(Nasdaq: SPRY), a biopharmaceutical company dedicated to empowering patients and their caregivers to better protect against severe allergic reactions that can lead to anaphylaxis, today announced the appointment of Donn Casale as President, effective June 1, 2026. Richard Lowenthal will continue to lead ARS Pharma as Chief Executive Officer. Mr. Casale is a 25-year biopharmaceutical commercial leader with extensive experience scaling innovative products in large consumer-driven healthcare markets, including categories where patients seek therapies that help reduce the risk of future serious medical events. As President, Mr. Casale will oversee global commercial operations and growth infrastructure as ARS Pharma prepares for its next phase of expansion, including advancement into chronic spontaneous urticaria (CSU). He will partner closely with the executive leadership team to help drive the company’s next phase of commercial and organizational growth. “We are very pleased to welcome Donn to the ARS team, where he will play a key role in leading our commercial strategy for neffy® (epinephrine nasal spray) and accelerating adoption and sales growth,” said Richard Lowenthal, Co-founder and CEO of ARS Pharma. “Donn has built and led commercial organizations that successfully scaled innovative products in large, patient-driven markets similar to our own. His expertise in retail channel execution and payor access strategy will help further expand patient access and accelerate adoption of neffy, while also preparing ARS Pharma for its next phase of growth, including expansion into CSU. We look forward to the strategic perspective and leadership he will bring as we continue expanding access to lifesaving treatments for patients at risk of severe Type I allergic reactions.” Mr. Casale most recently served as Chief Commercial Officer at Dynavax Technologies, where he built the U.S. commercial infrastructure and helped scale the hepatitis B vaccine HEPLISAV-B® from launch to more than $300 million in annualized revenue and over 50 percent U.S. market share. He engineered a transformative commercial strategy and innovative retail pharmacy model that helped position HEPLISAV-B for significant commercial growth prior to Sanofi’s $2.2 billion acquisition of Dynavax. Prior to Dynavax, Mr. Casale held marketing and commercial operations leadership roles at Depomed (now Assertio Therapeutics) and spent 14 years at Merck in progressive leadership roles across the U.S. vaccines business, spanning sales leadership and commercial strategy. Mr. Casale holds a B.A. in Political Science from California Polytechnic State University, San Luis Obispo. “As the first and only needle-free, easy-to-carry epinephrine nasal spray approved in the U.S., neffy has fundamentally changed what is possible in the treatment of severe allergic reactions,” said Mr. Casale. “I believe we have a profound responsibility to increase awareness of the critical need for epinephrine and to serve as a tireless advocate for patients and caregivers. neffy represents a compelling opportunity to redefine preparedness and access in severe allergic reactions, and I look forward to helping drive ARS Pharma’s next phase of growth.” About ARS Pharmaceuticals, Inc.
