简要总结
The study is a Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Dose Escalation Study in Healthy Male Subjects with Androgenetic Alopecia to Evaluate the Safety, Tolerability and Pharmacokinetics of KX-826 Following Topical Single Ascending Dose Administration
详细描述
A total of 40 subjects will be evaluated with 32 subjects randomized to receive active drug and 8 subjects randomized to receive placebo in a double-blind fashion (ten subjects in each dose cohort with two subjects randomized to placebo for total of four dose cohorts).Subjects were to be assigned to 1 of the 4 dose levels, 3 mg. 12 mg, 48 mg and 96 mg of KX-826 or placebo to match the active product, administered as a topical application.

干预措施: Placebo (Other)
结局指标
主要结局
Incidence of treatment-emergent adverse events (TEAE) by skin irritation assessments
时间窗: 3 days
Skin irritation assessments will be performed during the treatment period. The dermal response score will be based on a visual irritation scale (0-7) that rates the degree of erythema, edema and other signs of cutaneous irritation.
Incidence of treatment-emergent adverse events (TEAE) by ECG assessment
时间窗: 3 days
12-lead ECG
Incidence of study drug related TEAEs
时间窗: 3 days
incidence of study drug related TEAEs (possibly, probably or definitely)
Incidence of treatment-emergent adverse events (TEAE) by vital signs measurements
时间窗: 3 days
vital signs (including blood pressure, pulse rate, respiratory rate and oral temperatures)
Incidence of treatment-emergent adverse events (TEAE) by clinical lab tests
时间窗: 3 days
hematology (hemoglobin, hematocrit, platelet count, RBC count, WBC count, with differential), blood chemistry (BUN, creatinine, total bilirubin, alkaline phosphatase, AST, ALT, GGT, LDH, glucose, albumin, total protein, bicarbonate, phosphate, sodium, potassium, chloride, calcium, total cholesterol, uric acid) and urinalysis (pH, specific gravity, protein, glucose, ketones, bilirubin, blood, nitrites, leukocytes, urobilinogen, microscopic urine analysis on abnormal findings)
