Catalyst Pharmaceuticals, Inc. announced the completion of its acquisition from Santhera Pharmaceuticals Holdings of an exclusive license for North America for vamorolone, a potential treatment for patients suffering with Duchenne Muscular Dystrophy. The license is for exclusive commercial rights in the U.S., Canada, and Mexico, as well as the right of first negotiation in Europe and Japan should Santhera pursue partnership opportunities. Additionally, Catalyst will hold North American rights for any future approved indications of vamorolone.
Vamorolone is a promising best-in-class dissociative anti-inflammatory steroid treatment for Duchenne Muscular Dystrophy ("DMD"). In clinical studies, vamorolone demonstrated efficacy with a significant reduction of steroid-associated side effects and benefits for bone health, growth, and behavior, offering the potential to address an important unmet medical need in DMD patients. Vamorolone has received FDA Orphan Drug and Fast Track designations and has been granted a PDUFA action date of October 26, 2023.
"With the addition of vamorolone, we have accomplished another important milestone in the execution of our portfolio expansion strategy," stated Patrick J. McEnany, Chairman and CEO of Catalyst. "The license for vamorolone reflects our strategic focus on opportunities where we can not only apply novel technology to address critical unmet patient needs, but where we can leverage Catalyst's existing integrated capabilities and infrastructure to commercialize the drug efficiently. We believe that vamorolone, if approved, has the potential to deliver significant near and long-term value and to be a very meaningful advancement to the current standard of care paradigm for DMD patients."
Mr. McEnany continued, "Vamorolone fortifies our neuromuscular portfolio with an innovative therapy that, in clinical studies, demonstrated an enhanced safety and tolerability profile as compared to prednisone. We plan to include vamorolone for DMD patients in our Catalyst Pathways® specialty pharmacy program to help ensure that all patients have access to the full patient benefits of the program. Our planned strategy to facilitate access to vamorolone underscores our steadfast commitment to improving the lives of patients suffering from rare neurological conditions."
Duchenne Muscular Dystrophy, or DMD, the most common form of muscular dystrophy, is a rare, fatal neuromuscular disorder characterized by progressive muscular dysfunction, leading to loss of ambulation, respiratory failure, and death. Corticosteroids are the current standard of care for treating DMD; however, this treatment is associated with significant side effect burdens. The U.S. prevalence for DMD is estimated to be between 11,000 and 13,000 patients. Of patients currently being treated for DMD, approximately 75% receive concomitant steroid treatment.
Vamorolone Commercial Operational Plan
Catalyst expects to launch vamorolone early in the first quarter of 2024, assuming regulatory approval on the PDUFA date of October 26, 2023. Catalyst anticipates minimal sales and marketing personnel expansion with fewer than 10 additional team members required, resulting from the exceptional synergy within its existing neuromuscular franchise. Catalyst plans to incorporate vamorolone for DMD into its Catalyst Pathways® specialty pharmacy program to ensure that patients have access to full patient benefits.
About Vamorolone
Vamorolone is an investigational drug candidate with a mode of action based on binding to the same receptor as glucocorticoids but modifying its downstream activity and as such, is considered a dissociative anti-inflammatory steroid drug [2-5]. This mechanism has shown the potential to 'dissociate' efficacy from steroid safety concerns, and therefore vamorolone could emerge as an alternative to existing corticosteroids, the current standard of care in children, adolescent, and adult patients with DMD. In the pivotal VISION-DMD study, vamorolone met the primary endpoint Time to Stand (TTSTAND) velocity versus placebo (p=0.002) at 24 weeks of treatment and showed a good safety and tolerability profile [1]. The most commonly reported adverse events versus placebo from the VISION-DMD study were cushingoid features, vomiting, and vitamin D deficiency. Adverse events were generally of mild to moderate severity.
Vamorolone has been granted Orphan Drug status for DMD in the U.S. and Europe and has received Fast Track and Rare Pediatric Disease designations by the U.S. FDA and Promising Innovative Medicine (PIM) status from the UK MHRA for DMD. Vamorolone is an investigational medicine and is currently not approved for use by any health authority.
About Duchenne Muscular Dystrophy
Duchenne Muscular Dystrophy ("DMD") is a rare inherited X-chromosome-linked disease, which almost exclusively affects males. DMD is characterized by muscle inflammation and damage which are present at birth or shortly thereafter. Inflammation leads to fibrosis of muscle and is clinically manifested by progressive muscle degeneration and weakness. Major milestones in the disease are the loss of ambulation, the loss of self-feeding, the start of assisted ventilation, and the development of cardiomyopathy. DMD reduces life expectancy to before the fourth decade due to respiratory and/or cardiac failure. Corticosteroids are the current standard of care for the treatment of DMD.

Tonix Pharmaceuticals Holding Corp. a biopharmaceutical company, announced that it has completed enrollment of its potentially final, confirmatory Phase 3 RESILIENT trial of TNX-102 SL (cyclobenzaprine HCL sublingual tablets) 5.6 mg in fibromyalgia and expects topline data next quarter. A total of 457 participants were randomized. TNX-102 SL is in development as a non-opioid, centrally acting analgesic, to be taken daily at bedtime for the management of fibromyalgia. If successful, we believe this will be the final, well-controlled efficacy trial required for submission of a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA).
