Dapagliflozin add-on to metformin in type 2 diabetes inadequately controlled with metformin:a randomized, double-blind, placebo-controlled 102-week trial

Background: Management of type 2 diabetes with metformin often does not provide adequate glycemic control, thereby necessitating add-on treatment. In a 24-week clinical trial, dapagliflozin, an investigational sodium glucose cotransporter 2 inhibitor, improved glycemic control in patients inadequately controlled with metformin. The present study is an extension that was undertaken to evaluate dapagliflozin as long-term therapy in this population.Methods: This was a long-term extension (total 102 weeks) of a 24-week phase 3, multicenter, randomized, placebo-controlled, double-blind, parallel-group trial. Patients were randomly assigned (1:1:1:1) to blinded daily treatment (placebo, or dapagliflozin 2.5 to 5, or 10 mg) plus open-label metformin (=1,500 mg). The previously published primary endpoint was change from baseline in glycated hemoglobin (HbA1c) at 24 weeks. This paper reports the follow-up to week 102, with analysis of covariance model performed at 24 weeks with last observation carried forward; a repeated measures analysis was utilized to evaluate changes from baseline in HbA1c, fasting plasma glucose (FPG), and weight.Results: A total of 546 patients were randomized to 1 of the 4 treatments. The completion rate for the 78-week double-blind extension period was lower for the placebo group (63.5%) than for the dapagliflozin groups (68.3% to 79.8%). At week 102, mean changes from baseline HbA1c (8.06%) were +0.02% for placebo compared with -0.48% (P = 0.0008), -0.58% (P

Sustained efficacy of dapagliflozin when added to metformin in type 2 diabetes inadequately controlled by metformin monotherapy

Background and aims: The selective SGLT2 inhibitor dapagliflozin (DAPA) reduces hyperglycaemia independently of insulin secretion or action by inhibiting renal glucose reabsorption. This study (MB102014) is a randomised double-blind, placebo (PBO)-controlled trial of DAPA added to metformin (MET) in T2DM (n=546) inadequately controlled with MET alone. Previously reported short-term data at week 24 showed significant mean reductions in the primary [HbA1c] and secondary [fasting plasma glucose (FPG) and weight] endpoints with DAPA compared to PBO. Here we report efficacy and safety results at week 102 of the long-term extension. Materials and methods: Patients aged 18-77 years with HbA1c 7-10% received DAPA 2.5 mg, 5 mg, 10 mg or PBO, plus open-label MET (≥1500mg/d). Exploratory endpoints at week 102 included changes from baseline in HbA1c, FPG and weight, and were analyzed by longitudinal repeated measures analysis. Results: Overall 71.2% of patients completed 102 weeks of the study; fewer on PBO (63.5%) than on DAPA 2.5 mg, 5 mg, and 10 mg (68.3%, 73.0%, 79.8%), due mainly to more patients on PBO discontinuing for lack of efficacy. At week 102, all DAPA groups showed greater mean reductions from baseline in HbA1c, FPG and weight compared to PBO (table), effects that were similar to those observed at week 24 and maintained throughout the trial. More patients at week 102 also achieved a therapeutic response of HbA1c<7% with DAPA 2.5 mg, 5 mg, and 10 mg (20.7%, 26.4%, 31.5%) than with PBO (15.4%). Adverse events (AEs), serious AEs and AEs leading to discontinuation were balanced across all groups. Signs and symptoms suggestive of genital infection (GenInf) were reported in 11.7%, 14.6%, 12.6% (DAPA 2.5 mg, 5 mg, 10 mg) and 5.1% (PBO) of patients, with 1 discontinuation due to GenInf. Signs and symptoms suggestive of urinary tract infection (UTI) were reported in 8.0%, 8.8%, 13.3% (DAPA 2.5 mg, 5 mg, 10 mg) and 8.0% (PBO), with 1 discontinuation due to UTI. No event of pyelonephritis was reported. Conclusion: In comparison to PBO, DAPA added to MET over 102 weeks demonstrated greater and sustained improvements in glycaemic control, clinically meaningful reduction in weight, and no increased risk of hypoglycaemia in patients with T2DM inadequately controlled with MET alone.

