Comparative physicochemical and structural characterisation studies establish high biosimilarity between BGL-ASP and reference insulin aspart.

Biosimilar insulin analogues are increasing market access for diabetic patients globally. Scientific establishment of biosimilarity is cornerstone of this key change in the medical landscape. BGL-ASP is a biosimilar insulin aspart developed by BioGenomics Limited, India. BioGenomics has considered a stepwise approach in generating the totality of evidence required to establish similarity with reference product. Insulin aspart is a recombinant rapid-acting human insulin analogue utilised in the treatment of type-1 and type-2 diabetes mellitus. The single amino acid substitution at position B28 where proline is replaced with aspartic acid results in a decreased propensity to form hexamers, thus increasing the absorption rate on subcutaneous administration compared to native insulin. In order to establish the safety and efficacy of BGL-ASP, the critical quality attributes (CQAs) of BGL-ASP are identified based on the impact created on biological activity, pharmacokinetic/pharmacodynamic (PK/PD), immunogenicity and safety. The CQAs of insulin aspart are related to product structure, purity and functionality and are characterised using a series of state-of-the-art orthogonal analytical tools. The primary protein sequence, the secondary, tertiary and quaternary structure are found to be highly similar for BGL-ASP and reference product. The product related impurities of insulin aspart and the assay content are determined using high performance liquid chromatography (HPLC) based analysis and is similar for BGL-ASP and reference insulin aspart sourced from United States of America (US), Europe Union (EU) and India. The safety, efficacy and immunogenicity of BGL-ASP is also found to be comparable with reference product and is confirmed through the clinical trials conducted as recommended by International Council for Harmonisation of Technical Requirements of Pharmaceuticals for Human Use (ICH) and European Medicines Agency (EMA) guidelines. The data encompassed in this study demonstrates that reference insulin aspart and BGL-ASP are highly similar in terms of structural, physicochemical, and biological properties, thus confirming its safety and efficacy for usage as potential alternative economical medicinal treatment for diabetes mellitus.

Study protocol for a randomised open-label clinical trial examining the safety and efficacy of the Android Artificial Pancreas System (AAPS) with advanced bolus-free features in adults with type 1 diabetes: the 'CLOSE IT' (Closed Loop Open SourcE In Type 1 diabetes) trial.

INTRODUCTION: Multiple automated insulin delivery (AID) systems have become commercially available following randomised controlled trials demonstrating benefits in people with type 1 diabetes (T1D). However, their real-world utility may be undermined by user-associated burdens, including the need to carbohydrate count and deliver manual insulin boluses. There is an important need for a 'fully automated closed loop' (FCL) AID system, without manual mealtime boluses. The (Closed Loop Open SourcE In Type 1 diabetes) trial is a randomised trial comparing an FCL AID system to the same system used as a hybrid closed loop (HCL) in people with T1D, in an outpatient setting over an extended time frame. METHODS AND ANALYSIS: Randomised, open-label, parallel, non-inferiority trial comparing the Android Artificial Pancreas System (AAPS) AID algorithm used as FCL to the same algorithm used as HCL. Seventy-five participants aged 18-70 will be randomised (1:1) to one of two treatment arms for 12 weeks: (a) FCL-participants will be advised not to bolus for meals and (b) HCL-participants will use the AAPS AID algorithm as HCL with announced meals. The primary outcome is the percentage of time in target sensor glucose range (3.9-10.0 mmol/L). Secondary outcomes include other glycaemic metrics, safety, psychosocial factors, platform performance and user dietary factors. Twenty FCL arm participants will participate in a 4-week extension phase comparing glycaemic and dietary outcomes using NovoRapid (insulin aspart) to Fiasp (insulin aspart and niacinamide). ETHICS AND DISSEMINATION: Approvals are by the Alfred Health Ethics Committee (615/22) (Australia) and Health and Disability Ethics Committees (2022 FULL 13832) (New Zealand). Each participant will provide written informed consent. Data protection and confidentiality will be ensured. Study results will be disseminated by publications, conferences and patient advocacy groups. TRIAL REGISTRATION NUMBERS: ACTRN12622001400752 and ACTRN12622001401741.

Real-world study of the concomitant use of biphasic insulin aspart 30/70 with GLP-1 receptor agonist versus first-generation basal insulin with GLP-1 receptor agonist in type 2 diabetes.

