Prevention of Nausea Associated With Motion Sickness Treatment of Nausea Associated With Motion Sickness | Drug: Scopolamine Transdermal Patch [Transderm Scop] Drug: Scopolamine Drug: Placebo Patch Drug: Placebo Gel | Phase 3 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 320 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | 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. |
Masking: | Triple (Participant, Care Provider, Investigator) |
Masking Description: | Double Blinded |
Primary Purpose: | Treatment |

Estimated Study Start Date : | April 2019 |
Estimated Primary Completion Date : | November 2019 |
Estimated Study Completion Date : | March 2021 |

- Determine the efficacy of DPI-386 nasal gel compared to the TDS patch and placebo nasal gel in the prevention and treatment of nausea associated with motion sickness. [ Time Frame: Through study completion, an average of 1 year ]The efficacy endpoint will be determined by comparing the Motion Sickness Assessment Questionnaire (MSAQ)(scale 1-10) scores over the treatment period across all three treatment arms
- Determine the safety of DPI-386 Nasal Gel compared to the TDS patch and placebo nasal gel with an emphasis on cognitive effects. [ Time Frame: Through study completion, an average of 1 year ]the safety endpoint is the incidence of adverse events.
- Determine the efficacy of DPI-386 Nasal Gel compared to the TDS patch and the placebo nasal gel in severity of nausea. [ Time Frame: Through study completion, an average of 1 year ]Severity of nausea will measured by the Nausea Assessment (VAS)(scale 1-9) over the treatment period.
- Determine the safety of DPI-386 Nasal Gel as compared to the TDS patch and placebo nasal gel in terms of cognition. [ Time Frame: Through study completion, an average of 1 year ]Safety in terms of cognition will be measured by Computer task.
