Primary Endpoints
Safety and efficacy
Morphologic assessment of GL-3 inclusions in the capillary endothelium (vasculature) of the kidney
Globotriaosylceramide (GL-3) Clearance in Kidney Interstitial Capillary Endothelium
Throughout study; 96 weeks

Kidney biopsies were taken at Baseline, Week 24, and Week 96 and analyzed for cellular GL-3 accumulation (inclusions) by light microscopy. Each biopsy was evaluated by pathologists for the total number of vessels with GL-3 accumulation on an inclusion severity score of 0 (none/trace), 1 (mild), 2 (moderate), and 3 (severe).

Globotriaosylceramide (GL-3) Clearance in Capillary Endothelium in the Skin
Baseline, Week 24 and Week 48

Skin biopsies were taken at Baseline, Week 24 and Week 48 and analyzed for cellular GL-3 accumulation (inclusions) by light microscopy. Each biopsy was evaluated by pathologists for the total number of vessels with GL-3 accumulation on an inclusion severity score of 0 (none/trace), 1 (mild), 2 (moderate), and 3 (severe).
