Abstract
Insulin therapy plays a crucial role in the management of type 2 diabetes as the disease progresses. Over the past century, insulin formulations have undergone significant modifications and bioengineering, resulting in a diverse range of available insulin products. These products show distinct pharmacokinetic and pharmacodynamic profiles. Consequently, various insulin regimens have em-erged for the management of type 2 diabetes, including premixed formulations and combinations of basal and bolus insulins. The utilization of different insulin regimens yields disparate clinical outcomes, adverse events, and, notably, patient-reported outcomes (PROs). PROs provide valuable insights from the patient's perspective, serving as a valuable mine of information for enhancing healthcare and informing clinical decisions. Adherence to insulin therapy, a critical patient-reported outcome, significantly affects clinical outcomes and is influenced by multiple factors. This review provides insights into the clinical effectiveness of various insulin preparations, PROs, and factors impacting insulin therapy adherence, with the aim of enhancing healthcare practices and informing clinical decisions for individuals with type 2 diabetes.

Bai R, Batra K, Yap C, Izuora K. Diabetes-related outcomes with basal-bolus vs. premixed insulin among veterans with type 2 diabetes: A single institutional retrospective study. Am J Med Sci 2023; 366:38-43. [PMID: 37040827 DOI: 10.1016/j.amjms.2023.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 02/24/2023] [Accepted: 04/05/2023] [Indexed: 04/13/2023]
Abstract
BACKGROUND The purpose of this study was to compare diabetes (DM)-related outcomes between basal-bolus (BB) and premixed (PM) insulin regimens. METHODS Retrospective chart review including veterans with type 2 diabetes (T2DM), ≥18 years old with hemoglobin A1c (HbA1c) ≥8%. Outcomes were assessed after one year of BB or PM insulin therapy. Data were analyzed using Chi-square/Fisher exact tests and logistic regression. RESULTS Out of 140 enrolled subjects (70 BB and 70 PM), 94% were males with average age and duration of DM of 65.7 ± 10.1 and 12.9 ± 9 years, respectively. The BB and PM groups were similar in age, gender distribution, HbA1c, body mass index (BMI) and DM duration at baseline. Following 1 year of treatment, there was no significant difference between the groups for change in HbA1c (-1.9 ± 1.8 vs -2.1 ± 1.9%, p = 0.3) or hypoglycemia rate (30% vs 21.4%, p = 0.3), respectively. There was similar increase in average BMI in both groups (0.84 ± 3.1 for BB vs 0.4 ± 2.2 kg/m2 for PM, p = 0.2). CONCLUSIONS There were no significant differences for glycemic control, hypoglycemia rate or BMI between the BB or PM insulin groups. These results suggest PM insulin is equally effective and safe as BB insulin.

Abstract
INTRODUCTION This systematic review aims to present the current evidence base with respect to the initiation and intensification of insulin therapy with glargine 100 U/mL (Gla-100) compared to other insulins in people with type 2 diabetes mellitus (T2DM). METHODS A systematic literature search of PubMed (MEDLINE), EMBASE, and the Cochrane Central Register of controlled clinical trials databases was performed to identify studies published up to September 30, 2020 that compared the effects of Gla-100 to that of other insulin regimens in people with T2DM. Relevant information pertaining to the predefined outcomes of interest was extracted. Glycated hemoglobin (HbA1c) change and response rates along with overall hypoglycemia incidence were the primary efficacy and safety outcomes of interest. RESULTS Seventy-nine studies (63 interventional and 16 non-interventional) in which Gla-100 was either initiated in previously insulin-naïve patients (n = 57) or used in an intensified regimen (n = 22) were identified and evaluated. In insulin-naïve patients, most studies demonstrated that Gla-100 was significantly better compared with premixed insulins and similar compared with neutral protamine Hagedorn (NPH) insulin, second-generation basal insulins, co-formulations, and other first-generation basal insulins in terms of the primary efficacy parameters. Overall hypoglycemia risk with Gla-100 was significantly lower compared with NPH, premixed, coformulation, and other first-generation basal insulins and significantly higher compared with second-generation basal insulins. In studies with intensified regimens, efficacy outcomes with Gla-100 were significantly better compared with insulin detemir (IDet); similar compared with NPH, second-generation basal insulins, co-formulations; and with premixed insulins. In these studies, overall hypoglycemia risk with Gla-100 was significantly lower compared with IDet and comparable to NPH, premixed insulins, co-formulations, and second-generation basal insulins. In addition, most intensification studies also revealed a significantly lower risk of nocturnal hypoglycemia with Gla-100-based regimens versus NPH and premixed insulins and a significantly greater risk compared to second-generation basal insulins. CONCLUSIONS The evidence presented in this review suggests that Gla-100 is an effective option for both insulin initiation and intensification strategies used in the management of T2DM.

