Abstract
AIMS: To compare the cardiovascular, renal and safety outcomes of second-line glucose-lowering agents used in the management of people with type 2 diabetes. METHODS MEDLINE, EMBASE and CENTRAL were searched from inception to 13 July 2021 for randomised controlled trials comparing second-line glucose lowering therapies with placebo, standard care or one another. Primary outcomes included cardiovascular and renal outcomes. Secondary outcomes were non-cardiovascular adverse events. Risk ratios (RRs) and corresponding confidence intervals (CI) or credible intervals (CrI) were reported within pairwise and network meta-analysis. The quality of evidence was evaluated using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) criteria. Number needed to treat (NNT) and number needed (NNH) to harm were calculated at 5 years using incidence rates and RRs. PROSPERO (CRD42020168322). RESULTS We included 38 trials from seven classes of glucose-lowering therapies. Both sodium-glucose co-transporter-2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP1RA) showed moderate to high certainty in reducing risk of 3-point major adverse cardiovascular events, 3P-MACE (network estimates: SGLT2i [RR 0.90; 95% CrI 0.84-0.96; NNT, 59], GLP1RA [RR 0.88; 95% CrI 0.83-0.93; NNT, 50]), cardiovascular death, all-cause mortality, renal composite outcome and macroalbuminuria. SGLT2i also showed high certainty in reducing risk of hospitalization for heart failure (hHF), ESRD, acute kidney injury, doubling in serum creatinine and decline in eGFR. GLP1RA were associated with lower risk of stroke (high certainty) while glitazone use was associated with an increased risk of hHF (very low certainty). The risk of developing ESRD was lower with the use of sulphonylureas (low certainty). For adverse events, sulphonylureas and insulin were associated with increased hypoglycaemic events (very low to low certainty), while GLP1RA increased the risk of gastrointestinal side effects leading to treatment discontinuation (low certainty). DPP-4i increased risk of acute pancreatitis (low certainty). SGLT2i were associated with increased risk of genital infection, volume depletion (high certainty), amputation and ketoacidosis (moderate certainty). Risk of fracture was increased with the use of glitazones (moderate certainty). CONCLUSIONS SGLT2i and GLP1RA were associated with lower risk for different cardiorenal end points, when used as an adjunct to metformin in people with type 2 diabetes. Additionally, SGLT2i demonstrated benefits in reducing risk for surrogate end points in kidney disease progression. Safety outcomes differ among the available pharmacotherapies.

Diabetes & metabolic syndrome. 2021;(3):901-907
Abstract
BACKGROUND Policaptil Gel Retard® (PGR), is a new macromolecule complex based on polysaccharides slowing the rate of carbohydrate and fat absorption. It proved to significantly reduce body weight, acanthosis nigricans expression, HbA1c levels, and glucose metabolism abnormalities in obese, hyper-insulinemic adolescents. No such data are available for adults. AIM: to compare the effects of PGR vs. metformin in adult subjects with the Metabolic Syndrome (MS) and T2DM on a Low Glycemic Index diet. SUBJECTS AND METHODS This spontaneous clinical, longitudinal, single-blind, randomized study based on a per-protocol analysis enrolled 100 outpatients with MS and T2DM consecutively referring to our clinic for three months, and randomly assigned to either the active treatment (Group A:, 6 tablets/day) or the comparator (Group B: Metformin tablets, 1500-2000 mg/day in two divided doses during the two main meals, to minimize side effects) to be taken 30 min before each main meal in equally divided doses. Serum lipid profile, anthropometry, HOMA-IR index, and tolerability parameters were evaluated before and after a 6-month follow-up period. RESULTS all parameters improved at a similar rate in both groups but for the lipid profile, which got even better in Group A. Group A also experienced less prominent gastrointestinal side effects than its counterpart. CONCLUSION For the first time, we showed the non-inferiority of PGR compared to metformin in obese adult subjects with the MS and T2DM as for glycemic control and a clear-cut superiority of PGR in terms of both serum lipid-lowering capacity and tolerability.

