Background: MYL-1601D is a proposed biosimilar of originator insulin aspart, Novolog ® /NovoRapid ® (Ref-InsAsp-US/Ref-InsAsp-EU)., Objective: This study assessed the immunogenicity, efficacy, and safety of MYL-1601D with Ref-InsAsp-US in patients with type 1 diabetes mellitus (T1D)., Methods: This was a 24-week, open-label, randomized, phase III study. Patients were randomized 1:1 to mealtime MYL-1601D or Ref-InsAsp-US in combination with insulin glargine (Lantus SoloSTAR ® ) once daily. The treatment-emergent antibody response (TEAR) rate (defined as patients who were anti-insulin antibody [AIA] negative at baseline and became positive at any timepoint post-baseline or patients who were AIA positive at baseline and demonstrated a 4-fold increase in titer values at any timepoint post-baseline) was the primary endpoint. The study also compared the change from baseline in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), prandial, basal, and total daily insulin, 7-point self-monitored blood glucose (SMBG) profiles, immunogenicity, and adverse events (AEs) including hypoglycemia., Results: In total, 478 patients were included in the intent-to-treat analysis (MYL-1601D: 238; Ref-InsAsp-US: 240) set. The 90% confidence interval (CI) for the primary endpoint was within the pre-defined equivalence margin of ±11.7% and the treatment differences (SE) in TEAR responders between the treatment groups was - 2.86 (4.16) with 90% CI - 9.71 to 3.99. The mean (SD) changes from baseline for HbA1c, FPG, and insulin dosages were similar in both groups at week 24. The safety profiles including hypoglycemia, immune-related events, AEs, and other reported variables were similar between the treatment groups at week 24., Conclusions: MYL-1601D demonstrated similar immunogenicity, efficacy, and safety profiles to Ref-InsAsp-US in patients with T1D over 24 weeks.

Background: Cytopathological evaluation of thyroid fine-needle aspiration biopsy (FNAB) specimens can fail to raise preoperative suspicion of medullary thyroid carcinoma (MTC). The Afirma RNA-sequencing MTC classifier identifies MTC among FNA samples that are cytologically indeterminate, suspicious, or malignant (Bethesda categories III-VI). In this study we report the development and clinical performance of this MTC classifier. Methods: Algorithm training was performed with a set of 483 FNAB specimens (21 MTC and 462 non-MTC). A support vector machine classifier was developed using 108 differentially expressed genes, which includes the 5 genes in the prior Afirma microarray-based MTC cassette. Results: The final MTC classifier was blindly tested on 211 preoperative FNAB specimens with subsequent surgical pathology, including 21 MTC and 190 non-MTC specimens from benign and malignant thyroid nodules independent from those used in training. The classifier had 100% sensitivity (21/21 MTC FNAB specimens correctly called positive; 95% confidence interval [CI] = 83.9-100%) and 100% specificity (190/190 non-MTC FNAs correctly called negative; CI = 98.1-100%). All positive samples had pathological confirmation of MTC, while all negative samples were negative for MTC on surgical pathology. Conclusions: The RNA-sequencing MTC classifier accurately identified MTC from preoperative thyroid nodule FNAB specimens in an independent validation cohort. This identification may facilitate an MTC-specific preoperative evaluation and resulting treatment.

This is a single-center randomized open label active-controlled crossover trial comparing efficacy and safety of fast acting insulin aspart (FA) (FIASP ® ) versus insulin aspart (IAsp) (NovoLog ® ) when used in the Medtronic 670G system in auto mode in patients with type 1 diabetes. Forty patients were randomized to either IAsp or FA. Each treatment period was 7 weeks and a standardized meal test was administered 6 weeks after the start of each treatment period. The primary endpoint was postprandial glucose (PPG) increment after the meal test at 1 h. Treatment with FA using the MiniMed 670G hybrid closed loop (HCL) led to a greater reduction in 1-h postprandial glucose increase compared with treatment with IAsp during the standardized mixed meal test. Change in glucose: [estimated treatment difference (ETD ± standard deviation [SD]); 95% confidence interval]: 70.27 (±17.36) mg/dL (3.9 ± 1.0 mmol/L) with FA versus 98.42 (±17.36) mg/dL (5.5 ± 1.0 mmol/L) with IAsp ( P  = 0.008). Patients spent 1.81% ( P  = 0.016) more time (equivalent to 26 min per day) in the 70-180 mg/dL (3.89-9.99 mmol/L) range with FA than with IAsp. The entire sample spent only 0.5% of time <54 mg/dL (<3.0 mmol/L) range. The increment in the 1 h postmeal test glucose was significantly lower with FA versus IAsp. FA in a HCL setting is safe and effective with patients spending more time in the 70-180 mg/dL (3.89-9.99 mmol/L) target range than with IAsp. Trial registration: Clinicaltrials.gov identifier: NCT03977727.

