Defender Pharmaceuticals Receives Complete Response Letter from the U.S. Food and Drug Administration for its Intranasal Scopolamine (DPI-386) New Drug Application for the Prevention of Nausea and Vomiting Induced by Motion in Adults

ST. LOUIS, MO—(BUSINESS WIRE)—Jan. 30, 2024—Defender Pharmaceuticals, Inc. (the “Company” or “Defender”), a privately held life sciences company based in St. Louis, today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) in response to the Company’s New Drug Application (NDA) for intranasal scopolamine (DPI-386) for the prevention of nausea and vomiting induced by motion in adults.

“Following our review of the CRL, we plan on scheduling a formal meeting with the FDA to fully understand the issues raised in the CRL so we can develop and implement a comprehensive action plan,” said Barry I. Feinberg, M.D., President & CEO of Defender Pharmaceuticals. “We remain confident that our intranasal scopolamine is a safe and effective therapy for the prevention of motion sickness, and we will work closely with the FDA to ensure that we can bring this innovative new product to the market.”

About intranasal scopolamine (DPI-386) Development Program
Defender has worked with the United States Naval Medical Research Unit (NAMRU-D) and the National Aeronautics and Space Administration (NASA) on its intranasal scopolamine development program that is focused on specific military personnel and astronauts.

To date, more than 1,300 patients have participated in Defender clinical studies, including over 500 participants in the DPI-386-MS-33 study. Given the successful outcome of DPI-386-MS-33, Defender has submitted a New Drug Application (NDA) to the Food and Drug Administration (FDA) for DPI-386 Nasal Gel for the prevention of nausea and vomiting induced by motion in adults.

Defender is also developing intranasal formulations designed to treat a wide variety of indications. We believe these new products have the potential to help safeguard health across civilian and military populations.

About Motion Related Discomfort
Certain motions cause discomfort in individuals while engaged in a variety of leisure or travel related activities. Most forms of travel, whether on land, in the air, or on the water, can trigger symptoms such as nausea and vomiting (example: flying, boating/fishing, car, bus, and train). Symptoms induced by motion can also have a detrimental impact on the ability of various military personnel and astronauts to perform assigned duties, potentially impacting readiness and negatively impacting resources. Motion related discomfort is a common and transient response to unfamiliar or unnatural motion or contradictory spatial sensory information, resulting in decrements to performance of tasks, pallor, cold sweating, nausea and vomiting. Prolonged exposure to certain motions may induce sopite-related symptoms such as loss of drive and concentration, drowsiness, sleepiness, apathy, depression, and a feeling of impending doom.
