Multinational Observational Study to Understand Insulin Treatment Intensification: Japanese Subgroup Analysis of the MOSAIc Study.

ABSTRACT:

Introduction

MOSAIc was a multinational, non-interventional, prospective, observational cohort study designed to provide an understanding of the specific challenges associated with intensification of initial insulin therapy in patients with type 2 diabetes mellitus (T2DM). We present a sub-analysis of Japanese patients from MOSAIc, with data analyzed longitudinally over 2 years, to provide insight on how T2DM treatment is intensified.

Methods

Japanese patients with T2DM receiving any insulin therapy for at least 3 months were eligible for study inclusion. Baseline and clinical data were collected during an initial baseline visit and during four subsequent prospective visit windows (within ± 3 months) at 6, 12, 18, and 24 months. Treatment intensification was defined as addition of new insulin, increase in insulin dosage (1-unit change or 10% compared with the previous visit), increase in insulin injection frequency, and/or addition of non-insulin antihyperglycemic agents.

Results

Of 116 Japanese patients who completed the study, 50.0% (n = 58) received treatment intensification. Baseline characteristics of patients with treatment intensification included a longer duration of diabetes, higher incidence of baseline microvascular complications, and higher HbA1c compared to those without intensification. There was no significant difference in HbA1c change from baseline between the two groups at any post-baseline visit. Insulin intensification accounted for 61.2% of treatment changes, with non-insulin-related intensification accounting for 36.2% of treatment changes. An increase in insulin dose was the most frequent treatment change (51.7%), followed by the addition of new insulin (22.4%), and an increase in insulin injection frequency (6.9%).

Conclusion

Real-world data from Japanese patients with T2DM who received treatment intensification showed that an increase in insulin dose and the addition of new insulin were the most frequent treatment intensification methods. HbA1c was maintained through 2 years of treatment.

Project description:IntroductionInsulin degludec/insulin aspart (IDegAsp) provides effective glycaemic control with an acceptable safety profile in Japanese patients with diabetes in randomised clinical trials. This post-marketing surveillance study assessed long-term safety and clinical outcomes with IDegAsp in a Japanese real-world setting.MethodsMulticentre, prospective, observational, open-label, single-arm study of Japanese patients with diabetes requiring insulin therapy, who had switched to IDegAsp at their treating physician's discretion in clinical practice. One year after initiating IDegAsp, incidence of adverse events (AEs [primary endpoint]), serious AEs, adverse drug reactions (ADRs), and severe hypoglycaemia (secondary safety endpoints) were assessed in the safety analysis set (SAS). Secondary effectiveness endpoints were change from baseline in glycated haemoglobin (HbA1c) and fasting plasma glucose (FPG) in the effectiveness analysis set (EAS).ResultsOverall, 1321 patients were included (SAS, n = 1321; EAS, n = 1285); 4.2% with type 1 diabetes, 95.2% with type 2 diabetes, 0.7% with other/unknown diabetes type. In total, 204 AEs were reported in 132 patients (10.0% of the SAS), at a rate [95% confidence interval (CI)] of 16.2 events/100 patient-years of exposure (PYE) [14.0; 18.4]. By preferred term, 'hypoglycaemia' was the most frequent AE (45 events in 31 patients [2.3%]; rate [95% CI] 3.6 events/100 PYE [2.5; 4.6]). Serious AEs occurred in 4.2% of patients (rate [95% CI] 5.7 events/100 PYE [4.4; 7.0]), and ADRs in 3.1% (rate [95% CI] 4.6 reactions/100 PYE [3.4; 5.8]). Six events of severe hypoglycaemia were reported in five patients (0.4%; rate [95% CI] 0.5 events/100 PYE [0.1; 0.9]). Change from baseline to 1 year was - 0.51% and - 32.1 mg/dL for HbA1c and FPG, respectively (P < 0.0001 for both).ConclusionIn Japanese patients with diabetes, initiation of IDegAsp in real-world clinical practice was well tolerated, with no new safety signals, and associated with improved glycaemic control after 1 year.Trial registrationClinicalTrials.gov identifier, NCT02821052.

Project description:BackgroundMany patients with type 2 diabetes eventually require insulin, yet little is known about the patterns and quality of pharmacologic care received following insulin initiation. Guidelines from the American Diabetes Association and the European Association for the Study of Diabetes recommend that insulin secretagogues such as sulfonylureas be discontinued at the time of insulin initiation to reduce the risk of hypoglycemia, and that treatment be intensified if HbA1c levels remain above-target 3 months after insulin initiation.ObjectiveTo describe pharmacologic treatment patterns over time among adults initiating insulin and/or intensifying insulin treatment.DesignObservational study.SubjectsA large commercially insured population of adult patients without recorded type 1 diabetes who initiated insulin.Main measuresWe evaluated changes in non-insulin antidiabetic medication use during the 120 days immediately following insulin initiation, rates of increase in insulin dose and/or dosing frequency during the 270 days following an insulin initiation treatment period of 90 days, and rates of insulin discontinuation.Key resultsSeven thousand, nine hundred and thirty-two patients initiated insulin during 2003-2008, with the majority (61 %) initiating basal insulin only. Metformin (55 %), sulfonylureas (39 %), and thiazolidinediones (30 %) were commonly used prior to insulin initiation. Metformin was continued by 64 % of patients following mixed or mealtime insulin initiation; the continuation rate was nearly as high for sulfonylureas (58 %). Insulin dose and/or dosing frequency increased among 22.9 % of patients. Insulin was discontinued by 27 % of patients.ConclusionsWe found evidence of substantial departures from guideline-recommended pharmacotherapy. Insulin secretagogues were frequently co-prescribed with insulin. The majority of patients had no evidence of treatment intensification following insulin initiation, although this finding is difficult to interpret without HbA1c levels. While each patient's care should be individualized, our data suggest that the quality of care following insulin initiation can be improved.
