About

This is a first-in-human study in health volunteers. The purpose is the local tolerability and systemic safety of Hemay808, which is an ointment made of a novel small molecule Hemay028. The safety and systemic pharmacokinetics (PK) of Hemay028 will be evaluated following topical application of Hemay808 to healthy volunteers.

Full description

There are two pre-test groups. Group1 use Hemay808 and placebo on sensitive areas. Group2 will only topical use Hemay808 on 5%BSA.

After 2 pre-test group, 4 formal testing groups will start. 1% Hemay808 apply to 25%BSA; 3% Hemay808 apply to 25%BSA; 3% Hemay808 apply to 55%BSA; 7% Hemay808 apply to 25%BSA. First a single doses then wash-out for three days, after that subjects will applicant twice daily for 7 days to assess the local skin tolerability, and systemic PK of these treatments.

Approximately 42 healthy adult volunteers will be enrolled in this study with 8- 10 volunteers each cohort.

Enrollment: 42 patients

Sex: All

Ages: 18 to 45 years old