Abstract
AIMS/INTRODUCTION To identify the effect of combination therapy with a dipeptidyl peptidase-4 inhibitor and a sodium-glucose cotransporter 2 inhibitor compared with switching from a dipeptidyl peptidase-4 inhibitor to a sodium-glucose cotransporter 2 inhibitor on improving the glucose variability in patients with or without impaired endogenous insulin secretion. MATERIALS AND METHODS A secondary analysis regarding the relationship between endogenous insulin secretion and the change in mean amplitude of glycemic excursions (ΔMAGE) was carried out in a multicenter, prospective, randomized, parallel-group comparison trial that enrolled patients with type 2 diabetes who had been taking teneligliptin and were treated by switching to canagliflozin (SWITCH) or adding canagliflozin (COMB). Participants were categorized into the following four subgroups: SWITCH or COMB and high or low fasting C-peptide (CPR) divided at baseline by the median. RESULTS ΔMAGE in the COMB group was greatly improved independent of a high or low CPR (-29.2 ± 28.3 vs -20.0 ± 24.6, respectively; P = 0.60). However, ΔMAGE was not ameliorated in the low CPR SWITCH group, and the ΔMAGE was significantly smaller than that in the high CPR COMB group (P < 0.01). CONCLUSIONS COMB would be a better protocol rather than switching teneligliptin to canagliflozin to improve daily glucose variability in patients with impaired endogenous insulin secretion.

Current medical research and opinion. 2020;(7):1117-1124
Abstract
Objective: Observational evidence suggests that patients with type 2 diabetes mellitus (T2DM) are at increased risk for acute pancreatitis (AP) versus those without T2DM. A small number of AP events were reported in clinical trials of the sodium glucose co-transporter 2 inhibitor canagliflozin, though no imbalances were observed between treatment groups. This observational study evaluated risk of AP among new users of canagliflozin compared with new users of six classes of other antihyperglycemic agents (AHAs).Methods: Three US claims databases were analyzed based on a prespecified protocol approved by the European Medicines Agency. Propensity score adjustment controlled for imbalances in baseline covariates. Cox regression models estimated the hazard ratio of AP with canagliflozin compared with other AHAs using on-treatment (primary) and intent-to-treat approaches. Sensitivity analyses assessed robustness of findings.Results: Across the three databases, there were between 12,023-80,986 new users of canagliflozin; the unadjusted incidence rates of AP (per 1000 person-years) were between 1.5-2.2 for canagliflozin and 1.1-6.6 for other AHAs. The risk of AP was generally similar for new users of canagliflozin compared with new users of glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, sulfonylureas, thiazolidinediones, insulin, and other AHAs, with no consistent between-treatment differences observed across databases. Intent-to-treat and sensitivity analysis findings were qualitatively consistent with on-treatment findings.Conclusions: In this large observational study, incidence rates of AP in patients with T2DM treated with canagliflozin or other AHAs were generally similar, with no evidence suggesting that canagliflozin is associated with increased risk of AP compared with other AHAs.

