Bioequivalence Study of SKI-O-703 in Healthy Adults Under Fed Conditions

Starting soon · Phase 1

Conditions studied: Bioequivalence Study in Healthy Subjects, Immune Thrombocytopenia (ITP), Rheumatoid Arthritis (RA)

In brief

This is an open-label, randomized, crossover Phase 1 study to evaluate the bioequivalence, pharmacokinetics, and safety of two oral SKI-O-703 drugs (test and reference) in healthy adults under fed conditions. Approximately 48 Korean and Caucasian participants will receive a single oral dose of the test drug and a single oral dose of the reference drug in a randomized sequence, separated by a washout period, with pharmacokinetic sampling and safety assessments performed throughout the study.

This determination must be recorded in the participant's source documents.

• Received an experimental drug within 1 month or within a period less than 10 times the drug's half-life, whichever is longer, before the first dose of the study drug is scheduled. Prior experience of participating in another clinical trial within 6 months before the planned first dose of the study drug.
• Individuals who have dietary habits that may influence the absorption, distribution, metabolism, or excretion of the investigational product or who consume foods known to affect drug metabolism.
• Before the start of the study (first day of administration) those who have donated whole blood or blood components within 8 weeks or within 2 weeks, respectively, or received a blood transfusion within 1 month, or cannot refrain from donating blood from the time of written consent until the end of the trial.
