolerability similar to the short-term pivotal adult Phase III trial
ROCKVILLE, Md., Sept. 09, 2023 (GLOBE NEWSWIRE) — Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, announces the presentation of two posters at Psych Congress 2023 with new data showing improved efficacy in children ages 6 years and older with ADHD when Qelbree is added to a stimulant, as well as in adults with ADHD who undergo long-term treatment with Qelbree.
“While ADHD is recognized as one of the most common psychiatric diagnoses, affecting approximately 16.1 million individuals in the United States, patients are in need of alternative or additional options to stimulants that allow them to manage their symptoms with a safe and tolerable treatment option,” says Jonathan Rubin, Chief Medical Officer and Senior Vice President of Research & Development. “The new Qelbree data presented during Psych Congress 2023 reinforce the efficacy and safety of our novel nonstimulant treatment in addition to existing stimulant therapy in children ages 6 and older with ADHD and in a long-term setting in adults with ADHD.”
Results from Phase IV Safety Trial of Concomitant Use with Psychostimulants in Children and Adolescents with ADHD
When added to existing psychostimulants, Qelbree demonstrated a favorable safety and tolerability profile as well as a significant improvement in ADHD symptoms in pediatric patients (6-17 years), regardless of timing of dosing.
In an eight-week, Phase IV, open-label study, children (ages 6-11) and adolescents (ages 12-17) took psychostimulants at least five days a week in the morning throughout the duration of the study, and received Qelbree once-daily in the morning through week four and then switched to evening dosing through week eight; children received 100mg per day of Qelbree at week one and were optimized to 100-400mg per day, and adolescents received 200mg per day of Qelbree at week one and were optimized to 200-600mg per day.
Results showed significant symptom improvement from baseline ADHD-RS-5 and CGI-S scores following both morning and evening dosing of Qelbree in combination with the morning psychostimulant. At baseline (N=56), mean (standard deviation) ADHD-RS-5 and CGI-S scores were 37.2 (8.35) and 4.4 (0.56), respectively, and improved at week four (N=54) by -13.5 (9.7) and -0.9 (0.92), respectively, and at week eight (N=48) by -18.2 (9.99) and -1.4 (1.10), respectively. Reported adverse events (AEs) of the combination therapy included headache (17.9%), decreased appetite (12.5%), and upper respiratory tract infection (10.7%), and 3.6% of patients discontinued the combination treatment due to an AE.
“Approximately 10%-30% of individuals living with ADHD experience inadequate response or have difficulty tolerating stimulant medications, which indicates a clear need for alternative or additional treatment options,” says Ann Childress, M.D., President of the Center for Psychiatry and Behavioral Medicine in Las Vegas, NV. “These data demonstrate Qelbree’s ability to enhance efficacy when co-administered with stimulants, including significant improvement during evening hours when the effects of stimulants often wear off following their morning dose. This study illustrates the versatility of Qelbree to address patient needs, including standalone usage and combination therapy, regardless of dosing time.”
Final Results from Long-term, Phase III, Open-label Extension Trial in Adults with ADHD
Conclusive outcomes from a long-term, open-label extension (OLE) trial of the double-blind pivotal Phase III study that led to the U.S. Food and Administration (FDA)-approval of Qelbree in adults with ADHD, found that adult patients (N=159) saw an improvement in ADHD symptoms and executive function with safety and tolerability similar to the initial trial.
Adults received 200mg of Qelbree every day for one week, increased to 400mg, and then optimized over twelve weeks up to 600mg per day (200-600mg per day). Patients in this open-label trial received Qelbree for 265 (254.9) days.
Patients ADHD symptoms improved from 37.9 (6.34) to 19.7 (12.16) on the Adult ADHD Investigator Symptom Rating Scale (AISRS), representing average symptom reduction of -18.2 (11.54). Patients executive function improved from 70.4 (10.94) to 58.3 (16.19) on the BRIEF-A Global Executive Composite scale, representing improvement in executive function of -12.9 (13.48). The treatment related adverse events (TRAEs) seen in this long-term trial were consistent with those seen in the short-term pivotal adult trial. The most commonly occurring TRAEs reported with the use of Qelbree were insomnia (11.3%), nausea (9.4%), headache (5.7%), and fatigue (10.1%). AEs led to discontinuation in 17.6% of patients.
“ADHD is a 24/7 disorder that often persists into adulthood, and it can be difficult to find the right treatment regimen,” says Andrew J. Cutler, M.D., Clinical Associate Professor of Psychiatry at SUNY Upstate Medical University, and Chief Medical Officer, Neuroscience Education Institute. “These data are encouraging as they underscore the compelling advantage of long-term medication adherence and benefits with Qelbree for our ADHD patients, including sustained improvement in ADHD symptoms, robust response, reduced severity and improved executive function.”
Qelbree® (viloxazine extended-release capsules) is a prescription medicine used to treat ADHD in adults and children 6 years and older.
