Abstract
Therapeutic proteins have been employed for centuries and reached approximately 50 % of all drugs investigated. By 2023, they represented one of the top 10 largest-selling pharma products ($387.03 billion) and are anticipated to reach around $653.35 billion by 2030. Growth hormones, insulin, and interferon (IFN α, γ, and β) are among the leading applied therapeutic proteins with a higher market share. Protein-based therapies have opened new opportunities to control various diseases, including metabolic disorders, tumors, and viral outbreaks. Advanced recombinant DNA biotechnology has offered the production of therapeutic proteins and peptides for vaccination, drugs, and diagnostic tools. Prokaryotic and eukaryotic expression host systems, including bacterial, fungal, animal, mammalian, and plant cells usually applied for recombinant therapeutic proteins large-scale production. However, several limitations face therapeutic protein production and applications at the commercial level, including immunogenicity, integrity concerns, protein stability, and protein degradation under different circumstances. In this regard, protein-engineering strategies such as PEGylation, glycol-engineering, Fc-fusion, albumin conjugation, and fusion, assist in increasing targeting, product purity, production yield, functionality, and the half-life of therapeutic protein circulation. Therefore, a comprehensive insight into therapeutic protein research and findings pave the way for their successful implementation, which will be discussed in the current review.

Insulin Degludec in People with Type 2 Diabetes in China: A Non-interventional, Retrospective Chart Review Study (CN-TREAT). Diabetes Ther 2024; 15:725-739. [PMID: 38438707 PMCID: PMC10942918 DOI: 10.1007/s13300-024-01533-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 01/16/2024] [Indexed: 03/06/2024] Open
Abstract
INTRODUCTION Insulin degludec (degludec), an ultra-long-acting basal insulin analogue, provides equivalent glycemic control to other basal insulin analogues, with lower risk of hypoglycemia and flexible dosing. Chinese TREsiba AudiT (CN-TREAT) investigated outcomes with degludec in people with type 2 diabetes (T2D) in routine clinical practice in China. METHODS This was a retrospective chart review study in adults with T2D initiating or switching to degludec at 50 sites in China between January 2020 and July 2021. The primary endpoint was change in glycated hemoglobin (HbA1c) from baseline to end of study (EOS; week 20). Secondary endpoints included change from baseline to EOS in fasting plasma glucose (FPG), self-measured plasma glucose (SMPG), daily insulin dose, and rate of hypoglycemia. RESULTS Data from 936 participants were included (499 insulin-naïve; 437 insulin-experienced). Mean (95% confidence interval [CI]) HbA1c change from baseline to EOS was - 1.48%-points (- 1.57; - 1.38; P < 0.0001) overall: - 1.95%-points (- 2.08; - 1.81; P < 0.0001) in insulin-naïve participants and - 0.95%-points (- 1.08; - 0.82; P < 0.0001) in insulin-experienced participants. Mean (95% CI) changes in FPG and SMPG were - 2.27 mmol/L (- 2.69; - 1.85; P < 0.0001) and - 2.89 mmol/L (- 3.52; - 2.25; P < 0.0001), respectively, with similar reductions in insulin-naïve and insulin-experienced subgroups. Rate of hypoglycemia did not change statistically significantly from baseline to EOS overall, or in insulin-experienced participants, except when adjusted for baseline hypoglycemia. Basal insulin dose did not change statistically significantly in insulin-experienced participants. CONCLUSION In routine clinical practice in China, initiation or switching to degludec was associated with improvements in glycemic control in people with T2D, with no increased risk of hypoglycemia. TRIAL REGISTRATION ClinialTrials.gov, NCT04227431.

Abstract
2021 marks the 100th anniversary of the discovery of insulin, an event that forever changed the lives of people with diabetes mellitus. At present patients around the world experience the miracle of insulin therapy every day. A disease that used to kill children and teenagers in 2 years in 1920 has become a disease that can be controlled with a possibility to lead a long productive life. Over the past century, the great discovery of Banting, Best and Collip has forever changed the world and saved millions of lives. This review is devoted to the history of the development of insulin and its further improvement: from the moment of discovery to the present days. Various generations of insulin are considered: from animals to modern ultrashort and basal analogues. The article ends with a brief review of current trends in the development of new delivery methods and the development of new insulin molecules. Over the past century, insulin therapy has come a long way, which has significantly improved the quality of life of our patients. But research is actively continuing, including in the field of alternative methods of insulin delivery, which are more convenient for the patient, as well as in the development of «smart» molecules that will have a glucose-dependent effect.

Abstract
Insulin therapy is the mainstay to treat diabetes characterizedd by hyperglycemia. However, its short half-life of only 4-6 min limits its effectiveness in treating chronic diabetes. Advances in recombinant DNA technology and protein engineering have led to several insulin analogue products that have up to 42 h of glycemic control. However, these insulin analogues still require once- or twice-daily injections for optimal glycemic control and have poor patient compliance and adherence issues. To achieve insulin release for more than one day, different injectable delivery systems including microspheres, in situ forming depots, nanoparticles and composite systems have been developed. Several of these delivery systems have advanced to clinical trials for once-weekly insulin injection. This review comprehensively summarizes the developments of injectable insulin analogs and delivery systems covering the whole field of injectable long-lasting insulin technologies from prototype design, preclinical studies, clinical trials to marketed products for the treatment of diabetes.

