Summary Background Two glucagon-like peptide-1 (GLP-1) receptor agonists reduced renal outcomes in people with type 2 diabetes at risk for cardiovascular disease. We assessed the long-term effect of the GLP-1 receptor agonist dulaglutide on renal outcomes in an exploratory analysis of the REWIND trial of the effect of dulaglutide on cardiovascular disease. Methods REWIND was a multicentre, randomised, double-blind, placebo-controlled trial at 371 sites in 24 countries. Men and women aged at least 50 years with type 2 diabetes who had either a previous cardiovascular event or cardiovascular risk factors were randomly assigned (1:1) to either weekly subcutaneous injection of dulaglutide (1·5 mg) or placebo and followed up at least every 6 months for outcomes. Urinary albumin-to-creatinine ratios (UACRs) and estimated glomerular filtration rates (eGFRs) were estimated from urine and serum values measured in local laboratories every 12 months. The primary outcome (first occurrence of the composite endpoint of non-fatal myocardial infarction, non-fatal stroke, or death from cardiovascular causes), secondary outcomes (including a composite microvascular outcome), and safety outcomes of this trial have been reported elsewhere. In this exploratory analysis, we investigate the renal component of the composite microvascular outcome, defined as the first occurrence of new macroalbuminuria (UACR >33·9 mg/mmol), a sustained decline in eGFR of 30% or more from baseline, or chronic renal replacement therapy. Analyses were by intention to treat. This trial is registered with , number NCT01394952 . Findings Between Aug 18, 2011, and Aug 14, 2013, 9901 participants were enrolled and randomly assigned to receive dulaglutide (n=4949) or placebo (n=4952). At baseline, 791 (7·9%) had macroalbuminuria and mean eGFR was 76·9 mL/min per 1·73 m 2 (SD 22·7). During a median follow-up of 5·4 years (IQR 5·1–5·9) comprising 51 820 person-years, the renal outcome developed in 848 (17·1%) participants at an incidence rate of 3·5 per 100 person-years in the dulaglutide group and in 970 (19·6%) participants at an incidence rate of 4·1 per 100 person-years in the placebo group (hazard ratio [HR] 0·85, 95% CI 0·77–0·93; p=0·0004). The clearest effect was for new macroalbuminuria (HR 0·77, 95% CI 0·68–0·87; p Interpretation Long-term use of dulaglutide was associated with reduced composite renal outcomes in people with type 2 diabetes.

Background: Glucagon-like peptide 1 receptor agonists (GLP1-RA) and sodium-glucose contransporter-2 inhibitors (SGLT2i) have emerged as two new classes of antihyperglycemic agents that also reduce cardiovascular risk. The relative benefits in patients with and without established atherosclerotic cardiovascular disease (ASCVD) for different outcomes with these classes of drugs remain undefined. Methods: We performed a systematic review and trial-level meta-analysis of GLP1-RA and SGLT2i cardiovas...

Summary Background Many antihyperglycaemic drugs, including insulin, are primarily cleared by the kidneys, restricting treatment options for patients with kidney disease. Dulaglutide is a long-acting glucagon-like peptide-1 receptor agonist that is not cleared by the kidneys, and confers a lower risk of hypoglycaemia than does insulin. We assessed the efficacy and safety of dulaglutide in patients with type 2 diabetes and moderate-to-severe chronic kidney disease. Methods AWARD-7 was a multicent...

Approximately 20% to 40% of patients with type 1 or type 2 diabetes mellitus develop diabetic kidney disease. This is a clinical syndrome characterized by persistent albuminuria (> 300 mg/24 h, or > 300 mg/g creatinine), a relentless decline in glomerular filtration rate (GFR), raised arterial blood pressure, and enhanced cardiovascular morbidity and mortality. There is a characteristic histopathology. In classical diabetic nephropathy, the first clinical sign is moderately increased urine album...

Abstract Glucagon like peptide-1 receptor agonists and dipeptidyl peptidase-IV inhibitors (collectively termed incretin-based therapies) represent two of the most widely used classes of antidiabetic drugs. These compounds exert their beneficial effects on carbohydrate metabolism through the activation of specific glucagon like peptide-1 receptors in various organs. Accumulating evidence suggests that glucagon like peptide-1 receptor agonists and dipeptidyl peptidase-IV inhibitors also affect ren...

A 72-year-old man had type 2 diabetes (T2D) that had been diagnosed at 54 years old. Macroalbuminuria was first detected at age 64. While his HbA1c had been kept below 7%, his estimated glomerular filtration rate (eGFR) was declining rapidly. At 70 years old, his eGFR dropped below 50 ml/min/1.73 m(2). A renal biopsy revealed diabetic nephropathy. sodium glucose transporter 2 inhibitors (SGLT2i)/glucagon-like peptide-1 receptor agonists (GLP-1RA) combination therapy substantially improved his eG...

This review examines the available literature on the effect of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on renal outcomes in type 2 diabetes mellitus. Diabetes is an important cause of end-stage renal disease requiring renal replacement therapy, and diabetic kidney disease is an independent risk factor for cardiovascular disease (CVD). GLP-1RAs are proven to be safe in terms of CVD, and some of them have been shown to have a beneficial effect on cardiovascular outcomes. The effect of...

25 years ago, the future of treating obesity and diabetes focused on end organs known to be involved in energy balance and glucose regulation, including the brain, muscle, adipose tissue, and pancreas. Today, the most effective therapies are focused around the gut. This includes surgical options, such as vertical sleeve gastrectomy and Roux-en-Y gastric bypass, that can produce sustained weight loss and diabetes remission but also extends to pharmacological treatments that simulate or amplify va...

Abstract Chronic kidney disease (CKD) is an important public health concern in developed countries both because of the number of people affected as well as the high costs of care when prevention strategies are not effectively implemented. Prevention should start at the governance level with institution of multi-sectoral polices supporting the sustainable development goals and ensuring safe and healthy environments. Primordial prevention of CKD can be achieved through implementation of measures t...

In 2008, the US Food and Drug Administration provided guidance for the evaluation of the cardiovascular safety of antidiabetes drugs. The newer antidiabetes drugs, approved after 2008, were therefore evaluated in long-term cardiovascular outcome trials, designed and powered for the assessment of cardiovascular safety. Accordingly, the primary endpoint of these trials was a cardiac composite endpoint. Since 2008, the data from various cardiovascular outcome trials have been reported, including SA...
