- the absence of clinically significant history of irritable bowel syndrome (IBS) of any type.
- the absence of current or history of ischemic colitis.
- Females of childbearing potential who are sexually active with a non-sterile male partner (sterile male partners are defined as men vasectomized since at least 6 months) must be willing to use one of the following acceptable contraceptive methods throughout the study and for 30 days after (the last) study drug administration:
- simultaneous use of intra-uterine contraceptive device placed at least 4 weeks prior to (the first) study drug administration, and condom for the male partner;

- simultaneous use of a male condom and, for the female partner, a diaphragm.
- Male subjects (including men who have had a vasectomy) with a pregnant or same-sex partner must agree to use a condom from the first study drug administration until at least 90 days after the last study drug administration.
- Male subjects must be willing not to donate sperm until 90 days following the last study drug administration.
- Willing to take off dentures or mouth piercing at the time of dosing.
- Capable of consent.
Exclusion
- Any clinically significant abnormality at physical examination.
- Any clinically significant abnormal laboratory test results or positive test for hepatitis B, hepatitis C, or HIV found during medical screening.
- Positive urine drug screen, alcohol breath test, or urine cotinine test at screening. A repeat test can be conducted at screening or Day -1 at the discretion of the Principal Investigator or delegate.
- History of allergic reactions to SMP-100 or other related drugs, or to any excipient in the formulation.
- History of hypersensitivity to 5-HT3 receptor antagonists or agonists.
- Positive serum pregnancy test at screening.
- Clinically significant ECG abnormalities (QTcF \>450 ms for males and QTcF \>460 ms for females).
- Clinically significant vital sign abnormalities (systolic blood pressure lower than 90 or over 159 mmHg, diastolic blood pressure lower than 50 or over 100 mmHg, or heart rate less than 50 or over 100 bpm) at screening. Repeat test can be conducted at screening or Day -1 at the discretion of the Principal Investigator or delegate.
- Clinically significant orthostatic vital sign abnormalities such as decrease in systolic blood pressure of 20 mmHg or higher, decrease in diastolic blood pressure of 10 mmHg or higher, or increase in heart rate of 30 bpm or higher within 3 minutes after passing from a supine to a standing position. Repeat test can be conducted at screening or Day -1 at the discretion of the principal investigator or delegate.
- History of significant alcohol abuse within 1 year prior to screening or regular use of alcohol within 6 months prior to the screening visit (more than 14 units of alcohol per week \[1 unit = 150 mL of wine, 375 mL of mid strength beer, or 30 mL of 40% alcohol\]).
- History of significant drug abuse within 1 year prior to screening or use of drugs such as marijuana within 3 months prior to the screening visit or drugs such as cocaine, phencyclidine \[PCP\], crack, opioid derivatives including heroin, and amphetamine derivatives within 1 year prior to screening.
- Participation in a clinical research study involving the administration of an investigational drug or device within 30 days prior to the first dosing.
- Administration of a biological product in the context of a clinical research study within 90 days prior to the first dosing.
- Use of medications for the timeframes specified below, with the exception of medications exempted by the Investigator on a case-by-case basis because they are judged unlikely to affect the PK profile of the study drug or subject safety (e.g., topical drug products without significant systemic absorption):
- prescription medications within 14 days prior to the first dosing;
- over-the-counter products and natural health products (including herbal remedies homeopathic and traditional medicines, probiotics, food supplements such as vitamins, minerals, amino acids, essential fatty acids, and protein supplements used in sports) within 14 days prior to the first dosing, with the exception of the occasional use of paracetamol (up to 2 g daily);
- any prescription or over-the-counter medication or natural health products used for the treatment of irregular bowel transit (e.g. diarrhea, constipation) within 4 weeks prior to the first dosing;
- depot injection or implant of any drug within 3 months prior to the first dosing;
- use of any drugs known to induce or inhibit hepatic metabolism (including St. John's Wort \[hypericin\]) within 14 days prior to the first dosing.
- Donation of plasma within 7 days prior to dosing. Donation or loss of blood (excluding volume drawn at screening) of 50 mL to 499 mL of blood within 30 days, or more than 499 mL within 56 days prior to the first dosing.
- Presence of:
- orthodontic braces or orthodontic retention wires, or
- any physical findings in the mouth or tongue that would be likely to interfere with successful completion of the dosing procedure.
