Study Endpoints

Primary Endpoints

Mean Change From Baseline in Systolic Blood Pressure
Baseline and Day 21

Sitting blood pressure (\[BP\] or supine if child could not sit) was measured after the participant had been seated for 5 minutes with back supported, feet on the floor and right arm (or left arm if it was the customary side for BP measurement for the patient) supported at heart level. Systolic BP was determined by averaging 3 replicate measurements obtained at least 1 minute apart.

Number of Participants Who Reported 1 or More Clinical and/or Laboratory Adverse Event(s)
up to 12 weeks (Base Study); up to 24 months (Extension)
Number of Participants Who Were Discontinued From Study Due to a Clinical and/or Laboratory Adverse Event

Double-Blind Treatment Phase: Percent Change From Baseline in Urinary Protein/Creatinine (Pr/Cr) Ratio (gm/gm) at Week 12
Baseline and Week 12

Change in urinary protein excretion, determined as urinary Pr/Cr ratio compared to baseline\*, after approximately twelve weeks of treatment. Baseline is defined as values obtained at Visit 3, Week (-1) during the Single Blind Run-in period.

Open Label Extension: Percent Change From Baseline of Urinary Pr/Cr Ratio (gm/gm) at Month 36
Baseline and Month 36

Change in urinary protein excretion, determined as urinary Pr/Cr ratio compared to baseline\*, after approximately three years of treatment. \*The baseline for efficacy data in the extension was defined as the last value obtained in the double-blind treatment phase.

Open Label Extension: Change From Baseline in Glomerular Filtration Rate (GFR) at Month 36
Baseline and Month 36

The outcome measure of glomerular filtration rate was based on mL/min/1.73m\^2, as determined by the Schwartz formula: GFR = \_\_\_\_\_0.55 x height (cm)\_\_\_\_\_\_\_ divided by serum creatinine (mg/dL) GFR values were compared to the baseline GFR measure. \[Note: For male participants, ages 13 to 17 years, 0.70 was used as the multiplier in place of 0.55\] Baseline in regard to the extension is defined as the last value obtained in the double-blind treatment phase.

Mean Augmentation Index Percent Change From Baseline After Single Doses of Losartan 100 mg Plus ISMN 60 mg Versus Single Dose of Losartan 100 mg
Baseline and 10 hours postdose

The augmentation index (AIx) is defined as the ratio of augmentation (Δ P) to central pulse pressure and expressed as percent. AIx = (ΔP/PP) x 100, where P = pressure and PP = Pulse Pressure. A mathematical transfer function translated the peripheral wave form into a central waveform using an FDA approved process based on directly recorded arterial pressure values. The mean AIx for each subject was estimated as a time-weighted average over the 10-hour post dose observation period and expressed as a change from baseline.
