简要总结
This is an open-label, multi-center, Phase 3 study to evaluate tapinarof cream, 1% in pediatric subjects with plaque psoriasis.
详细描述
This study is an open-label study, consisting of a 12-week primary treatment phase and an optional 40-week long-term extension phase in which all eligible subjects will receive tapinarof cream, 1% once daily. At the end of the 12-week primary treatment phase subjects will have the option to continue for 40 additional weeks of treatment. Subjects who choose not to participate in the optional 40-week long-term extension phase will complete a follow-up visit approximately one week after the end of the primary treatment phase.

研究组 & 干预措施
Open Label
干预措施: tapinarof cream, 1% (Drug)
结局指标
主要结局
Adverse Events (AEs) and Serious Adverse Events (SAEs)
时间窗: Screening up to Week 53
Incidence, frequency, and duration of treatment emergent AEs and SAEs
Investigator-Assessed Local Tolerability Scale (LTS) Scores
时间窗: Baseline up to Week 52
Local Tolerability Scale (LTS) is a clinical tool for assessing the presence and overall degree of irritation at the application sites, according to a 5-point scale (0-4). Higher LTS scores represent more severe irritation.
Number of subjects with clinically significant laboratory test abnormalities
