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.

Tarsus Pharmaceuticals, Inc. whose mission is to focus on unmet needs and apply proven science and new technology to revolutionize treatment for patients, starting with eye care, announced that XDEMVY™ (lotilaner ophthalmic solution) 0.25% is now available at pharmacies nationwide for prescription. The U.S. Food and Drug Administration (FDA) approved XDEMVY on July 24, 2023, for the treatment of Demodex blepharitis.
“We are delighted that within weeks of FDA approval, XDEMVY is now available to millions of patients with Demodex blepharitis,” said Bobak Azamian, MD, PhD, Chief Executive Officer and Chairman of Tarsus. “The efforts of our team have created incredible interest in XDEMVY, the first and only approved solution for this highly prevalent disease. I’m so appreciative of our team and our partners who’ve worked diligently to bring this product to eye care providers and patients quickly and seamlessly following regulatory approval. We are proud to introduce XDEMVY to the eye care community and look forward to its potential to significantly change the way this disease is treated.”
XDEMVY is the only FDA approved treatment to directly target Demodex mites, the root cause of Demodex blepharitis. Demodex blepharitis is characterized by redness, inflammation, missing or misdirected eyelashes, itching along the eyelid base, and the presence of collarettes. XDEMVY is a prescription eye drop that is administered with one drop in each eye twice daily (approximately 12 hours apart) for 6 weeks.
Tarsus is committed to ensuring that patients have affordable and broad access to XDEMVY and developed Tarsus Connect, a suite of assistance programs that provide financial support for eligible patients. More information about Tarsus Connect can be found on xdemvy.com or by calling: 1-866-846-3092.
About Demodex Blepharitis
Blepharitis is a common lid margin disease that is characterized by eyelid margin inflammation, redness and ocular irritation. Demodex blepharitis is caused by an infestation of Demodex mites, the most common ectoparasite found on humans and accounts for over two-thirds of all blepharitis cases. Demodex blepharitis may affect as many as 25 million Americans based on an extrapolation from the Titan study indicating 58% of patients presenting to U.S. eye care clinics have collarettes, a pathognomonic sign of Demodex mite infestation, and that at least 45 million people annually visit an eye care clinic. Demodex blepharitis can have a significant clinical burden and negative impact on patients’ daily lives. The Titan study also showed that current management tools, such as tea tree oil and lid wipes, are ineffective at targeting the root cause of Demodex blepharitis.
About XDEMVY™
XDEMVY (lotilaner ophthalmic solution) 0.25%, formerly known as TP-03, is a novel prescription eye drop for the treatment of Demodex blepharitis and is designed to target and eradicate the root cause of the disease – Demodex mite infestation. The active ingredient in XDEMVY is lotilaner, a well-characterized agent that eradicates Demodex mites by selectively inhibiting the GABA-Cl channels. It is a highly lipophilic molecule, which may promote its uptake in the oily sebum of the eyelash follicles where the mites reside. XDEMVY was evaluated in two pivotal trials collectively involving more than 800 patients. Both trials met the primary endpoint and all secondary endpoints, with statistical significance and no serious treatment-related adverse events. Most patients found XDEMVY to be neutral to very comfortable. The most common ocular adverse reactions observed in the studies were site stinging and burning which was reported in 10% of patients. Other ocular adverse reactions reported by less than 2% of patients were chalazion/hordeolum (stye) and punctate keratitis.

Tonix Pharmaceuticals Holding Corp. a biopharmaceutical company, today announced the completion of the clinical phase of the Phase 2 proof-of-concept PREVAIL study of TNX-102 SL as a potential treatment for fibromyalgia-type Long COVID. Topline results for the PREVAIL study are expected in the third quarter of 2023.
“Approximately 40% of U.S. Long COVID patients have fibromyalgia-like multi-site pain symptoms based on our observational studies of Long COVID patients from the TriNetX claims database,”2,3 said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In addition to multi-site pain, these individuals often suffer from one or more other symptoms typically associated with fibromyalgia such as fatigue, sleep disturbance, and brain fog. We have termed this subgroup, ‘Fibromyalgia-type Long COVID.’ Given our encouraging results with TNX-102 SL as a potential treatment for fibromyalgia4, we are testing TNX-102 SL as a bedtime medicine for the management of Fibromyalgia-type Long COVID. In completing this clinical milestone, marked by the last enrolled patient finishing their final visit, we can now begin to look forward to topline results from the 63-patient PREVAIL study later this quarter.”