Abstract
Aims: In the ULTRAFLEXI-1 study, we compared basal insulin Glargine 300 U/mL (IGlar U300) and insulin Degludec 100 U/mL (IDeg U100) for time below range <70 mg/dL (TBR<70; 3.9 mmol/L) in two different doses (100% and 75% of the regular dose) when used around spontaneous exercise sessions in adults with type 1 diabetes. Methods: A randomized, single-center, four-period, cross-over trial was performed and in each of the four 2-weeks-periods, participants attended six spontaneous 60 min moderate-intensity evening cycle ergometer exercise sessions. The basal insulin administered on the exercise days were IGlar U300 100% or 75% of the regular dose or IDeg U100 100% or 75%, respectively (morning injection). The primary outcome was the TBR<70 during the 24 h postexercise periods of the six spontaneous exercise sessions in the four trial arms and was analyzed in hierarchical order using the repeated measures linear mixed model. Results: Twenty-five people with type 1 diabetes were enrolled (14 males) with a mean age of 41.4 ± 11.9 years and an HbA1c of 7.5% ± 0.8% (59 ± 9 mmol/mol). The mean ± standard error of mean TBR<70 during the 24 h periods following the exercise sessions was 2.71% ± 0.51% for IGlar U300 (100%) and 4.37% ± 0.69% for IDeg U100 (100%) (P = 0.023) as well as 2.28% ± 0.53% for IGlar U300 and 2.55% ± 0.58% for IDeg U100 when using a 75% dose on exercise days (P = 0.720). Time in glucose range70-180 was the highest in the IDeg U100 (100%) group. Conclusions: TBR<70 within the first 24 h after spontaneous exercise sessions was significantly lower when receiving IGlar U300 compared to IDeg U100 when a regular basal dose was administered.

Abstract
BACKGROUND: Effective glycaemic control remains the most important task in managing the risks of Diabetes type 2 complications development. In this regard, the choice of insulin preparations with minimal variability of action is of utmost importance since this approach allows achieving the maximum treatment effectiveness and adequate safety level.AIM: The aim of this study was to investigate insulin degludec treatment effect on glycemic control in adult patients with Diabetes Mellitus (DM) type 2 in a real-world clinical setting in the Russian Federation.MATERIALS AND METHODS: The open prospective study was conducted in 2020–2021 in 35 clinical centers in 31 cities of the Russian Federation. The study included adult patients with type 2 DM treated according to Russian routine clinical practice. The prospective follow-up period was 26 weeks. The main study endpoints were changes in HbA1c level, fasting plasma glucose, insulin daily doses, number, and characteristics of different types of hypoglycaemia episodes and adverse events (AEs), and patient preferences compared to previous treatment.RESULTS: The study enrolled 494 patients. By the end of follow-up period:The mean HbA1c decrease was 1.6% (p<0.0001).Fasting plasma glucose level decreased by 3.4 mmol/L (p<0.0001).Daily basal and prandial insulin doses decreased by 1.6 IU/day (p<0.0001) and 2.1 IU/day (p<0.01), respectively.Severe episodes of hypoglycemia did not occur, while the incidence of nonsevere episodes decreased significantly.76 patients (15.4%) had 105 AEs, of which 41 (in 33 patients, 6.7%) were serious.COVID-19 was the most frequent AE reported in 21 patients (4.3%).Only in one case insulin degludec was withdrawn due to the patient’s pregnancy and the AEs that arose from it.Most patients (98.6%) preferred insulin degludec to previous treatment.CONCLUSION: The study demonstrated a statistically significant improvement in glycemic control, accompanied by basal insulin dose decrease combined with the absence of severe episodes of hypoglycemia, and significant decrease of nonsevere episodes (total and nocturnal). These results led to a large proportion of patients wanting to continue insulin degludec treatment preferring the medicine over previous treatment.

Abstract
The year 2021 marks the 100th anniversary of the momentous discovery of insulin. Through years of research and discovery, insulin has evolved from poorly defined crude extracts of animal pancreas to recombinant human insulin and analogues that can be prescribed and administered with high accuracy and efficacy. However, there are still many challenges ahead in clinical settings, particularly with respect to maintaining optimal glycemic control whilst minimizing the treatment-related side effects of hypoglycemia and weight gain. In this review, the chronology of the development of rapid-acting, short-acting, intermediate-acting, and long-acting insulin analogues, as well as mixtures and concentrated formulations that offer the potential to meet this challenge, are summarized. In addition, we also summarize the latest advancements in insulin delivery methods, along with advancement to clinical trials. This review provides insights on the development of insulin treatment for diabetes mellitus that may be useful for clinicians in meeting the needs of their individual patients. However, it is important to note that as of now, none of the new technologies mentioned have superseded the existing method of subcutaneous administration of insulin.

Abstract
The destruction of β-cells of the pancreas leads to either insulin shortage or the complete absence of insulin, which in turn causes diabetes Mellitus. For treating diabetes, many trials have been conducted since the 19th century until now. In ancient times, insulin from an animal's extract was taken to treat human beings. However, this resulted in some serious allergic reactions. Therefore, scientists and researchers have tried their best to find alternative ways for managing diabetes with progressive advancements in biotechnology. However, a lot of research trials have been conducted, and they discovered more progressed strategies and approaches to treat type I and II diabetes with satisfaction. Still, investigators are finding more appropriate ways to treat diabetes accurately. They formulated insulin analogs that mimic the naturally produced human insulin through recombinant DNA technology and devised many methods for appropriate delivery of insulin. This review will address the following questions: What is insulin preparation? How were these devised and what are the impacts (both positive and negative) of such insulin analogs against TIDM (type-I diabetes mellitus) and TIIDM (type-II diabetes mellitus)? This review article will also demonstrate approaches for the delivery of insulin analogs into the human body and some future directions for further improvement of insulin treatment.

