Impact of the Fasting Plasma Glucose Titration Target on the Success of Basal Insulin Titration in Insulin-Naive Patients with Type 2 Diabetes: A Systematic Analysis

ABSTRACT:

Background/Aim

We aimed to examine beneficial and adverse outcomes of basal insulin titration performed with different fasting plasma glucose (FPG) titration targets (TT).

Methods

A PubMed literature search retrieved 43 reported prospective clinical trials introducing basal insulin in 17643 insulin-naïve patients with type 2 diabetes reporting fasting plasma glucose (FPG), HbA1c, target achievement, hypoglycemic events, and insulin doses. 61 individual study arms were grouped by fasting plasma glucose titration target (TT; 1: ≤5.0 mmol/l/90 mg/dl; 2: 5.01-5.6 mmol/l/90-100 mg/dl; and 3: ≥5.61 mmol/l/101 mg/dl). Weighted means and their standard deviations were calculated for baseline and end-of-treatment FPG (primary endpoint), HbA1c, target achievement, hypoglycemic events, insulin doses, and body weight gain and compared over a duration of 31 ± 10 weeks.

Results

Achieved FPG and HbA1c at the end of the study were significantly lower (by up to 0.8 mmol/l or 0.23%, respectively) with more ambitious TTs (p < 0.0001), leading to better HbA1c target achievement with more ambitious TTs (by up to 14.6% for HbA1c ≤ 6.5%), without increasing the risk for hypoglycemic episodes.

Conclusions

Aiming for a lower FPG TT improves glycemic control without increasing the risk for hypoglycemia.

Twice-daily insulin degludec/insulin aspart provides superior fasting plasma glucose control and a reduced rate of hypoglycaemia compared with biphasic insulin aspart 30 in insulin-naive adults with Type 2 diabetes.

Project description:AimTo evaluate the efficacy and safety of twice-daily insulin degludec/insulin aspart vs. twice-daily biphasic insulin aspart 30 in people with Type 2 diabetes mellitus who were naïve to insulin.MethodsIn this 26-week, multinational, open-label, controlled, two-arm, parallel-group, treat-to-target trial, participants [mean (± sd) age 58.9 (±8.9) years, duration of diabetes 9.5 (±5.9) years, HbA1c 68 (±8.7) mmol/mol or 8.4 (±0.8)% and BMI 31.2 (±4.2) kg/m(2) ) were randomized (1:1) to insulin degludec/insulin aspart (n = 197) or biphasic insulin aspart 30 (n = 197), administered with breakfast and the main evening meal, titrated to a self-monitored plasma glucose target > 3.9 and ≤ 5.0 mmol/l.ResultsThe mean HbA1c was reduced to 49 mmol/mol (6.6%) with insulin degludec/insulin aspart and 48 mmol/mol (6.5%) with biphasic insulin aspart 30. Insulin degludec/insulin aspart achieved the prespecified non-inferiority margin (estimated treatment difference 0.02%; 95% CI -0.12, 0.17). Insulin degludec/insulin aspart was superior in lowering fasting plasma glucose (estimated treatment difference -1.00 mmol/l; 95% CI -1.4, -0.6; P < 0.001) and reducing overall and nocturnal confirmed hypoglycaemia at a similar overall insulin dose compared with biphasic insulin aspart 30. Similar proportions of participants in each arm experienced severe hypoglycaemia. Adverse events were equally distributed.ConclusionsConsistent with previous findings, insulin degludec/insulin aspart twice daily effectively improved long-term glycaemic control, with superior reductions in FPG, and significantly less overall and nocturnal confirmed hypoglycaemia compared with biphasic insulin aspart 30 in people with Type 2 diabetes who were insulin-naïve.

Fasting plasma glucose 6-12 weeks after starting insulin glargine predicts likelihood of treatment success: a pooled analysis.

