Priority Review for AstraZeneca’s Farxiga for Kidney Disease
FDA has granted priority review for AstraZeneca’s Farxiga (dapagliflozin) for treating new or worsening chronic kidney disease (CKD) in adults with and without Type 2 diabetes. The designation was based on clinical evidence from the DAPA-CKD Phase 3 trial showing Farxiga, on top of standard of care consisting of an ACE inhibitor or an angiotensin receptor blocker, reduced the risk of the composite of worsening of renal function or risk of cardiovascular or renal death by the 39%, compared to placebo in patients with CKD stages 2-4 and elevated urinary albumin excretion. It also significantly reduced the risk of death from any cause by 31%.
AZ says the safety and tolerability of Farxiga were consistent with the medicine’s safety profile.
Last March an independent data monitoring committee recommended the trial be stopped early, based on a determination of overwhelming efficacy.
Farxiga received FDA breakthrough therapy designation for patients with CKD with and without Type 2 diabetes. It is indicated in the U.S. as an adjunct to diet and exercise to improve glycemic control in adults with Type 2 diabetes and to reduce the risk of hospitalization for heart failure in patients with Type 2 diabetes and established cardiovascular disease or multiple cardiovascular risk factors. In 3/2020 it was approved in the U.S. to reduce the risk of cardiovascular death and hospitalization for heart failure in adults with heart failure with reduced ejection fraction with and without Type 2 diabetes. Farxiga is not indicated to reduce the worsening of renal function or death in patients with CKD.