Aims: To assess the efficacy, insulin dose, safety and immunogenicity when people with type 1 diabetes mellitus switched between MYL-1501D and reference insulin glargine (Lantus®; Sanofi-Aventis US LLC, Bridgewater, New Jersey)., Materials and Methods: Eligible participants from INSTRIDE 1 who completed 52 weeks of reference insulin glargine treatment were randomized 1:1 to the reference sequence (n = 63; reference insulin glargine for 36 weeks) or to the treatment-switching sequence (n = 64; MYL-1501D [weeks 0-12], reference insulin glargine [weeks 12-24] and MYL-1501D [weeks 24-36]). Change in glycated haemoglobin (HbA1c) from baseline to week 36 was the primary efficacy endpoint used to demonstrate equivalence between the two treatment sequences. Secondary endpoints included: change in fasting plasma glucose (FPG), self-monitored blood glucose (SMBG) and insulin dose; immunogenicity; and adverse events, including hypoglycaemia., Results: Mean changes in HbA1c (least squares [LS] mean [SE]) from baseline to week 36 were -0.05 (0.032) and -0.06 (0.034) for the treatment-switching and reference sequences, respectively (LS mean difference 0.01 [95% CI -0.085 to 0.101]). Treatment sequences were comparable in terms of secondary endpoints, including FPG, SMBG and insulin dose, and the safety and immunogenicity profiles of the two sequences were similar., Conclusions: Switching participants between MYL-1501D and reference insulin glargine demonstrated equivalent efficacy and similar safety and immunogenicity, showing that people taking reference insulin glargine can safely switch to MYL-1501D., (© 2019 The Authors.

In this post hoc analysis we investigated the effects of insulin degludec/liraglutide fixed-ratio combination (IDegLira) versus comparators on cardiovascular (CV) risk markers in participants in the DUAL II (vs. insulin degludec), DUAL V (vs. insulin glargine 100 units/mL) and DUAL VII (vs. basal-bolus therapy) trials, grouped by sex, age (<65 years, ≥65 years) and diabetes duration (<10 years, ≥10 years). Treatment contrasts were in favour of IDegLira in many subgroups for changes from baseline in glycated haemoblogin (DUAL II, DUAL V), body weight (all three trials), systolic blood pressure (BP; all three trials), HDL cholesterol (DUAL VII) and LDL cholesterol (DUAL II, DUAL V). Higher heart rates were seen with IDegLira versus comparators (all three trials) plus significantly higher diastolic BP in men (DUAL V). Differences in treatment effect were seen between sexes in waist circumference (DUAL II), systolic BP (DUAL II, DUAL V) and triglycerides (DUAL VII), and between diabetes durations in LDL cholesterol (DUAL V). In conclusion, IDegLira is associated with a general improvement in CV risk markers compared with basal insulin or basal-bolus therapy after 26 weeks of treatment., (© 2019 The Authors.