Project description:To evaluate whether fasting plasma glucose values measured early during insulin therapy can identify patients with Type 2 diabetes who may not achieve adequate glycaemic control after 6 months and will require additional treatment.Patient-level data from seven prospective, randomized, controlled studies using treat-to-target methods were pooled to evaluate the efficacy of insulin glargine. Fasting plasma glucose was measured at baseline, week 6 or 8 (6/8) and week 12. HbA(1c) was measured at week 24 to assess glycaemic control.One thousand and thirty-six patients (56% male, 81% white) were included in the analysis (mean age 56.3 years; duration of diabetes 8.4 years). Baseline mean fasting plasma glucose was 11.2 mmol/l and mean HbA(1c) was 73 mmol/mol (8.8%). After 24 weeks of treatment, mean HbA(1c) decreased to 53 mmol/mol (7.0%); 56% of patients reached a target HbA(1c) ? 53 mmol/mol (7.0%). Significant correlations with week 24 HbA(1c) were obtained for fasting plasma glucose measured at week 6/8 and week 12 (r = 0.32; P < 0.0001 for both). Patients with fasting plasma glucose > 10 mmol/l at week 6/8 or week 12 were significantly less likely to achieve the HbA(1c) target at the end of treatment than patients with fasting plasma glucose < 8.9 mmol/l (P < 0.0001 for both). If fasting plasma glucose was > 10 mmol/l at week 6/8 or week 12, patients had only a 27% chance of reaching the HbA(1c) goal.Fasting plasma glucose remaining > 10 mmol/l after 6-12 weeks of glargine therapy indicates that reaching target HbA(1c) ? 53 mmol/mol (7.0%) is unlikely and calls for individualized attention to consider further therapeutic options.

Low fasting glucose-to-estimated average glucose ratio was associated with superior response to insulin degludec/aspart compared with basal insulin in patients with type 2 diabetes.

Project description:Aims/introductionThe benefits of once-daily insulin degludec/aspart (IDegAsp) compared with basal insulin in type 2 diabetes patients have not been established.Materials and methodsThis was a retrospective observational study. From a basal insulin cohort from three referral hospitals, patients were enrolled who initiated once-daily IDegAsp. A control group maintaining basal insulin was selected by propensity score matching. Glycated hemoglobin (HbA1c) changes over a period of 6 months and associated clinical factors were evaluated.ResultsThe IDegAsp group and the control group comprised of 87 patients, respectively. Baseline HbA1c was comparable between the two groups (8.7 ± 0.9 vs 8.6 ± 0.9%, mean and standard deviation). After 6 months with matched insulin doses, HbA1c in the IDegAsp group was lower than that in the control group (8.1 ± 1.0 vs 8.4 ± 1.1%, P = 0.029). Among baseline variables, fasting plasma glucose (FPG) and fasting C-peptide in the IDegAsp were lower than that in the control (FPG 124.2 ± 38.4 vs 148.0 ± 50.6 mg/dL, P < 0.001). Considering that the lower FPG despite the comparable HbA1c could be related with the efficacy of IDegAsp, subgroup analysis was carried out according to a ratio of FPG-to-estimated average glucose, which is calculated from HbA1c. When compared with each control group, the superiority of IDegAsp in the reduction of HbA1c was significant only in the patients with a lower FPG-to-estimated average glucose ratio (0.49 ± 0.09), but not in those with a higher FPG-to-estimated average glucose ratio (0.79 ± 0.20).ConclusionsWe observed that IDegAsp was more effective than basal insulin in patients with an FPG lower than predicted by HbA1c, which might be related with insulin deficiency and postprandial hyperglycemia in patients on basal insulin therapy.

The importance of the initial period of basal insulin titration in people with diabetes.

