About

The primary objective of this study is to determine the safety and tolerability of extended dosing with a fixed dose of GCS-100 3 mg IV push in patients with Chronic Kidney Disease (CKD).

Full description

Galectin-3 contributes to fibrosis, is elevated in patients with ESRD, and correlates with adverse outcomes (de Boer et. al., 2011, Dang et. al., 2012, Fernandes Bertocchi et. al., 2008, Henderson et. al., 2008). Animal models with genetic knockout of galectin-3 demonstrate a reduction in structural and functional deficits in the kidney (Dang et. al., 2012, Fernandes Bertocchi et. al., 2008, Henderson et. al., 2008). GCS-100 is a galectin-3 antagonist that has been shown to reduce fibrosis pre-clinically. Based on the role of galectin-3 and fibrosis in kidney disease, the Sponsor believes GCS-100 may be effective at treating patients with CKD.

This study will consist of a fixed dose of GCS-100 3mg IV push at least every 30 days for a total of 1 year with a follow-up 4 weeks after the last dose is administered.
