Nasal Gel Under Military Operational Conditions for the Prevention of Nausea Associated With Motion Sickness

February 13, 2020 updated by: Repurposed Therapeutics, Inc.

A Randomized, Double-Blind, Placebo-Controlled Phase 3 Study of the Safety and Efficacy of DPI-386 Nasal Gel Under Military Operational Conditions for the Prevention of Nausea Associated With Motion Sickness

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will have three arms: DPI-386 nasal gel, placebo nasal gel, and Transderm Scop® (1.5 mg/72 hours; transdermal scopolamine patch [TDS], 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 ships and ships' crews will be used, until the required enrollment is completed. The DPI-386 Nasal Gel and placebo nasal gel arms will be double-blinded, whereas the TDS arm will remain unblinded. Both DPI-386 Nasal Gel and placebo nasal gel will be administered twice daily over the six consecutive Treatment Days. The two daily doses of DPI-386 Nasal Gel or placebo nasal gel will be separated by a minimum of six hours ± 15 minutes, and will occur during the subject's on-duty period. The TDS patch will be administered on Treatment Days 1 and 4.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Efficacy of DPI-386 Nasal Gel
Time Frame: 3 days
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
Time Frame: 24 hours
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.
24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Efficacy of DPI-386 and severe nausea
Time Frame: 3 days
Compare the efficacies of DPI-386 Nasal Gel, TDS patch, and placebo nasal gel in severity of nausea. Respondents specify their degree of nausea by indicating a point along a continuous 100mm 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. Severity of nausea will measured by the Nausea Assessment (Visual Analog Scale) (VAS)) over the treatment period.
3 days
Safety of DPI-386 Nasal Gel in terms of cognition
Time Frame: 24 hours
Compare the safety of DPI-386 Nasal Gel with that of TDS patch and placebo nasal gel in terms of cognition as measured by the Psychomotor Vigilance Tests (PVT). The (PVT) is a neurocognitive assessment that measures alertness and tests sustained attention and reaction time. It was originally developed for sleep studies, and involves simple reaction time testing by requiring the participant to push a button as soon as the stimulus (a light) appears. After a response, the reaction time (in ms) is displayed. The inter-stimulus interval varies from two to 10 seconds, so it is not predictable, and the entire task takes 10 minutes.
