Phase 2
Recruiting
Conditions
Non-segmental Vitiligo
Interventions
Drug: placebo
Registration Number
NCT06511739
Lead Sponsor
CSPC Ouyi Pharmaceutical Co., Ltd.
Brief Summary

A 52-Week Study of SYHX1901 tablet in Adults with non-segmental vitiligo.

Detailed Description

SYHX1901 tablet is being evaluated for the treatment of non-segmental vitiligo. The study will enroll approximately 144 participants aged 18-65 with non-segmental vitiligo in 4 treatment arms. Participants will either receive study drug vs placebo oral tablets once daily (QD) for 24 weeks (Period A). In Period B (up to 52 weeks), participants who received placebo during the first 24 weeks will switch to study drug. Participants who received study drug during the first 24 weeks, will continue to receive study drug.

Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Facial-Vitiligo Area Scoring Index (F-VASI)At 24 weeks

The vitiligo area scoring index (VASI) is a validated scoring method used to assess the areas of depigmentation due to vitiligo. The F-VASI includes contributions from the face, with a possible range from 0 to 3.5.

Secondary Outcome Measures
NameTimeMethod
Percent Change From Baseline in F-VASIAt 4、8、12、16、20、24、28、32、36、40、44、48、52、56 weeks

The VASI is a validated scoring method used to assess the areas of depigmentation due to vitiligo. The T-VASI is calculated using a formula that includes contributions from all body regions, with a possible range from 0 to 100.

Percent Change From Baseline in BSAAt 4、8、12、16、20、24、28、32、36、40、44、48、52、56 weeks

The BSA is measured by the number of hand units (palm plus 5 digits = 1% body surface area).

Percentage of Participants Achieving Total Vitiligo Area Scoring Index (T-VASI) 50 (≥ 50% Improvement in T-VASI From Baseline)At 4、8、12、16、20、24、28、32、36、40、44、48、52、56 weeks

The VASI is a validated scoring method used to assess the areas of depigmentation due to vitiligo. It is based on a composite estimate of the overall area of vitiligo patches, measured by the number of hand units (palm plus 5 digits = 1% body surface area \[BSA\]) multiplied by the degree of depigmentation within each affected area (0%, 10%, 25%, 50%, 75%, 90%, or 100%). The T-VASI is calculated using a formula that includes contributions from all body regions, with a possible range from 0 to 100.

Change from baseline in Overall Dermatology Life Quality Index (DLQI) scoreAt 8、16、24、32、40、48、52、56 weeks

The DLQI is a validated questionnaire used in dermatology clinical trials as patient reported outcome measure. The DLQI consists of 10 questions concerning patients' perception of the impact of skin diseases on different aspects of their health-related quality of life over the last week.

Change from baseline in Hospital Anxiety and Depression Scale (HADS) scoreAt 8、16、24、32、40、48、52、56 weeks

The HADS is a self-rating patient reported outcome measure (PROM) to assess depression and anxiety in patients. Fourteen items are equally divided in two subscales: anxiety (HADS-A) and depression (HADS-D).

Percentage of Participants Achieving F-VASI 50 (≥ 50% Improvement in F-VASI From Baseline)At 4、8、12、16、20、24、28、32、36、40、44、48、52、56 weeks

The VASI is a validated scoring method used to assess the areas of depigmentation due to vitiligo. The F-VASI includes contributions from the face, with a possible range from 0 to 3.5.

Percentage of Participants Achieving F-VASI 75 (≥ 75% Improvement in F-VASI From Baseline)At 4、8、12、16、20、24、28、32、36、40、44、48、52、56 weeks

The VASI is a validated scoring method used to assess the areas of depigmentation due to vitiligo. The F-VASI includes contributions from the face, with a possible range from 0 to 3.5.