Aims: To assess the non-inferiority of MYL-1501D, a proposed biosimilar or follow-on biological agent to marketed insulin glargine, to reference insulin glargine (Lantus®; Sanofi-Aventis US LLC, Bridgewater, New Jersey) based on change in glycated hemoglobin (HbA1c)., Materials and Methods: INSTRIDE 2 was a multicentre, open-label, randomized, parallel-group, phase III non-inferiority study comparing the efficacy and safety of MYL-1501D with those of reference insulin glargine in insulin-naive and insulin-non-naive patients with type 2 diabetes mellitus receiving oral antidiabetic drugs (OADs). The primary efficacy endpoint was change in HbA1c from baseline to week 24. Secondary endpoints included metabolic readouts (eg, changes in fasting plasma glucose, insulin dosage, self-monitored blood glucose), immunogenicity and adverse events, including hypoglycaemia and nocturnal hypoglycaemic events., Results: In all, 560 patients were randomized to MYL-1501D or insulin glargine in combination with OADs for 24 weeks. The mean change in HbA1c from baseline to week 24 was -0.60% (95% CI -0.78, -0.41) and - 0.66% (95% CI -0.84, -0.48) for MYL-1501D and reference insulin glargine, respectively. MYL-1501D was well tolerated and had a safety profile similar to that of reference insulin glargine., Conclusions: Demonstration of non-inferiority between MYL-1501D and reference insulin glargine for reduction of HbA1c during 24 weeks of treatment was achieved. The two treatment groups were similar in terms of secondary endpoints, including hypoglycaemia and nocturnal hypoglycaemia, local and systemic reactions, other safety variables, and immunogenicity., (© 2018 John Wiley & Sons Ltd.)

Background: Triglyceride (TG) concentrations >2000 mg/dL are extremely elevated and increase the risk of pancreatitis., Objectives: We characterized five cases and two kindreds and ascertained prevalence in a reference laboratory population., Methods: Plasma lipids and DNA sequences of LPL, GPIHBP1, APOA5, APOC2, and LMF1 were determined in cases and two kindreds. Hypertriglyceridemia prevalence was assessed in 440,240 subjects., Results: Case 1 (female, age 28 years) had TG concentrations >2000 mg/dL and pancreatitis since infancy. She responded to diet and medium-chain triglycerides, but not medications. During two pregnancies, she required plasma exchange for TG control. She was a compound heterozygote for a p.G236Gfs*15 deletion and a p.G215E missense mutation at LPL, as was one sister with hypertriglyceridemia and pancreatitis during pregnancy. Her father was heterozygous for the deletion and had hypertriglyceridemia and recurrent pancreatitis. Other family members had either the missense mutation or the deletion, and had hypertriglyceridemia but no pancreatitis. In kindred 2, three preschool children had severe hypertriglyceridemia and were homozygous for a GPIHBP1 p.T108R missense mutation. Case 5 (male, age 43 years) presented with pancreatitis and TG levels >5000 mg/dL and had heterozygous GPIHBP1 p.G175R and APOC2 intron 2-4G>C mutations. On diet, fenofibrate, fish oil, and atorvastatin, his TG concentration was 2526 mg/dL, but normalized to <100 mg/dL with added pioglitazone. In our population study, 60 subjects (0.014%) of 440,240 had TG concentrations >2000 mg/dL, and 66.7% were diabetic and had elevated insulin levels., Conclusions: Extreme hypertriglyceridemia is rare (0.014%); and during pregnancy, it may require plasma exchange., (Copyright © 2018 National Lipid Association.

Aim: To test the safety and efficacy of MYL-1501D, a proposed insulin glargine biosimilar, in patients with type 1 diabetes mellitus (T1DM)., Methods: The safety and efficacy of MYL-1501D and reference insulin glargine were evaluated in INSTRIDE 1, a 52-week, open-label, randomized, phase III study in patients with T1DM. The primary objective was to determine whether once-daily MYL-1501D was non-inferior to once-daily insulin glargine when administered in combination with mealtime insulin lispro based on change in glycated haemoglobin (HbA1c) from baseline to week 24. Secondary endpoints were changes in fasting plasma glucose, insulin dose, self-monitored blood glucose and immunogenicity from baseline, and occurrences of hypoglycaemic, nocturnal hypoglycaemic and adverse events up to week 52., Results: Overall, 558 patients were randomized 1:1 to MYL-1501D or reference insulin glargine in combination with thrice-daily mealtime insulin lispro for 52 weeks. The mean change in HbA1c from baseline to week 24 was 0.14% (standard error [SE] 0.054; 95% confidence interval [CI] 0.033, 0.244) for MYL-1501D and 0.11% (SE 0.054; 95% CI 0.007, 0.220) for reference insulin glargine. MYL-1501D had a safety profile similar to that of reference insulin glargine and was well tolerated in patients with T1DM up to week 52., Conclusions: The upper 95% CI limit for mean change in HbA1c at week 24 indicated that MYL-1501D was non-inferior to reference insulin glargine. There were no clinically meaningful differences between groups in incidence of overall and nocturnal hypoglycaemia, local or systemic reactions, safety or immunogenicity., (© 2018 John Wiley & Sons Ltd.)

