NCT03920644

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 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.

    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

    Through study completion, an average of 1 year

  • Determine the safety of DPI-386 Nasal Gel compared to the TDS patch and placebo nasal gel with an emphasis on cognitive effects.

    the safety endpoint is the incidence of adverse events.

    Through study completion, an average of 1 year

Secondary Outcomes (2)

  • Determine the efficacy of DPI-386 Nasal Gel compared to the TDS patch and the placebo nasal gel in severity of nausea.

    Through study completion, an average of 1 year

  • Determine the safety of DPI-386 Nasal Gel as compared to the TDS patch and placebo nasal gel in terms of cognition.

    Through study completion, an average of 1 year

  • \. Ability to take intranasal medication and willingness to adhere to the study schedule and time constraints.
  • \. For females of child-bearing potential: willingness to provide a urine sample for the hCG pregnancy test during the Screening Visit and each day of the Treatment Period. Test must be negative or the subject will be excluded from the study. Note: Women of non-childbearing potential are defined as those who are non-surgically sterile (i.e., without menses for at least 12 consecutive months) or surgically sterile (i.e., those who underwent a hysterectomy with or without oophorectomy, fallopian tube ligation, and endometrial ablation).
