VALTOCO maintains orphan drug exclusivity for VALTOCO to treat episodes of frequent seizures SAN DIEGO, April 16, 2025 /PRNewswire/ -- Neurelis, Inc., today announced that the U.S. Food and Drug Administration (FDA) has approved VALTOCO® (diazepam nasal spray) for short-term treatment of seizure clusters (also known as "acute repetitive seizures") that are different from a person's normal seizure pattern in people 2 years of age and older. VALTOCO is a proprietary formulation which utilizes an absorption enhancement technology, INTRAVAIL®, to enable the noninvasive, enhanced intranasal delivery of diazepam. The intranasal formulation of Neurelis' VALTOCO was previously recognized by the FDA as clinically superior to the rectal gel formulation of diazepam resulting in its orphan drug exclusivity designation. "We are so grateful for all those who participated in the clinical study to enable VALTOCO to reach this milestone, especially the patients and families whose participation in the trial helped expand access to a unique immediate-use medication to help stop an episode of frequent seizures," said Craig Chambliss, Neurelis Founder and CEO. "The FDA's decision to approve VALTOCO for use in early childhood highlights the established balanced safety and efficacy profile," commented Eric Segal, MD, Director of Pediatric Epilepsy at Northeast Regional Epilepsy Group and Hackensack University Medical Center. "VALTOCO fills a large unmet need for children with seizures and their families. I am hopeful that this product will improve quality of life for this specific population." Approximately 3.4 million people in the U.S. have epilepsy, including 400,000 children. While chronic epilepsy can be controlled by medications, some patients are at risk of episodes of frequent seizures, or acute repetitive seizures. "For children who have episodes of frequent seizures, the current standard of care requiring rectal administration of medication to stop a seizure can be a significant challenge for caregivers and children alike," added Jurriaan M Peters, MD, PhD, Director, Localization Laboratory, Division of Epilepsy and Clinical Neurophysiology, Boston Children's Hospital, and Associate Professor in Neurology at Harvard Medical School. "Approval of an immediate-use intranasal diazepam treatment that can be given at any time, even while a child is actively seizing, in this young age group is an important advance for the epilepsy community." Data from the phase 1/2a clinical study evaluating safety and pharmacokinetics demonstrated that VALTOCO is safe and effective with easy nasal administration for patients aged 2 years and older who have episodes of frequent seizures. The company presented data on the study at the 53rd Annual Child Neurology Society Meeting in November 2024 in San Diego and Annual American Epilepsy Society Meeting in December 2024 in Los Angeles. About Neurelis Neurelis, Inc., is a neuroscience company focused on the development and commercialization of therapeutics for the treatment of epilepsy and neurologic disorders characterized by high unmet medical need. The FDA has approved Neurelis' VALTOCO® (diazepam nasal spray) as an acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from an individual's usual seizure pattern in adult and pediatric patients 2 years of age and older. VALTOCO is a proprietary formulation of diazepam incorporating the science of INTRAVAIL®, a transmucosal absorption enhancement technology that enables the noninvasive delivery of a broad range of protein, peptide, and small-molecule drugs. For more information on VALTOCO, please visit . For the latest scientific information on VALTOCO, please visit . Neurelis is also developing NRL-1004, an investigational, Phase 1 stage intranasal olanzapine for treatment of acute agitation episodes associated with schizophrenia and bipolar disorder. In addition, Neurelis is also developing NRL-1049 (previously known as BA-1049), an investigational, Phase 1 new chemical entity Rho kinase (ROCK) inhibitor, for the treatment of cerebral cavernous malformations (CCMS), a rare disorder of the central nervous system (CNS).

Important Safety Information about VALTOCO: Indication VALTOCO® (diazepam nasal spray) is indicated for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from a patient's usual seizure pattern in patients with epilepsy 2 years of age and older. Contraindications: VALTOCO is contraindicated in patients with: Hypersensitivity to diazepam Acute narrow-angle glaucoma Central Nervous System (CNS) Depression Benzodiazepines, including VALTOCO, may produce CNS depression. Caution patients against engaging in hazardous activities requiring mental alertness, such as operating machinery, driving a motor vehicle, or riding a bicycle, until the effects of the drug, such as drowsiness, have subsided, and as their medical condition permits. The potential for a synergistic CNS-depressant effect when VALTOCO is used with alcohol or other CNS depressants must be considered, and appropriate recommendations made to the patient and/or care partner. Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including VALTOCO, increase the risk of suicidal ideation and behavior. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or unusual changes in mood or behavior. Glaucoma Benzodiazepines, including VALTOCO, can increase intraocular pressure in patients with glaucoma. VALTOCO may only be used in patients with open-angle glaucoma only if they are receiving appropriate therapy. VALTOCO is contraindicated in patients with narrow-angle glaucoma. Neonatal Sedation and Withdrawal Syndrome Use of VALTOCO late in pregnancy can result in sedation (respiratory depression, lethargy, hypotonia) and/or withdrawal symptoms (hyperreflexia, irritability, restlessness, tremors, inconsolable crying, and feeding difficulties) in the neonate. Monitor neonates exposed to VALTOCO during pregnancy or labor for signs of sedation and monitor neonates exposed to VALTOCO during pregnancy for signs of withdrawal; manage these neonates accordingly. Risk of Serious Adverse Reactions in Infants due to Benzyl Alcohol Preservative VALTOCO is not approved for use in neonates or infants. Serious and fatal adverse reactions, including "gasping syndrome," can occur in neonates and low-birth-weight infants treated with benzyl alcohol–preserved drugs, including VALTOCO. The "gasping syndrome" is characterized by central nervous system depression, metabolic acidosis, and gasping respirations. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known. Adverse Reactions The most common adverse reactions (at least 4%) were somnolence, headache, and nasal discomfort. Diazepam, the active ingredient in VALTOCO, is a Schedule IV controlled substance.