Abstract
Given the fact that diabetes remains a leading cause of end-stage kidney disease (ESKD), multi-aspect approaches anticipating the risk for ESKD and timely correction are crucial. We investigated whether fasting glucose variability (FGV) could anticipate the development of ESKD and identify the population prone to the harmful effects of GV. We included 777,192 Koreans with diabetes who had undergone health examinations more than three times in 2005-2010. We evaluated the risk of the first diagnosis of ESKD until 2017, according to the quartile of variability independent of the mean (VIM) of FG using multivariate-adjusted Cox proportional hazards analyses. During the 8-year follow-up, a total of 7290 incidents of ESKD were found. Subjects in the FG VIM quartile 4 had a 27% higher risk for ESKD compared to quartile 1, with adjustment for cardiovascular risk factors and the characteristics of diabetes. This effect was more distinct in patients aged < 65 years; those with a long duration of diabetes; the presence of hypertension or dyslipidemia; and prescribed angiotensin-converting enzyme inhibitors, metformin, sulfonylurea, α-glucosidase inhibitors, and insulin. In contrast, the relationship between baseline FG status and ESKD risk showed a U-shaped association. FGV is an independent risk factor for kidney failure regardless of FG.

Abstract
Treating and monitoring type 2 diabetes mellitus (T2DM) in NHP can be challenging. Multiple insulin and hypoglycemic therapies and management tools exist, but few studies demonstrate their benefits in a NHP clinical setting. The insulins glargine and degludec are long-acting insulins; their duration of action in humans exceeds 24 and 42 h, respectively. In the first of this study's 2 components, we evaluated whether insulin degludec could be dosed daily at equivalent units to glargine to achieve comparable blood glucose (BG) reduction in diabetic rhesus macaques (Macaca mulatta) with continuous glucose monitoring (CGM) devices. The second component assessed the accuracy of CGM devices in rhesus macaques by comparing time-stamped CGM interstitial glucose values, glucometer BG readings, and BG levels measured by using an automated clinical chemistry analyzer from samples that were collected at the beginning and end of each CGM device placement. The CGM devices collected a total of 21,637 glucose data points from 6 diabetic rhesus macaques that received glargine followed by degludec every 24 h for 1 wk each. Ultimately, glucose values averaged 29 mg/dL higher with degludec than with glargine. Glucose values were comparable between the CGM device, glucometer, and chemistry analyzer, thus validating that CGM devices as reliable for measuring BG levels in rhesus macaques. Although glargine was superior to degludec when given at the same dose (units/day), both are safe and effective treatment options. Glucose values from CGM, glucometers, and chemistry analyzers provided results that were analogous to BG values in rhesus macaques. Our report further highlights critical clinical aspects of using glargine as compared with degludec in NHP and the benefits of using CGM devices in macaques.

Abstract
BACKGROUND Previous research regarding long-term glucose variability over several years which is an emerging indicator of glycemic control in diabetes showed several limitations. We investigated whether variability in long-term fasting plasma glucose (FG) can predict the development of stroke, myocardial infarction (MI), and all-cause mortality in patients with diabetes. METHODS This is a retrospective cohort study using the data provided by the Korean National Health Insurance Corporation. A total of 624,237 Koreans ≥ 20 years old with diabetes who had undergone health examinations at least twice from 2005 to 2008 and simultaneously more than once from 2009 to 2010 (baseline) without previous histories of stroke or MI. As a parameter of variability of FG, variability independent of mean (VIM) was calculated using FG levels measured at least three times during the 5 years until the baseline. Study endpoints were incident stroke, MI, and all-cause mortality through December 31, 2017. RESULTS During follow-up, 25,038 cases of stroke, 15,832 cases of MI, and 44,716 deaths were identified. As the quartile of FG VIM increased, the risk of clinical outcomes serially increased after adjustment for confounding factors including duration and medications of diabetes and the mean FG. Adjusted hazard ratios (95% confidence intervals) of FG VIM quartile 4 compared with quartile 1 were 1.20 (1.16-1.24), 1.20 (1.15-1.25), and 1.32 (1.29-1.36) for stroke, MI and all-cause mortality, respectively. The impact of FG variability was higher in the elderly and those with a longer duration of diabetes and lower FG levels. CONCLUSIONS In diabetes, long-term glucose variability showed a dose-response relationship with the risk of stroke, MI, and all-cause mortality in this nationwide observational study.

Abstract
Insulin is an anabolic hormone essential to glucose homeostasis. Insulin therapy, comprising human insulin (HI) or biosynthetic analogs, is critical for the management of type-1 diabetes and many of type-2 diabetes. However, medication error including non-adapted dose and confusion of insulin type, and misuse, such as massive self-administration or with criminal intent, can have lethal consequences. The aim of this paper is to review the state of knowledge of insulin analysis in biological samples and of the interpretation of insulin concentrations in the situation of insulin-related death investigations. Analytic aspects are considered, as quantification can be strongly impacted by methodology. Immunoanalysis, the historical technique, has a prominent role due to its sensitivity and ease of implementation. Recently, liquid chromatography coupled to mass spectrometry has provided indispensable selectivity in forensic contexts, distinguishing HI, analogs, and degradation products. We review the numerous antemortem (dose, associated pathology, injection-to-death interval, etc.) and postmortem parameters (in corpore degradation, in vitro degradation related to hemolysis, etc.) involved in the interpretation of insulin concentration. The interest and limitations of various alternative matrices providing a valuable complement to blood analysis are discussed. Vitreous humor is one of the most interesting, but the low diffusion of insulin in this matrix entails very low concentrations. Injection site analysis is relevant for identifying which type of insulin was administered. Muscle and renal cortex are matrices of particular interest, although additional studies are required. A table containing most case reports of fatal insulin poisoning published, with analytical data, completes this review. A logic diagram is proposed to highlight analytical issues and the main parameters to be considered for the interpretation of blood concentrations. Finally, it remains a challenge to provide reliable biological data and solid interpretation in the context of death related to insulin overdose. However, the progress of analytical tools is making the "perfect crime" ever more difficult to commit.

