- New post-hoc analysis of PARADIGM-HF data demonstrates Entresto lowered levels of HbA1c (a measure of glycemic control) by 0.26% vs. 0.16% for ACE-inhibitor enalapril in heart failure with reduced ejection fraction (HFrEF) patients who also had diabetes
- New use of insulin was also reduced by 29% among patients taking Entresto compared to enalapril-treated patients
- Up to 40% of HFrEF patients have diabetes, which is associated with worse cardiovascular outcomes
- New analysis presented today at the American College of Cardiology (ACC) Annual Scientific Session and published in The Lancet Diabetes & Endocrinology
- Novartis announced today results of a new post-hoc analysis in a subgroup of patients with reduced ejection fraction heart failure (HFrEF) and diabetes suggesting that Entresto (sacubitril/valsartan) tablets improved glycemic control, as assessed by hemoglobin A1c (HbA1c) testing, compared to ACE-inhibitor enalapril. HFrEF is also known as systolic heart failure (HF) . Entresto is indicated to reduce the risk of cardiovascular (CV) death and hospitalization for HF in patients with chronic HF (NYHA Class II-IV) and reduced ejection fraction. It is not indicated to treat diabetes.
Entresto lowered HbA1c levels - a measure of average blood glucose levels for the past two to three months - after one year of treatment for HF, and this effect was sustained over three years of study follow-up. In the analysis, new use of insulin therapy or oral diabetes agents was also reduced in the Entresto group. The findings are based on data from PARADIGM-HF, the largest clinical trial ever conducted in HF , and are simultaneously being presented today at the American College of Cardiology (ACC) 66th Annual Scientific Session & Expo in Washington, D.C. and published in The Lancet Diabetes & Endocrinology.
"Diabetes is a major risk factor in heart failure and is strongly linked to progression of the disease, putting heart failure patients at increased risk of hospitalization and death," said Scott Solomon, MD, Director of Noninvasive Cardiology, Brigham and Women’s Hospital, Professor of Medicine, Harvard Medical School, and senior author of the publication. "This analysis suggests that, in addition to the proven heart failure benefits demonstrated in PARADIGM-HF, Entresto may also help tighten glycemic control among heart failure patients with diabetes."
An analysis was conducted of 3,778 HFrEF patients in the PARADIGM-HF trial who were diagnosed with diabetes or had a baseline HbA1c >=6.5% without a reported diagnosis at screening (98% of patients assessed had type 2 diabetes). The investigators compared the effects of Entresto vs. enalapril on glycemic control by measuring patients’ HbA1c levels at screening and at one-, two-, and three-year follow-up visits, and by evaluating patients’ initiation of oral antihyperglycemic or insulin therapy during the study.
This post-hoc analysis found that Entresto decreased HbA1c levels by 0.26% during the first year of follow-up, compared to a 0.16% reduction with enalapril (p=0.0023) . Over three years, HbA1c levels remained persistently lower in patients treated with Entresto compared to enalapril, with an overall reduction of 0.14% (95% CI [0.06, 0.23]; p=0.0055) . In addition, 29% fewer Entresto-treated patients initiated insulin therapy to achieve glycemic control (114 (7%) vs. 153 (10%) patients, HR 0.71, 95% CI, 0.56-0.90; p=0.0052) . Entresto was shown to reduce the risk of CV death or HF hospitalization compared with enalapril among patients with or without diabetes at baseline , , .
"These results show that in addition to its compelling cardiovascular efficacy, Entresto may have important metabolic benefits for HFrEF patients with diabetes," said Vasant Narasimhan, Global Head, Drug Development and Chief Medical Officer, Novartis. "We are excited about these results and committed to improving our understanding of the benefits of Entresto in different heart failure patient populations."
About Heart Failure
Heart failure (HF) is a debilitating and life-threatening condition, which impacts more than 60 million people worldwide. It is the leading cause of hospitalization in people over the age of 65 , . About half of people with HF have heart failure with reduced ejection fraction (HFrEF) . Reduced ejection fraction means the heart does not contract with enough force, so less blood is pumped out. HF presents a major and growing health-economic burden that currently costs the world economy $108 billion every year, which accounts for both direct and indirect costs , .
Novartis has established the largest global clinical program in the HF disease area across the pharma industry to date, FortiHFy, comprising more than 40 active or planned clinical studies designed to generate an array of additional data on symptom reduction, efficacy, quality of life benefits and real world evidence with Entresto, as well as to extend understanding of heart failure.
Entresto is a twice-a-day medicine that reduces the strain on the failing heart. It does this by enhancing the protective neurohormonal systems (natriuretic peptide system) while simultaneously inhibiting the harmful effects of the overactive renin-angiotensin-aldosterone system (RAAS) , . Other HF medicines only block the harmful effects of the overactive RAAS. Entresto contains the neprilysin inhibitor sacubitril and the angiotensin receptor blocker (ARB) valsartan.
In Europe, Entresto is indicated in adult patients for the treatment of symptomatic chronic heart failure with reduced ejection fraction (HFrEF). In the United States, Entresto is indicated to reduce the risk of cardiovascular (CV) death and hospitalization for HF in patients with chronic HF (NYHA class II-IV) and reduced ejection fraction. Entresto is usually administered in conjunction with other HF therapies, in place of an ACE inhibitor or other angiotensin receptor blocker (ARB). Approved indications may vary depending upon the individual country.
PARADIGM-HF was a randomized, double-blind, Phase III study evaluating the efficacy and safety profile of Entresto versus enalapril (a widely studied ACE inhibitor) in 8,442 patients with HFrEF , . The baseline characteristics showed the patients enrolled were typical HFrEF patients with NYHA Class II-IV heart failure. PARADIGM-HF was specifically designed to see if Entresto could decrease CV mortality by at least 15% vs. enalapril. Patients received Entresto or enalapril in addition to current best treatment regimen. The primary endpoint was a composite of time to first occurrence of either CV death or HF hospitalization, and is the largest HF study ever done.