“The completion of enrollment in our Phase 3 RESILIENT trial is a significant milestone for both Tonix and the fibromyalgia community,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “Currently-approved treatments have not fully met the needs of fibromyalgia patients and there has not been a new FDA-approved therapy for the condition since 2009. TNX-102 SL has the potential to be a new non-addictive, non-opioid bedtime medication with broad spectrum symptom coverage and which can be used on a chronic basis for the management of fibromyalgia. With all other clinical, nonclinical and CMC requirements for an NDA submission achieved, we are looking forward to the upcoming data readout and an expeditious filing of an NDA.”
In December 2020, Tonix reported positive results from the first Phase 3 study (RELIEF) of TNX-102 SL 5.6 mg for the management of fibromyalgia. TNX-102 SL met its pre-specified primary endpoint in the Phase 3 RELIEF trial, significantly reducing daily pain compared to placebo (p=0.01) in participants with fibromyalgia. Also, when the primary endpoint was analyzed as a ≥30% pain responder analysis, there was a higher rate of responders to TNX-102 SL (47%) than to placebo (35%; p=0.006). TNX-102 SL at 5.6 mg also showed activity in key secondary endpoints demonstrating improvements in sleep quality, mitigation of fatigue, and fibromyalgia-specific global symptomatic and functional recovery. TNX-102 SL was generally safe and well tolerated in patients with fibromyalgia, with overall adverse event profile comparable to prior fibromyalgia studies. The most common treatment-emergent adverse events were oral hypoesthesia, oral paresthesia, and product taste abnormal.
About the Phase 3 RESILIENT Study
The RESILIENT study is a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the management of fibromyalgia. The two-arm trial randomized 457 participants in the U.S. The first two weeks of treatment consist of a run-in period in which participants start on TNX-102 SL 2.8 mg (1 tablet) or placebo. Thereafter, all participants increase their dose to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for the remaining 12 weeks. The primary endpoint is the daily diary pain severity score change (TNX-102 SL 5.6 mg vs. placebo) from baseline to Week 14 (using the weekly averages of the daily numerical rating scale scores), analyzed by mixed model repeated measures with multiple imputation.
About Fibromyalgia
Fibromyalgia is a chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system. Fibromyalgia afflicts an estimated 6-12 million adults in the U.S., approximately 90% of whom are women. Symptoms of fibromyalgia include chronic widespread pain, nonrestorative sleep, fatigue, and morning stiffness. Other associated symptoms include cognitive dysfunction and mood disturbances, including anxiety and depression. Individuals suffering from fibromyalgia struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products.
About TNX-102 SL
TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which provides rapid transmucosal absorption and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypass of first-pass hepatic metabolism. As a multifunctional agent with potent binding and antagonist activities at the 5-HT2A-serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors, TNX-102 SL is in development as a daily bedtime treatment for fibromyalgia, Long COVID (formally known as post-acute sequelae of COVID-19 [PASC]), alcohol use disorder and agitation in Alzheimer’s disease. The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10,357,465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary TNX-102 SL composition. These patents are expected to provide TNX-102 SL, upon NDA approval, with U.S. market exclusivity until 2034/2035.

Tris Pharma, Inc. (Tris), a commercial-stage biopharmaceutical company focused on ADHD, pain, addiction and neurological disorders, today announced that Health Canada has authorized the use of Quillivant® ER (extended release) for the treatment of attention deficit hyperactivity disorder (ADHD) in children ages 6 to 12. Quillivant ER will be available as both an oral suspension and chewable tablet (known in the United States as Quillivant XR® and QuilliChew ER®, respectively). Quillivant ER is the first once-daily, long-acting, chewable and oral suspension formulations of methylphenidate to be approved for the treatment of ADHD in Canada.
“Children with ADHD around the world need medications that provide fast-acting and long-lasting relief in a range of formulations that are easy for them to take. Since the launch of our Quillivant XR product in the United States, we have been approached by potential partners to make our portfolio of ADHD products available around the world,” said Ketan Mehta, founder and chief executive officer at Tris Pharma. “We are truly delighted by this milestone, which will make this important medication available to millions of patients in Canada.”
Ontario-based KYE Pharmaceuticals, Inc. will make Quillivant ER Oral Suspension and Quillivant ER Chewable Tablets available to patients in Canada beginning in Q1 2024. Tris will manufacture Quillivant ER in the United States and export to KYE Pharmaceuticals for Canadian patients.
ADHD is one of the most common neurodevelopmental disorders diagnosed among children. Many therapies approved to treat ADHD have well-established and significant drawbacks, including early symptom rebound, limited duration of release and efficacy, delayed onset, inability to customize or control titration, and patient difficulty taking the medications (e.g., children unable to swallow a tablet).
In Canada, Quillivant ER is authorized for administration to children aged 6 to 12 diagnosed with ADHD as a once-daily liquid suspension or as a chewable tablet to overcome the difficulty of swallowing pills while still achieving the duration needed to control ADHD symptoms for the desired timeframe. Quillivant ER has demonstrated onset of action as soon as 45 minutes through 12 hours post-dose, providing consistent, continuous delivery throughout the day. Quillivant ER Oral Suspension allows for personalized dosing with ease of titration and the Quillivant ER chewable tablets are scored tablets, which are ideal for pediatric patients, providing additional flexibility in dose administration with the most dosing options available in an extended-release methylphenidate tablet. Tris developed both formulations using the company’s proprietary LiquiXR® technology.
“Quillivant ER has the potential to address a significant unmet market need in the treatment of ADHD by overcoming drawbacks associated with many other ADHD medications, particularly among children,” said John McKendry, president at KYE Pharmaceuticals. “Our strategic partnership with Tris allows us to apply our extensive regulatory and commercial expertise to ensure this unique ADHD medication is made available to patients in Canada.”