Episode Highlights a Truly Remarkable Patient Story Spanning 79 Years Video features 79-year-old Norma Coles, believed to be among the earliest individuals ever evaluated for Netherton Syndrome and is available on the company’s NETHERTON NOW website ASHBURN, Va., April 10, 2025 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (“Quoin” or the “Company”), a late clinical-stage specialty pharmaceutical company focused on the development and commercialization of therapeutic products that treat rare and orphan diseases, today announced the release of the second episode in its “Living with Netherton” video series, part of the company’s broader NETHERTON NOW awareness campaign. This installment features Norma Coles, a 79-year-old woman whose diagnosis with Netherton Syndrome came decades after she was first evaluated by the condition’s namesake, Dr. Edward Netherton. “Norma’s story thoughtfully bridges the earliest history of Netherton Syndrome with today’s urgent need for awareness and treatment,” said Denise Carter, Co-Founder and Chief Operating Officer of Quoin Pharmaceuticals. “Her powerful story reflects the reality of so many others who continue to go undiagnosed and unsupported. ‘Living with Netherton’ highlights individuals who have gone unheard and unrecognized for far too long, bringing to light the urgent need for effective Netherton Syndrome treatment.” Norma’s story reflects the persistent challenges faced by patients living with this rare genetic disorder, including years of misdiagnosis, lack of awareness and limited medical guidance. For decades, she endured fragile skin, recurring rashes and brittle hair described as “bamboo hair”—a key characteristic of the disease. It wasn’t until her mid-50s that Norma was finally diagnosed, revealing a long-forgotten connection to Dr. Netherton himself, who studied her as a child at the Cleveland Clinic in the late 1940s. “I guess I got it all started,” Norma says in the video, “but I didn’t know about it until I was 58.” Her powerful reflection sheds light on how far the medical community has come, and how far it still must go. Today, 75 years after her first visit to Dr. Netherton, there remains no FDA-approved treatment for Netherton Syndrome. Through the NETHERTON NOW campaign, Quoin is committed to raising awareness, improving education, and building advocacy for individuals and families affected by Netherton Syndrome. The video series is a central part of that effort, sharing real patient experiences to foster understanding of a disease that is often overlooked or misunderstood. “Norma’s story reminds us why our work is critically important,” said Dr. Michael Myers, Co-Founder and Chief Executive Officer of Quoin Pharmaceuticals. “At a time when there are still no FDA-approved treatments for Netherton Syndrome, her experience illustrates both the long road so many patients have traveled and the urgency of delivering a transformative treatment option. Our ongoing clinical trials of QRX003 have generated encouraging initial data, including meaningful improvements in skin healing, clear reductions in painful inflammation and pruritus while leading to a much enhanced quality of life. We remain deeply committed to completing the development of what we hope will become the first approved treatment for this devastating disease. Stories like Norma’s fuel our determination every step of the way.” Quoin’s lead product candidate, QRX003, is currently being evaluated in four clinical trials for the treatment of Netherton Syndrome. The Company’s goal is to develop the first FDA-approved therapy for the condition and provide meaningful support to a community that has waited far too long for answers. The full video featuring Norma Coles can be viewed here https://www.youtube.com/watch?v=FtuiXC_IdXE About QRX003 QRX003 is a topical lotion formulated with a proprietary delivery technology that contains a broad-spectrum serine protease inhibitor, whose mechanism of action is intended to perform the function of a specific protein called LEKTI. The absence of LEKTI in Netherton patients leads to excessive skin shedding, resulting in a highly porous and compromised skin barrier. QRX003 is designed to promote a more normalized skin-shedding process and the formation of a stronger and more effective skin barrier.