Journal of the American College of Cardiology. 2020;(5):512-521
Abstract
BACKGROUND Whereas there exists a direct relationship between glycated hemoglobin and cardiovascular disease (CVD), clinical trials targeting glycated hemoglobin to near-normal levels using intensive therapy have failed to prevent CVD and have even increased mortality, making clinical decision making difficult. A common polymorphism at the haptoglobin (Hp) genetic locus is associated with CVD, especially coronary heart disease, in the setting of hyperglycemia. OBJECTIVES This study sought to determine whether the treatment difference of intensive versus standard glucose-lowering therapy on risk of CVD events in the ACCORD (Action to Control Cardiovascular Risk in Diabetes) study depended on Hp phenotype. METHODS Hp phenotype was measured within 5,806 non-Hispanic white ACCORD participants using a validated assay. Adjusted hazard ratios (aHR) with 95% confidence intervals (CI) estimated from stratified Cox regression models were used to quantify the association between intensive therapy and incident CVD for the 2 different Hp phenotype groups (Hp2-2, Hp1 carriers). RESULTS Compared with standard therapy, intensive therapy was associated with a lower risk of incident coronary heart disease among participants with the Hp2-2 phenotype (n = 2,133; aHR: 0.71; 95% CI: 0.55 to 0.91; p = 0.006), but not among the other 2 phenotypes (Hp1 allele carriers) (n = 3,673; aHR: 0.95; 95% CI: 0.79 to 1.13; p = 0.550). The same pattern was observed for CVD. Conversely, intensive therapy was associated with an increased risk of fatal CVD (aHR: 1.50; 95% CI: 1.00 to 2.25; p = 0.049) and total mortality (aHR: 1.40; 95% CI: 1.08 to 1.81; p = 0.011) among the Hp1 carriers, whereas this risk was not increased in the Hp2-2 phenotype (fatal CVD: aHR: 1.02; 95% CI: 0.59 to 1.77; p = 0.931; total mortality: aHR: 0.98; 95% CI: 0.68 to 1.41; p = 0.908). CONCLUSIONS Intensive glucose-lowering therapy was effective at preventing incident coronary heart disease and CVD events in ACCORD study participants with the Hp2-2 phenotype but not in Hp1 carriers, who had increased mortality risk from intensive therapy.

Abstract
INTRODUCTION Randomized controlled trials and real-world data from the USA have shown similar glycemic control with insulin glargine 300 U/ml (Gla-300) and insulin glargine 100 U/ml (Gla-100) and reduced hypoglycemia risk with Gla-300. This real-world study describes the efficacy and safety of Gla-300 and Gla-100 in patients with type 2 diabetes (T2D) in France, Spain, and Germany. METHODS This retrospective chart review analysis used anonymized data for adults with T2D switching basal insulin analog (BIA) therapy to Gla-300 or Gla-100, or insulin-naïve patients initiating Gla-300 or Gla-100. Outcomes included change from baseline to 6-month follow-up in glycated hemoglobin A1c (A1C), total and severe hypoglycemia incidences and events, insulin dose, and reasons for BIA choice. RESULTS Six hundred sixty-five physicians (33.8% Spain, 31.7% France, 34.4% Germany) provided chart data for patients switching to Gla-300 (n = 679) or Gla-100 (n = 429) or initiating Gla-300 (n = 719) or Gla-100 (n = 711). After adjustment for baseline characteristics, A1C reductions from baseline were similar for patients switching to Gla-300 or Gla-100 (- 0.87% vs. - 0.93%; p = 0.326) while those switched to Gla-300 vs. Gla-100 had a significantly greater mean reduction in hypoglycemic events (- 1.29 vs. - 0.81 events during 6 months; p = 0.012). Mean insulin doses after titration were 0.43 ± 0.36 and 0.40 ± 0.28 U/kg in Gla-300 and Gla-100 switchers, respectively. Factors that significantly influenced BIA choice included a lower risk of hypoglycemia (for Gla-300) and physician familiarity (for Gla-100). Outcomes for insulin-naïve patients were broadly similar to those of switchers. CONCLUSIONS In this real-world European study, patients with T2D who switched therapy to Gla-300 or Gla-100 had improved glycemic control and reduced hypoglycemia at 6 months, with significant hypoglycemia advantages with Gla-300.