Sponsors of follow-on biologics can submit their applications for approval by the US Food and Drug Administration (FDA) under 2 distinct pathways. The submission pathway is determined by the pathway previously used by the reference biologic product, which is the biologic product upon which the follow-on product relies for evidence of safety and efficacy.

Canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor approved for the treatment of type 2 diabetes mellitus (T2DM), lowers blood glucose by inhibiting renal glucose reabsorption and increasing urinary glucose excretion. It has been reported that SGLT2 inhibitors may have potential adverse effects on bone, including increased fracture risk and decreased bone mineral density (BMD). Across clinical studies, canagliflozin was not associated with meaningful changes in serum or urine calcium, vitamin D, or parathyroid hormone. Minimal increases in serum phosphate and magnesium that were within normal limits were seen with canagliflozin versus placebo. Canagliflozin was associated with increases in serum collagen type 1 beta-carboxy telopeptide (beta-CTX), a bone resorption marker, and osteocalcin, a bone formation marker. Decreases in total hip BMD were seen with canagliflozin 100 and 300 mg versus placebo after 2 years (-1.7%, -2.1%, -0.8%; differences of -0.9% and -1.2%), but not at other skeletal sites (normal age-related bone loss, ~0.5-1.0%/year). Changes in beta-CTX and total hip BMD were significantly associated with weight loss, which is known to increase bone resorption markers and decrease BMD. Canagliflozin was associated with a higher fracture incidence in an interim analysis of the CANagliflozin cardioVascular Assessment Study (CANVAS) in patients with a history or high risk of cardiovascular disease (incidence per 100 patient-years of 1.6, 1.6, and 1.1 with canagliflozin 100 and 300 mg and placebo), but not in other clinical studies of patients with T2DM. Fractures tended to occur as early as 12 weeks after initiating treatment and were primarily located in the distal parts of the upper and lower extremities. The reason for increased fracture risk with canagliflozin treatment is unknown, but is likely not related to a direct effect of canagliflozin on bone-related biomarkers. Data from ongoing canagliflozin studies, including CANVAS, will provide additional information on fracture risk in patients with T2DM.

Objective: The primary objective was to assess the operative rate in patients with a benign result from the Afirma gene expression classifier (GEC) during long-term follow-up at nonacademic medical facilities. The secondary endpoint of this study was the treating physician's opinion regarding the safety of GEC use compared to the hypothetical situation of providing thyroid nodule management without the GEC., Methods: This was a retrospective study of nonacademic medical practices utilizing the GEC. Those clinicians utilizing the GEC testing who had three or more 'benign' results during the data collection period (September 2010 through June 2014) were invited to participate. Operative status and patient demographics were documented for patients with GEC testing at least 36 months (± 3 months) prior to the date of data collection. A survey also was administered to the treating physicians to assess their perceived safety of using the GEC in patient care., Results: During 36 months (± 3 months) of follow-up, 17 of 98 patients (17.3%) with a 'benign' GEC result underwent surgery. Within the first 2 years after a 'benign' GEC, 88% of surgeries were performed. Regarding safety of the GEC, the treating physicians reported that patient safety was improved by using the GEC compared to not using the GEC in 78 of 91 cases (86%)., Conclusion: It appears that a 'benign' result on the GEC is associated with a reduction in the rate of thyroid surgeries compared to published data when patients are followed for 36 months after testing. A nonoperative approach to follow-up was felt to be a safe alternative to diagnostic surgery by the majority of responsible physicians in the study., Abbreviations: AUS = atypia of undetermined significance FLUS = follicular lesion of undetermined significance FN = follicular neoplasm FNA = fine-needle aspiration GEC = gene expression classifier.

