Effectiveness and safety of insulin glargine Gla-300 in insulin-naïve type 2 diabetes subjects in a real-life setting-the GOAL_RO trial

Real-World Study on Effectiveness of Insulin Glargine U300 After Oral Antidiabetic Drug Failure in Patients with Type 2 Diabetes in the Gulf Region

INTRODUCTION

The effectiveness and safety of long-acting insulin glargine U300 (Gla-300), in patients with type 2 diabetes mellitus (T2DM) requiring insulin, has not been reported in the Gulf region.

METHODS

Insulin-naïve patients with T2DM, uncontrolled on OADs, and prescribed Gla-300 were followed up in a 12-month prospective observational study. Gla-300 was titrated to glycemic targets. The primary endpoint (achieving glycemic targets) was evaluated at month 6 of treatment. The need for treatment intensification, safety, and patient-reported outcomes (PRO) were also reported.

RESULTS

The study included 412 patients (61.7% men; age 52.2 ± 11.1 years and T2DM duration 10.7 ± 6.8 years). Almost 50% were on more than 3 OADs, mostly biguanides, sulfonylureas, and dipeptidyl-peptidase-4 inhibitors. Baseline HbA1c level was 9.2% ± 1.1% and targets were set at 6.9% ± 0.4%. Baseline fasting plasma glucose was 11.5 ± 3.8 mmol/l. Fifty-seven patients (13.8%) achieved glycemic targets at month 6, hindered by baseline HbA1c ≥ 10%, frequent co-morbidities, older age, suburban/rural residence, and full-time employment. Levels of HbA1c dropped progressively by 0.96% ± 0.07% (month 3), 1.29% ± 0.08% (month 6), and 1.76% ± 0.06% (month 12). Gla-300 dose was 17.0 ± 9.0 IU/day at baseline, 24.6 ± 9.6 IU/day at month 3, 28.5 ± 9.9 IU/day at month 6, and 30.7 ± 10.7 IU/day at month 12. Three patients experienced non-severe hypoglycemia and a slight decrease in body weight and PROs improved.

CONCLUSIONS

In the Gulf, Gla-300 in patients with T2DM uncontrolled on OADs improved glycemic control, with low rates of hypoglycemia and improved PROs. Gla-300 dose up-titration from baseline to month 6 did not, however, result in a vast proportion of patients achieving their pre-determined HbA1c targets.

Does Gender Influence the Effectiveness and Safety of Insulin Glargine 300 U/ml in Patients with Uncontrolled Type 2 Diabetes? Results from the REALI European Pooled Analysis

INTRODUCTION

Gender differences in risk factors and treatment outcomes for type 2 diabetes mellitus (T2DM) may exist. We used the REALI European database to investigate whether there were gender-specific differences in baseline characteristics and clinical outcomes among patients with inadequately controlled T2DM initiated on insulin glargine 300 U/ml (Gla-300).

METHODS

Data were pooled from 14 multicentre, prospective, interventional and non-interventional studies. Impact of gender on glycaemic control, insulin dose, body weight and hypoglycaemia was evaluated after 12 and 24 weeks of Gla-300 treatment.

RESULTS

Women (N = 3857) were older than men (N = 4376) (median age, 65.0 versus 63.0 years), with greater mean body mass index (32.5 versus 31.6 kg/m²) and lower median estimated glomerular filtration rate (77.5 versus 84.0 ml/min/1.73 m²). Peripheral arterial disease and a history of myocardial infarction were more frequent in men (20.1% versus 11.7% and 12.0% versus 5.8%, respectively). At baseline, mean haemoglobin A1c (HbA1c) was 8.74% in men and 8.79% in women. Least square (LS) mean (95% CI) reduction in HbA1c from baseline to week 24 was - 1.17% (- 1.21 to - 1.13) in men and - 1.07% (- 1.11 to - 1.02) in women, resulting in a LS mean difference of - 0.10% (- 0.15 to - 0.05; p < 0.0001). At 24 weeks, 21.6% of women and 27.2% of men achieved target HbA1c of < 7.0% (p < 0.001; chi-square). Reported incidence for symptomatic (8.5% versus 8.7%) and severe (0.3% versus 0.5%) any-time-of-the-day or symptomatic (2.4% versus 1.8%) and severe (0.1% versus 0.2%) nocturnal hypoglycaemia was overall low and comparable between men and women. Changes in daily Gla-300 dose and body weight were also similar.

CONCLUSION

Despite some gender differences in baseline characteristics, Gla-300 treatment improved glycaemic control, with overall low hypoglycaemia incidences in both men and women. However, women had statistically significantly lower HbA1c reductions than men, although these differences were clinically modest.
