Abstract
INTRODUCTION Considerable efforts to standardize continuous glucose monitoring (CGM) have occurred in recent years. The aim was to perform an analysis of clinical studies in clinicaltrials.gov to evaluate trends in CGM endpoint adoption. METHODS Clinicaltrials.gov was searched for studies of drugs, devices and combination products containing CGM terms posted from 2012 to 2023. 1269 studies were returned and 954 were excluded. 315 studies were divided into two periods (P1 [2012-2017] and P2 [2018-2023]) and differences analyzed using descriptive statistics and two-tailed t tests. RESULTS There was a significant 60.3% increase in total clinical studies from P1 (121) to P2 (194). Phase 2 and Phase 3 Studies both saw significant increases of 125.8 and 169.2%, respectively, in P2. Adult-only studies predominated in both periods, with a 40.4% increase in P2. Studies that included pediatric populations, although smaller in number, increased significantly. Most studies were nonindustry-funded, and studies in this category saw a significant 80.0% increase in P2. However, industry-only funded studies also increased significantly by 78.4% in P2 in the same period. Studies of type 1 diabetes (T1DM) and type 2 diabetes (T2DM) increased by 55.8% and 26.9%, respectively, but increases were not statistically significant. Studies of nondiabetes-related indications did increase significantly (233.3%). 27.6% of studies used CGM-derived metrics as primary endpoints (PE). Studies that used time in range (TIR) increased by 222.4% in P2, which was significant. Conversely studies that used mean amplitude of glycemic excursions (MAGE) decreased significantly by 71.3%. CONCLUSION Our data provide evidence of significant increases in the application of CGM endpoints in clinical studies in the last six years, including studies with TIR as the PE. Increases have been driven largely by academia, but our data show that industry is starting to follow suit. The significant increase in studies that included pediatrics is encouraging.

Abstract
The introduction of continuous glucose monitoring inaugurated a new era in clinical practice by shifting the characterization of glycemic control from HbA1c to novel metrics. The one that gained widespread attention over the past decades was glycemic variability (GV), which typically refers to peaks and nadirs of blood glucose measured over a given time interval. GV can be dichotomized into two main categories: short-term and long-term. Short-term GV reflects within-day and between-day glycemic oscillations, and its contribution to diabetic complications remains an enigma. In this review, we summarize the available data about short-term GV and its possible association with both microvascular and macrovascular complications, evaluating different pathogenic mechanisms and demonstrating nonpharmaceutical, as well as pharmaceutical, therapeutic interventions.

Abstract
Objectives: To study real-world effect of switching to Insulin Glargine 300 U/mL (Gla-300) on glucose metrics in people with type 1 diabetes. Methods: This retrospective secondary-use study compared 151 adults who switched to Gla-300 from first-generation long-acting insulins (Switchers) to 281 propensity-score matched controls (Non-switchers) who continued first-generation long-acting insulins. Primary endpoint was difference in time in range (TIR) evolution. A fictive "switching" date was assigned to Non-switchers to facilitate between-group comparisons. Results: In the period before switching, TIR decreased numerically for people in whom Gla-300 was eventually initiated (-0.05%/month [-0.16 to 0.07]), while it increased for matched controls (0.08%/month [0.02 to 0.015]; between-group difference P = 0.047). After Gla-300-initiation, Switchers had similar TIR increase compared to Non-switchers (P = 0.531). Switchers used higher basal dose than before switch (Δ0.012 U/[kg·d] [0.006 to 0.018]; P < 0.0001). Conclusion: In real-life, Gla-300 was typically initiated in people where TIR was decreasing, which was reversed after switch using slightly higher basal insulin dose. ClinicalTrials: ClinicalTrials.gov number NCT05109520.