AIMS: Combining insulin with a glucagon-like peptide-1 receptor agonist (GLP-1RA) to treat type 2 diabetes (T2D) is common. While many studies have investigated concomitant therapy with basal insulin+GLP-1RA, few have reported on premixed insulin+GLP-1RA. We aimed to address this gap using data from the Clinical Practice Research Datalink Aurum database in England. METHODS: This retrospective cohort study with propensity score matching assessed glycaemic levels and other clinical outcomes in people with T2D, comparing biphasic insulin aspart 30/70 (BIAsp 30) + GLP-1RA with basal insulin (insulin detemir/glargine U100) + GLP-1RA (from 2006 to 2021). RESULTS: In total, 4770 eligible people were identified; 1511 had a BIAsp 30 + GLP-1RA regimen and were propensity score-matched to an equal number receiving basal+GLP-1RA. There was no significant difference in glycated haemoglobin (HbA1c) reduction between cohorts at 6 months (p = 0.15), with a decrease of -1.07 (95% CI: -1.16; -0.98) %-points (-11.7 mmol/mol [95% CI: -12.7; -10.7]) in the BIAsp 30 + GLP-1RA cohort, versus -0.97 (95% CI: -1.07; -0.88) %-points (-10.6 mmol/mol [95% CI: -11.7; -9.6]) in the basal+GLP-1RA cohort. Body mass index (BMI) decreased by -0.35 kg/m2 (95% CI: -0.52;-0.18) at 6 months with BIAsp 30 + GLP-1RA, versus -0.72 kg/m2 (95% CI: -0.90;-0.54) with basal+GLP-1RA (p = 0.003). BMI was influenced by the initiation sequence of GLP-1RA in relation to insulin (p < 0.0001). Hypoglycaemia rates were low and not significantly different between cohorts. CONCLUSIONS: Combining BIAsp 30 + GLP-1RA provides glycaemic control with no significant difference to that of propensity score-matched people receiving basal insulin+GLP-1RA, with no increase in hypoglycaemia risk or weight gain.

Faster-acting insulin aspart versus insulin aspart in the treatment of type 1 or type 2 diabetes during pregnancy and post-delivery (CopenFast): an open-label, single-centre, randomised controlled trial.

BACKGROUND: Faster-acting insulin aspart (faster aspart) is considered safe for use during pregnancy and breastfeeding but has not been evaluated in this population. We aimed to evaluate the effect of faster aspart versus insulin aspart on fetal growth, in women with type 1 or type 2 diabetes during pregnancy and post-delivery. METHODS: This open-label, single-centre, superiority trial was conducted at Rigshospitalet, Copenhagen, Denmark. Participants aged 18 years or older with type 1 or type 2 diabetes were stratified by diabetes type and insulin treatment modality (multiple daily injections or insulin pump), randomly assigned 1:1 to faster aspart or insulin aspart, from 8 weeks and 0 days (8+0) of gestation to 13+6 weeks of gestation, and followed up until 3 months post-delivery. Primary outcome was infant birthweight SD score. Secondary outcomes included HbA1c as well as maternal and fetal outcomes in all participants during the trial. This trial is registered with ClinicalTrials.gov, NCT03770767. FINDINGS: Between Nov 11, 2019 and May 10, 2022, 109 participants were included in the faster aspart group and 107 in the insulin aspart group. Primary outcome data were available in 203 (94%) of 216 participants, and no participants discontinued treatment during the trial. Mean birthweight SD score was 1·0 (SD 1·4) in the faster aspart group versus 1·2 (1·3) in the insulin aspart group; estimated treatment difference -0·22 [-0·58 to 0·14]; p=0·23. At 33 weeks of gestation, mean HbA1c was 42 mmol/mol (SD 6 mmol/mol; 6·0% [SD 0·9%]) versus 43 mmol/mol (SD 7 mmol/mol; 6·1% [SD 1·2%]); estimated treatment difference -1·01 (-2·86 to 0·83), p=0·28. No additional safety issues were observed with faster aspart compared with insulin aspart. INTERPRETATION: Treatment with faster aspart resulted in similar fetal growth and HbA1c, relative to insulin aspart, in women with type 1 or type 2 diabetes. Faster aspart can be used in women with type 1 or type 2 diabetes during pregnancy and post-delivery with no additional safety issues. FUNDING: Novo Nordisk.

Functional insulin aspart/insulin degludec-based microneedles for promoting postprandial glycemic control.

