FARXIGA Significantly Reduced Hospitalization for Heart Failure or CV Death in a Broad Patient Population with Type 2 Diabetes in the Landmark DECLARE-TIMI 58 Trial

Business Wire 10-Nov-2018 4:45 PM

Fewer MACE events observed with FARXIGA vs. placebo, but this finding did not reach statistical significance

No imbalance in amputations, fractures, bladder cancer or Fournier's gangrene with FARXIGA vs. placebo

AstraZeneca today announced positive full results from the DECLARE-TIMI 58 cardiovascular (CV) outcomes trial (CVOT) for FARXIGA (dapagliflozin). The data were presented as a late-breaking abstract (#19485) at the American Heart Association (AHA) Scientific Sessions 2018 in Chicago, IL, and simultaneously published in the New England Journal of Medicine (NEJM).¹

Results from DECLARE-TIMI 58, the largest SGLT-2 inhibitor (SGLT-2i) CVOT conducted to date, including more than 17,000 patients across 33 countries, showed that FARXIGA significantly reduced the risk of hospitalization for heart failure (hHF) or CV death composite vs. placebo by 17% (4.9% vs. 5.8%; HR 0.83 [95% CI 0.73-0.95], p=0.005), one of the two primary efficacy endpoints. The reduction in hHF or CV death was consistent across the entire patient population, which included those with CV risk factors and those with established CV disease.¹ FARXIGA is not indicated to reduce the risk of CV events or hHF.

Additionally, there were fewer major adverse cardiovascular events (MACE) observed with FARXIGA for the other primary efficacy endpoint, however this did not reach statistical significance (8.8% for FARXIGA vs. 9.4% for placebo; HR 0.93 [95% CI 0.84-1.03], p=0.17).¹

DECLARE-TIMI 58 also confirmed the well-established safety profile for FARXIGA, which met the primary safety endpoint of non-inferiority vs. placebo, demonstrating no increase in the composite of MACE, defined as CV death, heart attack (myocardial infarction), or stroke.¹

Further, on other relevant safety measures, the trial showed no imbalance with FARXIGA vs. placebo in amputations (1.4% vs. 1.3%), fractures (5.3% vs. 5.1%), bladder cancer (0.3% vs. 0.5%) or Fournier's gangrene (1 case vs. 5 cases). The respective incidences of diabetic ketoacidosis (0.3% vs. 0.1%) and genital infections (0.9% vs. 0.1%) were rare.¹

Elisabeth Björk, Vice President, Head of Cardiovascular, Renal and Metabolism, Global Medicines Development, said: "These positive results are clinically relevant to the 425 million people worldwide living with diabetes, of whom those with type 2 diabetes have a two-to-five times greater risk of heart failure along with an increased risk of a heart attack or stroke. Heart failure survival rates are only 50% after five years from diagnosis, which is why these new findings are so important in broadening our understanding of how to go beyond blood glucose so we may better address this serious and often overlooked cardiovascular complication."^2-6

Although secondary endpoints were only nominally significant, the renal composite endpoint showed that FARXIGA reduced the rate of new or worsening nephropathy by 24% vs. placebo across the broad patient population studied (4.3% vs. 5.6%; HR 0.76 [95% CI 0.67-0.87]), and there were fewer all-cause mortality events with FARXIGA vs. placebo (6.2% vs. 6.6%; HR 0.93 [95% CI 0.82-1.04]).¹ FARXIGA is not indicated to reduce the risk of HF, other CV outcomes, nephropathy or all-cause mortality.

INDICATION AND LIMITATIONS OF USE FOR FARXIGA (dapagliflozin) tablets 5 mg and 10 mg

FARXIGA is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

FARXIGA is not recommended for patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis.