Frequency of hypoglycaemia with basal insulin treatments in adults with type 1 diabetes treated with basal-bolus insulin regimens in treat-to-target trials: A narrative review. Diabet Med 2024; 41:e15339. [PMID: 38679910 DOI: 10.1111/dme.15339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 04/12/2024] [Accepted: 04/16/2024] [Indexed: 05/01/2024]
Abstract
AIM To summarise, in a narrative review, published data on hypoglycaemia occurrence with basal insulin therapy in adults with type 1 diabetes treated with basal-bolus insulin regimens in treat-to-target randomised controlled trials. METHODS Data were included from 21 eligible trials, which mainly used self-measured blood glucose or plasma glucose to detect hypoglycaemia. RESULTS All-day self-measured blood glucose or plasma glucose level 2 (glucose threshold of 3.1 or 3.0 mmol/L) and level 3 (severe, requiring assistance) hypoglycaemic events were reported, respectively, by a range of 69.0%-97.5% and 0%-13.4% adults when receiving basal-bolus insulin therapy, with rates of 10.6-68.1 and 0.0-0.4 events per patient-year of exposure, respectively. Hypoglycaemia rates measured using continuous glucose monitoring (three studies) were numerically, yet consistently, higher than with either other method, except when limiting to symptomatic events. Nocturnal hypoglycaemia rates were generally less than 30% of the equivalent all-day rates. CONCLUSIONS Differences across the studies in design (e.g., titration targets) and participant characteristics hindered comparison of hypoglycaemia rates by insulin formulation. Consequently, few trends were identified by insulin formulation, study methodology or individuals' characteristics, suggesting that further research is required to identify treatment strategies that facilitate development of individualised recommendations to lower hypoglycaemia risk. These findings are useful to understand hypoglycaemia risk with available basal insulin therapies when used in a multiple daily injection regimen, as well as to provide context for the results of ongoing and future clinical trials, including those for two once-weekly basal insulins, insulin icodec and basal insulin Fc.

Abstract
BACKGROUND Over the past two decades, insulin glargine 100 U/mL (Gla-100) has emerged as the "standard of care" basal insulin for the management of type 1 diabetes mellitus (T1DM). Both formulations, insulin glargine 100 U/mL (Gla-100) and glargine 300 U/mL (Gla- 300) have been extensively studied against various comparator basal insulins across various clinical and real-world studies. In this comprehensive article, we reviewed the evidence on both insulin glargine formulations in T1DM across clinical trials and real-world studies. METHODS Evidence in T1DM for Gla-100 and Gla-300 since their approvals in 2000 and 2015, respectively, were reviewed. RESULTS Gla-100 when compared to the second-generation basal insulins, Gla-300 and IDeg-100, demonstrated a comparable risk of overall hypoglycemia, but the risk of nocturnal hypoglycemia was higher with Gla-100. Additional benefits of Gla-300 over Gla-100 include a prolonged (>24- hours) duration of action, a more stable glucose-lowering profile, improved treatment satisfaction, and greater flexibility in the dose administration timing. CONCLUSION Both glargine formulations are largely comparable to other basal insulins in terms of glucose-lowering properties in T1DM. Further, risk of hypoglycemia is lower with Gla-100 than Neutral Protamine Hagedorn but comparable to insulin detemir.

Abstract
AIM To compare the clinical efficacy and safety of glargine-U100 (Lantus/Gla-100) with glargine-U300 (Toujeo/Gla-300) in adult patients with type 2 diabetes (T2D) and type 1 diabetes (T1D). MATERIALS AND METHODS A literature search on Gla-300/Gla-100 in diabetes management was conducted using the MEDLINE/Embase/Cochrane databases from inception to 10 January 2021. Eligible studies considered for inclusion were parallel-design, randomized controlled trials (RCTs). The Cochrane risk-of-bias tool was used to evaluate the quality of the included studies. The random-effects model was applied for interpretation of the results. RESULTS Of 5348 records screened, 592 were assessed for eligibility and 15 RCTs were considered for data extraction and meta-analysis (T2D [N = 10; n = 7082]; T1D [N = 5; n = 2222]). In patients with T1D, all safety parameters were comparable between Gla-100 and Gla-300. In T2D, statistically significant differences were observed in favour of Gla-300 over Gla-100 for nocturnal and total hypoglycaemia. For efficacy parameters, a statistically and clinically significant difference favouring Gla-100 in basal insulin dose requirement was observed for both T2D and T1D. Change in HbA1c showed a statistically but not clinically significant reduction with Gla-100 compared with Gla-300 in T1D. Statistically significant but clinically less relevant differences favoured Gla-300 for control of body weight in T1D and T2D and Gla-100 for fasting blood glucose in T2D. CONCLUSIONS Gla-100 and Gla-300 had comparable efficacy and safety profiles in both T1D and T2D populations. Gla-300 showed a lower risk of nocturnal and total hypoglycaemia, significant in insulin-experienced/exposed patients with T2D. Patients on Gla-300 required significantly more units of insulin daily than the Gla-100 group to achieve equivalent efficacy.

