What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ScopolamineDrug

    Intranasal scopolamine at 0.2 mg or 0.4 mg

  • PlaceboDrug

    Intranasal saline placebo

Study groups in NCT04999449
Study groupRoleWhat they receive
PharmacokineticExperimentalParticipants receive 1 dose of Scopolamine 0.4 mg delivered via a intranasal nebulizer developed by Creare LLC.
Receives: Drug: Scopolamine
ChairExperimentalParticipants receive 1 dose of Scopolamine 0.2 mg, 1 dose of Scopolamine 0.4 mg, and 1 dose of placebo saline delivered via the Creare LLC intranasal nebulizer. These dosages are all 1 week apart and the order is randomized.
Receives: Drug: Scopolamine; Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to maximal concentration for scopolamine after intranasal administration (Tmax)

    Plasma scopolamine concentrations will be measured using an liquid chromatography-mass spectrometry (LC- MS) assay. Tmax is measured in minutes to reach the maximum concentration.

    Measured: Baseline, 180 minutes

  2. Side effects of intranasal scopolamine, as measured through a questionnaire with a subjective rating scale

    A questionnaire will be administered asking about the participant's side effect profile after taking intranasal scopolamine. The questionnaire will have a subjective rating scale of 0-10 on the potential scopolamine side effects expected

    Measured: 180 minutes

Secondary outcomes (1)
  1. Effectiveness in reducing motion sickness as measured by duration of chair ride.

    The degree of motion sickness will be assessed by measuring the total number of minutes the subject rides in the chair before stopping

    Measured: Baseline, end of chair ride (maximum of 20 minutes)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Scopolamine in people with Scopolamine and Motion Sickness, run by Dartmouth-Hitchcock Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to maximal concentration for scopolamine after intranasal administration (Tmax) (time frame: Baseline, 180 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2025.
