NEURELIS SECURES NEW ORANGE BOOK LISTED U.S. PATENT FOR VALTOCO® (DIAZEPAM NASAL SPRAY) CIV
SAN DIEGO, CA — [November 27, 2023] — Neurelis, Inc., a neuroscience company focused on the development and commercialization of therapeutics for the treatment of epilepsy and orphan neurologic disorders characterized by high unmet medical need, announced that it has secured the issuance of United States Patent No. 11,793,786 (the ‘786 Patent). The ‘786 Patent covers VALTOCO® and other pharmaceutical solutions for nasal administration consisting of diazepam or a pharmaceutically acceptable salt thereof in combination with specific ranges of one or more natural or synthetic tocopherols or tocotrienols, benzyl alcohol, and n-dodecyl beta-D-maltoside.
The ‘786 Patent is listed in the U.S. Food and Drug Administration (FDA) publication Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, as it relates to VALTOCO®, and is solely owned by Neurelis.
“We are pleased by our continued progress with the United States Patent and Trademark Office and the repeated recognition of the inventive nature of our VALTOCO franchise,” said Craig Chambliss, President and Chief Executive Officer of Neurelis. “We will continue to expand our intellectual property, memorializing the scientific innovation that drives Neurelis’ commitment to improving patient outcomes. This innovation drives our expectations and efforts to extend VALTOCO’s exclusivity even further.”
The ‘786 Patent, with an expiry date of March 2029, joins five other Orange Book listed patents that currently provide exclusivity to the VALTOCO franchise through 2029. As an immediate treatment for frequent seizure activity for patients with epilepsy six years of age or older, VALTOCO empowers patients and care partners to take a proactive role in managing their disease and improve their health outcomes.
Neurelis, Inc., is a neuroscience company focused on the development and commercialization of therapeutics for the treatment of epilepsy and orphan neurologic disorders characterized by high unmet medical needs. In 2020, the FDA 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 6 years of age and older. VALTOCO is a proprietary formulation of diazepam incorporating the science of INTRAVAIL®. Intravail's transmucosal absorption enhancement technology enables the noninvasive delivery of a broad range of protein, peptide and small-molecule drugs. In its approval of VALTOCO, the U.S. Food and Drug Administration also granted Neurelis Orphan Drug Exclusivity and recognized VALTOCO's intranasal route of administration as a clinically superior contribution to patient care of the previously approved standard-of-care treatment (a rectal gel formulation of diazepam).

In addition, Neurelis is developing NRL-1049 (previously known as BA-1049), an investigational, Phase I stage small molecule in 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
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 6 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.
Benzodiazepines, including VALTOCO, can increase intraocular pressure in patients with glaucoma. VALTOCO may 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.
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.