BMJ Open Diabetes Res Care 2022; 10:10/4/e002898. [PMID: 36007982 PMCID: PMC9422797 DOI: 10.1136/bmjdrc-2022-002898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 07/09/2022] [Indexed: 11/04/2022] Open
Abstract
Short-term glycemic variability is associated with the risk of hypoglycemia and hyperglycemia in people living with type 1 diabetes and can potentially affect clinical outcomes. Continuous glucose monitoring (CGM) is of increasing importance to evaluate glycemic variability in greater detail. Specific metrics for assessing glycemic variability were proposed, such as the SD of mean glucose level and associated coefficient of variation, and time in target glucose range to guide study designs, therapy and allow people with diabetes more transparency in interpreting their own CGM data. Randomized controlled trials (RCT) and real-world evidence provide complementary information about the efficacy/effectiveness and safety of interventions. Insulin glargine 300 U/mL (Gla-300) has a longer lasting and less variable action than insulin glargine U100 (Gla-100) with a lower risk of hypoglycemia. While insulin degludec U100 (iDeg-100) was associated with lower glucose values but more time below range in one randomized study compared with Gla-300, Gla-300 was associated with a higher per cent time in range, but also above the therapeutic range. However, a real-world study did not find differences during the day between Gla-300 and iDeg-100. The upcoming InRange RCT is the first head-to-head comparison of Gla-300 with iDeg-100 using CGM in an international population using CGM metrics as the primary endpoint. The non-interventional COMET-T real-world study will determine the real-world effectiveness of Gla-300 using CGM metrics and cover a broad spectrum of clinical practice decisions irrespective of the prior basal insulin.

Abstract
BACKGROUND Clinical differences between degludec U100 (Deg-100) and glargine U300 (Gla-300) in type 1 diabetes (T1D) were unknown. AIM To indirectly compare the safety, efficacy, and cost-effectiveness between Deg-100 and Gla-300 in T1D adults via systematic review. METHOD Medline, the Cochrane Library, ClinicalTrials.gov, and Google Scholar were searched (October 2021). Randomized controlled trials comparing Deg-100 or Gla-300 vs. glargine U100 in T1D adults (follow-up ≥ 12 weeks) were selected and analyzed using a frequentist network meta-analysis. Cost-effectiveness analysis (CEA) was conducted over a 1-year time horizon from societal perspectives. RESULTS Nine trials were included. Efficacy analysis suggested that Deg-100 was non-inferior to Gla-300 in reducing HbA1c (MD 0.03 [95% CI - 0.09 to 0.15]; P = 0.60), FPG (MD - 1.12 [- 2.19 to - 0.04]; P = 0.04), and pre-breakfast SMBG (MD - 0.71 [- 1.46 to 0.03]; P = 0.06). Safety analysis suggested that Deg-100 appeared to have lower rates of both severe (HR 0.44 [0.25-0.78]; P = 0.005) and nocturnal severe (HR 0.19 [0.08-0.44]; P < 0.001) hypoglycemia, with lower total (MD - 0.07 [- 0.13 to - 0.01]; P = 0.02) and basal (MD - 0.08 [- 0.12 to - 0.04]; P < 0.001) insulin doses compared with Gla-300. No significant differences were observed for other hypoglycemia outcomes, adverse events, serious adverse events, bolus insulin dose, and body weight. The CEA showed that Deg-100 appeared to be a dominant treatment in Japan (+ 0.0283 QALYs, ¥26,266 [$228] per patient) and the United States (+ 0.0267 QALYs, $986 per patient). CONCLUSION Low-certainty indirect evidence suggested that Deg-100 appeared to have a favorable reduction in rates of severe hypoglycemia and more cost-effective compared with Gla-300 in T1D adults.

