ListOutcomeTime frameDescription
PrimaryNumber of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)From start of study drug administration until week 182
An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received investigational product. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between administration of investigational product and 30 days after the last dose of study drug that were absent before treatment or that worsened relative to pre-treatment state.
SecondaryMaximum Observed Serum Concentration (Cmax) for SifalimumabPre-infusion and End of Infusion on Day 1The Cmax is the maximum observed plasma concentration of sifalimumab.
SecondaryTime to Reach Maximum Observed Plasma Concentration (Tmax) of SifalimumabPre-infusion and End of Infusion on Day 1The Tmax is the time to reach maximum observed plasma concentration of sifalimumab.
SecondaryTime to Last Quantifiable Plasma Concentration (Tlast) of SifalimumabPre-infusion and End of Infusion on Day 1The Tlast is the time to last quantifiable plasma concentration (Tlast) of sifalimumab.
SecondaryMinimum Observed Serum Concentration (Ctrough) of SifalimumabPre-infusion and End of Infusion on Day 1The Ctrough is the minimum observed serum concentration of sifalimumab.
SecondaryArea Under the Serum Concentration-time Curve Over the Dosing Interval (AUCtau) of SifalimumabPre-infusion and End of Infusion on Day 1The AUCtau is the area under the serum concentration-time curve over the dosing interval of sifalimumab.
SecondaryMinimum Observed Serum Concentration at Steady State (Ctrough,ss) of SifalimumabPre-infusion and End of Infusion on Day 1 and Week 2, 4, 8, 12, 24, 52, 104, 156 and 168The Ctrough is the minimum observed serum concentration at steady state of sifalimumab.
SecondaryAccumulation Index for Minimum Observed Serum Concentration (Ctrough) of SifalimumabPre-infusion and End of Infusion on Day 1 and Week 2, 4, 8, 12, 24, 52, 104, 156 and 168The Ctrough is the minimum observed serum concentration of sifalimumab. Accumulation Index is calculated as Ctrough value at steady state divided by Ctrough value after first dose.
SecondaryNumber of Participants With Positive Anti-Drug AntibodyDay 1 and Week 12, 24, 52, 104, 156 and 168Participants tested for immunogenicity to Sifalimumab (MEDI-545) from Day 1 to the end of study.
