Intervention Type: Other, Drug
Study Type: Interventional
Study Phase: Phase 1
SUMMARY

The goal of this clinical trial is to learn if drug CGB-600 works to treat vitiligo on the face and neck in participants between 18-60 years of age. It will also learn about the safety of CGB-600. The main questions it aims to answer are: Does CGB-600 decrease the severity of vitiligo on the face and neck? What medical problems do participants have when taking drug CGB-600? Researchers will compare CGB-600 to a non-active drug (vehicle) to see if CGB-600 works to treat vitiligo. Participants will: Apply face twice daily for a period of 24 weeks. Visit the clinic 8 times for checkups and tests.
