NCT04272255

Brief Summary

This multi-site Phase 3 clinical trial is a randomized, double-blind, placebo-controlled and open label active-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 motion sickness. The study will be conducted aboard Navy fleet or Marine ships undergoing military operations to obtain data in an operationally relevant real world environment.

Outcome Measures

Primary Outcomes (2)

  • Efficacy of DPI-386 Nasal Gel

    Compare the efficacy of DPI-386 Nasal Gel (0.2 mg scopolamine HBr per dose, maximum of two doses per day, for a maximum of six doses over three consecutive days) with that of 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) scores over the treatment period across all three treatment arm. 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 hysiological sciences.

    3 days

  • Safety of DPI-386 Nasal Gel in terms of cognitive effects

    Compare the safety of DPI-386 Nasal Gel with that of the TDS patch and placebo nasal gel, with an emphasis on cognitive effects by incidence of treatment related adverse events.

Study Arms (3)

DPI-386 nasal gel

ACTIVE COMPARATOR

DPI-386 Nasal Gel is formulated to contain 0.2 mg scopolamine HBr per 0.1 g dose, with each dose therefore described as "0.2 mg / 0.1 g"

Drug: scopolamine HBr

PLACEBO COMPARATOR

Placebo nasal gel product is the same but does not contain scopolamine HBr

Drug: scopolamine HBr

Transderm Scop®

EXPERIMENTAL

TDS patch delivers 1.5 mg of scopolamine over a 72-hour period. TDS arm will apply two TDS patches over the six treatment days.
