Keryx Biopharmaceuticals Inc.

Keryx Biopharmaceuticals Inc. announced top-line results from its SUN-MICRO Phase 3 clinical trial of Sulonex (sulodexide) for the treatment of diabetic nephropathy. The Company announced that this Phase 3 clinical trial failed to meet the primary objective of the study, which was to increase the proportion of patients that achieve therapeutic success at 6 months as compared to placebo over background therapy of maximal doses of ACE-inhibitors or ARBs. Therapeutic success was defined as (i) conversion from microalbuminuria to normoalbuminuria, as measured by albumin/creatinine ratio (ACR), with at least a 25% reduction in ACR relative to baseline ACR, or (ii) a 50% reduction in ACR relative to baseline ACR. In addition, in reviewing the mean changes in ACR over time, Sulonex and placebo appeared to be similar.