Abstract
Protein polysaccharide complexes have been widely studied for multiple industrial applications and are popular due to their biocompatibility. Insulin degludec, an analogue of human insulin, exists as di-hexamer in pharmaceutical formulations and has the potential to form long multi-hexamers in physiological environment, which dissociate into monomers to bind with receptors on the cell membrane. This study involved complexation of two negatively charged bio-polymers xanthan and alginate with clinically-relevant insulin degludec (PIC). The polymeric complexations and interactions were investigated using biophysical methods. Intrinsic viscosity [η] and particle size distribution (PSD) of PIC increased significantly with an increase in temperature, contrary to the individual components indicating possible interactions. [η] trend was X > XA > PIC > A > IDeg. PSD trend was X > A > IDeg > XA > PIC. Zeta (ζ)- potential (with general trend of IDeg < A < XA < X ≈ PIC) revealed stable interaction at lower temperature which gradually changed with an increase in temperature. Likewise, sedimentation velocity indicated stable complexation at lower temperature. With an increase in time and temperature, changes in the number of peaks and area under curve were observed for PIC. Conclusively, stable complexation occurred among the three polymers at 4 °C and 18 °C and the complex dissociated at 37 °C. Therefore, the complex has the potential to be used as a drug delivery vehicle.

Abstract
IN BRIEF The use of long-acting basal insulin analogs is a recommended strategy in older people with diabetes because of their lower risk of hypoglycemia compared to intermediate-acting insulins. In this article, we review the results from recent clinical trials of second-generation basal insulin preparations. We conclude that, although these preparations have improved the management of insulin-requiring older people with type 2 diabetes, there is a need for additional and more specific studies to address the complexities of hyperglycemia management in this population.

Abstract
INTRODUCTION Hypoglycemia resulting from insulin therapy for treatment of diabetes increases the risk of adverse cardiovascular events. Determining biomarkers that provide accurate estimation of hypoglycemia risk may allow for more accurate patient management and care. The purpose of this study was to determine the cutoff value of serum albumin (s-alb) that increases the risk of hypoglycemia in patients treated with insulin degludec. METHODS This study used a crossover design and randomized 30 patients admitted for glycemic control to compare differences between insulin glargine 300 U/ml (Gla300) and degludec treatments. RESULTS The cutoff value of s-alb associated with 24-h hypoglycemia and nocturnal hypoglycemia in patients treated with degludec was 3.8 g/dl. In patients with s-alb levels < 3.8 g/dl, mean percentages of time with hypoglycemia, clinically important hypoglycemia, and nocturnal hypoglycemia were significantly lower in those treated with Gla300 compared with patients treated with degludec. CONCLUSION This study identified a cutoff value for s-alb levels that indicates risk of hypoglycemia in patients treated with degludec. Monitoring s-alb levels in patients treated with degludec will help to mitigate the risk of hypoglycemia. TRIAL REGISTRATION University Hospital Medical Information Network (UMIN 000031044).

Abstract
OBJECTIVE Many youth with diabetes struggle to meet glycemic targets. The new ultralong duration of action of insulin degludec (iDeg) holds potential to ameliorate missed doses of basal insulin and improve glycemic control in youth with diabetes. METHODS A retrospective chart review was undertaken of youth age 13 to <24 years in our practice with type 1 diabetes (T1D) or type 2 diabetes (T2D) who had been switched from glargine or detemir to iDeg to evaluate the impact of this transition on glycemic control. RESULTS Glycated hemoglobin A1c (HbA1c) in youth with T1D (n = 82) remained stable during 6 months of treatment with iDeg (10.1 ± 2.11% [87 ± 23 mmol/mol] at start of iDeg compared to 10.1 ± 2.12% [87 ± 23 mmol/mol] at 6 months of treatment), whereas in youth with T2D (n = 16), HbA1c significantly declined from 10.6 ± 2.3% (92 ± 25 mmol/mol) to 8.3 ± 2.2% (67 ± 24 mmol/mol) ( P = .0024). CONCLUSION In youth switched to iDeg, which in our practice is commonly due to ineffectiveness of the patient's current regimen, the outcome differences we saw may be due to preserved beta-cell function in youth with T2D. It remains to be seen whether there are benefits of transition to iDeg in youth with T1D beyond glycemic outcomes, such as reduction in ketosis and episodes of diabetic ketoacidosis. ABBREVIATIONS DKA = diabetic ketoacidosis; DPV = Diabetes-Patienten-Verlaufsdokumentation (German/Austrian Prospective Diabetes Follow-Up Registry); HbA1c = glycated hemoglobin A1c; iDeg = insulin degludec; T1D = type 1 diabetes; T2D = type 2 diabetes.

Abstract
Traditional approaches to achieve sustained delivery of pharmaceutical peptides traditionally use co-excipients (e.g., microspheres and hydrogels). Here, we investigate the release of an amyloidogenic glucagon analogue (3474) from an aggregated state and the influence of surfactants on this process. The formulation of peptide 3474 in dodecyl maltoside (DDM), rhamnolipid (RL), and sophorolipid (SL) led to faster fibrillation. When the aggregates were subjected to multiple cycles of release by repeated resuspension in fresh buffer, the kinetics of the release of soluble peptide 3474 from different surfactant aggregates all followed a simple exponential decay fit, with half-lives of 5–18 min and relatively constant levels of release in each cycle. However, different amounts of peptide are released from different aggregates, ranging from 0.015 mg/mL (3475-buffer) up to 0.03 mg/mL (3474-DDM), with 3474-buffer and 3474-RL in between. In addition to higher release levels, 3474-DDM aggregates showed a different amyloid FTIR structure, compared to 3474-RL and 3474-SL aggregates and a faster rate of degradation by proteinase K. This demonstrates that the stability of organized peptide aggregates can be modulated to achieve differences in release of soluble peptides, thus coupling aggregate polymorphism to differential release profiles. We achieved aggregate polymorphism by the addition of different surfactants, but polymorphism may also be reached through other approaches, including different excipients as well as changes in pH and salinity, providing a versatile handle to control release profiles.

