Changes in HbA1c and weight, and treatment persistence, over the 18 months following initiation of second-line therapy in patients with type 2 diabetes: results from the United Kingdom Clinical Practice Research Datalink.

BACKGROUND: Intensification of metformin monotherapy with additional glucose-lowering drugs is often required in patients with type 2 diabetes (T2D). This study evaluated changes in HbA1c and weight, as well as treatment persistence, associated with different second-line therapies used in UK clinical practice. METHODS: The UK Clinical Practice Research Datalink was used to identify patients with T2D who initiated second-line therapy after metformin monotherapy between 1 August 2013 and 14 June 2016. Treatment persistence and changes in HbA1c and weight were assessed at 6-month intervals up to 18 months. RESULTS: In total, 9097 patients (mean age 61.2 years, 57.2% men, mean [standard deviation] HbA1c 9.0% [1.8]/ 75 mmol/mol [19.7]) were included in the analysis, with a median 2.3 years between initiating metformin monotherapy and initiating second-line therapy. Patients were stratified according to second-line therapy: metformin in combination with sulfonylurea (SU; n = 4655 [51.2%]), a dipeptidyl peptidase-4 inhibitor (DPP-4 inhibitor; n = 2899 [31.9%]), or a sodium-glucose cotransporter-2 inhibitor (SGLT-2 inhibitor; n = 441 [4.9%]) or other therapies (all other second-line treatments; n = 1102 [12.1%]). At 18 months, the cumulative proportion of patients changing treatment was lowest for those who received metformin plus an SGLT-2 inhibitor (42.3%), followed by patients on metformin plus SU or metformin plus a DPP-4 inhibitor (46.8%). HbA1c reductions were seen with all second-line therapies, with an overall mean (standard error) reduction of -1.23% (0.05)/-13.4 mmol/mol (0.5). Changes were directly, but not linearly, related to baseline HbA1c and were greater in those with higher HbA1c at baseline. Weight loss from baseline was greatest in patients treated with metformin plus either an SGLT-2 inhibitor (-4.2 kg) or a DPP-4 inhibitor (-1.5 kg). The highest proportion of patients who achieved the composite outcome of HbA1c reduction ≥ 0.5%, body weight loss ≥ 2.0 kg and treatment persistence for 18 months was observed in those receiving metformin plus an SGLT-2 inhibitor (36.5%). CONCLUSIONS: In this population-based cohort, all second-line therapies added to metformin monotherapy improved glycaemic control, but the lowest treatment change/discontinuation rate and most sustained weight loss was seen with patients receiving metformin plus an SGLT-2 inhibitor

HbA_1c trajectories over 3 years in people with type 2 diabetes starting second-line glucose-lowering therapy: The prospective global DISCOVER study.

AimTo identify distinct glycated haemoglobin (HbA1c ) trajectories in people with type 2 diabetes (T2D) starting second-line glucose-lowering therapy.Materials and methodsDISCOVER was a 3-year observational study of individuals with T2D beginning second-line glucose-lowering therapy. Data were collected at initiation of second-line treatment (baseline) and at 6, 12, 24 and 36 months. Latent class growth modelling was used to identify groups with distinct HbA1c trajectories.ResultsAfter exclusions, 9295 participants were assessed. Four distinct HbA1c trajectories were identified. Mean HbA1c levels decreased between baseline and 6 months in all groups; 72.4% of participants showed stable good levels of glycaemic control over the remainder of follow-up, 18.0% showed stable moderate levels of glycaemic control and 2.9% showed stable poor levels of glycaemic control. Only 6.7% of participants showed highly improved glycaemic control at month 6 and stable control over the rest of follow-up. For all groups, dual oral therapy use decreased over time, compensated for by the increasing use of other treatment regimens. Use of injectable agents increased over time in groups with moderate and poor glycaemic control. Logistic regression models suggested that participants from high-income countries were more likely to be in the stable good trajectory group.ConclusionsMost people receiving second-line glucose-lowering treatment in this global cohort achieved stable good or highly improved long-term glycaemic control. One-fifth of participants showed moderate or poor glycaemic control during follow-up. Further large-scale studies are required to characterize possible factors associated with patterns of glycaemic control to inform personalized diabetes treatment.

Treatment patterns and glycated haemoglobin levels over 36 months in individuals with type 2 diabetes initiating second-line glucose-lowering therapy: The global DISCOVER study

Aims: To describe glucose-lowering treatment regimens and glycated haemoglobin (HbA1c) trajectories in individuals with type 2 diabetes (T2D) over 36 months of follow-up from the start of second-line therapy.  Materials and Methods: This data analysis from the 3-year, observational DISCOVER study programme included 14 687 participants from 37 countries with T2D initiating second-line glucose-lowering therapy. Treatment and HbA1c data were collected at baseline (start of second-line therapy) and at 6, 12, 24 and 36 months. Treatment regimen changes over follow-up were analysed using the McNemar test, with carry-forward imputation for intermediate missing values.  Results: A total of 11 592 participants had treatment data at baseline and 36 months, and 11 882 had HbA1c data at baseline. At baseline and 36 months, respectively, rates of oral monotherapy use were 12.1% and 12.4% (P = 0.22), rates of dual oral therapy use were 63.4% and 47.6% (P Conclusions: Dual oral therapy was the most common treatment regimen at the start of second-line treatment, and over half of the participants remained on the same treatment during follow-up.</p

Factors associated with weight loss in people with overweight or obesity living with type 2 diabetes mellitus: Insights from the global DISCOVER study

Aims To estimate real-world change in weight over 3 years and the factors influencing it in participants who are overweight and live with type 2 diabetes. Materials and Methods DISCOVER is a multinational prospective observational study that enrolled participants with type 2 diabetes between December 2014 and June 2016 at the time of initiation of a second-line glucose-lowering medication (GLM). Demographic, anthropometric, and quality-of-life data were collected at baseline, and after 6, 12, 24 and 36 months of follow-up. Using a hierarchical, repeated-measures linear regression model, we examined factors associated with weight change over time. Results Of 10 675 participants with type 2 diabetes who were overweight/obese (mean age 57.1 ± 11.1 years, 46% women), 21% lost ≥5% weight over 3 years, which was associated with modestly improved physical and mental health. Advancing age, female sex, and higher baseline weight were associated with weight loss. Most importantly, the type of GLM prescribed at previous visit had the strongest impact on weight change over time independent of participant factors, with use of a sodium-glucose cotransporter-2 inhibitor or glucagon-like peptide-1 receptor agonist associated with 1.0% weight loss versus a 0.6% weight gain with sulphonylureas, thiazolidinediones, meglitinides or insulin. Conclusion In this large contemporary prospective study, approximately one in five participants with early-stage type 2 diabetes and overweight/obesity lost ≥5% weight over 3 years. The type of GLM has the most impact on weight loss over time, highlighting the need for a careful selection of agents that takes baseline weight into consideration.</p
