Criteria
Inclusion Criteria:

1. Subject has a clinical diagnosis of new onset or actively progressing non-segmental
facial vitiligo or worsening of existing facial lesions within the past 6 months.

2. Subject has non-segmental facial vitiligo effecting at least 0.25% total body surface
area (TBSA) (excluding the upper and lower eyelids, mucosal lip areas and forehead and
chin areas covered by the stereotactic positioning device for photography) with at
least one area of the face with normal pigmentation.

3. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test at
the screening visit and a negative urine pregnancy test at the baseline visit and must
agree to use an approved method of highly effective birth control for the duration of
the study and for 30 days after last study medication application.

4. Subject is in good general health and free of any known disease state or physical
condition which, in the opinion of the investigator, would interfere with the study
assessments or put the subject at undue risk by study participation.

5. Subject agrees to refrain from any other treatments for vitiligo from the screening
visit through the final follow-up visit. Over the counter (OTC) preparations deemed
acceptable by the investigator and camouflage makeups are permitted.

Exclusion Criteria:

1. Subject with evidence of poliosis (white hairs) in > 50% of their facial vitiligo
lesions.

2. Subject with total facial depigmentation.

3. Subject with spontaneous ongoing repigmentation (documented based on the subject's
reporting in the last 3 months).

4. Subject who has segmental vitiligo.

5. Subject who has failed phototherapy. Failed phototherapy is defined as failure to
achieve satisfactory repigmentation following adequately delivered phototherapy as
determined by the investigator.

6. Subject currently has, or has a history of, skin disease (e.g., psoriasis, seborrheic
dermatitis, etc.) that, in the opinion of the investigator, would interfere with the
study medication application or study assessments.

7. Subject has, or has a history of, severe, progressive or uncontrolled autoimmune,
metabolic, renal, hepatic, gastrointestinal, pulmonary, cardiovascular, genitourinary
(i.e.,renal disease), hematological disease, neurologic or cerebral disorders,
infectious disease or coagulation disorders that, in the opinion of the investigator,
would interfere with the study assessments or put the subject at undue risk by study
participation.

8. Subject currently has a history of, current, or suspected systemic or cutaneous
malignancy and/or lymphoproliferative disease, other than a history of adequately
treated, well healed and completely cleared non-melanoma skin cancers (e.g., basal or
squamous cell carcinoma) treated successfully at least 1 year prior to study entry
with no evidence of disease.

9. Subject currently has evidence of active or latent bacterial (including tuberculosis)
or viral infections at the time of enrollment, or a history of incompletely treated or
untreated tuberculosis. Subjects who have initiated therapy for latent tuberculosis
for at least 2 weeks and agree to continue their therapy through completion may
participate.

10. Subject has a history of serious local infection (e.g., cellulitis, abscess) or
systemic infection, or history of treated infection (e.g., pneumonia, septicemia)
within 3 months prior to the baseline visit. Subjects on an antibiotic for a
nonserious, acute local infection must complete the course prior to enrollment into
the study.

11. Subject has herpes zoster or cytomegalovirus (CMV) that resolved within 8 weeks prior
to Visit 1.

12. Subject has a history of frequent outbreaks of oral Herpes Simplex Virus defined as
more than 4 episodes per year.

13. Subjects previously treated with depigmenting agents.

14. Clinically significant laboratory abnormalities at screening that in the opinion of
the investigator, would make the subject a poor candidate for the study.

15. Subject who has an absolute neutrophil count <1,000/mm3, or platelet count <
50,000/mL.

16. Subject unable to comply with the required washout periods

17. Subject who has participated in any investigational drug or device trial, regardless
of indication in which administration of an investigational drug or device occurred
within 30 days or 5 half-lives (whichever is longer) of screening (Visit 1). Note that
investigational treatment for vitiligo (in any body area) requires a longer washout

18. Subjects with a clinically significant abnormal thyroid-stimulating hormone or free T4
at screening. Subjects under treatment with stable thyroid replacement who have a free
T4 and TSH within the normal range may participate.

19. Subject has history of sensitivity to any of the ingredients in the study medication.

20. Subject has a history of, or current alcohol or drug abuse within 2 years of study
enrollment.

21. Screening ECG findings of:

1. QTcF >450msec for males or >470msec for females (use of the ECG algorithm is
acceptable for this purpose)

2. Heart rate ≤ 45 or ≥ 100 beats/minutes

3. Rhythm disturbance other than sinus arrhythmia or ectopic supraventricular rhythm
(ectopic atrial rhythm)

4. Conduction disturbance including PR >240msec, pre-excitation (delta wave and PR
<120msec), second degree or higher AV block

5. Acute or chronic signs of ischemia.

6. Left Bundle Branch Block

7. Prior myocardial infarction