Abstract
AIMS/INTRODUCTION Compared with glargine 100 U/mL (Gla100), glargine 300 U/mL (Gla300) and degludec (Deg) - the ultralong-acting insulins - reportedly have more stable effects and reduce the risk of hypoglycemia. Currently, they are considered to be the most useful basal insulins. The present study aimed to compare the efficacy and safety of Gla300 and Deg on glycemic control using continuous glucose monitoring. MATERIALS AND METHODS In this single-center, open-label, parallel-group, two-period, cross-over study, 30 patients with type 2 diabetes were randomized to once-daily Gla300 followed by Deg with the same units (n = 15) or vice versa (n = 15). The primary end-points of this study were the mean percentage of time within the target glucose range of 70-180 mg/dL as efficacy and hypoglycemia of <70 mg/dL as safety indicators, as measured using continuous glucose monitoring during each treatment period. RESULTS The mean percentage of time within the target glucose range was not different between Gla300 and Deg (77.8 ± 19.2 vs 76.9 ± 18.3%, P = 0.848). However, the mean percentage of time of hypoglycemia with Gla300 was significantly lower than that of Deg (1.3 ± 2.7 vs 5.5 ± 6.4%, P = 0.002). In the secondary safety end-points, the mean percentage of time of severe hypoglycemia (<54 mg/dL) or nocturnal hypoglycemia with Gla300 was also significantly lower than that of Deg. CONCLUSIONS The present study showed the comparable efficacy of Gla300 and Deg on glycemic control; however, the risk of hypoglycemia was markedly lower for Gla300 than for Deg.

AIMS To compare the time spent in specified glycaemic ranges in people with type 1 diabetes (T1D) during 5 consecutive days of moderate-intensity exercise while on either 100% or 75% of their usual insulin degludec (IDeg) dose. MATERIALS AND METHODS Nine participants with T1D (four women, mean age 32.1 ± 9.0 years, body mass index 25.5 ± 3.8 kg/m2 , glycated haemoglobin 55 ± 7 mmol/mol (7.2% ± 0.6%) on IDeg were enrolled in the trial. Three days before the first exercise period, participants were randomized to either 100% or 75% of their usual IDeg dose. Participants exercised on a cycle ergometer for 55 minutes at a moderate intensity for 5 consecutive days. After a 4-week wash-out period, participants performed the last exercise period for 5 consecutive days with the alternate IDeg dose. Time spent in specified glycaemic ranges, area under the curve and numbers of hypoglycaemic events were compared for the 5 days on each treatment allocation using a paired Students' t test, Wilcoxon matched-pairs signed-rank test and two-way ANOVA. RESULTS Time spent in euglycaemia over 5 days was greater for the 75% IDeg dose versus the 100% IDeg dose (4008 ± 938 minutes vs. 3566 ± 856 minutes; P = 0.04). Numbers of hypoglycaemic events (P = 0.91) and time spent in hypoglycaemia (P = 0.07) or hyperglycaemia (P = 0.38) was similar for both dosing schemes. CONCLUSIONS A 25% reduction in usual IDeg dose around regular exercise led to more time spent in euglycaemia, with small effects on time spent in hypo- and hyperglycaemia.

Abstract
BACKGROUND AND PURPOSE In the past decade, there has been much advancement in oral antidiabetic agents, but few changes in insulin therapy. With the addition of the ultra-long-acting insulins, insulin glargine U300 (IGlar 300) and insulin degludec (IDeg 100 and IDeg 200), it is important to understand key aspects in the agents' clinical properties, efficacy, safety, dosing, packaging, and place in therapy. METHODS A literature review was conducted using PubMed database and was limited to English, full-text articles published from January 2000 to January 2018. The following search terms were used: insulin glargine 300, insulin degludec, Toujeo, Tresiba, and ultra-long-acting insulin. CONCLUSIONS These agents are longer acting with sustained insulin coverage as compared with other basal insulins while having a low potential for hypoglycemia. Efficacy and safety profiles are quite good, and potential for weight gain was similar to IGlar 100. IMPLICATIONS FOR PRACTICE Depending on the patient's needs, these newer agents may offer some advantages. Insulin glargine U300 and IDeg 200 are concentrated, allowing for administration of large doses by less volume, thereby theoretically improving absorption. For patients needing flexible dosing, IDeg may be beneficial. The ultra-long-acting agents may also be useful if it is suspected that the basal insulin is not lasting the entire day.