Abstract
AIMS Insulin glargine 300 U/mL (Gla-300) contains the same units versus glargine 100 U/mL (Gla-100) in three-fold lower volume, and higher subcutaneous (SC) doses are required in people with diabetes. To investigate blood glucose (BG) lowering potency, Gla-300 and Gla-100 were compared after intravenous (IV, for 4 h) and SC (for 24 h) injection in healthy Beagle dogs. MATERIALS AND METHODS The dose of 0.15 U/kg Gla-300 and Gla-100 was injected IV in 12 dogs. BG, C-peptide, glucagon and the active metabolite 21A-Gly-human insulin (M1; liquid chromatography-tandem mass spectrometry method) were measured. Twelve other dogs were studied after SC injection of 0.3 U/kg Gla-300 and Gla-100. RESULTS After IV injection, Gla-300 and Gla-100 were equally potent [BG_AUC0-4 h ratio 1.01 (95% confidence interval, 0.94; 1.09)]. After SC injection, BG decreased slower and less with Gla-300. Similar metabolism of Gla-300 and Gla-100 to M1 occurred with IV dosing [M1_AUC0-1 h ratio 0.99 (95% confidence interval, 0.82; 1.22)], but with SC dosing M1_Cmax and AUC0-24h were 44% and 17% lower; mean residency time and bioavailability were 32% longer and 50% lower, with Gla-300. CONCLUSIONS IV Gla-300 and Gla-100 have the equivalent of BG-lowering potency and M1 metabolism. SC Gla-300 has lower M1 bioavailability with a reduced BG-lowering effect and need for greater doses versus Gla-100.

Abstract
BACKGROUND With limited real-world insulin glargine 300 U/mL (Gla-300) data among Japanese patients with type 1 diabetes mellitus (T1DM) available, the authors describe its effectiveness and safety in Japanese T1DM patients switching to Gla-300. RESEARCH DESIGN AND METHODS X-STAR was a 12-month prospective, observational, post-marketing study in Japanese patients with diabetes mellitus from 2015 to 2018: insulin-experienced T1DM patients initiating Gla-300 were analyzed. RESULTS Of 774 patients, mean (±standard deviation) HbA1c (%) and fasting plasma glucose (mg/dL) decreased from 8.27 ± 1.55 to 8.15 ± 1.35 (by -0.12 ± 1.30 [p = 0.013]) and 167.9 ± 92.6 to 153.9 ± 70.9 (by -13.9 ± 103.8 [p = 0.067]) from baseline to month 12, respectively. A total of 16.3% achieved HbA1c <7.0% at month 12. Gla-300 dose increased by 1.13 ± 3.18 U/day (0.02 ± 0.05 U/kg/day) (p < 0.001), with a + 0.22 ± 2.70 (p = 0.037) body-weight change (kg) from baseline 60.83 ± 12.81 to 12-month 61.06 ± 12.89. Adverse drug reactions (ADRs) and serious ADRs occurred in 9.82% and 0.78% of the patients, respectively. Hypoglycemia was the most common ADR (9.30%). In total, 88.9% adhered to Gla-300 administration schedules, whereas <40% adhered to exercise and dietary instructions, respectively. CONCLUSIONS Gla-300 showed no unprecedented safety concerns for insulin-experienced T1DM patients in Japanese clinical settings. Our results provide insights into strategies for blunted Gla-300 up-titration dose, despite insufficient HbA1c control and lifestyle modification.

Abstract
The aim of this study was to establish the effects of clinical doses of Gla-300 versus Gla-100 on suppression of glucagon, lipolysis, and ketogenesis in type 1 diabetes mellitus (T1DM). Eighteen persons with T1DM (age 40 ± 12 years, diabetes duration 26 ± 12 years, body mass index 23.4 ± 2 kg/m2, A1C 7.19% ± 0.52% [55 ± 6 mmol/mol]) were studied after 3 months of titration with Gla-300 and Gla-100 (randomized, crossover design) with a 24-h euglycemic clamp (s.c. injection of individual insulin daily doses used by subjects for previous 2 weeks, Gla-300 0.35 ± 0.08 and Gla-100 0.28 ± 0.07 U/kg). Gla-300 resulted in (1) less increase in insulin concentration for 0-12 h, but greater insulin concentration in 12-24 h (no differences for 24 h); (2) greater glucagon suppression; (3) greater prehepatic insulin-to-glucagon molar ratio, primarily in 12-24 h (ratio 1.78, 90% confidence intervals [CIs] 1.5-2.1); and (4) lower 24-h free fatty acid (0.81; 90% CI 0.73-0.89), glycerol (0.78; 90% CI 0.65-0.94), and β-hydroxybutyrate (0.72; 90% CI 0.58-0.90). Over the 24 h postinjection, as compared with Gla-100, clinical doses of Gla-300 exhibit greater suppressive effects on glucagon, lipolysis, and ketogenesis, whereas the effects on glucose metabolism are equivalent.