Aims: To compare the immunogenicity profiles and the potential effects on clinical outcomes of LY2963016 insulin glargine (LY IGlar) and Lantus® insulin glargine (IGlar), products with identical primary amino acid sequences, in patients with type 1 or type 2 diabetes mellitus (T1DM or T2DM)., Methods: To assess immunogenicity, anti-insulin glargine antibodies (measured as percent binding) were compared between treatments in 52-week (open-label) and 24-week (double-blind) randomized studies in total study populations of patients with T1DM (N = 535) and T2DM (N = 756), respectively, and two subgroups of patients with T2DM: insulin-naïve patients and those reporting prestudy IGlar treatment (prior IGlar). Relationships between insulin antibody levels and clinical outcomes were assessed using analysis of covariance and partial correlations. Insulin antibody levels were assessed using Wilcoxon rank sum. Treatment comparisons for treatment-emergent antibody response (TEAR) and incidence of detectable antibodies were analysed using Fisher's exact test., Results: No significant treatment differences were observed for insulin antibody levels, incidence of detectable anti-insulin glargine antibodies, or incidence of TEAR [overall and endpoint, by last-observation-carried-forward (LOCF)] in patients with T1DM or patients with T2DM, including the insulin-naïve subgroup. A statistically significant difference was noted in the overall incidence of detectable antibodies but not at endpoint (LOCF) nor in TEAR for the prior IGlar subgroup of patients with T2DM. Insulin antibody levels were low (<5%) in both treatment groups. Insulin antibody levels or developing TEAR was not associated with clinical outcomes., Conclusions: LY IGlar and IGlar have similar immunogenicity profiles; anti-insulin glargine antibody levels were low for both treatments, with no observed effect on efficacy and safety outcomes., (© 2015 The Authors.

Aims: To compare the efficacy and safety of LY2963016 insulin glargine (LY IGlar) and the reference product (Lantus®) insulin glargine (IGlar) in patients with type 1 diabetes (T1D)., Methods: This phase III, randomized, open-label, 52-week study enrolled patients with T1D [glycated haemoglobin (HbA1c) ≤11%] being treated with basal (once-daily) and bolus insulin. Patients were randomized to receive once-daily LY IGlar (n = 268) or IGlar (n = 267) in combination with mealtime insulin lispro for 52 weeks. The primary efficacy outcome was to test the non-inferiority (0.4% and then 0.3% margin) of LY IGlar to IGlar as measured by change in HbA1c from baseline to 24 weeks., Results: Both treatment groups had similar and significant (p < 0.001) within-group decreases in mean HbA1c values from baseline. LY IGlar met the non-inferiority criteria compared with IGlar for change in HbA1c from baseline to 24 weeks [-0.35 vs -0.46%, least-squares mean difference 0.108% (95% confidence interval -0.002 to 0.219), p > 0.05]. There were no significant (p > 0.05) treatment differences in other efficacy measures, including proportion of patients reaching HbA1c <7%, daily mean blood glucose, and insulin dose at 24 and 52 weeks. At 52 weeks, similar findings were observed between LY IGlar and IGlar for safety outcomes, including adverse events, allergic reactions, hypoglycaemia, weight change and insulin antibodies., Conclusions: Both LY IGlar and IGlar, when used in combination with mealtime insulin lispro, provided effective and similar glucose control and similar safety profiles., (© 2015 The Authors.