Abstract
We aimed to determine whether sodium-glucose cotransporter type 2 inhibitors (SGLT2is) and incretin-based agents combination therapy produces more benefits than SGLT2is alone in patients with type 2 diabetes mellitus (T2DM). PubMed, Embase, and the Cochrane Library were searched for randomized controlled trials (RCTs) comparing SGLT2is plus Dipeptidyl-Peptidase 4 inhibitors (SGLT2is/DPP4is) or glucagon like peptide-1 receptor agonists (SGLT2is/GLP-1RAs) against SGLT2is as monotherapy or add-on to metformin in T2DMs. A total of 13 studies with 7350 participants were included. Combination with GLP-1RAs exhibited more HbA1c reduction (WMD: -0.8; 95% CI, -1.14 to -0.45%), weight loss (-1.46; 95% CI, -2.38 to -0.54 kg), and systolic blood pressure (SBP) reduction (-2.88; 95% CI, -4.52 to -1.25 mmHg) versus SGLT2is alone but increased the gastrointestinal disorder risk (RR: 1.68; 95% CI, 1.14-2.47). Combination with DPP4is exhibited an extra effect on HbA1c reduction (-0.47; 95% CI, -0.58 to -0.37%), a neutral effect on weight (0.19; 95% CI, -0.11 to 0.48 kg) and SBP (-0.01; 95% CI, -0.85 to 0.63 mmHg), and ameliorated the genital infections risk (0.73; 95% CI, 0.54-0.97) versus SGLT2is. Meta-regression indicated the hypoglycemic efficacy of SGLT2is/DPP4is is higher in Asians than in other ethnics, and the differences in BMI across ethnic groups may mediate this effect. SGLT2is and incretin-based agents combination therapy is efficacious and safe versus SGLT2is alone in T2DMs. Particularly, combination with GLP-1RAs shows additional benefits to glycemic, weight, and SBP control to a larger extent than DPP4is, while combination with DPP4is ameliorates the risk for genital infection seen with SGLT2is. We highlight the need for individualized treatment related to the selection of this novel combination therapy.

Advances in therapy. 2020;(9):3816-3826
Abstract
INTRODUCTION FPG GOAL was a 24-week, open-label, treat-to-target randomized controlled trial which demonstrated that the optimal self-monitored fasting blood glucose (SM-FBG) target for most Chinese individuals with type 2 diabetes (T2D) using insulin glargine 100 IU/mL was 3.9-6.1 mmol/L. Individuals who achieved lower fasting plasma glucose (FPG) levels might achieve the target HbA1c of < 7% without increasing the risk of hypoglycemia. METHODS For this post hoc analysis, individuals were redivided into three groups based on their actual laboratory FPG levels at 24 weeks: level 1, ≤ 5.6 mmol/L; level 2, > 5.6 to ≤ 6.1 mmol/L; and level 3, > 6.1 to ≤ 7.0 mmol/L. RESULTS At week 24, 863 individuals with diabetes had available FPG data and 179, 122, and 179 individuals achieved FPG levels 1, 2, and 3, respectively. The proportion of individuals with HbA1c < 7% or HbA1c < 7% without hypoglycemia (≤ 3.9 or ≤ 3.0 mmol/L) was significantly higher in FPG levels 1 (p < 0.01) and 2 (p < 0.05) than in level 3. The least squares mean changes from baseline in HbA1c (- 1.77% and - 1.66% vs - 1.34%; both p < 0.001) and 2-h postprandial glucose (- 3.88 mmol/L and - 3.98 mmol/L vs - 3.22 mmol/L; both p < 0.05) were also significantly higher in FPG levels 1 and 2 compared with level 3. Linear regression analysis showed a moderate relationship between FPG and HbA1c levels at 24 weeks (r = 0.449). CONCLUSIONS Chinese individuals with T2D who achieved lower FPG levels with insulin glargine 100 IU/mL were more likely to achieve the recommended target HbA1c of < 7% compared with those with higher FPG levels.

