Arm && Interventions

Group	Intervention	Description
Phototherapy associated with placebo	Placebo	Placebo once a day orally for 36 weeks + UVB TL01: 2 times a week during 24 weeks. (Phototherapy will be started 12 weeks after the beginning of placebo of baricitinib).
Phototherapy associated with active treatment	Baricitinib Oral Product	Baricitinib 4 mg/day orally for 36 weeks + UVB TL01: 2 times a week during 24 weeks. (Phototherapy will be started 12 weeks after the beginning of baricitinib)

Primary Outcome Measures

Name	Time	Method
Score with Vitiligo Area Scoring Index (VASI)	week 36	The VASI Score is used to assess the severity and extent of Vitilgo. VASI is calculated using a formula that includes contributions from all body regions (possible range, 0-100). The body is divided into 6 separate and mutually exclusive sites (head/neck, hands, upper extremities \[excluding hands\], trunk, lower extremities \[excluding feet\], and feet), with percentage of vitiligo involvement estimated in hand units by the same investigator throughout the study.

Secondary Outcome Measures

Name	Time	Method
Score with VASI score	week 48	Change in percentage of repigmented Surface area 48 weeks after-inclusion, by using the VASI score at week 48.; The VASI Score is used to assess the severity and extent of Vitilgo. VASI is calculated using a formula that includes contributions from all body regions (possible range, 0-100). The body is divided into 6 separate and mutually exclusive sites (head/neck, hands, upper extremities \[excluding hands\], trunk, lower extremities \[excluding feet\], and feet), with percentage of vitiligo involvement estimated in hand units by the same investigator throughout the study.
Number of Adverse Events (AE) and serious adverse events (SAE), as well as the proportion of discontinuation due to AEs and/or SAEs	week 36	AE is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related, that occurs after a subject provides informed consent. Abnormal laboratory values or test results occurring after informed consent constitute AEs only if they induce clinical signs or symptoms, are considered clinically meaningful, require therapy, or require changes in the study drug.
Evaluation of score Vitiligo European Task Force (VETF)	Week 24	Variation of the score Vitiligo European Task Force (VETF) The VETF score is used to assess the severity and extent of vitiligo. The VETF assesses 3 dimensions of the disease in 5 areas (Head/neck, hands and feet, trunk, arms, legs) namely 1/ extent: percentage of vitiligo involvement estimated using the rule of nines, 2/ depigmentation severity grading (stage 0: normal pigmentation Stage 1: incomplete pigmentation , stage 2 complete depigmentation, stage 3: partial hair whitening \<30% stage 4: complete hair whitening) and 3/ spreading (score O: similar limits, Score 1: progressive vitiligo; score -1: regressive vitiligo).
Evaluation of blood inflammatory markers using immunofluorescence on skin biopsies and ELISA multiplex.	week 36	Expression of IFN-α, TNF-α, IFN-γ, IL-4, IL-5, IL-12, IL-13, IL-15, IL-17, IL-22, IL-23, IL-33 CXCL4, CXCL9, CXCL10, CXCL11, CXCL12, CXCL16, CCL20, soluble HSP70.
Evaluation of Face Vitiligo Aera Scoring Index (F-VASI) score	week 48	Mean variation in percentage of Face Vitiligo Aera Scoring Index (F-VASI) score between baseline , week 48
Evaluation of score of the Vitiligo Extent Score (VES)	Week 48	Variation in percentage of the Vitiligo Extent Score (VES). The VES score is used to assess the severity and extent of vitiligo. Using the VES calculator www.vitiligo-calculator.com, investigator choose the pictures that best represent the patient's skin lesions and then the percentage of depigmented area is calculated.
Evaluation of score of the Vitiligo Signs of Activity Score (VSAS)	Week 48	Variation in percentage of the Vitiligo Signs of Activity Score (VSAS). The VSAS score is used to assess the activity of the disease. It is assessed by evaluating the number of location with at least one disease sign of activity.
Evaluation of the score of the Skindex 29	Week 48	Variation of the score of the Skindex 29. SkinDex29 is a 30-item instrument, each item scored from 1 to 5 where higher scores correspond to worse symptom impact, full range from 0 to 150.
Evaluation of score of the Dermatology Life Quality Index (DLQI)	week 48	Variation of the score of the Dermatology Life Quality Index (DLQI). DLQI is a 10-item instrument, each item scored from 0 to 3 where higher scores correspond to worse symptom impact, full range from 0 to 30.