Project description:Achieving target glycaemic control is essential in people with diabetes to minimize the risk of long-term complications, and many people with type 2 diabetes will ultimately require basal insulin (BI) therapy to achieve their individualized glycaemic targets. Usually, the first 12?weeks following initiation of BI therapy represents the period when the greatest dose increases and glycaemic reductions occur. Effective glycaemic control combined with minimizing the risk of hypoglycaemia is important to enable the achievement of glycaemic control in the longer term. However, substantial therapeutic inertia exists in clinical practice, both in initiation and up-titration of BI, owing to patient-, physician- and healthcare system-related barriers, including fear of hypoglycaemia and the perception of a burdensome regimen. The more prolonged duration of action, reduced glycaemic variability and lower risk of hypoglycaemia seen with second-generation versus first-generation BI analogues may help alleviate patients' and physicians' concerns and facilitate titration. In turn, optimal BI titration and subsequent metabolic benefits may help improve therapy adherence and self-management. This review details the clinical implications of prompt titration of BI to achieve early glycaemic control, and the importance of minimizing hypoglycaemia risk within the initial titration period. Facilitation of patients' self-management of BI is also addressed.

Basal insulin peglispro versus insulin glargine in insulin-naive type 2 diabetes: IMAGINE 2 randomized trial.

Project description:AimsTo compare, in a double-blind, randomized, multi-national study, 52- or 78-week treatment with basal insulin peglispro or insulin glargine, added to pre-study oral antihyperglycaemic medications, in insulin-naïve adults with type 2 diabetes.Material and methodsThe primary outcome was non-inferiority of peglispro to glargine with regard to glycated haemoglobin (HbA1c) reduction (margin = 0.4%). Six gated secondary objectives with statistical multiplicity adjustments focused on other measures of glycaemic control and safety. Liver fat content was measured using MRI, in a subset of patients.ResultsPeglispro was non-inferior to glargine in HbA1c reduction [least-squares (LS) mean difference: -0.29%, 95% confidence interval (CI) -0.40, -0.19], and had a lower nocturnal hypoglycaemia rate [relative rate 0.74 (95% CI 0.60, 0.91); p = .005), more patients achieving HbA1c <7.0% without nocturnal hypoglycaemia [odds ratio (OR) 2.15 (95% CI 1.60, 2.89); p < .001], greater HbA1c reduction (p < .001), and more patients achieving HbA1c<7.0% [OR 1.97 (95% CI 1.57, 2.47); p < .001]. Total hypoglycaemia rate and fasting serum glucose did not achieve statistical superiority. At 52 weeks, peglispro-treated patients had higher triglyceride (1.9 vs 1.7 mmol/L). alanine transaminase (34 vs 27 IU/L), and aspartate transaminase levels (27 vs 24 IU/L). LS mean liver fat content was unchanged with peglispro at 52 weeks but decreased 3.1% with glargine [difference: 2.6% (0.9, 4.2); p = .002]. More peglispro-treated patients experienced adverse injection site reactions (3.5% vs 0.6%, p < .001).ConclusionsCompared with glargine at 52 weeks, peglispro resulted in a statistically superior reduction in HbA1c, more patients achieving HbA1c targets, less nocturnal hypoglycaemia, no improvement in total hypoglycaemia, higher triglyceride levels, higher aminotransferase levels, and more injection site reactions.

Normal fasting plasma glucose and risk of type 2 diabetes.

Project description:ObjectiveTo investigate the association of normal fasting plasma glucose (FPG) and the risk for type 2 diabetes.Research design and methodsData concerning 13,845 subjects, aged 40-69 years, who had their FPG measured at least three times between 1992 and 2008 were extracted from a database. Three FPG groups were defined (51-82, 83-90, and 91-99 mg/dL). A Cox proportional hazards analysis was applied to estimate the risk of incident diabetes adjusted for other risk factors.ResultsDuring 108,061 person-years of follow-up (8,110 women and 5,735 men), 307 incident cases of type 2 diabetes were found. The final model demonstrated a hazard ratio of 2.03 (95% CI 1.18-3.50) for 91-99 mg/dL and 1.42 (0.42-4.74) for 83-90 mg/dL.ConclusionsOur data suggest that FPG between 91 and 99 mg/dL is a strong independent predictor of type 2 diabetes and should be used to identify people to be further investigated and aided with preventive measures.

