Detailed Description
This Phase 3 clinical trial is a randomized, double-blind, placebo-controlled study to identify the safety, efficacy and pharmacokinetics 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 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 34 subjects per arm, for a total of 102 subjects (n=102). 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, or placebo nasal gel + TDS patch.
Treatment Day 1 will be conducted aboard an ocean-going vessel to obtain data in an operationally relevant real world environment immediately followed by Treatment Days 2 and 3 at a clinical site or one of its two satellite locations.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Severity of nausea as measured by the Visual Analog Scale (VAS)
Time Frame: During the 8 hour voyage on Treatment Day 1.
|
VAS - Respondents specify their degree of nausea by indicating a point along a continuous 100 mm line between two end-points; left one is for "No nausea" and the right one for "Very severe nausea".
Scoring is based on the length from left point and a higher score means more severe degree of nausea (Spinks & Wasiak, 2011).
|
During the 8 hour voyage on Treatment Day 1.
|
Severity of motion sickness as measured by the Motion Sickness Assessment Questionnaire (MSAQ) over the treatment period.
Time Frame: During the 8 hour voyage on Treatment Day 1.
|
MSAQ - The MSAQ was designed to measure motion sickness as a multi-dimensional construct, with the understanding that when an individual states they are experiencing motion sickness, it is unlikely a single symptom, but rather a complex set of symptoms, with varying levels of severity.
Sixteen symptoms are listed, with symptoms differentiated along four dimensions: gastrointestinal, central, peripheral, and sopite-related.
Each symptom is scored from 1 to 9 in severity and scores then calculated.
All 16 items were collected from the general public instead of experts, allowing for a more accurate wording of the symptomology experienced by persons outside of physiological sciences.
The MSAQ has been repeatedly validated and is strongly correlated with both the Pensacola Diagnostic index (r = 0.81, p < 0.001) and the Nausea Profile (r = 0.92, p < 0.001).
|
During the 8 hour voyage on Treatment Day 1.

Time Frame: During all three Treatment Days.
