SAN DIEGO, CA – February 20, 2019 – Neurelis, Inc. announced today that its Intravail^® licensing partner, ARS Pharmaceuticals, Inc., received Fast Track designation from the FDA for ARS-1, its novel intranasal epinephrine spray. ARS-1 is being investigated as a treatment for patients with severe allergic reactions to food, medications and insect bites that could lead to life-threatening anaphylaxis.

Neurelis President and CEO Craig Chambliss stated, “This latest news provides more validation of Intravail’s crucial role in the development of innovative products targeting areas of high unmet needs. We congratulate the ARS team on the tremendous progress of their ARS-1 treatment, which has the potential to offer people at risk for life-threatening anaphylaxis, low-dose, safe, and convenient treatment.”
