(Nasdaq: SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced data from its exploratory open-label Phase 2a clinical study of SPN-820 in adults with major depressive disorder. The study examined the safety and tolerability of SPN-820 2400 mg given once every 3 days as an adjunctive treatment to the current baseline antidepressant therapy, as well as assessed the rapid onset of improvement in depressive symptoms. The analysis is based on 40 enrolled subjects, of which 38 completed the 10-day treatment period. Summary of the Data Clinically meaningful improvement of –6.1 at two hours and –9.6 at Day 10 on the Hamilton Depression Rating Scale-6 Items (HAM-D6) total score. Clinically meaningful improvement of –16.6 at four hours and –22.9 at Day 10 on the Montgomery Åsberg Depression Rating Scale (MADRS) total score. Suicidal ideation decreased by 80% (12.5% with suicidal ideation at baseline decreased to 2.6% with suicidal ideation at Day 10). SPN-820 was well-tolerated with few adverse events (AEs) and had acceptable tolerability with a discontinuation rate of 2.5% due to AEs. Most common AEs related to the drug included headache, nausea, somnolence, and dizziness. Additional AEs such as cognitive disorder, dry mouth, fatigue, nasal decongestion, and paresthesia oral were observed. “These Phase 2a data underscore our belief that SPN-820 has the potential as a novel treatment option for patients with depression, with the opportunity to decrease symptoms quickly and without certain burdensome side effects,” said Jack Khattar, President and CEO of Supernus. “We expect to complete enrollment in the Phase 2b randomized double-blind placebo-controlled study of SPN-820 in adults with treatment-resistant depression in November of this year, with topline results expected in the first half of 2025.” Webcast Details Supernus will host a conference call and webcast today, October 17, 2024, at 4:30 p.m. ET to discuss these topline results.

About SPN-820 SPN-820 is a first-in-class, orally active small molecule that increases the brain mechanistic target of rapamycin complex 1 (mTORC1) mediated synaptic function intracellularly. SPN-820 is being developed to provide a rapid-onset antidepressant response via oral administration for adult patients with depression. The compound has a novel mechanism of action that enhances synaptic activity and cellular metabolism in the brain and has demonstrated a rapid onset of action (signal at two hours) in early clinical studies. SPN-820 is expected to provide rapid antidepressant efficacy without potential dissociative side effects. A Phase 2b clinical study of SPN-820 in approximately 227 adult patients with treatment-resistant depression is ongoing. About the SPN-820 Phase 2a Clinical Study The study is a Phase 2a open-label study in 40 subjects with major depressive disorder (MDD). The primary objective of the study is to assess efficacy in MDD, as well as onset of efficacy and safety. About Supernus Pharmaceuticals, Inc.

Ahead of ADHD Awareness Month, Busy is sharing her ADHD diagnosis and Qelbree® (viloxazine extended-release capsules) treatment story to empower women living with ADHD to advocate for their care.ADHD often presents differently in women than in men, which can make it more challenging to recognize in women and ultimately leaving them undiagnosed and untreated.1 ROCKVILLE, Md., Sept. 24, 2024 (GLOBE NEWSWIRE) -- In a continued collaboration with Supernus Pharmaceuticals, actress, author, podcaster, late-night host, and mom, Busy Philipps, is speaking up this fall about her ongoing journey with attention-deficit/hyperactivity disorder (ADHD), bringing awareness to the often-overlooked symptoms of the condition in women and Qelbree, a non-stimulant ADHD treatment that has benefitted her. With summer over and the school year now in full swing, the fall season brings for many adults a return to normal routines or schedules, as well as an opportunity for a fresh start. Busy knows first-hand just how difficult getting ‘back to schedule’ can be for the approximately 10 million adults living with ADHD, who may be experiencing symptoms of inattention, hyperactivity/impulsivity, or both.2 She’s sharing her story to help empower people, and especially women, living with ADHD to take action for a fresh start this fall and talk to their doctors about treatment options to help manage their condition. “For many years living with unmanaged ADHD, I’d often start a task and never remember to finish, frequently feeling restless and unable to stay still. I would ramble on, get easily distracted and have trouble multitasking, and with my busy lifestyle, it was a challenge,” says Busy. “Now that I’m taking Qelbree, I’m relieved that my ADHD symptoms are more manageable. I only wish I’d taken charge of my ADHD sooner. That’s why I’m sharing my story to raise awareness about ADHD and help others who may be struggling with their diagnosis find a treatment option that works for them like Qelbree has worked for me.” Qelbree is a novel, once-a-day, non-stimulant approach for patients 6 years and older with ADHD, and the first non-stimulant approved for adults with ADHD in 20 years. As a non-stimulant, Qelbree has no evidence of abuse or misuse and can be conveniently refilled without needing a new prescription each month. “As a leader in treating ADHD, Supernus is committed to providing treatment options and education to help people living with ADHD like Busy Philipps manage their ADHD symptoms,” says Jack A. Khattar, President and Chief Executive Officer of Supernus Pharmaceuticals. “We appreciate Busy’s continued support and willingness to share her ADHD story and experience with Qelbree, especially leading into ADHD Awareness Month.” For more information about Qelbree, visit Qelbree.com. Patients should speak to a doctor about all the medications they take, and to see if Qelbree could be right for them.
