In the DAPA-CKD trial, treatment with the SGLT2 inhibitor dapagliflozin (Farxiga) cut the incidence of substantially worsened chronic kidney disease by an average of 39% compared with placebo when added to standard treatment, with a number needed to treat of 19 to prevent one primary outcome event after a median of 2.4 years.
The level of benefit was similar in both the one-third of enrolled patients without diabetes and in the two-thirds with diabetes, showing a statistically significant 50% cut in the primary endpoint among patients without diabetes, Hiddo J.L. Heerspink, MD, reported at the virtual annual congress of the European Society of Cardiology.
“We found that dapagliflozin delayed the initiation of dialysis, and reduced the number of deaths,” regardless of diabetes status, Dr. Heerspink, of University Medical Centre Groningen, the Netherlands, said during a press conference. “DAPA-CKD trial has shown dapagliflozin’s potential as a long-awaited new treatment for patients with chronic kidney disease.”
This finding ushers in a “completely new era in chronic kidney disease management,” said Janani Rangaswami, MD, a nephrologist and cardiorenal syndrome specialist at Einstein Medical Center in Philadelphia. “It’s good news” for these patients.
The results showed that dapagliflozin is the first “game changing” drug for chronic kidney disease in 2 decades, following the introduction of angiotensin converting enzyme inhibitors and angiotensin receptor blockers, she said in an interview. And given the consistency of the findings with the results from several other studies that documented meaningful renal protection by several different SGLT2 inhibitors, the results from this single trial also convincingly establish dapagliflozin as a standard-of-care agent to use on the types of patients the study enrolled, she said in an interview.
Representing many real-world patients
The DAPA-CKD trial enrolled 4,304 patients with albuminuria based on having a urinary albumin-to-creatinine ratio of at least 200 mg/g, and an estimated glomerular filtration rate (eGFR) of 25-75 mL/min per 1.73 m2 (with 90% of patients having an eGFR of less than 60 mL/min per 1.73 m2), and 97% were on treatment with a renin-angiotensin system–blocking drug. The primary endpoint was the combined rate of a drop in eGFR of at least 50% from baseline, progression to end stage renal disease, or renal or cardiovascular death; the between-group difference in this composite was driven primarily by both preserved eGFR and by prevention of end stage renal disease.
This represents both an appropriate target population, and meaningful endpoints, Dr. Rangaswami said. The study was “very representative of who we see in real-world practice,” a group that likely includes “hundreds of thousands” of U.S. patients with nondiabetic chronic kidney disease, she estimated.
Another notable finding was that 14% of the enrolled patients had eGFR values at baseline of 25-29 mL/min per 1.73 m2, pegging them as having stage 4 chronic kidney disease, and the median baseline eGFR was 43 mL/min per 1.73 m2, but dapagliflozin treatment was as safe and effective in these patients as it was in enrolled patients with a higher level of retained renal activity. This experience should give clinicians greater confidence about using dapagliflozin and other drugs in the sodium-glucose cotransporter (SGLT) 2 inhibitor class in patients with substantially depressed renal function, Dr. Rangaswami said.
“We now need to be more proactive about treating patients with more advanced kidney disease who can still benefit” from dapagliflozin treatment. “The sooner you intervene the better,” to slow further progression, but the new findings show “benefit even when treating patients with lower eGFRs. There is still hope to prevent or delay dialysis.”
A heart-kidney connection
Dapagliflozin treatment also cut all-cause mortality by a statistically significant, relative 31%, and another secondary-endpoint analysis showed a statistically significant 29% relative reduction in the rate of cardiovascular death or heart failure hospitalization, a benefit seen consistently in several prior studies of SGLT2 inhibitors, but possibly unexpected here because enrolled patients underwent no selection for a history of heart failure or any other cardiovascular disease. But the finding shouldn’t surprise, because “chronic kidney disease is an independent risk factor for cardiovascular disease across the board, and especially for heart failure,” noted Dr. Rangaswami.
“Heart and kidney disease is one big spectrum,” and the collected experience of several trials that have now proven the efficacy of SGLT2 inhibitors among patients with heart failure with reduced ejection fraction or with chronic kidney disease, regardless of their glycemic control, shows how broadly this drug class can benefit patients across the breadth of this spectrum, she said.
