About

Phase 1 basket trial including 2 open-label single-arm cohorts: REPAIR CKD cohort and REPAIR Dialysis cohort. Open label colchicine 0.3 mg daily for 8 weeks followed, in patients who tolerated the 0.3 mg dose, by forced titration to 0.6 mg daily for 8 weeks.

Full description

The REPAIR CKD cohort will enroll 100 patients with chronic kidney disease not requiring dialysis. The REPAIR Dialysis cohort will enroll 100 patients with chronic kidney disease requiring chronic maintenance dialysis. Each participant will be followed for up to 17 weeks, to determine among adults with severe chronic kidney disease not requiring dialysis and (separately) in those requiring dialysis, the proportion who, over 8 weeks of treatment, discontinue colchicine 1) 0.3 mg daily and 2) 0.6 mg daily.
