Investigation Launched Against Supernus Pharmaceuticals, Inc. over Failure of SPN-820 Clinical Trial
On April 7, 2025, Levi & Korsinsky, a prominent securities law firm, announced the initiation of an investigation into Supernus Pharmaceuticals, Inc. (SUPN) following the company’s disappointing announcement regarding the Phase 2b study of its lead compound, SPN-820, for treatment-resistant depression. The study, which was conducted in collaboration with the National Institute of Mental Health (NIMH), did not meet its primary endpoint, showing no significant improvement over placebo.
Background on Supernus Pharmaceuticals and SPN-820
Supernus Pharmaceuticals, Inc. is a specialty pharmaceutical company headquartered in Rockville, Maryland. The company specializes in developing and commercializing products for the treatment of central nervous system disorders. SPN-820 is an investigational drug that is designed to provide rapid and sustained antidepressant effect. It is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI) and a 5-HT1A receptor partial agonist.
Impact on Supernus Pharmaceuticals and the Stock Market
The failure of the Phase 2b study sent shockwaves through the investment community, leading to a sharp decline in Supernus Pharmaceuticals’ stock price. The company’s shares dropped by over 30% in after-hours trading following the announcement. The investigation by Levi & Korsinsky could potentially lead to securities class action lawsuits against the company, further impacting its share price and reputation.
Implications for Treatment-Resistant Depression Patients
The failure of the SPN-820 study is a setback for the millions of people worldwide who suffer from treatment-resistant depression. The condition, which affects approximately 30% of people with major depressive disorder, is characterized by a lack of response to two or more adequate antidepressant trials. The lack of effective treatments for treatment-resistant depression has been a significant challenge for both patients and healthcare providers.
Future of Supernus Pharmaceuticals and SPN-820
Supernus Pharmaceuticals is not entirely reliant on SPN-820 for its success. The company has a diverse portfolio of products and pipeline, including the approved drug Jadenu (adrenocorticotropic hormone injection) for the replacement therapy of Addison’s disease and the investigational drug SPN-604 for the treatment of attention deficit hyperactivity disorder (ADHD). However, the failure of the SPN-820 study could impact the company’s resources and focus moving forward.