Objective: Insulin degludec/liraglutide (IDegLira) is a novel combination of insulin degludec (IDeg) and liraglutide. This trial investigated the contribution of the liraglutide component of IDegLira versus IDeg alone on efficacy and safety in patients with type 2 diabetes., Research Design and Methods: In a 26-week, double-blind trial, patients with type 2 diabetes (A1C 7.5-10.0% [58-86 mmol/mol]) on basal insulin (20-40 units) and metformin with or without sulfonylurea/glinides were randomized (1:1) to once-daily IDegLira + metformin or IDeg + metformin with titration aiming for fasting plasma glucose between 4 and 5 mmol/L. Maximum allowed doses were 50 dose steps (equal to 50 units IDeg plus 1.8 mg liraglutide) and 50 units for IDeg. The primary end point was change in A1C from baseline., Results: A total of 413 patients were randomized (mean A1C 8.8% [73 mmol/mol]; BMI 33.7 kg/m2). IDeg dose, alone or as part of IDegLira, was equivalent (45 units). A1C decreased by 1.9% (21 mmol/mol) with IDegLira and by 0.9% (10 mmol/mol) with IDeg (estimated treatment difference -1.1% [95% CI -1.3, -0.8], -12 mmol/mol [95% CI -14, -9; P < 0.0001). Mean weight reduction with IDegLira was 2.7 kg vs. no weight change with IDeg, P < 0.0001. Hypoglycemia incidence was comparable (24% for IDegLira vs. 25% for IDeg). Overall adverse events were similar, and incidence of nausea was low in both groups (IDegLira 6.5% vs. IDeg 3.5%)., Conclusions: IDegLira achieved glycemic control superior to that of IDeg at equivalent insulin doses without higher risk of hypoglycemia and with the benefit of weight loss. These findings establish the efficacy and safety of IDegLira and the distinct contribution of the liraglutide component., (© 2014 by the American Diabetes Association.

Background: Molecular testing for oncogenic gene mutations and chromosomal rearrangements plays a growing role in the optimal management of thyroid nodules, yet lacks standardized testing modalities and systematic validation data. Our objective was to assess the performance of molecular cytology on preoperative thyroid nodule fine-needle aspirates (FNAs) across a broad range of variables, including independent collection sites, clinical practices, and anatomic pathology interpretations., Methods: Single-pass FNAs were prospectively collected from 806 nodules 1 cm or larger by ultrasonography at five independent sites across the United States. Specimens were shipped in a nucleic acid stabilization solution and tested at a centralized clinical laboratory. Seventeen genetic alterations (BRAF, KRAS, HRAS, and NRAS mutations, PAX8-PPARG and RET-PTC rearrangements) were evaluated by multiplex polymerase chain reaction and liquid bead array cytometry in 769 FNAs that met inclusion criteria. Cytology, histology, and clinical care followed local procedures and practices. All results were double-blinded., Results: Thirty-two specimens (4.2%) failed to yield sufficient nucleic acid to generate molecular data. A single genetic alteration was detected in 80% of cytology malignant cases, 21% of indeterminate, 7.8% of nondiagnostic, and 3.5% of benign cases. Among 109 nodules with surgical histology reference standard, oncogenic mutations were present in 50% of malignant nodules missed by cytology. There were 14 cancers not identified by cytology or molecular tests, including 5 carcinomas with histologic sizes less than 1 cm (3 multifocal) and 8 noninvasive follicular variants of papillary carcinoma (4 encapsulated). No mutations were detected in 89% of the nodules benign by histopathology with 6 false-positive molecular results in 5 adenomas (2-5.5 cm) and 1 cystic nodule with an incidental papillary microcarcinoma (0.15 cm). The posttest probability of thyroid cancer was 100% for nodules positive for BRAF or RET-PTC, 70% for RAS or PAX8-PPARG, and 88% for molecular cytology overall., Conclusions: Centralized and standardized molecular testing for genetic alterations associated with a high risk of malignancy efficiently complements the local cytopathologic diagnosis of thyroid nodule aspirates in the clinical setting. Actionable molecular cytology can improve the personalized surgical and medical management of patients with thyroid cancers, facilitating one-stage total thyroidectomy and reducing the number of unnecessary diagnostic surgeries.

