cTMAr was defined by meeting all of the following criteria at two separate assessments, obtained at least 4 weeks (a minimum of 26 days) apart, and any measurement in between: Platelet count ≥ lower limit of normal (LLN); Lactate dehydrogenase (LDH) ≤ upper limit of normal (ULN); and ≥ 25% decrease in serum creatinine from baseline.
Participants with normalized creatinine (i.e., LLN ≤ creatinine ≤ ULN) at baseline were excluded from analysis.
95% confidence interval (CI) was calculated using Wilson's score method.

Naïve and Switch Cohorts: Observed Value of Estimated Glomerular Filtration Rate (eGFR), as Calculated From Central Serum Creatinine
時間枠:Baseline, Weeks 2, 3, 4, 5, 7, 9, 11, 13, 17, 21, and 25
|
GFR is an index of kidney function that describes the flow rate of filtered fluid through the kidneys.
It was categorized according to chronic kidney disease (CKD) staging criteria.
eGFR was calculated using the creatinine-based bedside Schwartz equation.
eGFR (milliliters per minute per 1.73 square meter [mL/min/1.73
m^2])=0.413*(height
[ht]/serum creatinine [sCr]), if height is expressed in centimeters, or 41.3*(ht/sCr), if height is expressed in meters.

Naïve and Switch Cohorts: Percentage of Participants With Change From Baseline to Week 25 (After 24 Weeks on Treatment) in CKD Stage, as Assessed Based on eGFR Calculated From Central Serum Creatinine
時間枠:From baseline up to Week 25
|
CKD stage was assessed using eGFR, calculated from central serum creatinine using Creatinine-based bedside Schwartz equation & classified according to National Kidney Foundation CKD staging criteria as follows: G1 (≥90 mL/min/1.73
m²; normal or high kidney function), G2 (60-89 mL/min/1.73
m²; mildly decreased kidney function), G3a (45-59 mL/min/1.73
m²; mildly to moderately decreased kidney function), G3b (30-44 mL/min/1.73
m²; moderately to severely decreased kidney function), G4 (15-29 mL/min/1.73
m²; severely decreased kidney function), & G5 (<15 mL/min/1.73
m²; kidney failure).
Change in CKD stage from baseline to Week 25 was categorized as improved (participants who improved in CKD stage from Baseline to Week 25 were based on the number of participants who completed 24 weeks and were not Stage 1 at baseline), stable (no change), or worsened (participants with CKD Stage 1 to 4 at baseline) among participants who completed 24 weeks of treatment.
Percentages have been rounded off.
