The safety emergent period was defined as the evaluation period from the analysis date of first drug intake up to 28 days after the end of treatment taking into account the different dosing frequencies of the study treatments. Data reported was analyzed by Kaplan-Meier estimate for cumulative proportion and the 95% confidence interval was calculated with Greenwood's formula. Percentage of participants were reported in this outcome measure. |

Number of Participants With End Stage Renal Disease (ESRD) |
Occurrence of end stage renal disease during the study (i.e from day 1 up to the end of study) was defined as at least one of the following: underwent >30 days dialysis therapy, received kidney transplant, planned kidney transplant, physician recommended renal replacement therapy and participant refused therapy, began dialysis and died < 30 days later. |
Baseline up to EOS (up to week 108) |

Time to Chronic Kidney Disease Progression (Composite of Doubling Serum Creatinine, Chronic Dialysis or Renal Transplant, and Death) |
Chronic kidney disease progression was defined as date of occurrence of chronic dialysis or date of renal transplant or doubled serum creatinine or date of death, whichever came first. For participants who had chronic dialysis or renal transplant or died, only their first occurrence during the safety emergent period was used. The safety emergent period was defined as the evaluation period from the analysis date of first drug intake up to 28 days after the end of treatment taking into account the different dosing frequencies of the study treatments. Data reported was analyzed by Kaplan-Meier estimate for cumulative proportion and the 95% confidence interval was calculated with Greenwood's formula. Percentage of participants were reported in this outcome measure. |

For participants who had chronic dialysis or renal transplant or died, only their first occurrence during the safety emergent period was used. The safety emergent period was defined as the evaluation period from the analysis date of first drug intake up to 28 days after the end of treatment taking into account the different dosing frequencies of the study treatments.

Time to at Least 40% Decrease in eGFR From Baseline, Chronic Dialysis or Renal Transplant |
For participants who had at least 40% decrease in eGFR from baseline, chronic dialysis or renal transplant during the safety emergent period, only their first occurrence was used. The safety emergent period was defined as the evaluation period from the analysis date of first drug intake up to 28 days after the end of treatment taking into account the different dosing frequencies of the study treatments. Data reported was analyzed by kaplan-meier estimate for cumulative proportion and the 95% confidence interval was calculated with Greenwood's formula. |

Number of Participants With Treatment Emergent Adverse Events (TEAEs) |
An AE was defined as any untoward medical occurrence in a participant who was given the study drug or who had undergone study procedures and did not necessarily have a causal relationship with this treatment. All AEs collected during the safety emergent period were counted as TEAE. The safety emergent period was defined as the evaluation period from the analysis date of first drug intake up to 28 days after the end of treatment taking into account the different dosing frequencies of the study treatments. Based on national cancer institute common terminology criteria (NCI-CTCAE), AEs were graded as grade 1=mild, grade 2=moderate, grade 3 =severe or medically significant, grade 4 =life threatening, grade 5 =death related to AE. All reported deaths after the first study drug administration and up to 28 days after the analysis date of last dose were based on last dosing frequency. |