Aims: To compare efficacy and safety of two, once-daily basal insulin formulations [insulin lispro protamine suspension (ILPS) vs. insulin glargine (glargine)] added to oral antihyperglycaemic medications (OAMs) and exenatide BID in suboptimally controlled type 2 diabetes (T2D) patients., Methods: This 24-week, open-label, multicentre trial randomized patients to bedtime ILPS (n = 171) or glargine (n = 168). Non-inferiority of ILPS versus glargine was assessed by comparing the upper limit of 95% confidence intervals (CIs) for change in haemoglobin A1c (HbA1c) from baseline to week 24 (adjusted for baseline HbA1c) with non-inferiority margin 0.4%., Results: Non-inferiority of ILPS versus glargine was demonstrated: least-squares mean between-treatment difference (ILPS minus glargine) (95% CI) was 0.22% (0.06, 0.38). Mean HbA1c reduction was less for ILPS- versus glargine-treated patients (-1.16 ± 0.84 vs. -1.40 ± 0.97%, p = 0.008). Endpoint HbA1c < 7.0% was achieved by 53.7% (ILPS) and 61.7% (glargine) (p = NS). Overall hypoglycaemia rates (p = NS) and severe hypoglycaemia incidence (p = NS) were similar. Nocturnal hypoglycaemia rate was higher in patients treated with ILPS versus glargine (p = 0.004). Weight gain was similar between groups (ILPS: 0.27 ± 3.38 kg; glargine: 0.66 ± 3.93 kg, p = NS). Endpoint total insulin doses were lower in patients treated with ILPS versus glargine (0.30 ± 0.17 vs. 0.37 ± 0.17 IU/kg/day, p < 0.001)., Conclusions: ILPS was non-inferior to glargine for HbA1c change over 24 weeks, but was associated with less HbA1c reduction and more nocturnal hypoglycaemia. Treat-to-target basal insulin therapy improves glycaemic control and is associated with minimal weight gain when added to OAMs and exenatide BID for suboptimally controlled T2D., (© 2013 The Authors.

Context: Hashimoto's thyroiditis is less prevalent in tobacco smokers. Anatabine, an alkaloid found in Solanaceae plants including tobacco, has been reported to ameliorate a mouse model of Hashimoto's thyroiditis., Objective: The effects of anatabine in patients with Hashimoto's thyroiditis were studied., Design, Setting, Patients, and Intervention: This was a double-blind, randomized, placebo-controlled multisite study. A total of 146 patients (70 treated with anatabine and 76 with placebo) completed the study. Approximately 50% of patients in each group were taking levothyroxine. Anatabine lozenges (9-24 mg/d) or placebo, each containing vitamins A and D3, were administered orally 3 times a day for 3 months., Main Outcome Measures: Serum thyroperoxidase antibody (TPOAb) and thyroglobulin antibody (TgAb) levels were assessed. Safety was assessed through adverse events, clinical laboratory evaluations, and vital sign measurements., Results: Anatabine-treated patients had a significant reduction in absolute serum TgAb levels from baseline by study end relative to those receiving placebo (P=.027); however, there were no significant changes or differences in treatment group means for TPOAb or TgAb levels. Mean±SD TgAb values decreased by 46.2±101.1 and 3.9±83.9 World Health Organization units for the anatabine and placebo groups, respectively. Significantly more patients had a >20% drop in TgAb levels in the anatabine than placebo group (P=.023). Overall, the anatabine supplement was safe and well tolerated, although significantly (P<.05) more patients in the anatabine group reported adverse events., Conclusions: These results demonstrate an immunological effect of anatabine on TgAb levels. Further studies are warranted to determine the longer-term effects and possible actions of anatabine on the course of Hashimoto's thyroiditis.

