Supernus Pharmaceuticals, Inc. (Supernus) operates as a biopharmaceutical company focuses on developing and commercializing products for the treatment of central nervous system (CNS) diseases.
The company's diverse neuroscience portfolio includes approved treatments for attention-deficit hyperactivity disorder (ADHD), dyskinesia in Parkinson's Disease (PD) patients receiving levodopa-based therapy, hypomobility in PD, epilepsy, migraine, cervical dystonia, and chronic sialorrhea. The company is developing a broad range of novel CNS product candidates, including new potential treatments for epilepsy, depression, and other CNS disorders.
Strategy
The key elements of the company's strategy are to drive growth and profitability; advance product candidates toward commercialization; continue to grow its pipeline; and target strategic business development opportunities.
Commercial Products
The company's commercial products, including those sold by or through its subsidiaries, include:
Qelbree
Qelbree (viloxazine extended-release capsules) is a novel non-stimulant product indicated for the treatment of ADHD in adults and pediatric patients 6 years and older. On April 2, 2021, the FDA approved Qelbree for the treatment of ADHD in pediatric patients 6 to 17 years of age. In May 2021, the company launched Qelbree for pediatric patients in the U.S. On April 29, 2022, the FDA approved Qelbree for the treatment of ADHD in adult patients. The company launched Qelbree for adult patients in May 2022. In January 2025, the FDA approved an expanded label update for Qelbree to include new data on the pharmacodynamics and use in breastfeeding mothers.
GOCOVRI
GOCOVRI (amantadine) extended-release capsules is the first and only FDA-approved medicine indicated for the treatment of dyskinesia in patients with PD receiving levodopa-based therapy, with or without concomitant dopaminergic medications, and as an adjunctive treatment to levodopa/carbidopa in patients with PD experiencing ‘off’ episodes.
GOCOVRI was approved by the FDA in August 2017 for the treatment of dyskinesia and in February 2021 as an adjunctive treatment for ‘off’ episodes. The February 2021 update to the label indication makes GOCOVRI the only medicine clinically proven and approved to reduce both ‘off’ episodes and dyskinesia in PD patients taking a levodopa-based medication, resulting in a clinically meaningful increase in good ‘on’ time without the need for a ‘trade-off’ when managing these motor complications.
Oxtellar XR
Oxtellar XR is indicated for the treatment of partial-onset seizure in adults and children 6 years of age and older. Oxtellar XR is the first once-daily extended-release oxcarbazepine product indicated for the treatment of epilepsy in the U.S. market. In 2013, the company launched Oxtellar XR for adjunctive therapy in the treatment of partial-onset seizures in adults and children 6 to 17 years of age. In January 2019, the company launched Oxtellar XR for monotherapy treatment of partial onset epilepsy seizures in adults and children 6 to 17 years of age.
APOKYN
APOKYN (apomorphine hydrochloride injection) is a product indicated for the acute, intermittent treatment of hypomobility or off episodes (end-of-dose wearing off" and unpredictable on-off episodes) in patients with advanced PD. APOKYN's adjustable dose subcutaneous injection pen is designed to quickly and reliably reverse the effects of oral levodopa wearing off in patients with inadequately controlled PD.
Trokendi XR
Trokendi XR is indicated for epilepsy: initial monotherapy for the treatment of partial-onset and primary generalized tonic-clonic (PGTC) seizure in patients 6 years of age and older (1.1); adjunctive therapy for the treatment of partial-onset, primary generalized tonic-clonic seizures, or seizures associated with Lennox-Gastaut Syndrome in patients 6 years of age and older (1.2); and for preventive treatment of migraine in patients 12 years of age and older. Trokendi XR is the first once-daily extended-release topiramate product indicated for the treatment of epilepsy and the prophylaxis of migraine headaches in adults and adolescents in the U.S. market.
XADAGO
XADAGO (safinamide) is a once-daily product indicated as adjunctive treatment to levodopa/carbidopa in patients with PD who are experiencing off episodes. XADAGO is a monoamine oxidase B (MAO-B) inhibitor that works by blocking the catabolism of dopamine, which is believed to result in an increase in dopamine levels, and therefore a subsequent increase in dopaminergic activity in the brain. XADAGO was approved by the FDA in March 2017.
