Glucodynamics of long-acting basal insulin peglispro compared with insulin glargine at steady state in patients with type 1 diabetes: substudy of a randomized crossover trial. Diabetes Obes Metab 2016; 18:1065-1071. [PMID: 27169522 DOI: 10.1111/dom.12691] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2016] [Revised: 04/29/2016] [Accepted: 05/08/2016] [Indexed: 12/01/2022]
Abstract
AIMS To compare, in an open-label, randomized, crossover phase II substudy, the glucodynamics of insulin glargine and those of basal insulin peglispro (BIL) in patients with type 1 diabetes. METHODS Patients (n = 23) underwent 24-h euglycaemic clamps after 8 weeks of treatment with glargine or with BIL. Clinically-titrated basal insulin doses (BIL group 16-64 U; glargine group 19-60 U) were administered on the morning of the clamp. RESULTS At baseline, the patients' mean ± standard deviation (s.d.) body mass index was 26.78 ± 4.20 kg/m2 and glycated haemoglobin was 7.69 ± 0.99%. The mean ± s.d. endpoint dose for the BIL group was 0.42 ± 0.13 U/kg and for the glargine group was 0.42 ± 0.10. The daily mean ± s.d. blood glucose concentration was 7.7 ± 1.2 in the BIL group and 7.9 ± 1.2 mmol/l in the glargine group (p = 0.641). The mean ± s.d. total and nocturnal hypoglycaemia rates/30 days were 2.7 ± 2.3 and 0.5 ± 0.8, respectively, for the BIL group, and 3.0 ± 2.4 and 0.7 ± 1.1, respectively, for the glargine group (p = 0.112 and 0.428). The mean glucose infusion rate (GIR) normalized to insulin unit was lower for BIL than for glargine. One patient in the glargine group and eight patients in the BIL group had minimal (<0.8 g/kg) GIRs over 24 h. The mean ± s.d. total glucose infused over 24 h (GTOT(0-24) ) was 1.22 ± 0.82 g/kg in the BIL group and 1.90 ± 1.01 g/kg in the glargine group (p = 0.002). The mean ± s.d. total glucose infused during hours 0-6 (GTOT(0-6) ) was 0.21 ± 0.22 in the BIL group and 0.41 ± 0.22 g/kg in the glargine group (p < 0.001), while the mean total glucose infused during hours 18-24 (GTOT(18-24) ) in the BIL group was 0.28 ± 0.18 g/kg and in the glargine group was 0.35 ± 0.23 g/kg (p = 0.198). The peak-to-trough ratio was 1.41 for BIL versus 2.22 for glargine. CONCLUSIONS BIL has a flatter profile than glargine, with potentially more stable metabolic control. The lower GTOT(0-24) observed in the BIL group is consistent with BIL's reduced peripheral action.

Abstract
AIMS To compare the efficacy and safety of basal insulin peglispro (BIL), which has a flat pharmacokinetic and pharmacodynamic profile and a long duration of action, with insulin glargine (GL) in patients with type 1 diabetes. MATERIALS AND METHODS In this phase III, 52-week, blinded study, we randomized 1114 adults with type 1 diabetes in a 3 : 2 distribution to receive either BIL (n = 664) or GL (n = 450) at bedtime, with preprandial insulin lispro, using intensive insulin management. The primary objective was to compare glycated haemoglobin (HbA1c) in the groups at 52 weeks, with a non-inferiority margin of 0.4%. RESULTS At 52 weeks, mean (standard error) HbA1c was 7.38 (0.03)% with BIL and 7.61 (0.04)% with GL {difference -0.22% [95% confidence interval (CI) -0.32, -0.12]; p < 0.001}. At 52 weeks more BIL-treated patients reached HbA1c <7% (35% vs 26%; p < 0.001), the nocturnal hypoglycaemia rate was 47% lower (p < 0.001) and the total hypoglycaemia rate was 11% higher (p = 0.002) than in GL-treated patients, and there was no difference in severe hypoglycaemia rate. Patients receiving BIL lost weight, while those receiving GL gained weight [difference -1.8 kg (95% CI -2.3, -1.3); p < 0.001]. Treatment with BIL compared with GL at 52 weeks was associated with greater increases from baseline in levels of serum triglyceride [difference 0.19 mmol/l (95% CI 0.11, 0.26); p < 0.001] and alanine aminotransferase (ALT) levels [difference 6.5 IU/l (95% CI 4.1, 8.9), p < 0.001], and more frequent injection site reactions. CONCLUSIONS In patients with type 1 diabetes, treatment with BIL compared with GL for 52 weeks resulted in a lower HbA1c, more patients with HbA1c levels <7%, and reduced nocturnal hypoglycaemia, but more total hypoglycaemia and injection site reactions and higher triglyceride and ALT levels.

