SAN DIEGO, CA – January 29, 2018 -- Neurelis announced today that its Intravail® licensing partner, Dr. Reddy’s Laboratories and its U.S. subsidiary, Promius Pharma, LLC, received U.S. Food and Drug Administration (FDA) approval of TOSYMRA™ (sumatriptan nasal spray 10 mg).  TOSYMRA™ is indicated for the acute treatment of migraine with or without aura in adults.

Neurelis President and CEO Craig Chambliss stated, “This is a significant development for migraine sufferers and we congratulate the Dr. Reddy’s team for bringing this important treatment option to market.  It is also an important milestone for Neurelis as TOSYMRA™ is the first product to incorporate Intravail® in an FDA-approved product.”

The science of Intravail® enables the non-invasive delivery of a broad range of protein, peptide and non-peptide drugs.  Intravail® can be utilized via the oral, buccal, dermal, and intranasal administration routes of drug administration, providing several advantages:

  • Increased bioavailability  –  Addressing sub-optimal bioavailability or route-of-administrations

  • Application to wide range of molecules  –  Small molecules, therapeutic proteins, peptides, non-peptide macromolecules (up to ~ 30KDa)

  • Safety  –  Odorless, tasteless, non-toxic, non-mutagenic and non-irritating

  • Solubility in water/oils  –  Compatible with routine liquid formulation and dispensing processes for ease of scale-up and production

VALTOCO™ (diazepam nasal spray), Neurelis’ lead product candidate, is a proprietary formulation of diazepam incorporating the unique combination of a vitamin E-based solution with Intravail®.  Currently under FDA review, Neurelis is preparing for the commercial launch of VALTOCO™ in 2019.

In addition to VALTOCO™, Chambliss said the company’s pipeline utilizes Intravail® to develop novel formulations of drugs targeting areas of significant unmet medical needs in Central Nervous System (CNS) diseases.  Neurelis is also fortunate to partner Intravail® with a number of licensees furthering the development of important drugs in a variety of diseases and continues to expand its strategic partnerships to benefit patients, caregivers, and healthcare providers. 

More About VALTOCO

VALTOCO™ nasal spray is a proprietary formulation of diazepam, delivered via a nasal spray formulation, developed for the management of pediatric, adolescent, and adult patients who require intermittent use of diazepam to control bouts of increased seizure activity, also known as cluster or acute repetitive seizures.  In clinical trials, VALTOCO™ demonstrated high bioavailability, low variability from dose to dose, and was well-tolerated with the most common adverse events being nasal discomfort (seen in 5% of patients in clinical trials).  The FDA previously granted Neurelis both Orphan Drug and Fast Track designations for VALTOCO™.  The NDA for VALTOCO™ is supported by an extensive clinical and pre-clinical package, including studies in healthy volunteers and patients with epilepsy.   In the patient studies, more than 2,000 seizures have been treated to date with VALTOCO™ nasal spray.