In Vitro and In Vivo Profiles and Characterization of Insulin Nanocarriers Based in Flexible Liposomes Designed for Oral Administration. LETT DRUG DES DISCOV 2019.

Abstract
Background:
Alternatives routes of delivery for Insulin have been evaluated to improve
treatment for Diabetes Mellitus. The oral route is the most convenient physiologically; it releases in a
similar way to endogenous secretion. Flexible liposomes have deformable abilities to pass through
membranes with adequate therapeutic effects, but they have been tested only dermally.
Objective:
Our aim was to develop an oral nanocarrier based on flexible liposomes for insulin with
polymer addition to reduce gastrointestinal degradation.
Methods:
Different percentages of polyethylene glycol were added to a conventional formulation of
flexible liposomes. The manufacturing procedure was the heating method. Z potential, size particle,
polydispersity index and encapsulation percentage were evaluated. A release profile was performed
in the stomach and intestinal pH mediums by two-stage reverse dialysis method. The in-vivo test was
performed in experimental diabetic rats by oral, transdermal and subcutaneous routes.
Results:
All the formulations showed polydispersity but adequate Z potential. The 10% PEG
formulation obtained the best insulin enclosure with 81.9%. The insulin integrity after preparation
was confirmed by polyacrylamide gel electrophoresis. PEG and non-PEG formulations showed
similar behavior in acid release profile but the release and stability of lipid structures were better and
longer in intestinal pH conditions. In vivo tests showed a reduction to normal glucose levels only in
subcutaneous route.
Conclusion:
The polymer inclusion in flexible liposomes generates an adequate nanocarrier for
proteins in terms of stability and composition; although its in-vivo use reduces glucose levels in
subcutaneous route, the effect was not adequate in oral route.

Abstract
INTRODUCTION This study compared basal analog (BA: glargine U100/mL and detemir) and premix (PM: human, lispro and aspart biphasic) insulin regimens in terms of their efficacy and safety in type 2 diabetes mellitus patients. METHODS Searches of MEDLINE, Embase, and CENTRAL identified primary randomized controlled trials (RCTs) ≥ 12 weeks in duration that compared BA or PM insulin regimens in adults with T2DM, with ≥ 30 patients per arm. A systematic literature review and a pairwise meta-analysis were performed using a random effects model adjusted for between-study variability. Analyses were conducted based on frequency of bolus insulin and PM injections, PM ratio and type, BA type, race, follow-up period, and baseline glycosylated hemoglobin (HbA1c). RESULTS Twenty-two primary RCTs with 9691 patients were included. The BA and PM regimens yielded similar changes in HbA1c and postprandial glucose levels, with a statistically significant reduction in fasting glucose [mean difference (MD) - 0.61 mmol/L (95% confidence interval (CI) - 0.90, - 0.32), I2 = 89.6%]. The BA regimens showed significantly reduced rates of total hypoglycemia [odds ratio (OR) 0.77 (95% CI 0.64, 0.92), I2 = 65.3%] and changes in body weight [MD - 0.48 kg (95% CI - 0.86, - 0.11), I2 = 75.7%] compared to PM regimens. Stratification by PM type and dosing ratio demonstrated statistically significant reductions in HbA1c favoring BA compared to human [MD - 0.39% (95% CI - 0.60, - 0.18), I2 = 61.8%] or 50/50-ratio [MD - 0.22% (95% CI - 0.40, - 0.04), I2 = 0.0%] PM regimens. Other subgroup analyses found no difference in HbA1c change between the BA and PM regimens. CONCLUSION When compared to PM regimens, BA regimens yielded similar efficacies and better safety profiles in patients with type 2 diabetes mellitus. FUNDING Sanofi (Shanghai, China).

