NCT05886660

Brief Summary

The primary specific aim is to evaluate the use of intranasal scopolamine gel and sensory augmentation as an integrated countermeasure to mitigate motion sickness and enhance sensorimotor performance. The proposed intranasal scopolamine gel formulation (Defender Pharmaceuticals, Inc.) offers a safe non-invasive method to self-administer with a rapid onset of action. This study involves a comparison of motion sickness outcome measures when administering intranasal scopolamine gel versus placebo (Aim 1a), and then when administering intranasal scopolamine gel versus placebo with a sensory augmentation belt (Aim 1b).

Outcome Measures

Primary Outcomes (1)

  • Motion sickness (MS) symptom severity using Pensacola Diagnostic Index (PDI) scale

    The PDI scale ranges from 0 to 16 with higher numbers reflecting greater symptom severity (in this study a PDI score of 8 will be used as a motion sickness (MS) endpoint). During each session, the primary motion sickness symptoms will be recorded every minute during the capsule wave motion stimulation through the MS endpoint (PDI score ≥ 8 points) up to 45 min total.

    45 minutes

Secondary Outcomes (4)

  • Motion sickness symptom severity using a Subjective Discomfort Rating (SDR)

    45 minutes

  • Time to MS endpoint (based on PDI score of 8 points)

    45 minutes

  • Performance measures: response time

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects should be minimally susceptible to provocative motion as evidenced by at least two responses on the Motion Sickness Susceptibility Questionnaire of "Sometimes" or "Frequently."
  • No participants should have neurologic, vestibular or autonomic disorders, or medical conditions that could be worsened by scopolamine (narrow-angle glaucoma or urinary retention
  • Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) negative test, confirmed by Food and Drug Administration (FDA) authorized COVID-19 test \< 7 days prior to study drug administration or no COVID 19 symptoms up to 10 days prior to study drug administration.

You may not qualify if:

  • Subjects will be excluded if they are taking other drugs that are capable of causing CNS effects such as antihistamines, tricyclic antidepressants, and muscle relaxants or have hypersensitivity to scopolamine or other belladonna alkaloids or to any ingredient or component in the formulation or delivery system.
  • Pregnant women are excluded from participation. Women of child-bearing potential will be offered a pregnancy screening test and excluded with a positive test.
