Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This multi-site Phase 3 clinical trial is a randomized, double-blind, placebo-controlled study to identify the safety and efficacy of DPI 386 nasal gel (intranasal scopolamine gel) for the prevention and treatment of nausea associated with motion sickness. The study will be conducted aboard military ships undergoing military operations or aboard commercial boats rented for the study to obtain data in a real world environment. The study will have three arms: DPI-386 nasal gel, placebo nasal gel, and Transderm Scop® (1.0 mg/72 hours; transdermal scopolamine patch \[TDS\], the current standard of care for the treatment of motion sickness). The study will include 120 subjects per arm, for a total of 360 subjects (n=360). A double-dummy design will be used to mask the treatment assignment. All subjects will receive both a patch and nasal gel: DPI-386 Nasal Gel + placebo patch, placebo nasal gel + placebo patch, or TDS patch + placebo nasal gel.
