Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male or female participants aged between 18 and 60 years of age, inclusive at the time of signing the informed consent document.
2. Body weight ≥50 kg and body mass index (BMI) within the range of 18 to 32 kg/m2 inclusive at screening.
3. Woman of childbearing potential (WOCBP) or fertile male participants must agree to use an acceptable method of contraception from the start of Screening until 90 days (male participants) or 60 days (female participants) after the final study visit.
4. WOCBP must have a negative serum pregnancy test at screening and a negative urine pregnancy test prior to administration of the first dose of study intervention (including domperidone) and be willing to have additional pregnancy tests, as required, throughout the study.
5. Participants must be in good general health, as demonstrated at screening and prior to first administration of any study intervention (including domperidone) by the absence of clinically significant (in the opinion of the Investigator) abnormalities based on a medical evaluation including review of medical history, physical examination, safety laboratory tests, vital signs, 12-lead ECG monitoring.

Note: It is the responsibility of the Investigator to assess the clinical significance of any abnormality/ies; however, consultation with the MM may be warranted.
6. Normal vital signs after ≥5 min resting in supine position:

1. ≥90 mmHg and ≤160 mmHg systolic blood pressure (SBP)
2. ≥50 mmHg and ≤95 mmHg diastolic blood pressure (DBP)
3. ≥ 45 bpm and ≤100 bpm heart rate (HR)
4. Body temperature (tympanic) ≥35.5°C and ≤37.7°C
7. No clinically significant changes and/or associated symptoms considered related to orthostatic hypotension when measuring blood pressure (BP) and pulse rate (PR) within 2 min of standing from a supine position.
8. Triplicate 12-lead ECG, taken after ≥5 min in a supine, position, with a QT interval corrected using the Fridericia method (QTcF) ≤ 450 msec for males and ≤ 470 msec for females, PR interval ≤ 220 msec or QRS duration ≤ 120 msec or history of long QT syndrome and no clinically significant abnormalities as judged by the Investigator (or qualified designee).
9. Willing and able to be confined at the CRU for the study period and adhere to overall study visit schedule, procedures and other protocol requirements, as assessed by the Investigator (or qualified designee).
10. Understands and voluntarily signs an informed consent document prior to any study related assessments/procedures being conducted.

Exclusion Criteria

1. Any significant medical condition, physical or psychiatric illness or history of depression that could, in the Investigator's (or qualified designee) opinion, compromise the participant's safety or interfere with the completion of this study.
2. History of clinically significant CNS, cardiac, pulmonary, metabolic, renal, hepatic, or gastrointestinal (GI) conditions including gastric bypass or other weight loss surgical procedure.
3. Any condition including the presence of laboratory abnormalities, which according to the Investigator (or qualified designee), places the participant at unacceptable risk if they were to participate in the study or may confound the ability to interpret data from the study. This includes the presence of uncontrolled current illness (e.g., an infection), a viral infection, seasonal allergy, or concurrent skin rash.
4. Any nasal condition, including nasal congestion, physical blockage of either nostril, deviated septum, structural or anatomical nasal conditions or nasal surgery in the last 6 months. Use of topical nasal medications (e.g., acute or chronic use of prescription or over the counter nasal sprays) that may affect the administration or absorption of the study drug.

These laboratory tests may be repeated once if they are abnormal on first screening, and if there is a medical reason to believe the results may be inaccurate. If the repeat test is within the normal range, the participant may be included in the study only if the Investigator (or qualified designee) considers that the previous finding will not compromise the participant's safety and will not interfere with the interpretation of safety data.
8. A positive drug or alcohol screen. A positive drug or alcohol screen test result may be verified by re-testing at the discretion of the Investigator (or qualified designee), with up to 1 false positive result permitted.
9. History of regular alcohol consumption within 6 months of screening defined as an average weekly intake of \>21 units. One unit is equivalent to 10 g of alcohol and the following can be used as a guide: a half-pint (\~240 mL) of beer, 1 glass (125 mL) of wine or 1 (30 mL) measure of spirits.
10. The participant is unwilling to abstain from alcohol consumption from 24 h prior to treatment with any study intervention (including domperidone) and until discharge from the CRU, and for 24 h prior to all other outpatient visits to the CRU.
11. The participant is pregnant or planning to become pregnant within 90 days of the study or is breastfeeding.
12. Major surgery within 4 weeks of screening that could interfere with, or for which the treatment might interfere with, the conduct of the study, or that would pose an unacceptable risk to the participant in the opinion of the Investigator (or qualified designee).
13. Use of tobacco or nicotine products exceeding 5 cigarettes (or equivalent) per week in any form within 30 days prior to treatment with any study intervention (including domperidone), or unwillingness to refrain from smoking, vaping, or using any nicotine products for at least 48 h prior to dosing with any study intervention (including domperidone), the confinement period, and any follow up visits.