Abstract
AIMS/INTRODUCTION Non-alcoholic fatty liver disease (NAFLD) is often observed in individuals with type 2 diabetes mellitus, and it is known that the presence of type 2 diabetes mellitus leads to the aggravation of NAFLD. The aim of this study was to compare the possible effects of three kinds of oral hypoglycemic agents on NAFLD in individuals with type 2 diabetes mellitus. MATERIALS AND METHODS We carried out a prospective clinical trial (a randomized and open-label study) in patients with type 2 diabetes mellitus and NAFLD. A total of 98 patients were randomly allocated either to the dapagliflozin (n = 32), pioglitazone (n = 33) or glimepiride (n = 33) group, and the patients took these drugs for 28 weeks. The primary end-point was the change of the liver-to-spleen ratio on abdominal computed tomography. RESULTS There was no difference in baseline clinical characteristics among the three groups. Dapagliflozin, pioglitazone and glimepiride ameliorated hyperglycemia similarly. Bodyweight and visceral fat area were significantly decreased only in the dapagliflozin group. Serum adiponectin levels were markedly increased in the pioglitazone group compared with the other two groups. Dapagliflozin and pioglitazone, but not glimepiride, significantly increased the liver-to-spleen ratio, and the effects of dapagliflozin and pioglitazone on the liver-to-spleen ratio were comparable. CONCLUSIONS The present study showed that the decrease of visceral fat area and the increase of adiponectin level contributed to the improvement of NAFLD in patients with type 2 diabetes mellitus. Furthermore, dapagliflozin and pioglitazone exerted equivalent beneficial effects on NAFLD in patients with type 2 diabetes mellitus, although it seemed that these two drugs had different mechanisms of action.

Journal of the American Heart Association. 2020;(1):e012940
Abstract
Background Randomized controlled trials showed that newer glucose-lowering agents are cardioprotective, but most participants were men. It is unknown whether benefits are similar in women. Methods and Results Among adults with type 2 diabetes mellitus not controlled with metformin with no prior use of insulin, we assessed for sex differences in the cardiovascular effectiveness and safety of sodium-glucose-like transport-2 inhibitors (SGLT-2i), glucagon-like peptide-1 receptor agonists (GLP-1RA), dipeptidyl peptidase-4 inhibitors, initiated as second-line agents relative to sulfonylureas (reference-group). We studied type 2 diabetes mellitus American adults with newly dispensed sulfonylureas, SGLT-2i, GLP-1RA, or dipeptidyl peptidase-4 inhibitors (Marketscan-Database: 2011-2017). We used multivariable Cox proportional hazards models with time-varying exposure to compare time to first nonfatal cardiovascular event (myocardial infarction/unstable angina, stroke, and heart failure), and safety outcomes between drugs users, and tested for sex-drug interactions. Among 167 254 type 2 diabetes mellitus metformin users (46% women, median age 59 years, at low cardiovascular risk), during a median 4.5-year follow-up, cardiovascular events incidence was lower in women than men (14.7 versus 16.7 per 1000-person-year). Compared with sulfonylureas, hazard ratios (HRs) for cardiovascular events were lower with GLP-1RA (adjusted HR-women: 0.57, 95% CI: 0.48-0.68; aHR-men: 0.82, 0.71-0.95), dipeptidyl peptidase-4 inhibitors (aHR-women: 0.83, 0.77-0.89; aHR-men: 0.85, 0.79-0.91) and SGLT-2i (aHR-women: 0.58, 0.46-0.74; aHR-men: 0.69, 0.57-0.83). A sex-by-drug interaction was statistically significant only for GLP-1RA (P=0.002), suggesting greater cardiovascular effectiveness in women. Compared with sulfonylureas, risks of adverse events were similarly lower in both sexes for GLP-1RA (aHR-women: 0.81, 0.73-0.89; aHR-men: 0.80, 0.71-0.89), dipeptidyl peptidase-4 inhibitors (aHR-women: 0.82, 0.78-0.87; aHR-men: 0.83, 0.78-0.87) and SGLT-2i (aHR-women: 0.68, 0.59-0.78; aHR-men: 0.67, 0.59-0.78) (all sex-drug interactions for adverse events P>0.05). Conclusions Newer glucose-lowering drugs were associated with lower risk of cardiovascular events than sulfonylureas, with greater effectiveness of GLP-1RA in women than men. Overall, they appeared safe, with a better safety profile for SGLT-2i than for GLP-1RA regardless of sex.