Insulin aspart (IAsp) and insulin degludec (IDeg), as the third generation of insulin, have a faster onset time or a more durable action period, which may simulate the secretion of insulin under physiological conditions. Microneedles (MNs) are transdermal delivery devices that may allow diabetic patients to easily deploy transdermal insulin therapy while considerably reducing injection pain. In this study, we investigated the combination of dissolving MNs with IAsp or IDeg therapy as an alternative to daily multiple insulin injections, aiming to improve glycemic control and patient compliance. Mechanical properties of the MNs, structural stability of insulin encapsulated in the MNs, and transdermal application characteristics were studied to assess the practicality of insulin-loaded MNs for diabetes therapy. In vivo experiments conducted on diabetic rats demonstrated that the IAsp- and IDeg-loaded MNs have comparable blood glucose control abilities to that of subcutaneous injections. In addition, the therapeutic properties of insulin-loaded MNs under diverse dietary conditions and application strategies were further investigated to provide new information to support future clinical trials. Taken together, the proposed MNs have the potential to improve balances between glycemic control, hypoglycemia risk, and convenience, providing patients with simpler regimens. STATEMENT OF SIGNIFICANCE: 1. The fabricated functional insulin-loaded dissolving microneedles closely matched the glucose rise that occurs in response to meals, demonstrating promising alternatives for multiple daily insulin injections. 2. The hypoglycemic properties of insulin microneedles were investigated under diverse dietary conditions and application strategies, yielding new information to support future clinical trials. 3. Molecular dynamics simulations were utilized to study the interactions between the insulin and microneedle matrix materials, providing a strategy for theoretically understanding drug stability as well as the release mechanism of drug-loaded microneedles.

Evaluation of blood glucose changes with regular versus rapid-acting insulin for hyperglycaemia management in the emergency department.

OBJECTIVES: As emergency department (ED) visits secondary to hyperglycaemia increase, goals should focus on optimising treatment to minimise the length of stay (LOS). Both regular and rapid-acting insulins can effectively treat hyperglycaemia, but have different pharmacokinetic profiles. The purpose of this study is to compare blood glucose (BG) reduction over time in patients receiving subcutaneous regular versus rapid-acting insulin in the ED. METHODS: This retrospective chart review from 1 January 2018 to 31 December 2020 included adult ED patients with a BG ≥200 mg/dl who received subcutaneous regular insulin or insulin aspart. The primary endpoint was a change in BG immediately before and ≥30 min after insulin administration over time. RESULTS: There were 279 patients included in the study (108 regular insulin and 171 insulin aspart). Change in BG over time was 41.5 mg/dl/h in the regular insulin group and 47 mg/dl/h in the insulin aspart group (P = 0.36). There was no difference in hypoglycaemic events, ED LOS, time from insulin administration to discharge and total change in BG during ED stay. Patients who received regular insulin required less additional insulin doses (8.3% vs. 18.1%, P = 0.02), received a greater volume of intravenous fluids (1629 ml vs. 1280 ml, P = 0.02) and higher weight-based dose for the first insulin dose (0.11 units/kg vs. 0.10 units/kg, P = 0.02). CONCLUSION: There was no significant difference in BG reduction between insulin types for hyperglycaemic patients treated in the ED. This suggests that regular insulin and rapid-acting insulin have similar efficacy in the treatment of hyperglycaemia in the ED.

Insulin Tregopil: An Ultra-Fast Oral Recombinant Human Insulin Analog: Preclinical and Clinical Development in Diabetes Mellitus.

Insulin therapy is indispensable for achieving glycemic control in all patients with type 1 diabetes mellitus and many patients with type 2 diabetes mellitus. Insulin injections are associated with negative connotations in patients owing to administration discomfort and adverse effects such as hypoglycemia and weight gain. Insulin administered orally can overcome these limitations by providing a convenient and effective mode of delivery with a potentially lower risk of hypoglycemia. Oral insulin mimics the physiologic process of insulin secretion, absorption into the portal circulation, and subsequent peripheral delivery, unlike the subcutaneous route that results in peripheral hyperinsulinemia. Insulin tregopil (IN-105), a new generation human recombinant insulin, methoxy (polyethylene glycol) hexanoyl human recombinant insulin, is developed by Biocon as an ultra-fast onset short-acting oral insulin analog. This recombinant oral insulin is a single short-chain amphiphilic oligomer modified with the covalent attachment of methoxy-triethylene-glycol-propionyl moiety at Lys-ß29-amino group of the B-chain via an amide linkage. Sodium caprate, an excipient in the insulin tregopil formulation, is a permeation enhancer that increases its absorption through the gastrointestinal tract. Also, meal composition has been shown to non-significantly affect its absorption. Several global randomized, controlled clinical trials have been conducted in type 1 and type 2 diabetes patients towards the clinical development of insulin tregopil. The formulation shows post-prandial glucose control that is more effective than placebo throughout the meal period; however, compared with an active comparator insulin aspart, the post-prandial control is more effective mainly in the early post-meal period. It shows a good safety profile with a lower incidence of clinically significant hypoglycemia. This review covers the overall clinical development of insulin tregopil establishing it as an ultra-fast onset, short-acting oral insulin analog for optimizing post-prandial glucose.

