Detailed description: This study is a Phase 2a, parallel group, double blind, vehicle-controlled study of the safety and efficacy of ARQ-252 0.3% cream in combination with NB-UVB phototherapy treatment in subjects with non-segmental facial vitiligo.

This study was prematurely terminated by the sponsor on 30-Jun-2021.

Eligibility criteria: Inclusion Criteria:

* Subject is legally competent to sign and give informed consent.
* Males and females ages 18 years and older (inclusive)
* Clinical diagnosis of non-segmental vitiligo involving face.
* A Facial Vitiligo Area Severity Index \[F-VASI\] score of ≥ 0.25 at baseline.
* Vitiligo of the face involving at least ≥ 0.25% body surface area (BSA) involvement (ie, one quarter of one handprint). Subjects may have non-facial vitiligo elsewhere which will not be included in the minimum BSA. The maximum BSA (total body inclusive of the face, whether or not in areas to be treated in this study) permitted is 15%.
* Subjects with vitiligo on the hands, forearms, or elbows agree to treat these areas in addition to the face, with investigational product and phototherapy.
* Subject agrees to discontinue all agents used to treat vitiligo from screening through the final safety follow-up visit. Over-the-counter preparations deemed acceptable by the Investigator and camouflage makeups are permitted.
* Female subject of childbearing potential (FOCBP) must have a negative serum pregnancy test at Screening and negative urine pregnancy test at Baseline (Visit 2). For FOCBP involved in any sexual intercourse that could lead to pregnancy: the subject must agree to use a highly effective contraceptive method for at least 4 weeks prior to Day 1. Additionally, from Day 1 until at least 4 weeks after the last investigational product administration, these subjects must agree to use at least 1 highly effective contraceptive method in addition to 1 barrier method.
* Female subject of non-childbearing potential must either be post-menopausal with spontaneous amenorrhea for at least 12 months prior to baseline (post-menopausal status will be confirmed with FSH testing) or have undergone surgical sterilization.
* Males, if engaging in sexual intercourse with a female who is pregnant or a female of child-bearing potential, must agree to use a condom every time during the study and every time subsequently until 4 weeks beyond the last dose of investigational product.
* Males must agree not to donate sperm from the first dose of investigational product until 4 weeks after the last dose of investigational product.
* Subject is in good health as judged by the Investigator, based on medical history, physical examination, 12-lead electrocardiogram (ECG), serum chemistry labs, hematology values, and urinalysis.

Exclusion Criteria:

* Subjects who have ever used skin bleaching treatments for treatment of vitiligo or other pigmented areas, eg, depigmenting agents such as monobenzyl ether of hydroquinone, including Benoquin® (Monobenzone)
* Use of any other prior and concomitant therapy that is a contraindication to phototherapy or may otherwise interfere with the objective of the study as per discretion of the Investigator, such as drugs that cause photosensitivity or skin pigmentation (eg, antibiotics such as tetracyclines, antifungals) within 8 weeks of Baseline (Visit 2).
* More than 33% leukotrichia in facial lesions (assessed via dermatoscope).
* Other forms of vitiligo (eg, segmental vitiligo); or other skin depigmentation disorder that would confound study assessments.
* Use of oral or systemic immunomodulating medications (eg, corticosteroids, azathioprine, methotrexate, cyclosporine) within 8 weeks of Baseline (Visit 2).
* Use of prescription or over-the-counter topical treatments that may affect vitiligo (eg, corticosteroids, tacrolimus/pimecrolimus, retinoids, vitamin D derivates, psoralens) within 4 weeks prior to Baseline (Visit 2).
* Use of any biological or experimental therapy for vitiligo within 24 weeks of Baseline (Visit 2) (or 5 half-lives, whichever is longer).
* Use of phototherapy (including laser and tanning beds) within 8 weeks prior to Baseline (Visit 2).
* Previous oral or topical JAK inhibitor therapy within 24 weeks prior to Baseline (Visit 2), and/or prior non-response to oral or topical JAK inhibitor therapy for vitiligo
* History of melanocyte-keratinocyte transplantation procedure (MKTP) or other surgical treatment for vitiligo.
* Contraindication to phototherapy, such as photosensitivity disorder (eg, lupus, polymorphic light eruption, solar urticaria, dermatomyositis) or use of photosensitizing or phototoxic medications.
* Subjects with clinically significant abnormal thyroid-stimulating hormone or free T4 at screening, or otherwise uncontrolled thyroid function at screening as determined by the investigator (Note: If the subject has a history of thyroid disease and is on treatment, the participant must be on a stable thyroid regimen for at least 3 months prior to baseline)
* History of chronic alcohol or drug abuse within 6 months prior to baseline.
