Article Synopsis
  • SGLT2 inhibitors like sotagliflozin show promise in improving health status for heart failure patients, but effects of SGLT1/SGLT2 inhibition remain unclear.* -
  • In the SOLOIST-WHF trial, patients taking sotagliflozin after a heart failure episode experienced a significant improvement in their Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) scores compared to those on placebo.* -
  • Overall, sotagliflozin not only reduced hospitalizations and cardiovascular deaths but also led to improved symptoms and quality of life within four months, benefiting patients regardless of their left ventricular ejection fraction.*

Aim: To study safety, efficacy and weight loss with ADO09, a co-formulation of insulin A21G and pramlintide, in type 1 diabetes.

Materials And Methods: A randomized, two-arm ambulatory 16-week study compared ADO09 with insulin lispro in 80 participants with type 1 diabetes. We compared changes of weight, glycated haemoglobin, glycaemic patterns during continuous glucose monitoring, and insulin doses at baseline and at the end of treatment.

Article Synopsis
  • Around 25% of patients with worsening heart failure (WHF) are readmitted to hospitals within 30 days after discharge.
  • The SOLOIST-WHF trial analyzed the effects of the drug sotagliflozin compared to a placebo on reducing heart failure-related deaths and events for patients who started treatment before leaving the hospital.
  • Results showed that starting sotagliflozin at discharge significantly lowered the risk of cardiovascular deaths and heart failure events at both 30 and 90 days, indicating its potential benefits for patients with type 2 diabetes post-hospitalization.

The past decade of population research for diabetes has seen a dramatic proliferation of the use of real-world data (RWD) and real-world evidence (RWE) generation from non-research settings, including both health and non-health sources, to influence decisions related to optimal diabetes care. A common attribute of these new data is that they were not collected for research purposes yet have the potential to enrich the information around the characteristics of individuals, risk factors, interventions, and health effects. This has expanded the role of subdisciplines like comparative effectiveness research and precision medicine, new quasi-experimental study designs, new research platforms like distributed data networks, and new analytic approaches for clinical prediction of prognosis or treatment response.

Aim: Pramlintide improves postprandial glucose but requires additional injections. We investigated the pharmacokinetics/pharmacodynamics, efficacy and safety of ADO09, pramlintide/insulin A21G co-formulation, in type 1 diabetes (T1D).

Materials And Methods: This double-blinded, randomized, two-period cross-over study compared prandial administration of ADO09 or insulin aspart over 24 days in T1D using either ≤40 U bolus insulin per day [low-dose group (LD), n = 28] or 40-75 U [high-dose group (HD), n = 16].

Background: The estimated glomerular filtration rate (eGFR) and the albumin-to-creatinine ratio (ACR) are risk factors for diabetes-related outcomes. A composite that captures information from both may provide a simpler way of assessing risk.

Methods: 9115 of 9901 Researching Cardiovascular Events with a Weekly Incretin in Diabetes (REWIND) participants with both an ACR and eGFR at baseline were included in this post hoc epidemiologic analysis.

Objective: To use protein biomarkers to identify people with type 2 diabetes at high risk of cardiovascular outcomes and death.

Research Design And Methods: Biobanked serum from 4,957 ELIXA (Evaluation of Lixisenatide in Acute Coronary Syndrome) trial participants was analyzed. Forward-selection Cox models identified independent protein risk factors for major adverse cardiovascular events (MACE) and death that were compared with a previously validated biomarker panel.

Aim: To assess cardiovascular, glycaemic, weight and safety outcomes of long-term treatment with dulaglutide 1.5 mg compared with placebo in patients with a baseline HbA1c of less than 7% versus 7% or higher.

Materials And Methods: Intention-to-treat analyses were performed on REWIND participants with a baseline HbA1c measurement, using Cox proportional hazards regression and mixed model for repeated measures.

Article Synopsis
  • - The study examined the link between low cognitive scores, measured by the MoCA and DSST, and the risk of cardiovascular events among participants in the REWIND trial, focusing on those with significant cognitive impairment (SCI).
  • - Out of 8,772 participants, 905 (10.3%) with SCI experienced a higher incidence of major adverse cardiovascular events (MACE) and a greater risk of stroke or death compared to those without (89.7%).
  • - Stronger associations were observed for a composite measure (SCI-GM), which remained significant even after adjusting for various risk factors, indicating that standardized cognitive impairment is a strong predictor of cardiovascular risks in individuals with type 2 diabetes.

Background Baseline and temporal changes in natriuretic peptide (NP) concentrations have strong prognostic value with regard to long-term cardiovascular risk stratification. To increase the clinical utility of NP sampling for patient management, we wanted to assess the incremental predictive value of 2 serial NP measurements compared with a single measurement and provide absolute risk estimates for cardiovascular death or heart failure hospitalization (HFH) within 6 months based on 2 serial NP measurements. Methods and Results Consecutive NP samples obtained from 5393 patients with a recent coronary event and type 2 diabetes enrolled in the ELIXA (Evaluation of Cardiovascular Outcomes in Patients With Type 2 Diabetes After Acute Coronary Syndrome During Treatment With Lixisenatide) trial were used to construct best logistic regression models with outcome of cardiovascular death or HFH (136 events).

Background: The REWIND trial demonstrated cardiovascular (CV) benefits to patients with type 2 diabetes and multiple CV risk factors or established CV disease. This exploratory analysis evaluated the degree to which the effect of dulaglutide on CV risk factors could statistically account for its effects on major adverse cardiovascular events (MACE) in the REWIND trial.

Methods: Potential mediators of established CV risk factors that were significantly reduced by dulaglutide were assessed in a post hoc analysis using repeated measures mixed models and included glycated hemoglobin (HbA1c), body weight, waist-to-hip ratio, systolic blood pressure, low-density lipoprotein (LDL), and urine albumin/creatinine ratio (UACR).

Improvement of glucose levels into the normal range can occur in some people living with diabetes, either spontaneously or after medical interventions, and in some cases can persist after withdrawal of glucose-lowering pharmacotherapy. Such sustained improvement may now be occurring more often due to newer forms of treatment. However, terminology for describing this process and objective measures for defining it are not well established, and the long-term risks versus benefits of its attainment are not well understood.

Article Synopsis
  • - The SOLOIST-WHF trial investigated the effects of sotagliflozin, a medication for patients with type 2 diabetes and heart failure, finding it reduced cardiovascular-related events by 33% compared to a placebo.
  • - The study was designed as a randomized, double-blind trial with 1,222 participants across 306 sites in 32 countries, assessing the efficacy of sotagliflozin on outcomes like days alive and out of the hospital (DAOH).
  • - Results showed while hospitalization rates were similar between both groups, those on sotagliflozin experienced fewer repeated hospitalizations and a 3% higher rate of DAOH due to a significant decrease in days lost to death.