Abstract
OBJECTIVE To compile, analyze, and summarize the literature on concentrated insulins (i.e. concentrations >100 units/mL) from randomized controlled trials and derive guidance on appropriate use of these agents. METHODS Searches were conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, Trialtrove (through April 2016) and ClinicalTrials.gov (through April 2017) for phase 1-4 clinical studies using concentrated insulins. Selected studies included multiple-arm, randomized controlled trials evaluating subcutaneously administered concentrated insulins. Trial registration numbers (selected studies) were searched in Medline, Embase and Google Scholar (through April 2017). Late-phase studies were graded using guidance from the Agency for Healthcare Research and Quality. RESULTS Thirty-eight completed trials (7900 participants) and 34 qualifying publications were identified. Four marketed concentrated insulins were evaluated: two long-acting basal (insulin glargine 300 units/mL and insulin degludec 200 units/mL [IDeg200]), one rapid-acting prandial (insulin lispro 200 units/mL [ILis200]), and one prandial/basal (human regular insulin 500 units/mL). Early-phase trials established bioequivalence for IDeg200 and ILis200 with the corresponding 100 units/mL formulations. Efficacy studies showed noninferior glycemic control between comparators for long-acting basal and prandial/basal products with generally low severe hypoglycemia. Six additional concentrated insulins with completed early-phase development were also identified. CONCLUSION Concentrated-insulin products demonstrated efficacious and safe outcomes in appropriate patients. Clinical findings (HbA1c and hypoglycemia) and methodology (initiation and titration), patient factors (insulin experience and dosing requirements) and treatment characteristics (bioequivalence, potency and device features) are important considerations. This overview of these and other factors provides essential information and guidance for using concentrated insulins in clinical practice.

Abstract
INTRODUCTION Hyperglycemia in inpatients is a major problem, especially when nutritional support is required. This study aims to assess the impact of treatment with insulin degludec (IDeg) on mean blood glucose (BG) and glycemic variability in noncritical hospitalized patients with and without type 2 diabetes (T2DM) receiving enteral and/or parenteral nutrition (EN, PN). METHODS Mean BG and glycemic variability from admission up to 7 days of hospitalization were evaluated in consecutive cases with and without T2DM. Percentage of coefficient of variation (CV) for glucose was used to express glycemic variability. RESULTS Overall, 26 patients (13 with and 13 without T2DM) were admitted to the hospital for any cause. Subjects were 65.4% men and they were mainly elderly (mean age 66.3 ± 13.4 years). PN was administered in 88.5% of patients and EN in 19.2%. At admission, mean HbA1c level was 5.9 ± 0.7% in patients without diabetes and 9.1 ± 2.5% in patients with T2DM. During hospitalization, mean daily BG levels changed from 151 ± 47.3 mg/dl (day 1) to 157 ± 66.7 mg/dl (day 7) in patients without diabetes and from 210 ± 66.5 mg/dl to 192 ± 48.6 mg/dl in patients with T2DM. CV decreased from 14% (day 1) to 11% (day 7) in patients without diabetes and from 20% (day 1) to 9% (day 7) in patients with T2DM. No symptomatic or severe hypoglycemia occurred. CONCLUSIONS Despite the small sample size and the lack of control group, this study represents the first proof-of-concept that IDeg in hospitalized patients with or without T2DM who require nutritional support has the potential to maintain stable levels of BG and reduce glycemic variability.

Abstract
Insulin analogues play a key role in the effective management of type 2 diabetes. However, there are several behavioural barriers to appropriate early initiation of insulin therapy, despite compelling evidence supporting the benefits of this strategy in those patients for whom oral anti-diabetes agents provide insufficient control. The development of second-generation insulin analogues (insulin glargine 300 U/mL and insulin degludec) has provided physicians with agents that can provide comparable glycaemic control to first-generation insulin, but with a reduced risk of hypoglycaemia and modes of action suited to once-daily regimens. These characteristics may help overcome patient and physician concerns about early insulin use in disease management. To date, there have been no head-to-head comparisons of second-generation insulins: here we consider recent real-world evidence and the forthcoming direct comparison in the BRIGHT randomised controlled study, as presented at the recent 11th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD) 2018.

Abstract
AIMS To determine the safety and efficacy of insulin degludec versus glargine in patients with type 1 (T1D) and type 2 (T2D) diabetes mellitus. METHODS Databases were searched until July 5, 2017. We included randomized controlled trials comparing degludec with glargine in diabetic patients, each with a minimum of 16 weeks of follow-up. RESULTS Eighteen trials with 16,791 patients were included. Degludec was associated with a statistically significant reduction in risk for all confirmed hypoglycemia at the maintenance treatment period [estimated rate ratio (ERR) 0.81; 95% confidence interval (CI) 0.72‒0.92; P = 0.001], nocturnal confirmed hypoglycemia at the entire (ERR 0.71; 95% CI 0.63‒0.80; P < 0.001) and maintenance treatment period (ERR 0.65; 95% CI 0.59‒0.71; P < 0.001), all irrespective of the pooled diabetic populations and follow-up durations. The differences in the rate of hypoglycemia were more pronounced in nocturnal period and maintenance period and in T2D than T1D patients. Degludec reduced the incidence of severe hypoglycemia in T2D [ERR 0.65; (0.52; 0.89); P = 0.005] but not T1D patients. HbA1c concentration was slightly higher in degludec over glargine but was not clinically relevant [estimated treatment difference (ETD) 0.03; 95% CI - 0.00 to 0.06%; P = 0.06]. Fasting plasma glucose level was lower in degludec-treated patients (ETD - 0.28 mmol/L; 95% CI - 0.44 to - 0.11 mmol/L; P = 0.001). Several subgroup analyses showed largely consistent findings. The rates of adverse events including total mortality and cardiovascular events were not significantly different between two treatment strategies. CONCLUSIONS Insulin degludec appears to have better safety in reducing hypoglycemic events with similar efficacy compared with insulin glargine.

Abstract
IN BRIEF Titratable fixed-ratio combinations (FRCs) of a basal insulin and a glucagon-like peptide-1 (GLP-1) receptor agonist are new therapeutic options for people with type 2 diabetes. Two FRCs-insulin degludec/liraglutide and insulin glargine/lixisenatide-have been approved for use in the United States. The two components in these FRCs target different aspects of diabetes pathophysiology, working in a complementary manner to decrease blood glucose while mitigating the side effects associated with each component (hypoglycemia and weight gain with insulin and gastrointestinal side effects with GLP-1 receptor agonists). This article reviews these products and key considerations for their use.

