Urine dipstick must be =< 0-1+ within 2 weeks (14 days) of randomization; if urine dipstick result is > 1+, a calculation of urine protein creatinine (UPC) ratio is required; patients must have a UPC ratio < 1.0 to participate in the study; NOTE: UPC ratio of spot urine is an estimation of the 24 urine protein excretion [clinicaltrials_resource:1274dfa8d3d48661b153f1762e195db5]
