Neurelis Announces Program To Investigate The Safety And Pharmacokinetics Of VALTOCO® (Diazepam Nasal Spray) In Children Aged 2 To 5

SAN DIEGO, Sept. 23, 2020 /PRNewswire/ -- Neurelis, Inc., announced today that it will be investigating the safety and pharmacokinetics of the company's lead product, VALTOCO^® (diazepam nasal spray), in children with epilepsy aged two to five. VALTOCO is currently available for adults and pediatric patients 6 years of age and older. This is an investigational program for a patient population not included in the current U.S. Food and Drug Administration-approved (FDA) VALTOCO label. VALTOCO was approved by the FDA on January 10, 2020, for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (ie, seizure clusters, acute repetitive seizures) that are distinct from a patient's usual seizure pattern.

"There is a high unmet need in this younger age group for additional treatment options with a different route of administration that may be administered safely in the middle of a seizure emergency," said Craig Chambliss, the company's President and Chief Executive Officer. "We look forward to continuing to progress our efforts with the FDA to finalize the clinical requirements in this important group of patients."

Upon completion of the clinical study, Neurelis plans to submit a supplemental NDA (sNDA) with the FDA to expand VALTOCO's label to include patients aged 2 and older.  Chambliss said the company plans to file the sNDA in 2021. 

In the United States, there are more than 3.4 million people with epilepsy, with approximately 200,000 new patients diagnosed each year. Despite the availability of daily oral medications to control chronic epilepsy, a significant number of these patients continue to experience seizures. Of these uncontrolled patients, as many as 170,000 are at risk for episodes of frequent seizure activity, also known as cluster or acute repetitive seizures, representing a significant unmet need in the epilepsy community.

About VALTOCO

VALTOCO is a proprietary formulation of diazepam incorporating the science of Intravail^®. Intravail 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 FDA also granted Neurelis Orphan Drug Exclusivity and recognized VALTOCO's intranasal route of administration as a clinically superior contribution to patient care over the previously approved standard-of-care treatment (a rectal gel formulation of diazepam). In a long-term, open-label, repeat-dose clinical trial, the safety of VALTOCO was evaluated and more than 4,000 seizures were treated. The clinical trial included adult and pediatric patients aged 6 and older. VALTOCO was generally safe and well tolerated during clinical studies. The most common adverse reactions for diazepam (at least 4%) were somnolence, headache, and nasal discomfort. For more information on VALTOCO, please visit www.valtoco.com.

About Neurelis

Neurelis, Inc., is an innovation-driven neuroscience company providing a highly differentiated approach to target unmet medical needs. Neurelis is focused on the development and commercialization of product candidates for epilepsy and the broader central nervous system (CNS) market. On January 10, 2020, the U.S. Food and Drug Administration (FDA) approved Neurelis' VALTOCO^® (diazepam nasal spray) as an acute treatment of intermittent, stereotypic episodes of frequent seizure activity (ie, 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. In addition to VALTOCO, the company is developing NRL-2 for intermittent use to control acute panic attacks, NRL-3 as a noninvasive acute therapy to stop seizures that have progressed to status epilepticus, and NRL-4 as a noninvasive rescue therapy to address the escalation of psychomotor agitation (PMA) symptoms outside of the medical setting. The Neurelis technology platform includes Intravail^®, ProTek^® and Hydrogel^™, three proprietary, noninvasive drug-delivery and stabilization technologies applicable to a wide range of molecules, including therapeutic proteins, peptides, non-peptide macromolecules, and small molecules.

Important Safety Information about VALTOCO:

Indication
VALTOCO^® (diazepam nasal spray) is indicated for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (ie, 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.

IMPORTANT SAFETY INFORMATION

RISK FROM CONCOMITANT USE WITH OPIOIDS

Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death.

• Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate
• Limit dosages and durations to the minimum required
• Follow patients for signs and symptoms of respiratory depression and sedation

Contraindications: VALTOCO is contraindicated in patients with:

• Known 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. Advise patients and caregivers to be alert for these behavioral changes and to immediately report them to a healthcare provider.

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.

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.
