This is a randomized, single-center, single-blind, placebo-controlled, dose-escalation Phase 1 clinical trial designed to evaluate the safety, tolerability, pharmacokinetic, and pharmacodynamic characteristics of multiple intravenous (IV) infusions of KINE-101 in healthy adult volunteers.
The study includes three sequential cohorts with a total of 24 subjects (8 subjects per cohort; 6 assigned to KINE-101 and 2 to placebo). Subjects in the treatment groups receive KINE-101 once daily for 7 consecutive days at doses corresponding to their assigned cohort (Cohort 1: 120 mg, Cohort 2: 240 mg, Cohort 3: 360 mg). Subjects in the placebo group receive 0.9% saline under identical conditions. All subjects are admitted on Day -1, receive daily dosing from Day 1 through Day 7, and are discharged on Day 9 after completion of safety monitoring. Follow-up visits are conducted on Days 14, 21, 28, and 35. Dose escalation proceeds sequentially from the lowest-dose cohort (Cohort 1) to the highest-dose cohort (Cohort 3). Safety and tolerability data collected through Day 35 in each preceding cohort are reviewed before initiating dosing in the next higher-dose cohort.
