About this trial

A Randomized, Double-Blind, Placebo Controlled, Multi-center Study to Evaluate the Safety and Efficacy of FB102 in Patients with Non-Segmental Vitiligo.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Males and females aged ≥ 18 to 75 years at time of Screening.

Must have confirmed non-segmental vitiligo criteria at the Screening Visit and the Baseline Visit, as assessed by the study investigator.

If receiving concomitant medications for any reason other than vitiligo, must be on a stable regimen, which is defined as not starting a new drug or changing dosage within 7 days or 5 half-lives (whichever is longer) prior to Day 1. Participant must be willing to stay on a stable regimen during the duration of the study.

Disqualifiers

Currently have active forms of other hypopigmentation (including but not limited to Vogt-Koyanagi-Harada disease, malignancy-induced hypopigmentation [melanoma and mycosis fungoides], post-inflammatory hypopigmentation, pityriasis alba [minor manifestation of atopic dermatitis], senile leukoderma [age-related depigmentation], chemical/drug-induced leukoderma, ataxia telangiectasia, tuberous sclerosis, melasma, and congenital hypopigmentation disorders including piebaldism, Waardenburg syndrome, hypomelanosis of Ito, incontinentia pigmenti, dyschromatosis symmetrica hereditaria, xeroderma pigmentosum, and nevus depigmentosus).

Currently have active forms of inflammatory skin disease(s) or evidence of skin conditions (including but not limited to morphea, discoid lupus, leprosy, syphilis, psoriasis, seborrheic dermatitis) at the time of the Screening or Day 1 Visit that in the opinion of the investigator would interfere with evaluation of vitiligo or response to treatment.

Greater than approximately 33% leukotrichia (depigmentation of the hair) in areas of vitiligo on the face as assessed by a healthcare professional at the time of screening.

Trial outcomes

Primary outcomes

1

Number of participants with treatment-emergent adverse events (TEAEs) and Serious Adverse events (SAE) following treatment with FB102

Time frame
Upto 16 Weeks post first dose administration
2

Percent change from Baseline in central read facial-vitiligo area scoring index (F-VASI)

The VASI Score is used to assess the severity and extent of Vitilgo. F-VASI is calculated using a formula that includes involvement of the face (possible range, 0-4), with percentage of vitiligo involvement estimated in finger units by the same investigator throughout the study

Time frame
Upto 16 Weeks post first dose administration
3

Number of participants with percent change from Baseline in central read facial-vitiligo area scoring index (F-VASI)

The VASI Score is used to assess the severity and extent of Vitilgo. F-VASI is calculated using a formula that includes involvement of the face (possible range, 0-4), with percentage of vitiligo involvement estimated in finger units by the same investigator throughout the study

Time frame
Upto 16 Weeks post first dose administration

Secondary outcomes

1

Proportion of participants achieving by percent change improvement in central read F-VASI from Baseline.

The VASI Score is used to assess the severity and extent of Vitilgo. F-VASI is calculated using a formula that includes involvement of the face (possible range, 0-4), with percentage of vitiligo involvement estimated in finger units by the same investigator throughout the study

Time frame
Upto 16 Weeks post first dose administration
2

To evaluate the efficacy of FB102 compared to placebo by percent change from Baseline in total-Vitiligo Area Scoring Index (T-VASI)

T-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

Time frame
Upto 16 Weeks post first dose administration
