Alport Nephropathy
Conditions
Brief summary
This biomarker study is a follow-up to CPLATFRM2201. The goal of CBASICHR0005 is to collect another urine sample, interval clinical information, and an optional DNA sample from as many of the original 80 patients as possible. This new information will transform the data obtained in PLATFRM2201 from a cross-section to a temporal profile, which will (a) further enable the identification of biomarkers predictive of faster progression, and (b) satisfy the FDA's recommendation to perform natural history studies in rare diseases.
