Description of intervention(s) / exposure
Treatment: Drugs - SMP-100

Experimental: Treatment A: SMP-100 dissolved in water administered under fasting conditions - 12 subjects,For Treatment A, SMP-100 will be dissolved in a total of 240 mL of water and administered orally to each subjects, and a hand and mouth check will be performed to ensure consumption of the medication. Subjects will be required not to wear dentures or mouth piercing at the time of dosing. No food will be allowed from at least 10 hours before dosing until at least 4 hours post-dose.

Experimental: Treatment B: SMP-100 tablets administered under fasting conditions - 12 subjects,For Treatment B, SMP-100 tablets will be administered to each subject with 240 mL of water and a hand and mouth check will be performed to ensure consumption of the medication. The dosing procedure must be completed within 2 minutes. In the event that subjects cannot swallow all tablets with 240 mL of water, additional water may be allowed up to a maximum total volume of 400 mL. No food will be allowed from at least 10 hours before dosing until at least 4 hours post-dose.

Experimental: Treatment C: SMP-100 tablets administered under fed conditions - 12 subjects,For Treatment C, SMP-100 tablets will be administered to each subject with 240 mL of water and a hand and mouth check will be performed to ensure consumption of the medication. The dosing procedure must be completed within 2 minutes. In the event that subjects cannot swallow all tablets with 240 mL of water, additional water may be allowed up to a maximum total volume of 400 mL.
After a supervised fast of at least 10 hours, subjects will be served a high-fat, high-calorie meal of approximately 800 to 1000 calories (approximately 50% of total caloric content of the meal derived from fat). This test meal should derive approximately 150, 250, and 500-600 calories from protein, carbohydrate, and fat, respectively. Subjects should start the meal approximately 30 minutes prior to drug administration. Subjects will be required to completely eat the meal in 30 minutes or less. No food will be allowed until at least 4 hours post-dose.


Treatment: Drugs: SMP-100
In each period, subjects will receive a single dose of SMP-100 on Day 1 (Period 1), Day 4 (Period 2), and Day 7 (Period 3), under fasting or fed conditions, followed by 48 hours of PK and safety assessments.