Insights into optimal basal insulin titration in type 2 diabetes: Results of a quantitative survey.

Project description:AimsBasal insulin (BI) treatment initiation and dose titration in type 2 diabetes (T2DM) are often delayed. Such "clinical inertia" results in poor glycaemic control and high risk of long-term complications. This survey aimed to determine healthcare professional (HCP) and patient attitudes to BI initiation and titration.MethodsAn online survey (July-August 2015) including HCPs and patients with T2DM in the USA, France and Germany. Patients were ≥18 years old and had been on BI for 6 to 36 months, or discontinued BI within the previous 12 months.ResultsParticipants comprised 386 HCPs and 318 people with T2DM. While >75% of HCPs reported discussing titration at the initiation visit, only 16% to 28% of patients remembered such discussions, many (32%-42%) were unaware of the need to titrate BI, and only 28% to 39% recalled mention of the time needed to reach glycaemic goals. Most HCPs and patients agreed that more effective support tools to assist BI initiation/titration are needed; patients indicated that provision of such tools would increase confidence in self-titration. HCPs identified fear of hypoglycaemia, failure to titrate in the absence of symptoms, and low patient motivation as important titration barriers. In contrast, patients identified weight gain, the perception that titration meant worsening disease, frustration over the time to reach HbA1c goals and fear of hypoglycaemia as major factors.ConclusionA disconnect exists between HCP- and patient-perceived barriers to effective BI titration. To optimize titration, strategies should be targeted to improve HCP-patient communication, and provide support and educational tools.

Comparable efficacy with similarly low risk of hypoglycaemia in patient- vs physician-managed basal insulin initiation and titration in insulin-naive type 2 diabetic subjects: The Italian Titration Approach Study.

Project description:AimsPeople with uncontrolled type 2 diabetes (T2DM) often delay initiating and titrating basal insulin. Patient-managed titration may reduce such deferral. The Italian Titration Approach Study (ITAS) compared the efficacy and safety of insulin glargine 300 U/mL (Gla-300) initiation and titration using patient- (nurse-supported) or physician-management in insulin-naïve patients with uncontrolled T2DM.Materials and methodsITAS was a multicentre, phase IV, 24-week, open-label, randomized (1:1), parallel-group study. Insulin-naïve adults with T2DM for ≥1 year with poor metabolic control initiated Gla-300 after discontinuation of SU/glinides, and were randomized to self-titrate insulin dose (nurse-assisted) or have it done by the physician. The primary endpoint was change in HbA1c . Secondary outcomes included hypoglycaemia incidence and rate, change in fasting self-monitored plasma glucose, patient-reported outcomes (PROs), and adverse events.ResultsThree hundred and fifty five participants were included in the intention-to-treat population. At Week 24, HbA1c reduction from baseline was non-inferior in patient- vs physician-managed arms [least squares mean (LSM) change (SE): -1.60% (0.06) vs -1.49% (0.06), respectively; LSM difference: -0.11% (95% CI: -0.26 to 0.04)]. The incidence and rates of hypoglycaemia were similarly low in both arms: relative risk of confirmed and/or severe nocturnal (00:00-05:59 hours) hypoglycaemia was 0.77 (95% CI: 0.27 to 2.18). No differences were observed for improvement in PROs. No safety concerns were reported.ConclusionsIn the T2DM insulin-naïve, SU/glinides discontinued population, patient-managed (nurse-assisted) titration of Gla-300 may be a suitable option as it provides improved glycaemic control with low risk of hypoglycaemia, similar to physician-managed titration.

Fasting and postprandial plasma glucose contribution to glycated haemoglobin and time in range in people with type 2 diabetes on basal and bolus insulin therapy: Results from a pooled analysis of insulin lispro clinical trials.

