A questionnaire called the Nausea Vomiting Daily Diary (NV-DD) will be completed once a day, which will be used to collect data for this endpoint. The NV-DD asks participants to record their vomiting frequency in a 24-hour period.

AEs will be coded using the MedDRA coding dictionary. An AE is defined as any untoward medical occurrence in a clinical investigation subject that does not necessarily have causal relationship with treatment. AEs will further be categorized by severity, relationship to study medication, and action taken. All AEs will be presented in data listings for subjects. The Columbia-Suicide Severity Rating Scale (C-SSRS) is a semi-structured clinical interview designed to systematically assess and track suicidal adverse events (behavior and ideation) throughout different settings including clinical trials. Results from the C-SSRS will be listed for each subject. These data will also be summarized for all subjects for suicidal ideation events, suicidal behaviors, and completed suicides.

Vital sign measurements include oral temperature (C), respiratory rate, semi-supine blood pressure (systolic and diastolic) (mmHg) and semi-supine heart rate (bpm). Criteria for identifying vital signs as Potentially Clinically Notable Abnormalities are based on the Guidelines for the Division of Neuropharmacological Drug Products. Data from vital signs will be listed, clinically notable values will be flagged, and other information collected will be listed. Data will also be summarized using mean change from first study visit and proportion of subjects with values outside the normal range, and values that were clinically notable.

Variables include PR (ms), QRS (ms), QTc (ms), and Heart Rate (bpm). Note: ms = millisecond; bpm = beats per minute

Laboratory data will be summarized by presenting the proportions of patients with clinically notable abnormalities as follows: shift tables, first study visit to most extreme post-treatment value, using normal ranges; summary statistics of raw data and change from first study visit values (means, medians, standard deviations, ranges). Criteria for identifying laboratory values as Potentially Clinically Notable Abnormalities are based on the FDA's Guidelines for the Division of Neuropharmacological Drug Products.

Prevention of vomiting measured by Vomiting Assessment (VA) score. The VA is a 1-item questionnaire to objectively measure the incidence of emesis. Participants will indicate whether or not they have vomited.

Safety will be monitored using clinical measures, vital signs, blood chemistry, hematology, urology, and ECGs.

A daily symptom diary asking patients to rate their nausea on a Likert scale from 0-5 (0=none, 5= very severe).

Reduction of worst itch in atopic dermatitis as measured by Numerical Rating Scale (NRS). Worst Itch NRS is an assessment tool that is used to report the maximum intensity of participant's itch during a 24-hour recall period. Participants were asked the following question: Please rate the itching severity that describes your worst level of itching in the past 24 hours \[0=No Itch, 10=Worst Itch Imaginable\].

As measured by the Motion Sickness Severity Scale (MSSS) (NRS 0-6); Lower score indicates improvement

Defined as subjects ever vomited (MSSS=6) or terminated early due to severity during the vehicle travel. As measured by the Motion Sickness Severity Scale (NRS 0-6).

Responses were measured on a 100-mm Visual Analogue Scale (VAS), where the left endpoint was marked "no itch" (0 mm) and in the right endpoint was marked "worst imaginable itch" (100 mm).
