Addition Of Glucagon-like Peptide-1 Receptor Agonists Research Articles

Incretins beyond type 2 diabetes.

Incretin-based therapies, in particular glucagon-like peptide-1 (GLP-1) receptor agonists, have been evaluated in other forms of diabetes, but randomised controlled trials are mainly limited to people living with type 1 diabetes. In this review we present the evidence issuing from these trials and discuss their clinical implications as well as the difficulties in interpreting the data. In type 1 diabetes, the addition of GLP-1 receptor agonists to intensive insulin therapy lowers weight and required insulin doses compared with placebo, but the effects on glucose control (HbA1c, risk of hypoglycaemia) are dependent on the different study protocols. Side effects are limited to the gastrointestinal complaints of nausea, vomiting and diarrhoea. We briefly discuss the potential for using GLP-1 receptor agonists as (adjunct) therapies in other forms of diabetes, where the evidence to date is scarce.

313-OR: The Efficacy and Safety of Glucagon-Like-Peptide-1 Agonists in Patients with Familial Partial Lipodystrophy

Familial partial lipodystrophy (FPLD) syndromes are a rare group of conditions with abnormal fat distribution and deposition of fat in ectopic tissues such as liver and muscle, leading to challenging metabolic abnormalities. Glucagon-like peptide-1 receptor agonists (GLP1R-A) are used for management of other metabolic dysfunction, but their efficacy in FPLD syndromes is not known. In this retrospective EMR review, we evaluate the effect of GLP1R-A for DM management in patients with FPLD for whom there are no approved treatments in the US. We collected data from 17 patients with FPLD (age 58 ± 12; 76.47 % females) and 17 patients with type 2 DM (age 58 ± 13; 71% females) before and 6 months after starting GLP1R-A. Only cases where the sole change was the addition of GLP1R-A were included in the analyses. Reduction in weight (p=0.002), BMI (p=0.001), HbA1c (p=0.02), and fasting glucose (p=0.04) (Figure 1A-D) were observed in patients with FPLD. Only the change in triglycerides after six months of treatment was greater in patients with FPLD compared to patients with DM (p=0.02, 95%CI: 13.6 to 215.8) (Figure 1E). Overall, there were no differences in changes in other parameters, and no serious events were reported. However, we observed acute pancreatitis in two cases with FPLD with longer therapy. Our study demonstrates the relative safety and effectiveness of GLP1R-A in patients with FPLD for the first time. Disclosure S.K.Imam: None. M.C.Foss-freitas: None. R.Meral: None.

Primary Occurrence of Cardiovascular Events After Adding Sodium-Glucose Cotransporter-2 Inhibitors or Glucagon-like Peptide-1 Receptor Agonists Compared With Dipeptidyl Peptidase-4 Inhibitors: A Cohort Study in Veterans With Diabetes.

The effectiveness of glucagon-like peptide-1 receptor agonists (GLP1RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) in preventing major adverse cardiac events (MACE) is uncertain for those without preexisting cardiovascular disease. To test the hypothesis that MACE incidence was lower with the addition of GLP1RA or SGLT2i compared with dipeptidyl peptidase-4 inhibitors (DPP4i) for primary cardiovascular prevention. Retrospective cohort study of U.S. veterans from 2001 to 2019. Veterans aged 18 years or older receiving care from the Veterans Health Administration, with data linkage to Medicare, Medicaid, and the National Death Index. Veterans adding GLP1RA, SGLT2i, or DPP4i onto metformin, sulfonylurea, or insulin treatment alone or in combination. Episodes were stratified by history of cardiovascular disease. Study outcomes were MACE (acute myocardial infarction, stroke, or cardiovascular death) and heart failure (HF) hospitalization. Cox models compared the outcome between medication groups using pairwise comparisons in a weighted cohort adjusted for covariates. The cohort included 28 759 GLP1RA versus 28 628 DPP4i weighted pairs and 21 200 SGLT2i versus 21 170 DPP4i weighted pairs. Median age was 67 years, and diabetes duration was 8.5 years. Glucagon-like peptide-1 receptor agonists were associated with lower MACE and HF versus DPP4i (adjusted hazard ratio [aHR], 0.82 [95% CI, 0.72 to 0.94]), yielding an adjusted risk difference (aRD) of 3.2 events (CI, 1.1 to 5.0) per 1000 person-years. Sodium-glucose cotransporter-2 inhibitors were not associated with MACE and HF (aHR, 0.91 [CI, 0.78 to 1.08]; aRD, 1.28 [-1.12 to 3.32]) compared with DPP4i. Residual confounding; use of DPP4i, GLP1RA, and SGLT2i as first-line therapies were not examined. The addition of GLP1RA was associated with primary reductions of MACE and HF hospitalization compared with DPP4i use; SGLT2i addition was not associated with primary MACE prevention.

Insulin plus incretin: A glucose-lowering strategy for type 2-diabetes.

There are many advantages of combining incretin therapy [glucagon-like peptide-1 (GLP-1) receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors] with insulin therapy as a glucose-lowering strategy in type 2 diabetes. One important advantage is the complementary mode of the mechanistic action of incretin and insulin therapy. Another advantage is the reduction in risk of hypoglycemia and weight gain when adding incretin therapy to insulin. Several clinical trials have studied the addition of GLP-1 receptor agonists [exenatide BID (twice daily), lixisenatide, albiglutide] or DPP-4 inhibitors (vildagliptin, sitagliptin, saxagliptin, alogliptin, linagliptin) to ongoing insulin therapy or adding insulin to ongoing therapy with a GLP-1 receptor agonist (liraglutide). These studies show improved glycemia in the presence of limited risk for hypoglycemia and weight gain with the combination of incretin therapy with insulin. This article reviews the background and clinical studies on this combination.

Enhancing treatment success with incretin-based therapies: A comprehensive approach to the patient with diabetes

Adding glucagon-like peptide-1 (GLP-1) receptor agonists to insulin therapy for patients with type 2 diabetes mellitus (T2DM): why and how patients with T2DM who progress to insulin therapy usually do so by starting with a single injection of a long-acting insulin analog, added to oral anti-diabetic drugs. Long-acting insulin analogs provide basal insulin coverage and address elevated fasting blood glucose levels. Because of the near universal efficacy of insulin, such approaches are almost always successful in lowering blood glucose levels, but may not bring patients to goal because they do not address postprandial hyperglycemia. The approach to postprandial hyperglycemia has typically been to add doses of rapid-acting insulin analogs before meals. However, this may increase the risk of hypoglycemia and weight gain, and may not be acceptable to patients both in terms of patient tolerability and adherence. New approaches include the addition of GLP-1 receptor agonists to insulin in patients with uncontrolled T2DM. This article reviews the data and the clinical context of such action with respect to issues of glycemic efficacy, patient tolerability, and safety.
