Brief summary

This first in human, single-center, randomized, placebo-controlled, double blind, sequential group Phase 1 study in healthy subjects will be conducted to evaluate the safety, tolerability, PK, and PD following the escalation of single and multiple doses of KM-819. The study will consist of 2 parts. In Part A, up to 5 cohorts of young adult male subjects, and 1 single dose cohort of elderly male or post menopausal female subjects will receive escalating single doses of KM-819. In Part B, up to 4 cohorts of healthy young adult male subjects and 1 multiple dose cohort of elderly male or post menopausal female subjects will receive escalating multiple doses of KM-819. Part B will be conducted after completion of all cohorts of young adult male subjects in Part A. Dose escalation to the next level will be determined using safety, tolerability, and PK data of the previous cohort. Part A, Single Ascending Dose (SAD) Up to 40 healthy young adult male subjects and 8 healthy elderly male or post menopausal female subjects will be enrolled and randomized to receive either KM-819 or placebo. Each of the 5 dose escalation cohorts consists of 8 healthy young adult male subjects; 6 subjects will receive 10, 30, 100, 200, or 400 mg of KM-819 and 2 subjects will receive placebo. In each single dose cohort, dosing of subjects will be sentinel, i.e., 2 subjects will be dosed on the first day (1 subject will receive active treatment and 1 subject will receive placebo) and the remaining 6 subjects will be dosed at least 24 hours after the first 2 subjects. Cohorts will be dosed sequentially with escalating doses. Eight elderly male or post-menopausal female subjects will be enrolled into an additional cohort; 6 subjects will receive 200 mg KM-819 and 2 subjects will receive placebo. Part A consists of a Screening period of up to 28 days, and a 3 day Confinement period when subjects are hospitalized for study activities. Subjects are required to return for outpatient visits on Day 4, 7 and for the Follow up Visit on Day 14. Part B, Multiple Ascending Dose (MAD) Up to 32 healthy young adult male subjects and 8 healthy elderly male or post menopausal female subjects will be enrolled and randomized to receive either KM-819 or placebo. Each of the 4 dose escalation cohorts consists of 8 healthy young adult male subjects; 6 subjects will receive 30, 100, 200, or 400 mg of KM-819 once a day (QD) for 7 days and 2 subjects will receive placebo. Cohorts will be dosed sequentially with escalating doses. Eight elderly male or post-menopausal female subjects will be enrolled into an additional cohort; 6 subjects will receive 200 mg KM-819 QD for 7 days and 2 subjects will receive placebo.

Change From Baseline for Bond and Lader Visual Analogue Scale (VAS)

The Bond-Lader Visual Analogue Scales (VAS) will be analyzed using 3 factor scores: alertness, contentedness, and calmness. Participants were asked to indicate on the VAS scale ranging from 0 to 100 mm about how they felt at the moment the scale was administered. Baseline is defined as the last available recording prior to dosing on Day 1. 1. Alertness (Range 0 to 100, the higher scores indicated more alertness) 2. Mood (Range 0 to 100, where higher scores indicated elevated mood) 3. Calmness (Range 0 to 100, where higher scores indicated more calmness).

Time frame: At Day 1 (3 hours post dose), Day2, Day 3, Day 4, and Day 8.

Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV)

The K-WAIS-IV consists of an assessment of the cognitive ability using a core battery of 10 unique subtests (Block Design, Similarities, Digit Span, Matrix Reasoning, Vocabulary, Arithmetic, Symbol Search, Visual Puzzles, Information, and Coding) that focus on four specific domains of intelligence: verbal comprehension, perceptual reasoning, working memory, and processing speed. The Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index (standard scores: mean=100, standard deviation=15) that are all based on a number of core and supplemental subtests (scaled scores: mean=15, standard deviation=3) that provide pertinent clinical information and flexibility in implementation. The higher values represent a better outcome.

Time frame: Part A: Day 1; Part B: Day 7
