简要总结
This extension study (CZPL389A2203E1) was designed as a 2-year (100 weeks) extension to the core study (CZPL389A2203/ NCT03517566) which is disclosed separately. It aimed to assess the short-term and long-term safety of (blinded) 30 mg o.d and 50 mg o.d ZPL389 with concomitant or intermittent use of topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI).
详细描述
Subjects who had received ZPL389 30 mg or 50 mg doses in the core study (CZPL389A2203), continued to receive the same doses in double-blinded fashion. Subjects who had received ZPL389 3 mg, 10 mg or placebo in the core study were randomized to 30 mg or 50 mg ZPL389 in a 1:1 ratio. All subjects received concomitant or intermittent TCS and/or TCI along with ZPL389. Short-term safety was assessed up to week 16 of this extension study (week 16 to week 32 referring to the start of core study treatment) and long-term safety was assessed after week 16 of this extension study (after week 32 referring to the start of core study treatment). The entire planned time frame (100 weeks) was not assessed as originally planned due to early termination of the core and extension studies.

结局指标
主要结局
Number of Patients With Adverse Events in the First 16 Weeks of This Extension Study
时间窗: 16 weeks (week 16 to week 32 referring to core study)
An adverse event (AE) is any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a subject or clinical investigation subject after providing written informed consent for participation in the study until the end of study visit. Therefore, an AE may or may not be temporally or causally associated with the use of a medicinal (investigational) product. As all patients were rolling over from the core study CZPL389A2203, in addition to the time frame referring to the start in this extension study, the time frame corresponding to the start in the core study (+16 weeks) are provided in parenthesis.
Number of Patients With Adverse Events After 16 Weeks of Treatment in This Extension Study
时间窗: From week 16 to week 67 of this extension study (week 32 to week 83 referring to core study)
An adverse event (AE) is any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a subject or clinical investigation subject after providing written informed consent for participation in the study until the end of study visit.
