Primary Outcome Measures
NameTimeMethod
Total Kidney VolumeBaseline, Week 48, 96, 144, and 192

Individual subject data on the volumes of the total kidney volume (sum of the volumes of the left and right kidneys) measured by magnetic resonance imaging or computed tomography during trial period.

Repeated oral administration at doses of 15 mg twice daily (morning and evening) until approval of the revised protocol (Edition 4.0) by the IRB of each trial site.

Number of participants analyzed at each time point represents number of participants with data at the specified time point. Patients who were withdrawn from trial or have no appropriate data (e.g., interruption of medication, protocol deviation, etc.) are excluded.

Renal Function Test (eGFR)Baseline, Week 48, 96, 144, and 192

Individual subject data on eGFR (estimated glomerular filtration rate calculated by Japanese eGFR equation) during trial period.

Number of participants analyzed at each time point represents number of participants with data at the specified time point. Patients who were withdrawn from trial or have no appropriate data (e.g., interruption of medication, protocol deviation, etc.) are excluded.
