简要总结
The purpose of this pharmacokinetic (PK) study is to describe the PK profile of ianalumab following s.c. administration in Chinese participants with systemic lupus erythematosus (SLE) and/or Sjögren's disease (SjD). Collection of intensive PK data from Chinese population had been designed in the ianalumab Phase 3 studies of SjD CVAY736A2302 (NCT05349214) and lupus nephritis (LN) CVAY736K12301 (NCT05126277) on an optional basis. This study is conducted to provide supplementary Chinese PK data in addition to the intensive PK data from the two Phase 3 studies .
详细描述
The study consists of the following periods:
- Screening Period: up to 4 weeks
- Treatment Period (Week 0 - Week 12) : 12 weeks
- Extended Treatment Period (after the completion of Week 12 - Week 52 (End of Treatment (EoT)) : 40 weeks
~ After completion of the 12-week treatment, participants will have the option to enter the Extended Treatment Period. If a participant does not enter the Extended Treatment Period, the EoT visit will be performed at the next planned visit following the completion of Week 12, followed by the Post-treatment Follow-up Period.
- Post-treatment Follow-up Period: at least 20 weeks and up to 2 years from the last dose of study treatment.

结局指标
主要结局
Area Under the Curve (AUC) calculated to the end of a dosing interval (tau) at steady-state (AUCtau) of ianalumab after the 3rd dose
时间窗: Week 8 to 12 (Day 57): Pre-dose, Post-dose (24 hours (hr) +/- 12hr, 72 hr +/- 24 hr, 168 hr +/- 72 hr, 336 hr +/- 72hr, 504 hr +/- 72hr)
Venous whole blood samples will be collected for activity-based pharmacokinetics characterization of ianalumab. AUCtau of ianalumab will be summarized with descriptive statistics.
