Description of intervention(s) / exposure
Accro Bioscience is developing AC-201, a potent and selective oral small molecule inhibitor of tyrosinekinase 2 (TYK2) and JAK1, indicated for treatment of the moderate-to-severe plaque psoriasis.
Investigational Product(IP):AC-201
Dose:50 mg
Dosage Form:Tablet
Mode of Administration:Oral
An open panel of 12 subjects will receive single dose (50 mg) of AC-201 under both fed and fasted conditions in a two-period crossover study.
In the study,6 subjects will receive a single administration of AC-201 under fasted condition in period 1,and receive another administration of AC-201 after a high-fat meal in period 2, after a washing out period.For the other 6 subjects, the administration of AC-201 in period 1 will be carried out under a fed condition,the administration of AC-201 in period 2 will be carried out at fasted condition.
The subjects will have a total of 7 overnight stays (admission on Day -1 until Day 7).
Regarding the high-fat meal, the FDA high-fat breakfast will be provided to the subjects 30min prior to dosing.
A high-fat(approximately 50 percent of total caloric content of the meal) and high-calorie(approximately 800 to 1000 calories) meal will provide to the subject 30min prior to dosing.This test meal should derive approximatly 150,250 and 500-600 calories from protein,carbihydrate,and fat,respectively.
The participants are dosed at the site, they will receive study treatment directly from the Investigator or designee, under medical supervision. lmmediately after dose administration,visual,inspection of the mouth and hands will be performed for each subject. The date and time of eachdose administered will be recorded in the source documents. The dose of study treatment and study participant identification will be confirmed at the time of dosing by a member of the study site staff otherthan the person administering the study treatment.

Summary
Brief summary
This is open label, cross over study to evaluate the safety, tolerabitity, pharmacokinetics (PK) food effects of AC-201 following oral single ascending dose administration in healthy male and female
participants. The impact of food (high-fat breakfast) on the rate and extent of absorption will be evaluated.Food Effect (FE)study enrolling 1 cohort of subjects (Part 2) to receive AC-201 under both fasted and fed conditions for investigating the effect of food.
In this part of the study the dose given in Fed Period will be administered 30 minutes after starting a high-fat breakfast.
A high-fat (approximately 50 percent of total caloric content of the meal) and high-calorie (approximately 800 to 1000 calories) meal will provide to the subject 30 min prior to dosing. This test meal should derive approximately 150.250,and 500-600 calories from protein, carbohydrate, and fat, respectively.
