Greater Combined Reductions of HbA_1c ≥ 1.0% and Body Weight Loss ≥ 5.0% or ≥ 10.0% with Orally Administered Semaglutide Versus Comparators.

ABSTRACT:

Introduction

A post hoc analysis of the PIONEER 1-5 and 8 trials assessed the clinically relevant composite endpoints of HbA_1c (glycated haemoglobin) reduction ≥ 1% and body weight loss of ≥ 5% or ≥ 10% with orally administered semaglutide versus comparators.

Methods

In the PIONEER trials, people with type 2 diabetes were randomised to orally administered semaglutide versus placebo (PIONEER 1, 4, 5 and 8), empagliflozin (PIONEER 2), sitagliptin (PIONEER 3) and liraglutide (PIONEER 4) for 26-78 weeks. This analysis assessed the proportion of people achieving an HbA_1c reduction of ≥ 1% and body weight loss of ≥ 5% at week 26 and at end of treatment, and the proportion of people achieving an HbA_1c reduction of ≥ 1% and body weight loss of ≥ 10% at end of treatment.

Results

Overall, 3506 people in PIONEER 1-5 and 8 were included. At week 26 and at end of treatment, odds of achieving the composite endpoint of an HbA_1c reduction of ≥ 1% and body weight loss of ≥ 5% were significantly greater with orally administered semaglutide 14 mg than with placebo (PIONEER 1, 4, 5 and 8; all p < 0.0001), empagliflozin 25 mg (PIONEER 2, p < 0.0001), sitagliptin 100 mg (PIONEER 3, p < 0.0001) and liraglutide 1.8 mg (PIONEER 4, p < 0.0001). Odds of achieving the composite endpoint of HbA_1c reduction of ≥ 1% and body weight loss of ≥ 10% at end of treatment were also significantly greater with orally administered semaglutide versus comparators.

Conclusion

In PIONEER 1-5 and 8, odds of achieving clinically relevant reductions in both HbA_1c and body weight were significantly greater with orally administered semaglutide versus comparators.

Project description:IntroductionThe efficacy and safety of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, were investigated in patients with type 2 diabetes (T2D) in the Peptide InnOvatioN for Early diabEtes tReatment (PIONEER) programme. The current post-hoc exploratory subgroup analyses evaluated outcomes by background medication and insulin regimen subgroups.MethodsData from patients in the PIONEER 3-5, 7 and 8 trials receiving once-daily oral semaglutide (14 mg/flexibly dosed) or a comparator (placebo, sitagliptin 100 mg or liraglutide 1.8 mg) were analysed for efficacy (glycated haemoglobin [HbA1c] and body weight changes from baseline to planned end of treatment) and safety outcomes. Patients were grouped according to background medication (metformin, sulphonylurea, thiazolidinedione, sodium-glucose cotransporter-2 inhibitor, insulin, or combinations thereof). Efficacy outcomes were analysed using the trial product estimand (which assumes that patients remained on the trial product without rescue medication use). A separate analysis by background insulin regimen (basal, premixed or basal-bolus) was done for PIONEER 8 using the treatment policy estimand (regardless of trial product discontinuation or rescue medication use). Safety outcomes were analysed descriptively for all patients.ResultsIn total, 2836 patients receiving oral semaglutide 14 mg/flexibly dosed or comparators were included. Baseline characteristics were generally similar across background medication subgroups within each trial. Diabetes duration tended to be longer in patients receiving more background medications. Greater HbA1c and body weight reductions were seen across background medication subgroups with oral semaglutide (changes from baseline: - 1.0 to - 1.5% and - 2.2 to - 5.0 kg, respectively) than with comparators (except for similar HbA1c reductions vs liraglutide). There were no statistically significant interactions by treatment and background medication subgroup for change in HbA1c or body weight except for change in HbA1c (background insulin vs insulin plus metformin) in PIONEER 8 (p = 0.0408). Changes in HbA1c and body weight were generally similar across insulin regimen subgroups, without significant treatment interactions by subgroup, and the total daily insulin dose was decreased for patients receiving oral semaglutide. The incidence of adverse events was generally similar in background medication subgroups.ConclusionOral semaglutide was effective at lowering HbA1c and body weight, regardless of background medications, and appears suitable for a broad range of patients with T2D in combination with other glucose-lowering agents.Trial registrationClinicaltrials.gov: NCT02607865 (PIONEER 3), NCT02863419 (PIONEER 4), NCT02827708 (PIONEER 5), NCT02849080 (PIONEER 7) and NCT03021187 (PIONEER 8).