Abstract
RIZ1 is a tumor suppressor gene. The purpose of the present study was to investigate the inhibitory effect of RIZ1 gene therapy on the growth of SiHa cervical cancer cells and its synergism with paclitaxel. The expression levels of RIZ1 were examined by real-time PCR and western blotting before and after transfection of RIZ1. The effects of paclitaxel or pcDNA3.1(+)-RIZ1 alone or in combination, on the proliferation of SiHa cells were evaluated by MTT method. The inhibitory effect on the proliferation of SiHa cells was more significant in the pcDNA3.1(+)-RIZ1 combined with paclitaxel group than in the pcDNA3.1(+)-RIZ1 or paclitaxel groups (P<0.05). The expression level of RIZ1 in SiHa cells increased after treatment with paclitaxel, which indicated a synergism between them. RIZ1 gene therapy combined with paclitaxel showed stronger cell inhibition than paclitaxel alone, which indicated a synergism between them.

Abstract
Physicochemical properties of coordination compounds can be exploited for molecular recognition of biomolecules. The inherent π-π stacking properties of [Pt(chelate)(N-donor)]2+ ([PtN4]) complexes were modulated by systematic variation of the chelate (diethylenetriamine and substituted derivatives) and N-donor (nucleobase or nucleoside) in the formally substitution-inert PtN4 coordination sphere. Approaches to target the HIV nucleocapsid protein HIVNCp7 are summarized building on (i) assessment of stacking interactions with simple tryptophan or tryptophan derivatives to (ii) the tryptophan-containing C-terminal zinc finger and (iii) to the full two-zinc finger peptide and its interactions with RNA and DNA. The xanthosine nucleoside was identified as having significantly enhanced stacking capability over guanosine. Correlation of the LUMO energies of the modified nucleobases with the DFT π-stacking energies shows that frontier orbital energies of the individual monomers can be used as a first estimate of the π-stacking strength to Trp. Cellular accumulation studies showed no significant correlation with lipophilicity of the compounds, but all compounds had very low cytotoxicity suggesting the potential for antiviral selectivity. The conceptual similarities between nucleobase alkylation and platination validates the design of formally substitution-inert coordination complexes as weak Lewis acid electrophiles for selective peptide targeting.

Abstract
Basal insulin peglispro (BIL) is a novel basal insulin with a flat, prolonged activity profile. BIL has been demonstrated in a dog model, in healthy men and in patients with type 1 diabetes (T1D) to have significant hepato-preferential action resulting from reduced peripheral activity. In the IMAGINE-Phase 3 clinical trial program, more than 6000 patients were included, of whom ~3900 received BIL. Of the 7 pivotal IMAGINE trials, 3 studies were double-blinded and 3 were in T1D patients. BIL consistently demonstrated a greater HbA1c reduction, less glycaemic variability and a clinically relevant reduction in the rates of nocturnal hypoglycaemia across comparator [glargine and isophane insulin (NPH)] studies. Trials using basal/bolus regimens had higher rates of total hypoglycaemia with BIL due to higher rates of daytime hypoglycaemia. Severe hypoglycaemia rates were similar to comparator among both patients with T1D or type 2 diabetes (T2D). T1D patients lost weight compared with glargine (GL). Patients with T2D tended to gain less weight with BIL than with glargine. Compared to glargine, BIL was associated with higher liver fat, triglycerides and alanine aminotransferase (ALT) levels, including a higher frequency of elevation of ALT ≥3 times the upper limit of normal, but without severe, acute drug-induced liver injury. Injection site reactions, primarily lipohypertrophy, were more frequent with BIL. In conclusion, BIL demonstrated better glycaemic control with reduced glucose variability and nocturnal hypoglycaemia but higher triglycerides, ALT and liver fat relative to conventional comparator insulin. The hepato-preferential action of BIL with reduced peripheral activity may account for these findings.