OBJECTIVE To compare effects of LY2605541 versus insulin glargine on daily mean blood glucose as part of a basal-bolus regimen for type 1 diabetes. RESEARCH DESIGN AND METHODS In this randomized, Phase 2, open-label, 2 × 2 crossover study, 137 patients received once-daily basal insulin (LY2605541 or glargine) plus mealtime insulin for 8 weeks, followed by crossover treatment for 8 weeks. Daily mean blood glucose was obtained from 8-point self-monitored blood glucose profiles. The noninferiority margin was 10.8 mg/dL. RESULTS LY2605541 met noninferiority and superiority criteria compared with insulin glargine in daily mean blood glucose (144.2 vs. 151.7 mg/dL, least squares mean difference = -9.9 mg/dL [90% CI -14.6 to -5.2], P < 0.001). Fasting blood glucose variability and A1C were reduced with LY2605541 compared with insulin glargine (both P < 0.001). Mealtime insulin dose decreased with LY2605541 and increased with insulin glargine. Mean weight decreased 1.2 kg with LY2605541 and increased 0.7 kg with insulin glargine (P < 0.001). The total hypoglycemia rate was higher for LY2605541 (P = 0.04) and the nocturnal hypoglycemia rate was lower (P = 0.01), compared with insulin glargine. Adverse events (including severe hypoglycemia) were similar, although more gastrointestinal-related events occurred with LY2605541 (15% vs. 4%, P < 0.001). Mean changes (all within normal range) were higher for alanine aminotransferase, aspartate aminotransferase, triglycerides, and LDL-cholesterol and lower for HDL-cholesterol with LY2605541 compared with insulin glargine (all P < 0.02). CONCLUSIONS In type 1 diabetes, compared with insulin glargine, LY2605541, a novel, long-acting basal insulin, demonstrated greater improvements in glycemic control, increased total hypoglycemia, and reduced nocturnal hypoglycemia, as well as reduced weight and lowered mealtime insulin doses.

Professional continuous glucose monitoring (PCGM) is a 3-5 day test done to evaluate diabetes control. The PCGM test uses interstitial glucose measurements done every 5 min with a glucose-oxidase-impregnated membrane. The PCGM test evaluates glucose control retrospectively with the glucose results being unknown to the patient until the results are downloaded after the testing period. The PCGM test allows the practitioner and patient to evaluate the effect of diet, physical activity, medications, and lifestyle events on glucose control during the 24 h period. Developing a PCGM program at a medical office involves understanding reimbursement issues and having trained staff and a process in place to initiate the test and download and interpret the data., ((c) 2010 Diabetes Technology Society.)

Objective: To present the findings in a randomized, parallel-group study, comparing once-daily insulin glargine with twice-daily NPH insulin in patients with type 1 diabetes previously treated with multiple daily injections of basal and regular insulin., Methods: Of 394 patients with type 1 diabetes treated for up to 28 weeks, 195 received insulin glargine and 199 received NPH insulin, in addition to preprandial regular insulin. Glycemic control and hypoglycemic episodes were assessed., Results: A greater mean decrease in fasting blood glucose (FBG) was achieved at endpoint with insulin glargine than with NPH insulin (-21 mg/dL versus -10 mg/dL [-1.17 mmol/L versus -0.56 mmol/L]; P = 0.015), and a greater percentage of patients treated with insulin glargine reached the target FBG (32.6% versus 21.3%; P = 0.015). Similar percentages of patients in both treatment groups achieved glycosylated hemoglobin values of 7.0% or less at endpoint (insulin glargine, 35.8%; NPH insulin, 35.4%). After the 1-month titration phase, the percentage of patients who reported at least one symptomatic hypoglycemic event confirmed by a blood glucose value of less than 50 mg/dL (2.8 mmol/L) was significantly lower with insulin glargine than with NPH insulin (73.3% versus 81.7%; P = 0.021). Furthermore, the percentage of patients who reported at least one symptomatic hypoglycemic event confirmed by a blood glucose value of less than 36 mg/dL (2.0 mmol/L) was significantly lower with insulin glargine than with NPH insulin (36.6% versus 46.2%; P = 0.033)., Conclusion: Once-daily insulin glargine was at least as effective as twice-daily NPH insulin in improving fasting glycemic control and resulted in fewer reported symptomatic hypoglycemic events.

Growth of Escherichia coli in medium containing leucine results in increased entry of exogenously supplied tripeptides into the bacterial cell. This leucine-mediated elevation of peptide transport required expression of the trp-linked opp operon and was accompanied by increased sensitivity to toxic tripeptides, by an enhanced capacity to utilize nutritional peptides, and by an increase in both the velocity and apparent steady-state level of L-[U-14C]alanyl-L-alanyl-L-alanine accumulation for E. coli grown in leucine-containing medium relative to these parameters of peptide transport measured with bacteria grown in media lacking leucine. Direct measurement of opp operon expression by pulse-labeling experiments demonstrated that growth of E. coli in the presence of leucine resulted in increased synthesis of the oppA-encoded periplasmic binding protein.