Project description:Aims/hypothesisThe aim of the study was to evaluate longitudinal associations between HbA1c levels, diabetes status and subsequent cognitive decline over a 10 year follow-up period.MethodsData from wave 2 (2004-2005) to wave 7 (2014-2015) of the English Longitudinal Study of Ageing (ELSA) were analysed. Cognitive function was assessed at baseline (wave 2) and reassessed every 2 years at waves 3-7. Linear mixed models were used to evaluate longitudinal associations.ResultsThe study comprised 5189 participants (55.1% women, mean age 65.6 ± 9.4 years) with baseline HbA1c levels ranging from 15.9 to 126.3 mmol/mol (3.6-13.7%). The mean follow-up duration was 8.1 ± 2.8 years and the mean number of cognitive assessments was 4.9 ± 1.5. A 1 mmol/mol increment in HbA1c was significantly associated with an increased rate of decline in global cognitive z scores (-0.0009 SD/year, 95% CI -0.0014, -0.0003), memory z scores (-0.0005 SD/year, 95% CI -0.0009, -0.0001) and executive function z scores (-0.0008 SD/year, 95% CI -0.0013, -0.0004) after adjustment for baseline age, sex, total cholesterol, HDL-cholesterol, triacylglycerol, high-sensitivity C-reactive protein, BMI, education, marital status, depressive symptoms, current smoking, alcohol consumption, hypertension, CHD, stroke, chronic lung disease and cancer. Compared with participants with normoglycaemia, the multivariable-adjusted rate of global cognitive decline associated with prediabetes and diabetes was increased by -0.012 SD/year (95% CI -0.022, -0.002) and -0.031 SD/year (95% CI -0.046, -0.015), respectively (p for trend <0.001). Similarly, memory, executive function and orientation z scores showed an increased rate of cognitive decline with diabetes.Conclusions/interpretationSignificant longitudinal associations between HbA1c levels, diabetes status and long-term cognitive decline were observed in this study. Future studies are required to determine the effects of maintaining optimal glucose control on the rate of cognitive decline in people with diabetes.

Project description:IntroductionObesity is associated with compromised glucose metabolism. Hence, it is of interest to investigate if the lifestyle interventions used in the LIBRA-cohort, which aimed at not only weight loss, but also patient well-being, could also help obese patients improve glucose metabolism by evidence of reduced HbA1c. The aim of the study was to retrospectively investigate if patients who were referred to a lifestyle intervention for obesity, were able to alter HbA1c.Research design and methodsPatients with a BMI≥30 undergoing a 6-month lifestyle intervention, who also completed physical and mental health surveys and whose baseline and 6-month blood samples were available, were included in the analysis. For changes in HbA1c and body weight a clinically relevant change of 5≥mmom/mol and 5%≥, respectively, was chosen. Participants were divided into groups according to their baseline HbA1c level: "Diabetes": HbA1c of ≥6.5% (≥48 mmol/mol), "Prediabetes": HbA1c of 5.7% to 6.4% (39-47.99 mmol/mol) or "Normal" HbA1c <5.7% (<39 mmol/mol).Results180 patients met the stated inclusion criteria and these patients were divided into groups (median age (25th;75th quartile): Diabetes: n=47, age 54 (43;60), 51% women, Prediabetes: n=68, age 60 (50;66), 71% women and Normal: n=65, median age 61 (50;66), 85% women. Significant reductions were found in all three groups and specifically in the diabetes group HbA1c was reduced (mean [95%CI]) -5[-8;-2] mmol/mol from baseline to the end of the intervention. Furthermore, 35% of patients with prediabetes normalized their HbA1c (<39) and 30% patients with diabetes reduced their HbA1c <48. All groups had clinically relevant (≥5%) reductions in body weight (p<0.01). There was an association between body weight reduction and HbA1c reduction in the diabetes group (p<0.01). All groups reported improvements in physical health (p<0.01).ConclusionIn this retrospective cohort study, all patients achieved clinically relevant weight loss after participation in the lifestyle intervention and obese patients with diabetes achieved clinically relevant reductions in HbA1c after 6-months. More than 1/3 of patients with prediabetes normalized their HbA1c.
