The Prevention and Treatment of Nausea Associated With Motion Sickness

Completed · Phase 3 · Has a placebo group

Conditions studied: Motion Sickness

In brief

This single-site Phase 3 clinical trial is a randomized, double-blind, placebo-controlled study to identify the safety and efficacy of a repeated-dose regimen 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 an ocean going vessel to obtain data in a real world environment. The study will have three arms: DPI-386 nasal gel, placebo nasal gel, and TDS patch (1.5 mg/72 hours), the current standard of care for the treatment of motion sickness. The study will include 100 subjects per arm, for a total of 300 subjects (n=300). Multiple voyages with the same vessel will be used until the required enrollment is completed. A double dummy design will be used to mask the treatment assignment. All subjects will receive both a patch and nasal gel randomized to one of the following three arms: DPI-386 Nasal Gel + placebo patch, placebo nasal gel + placebo patch, and placebo nasal gel + TDS patch.