A Comparison of Faster Insulin Aspart with Standard Insulin Aspart Using Hybrid Automated Insulin Delivery System in Active Children and Adolescents with Type 1 Diabetes: A Randomized Double-Blind Crossover Trial.

Objective: To evaluate the use of faster acting (FIA) and standard insulin aspart (SIA) with hybrid automated insulin delivery (AID) in active youth with type 1 diabetes. Research Design and Methods: In this double-blind multinational randomized crossover trial, 30 children and adolescents with type 1 diabetes (16 females; aged 15.0 ± 1.7 years; baseline HbA1c 7.5% ± 0.9% [58 ± 9.8 mmol/mol]) underwent two unrestricted 4-week periods using hybrid AID with either FIA or SIA in random order. During both interventions, participants were using the hybrid AID (investigational version of MiniMed™ 780G; Medtronic). Participants were encouraged to exercise as frequently as possible, capturing physical activity with an activity monitor. The primary outcome was the percentage of sensor glucose time above range (180 mg/dL [10.0 mmol/L]) measured by continuous glucose monitoring. Results: In an intention-to-treat analysis, mean time above range was 31% ± 15% at baseline, 19% ± 6% during FIA use, and 20% ± 6% during SIA use with no difference between treatments: mean difference = -0.9%; 95% CI: -2.4% to 0.6%; P = 0.23. Similarly, there was no difference in mean time in range (TIR) (78% and 77%) or median time below range (2.5% and 2.8%). Glycemic outcomes during exercise or postprandial periods were comparable for the two treatment arms. No severe hypoglycemia or diabetic ketoacidosis events occurred. Conclusions: FIA was not superior to SIA with hybrid AID system use in physically active children and adolescents with type 1 diabetes. Nonetheless, both insulin formulations enabled high overall TIR and low time above and below ranges, even during and after documented exercise. Trial Registration Clinicaltrials.gov: NCT04853030.

Efficacy of switching from basal-bolus insulin therapy to twice-daily insulin degludec/insulin aspart co-formulation plus insulin aspart in patients with poorly controlled type 2 diabetes.

OBJECTIVE: The aim of this study was to evaluate the efficacy of twice-daily (BID) insulin degludec/insulin aspart (IDegAsp) co-formulation + once-daily (OD) bolus insulin aspart (IAsp) injection (IDegAsp BID-Plus) as simplified intensive insulin therapy in patients with poorly controlled type 2 diabetes mellitus (T2DM) with basal-bolus insulin therapy (BBIT). PATIENTS AND METHODS: The retrospective study included 155 patients who switched from BBIT to IDegAsp BID-Plus. After the initiation of the treatment, 73 patients continued regular follow-up and insulin doses, number of injections, hemoglobin A1c (HbA1c) levels, and other parameters were recorded from their files at baseline, 24, and 52 weeks. RESULTS: The mean age of the study population was 54.3±10.2 years, the duration of T2DM was 9.7±5.7 years, fasting plasma glucose (FPG) was 252.7±66.7 mg/dl, and HbA1c levels were 10.5±1.5%. Among the included patients, 15 patients received five injections, 51 patients received four injections, and 7 patients received three injections per day. There was a significant decrease in HbA1c (respectively; 10.46±1.54%, 7.97±1.24%, 7.98±1.23%, baseline and 6th-month p<0.001, baseline and 12th-month p<0.001), FPG (respectively; 251.6±66.5 mg/dl, 136.1±34.7 mg/dl, 125.4±67.0  mg/dl, baseline and 6th-month p<0.001, baseline and 12th-month p<0.001) and daily dose of insulin (respectively; 102.9±29.0 Unit, 73.2±18.2 U,  63.7±20.3 Unit, baseline and 6th-month p<0.001, baseline and 12th-month p<0.001) at the end of week 24 and 52. CONCLUSIONS: Based on real-world data, this study demonstrated that IDegAsp BID-Plus treatment provides rapid and sustainable blood glucose control with lower insulin doses and fewer injections than previous intensive insulin therapy.

