Combination of Intranasal Scopolamine and Sensory Augmentation to Mitigate G-transition Induced Motion Sickness and Enhance Sensorimotor Performance

Description

The primary specific aim of this Field Test aim is to evaluate the feasibility and efficacy of administering the intranasal scopolamine gel in operational field settings using both astronaut and ground-control subjects that are exposed to provocative motion as part of their assigned duties. For the ground-control subjects, these may include motion simulations (e.g., centrifuge), parabolic flights and/or Orion capsule recovery operations. Astronaut participants may choose to test Inscop during provocative preflight training exercises (e.g., centrifugation), and can choose to take the medication prophylactically to prevent symptoms or after symptom onset to treat motion sickness during the launch and/or landing mission phases. Both ground-control and astronaut participants will be required to test the medication during a training session to monitor for adverse side effects. Participants in the field test aim will complete short debrief questionnaires to capture motion sickness symptoms, side effects, and feasibility comments. The investigators will also include field "control" subjects who did not take (INSCOP) to comment on what countermeasures subjects used and their effectiveness. The investigators will be recruiting astronaut participants from free-flier missions (e.g., SpaceX Polaris Dawn), Private Astronaut Missions (e.g., Axiom), and standard missions to the International Space Station.

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.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Subjects will involve astronauts assigned to spaceflight missions or test personnel assigned to operational activities that involve provocative motion (e.g., simulations or parabolic flights).
  • 2. No participants should have no neurologic, vestibular or autonomic disorders, or medical conditions that could be worsened by scopolamine (narrow-angle glaucoma or urinary retention)
  • 3. 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.
  • 1. 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.
  • 2. Pregnant women are excluded from participation. Women of child-bearing potential will be offered a pregnancy screening test and excluded with a positive test.
