ListOutcomeTime frameDescription
PrimaryPercentage of Patients With TMA Event-free StatusThrough 26 weeks
TMA Event-free status is defined as the absence for at least 12 weeks of \[1\] decrease in platelet count of \> 25% from the Platelet Count Pre-PT Baseline Set Point; \[2\] PT while the patient is receiving eculizumab, and \[3\] new dialysis.
PrimaryPercentage of Patients With Hematologic NormalizationThrough 26 weeks
Hematologic Normalization was defined as normalization of both platelet count and lactic dehydrogenase (LDH) sustained for at least two consecutive measurements which spanned a period of at least four weeks.
PrimaryPercentage of Patients With Complete TMA ResponseThrough 26 weeks
The proportion of patients who achieved a Complete TMA Response from baseline through 26 weeks of treatment with eculizumab was determined. Complete TMA Response was defined as Hematologic Normalization plus improvement in renal function (defined as (≥25% reduction from baseline in serum creatinine), which was sustained for two consecutive measurements over a period of at least four weeks.
SecondaryTMA Intervention RateThrough 26 weeks
TMA Intervention Rate (# PE/PI and # Dialysis Events/Patient/Day) in the eculizumab treatment period (from baseline through 26 weeks) for PE/PI and (from the fifteenth day following the first eculizumab dose through 26 weeks) for new dialysis events was compared with the TMA Intervention Rate during the pre-eculizumab treatment period.
SecondaryPlatelet Count Change From Baseline to 26 WeeksFrom Baseline to 26 Weeks
SecondaryPercentage of Patients With Platelet Count NormalizationThrough 26 WeeksPlatelet count normalization was defined as the platelet count observed to be ≥150 x 10\^9/L on at least two consecutive measurements which span a period of at least four weeks
SecondaryPercentage of Patients With TMA Event-free StatusThrough End of Study, Median Exposure 156 Weeks
TMA Event-free status is defined as the absence for at least 12 weeks of \[1\] decrease in platelet count of \> 25% from the Platelet Count Pre-PT Baseline Set Point; \[2\] PT while the patient is receiving eculizumab, and \[3\] new dialysis.
SecondaryPercentage of Patients With Hematologic NormalizationThrough End of Study, Median Exposure 156 Weeks
Hematologic Normalization was defined as normalization of both platelet count and lactic dehydrogenase (LDH) sustained for at least two consecutive measurements which spanned a period of at least four weeks.
SecondaryPercentage of Patients With Complete TMA ResponseThrough End of Study, Median Exposure 156 Weeks
The proportion of patients who achieved a Complete TMA Response from baseline through end of study with eculizumab was determined. Complete TMA Response was defined as Hematologic Normalization plus improvement in renal function (defined as (≥25% reduction from baseline in serum creatinine), which was sustained for two consecutive measurements over a period of at least four weeks.
SecondaryTMA Intervention RateThrough End of Study, Median Exposure 156 Weeks
TMA Intervention Rate (# PE/PI and # Dialysis Events/Patient/Day) in the eculizumab treatment period (from baseline through end of study) for PE/PI and (from the fifteenth day following the first eculizumab dose through end of study) for new dialysis events was compared with the TMA Intervention Rate during the pre-eculizumab treatment period.
SecondaryPlatelet Count Change From Baseline to 156 WeeksFrom Baseline to 156 Weeks
SecondaryPercentage of Patients With Platelet Count NormalizationThrough End of Study, Median Exposure 156 WeeksPlatelet count normalization was defined as the platelet count observed to be ≥150 x 10\^9/L on at least two consecutive measurements which span a period of at least four weeks Not specified.
SecondaryPharmacokinetics (PK) and Pharmacodynamics (PD); Minimum and Maximum Blood ConcentrationInduction Phase for 4 weeks followed by Maintenance Phase starting on Week 5 through 26 weeks or longer.