The company has entered into settlement agreements with third parties permitting the sale of a generic version of XADAGO beginning in December 2027, or sooner under certain conditions.
MYOBLOC
MYOBLOC (rimabotulinumtoxinB) is a product indicated for the treatment of cervical dystonia to reduce the severity of abnormal head position and neck pain associated with cervical dystonia in adults and treatment of chronic sialorrhea in adults. MYOBLOC is the only Type B toxin available on the market. MYOBLOC injections must be administered by a physician.
MYOBLOC was approved by the FDA in August 2019 for the treatment of chronic sialorrhea in adults and in December 2000 for the treatment of adults with cervical dystonia.
ONAPGOTM
ONAPGO (apomorphine hydrochloride) injection is the first and only subcutaneous apomorphine infusion device for the treatment of motor fluctuations in adults with advanced PD. ONAPGO was approved by the FDA in February 2025 and received an Orphan Drug Designation. ONAPGO will be launched in the second quarter of 2025.
Research and Development
The company's research and development expenses included $108.8 million in 2024.
The company also engages in a variety of research and development efforts, including the development of a pipeline of novel CNS product candidates for the treatment of various CNS conditions. The company has devoted, and continues to devote, significant resources to research and development activities.
ONAPGO (formerly SPN-830)
ONAPGO (apomorphine hydrochloride) injection is the first and only subcutaneous apomorphine infusion device for the treatment of motor fluctuations in adults with advanced PD. ONAPGO was approved by the FDA in February 2025 and received an Orphan Drug Designation. ONAPGO will be launched in the second quarter of 2025.
The approval of ONAPGO is based on results from a Phase 3, twelve-week, multicenter, parallel-group, double-blind, randomized, placebo-controlled study (N=107) evaluating the efficacy and safety of ONAPGO. The primary efficacy endpoint was the mean change in total daily ‘off’ time assessed from baseline to the end of the twelve-week treatment period based on patient diaries. The key secondary endpoints were the mean change in daily GOOD ON time, which was defined as on time without troublesome dyskinesia, and Patient Global Impression of Change (PGIC).
During the Phase 3 study, ONAPGO significantly reduced the amount of daily ‘off’ time at twelve weeks from baseline (p=0.0114), with ONAPGO-treated patients (n=53) experiencing a 2.6-hour reduction compared to placebo (n=51) with 0.9 hours. The reduction in daily ‘off’" time was accompanied by a similar significant increase in daily GOOD on time (2.8 hours for ONAPGO-treated patients compared to 1.1 hours for the placebo group; p=0.0188). In addition, numerically greater improvements in daily ‘off’ time and daily GOOD on time were seen as early as the first week of treatment and were maintained throughout all measured timepoints. Additionally, ONAPGO-treated patients more frequently reported improvement in their state of general health compared with placebo-treated patients (PGIC: 79% vs. 24%; p<0.0001). The most common adverse events (=10% incidence) were infusion-site nodule, nausea, somnolence, infusion-site erythema, dyskinesia, headache, and insomnia.
SPN-817 (huperzine A)
SPN-817 represents a novel MOA for an anticonvulsant. SPN-817 is a novel synthetic form of huperzine A, whose MOA includes potent acetylcholinesterase inhibition, with pharmacological activities in CNS conditions such as epilepsy. The development will initially focus on the drug's anticonvulsant activity, which has been shown in preclinical models to be effective for the treatment of partial seizures and Dravet Syndrome. SPN-817 has received Orphan Drug Designation for both Dravet Syndrome and Lennox-Gastaut Syndrome from the FDA.
The company focuses on completing and optimizing the synthesis process of the synthetic drug, as well as developing a novel dosage form. Given the potency of SPN-817 (huperzine A), a novel extended-release oral dosage form is critical to the success of this program because initial studies with the immediate-release formulations of non-synthetic SPN-817 (huperzine A) have shown serious dose-limiting, side effects.
