Abstract
This study aimed to retrospectively compare the clinical efficacy of different types of long-acting insulin therapies-glargine U100, glargine U300, degludec, and insulin degludec/insulin aspart-among Japanese patients with type 2 diabetes after insulin use was initiated in an outpatient setting. The study consisted of 822 insulin-naïve patients in Japan who started using long-acting insulin for treatment of type 2 diabetes and continued for over 12 months. In addition, the impact of insulin type on insulin withdrawal was investigated by dividing the participants into two groups: those who achieved insulin withdrawal and those who did not, during the 12-month observation period based on a Cox proportional hazards model. As a result, HbA1c was decreased, and BMI was increased in all participants regardless of the insulin type used. A total of 185 participants succeeded in insulin withdrawal. After adjustment was made for several confounders, the positive determinant factors for withdrawal were short duration of diabetes and the choice of IDegAsp when compared with Gla100; the negative determinant factor was use of insulin secretagogues at the start of the study. In conclusion, all long-acting insulins were a powerful tool for treatment of type 2 diabetes, and patients with short duration of diabetes and/or no usage of insulin secretagogues resulted in favorable outcomes in terms of insulin withdrawal within a year in an outpatient setting. In addition, insulin degludec/insulin aspart was found to possibly be a better choice for treatment when it was compared with glargine U100 among the four types of insulin.

Insulin-GLP-1 receptor agonist relay and GLP-1 receptor agonist first regimens in individuals with type 2 diabetes: a randomized, open-label trial study. J Diabetes Investig 2022; 13:965-974. [PMID: 35034428 PMCID: PMC9153847 DOI: 10.1111/jdi.13749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 12/26/2021] [Accepted: 01/11/2022] [Indexed: 11/29/2022] Open
Abstract
Aims/Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RA) might be less effective in patients with severe hyperglycemia, because hyperglycemia downregulated the GLP‐1 receptor in an animal study. To examine this hypothesis clinically, we compared the glucose‐lowering effects of GLP‐1 receptor agonist liraglutide with and without prior glycemic control. Materials and Methods In an open‐label, parallel trial, participants with poorly controlled type 2 diabetes were recruited and randomized to receive once‐daily insulin therapy, degludec (Insulin–GLP‐1 RA relay group, mean 16.8 ± 11.4 IU/day), for 12 weeks and then liraglutide for 12 weeks or subcutaneous injections of GLP‐1 RA, liraglutide (GLP‐1 RA first group, 0.9 mg), for 24 weeks. The primary efficacy end‐points consisted of changes in the levels of fasting plasma glucose and glycated hemoglobin (HbA1c). Results The median fasting plasma glucose and HbA1c before the study were 210.0 mg/dL and 9.8%, respectively. The levels of fasting plasma glucose and HbA1c significantly decreased in the Insulin–GLP‐1 RA relay group (P < 0.001) and GLP‐1 RA first group (P < 0.001) by week 24, although no intergroup differences were observed. The reduction of HbA1c in the Insulin–GLP‐1 RA relay group tended to be larger than that in the GLP‐1 RA first group in the lowest CPR (C‐peptide immunoreactivity) quartile (P = 0.072). The adverse events consisted of gastrointestinal problems, followed by hypoglycemia. Conclusions The GLP‐1 receptor agonist is overall effective without prior glycemic control with insulin in participants with poorly controlled type 2 diabetes. However, in participants with insulinopenic type 2 diabetes, prior glycemic control with insulin might overcome glucose toxicity‐induced GLP‐1 resistance.

Clinical Characteristics of Withdrawal of Basal Insulin Therapy Among Japanese Patients with Type 2 Diabetes: A Multicenter Retrospective Observational Study. Diabetes Ther 2021; 12:1849-1860. [PMID: 34047960 PMCID: PMC8266942 DOI: 10.1007/s13300-021-01077-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 05/08/2021] [Indexed: 11/26/2022] Open
Abstract
INTRODUCTION This study aimed to examine retrospectively the clinical backgrounds of Japanese patients with type 2 diabetes (T2D) who successfully withdrew from insulin use after being started on basal insulin in an outpatient setting. METHODS The study population comprised 376 insulin-naïve patients who were started on basal insulin (glargine U100, glargine U300, or degludec) for the management of T2D and followed the treatment regimen for at least 6 months in 13 institutions in Japan. The clinical courses of the study participants were compared based on outpatient clinic medical records for the three different types of basal insulin prescribed by categorizing the participants into two groups retrospectively: those who successfully withdrew from insulin therapy and those who did not, during a 6-month observation period. The clinical determinants for insulin withdrawal were assessed using a Cox proportional hazard model. RESULTS Glycated hemoglobin was improved in all participants regardless of basal insulin type. Of the 376 study participants, 61 successfully withdrew from basal insulin therapy. After adjustment was made for several confounders, the positive determinant factors for successful withdrawal of insulin were short duration of diabetes and high body mass index at the start of study, and the negative determinant factor was use of insulin secretagogues at the start. The types of basal insulin used by the study participants were not significant determinants of successful insulin withdrawal in this study. CONCLUSIONS Use of basal insulin is a powerful option for the treatment of T2D. In patients with high BMI and/or short duration of diabetes, short-term insulin therapy is a promising strategy for the treatment of T2D before the initiation of insulin secretagogues, since such patients have the potential to successfully withdraw from basal insulin use even in an outpatient setting.

Abstract
Insulin glargine (IGlar) 100 U/mL (IGlar-100) is widely used in East Asian countries for the treatment of type 2 diabetes mellitus (T2DM) and is the gold standard of basal insulin treatment. In this review we summarize key information about clinical experience with IGlar-100 in East Asian patients with T2DM, including findings from clinical trials and postmarketing studies. We also provide recommendations and opinions on the optimal use of IGlar-100 in this population. The findings from the studies highlighted in our review indicate that IGlar-100 can be a suitable treatment option for East Asians with T2DM, from initial therapy in combination with oral antihyperglycemic medications through to different combinations and intensification models.