Abstract
AIMS The primary objective was to demonstrate that basal insulin peglispro (BIL) was non-inferior compared with insulin glargine (GL) for haemoglobin A1c (HbA1c) at 26 weeks with a non-inferiority margin of 0.4%. MATERIALS AND METHODS IMAGINE 1 was a Phase 3, open-label, parallel-arm study conducted in nine countries. Adults with type 1 diabetes (n = 455) were randomized (2:1) to bedtime BIL or GL in combination with prandial insulin lispro for 78 weeks, with a primary endpoint of 26 weeks. An electronic diary facilitated data capture and insulin dosing calculations for intensive insulin management. RESULTS At 26 weeks, mean HbA1c was 7.06% ± 0.04% and 7.43% ± 0.06% for patients assigned to BIL (N = 295) and GL (N = 160), respectively (difference -0.37% [95% CI: -0.50 to -0.23], P < .001); more patients on BIL achieved HbA1c <7% (44.9% vs 27.5%, P < .001). Compared with GL, patients using BIL lost weight, with lower fasting serum glucose and between-day fasting blood glucose variability, and 36% less nocturnal hypoglycemia, 29% more total hypoglycemia and more severe hypoglycemia. Total and prandial insulin doses were lower with BIL; basal insulin doses were higher. Alanine aminotransferase increased with BIL, with more patients having elevations ≥3 × ULN. BIL treatment was associated with more frequent injection site reactions and an increase from baseline in serum triglycerides. CONCLUSIONS In patients with type 1 diabetes, treatment with BIL compared to GL for 26 weeks was associated with lower HbA1c, less nocturnal hypoglycemia, lower glucose variability and weight loss. Increases in total and severe hypoglycemia, triglycerides, aminotransferases and injection site reactions were also noted.

Abstract
OBJECTIVE The development of liver fibrosis has been shown to be associated with the transition of quiescent hepatic stellate cells (HSCs) into myofibroblastic HSCs, and the Notch signaling system has been shown to be activated in this process. The Notch signaling pathway is also known to regulate epithelial-mesenchymal transition (EMT). MATERIALS AND METHODS In the current study, quiescent HSCs were examined for expression of EMT markers, and experiments were performed to determine whether these markers change as quiescent HSCs transition into myofibroblastic HSCs and whether the process is modulated by Notch signaling. To promote myofibroblastic transition under experimental conditions, enzymatic perfusion and density gradient centrifugation were used to isolate rat HSCs, which were then cultured. A γ-secretase inhibitor was used to inhibit Notch signaling pathway activity in primary rat HSCs. RESULTS Upregulated expression of myofibroblastic markers was observed, but expression of quiescent HSC markers and epithelial markers was downregulated during the transition of HSC in vitro. Data indicate that expression of the classical EMT marker; i.e., E-cadherin, was decreased and that of N-cadherin and snail 1 increased. Notch 2 and Notch 3 receptors and Hey2 and HeyL target genes expression increased significantly as quiescent HSCs transitioned into myofibroblastic HSCs. When Notch signaling was blocked, however, the myofibroblastic transition of HSCs reverted, and epithelial marker expression was restored. CONCLUSIONS Thus, targeting Notch signaling may provide new insights into the mechanism of HSC transition and may offer a possible therapeutic target for the treatment of hepatic injury.