Dr. Lederman continued, “TNX-102 SL improves sleep quality in fibromyalgia, and we believe this is the mechanism by which TNX-102 SL improves other symptoms, like multi-site pain.5 Recently, the U.S. National Institutes of Health (NIH) has identified improving sleep quality as a target for potential therapeutics for Long COVID6,7,8, consistent with the proposed mechanism of TNX-102 SL.
“Common symptoms of Long COVID, including multi-site pain, fatigue, unrefreshing sleep, and cognitive dysfunction, or ‘brain fog,’ are also hallmarks of conditions like fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME),”9 said Herbert Harris, M.D., Ph.D., Executive Vice President and Head of Translational Medicine of Tonix Pharmaceuticals. “Defining subgroups of Long COVID patients that overlap with fibromyalgia and CFS/ME is expected to facilitate the development of new treatments.4 It can be challenging to distinguish fibromyalgia and CFS/ME clinically, given the high level of symptom overlap between them. Each of these conditions is defined by a constellation of symptoms, and there is no widely recognized diagnostic laboratory test that distinguishes them.”
Dr. Harris continued, “The recent identification of Long COVID subgroups in the National Institutes of Allergy and Infectious Diseases (NIAID)-sponsored RECOVER study10 was an important step. In their recent publication, cluster analysis of the symptom frequencies in the RECOVER study identified four subgroups of Long COVID patients. Cluster #4 represented approximately one-quarter of the population (28%) and reported the highest frequencies of pain (back pain (58%), joint pain (64%) or muscle pain (60%)), high frequencies of fatigue (94%) and ’Brain Fog,’ (94%) and a high level of impairment of Quality of Life. We believe Cluster #4 is a subgroup of Long COVID that shares many clinical features with fibromyalgia and may involve common disease mechanisms. We also believe that Cluster #3, representing another approximately 29% of the RECOVER cohort, includes many patients with fibromyalgia-type Long COVID because 100% of that group suffer from ‘Brain Fog’, 94% experience fatigue and approximately one-third
experience pain (back pain (32%), joint pain (36%) or muscle pain (34%)).”
Dr. Harris concluded, “With no FDA approved treatment for Long COVID, we understand the need to better understand long COVID and to develop treatments for subgroups of this unserved population of patients. Fibromyalgia has been recognized by the U.S. Food and Drug Administration (FDA) with three approved medicines. Consequently, measuring daily pain is a validated endpoint for FDA registrational studies in fibromyalgia. We believe that daily pain has the potential to be an endpoint for registrational studies in fibromyalgia-like long COVID.”
About the Phase 2 PREVAIL Study
The Phase 2 PREVAIL study is a 14-week double-blind, randomized, multicenter, placebo-controlled study to evaluate the efficacy and safety of TNX-102 SL taken daily at bedtime in patients with multi-site pain associated with post-acute sequelae of SARS-CoV-2 infection (PASC). The trial is being conducted at approximately 30 sites in the U.S. The primary efficacy endpoint will be the change from baseline in the weekly average of daily self-reported worst pain intensity scores at the Week 14 endpoint. Key secondary efficacy endpoints include change from baseline in self-reported scores for sleep disturbance, fatigue, and cognitive function. Topline results are expected in the third quarter of 2023.
About Long COVID or Post-Acute Sequelae of COVID-19 (PASC)
Post-acute sequelae of COVID-19, or PASC is the formal name for a condition now widely known as Long COVID. Although most people recover from COVID-19 within weeks of the acute illness, a substantial portion develops a chronic syndrome called Long COVID.11 These individuals experience a constellation of disabling symptoms long past the time of recovery from acute COVID-19. Most Long COVID patients who have been studied appear to have cleared the SARS-CoV-2 infection from their systems. The symptoms of Long COVID can include fatigue, sleep disorders, multi-site pain, fevers, shortness of breath, cognitive impairment described as “brain fog” or memory disturbance, gastrointestinal symptoms, anxiety, and depression. According to the Centers for Disease Control and Prevention (CDC), 1 in 13 adults in the U.S. (7.5%) have Long COVID symptoms.1 Long COVID is typically associated with moderate or severe COVID-19, but can occur after mild COVID-19 or even after asymptomatic SARS-CoV-2 infection. More than 40% of adults in the United States reported having COVID-19 in the past, and nearly one in five of those (19%) are currently still having symptoms of Long COVID.1 Long COVID is a chronic disabling condition that is expected to result in a significant global health and economic burden.12-15