Optimizing The Daily Units Of Insulin; Insulin Degludec Aspart Versus Premixed Insulin Aspart In The Standard Of Care Regimen For Type 2 Diabetics.

BACKGROUND: This study aimed to evaluate the impact of Insulin Degludec Aspart on daily insulin dose in comparison with premixed insulin aspart. METHODS: It was a Quasi-Experimental study conducted in the Department of Pharmacology, Army Medical College, National University of Medical Sciences, Rawalpindi and the Department of Medicine, Pak Emirates Military Hospital, Rawalpindi. One hundred and twenty participants with documented type 2 diabetes, taking premixed insulin aspart therapy were enrolled in the study. Sixty participants were substituted with insulin degludec aspart from premixed insulin aspart. Daily units of insulin were recorded for 12 weeks and compared for both groups. SPSS version 26 was used for analysing the study results. RESULTS: Participants of the insulin degludec aspart group showed a significant reduction in the daily insulin dose compared to the premixed insulin aspart group. Fifty-two units per day were administered in the participants of the premixed insulin aspart patients while insulin degludec aspart participants received 40 units of median daily insulin dose (p-value<0.001). CONCLUSIONS: Insulin degludec aspart proved superior to premixed insulin aspart in a reduction in the daily dose of insulin with insulin degludec aspart.

Faster-acting insulin aspart reduces glycaemic variability in sensor-augmented pump treated type 1 diabetes patients.

AIM: To evaluate the effect of faster aspart over glycaemic variability in type 1 diabetes (T1D) patients treated with sensor-augmented pump (SAP) in a real-world scenario. METHODS: Observational study with SAP-treated adult T1D patients treated with faster aspart for three months. The primary endpoint was the mean amplitude of glucose excursions (MAGE). RESULTS: Fifty patients were treated with faster aspart. Eleven patients (23%) withdrew during the follow-up mainly due to worsening of diabetes control (9 patients). Mean age was 41.2 yrs. (range 21-59) and T1D duration 22.4±10.0 yrs. Mean SAP treatment duration was 3.6±3.1 yrs. We detected a reduction of -7.0 (95% CI -1.1, -12.9; p=0.021) in MAGE at the end of the study. Other glycemic variability indices were also improved: standard deviation of mean interstitial glucose (-3mg/dl; 95% CI, -1, -5; p=0.01), CONGA4 (-2.2; 95% CI -0.3, -4.2; p=0.029), CONGA6 (-2.6; 95% CI -0.6, -4.6; p=0.011), GRADE (-0.5; 95% CI -0.1, -0.9; p=0.022), HBGI (-0.7; 95% CI -0.2, -1.3; p=0.013), J-index (-2.9; 95% CI -0.7, -5.0; p=0.011) and MODD (-5.7; 95% CI -1.7, -9.7; p=0.006). A slight reduction in mean glucose management indicator was also detected (-0.14%; 95% CI, -0.02, -0.27; -1.4mmol/mol; 95% CI -0.1, -3.3; p=0.03). CONCLUSIONS: In SAP-treated T1D patients, faster aspart insulin was associated with reduced glycaemic variability, but also a high percentage of dropouts due to worsened glycaemic control.

Comparative efficacy and safety of Gla-300 versus IDegAsp in insulin-naïve people with type 2 diabetes mellitus uncontrolled on oral anti-diabetics.

AIM: To compare the efficacy and safety of insulin glargine-300 once daily (Gla-300) with insulin degludec/aspart (IDegAsp) once daily in patients with type 2 diabetes (T2D) inadequately controlled on oral anti-diabetic drugs (OADs). MATERIALS AND METHODS: A systematic literature review of randomized controlled trials was followed by an indirect treatment comparison of studies involving insulin naïve adults, inadequately controlled [glycated haemoglobin (HbA1c) ≥7.0%] on OADs, who received Gla-300 or IDegAsp once daily. Outcomes of interest were change in HbA1c, blood glucose, weight and insulin dose, as well as incidence and event rate of hypoglycaemia and other adverse events. RESULTS: Four trials with broadly similar baseline patient characteristics were included in the meta-analyses and indirect treatment comparison. At 24-28 weeks, the indirect comparison of Gla-300 to IDegAsp once daily estimated no statistically significant difference for change in HbA1c (%) from baseline [mean difference of 0.10% (95% CI: -0.20, 0.39; p = .52)]; a statistically significant mean difference of -1.31 kg (95% CI: -1.97, -0.65; p < .05) for change in body weight from baseline; statistically significant odds ratios of 0.62 (95% CI: 0.41, 0.93; p < .05) for incidence of any hypoglycaemia; and 0.47 (95% CI: 0.25, 0.87; p < .05) for incidence of anytime confirmed hypoglycaemia (plasma glucose <3.0-3.1 mmol/L). No significant differences were observed for insulin dose and adverse events. CONCLUSION: In insulin-naïve patients with T2D inadequately controlled on OADs, commencing Gla-300 shows a comparable HbA1c reduction, but with significantly less weight gain and a lower incidence of any and confirmed hypoglycaemia compared with commencing IDegAsp.