Abstract
BACKGROUND We wanted to determine whether basal insulin requirements change when patients transition from insulin glargine U-100 (Gla-100) to insulin glargine U-300 (Gla-300) or insulin degludec. METHODS This study involved subjects seen in the University of Colorado Health Endocrine Clinic who were transitioned from Gla-100 to either Gla-300 (n = 95) or insulin degludec (n = 39). The primary outcome was the difference between baseline Gla-100 dose and dose of Gla-300 or insulin degludec prescribed after first follow-up visit within 1-12 months. Secondary outcomes included changes in glycemic control and empiric dose conversion from Gla-100 to Gla-300 or insulin degludec on the day of transition. Wilcoxon rank sum tests evaluated changes in insulin doses, and paired t tests assessed changes in glycemic control using GraphPad statistical software. RESULTS Median daily basal insulin dose increased for individuals transitioned from Gla-100 to Gla-300 from 30 [19-60 interquartile range (IQR)] units at baseline to 34.5 (19-70 IQR) units after follow up (p = 0.01). For patients transitioned to insulin degludec, dose changes from baseline to follow up were not significantly different (p = 0.56). At the time of transition, the prescribed dose of Gla-300 or insulin degludec did not significantly differ from the previous dose of Gla-100 (p = 0.73 and 0.28, respectively), indicating that empiric dose adjustments were not routinely prescribed. CONCLUSIONS Patients who transitioned from Gla-100 to Gla-300 had increased basal insulin requirements between visits, while basal insulin requirements for those transitioned from Gla-100 to insulin degludec were not significantly different.

Abstract
Basal insulin remains the mainstay of treatment of type 2 diabetes when diet changes and exercise in combination with oral drugs and other injectable agents are not sufficient to control hyperglycemia. Insulin therapy should be individualized, and several factors influence the choice of basal insulin; these include pharmacological properties, patient preferences, and lifestyle, as well as health insurance plan formularies. The recent availability of basal insulin formulations with longer durations of action has provided further dosing flexibility; however, patients may need to switch agents throughout therapy for a variety of personal, clinical, or economic reasons. Although a unit-to-unit switching approach is usually recommended, this conversion strategy may not be appropriate for all patients and types of insulin. Glycemic control and risk of hypoglycemia must be closely monitored by health care providers during the switching process. In addition, individual changes in care and formulary coverage need to be adequately addressed in order to enable a smooth transition with optimal outcomes.

Abstract
Insulin therapy (IT) is initiated for patients with type 2 diabetes mellitus when glycaemic targets are not met with diet and other hypoglycaemic agents. The initiation of IT improves glycaemic control and reduces the risk of microvascular complications. There is, however, an associated weight gain following IT, which may adversely affect diabetic and cardiovascular morbidity and mortality. A 3 to 9 kg insulin-associated weight gain (IAWG) is reported to occur in the first year of initiating IT, predominantly caused by adipose tissue. The potential causes for this weight gain include an increase in energy intake linked to a fear of hypoglycaemia, a reduction in glycosuria, catch-up weight, and central effects on weight and appetite regulation. Patients with type 2 diabetes who are receiving IT often have multiple co-morbidities, including obesity, that are exacerbated by weight gain, making the management of their diabetes and obesity challenging. There are several treatment strategies for patients with type 2 diabetes, who require IT, that attenuate weight gain, help improve glycaemic control, and help promote body weight homeostasis. This review addresses the effects of insulin initiation and intensification on IAWG, and explores its potential underlying mechanisms, the predictors for this weight gain, and the available treatment options for managing and limiting weight gain.

Abstract
BACKGROUND The long-acting insulin analogue degludec is a therapeutic option for patients with type 1 (T1D) or type 2 diabetes (T2D). Aim of this analysis was to investigate differences in clinical characteristics of patients before and after initiating degludec use in a cohort of German/Austrian patients. METHODS 1064 subjects with T1D/T2D and documented degludec use from the Diabetes-Patient-Follow-Up (DPV) registry were included. The follow-up cohort (n=421) comprised patients with available data before and 3-15months after switching to degludec. A t-test for paired values was implemented to compare rates of severe hypoglycaemia, and mean values for HbA1C, BMI, basal insulin dose/kg bodyweight/day, and the number of basal insulin injections/day before and after switching to degludec Results were stratified by type of diabetes. In T1D, subgroup analyses were conducted (age, sex, basal insulin used before switching). P<0.05 was considered significant. FINDINGS In T1D (n=360), basal insulin dose (0.43±0.17 to 0.38±0.13IU) and the number of basal injections/day (1.7±0.6 to 1.1±0.3) decreased whereas BMI increased from 23.2±4.8 to 24.0±5.0kg/m2 (all p<0.0001) after switching to degludec. No significant changes were observed regarding rates of severe hypoglycaemia or HbA1C-values. Findings were comparable for subgroups. In T2D (n=61), basal insulin dose (0.41±0.23 to 0.38±0.21; p=0.1730) and the number of basal injections/day (1.3±0.4 to 1.1±0.3; p=0.0097) decreased after switching to degludec. HbA1C improved from 7.9±1.6 to 7.1±1.5% (p<0.0001). CONCLUSIONS The DPV registry provides data from real-life diabetes care. Our analysis predominantly confirmed results from clinical trials and provides additional information complementing the clinical study program of degludec.

