Enrollment: 56
Healthy volunteers: yes

Brief summary:
A randomized, double-blind, placebo-controlled single and multiple dosing, dose escalation phase I clinical trial to investigate the safety/tolerability and pharmacokinetics of HY209 gel after transdermal administration in healthy male volunteers as a possible treatment option for atopic dermatitis

Detailed description:
A composition containing G Protein Coupled Receptor 19(GPCR19) agonist HY209 and a derivative thereof is found to have a considerable effect in the treatment of atopic dermatitis and is proposed as a pharmaceutical ingredient for prevention, treatment and improvement of atopic dermatitis. The GPCR19 agonist, HY209, is superior to conventional steroid ointment and immunosuppressant ointment in the treatment and improvement of allergic dermatitis. It directly reduces the amount of serum immunoglobulin E, which is a major factor of allergic dermatitis, It increases the T helper type 1(TH1) cytokines that alleviate allergic dermatitis pathologies, reduces the T helper type 2(TH2) cytokines that aggravate allergic dermatitis pathologies, and reduces the infiltration of mast cells, eosinophils and neutrophils into the dermal cells. Thus it can be utilized as a therapeutic drug composition for atopic dermatitis.

Arms:
arm 1: single dose of HY209 0.05% gel or single dose of placebo arm 2: single dose of HY209 0.1% gel or single dose of placebo arm 3: single dose of HY209 0.3% gel or single dose of placebo arm 4: single dose of HY209 0.5% gel or single dose of placebo arm 5: multiple dose of HY209 0.1% gel or multiple dose of placebo arm 6: multiple dose of HY209 0.3% gel or multiple dose of placebo arm 7: multiple dose of HY209 0.5% gel or multiple dose of placebo

Interventions: intervention 1: HY209
Intervention descriptions: intervention 1: 6 subjects will be assigned to drug (HY209) and 2 subjects will be assigned to placebo.

Target disease 
Atopic Dermatitis 
Purpose 
The purpose of this study is to evaluate the safety, tolerability and 
pharmacokinetics of HY209 gel as a possible treatment option for atopic 
dermatitis. 
Study Design 
Randomized, double-blind, placebo-controlled (single and multiple 
dosing), dose escalation phase I clinical trial 
Study Method 
(1) Cohort A Single dosing 
Four groups (HY209 0.05%, 0.1%, 0.3%, 0.5%) of subjects, each group 
consisting of control 6 and placebo 2 will be randomly selected. The trial 
drug or placebo will be applied on the back of each subject. Subjects will 
be released after present tests and blood drawing. 
 
 
(2) Cohort B Multiple dosing 
Three groups (HY209 0.05%, 0.1%, 0.3%) of subjects, each group 
consisting of control 6 and placebo 2 will be randomly selected. The trial 
drug or placebo will be applied on the back of each subject at once a day 
for 28 days. Subjects will visit the clinical research center to be tested 
and have their blood drawn,