Hybrid Closed-Loop with Faster Insulin Aspart Compared with Standard Insulin Aspart in Very Young Children with Type 1 Diabetes: A Double-Blind, Multicenter, Randomized, Crossover Study.

We evaluated the use of hybrid closed-loop (HCL) insulin delivery with faster insulin aspart (Fiasp) in very young children with type 1 diabetes (T1D). In a double-blind, multicenter, randomized, crossover study, children aged 2-6 years with T1D underwent two 8-week periods of HCL using CamAPS FX with Fiasp and standard insulin aspart (IAsp), in random order. Primary endpoint was between-treatment difference in time in target range 3.9-10.0 mmol/L. We randomized 25 participants: mean (±standard deviation) age 5.1 ± 1.3 years, baseline HbA1c 55 ± 9 mmol/mol. Time in range was not significantly different between interventions (64% ± 9% vs. 65% ± 9% for HCL with Fiasp vs. IAsp; mean difference -0.33% [95% confidence interval: -2.13 to 1.47; P = 0.71]). There was no significant difference in time with glucose <3.9 mmol/L. No post-randomization severe hypoglycemia or diabetic ketoacidosis events occurred. Use of Fiasp with CamAPS FX HCL demonstrated no significant difference in glycemic outcomes compared with IAsp in very young children with T1D. Clinical trials registration: NCT04759144.

Maximizing Glycemic Benefits of Using Faster Insulin Formulations in Type 1 Diabetes: In Silico Analysis Under Open- and Closed-Loop Conditions.

Background: Ultrarapid-acting insulin analogs that could improve or even prevent postprandial hyperglycemia are now available for both research and clinical care. However, clear glycemic benefits remain elusive, especially when combined with automated insulin delivery (AID) systems. In this work, we study two insulin formulations in silico and highlight adjustments of both open-loop and closed-loop insulin delivery therapies as a critical step to achieve clinically meaningful improvements. Methods: Subcutaneous insulin transport models for two faster analogs, Fiasp (Novo Nordisk, Bagsværd, Denmark) and AT247 (Arecor, Saffron Walden, United Kingdom), were identified using data collected from prior clamp experiments, and integrated into the UVA/Padova type 1 diabetes simulator (adult cohort, N = 100). Pump therapy parameters and the aggressiveness of our full closed-loop algorithm were adapted to the new insulin pharmacokinetic and pharmacodynamic profiles through a sequence of in silico studies. Finally, we assessed these analogs' glycemic impact with and without modified therapy parameters in simulated conditions designed to match clinical trial data. Results: Simply switching to faster insulin analogs shows limited improvements in glycemic outcomes. However, when insulin acceleration is accompanied by therapy adaptation, clinical significance is found comparing time-in-range (70-180 mg/dL) with Aspart versus AT247 in open-loop (+5.1%); and Aspart versus Fiasp (+5.4%) or AT247 (+10.6%) in full closed-loop with no clinically significant differences in the exposure to hypoglycemia. Conclusion: In silico results suggest that properly adjusting intensive insulin therapy profiles, or AID tuning, to faster insulin analogs is necessary to obtain clinically significant improvements in glucose control.

Insulin degludec versus insulin detemir, both in combination with insulin aspart, in the treatment of pregnant women with type 1 diabetes (EXPECT): an open­label, multinational, randomised, controlled, non-inferiority trial.