Abstract
AIMS/HYPOTHESIS To determine the association between inpatient glycemic variability and long-term mortality in patients with type 2 diabetes mellitus. METHODS Capillary blood glucose (CBG) of inpatients from 8 hospitals was analysed. 28,353 admissions identified were matched for age, duration of diabetes and admission and median and interquartile range of CBG. 6year mortality was investigated for (i) those with CBG IQR in the top half of all IQR measurements (matched for all except IQR), vs those in the lower half and (ii) those with the lowest quartile median glucose (matched for all except median). RESULTS CONCLUSION: Higher inpatient glycemic variability is associated with increased mortality on long-term follow up. When matched by IQR, we have demonstrated higher median CBG is associated with lower long-term mortality. CBG variability may increase cardiovascular morbidity by increasing exposure to hypoglycaemia or to variability per se. In hospitalized patients with diabetes, glycemic variability should be minimised and when greater CBG variability is unavoidable, a less stringent CBG target considered.

Abstract
Newer insulin products have advanced the evolution of insulin replacement options to more accurately mimic natural insulin action. There are new, modified, and concentrated insulins; administration devices calibrated for both increased concentrations and administration accuracy to improve adherence and safety; and inhaled insulin. There are new combinations of longer-acting basal insulin and rapid-acting insulin or glucagon like protein-1 receptor agonists. Existing insulin replacement designs and methods can be updated using these tools to improve efficacy and safety. Individualized decisions to use them should be based on patient physiologic needs, self-care ability, comorbidities, and cost considerations.

Abstract
DEVOTE was designed to evaluate the cardiovascular safety of insulin degludec (IDeg) vs insulin glargine U100 (IGlar) in patients with T2D at high risk of cardiovascular events. DEVOTE is a phase 3b, multicenter, international, randomized, double-blind, active comparator-controlled trial, designed as an event-driven trial that would continue until 633 positively adjudicated primary events were accrued. The primary end point was the time from randomization to a composite outcome consisting of the first occurrence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Patients with T2D at high risk of cardiovascular complications were randomized 1:1 to receive either IDeg or IGlar, each added to background therapies. This trial was designed to demonstrate statistical noninferiority of IDeg vs IGlar for the primary end point. DEVOTE enrolled 7,637 patients between October 2013 and November 2014 at 436 sites in 20 countries. Of these, 6,506 patients had prior cardiovascular disease or chronic kidney disease, and the remainder had multiple cardiovascular risk factors. DEVOTE was designed to provide conclusive evidence regarding the cardiovascular safety of IDeg relative to IGlar in a high-risk population of patients with T2D.

Abstract
Type 2 diabetes (T2DM) is a common condition. Treatment of diabetes and related complications can be complex. In addition to lifestyle changes, medications play an important role in controlling patients' blood glucose levels and preventing complications. From an individual and societal standpoint, it is also an expensive disease. Medical spending attributed to diabetes per individual is significant. With appropriate therapy, patients can lead full, healthy lives with the disease, so making informed decisions regarding pharmacotherapy for T2DM is clearly of great importance.

Abstract
The global burden of type 2 diabetes is estimated to currently affect over 350 million people worldwide and is anticipated to continue increasing over the next 20 years. Current treatment guidelines recommend the choice of pharmacotherapy based upon patient-specific parameters, with combination therapy for patients with a hemoglobin A1c level ≥9%. A new combination therapy of insulin degludec + liraglutide provides a long-acting basal insulin with a glucagon-like peptide agonist. In clinical trials, this combination product has reduced hemoglobin A1c and fasting plasma glucose more than the individual agents alone. Further advantages observed with this combination include weight loss and decrease in hypoglycemia compared to basal insulin alone.

Abstract
There is ongoing interest in optimizing basal insulin treatment by developing insulins with a flat pharmacological profile, a long duration of action (typically beyond 24 hours) and minimum day-to-day variation. Glargine-300 is a modified form of the long-acting insulin analog glargine in that it has been concentrated at 300 units/mL rather than the conventional 100 units/mL. Glargine-300 has a longer duration of action and a flatter pharmacological profile than original glargine-100. This property allows for more flexibility around the timing of administration, when injected once per day. Open-label studies in patients with diabetes have shown that treatment with glargine-300 achieves comparable glycemic control compared to treatment with glargine-100, albeit with consistently higher insulin requirements. These studies also showed that treatment with glargine-300 was associated with lower risks of nocturnal hypoglycemia in patients with type 2 diabetes, particularly those already on insulin, whereas data are mixed in insulin-naïve patients with type 2 diabetes or in patients with type 1 diabetes. Treatment with glargine-300 did not appear to affect the risk of overall hypoglycemia, whereas studies lacked sufficient power to investigate the effect on the risk of severe hypoglycemia. Future studies need to establish the role of glargine-300 in the treatment of diabetes alongside the other new long-acting insulin analog, insulin degludec, which was recently introduced to the market.

Abstract
Chronic hyperglycemia is the primary risk factor for the development of complications in diabetes mellitus (DM); however, it is believed that frequent or large glucose fluctuations may independently contribute to diabetes-related complications. Postprandial spikes in blood glucose, as well as hypoglycemic events, are blamed for increased cardiovascular events in DM. Glycemic variability (GV) includes both of these events; hence, minimizing GV can prevent future cardiovascular events. Correcting GV emerges as a target to be pursued in clinical practice to safely reduce the mean blood glucose and to determine its direct effects on vascular complications in diabetes. Modern diabetes management modalities, including glucagon-related peptide-1-based therapy, newer insulins, modern insulin pumps and bariatric surgery, significantly reduce GV. However, defining GV remains a challenge primarily due to the difficulty of measuring it and the lack of consensus regarding the optimal approach for its management. The purpose of this manuscript was not only to review the most recent evidence on GV but also to help readers better understand the available measurement options and how the various definitions relate differently to the development of diabetic complications.