Abstract
OBJECTIVE Insulin is one of the most efficacious treatments for hyperglycemia; however, adherence to insulin therapy is poor, impacting its efficacy. Thus, the objectives of this study were to determine if persistent use of a new insulin delivery option, V-Go, improved clinical outcomes and secondly compare clinical and economic outcomes between persistent use of V-Go and conventional insulin delivery (CID). METHODS A retrospective review of an outpatient clinic's records was performed. Patients initiating V-Go with documented persistent use of V-Go or resumed persistent use of CID after short-term V-Go use were included (≥5 months of persistency). Baseline data and a total of two post-V-Go or CID initiation visits were examined for clinical and economic outcomes. Cost-effectiveness of each therapy was calculated by dividing the mean cost difference (baseline to office visit 2) by the mean change in A1c (baseline to office visit 2). RESULTS V-Go persistent patients had a significant decrease in A1c (-1.42; p < 0.001). Between baseline and office visit two, they required less insulin units/day and units/kg and had significantly lower A1c, insulin units/day, insulin units/kg, and 30-day insulin costs than CID patients. V-Go persistent patients had a lower incremental cost by $695.61 per 1% change in A1c compared to CID persistent patients. CONCLUSIONS Utilization of a new insulin delivery option resulted in improved clinical outcomes compared to CID and was more cost-effective. Clinicians and health plans should consider the use of new insulin delivery options for the management of patients with diabetes on insulin therapy to promote persistence.

Abstract
A large number of patients with type 2 diabetes (T2D) on basal insulin do not reach their HbA1c goals and require additional therapy to address postprandial hyperglycemia. Guidelines from expert bodies have outlined several approaches to accomplish postprandial glucose (PPG) control, and recent literature suggests several more. This article provides strategies for primary care physicians caring for patients with T2D who do not achieve glycemic control with basal insulin alone. Current treatment guidelines and strategies for improving PPG control are reviewed, including the efficacy, safety, and cost-effectiveness of rapid-acting insulin (RAI) analogs, premixed insulin, glucagon-like peptide-1 (GLP-1) receptor agonists (RAs), dipeptidyl peptidase 4 inhibitors, sodium-glucose cotransporter 2 inhibitors, and α-glucosidase inhibitors. Other approaches, such as combinations of newer basal insulin plus RAI and a fixed-ratio combination of basal insulin and a GLP-1 RA, are also described.

Abstract
AIM To evaluate the concordance between data derived from randomized controlled trial (RCT) and real-world estimates of HbA1c and weight change after 24 weeks of initiation of a basal-bolus compared with a premixed insulin regimen in people with Type 2 diabetes. METHODS Data eight RCTs were pooled after a systematic review of studies examining basal-bolus (n = 1893) or premixed (n = 1517) regimens. Real-world data were extracted from the UK primary care dataset for people on basal-bolus (n = 7483) or premixed insulin regimens (n=10 744). The mean differences between HbA1c and weight from baseline were calculated using t-tests, while analysis of variance was used to compare the two treatment regimens. Linear regression analyses were used to determine the predictors of this change. RESULTS Both insulin regimens were associated with HbA1c reductions (real-world data -0.28%; RCT data, -1.4%) and weight gain (real-world data, +0.27 kg; RCT data, +2.96 kg) but there were no significant differences between basal-bolus and premixed insulin. Discordances in the pattern of treatment response were observed, however, between real-world and RCT data for both insulin regimens. For any given baseline HbA1c concentration, the change in HbA1c in the RCTs was greater than in real-world conditions and for those with baseline weight above ~60 kg, RCT data showed overall weight gain in contrast to slight weight loss in the real-world population. Lastly, for both randomized controlled trial and real-world populations, while greater baseline weight was associated with reduced response to treatment, the association was much steeper in the RCT than in the real-world population. In addition, greater baseline weight was associated with greater weight reductions in both premixed insulin and basal-bolus insulin regimens, although to a lesser extent with the latter. CONCLUSION These results highlight specific discrepancies in the HbA1c reduction and weight change in insulin regimen between real world versus RCT populations; with greater reduction in HbA1c and greater increase in weight observed in the RCT population than in the real-world population. Also, the basal-bolus regimens in both real-world and RCT populations showed greater reduction in HbA1c compared to the premix regimen (though more marked in RCTs), while the premix regimen showed greater increase in weight in real-world, as against basal-bolus in the RCT population.

