CREDENCE canagliflozin trial halted because of efficacy


The CREDENCE trial, which was investigating whether the antidiabetes drug canagliflozin (Invokana) plus standard of care could safely help prevent or slow chronic kidney disease (CKD) in patients with type 2 diabetes, has been ended early because it has already achieved prespecified efficacy criteria, Janssen announced in a press release. These criteria included risk reduction in the composite endpoint of time to dialysis or kidney transplant, doubling of serum creatinine, and renal or cardiovascular death.

In CANVAS, the cardiovascular outcomes trial for canagliflozin, treatment was linked to reductions in progression of albuminuria and the composite outcome of a sustained 40% reduction in the estimated glomerular filtration rate, the need for renal replacement therapy, or death from renal causes, compared with placebo, but those didn’t reach statistical significance.

CREDENCE (Evaluation of the Effects of Canagliflozin on Renal and Cardiovascular Outcomes in Participants With Diabetic Nephropathy) is a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial that enrolled roughly 4,400 patients with type 2 diabetes and established kidney disease who had been receiving ACE inhibitors or angiotensin II receptor blockers for at least 4 weeks prior to randomization.

The decision to halt CREDENCE came about after a review of data by the study’s independent data monitoring committee during a planned interim analysis. The resulting recommendation was based on the efficacy findings, the exact data for which have not yet been released.

Canagliflozin, a sodium-glucose transporter 2 (SGLT2) inhibitor, in conjunction with diet and exercise, can help improve glycemic control. In the context of kidney disease and type 2 diabetes, canagliflozin has been associated with increased risk of dehydration, vaginal or penile yeast infections, and amputations of all or part of the foot or leg. It has also been associated with ketoacidosis, kidney problems, hyperkalemia, hypoglycemia, and urinary tract infections.

More information can be found in the press release. Full prescribing information can be found on the Food and Drug Administration website.