BACKGROUND: Insulin degludec (degludec) is a second-generation basal insulin with an improved pharmacokinetic-pharmacodynamic profile compared with first-generation basal insulins, but there are few data regarding its use during pregnancy. In this non-inferiority trial, we aimed to compare the efficacy and safety of degludec with insulin detemir (detemir), both in combination with insulin aspart (aspart), in pregnant women with type 1 diabetes. METHODS: This open-label, multinational, randomised, controlled, non-inferiority trial (EXPECT) was conducted at 56 sites (hospitals and medical centres) in 14 countries. Women aged at least 18 years with type 1 diabetes who were between gestational age 8 weeks (+0 days) and 13 weeks (+6 days) or planned to become pregnant were randomly assigned (1:1), via an interactive web response system, to degludec (100 U/mL) once daily or detemir (100 U/mL) once or twice daily, both with mealtime insulin aspart (100 U/mL), all via subcutaneous injection. Participants who were pregnant received the trial drug at randomisation, throughout pregnancy and until 28 days post-delivery (end of treatment). Participants not pregnant at randomisation initiated the trial drug before conception. The primary endpoint was the last planned HbA1c measurement before delivery (non-inferiority margin of 0·4% for degludec vs detemir). Secondary endpoints included efficacy, maternal safety, and pregnancy outcomes. The primary endpoint was assessed in all randomly assigned participants who were pregnant during the trial. Safety was assessed in all randomly assigned participants who were pregnant during the trial and exposed to at least one dose of trial drug. This study is registered with ClinicalTrials.gov, NCT03377699, and is now completed. FINDINGS: Between Nov 22, 2017, and Nov 8, 2019, from 296 women screened, 225 women were randomly assigned to degludec (n=111) or detemir (n=114). Mean HbA1c at pregnancy baseline was 6·6% (SD 0·6%; approximately 49 mmol/mol; SD 7 mmol/mol) in the degludec group and 6·5% (0·8%; approximately 48 mmol/mol; 9 mmol/mol) in the detemir group. Mean last planned HbA1c measurement before delivery was 6·2% (SE 0·07%; approximately 45 mmol/mol; SE 0·8 mmol/mol) in the degludec group and 6·3% (SE 0·07%; approximately 46 mmol/mol; SE 0·8 mmol/mol) in the detemir group (estimated treatment difference -0·11% [95% CI -0·31 to 0·08]; -1·2 mmol/mol [95% CI: -3·4 to 0·9]; pnon-inferiority<0·0001), confirming non-inferiority. Compared with detemir, no additional safety issues were observed with degludec. INTERPRETATION: In pregnant women with type 1 diabetes, degludec was found to be non-inferior to detemir.

Performance of Fast-Acting Aspart Insulin as Compared to Aspart Insulin in Insulin Pump for Managing Type 1 Diabetes Mellitus: A Meta-Analysis.

BACKGROUND: No meta-analysis has analysed efficacy and safety of fast-acting aspart insulin (FIAsp) with insulin pump in type 1 diabetes mellitus (T1DM). METHODS: Electronic databases were searched for randomised controlled trials (RCTs) involving T1DM patients on insulin pump receiving FIAsp in intervention arm, and placebo/active comparator insulin in control arm. Primary outcome was to evaluate changes in 1- and 2-hour post-prandial glucose (1hPPG and 2hPPG). Secondary outcomes were to evaluate alterations in percentage time with blood glucose <3.9 mmol/L (hypoglycaemia), time in range (TIR) blood glucose 3.9 to 10 mmol/L, insulin requirements and adverse events. RESULTS: Data from four RCTs involving 640 patients was analysed. FIAsp use in insulin pump was associated with significantly greater lowering of 1hPPG (mean difference [MD], -1.35 mmol/L; 95% confidence interval [CI], -1.72 to -0.98; P<0.01; I2=63%) and 2hPPG (MD, -1.19 mmol/L; 95% CI, -1.38 to -1.00; P<0.01; I2=0%) as compared to controls. TIR was comparable among groups (MD, 1.06%; 95% CI, -3.84 to 5.96; P=0.67; I2=70%). Duration of blood glucose <3.9 mmol/L was lower in FIAsp group, approaching significance (MD, -0.91%; 95% CI, -1.84 to 0.03; P=0.06; I2=0%). Total hypoglycaemic episodes (risk ratio [RR], 1.35; 95% CI, 0.55 to 3.31; P=0.51; I2=0%), severe hypoglycaemia (RR, 2.26; 95% CI, 0.77 to 6.66; P=0.14), infusion site reactions (RR, 1.35; 95% CI, 0.63 to 2.93; P=0.77; I2=0%), and treatment-emergent adverse events (RR, 1.13; 95% CI, 0.80 to 1.60; P=0.50; I2=0%) were comparable. CONCLUSION: FIAsp use in insulin pump is associated with better post-prandial glycaemic control with no increased hypoglycaemia or glycaemic variability.