Abstract
AIM As type 2 diabetes mellitus progresses, most patients require treatment with basal insulin in combination with another agent to achieve recommended glycaemic targets. The purpose of this systematic review was to examine the evidence supporting the use of the available add-on treatments [rapid-acting insulin (RAI), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), dipeptidyl peptidase (DPP)-4 inhibitors and sodium-glucose cotransporter-2 (SGLT-2) inhibitors] to basal insulin. METHODS MEDLINE, EMBASE and EBSCOhost were searched for English-language articles, and all those captured were original articles (case studies and narrative reviews were omitted). Data on study design, population demographics, interventions and outcomes were tabulated. The extracted outcome data included changes in glycated haemoglobin (HbA1c), fasting plasma glucose (FPG) and postprandial plasma glucose (PPG), as well as body weight and safety data. RESULTS A total of 88 publications were deemed relevant. All treatments reduced HbA1c and FPG. The most pronounced reductions in PPG, an unmet need in patients not controlled by basal insulin, were seen following administration of RAIs and short-acting GLP-1 RAs, although data for this outcome are generally lacking. Body weight benefits were observed with GLP-1 RAs and SGLT-2 inhibitors. However, as only articles in English were included, the result was a possible publication bias, while the diversity of study designs and drug combinations limited comparisons between studies. CONCLUSION The evidence supports effectiveness of the available add-on treatments to basal insulin. However, other factors, such as potential body-weight increases, convenience/compliance and adverse events, particularly hypoglycaemia, should be considered on a patient-by-patient basis to optimalize treatment outcomes.

Abstract
OBJECTIVE This study aims to compare the effectiveness of insulin glargine 300 U/mL (Gla-300) with its accompanying patient support program with that of other basal insulin and available patient support programs in patients with type 2 diabetes (T2D) in a real-world setting in terms of achieving HEDIS (Healthcare Effectiveness Data and Information Set) individualized glycemic targets without documented symptomatic hypoglycemia. METHODS Achieve Control is a US-based, multicenter, randomized, open-label, active-controlled, parallel group pragmatic Phase IV trial in insulin-naïve patients with T2D uncontrolled on ≥2 oral antidiabetes drugs (OAD) and/or glucagon-like peptide-1 receptor antagonists (GLP-1 RA). Inclusion criteria include a diagnosis of T2D, age ≥18 years, and glycated hemoglobin (HbA1c) between 8.0% and 11.0%. Patients will be assigned to either the Gla-300 or other basal insulin group. The primary end point is the proportion of patients achieving HEDIS HbA1c targets (<8.0% [64 mmol/mol] in patients with comorbidities or aged ≥65 years; <7.0% [58 mmol/mol] in all other patients) without occurrence of symptomatic hypoglycemia (blood glucose ≤70 mg/dL) from baseline to 6 months. Secondary end points include rates of documented symptomatic nocturnal hypoglycemia and severe hypoglycemia; change from baseline in HbA1c, fasting glucose, and body weight; treatment persistence; patient-reported outcomes; and healthcare resource utilization. Planned enrollment is 3270 patients across approximately 400 clinical sites. CONCLUSION Pragmatic clinical trials offer the potential to assess comparative effectiveness in broadly based patient populations receiving care (with or without a corresponding educational support program) in real-world clinical settings. The results of Achieve Control should elucidate the benefits of management of T2D with Gla-300 versus other basal insulins in terms of patient outcomes, experiences, and perceptions, and its impact on healthcare resource utilization and cost. CLINICAL TRIAL REGISTRATION www.clinicaltrials.gov identifier is NCT02451137.

Abstract
Many patients with type 2 diabetes mellitus (T2DM) require insulin therapy. If basal insulin fails to achieve glycemic control, insulin intensification is one possible treatment intensification strategy. We summarized clinical data from randomized clinical trials designed to compare the efficacy and safety of basal-bolus and premixed insulin intensification regimens. We defined a between-group difference of ≥0.3% in end-of-study glycated hemoglobin (HbA1c) as clinically meaningful. A PubMed database search supplemented by author-identified papers yielded 15 trials which met selection criteria: randomized design, patients with T2DM receiving basal-bolus (bolus injection ≤3 times/day) vs. premixed (≤3 injections/day) insulin regimens, primary/major endpoint(s) HbA1c- and/or hypoglycemia-related, and trial duration ≥12 weeks. Glycemic control improved with both basal-bolus and premixed insulin regimens with - in most cases - acceptable levels of weight gain and hypoglycemia. A clinically meaningful difference between regimens in glycemic control was recorded in only four comparisons, all of which favored basal-bolus therapy. The incidence of hypoglycemia was significantly different between regimens in only three comparisons, one of which favored premixed insulin and two basal-bolus therapy. Of the four trials that reported a significant difference between regimens in bodyweight change, two favored basal-bolus therapy and two favored premixed insulin. Thus, on a population level, neither basal-bolus therapy nor premixed insulin showed a consistent advantage in terms of glycemic control, hypoglycemic risk, or bodyweight gain. It is therefore recommended that clinicians should adopt an individualized approach to insulin intensification - taking into account the benefits and risks of each treatment approach and the attitude and preferences of each patient - in the knowledge that both basal-bolus and premixed regimens may be successful.

