Primary Outcome Measures
NameTimeMethod
Proportion of Patients With Complete TMA ResponseThrough 26 weeks

Proportion of Patients with Complete TMA response was determined and defined by normalization of hematological parameters (platelet count and LDH) and ≥ 25% improvement in serum creatinine from baseline which was sustained for at least two consecutive measurements obtained at least four weeks apart).

Secondary Outcome Measures
NameTimeMethod
Proportion of Patients With Complete Hematologic ResponseThrough End of Study, Median Exposure 55 Weeks

Proportion of Patients with Complete Hematologic response through end of study was determined and defined by normalization of platelet count and LDH sustained for at least two consecutive measurements obtained at least four weeks apart.

Proportion of Patients With Platelet Count NormalizationThrough End of Study, Median Exposure 55 Weeks

Proportion of Patients with Platelet Count Normalization through end of study was determined and defined as the platelet count observed to be ≥ 150 x 109/L on at least two consecutive measurements which span a period of at least four weeks

Proportion of Patients With Estimated Glomerular Filtration Rate (eGFR) ImprovementThrough End of Study, Median Exposure 55 Weeks

Proportion of Patients with Estimated Glomerular Filtration Rate (eGFR) Improvement was determined and defined as an increase in eGFR by ≥ 15 mL/min/1.73m2 from baseline, sustained for at least two consecutive measurements obtained at least four weeks apart.

Platelet Count Change From Baseline to 26 WeeksThrough 26 weeks
Proportion of Patients With Complete TMA ResponseThrough End of Study, Median Exposure 55 Weeks

Proportion of Patients with Complete TMA response was determined and defined by normalization of hematological parameters (platelet count and LDH) and ≥ 25% improvement in serum creatinine from baseline which was sustained for at least two consecutive measurements obtained at least four weeks apart).