Findings for iGlarLixi versus BIAsp 30 confirmed in groups of people with type 2 diabetes with different biomedical characteristics.

AIM: To report prespecified and post hoc analyses of the SoliMix dataset exploring the impact of baseline participant characteristics on the original SoliMix study outcomes, to enable informed treatment choices for people with different biomedical characteristics. METHODS: SoliMix (EudraCT 2017-003370-13) compared once-daily iGlarLixi (a fixed-ratio combination of insulin glargine 100 U/mL and the glucagon-like peptide-1 receptor agonist lixisenatide) with twice-daily BIAsp 30 (30% insulin aspart and 70% insulin aspart protamine). In this analysis, the original primary outcomes of noninferiority of iGlarLixi versus BIAsp 30 in terms of glycated haemoglobin (HbA1c) change and superiority in terms of body weight change, together with change in basal insulin dose and hypoglycaemia outcomes, were investigated by baseline age, duration of diabetes, insulin dose, HbA1c level, body mass index (BMI), and renal function. RESULTS: No evidence of difference in comparative treatment effect was detected across baseline age, duration of diabetes, insulin dose, HbA1c level, BMI and renal function subgroups for any endpoint (all heterogeneity P > 0.05), except American Diabetes Association Level 2 hypoglycaemia event rate when stratified by insulin dose (P = 0.011), which may be a chance difference given multiple testing and the small numbers of Level 2 events. CONCLUSIONS: Treatment effects of iGlarLixi were consistent irrespective of baseline HbA1c, insulin dose, BMI, age, duration of diabetes and renal function, supporting the use of iGlarLixi as an efficacious and well-tolerated treatment option in people with type 2 diabetes with a wide range of biomedical characteristics.

Hybrid Closed-Loop Control with Ultrarapid Lispro Compared with Standard Insulin Aspart and Faster Insulin Aspart: An In Silico Study.

OBJECTIVE: There is room for improvement in the performance of closed-loop regulation algorithms during the prandial period. This in silico study evaluated the efficiency and safety of ultrarapid lispro insulin using the Diabeloop DBLG1® algorithm. METHODS: We modeled the insulin profile of URLi according to literature data and integrated it to the model used within a simulation platform built from a 60 patients' virtual cohort. We then ran the DBLG1® algorithm in silico with various meal intakes using modeled URLi, Aspart and Faster Aspart. The primary endpoints were glucose metrics (time in 70-180 mg/dL range and time below range). RESULTS: When insulin time constant values were tuned, time in 70-180 mg/dL range was 69.4 [61.1-75.6] (Aspart) vs 74.7 [65.5-81.5] (URLi). Glucose coefficient of variation was reduced from 34.1 [29.7-37.8] to 28.4 [25.7-34.6]. Time below 70 mg/dL and 54 mg/dL were significantly reduced with URLi, whether or not DBLG1 was specifically tuned to this insulin. Metrics with Faster Aspart were intermediate and did not significantly differ from URLi. CONCLUSIONS: This simulation study performed on a virtual T1D population suggests that the use of URLi within an unmodified closed-loop DBLG1 regulation algorithm is safe and, with DBLG1 being tuned to this specific insulin type, improved the regulation performances as compared with Aspart. This fact supports the use of such an insulin in clinical investigations.

The efficacy and safety of GP40081 (insulin aspart biphasic 30) compared with NovoMix® 30 in Type 2 diabetes patients.

Aim: To evaluate the safety and efficacy of insulin Aspart-Mix biosimilar candidate GP40081 (GP-Asp30) compared with NovoMix® 30 (NN-Asp30). Materials & methods: In a randomized open-label, active-controlled, 26-week non-inferiority clinical trial 264 patients with Type 2 diabetes mellitus were randomized 1:1 to receive once-daily GP-Asp30 or NN-Asp30. The primary safety end point was the immune response rate. Efficacy outcomes were a mean change in HbA1c (primary), frequency of achieving a glycemic g fasting plasma glucose levels, 7-point glucose profiles, and insulin doses. Results: The immune response developed in 10/126 (8%) participants in the GP-Asp30 group and in 10/125 (8%) participants in the NN-Asp30 group (p = 1.000). The mean difference in HbA1c change between groups was 0.12 (95%CI [-0.14, 0.38]). Other secondary efficacy and safety outcomes weren't statistically different between the two groups. Conclusion: GP-Asp30 demonstrated similar safety and efficacy compared with NN-Asp30 and may be considered a biosimilar insulin.