IMPORTANT SAFETY INFORMATION FOR FARXIGA

Contraindications

• Prior serious hypersensitivity reaction to FARXIGA
• Severe renal impairment (eGFR <30 mL/min/1.73 m²), end-stage renal disease, or patients on dialysis

Warnings and Precautions

• Hypotension: FARXIGA causes intravascular volume contraction, and symptomatic hypotension can occur. Assess and correct volume status before initiating FARXIGA in patients with impaired renal function, elderly patients, or patients on loop diuretics. Monitor for hypotension
• Ketoacidosis has been reported in patients with type 1 and type 2 diabetes receiving FARXIGA. Some cases were fatal. Assess patients who present with signs and symptoms of metabolic acidosis for ketoacidosis, regardless of blood glucose level. If suspected, discontinue FARXIGA, evaluate and treat promptly. Before initiating FARXIGA, consider risk factors for ketoacidosis. Patients on FARXIGA may require monitoring and temporary discontinuation in situations known to predispose to ketoacidosis
• Acute Kidney Injury and Impairment in Renal Function: FARXIGA causes intravascular volume contraction and renal impairment, with reports of acute kidney injury requiring hospitalization and dialysis. Consider temporarily discontinuing in settings of reduced oral intake or fluid losses. If acute kidney injury occurs, discontinue and promptly treat.FARXIGA increases serum creatinine and decreases eGFR. Elderly patients and patients with impaired renal function may be more susceptible to these changes. Before initiating FARXIGA, evaluate renal function and monitor periodically. FARXIGA is not recommended in patients with an eGFR persistently between 30 and <60 mL/min/1.73 m²
• Urosepsis and Pyelonephritis: SGLT2 inhibitors increase the risk for urinary tract infections [UTIs] and serious UTIs have been reported with FARXIGA. Evaluate for signs and symptoms of UTIs and treat promptly
• Hypoglycemia: FARXIGA can increase the risk of hypoglycemia when coadministered with insulin and insulin secretagogues. Consider lowering the dose of these agents when coadministered with FARXIGA
• Necrotizing Fasciitis of the Perineum (Fournier's Gangrene): Rare but serious, life-threatening cases have been reported in patients receiving SGLT2 inhibitors including FARXIGA. Cases have been reported in females and males. Serious outcomes have included hospitalization, surgeries, and death. Assess patients presenting with pain or tenderness, erythema, swelling in the genital or perineal area, along with fever or malaise. If suspected, institute prompt treatment and discontinue FARXIGA.
• Genital Mycotic Infections: FARXIGA increases the risk of genital mycotic infections, particularly in patients with prior genital mycotic infections. Monitor and treat appropriately
• Increases in Low-Density Lipoprotein Cholesterol (LDL-C) occur with FARXIGA. Monitor LDL-C and treat per standard of care
• Bladder cancer: An imbalance in bladder cancers was observed in clinical trials. There were too few cases to determine whether the emergence of these events is related to FARXIGA, and insufficient data to determine whether FARXIGA has an effect on pre-existing bladder tumors. FARXIGA should not be used in patients with active bladder cancer. Use with caution in patients with a history of bladder cancer
• Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with FARXIGA

Adverse Reactions

In a pool of 12 placebo-controlled studies, the most common adverse reactions (=5%) associated with FARXIGA 5 mg, 10 mg, and placebo respectively were female genital mycotic infections (8.4% vs. 6.9% vs. 1.5%), nasopharyngitis (6.6% vs. 6.3% vs. 6.2%), and urinary tract infections (5.7% vs. 4.3% vs. 3.7%).

Use in Specific Populations

• Pregnancy: Advise females of potential risk to a fetus especially during the second and third trimesters.
• Lactation: FARXIGA is not recommended when breastfeeding

About DECLARE-TIMI 58

DECLARE (Dapagliflozin Effect on Cardiovascular Events)-TIMI-58 is an AstraZeneca-sponsored, randomized, double-blinded, placebo-controlled, multicenter trial designed to evaluate the effect of FARXIGA compared with placebo on CV outcomes in adults with T2D at risk of CV events, including patients with multiple CV risk factors or established CV disease. DECLARE included more than 17,000 patients across 882 sites in 33 countries and was independently run in collaboration with academic investigators from the TIMI study group (Boston, USA) and the Hadassah Hebrew University Medical Center (Jerusalem, Israel).
