About
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.

Inclusion criteria
Adult (18 to 60 years old) diagnosed with non-segmental vitiligo on the face or neck. Dermoscopy and a Wood's Lamp Examination should be performed to confirm the diagnosis.
Facial and/or neck involvement with 1-3 vitiligo lesions (total combined area of lesions ≥ 6 cm² and ≤ 40 cm² and ≥75% depigmentation) for at least 3 months (90 days) prior to Baseline.
Vitiligo involvement ≤ 20% total body surface area (BSA).
Is otherwise in good health and free from any disease, condition, or constraint that, in the Investigator's opinion, might interfere with the conduct of the study
Stable disease, as judged by the investigator and patient report. Facial lesions must have been present ≤ 5 years with no new lesions or progression within 90 days prior to Baseline
Is not currently taking any medication for vitiligo in oral, topical, or any other form, including over-the-counter (OTC) and/or cosmetic products
Agrees to refrain from any other treatment modalities, including lights, lasers, or other medical devices, prescription or otherwise, for vitiligo for 4 weeks (28 days) before and during the study treatment (see Table 5.1 for complete list)
Agrees to refrain from using any lotions, creams, liquids, or other topical products at the treatment site during the study treatment period unless directed to do so by the investigator
Agrees to review and sign a written informed consent form
Can understand and comply with the study requirements as judged by the investigator

4. History of skin cancer or pre-cancerous lesions in the treatment area
5. Past use of topical or systemic vitiligo treatments within 4 weeks (28 days) prior to Baseline 6. Current active use of topical corticosteroids on the face or immunomodulatory therapies within 4 weeks (28 days) prior to Baseline
7. Use of biological, investigational, or experimental therapy 3 months before Baseline that could potentially interfere with the study participation or assessment
8. Known hypersensitivity to any components of the intervention or vehicle
9. History of melanocyte-keratinocyte transplantation procedure (MKTP) or other surgical treatments for vitiligo
10. Uncontrolled thyroid function or other medical conditions that could interfere with study participation or assessment

12. Has demonstrated resistance to previous JAKi treatment, topical or systemic
13. Has clinically significant laboratory anomalies or vital signs, as judged by the investigator, that would interfere with the conduct or interpretation of study results
14. Has any inflammations or any active skin diseases on the face and/or neck including complete leukotrichia or facial lesions that would interfere with study participation or assessment
15. Is currently participating in another investigational medication or device study or has participated in a clinical trial within 30 days of the intended start of study treatment
16. Is unable or unwilling to comply with any of the study requirements
17.