The company is conducting an open-label Phase 2a clinical study of SPN-817 in patients with treatment-resistant seizures. The first part of this study (Stage A) has completed dosing in the titration and maintenance periods. The company has completed enrollment of Stage A and announced, in November 2024, the topline data from all subjects with focal seizures who received the 3mg and 4mg twice daily doses, completed the maintenance period (n=10), and enrolled in the post-maintenance extension period (n=6).
SPN-820 (NV-5138)
SPN-820 is a first-in-class, orally active small molecule that activates the brain mechanistic target of rapamycin complex 1 (mTORC1), a gatekeeper of cellular metabolism and renewal. SPN-820 binds to and modulates sestrin, which senses amino acid availability in the brain, a potent natural activator of mTORC1.
Depression is associated with synapse loss and reduced synaptic plasticity in key brain regions, including the prefrontal cortex, and increasing mTORC1-mediated synaptic plasticity is a promising avenue to treat depression and associated symptoms. SPN-820 selectively binds to intracellular sestrin proteins and subsequently engages a cascade of multi-protein complexes, enhancing mTORC1 signaling. A single administration of SPN-820 rapidly (within one hour) and transiently (within seven hours) enhances intracellular mTORC1 signaling in the prefrontal cortex of animals, restores levels of synaptic proteins, and reduces depressive-like behaviors in a brain-derived neurotrophic factor (BDNF)-dependent manner. The rapid and transient enhancement of mTORC1 signaling in the prefrontal cortex is required for anti-depressant effects in preclinical animal models. The intracellular mechanism of SPN-820, as well as the lack of binding to cell surface receptors, suggests the potential for a differentiated safety profile.
A Phase 1 trial demonstrated early proof of concept in which a single dose of SPN-820 showed a rapid and sustained improvement in core symptoms, with favorable safety and tolerability in patients with treatment resistant depression.
The company completed a Phase 2a multi-center open label study in 40 subjects with Major Depressive Disorder (MDD) in the fourth quarter of 2024. The data were based on 40 enrolled subjects, of which 38 completed the ten-day treatment period. The primary objective of the study was to assess efficacy in MDD, as well as the onset of efficacy. The Phase 2a study demonstrated a rapid and substantial decrease in depressive symptoms, along with an 80% decrease in suicidal ideation. SPN-820 was well-tolerated during the study, with few adverse events reported by the subjects. In addition, the data demonstrated a rapid Montgomery–Asberg Depression Rating Scale (MADRS) response rate (=50% reduction) and remission (MADRS =10), reaching 50.0% and 35.0% of subjects, respectively, at 4 hours, with additional improvement to 84.2% and 63.2% of participants by Day 10.
In February 2025, the company reported topline results from the Phase 2b study of SPN-820. The Phase 2b study of SPN-820 in adults with treatment-resistant depression did not demonstrate a statistically significant improvement on the primary endpoint of change from baseline in the MADRS total score to Week 4 (SPN-820 [LS mean ± Standard Error]: -12.3 ± 0.96 vs. placebo: -11.9 ± 0.96; p = not significant). There was no treatment difference between SPN-820 and placebo in the change from baseline to Week 4 for the secondary endpoints. The safety profile of SPN-820 was consistent with previous clinical trials, showing few adverse events.
The Phase 2b study was a multi-center randomized double-blind placebo-controlled trial of SPN-820 in adults with treatment-resistant depression. The study examined the efficacy and safety of SPN-820 over a course of four weeks of treatment, followed by a week of blinded placebo washout in approximately 250 patients from around 40 clinical sites. The primary outcome measure was the change from baseline to the end of the treatment period on the MADRS Total Score.
SPN-443 – Novel stimulant for the treatment of ADHD/CNS
The company completed a Phase 1 single dose study in healthy adults in 2024, following submission of an Investigational New Drug Application. The study was a first-in-human, pilot pharmacokinetic study of two oral formulations of SPN-443 in healthy adults. The primary objective of the study was to assess safety and tolerability. This molecule, along with its major metabolites, is an inhibitor of norepinephrine, dopamine, and serotonin, also known as a triple reuptake inhibitor. Both formulations of SPN-443 showed adequate bioavailability and were well tolerated.