Abstract
BACKGROUND Meta-analyses support the efficacy of cognitive-behavioural therapy (CBT) for schizophrenia in western cultures. This study aimed to compare the efficacy of CBT and supportive therapy (ST) for patients with schizophrenia in China. METHOD A multicentre randomized controlled, single-blinded, parallel-group trial enrolled a sample of 192 patients with schizophrenia. All patients were offered 15 sessions of either CBT or ST over 24 weeks and followed up for an additional 60 weeks. All measures used were standardized instruments with good reliability and validity. The Positive and Negative Syndrome Scale (PANSS) was used to assess symptoms of schizophrenia. The Schedule for Assessing Insight (SAI) was used to assess patients' insight and the Personal and Social Performance Scale (PSP) was used to assess their social functioning. RESULTS Effect-size analysis showed that patients made rapid improvements in all symptoms, insight and social functioning as measured by the PANSS, SAI and PSP at 12 and 24 weeks and maintained these improvements over the course of the study to 84 weeks. Patients in the CBT group showed significantly greater and more durable improvement in PANSS total score (p = 0.045, between-group d = 0.48), positive symptoms (p = 0.018, between-group d = 0.42) and social functioning (p = 0.037, between-group d = 0.64), with significant differences emerging after completion of therapy. CONCLUSIONS Both CBT and ST combined with medication had benefits on psychopathology, insight and social functioning of patients with schizophrenia. CBT was significantly more effective than ST on overall, positive symptoms and social functioning of patients with schizophrenia in the long term.

Abstract
The phosphate clamp is a distinct mode of ligand-DNA binding where the molecular recognition is manifested through ("non-covalent") hydrogen-bonding from am(m)ines of polynuclear platinum complexes to the phosphate oxygens on the oligonucleotide backbone. This third mode of DNA binding is unique to the "classical" DNA intercalators and minor groove binding agents and even the closely related covalently binding mononuclear and polynuclear drugs. 2D (1)H NMR studies on the Dickerson-Drew dodecamer (DDD, d(CGCGAATTCGCG)2) showed significant A-T contacts mainly on nucleotides A6, T7 and T8 implying a selective bridging from C9G10 in the 3' direction to C9G10 of the opposite strand. {(1)H, (15)N} HSQC NMR spectroscopy using the fully (15)N-labelled compound [{trans-Pt(NH2)3(H2N(CH2)6NH3}2μ-(H2N(CH2)6NH2)2(Pt(NH3)2](8+) (TriplatinNC) showed at pH 6 significant chemical shifts and (1)J((195)Pt-(15)N) coupling constants for the free drug and DDD-TriplatinNC at pH 7 indicative of formation of the phosphate clamp. (31)P NMR results are also reported for the hexamer d(CGTACG)2 showing changes in (31)P NMR chemical shifts indicative of changes around the phosphorus center. The studies confirm the DNA binding modes by substitution-inert (non-covalent) polynuclear platinum complexes and help in further establishing the chemotype as a new class of potential anti-tumour agents in their own right with a distinct profile of biological activity.

Abstract
Previous studies have reported associations between the functional FABP2 Ala54Thr (rs1799883) polymorphism and type 2 diabetes mellitus (T2DM), obesity, and metabolic syndrome in different populations with conflicting results. We investigated the association between the FABP2 Ala54Thr polymorphism and T2DM (235 cases, 431 controls), obesity (377 cases, 431 controls), and metabolic syndrome (315 cases, 323 controls) by logistic regression analysis in a Chinese study cohort recruited from Yichang, Hubei Province. We then comprehensively reviewed the association of the FABP2 Ala54Thr polymorphism with T2DM, obesity, and metabolic syndrome via meta-analysis. The strength of association was assessed by odds ratios (ORs) with 95% confidence intervals (CIs). The FABP2 Ala54Thr polymorphism was significantly associated with obesity (AT vs AA: OR = 2.633, 95%CI = 1.065-6.663, P = 0.036; TT vs AA: OR = 4.160, 95%CI = 1.609-10.757, P = 0.003) and metabolic syndrome (TT vs AA: OR = 2.273, 95%CI = 1.242-4.156, P = 0.008) by logistic regression with adjustment for covariates. However, no significant association was found between T2DM and the FABP2 Ala54Thr polymorphism. We identified 24 studies on T2DM (4517 cases, 5224 controls), 9 studies on obesity (949 cases, 2002 controls), and 6 studies on metabolic syndrome (2194 cases, 3282 controls) by literature search. The meta-analyses revealed significant associations for metabolic syndrome (T allele: OR = 1.179, 95%CI = 1.015-1.362, P = 0.031) and T2DM (T allele: OR = 1.160, 95%CI = 1.08-1.24, P < 0.001), but no association for obesity (T allele: OR = 1.069, 95%CI = 0.925-1.235, P = 0.367).