Abstract
The purpose of this study was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the effect of intensified insulin regimens (basal-bolus versus premixed) on glycemic control in patients with type 2 diabetes. We conducted an electronic search until March 2015 on many electronic databases including online registries of ongoing trials. All RCTs comparing basal-bolus with premixed insulin regimens, with a duration of >12 weeks and with >30 patients per arm, were included. Investigators extracted data on study characteristics, outcome measures, and methodological quality. We found thirteen RCTs lasting 16-60 weeks and involving 5255 patients assessed for the primary endpoint (reduction of HbA1c from baseline). Meta-analysis of change in HbA1c level between basal-bolus and premixed insulin regimens resulted in a small and non-significant difference of 0.09% (95% CI -0.03 to 0.21), with substantial heterogeneity between studies (I(2) = 74.4%). There was no statistically significant difference in the event rate for overall hypoglycemia (0.16 episode/patient/year, 95%CI -2.07 to 2.3), weight change (-0.21 kg, -0.164 to 0.185), and daily insulin dose (-0.54 U/day, -2.7 to 1.6). The likelihood for reaching the HbA1c <7% was 8% higher (3-13%, I(2) = 68.8%) with the basal-bolus as compared with the premixed regimen. There is no clinically relevant difference in the efficacy of basal-bolus versus premixed insulin regimens for HbA1c decrease in type 2 diabetic patients. These findings may be helpful to adapt treatment to individual patient needs.

Abstract
AIM We aim to evaluate the effects of biphasic insulin compared with a basal bolus insulin regimen on glycaemic control, total daily insulin requirements, risk of hypoglycaemia, weight and quality of life in patients with diabetes mellitus. METHODS MEDLINE, EMBASE, PubMed and Scopus databases were searched for studies up to November 2013. Interventions that lasted for more than four weeks and were reported in English were considered for the review. Meta-analysis was performed on eligible studies. RESULTS Fifteen randomized controlled trial studies, involving 4384 patients, were included. Greater HbA1c reductions were seen with basal-bolus compared with biphasic insulin regimens, between-treatment weighted mean difference (WMD) for baseline-to-endpoint changes in HbA1c was -0.2% (95% CI: -0.36 to -0.03) [-2.2 (-3.9, -0.3) mmol/mol]. In non-insulin naïve (n = 8) patients with Type 2 diabetes, HbA1c reduction was greater in the basal bolus group; WMD = -0.22% (95% CI: -0.42 to -0.02) [-2.4 (-4.6, -0.2) mmol/mol], but in insulin naïve patients (n = 5), HbA1c was equivalent between the two regimens; WMD (-0.15% (95% CI: -0.52 to 0.22) [-1.6 (-5.7, 2.4) mmol/mol]. Total daily insulin requirements and weight were increased with both regimens, whereas hypoglycaemia rates were comparable between the two regimens. Greater HbA1c reduction was observed in the basal bolus group compared with the biphasic regimen at the expense of higher daily insulin requirements and weight gain, but with no greater risk of hypoglycaemia. CONCLUSIONS Biphasic and basal bolus regimens were equally effective in reducing HbA1c in insulin naïve patients with Type 2 diabetes and both regimens are equally effective for initiating insulin in Type 2 diabetes.

Abstract
Rising healthcare costs and the management of diabetes are financially straining to healthcare organizations. The study purpose was to examine whether a direct relationship existed between the cost of hospitalization, length of stay, excess admission days, and discharge blood glucose (DC-BG) levels and utilizing a standardized glycemic protocol. A retrospective cohort analysis was conducted of adult diabetes mellitus type 2 (DM-2) patients' pre-diabetic protocol (January 1, 2011-December 31, 2011) and post-diabetic protocol (August 1, 2012-October 31, 2012). The sample included DM-2 inpatients aged ≥ 18 years admitted without complications and/or with abnormal fasting blood glucose. Pre-protocol sample comprised n = 346 subjects and post-protocol sample comprised n = 149 subjects. Patients who received the diabetic protocol in 2012 experienced a decrease in the DC-BG (p < .05) and decrease in excess admission days (p < .05). Evidence supports that utilizing a standardized glycemic protocol improves glycemic control and reduces healthcare cost.
