Clinical Study to Investigate the Safety and Effectiveness of RECELL for Repigmentation of Stable Vitiligo Lesions
Study Details
Study Description
Brief Summary
This is a prospective blinded within-subject randomized study to evaluate the application of Spray-On Skin™ Cells, prepared using the RECELL® Device for safe and effective repigmentation of ablated stable vitiligo lesions.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: All Participants (within patient control) All subjects will receive both RECELL and NV-UVB. Each subject will serve as their own Control, with a depigmented area receiving no RECELL treatment but receiving the same targeted NB-UVB as the investigational treatment area. Study treatment areas will be randomily assigned as Area A and Area B. Investigational treatment (RECELL) will be randomly allocated to either Area A or Area B. |
Device: Spray-On Skin™ Cells 1:20 followed by NB-UVB
Skin cell suspension at expansion ratio 1:20 (donor area : recipient area), prepared using the RECELL System, will be applied to an ablated (de-epithelialized) area of depigmentation, followed by targeted phototherapy using NB-UVB.
Device: NB-UVB only
Each subject will serve as their own control, with a portion (or similar) depigmented lesion receiving the same targeted NB-UVB without application of skin cell suspension.

Outcome Measures
Primary Outcome Measures
- Proportion of Responders for RECELL-treated areas versus Control at Week 24 [Week 24]
Responders are defined as study areas achieving ≥ 80% repigmentation as determined by the the Central Review Committee.
Secondary Outcome Measures
- Central Review Committee categorization of repigmentation [Week 24]
Central Review Committee categorization of repigmentation (0-25%, 26-50%, 51-79% and 80-100%) at Week 24
- Central review committee assessment of color matching at Week 24 [Week 24]
Color matching will be rated excellent, good, moderate, or poor
- Subject and Investigator global treatment success and donor site satisfaction [Week 24]
Subjects and Investigators to respond to satisfaction questions for their treatment areas and donor sites
- Subject-reported Vitiligo Noticeability Score for Week 24 vs baseline [Week 24]
Based upon photographs subject will report their vitiligo noticeability
- Investigator assessment of pigmentation responder for the study areas [Week 24]
Investigators to assess pigmentation response for study areas where response equals 80% or greater pigmentation
- Investigator assessment of repigmentation category [Week 24]
Investigator to look at subject photos and determine what percent the area has repigmented: 0-25, 26-50, 51-79 or 80-100
- Central Review Committee and Investigator assessment of pigmentation [Week 36 and 52]
Central Review Committee and Investigator assessment of pigmentation for the study areas at Week 36 and Week 52
- Investigator study area Vitiligo Area Scoring Index (VASI) scores, change from baseline [Week 24]
Evaluation of VASI score in study areas and change in score from pre-treatment
- Investigator assessment of color matching for the study areas [Week 24]
Color matching will be categorized as poor (0), moderate (1), good (2), or excellent (3). Hypopigmentation and hyperpigmentation, when present, will also be reported.
- Central Review Committee assessment of color matching [Week 36 and 52]
Central Review Committee assessment of color matching for the study areas at Week 36 and 52
- Patient Global Impression of Change - Vitiligo (PaGIC-V) [Week 24]
The subject's impression of their improvement is assessed using a 7-point scale
- Repigmentation durability [Week 52]
Repigmentation durability to be assessed by the Investigator and Central Review Committee (CRC). For RECELL responding study areas (i.e., study areas that achieved repigmentation at Week 24), the investigator and CRC will confirm by observation at the Week 52 visit, that at least 80% of the repigmentation remains relative to the subject's Week 24 photograph.
Eligibility Criteria
Criteria
Inclusion Criteria:
- Focal, segmental or generalized (i.e., nonsegmental) stable vitiligo, defined as no new depigmented areas nor any depigmented areas that have expanded in size within the preceding 12 months, regardless of whether the areas are intended to be used as study areas.
1a. Photo documentation (current and at least 12 months prior) of the patient's depigmented areas have been evaluated as stable by an independent Screening Committee.
-
The patient has not undergone topical treatment (e.g., steroids, tacrolimus) for the study areas within the past 90 days.
-
The patient has not undergone phototherapy (e.g., NB-UVB) for the study areas within the past 90 days.
-
The patient is a candidate for surgical intervention of a depigmented area, defined as a patient who has previously been compliant with but has not satisfactorily responded to both
- topical therapy and b. a minimum of 3 months of phototherapy.
-
The patient must have two study areas available for treatment that:
-
are of similar size (±50%),
-
are between 16cm2 and 456cm2 (contiguous),
-
are similarly sun exposed,
-
have the same extent of leukotrichia, and
-
are judged clinically as ≥90% depigmented (by area).
-
The patient is 18 years of age or older.
-
The patient is willing and able to comply with post-treatment at-home phototherapy and all follow-up evaluations required by the study protocol.
-
The patient agrees to abstain from any other treatment of the study areas for the duration of his/her participation in the study (52 weeks).
-
The patient agrees to abstain from enrollment in any other interventional clinical trial for the duration of his/her participation in the study (52 weeks).
-
In the opinion of the investigator, the patient must be able to:
- Understand the full nature and purpose of the study, including possible risks and adverse events, b. Understand instructions, and c. Provide voluntary written informed consent.
Exclusion Criteria:
-
The study areas selected have concomitant dermatologic conditions other than vitiligo.
-
The study area selected for treatment includes the lips, eyelids, plantar surface of feet, palmar surface of hands, fingertips, wrists, ankles, elbows, or knees.
