简要总结
This study investigated the safety and tolerability of VAY736 administered as single ascending doses of intravenous infusion, subcutaneous injection and repeated subcutaneous injections in rheumatoid arthritis patients.
详细描述
This study had three sequential parts which investigated the safety and tolerability of VAY736 administered as single ascending doses of intravenous infusion (Part 1), single ascending doses of subcutaneous injection (Part 2), and repeated subcutaneous injections of fixed doses (Part 3), respectively, in rheumatoid arthritis patients. Part 1 was double blind, placebo controlled, with 11 cohorts. Part 2 was open-label study with 2 dosing cohorts. Part 3 was open-label study with 1 fixed-dose cohort.

结局指标
主要结局
Safety and tolerability as measured by the number of patients wth adverse events
时间窗: 27-188 weeks
Part 1 The number of patients with adverse events after single intravenous (i.v.) dose of VAY736. Patients are assessed weekly up to 34 weeks post dose or until B cells reach the recovery criteria Part 2 The number of patients with adverse events after single subcutaneous (s.c.) dose of VAY736. Patients are assessed weekly, bi-weekly, then every 4, 8 and 12 weeks up to 188 weeks post dose or until B cells reach the recovery criteria. Part 3 The number of patients with adverse events after repeated subcutaneous (s.c) injections of a fixed dose of VAY736. Patients are assessed bi-weekly, then every 4 weeks and 8 weeks up to 27 weeks from the first dose.
Absolute bioavailability of VAY736: The ratio of area under curve (AUC) for s.c dose and for intravenous dose
时间窗: 188 weeks
Part 2 The ratio of area under curve (AUC) for single s.c dose and intravenous dose is determined
Plasma pharmacokinetics of VAY736: The area under the plasma concentration-time curve from time zero to the end of the dosing interval (AUCtau)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, the area under the plasma concentration-time curve from time zero to the end of the dosing interval (AUCtau) will be determined
Plasma pharmacokinetics of VAY736: Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration (AUClast)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, the Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration (AUClast) will be determined.
Plasma pharmacokinetics of VAY736: Observed maximum plasma concentration following drug administration (Cmax)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, the Observed maximum plasma concentration following drug administration (Cmax) will be determined
Plasma pharmacokinetics of VAY736: Time to reach the maximum concentration after drug administration (Tmax)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, the time to reach the maximum concentration after drug administration (Tmax) will be determined
Plasma pharmacokinetics of VAY736: The terminal elimination half-life (T1/2)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, the terminal elimination half-life (T1/2) will be determined
Plasma pharmacokinetics of VAY736: Area under the plasma concentration-time curve from time zero to infinity (AUCinf)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, Area under the plasma concentration-time curve from time zero to infinity (AUCinf) will be determined.
Plasma pharmacokinetics of VAY736: concentration of VAY736 during the treatment period, before each dose (Ctrough)
时间窗: 27 weeks
In Part 3: After the first and last s.c. doses, the concentration of VAY736 during the treatment period, before each dose (Ctrough) will be determined
Safety and tolerability as measured by the percentage of patients wth adverse events
时间窗: 27-188 weeks
Part 1 The percentage of patients with adverse events after single intravenous (i.v.) dose of VAY736. Patients are assessed weekly up to 34 weeks post dose or until B cells reach recovery criteria. Part 2 The percentage of patients with adverse events after single subcutaneous (s.c.) dose of VAY736. Patients are assessed weekly, bi-weekly, then every 4, 8 and 12 weeks up to 68 weeks post dose or until B cells reach recovery criteria.. Part 3 The percentage of patients with adverse events after repeated subcutaneous (s.c) injections of a fixed dose of VAY736. Patients are assessed bi-weekly, then every 4 weeks and 8 weeks up to 27 weeks from the first dose.