Project description:AimsTo investigate the interrelations between glycaemic metrics of fasting plasma glucose (FPG), postprandial glucose (PPG), glycated haemoglobin (HbA1c), and percentage of time in target range 3.9 to 10.0 mmol/L (%TIR) in patients on insulin therapy.Materials and methodsA pooled analysis was conducted using datasets extracted from an integrated database of insulin lispro clinical trials (Eli Lilly and Company). Studies in patients with type 2 diabetes on basal-bolus or basal-plus insulin therapy, and with ≥7-point self-monitored blood glucose profiles were included in the analysis. A multivariate regression model was used to quantify the contribution of FPG and PPG change to the change in HbA1c and %TIR. In addition, a linear regression model was used to describe the relationship between %TIR and HbA1c.ResultsFive studies encompassing 1572 patients met the criteria for inclusion. On average, a 1-mmol/L change in FPG was associated with 2.7 mmol/mol (0.25%) change in HbA1c (range 2.0 to 2.8 mmol/mol [0.18%-0.26%]; all P <0.0001), and a 1-mmol/L change in PPG with 1.8 mmol/mol (0.16%) change in HbA1c (range 1.2 to 2.1 mmol/mol [0.11%-0.19%]; all P <0.01). Furthermore, a 1-mmol/L reduction in FPG and PPG was associated with an increase in TIR of 6.5% (range 5.8%-9.2%) and 5.3% (range 4.1%-8.7%), respectively, all P <0.0001. A decrease in HbA1c of 10.9 mmol/mol (1%) corresponded with an increase in TIR of 8.3%, on average.ConclusionsIn patients with type 2 diabetes on basal-bolus or basal-plus insulin therapy, management of both FPG and PPG is important for achievement of HbA1c and TIR goals.

Modulation of insulin dose titration using a hypoglycaemia-sensitive algorithm: insulin glargine versus neutral protamine Hagedorn insulin in insulin-naive people with type 2 diabetes.

Project description:AimsTo examine whether insulin glargine can lead to better control of glycated haemoglobin (HbA1c) than that achieved by neutral protamine Hagedorn (NPH) insulin, using a protocol designed to limit nocturnal hypoglycaemia.MethodsThe present study, the Least One Oral Antidiabetic Drug Treatment (LANCELOT) Study, was a 36-week, randomized, open-label, parallel-arm study conducted in Europe, Asia, the Middle East and South America. Participants were randomized (1:1) to begin glargine or NPH, on background of metformin with glimepiride. Weekly insulin titration aimed to achieve median prebreakfast and nocturnal plasma glucose levels ≤5.5 mmol/l, while limiting values ≤4.4 mmol/l.ResultsThe efficacy population (n = 701) had a mean age of 57 years, a mean body mass index of 29.8 kg/m², a mean duration of diabetes of 9.2 years and a mean HbA1c level of 8.2% (66 mmol/mol). At treatment end, HbA1c values and the proportion of participants with HbA1c <7.0 % (<53 mmol/mol) were not significantly different for glargine [7.1 % (54 mmol/mol) and 50.3%] versus NPH [7.2 % (55 mmol/mol) and 44.3%]. The rate of symptomatic nocturnal hypoglycaemia, confirmed by plasma glucose ≤3.9 or ≤3.1 mmol/l, was 29 and 48% less with glargine than with NPH insulin. Other outcomes were similar between the groups.ConclusionInsulin glargine was not superior to NPH insulin in improving glycaemic control. The insulin dosing algorithm was not sufficient to equalize nocturnal hypoglycaemia between the two insulins. This study confirms, in a globally heterogeneous population, the reduction achieved in nocturnal hypoglycaemia while attaining good glycaemic control with insulin glargine compared with NPH, even when titrating basal insulin to prevent nocturnal hypoglycaemia rather than treating according to normal fasting glucose levels.