The SECURE study:long-term safety of Ranibizumab 0.5 mg in neovascular age-related macular degeneration

Objective - To evaluate long-term safety of intravitreal ranibizumab 0.5-mg injections in neovascular age-related macular degeneration (nAMD). Design - Twenty-four–month, open-label, multicenter, phase IV extension study. Participants - Two hundred thirty-four patients previously treated with ranibizumab for 12 months in the EXCITE/SUSTAIN study. Methods - Ranibizumab 0.5 mg administered at the investigator's discretion as per the European summary of product characteristics 2007 (SmPC, i.e., ranibizumab was administered if a patient experienced a best-corrected visual acuity [BCVA] loss of >5 Early Treatment Diabetic Retinopathy Study letters measured against the highest visual acuity [VA] value obtained in SECURE or previous studies [EXCITE and SUSTAIN], attributable to the presence or progression of active nAMD in the investigator's opinion). Main Outcome Measures - Incidence of ocular or nonocular adverse events (AEs) and serious AEs, mean change in BCVA from baseline over time, and the number of injections. Results - Of 234 enrolled patients, 210 (89.7%) completed the study. Patients received 6.1 (mean) ranibizumab injections over 24 months. Approximately 42% of patients had 7 or more visits at which ranibizumab was not administered, although they had experienced a VA loss of more than 5 letters, indicating either an undertreatment or that factors other than VA loss were considered for retreatment decision by the investigator. The most frequent ocular AEs (study eye) were retinal hemorrhage (12.8%; 1 event related to study drug), cataract (11.5%; 1 event related to treatment procedure), and increased intraocular pressure (6.4%; 1 event related to study drug). Cataract reported as serious due to hospitalization for cataract surgery occurred in 2.6% of patients; none was suspected to be related to study drug or procedure. Main nonocular AEs were hypertension and nasopharyngitis (9.0% each). Arterial thromboembolic events were reported in 5.6% of the patients. Five (2.1%) deaths occurred during the study, none related to the study drug or procedure. At month 24, mean BCVA declined by 4.3 letters from the SECURE baseline. Conclusions - The SECURE study showed that ranibizumab administered as per a VA-guided flexible dosing regimen recommended in the European ranibizumab SmPC at the investigator's discretion was well tolerated over 2 years. No new safety signals were identified in patients who received ranibizumab for a total of 3 years. On average, patients lost BCVA from the SECURE study baseline, which may be the result of disease progression or possible undertreatment.

Antagonistic effects of two novel GIP analogs, (Hyp3)GIP and (Hyp3)GIPLys16PAL, on the biological actions of GIP and longer-term effects in diabetic ob/ob mice

This study examines the actions of the novel enzyme-resistant, NH 2-terminally modified GIP analog (Hyp3)GIP and its fatty acid-derivatized analog (Hyp3)GIPLys16PAL. Acute effects are compared with the established GIP receptor antagonist (Pro3)GIP. All three peptides exhibited DPP IV resistance, and significantly inhibited GIP stimulated cAMP formation and insulin secretion in GIP receptor-transfected fibroblasts and in clonal pancreatic BRIN-BD11 cells, respectively. Likewise, in obese diabetic ob/ob mice, intraperitoneal administration of GIP analogs significantly inhibited the acute antihyperglycemic and insulin-releasing effects of native GIP. Administration of once daily injections of (Hyp 3)GIP or (Hyp3)GIPLys16PAL for 14 days resulted in significantly lower plasma glucose levels (P < 0.05) after (Hyp 3)GIP on days 12 and 14 and enhanced glucose tolerance (P < 0.05) and insulin sensitivity (P < 0.05 to P < 0.001) in both groups by day 14. Both (Hyp3)GIP and (Hyp3)GIPLys16PAL treatment also reduced pancreatic insulin (P < 0.05 to P < 0.01) without affecting islet number. These data indicate that (Hyp3)GIP and (Hyp 3)GIPLys16PAL function as GIP receptor antagonists with potential for ameliorating obesity-related diabetes. Acylation of (Hyp 3)GIP to extend bioactivity does not appear to be of any additional benefit. Copyright © 2007 the American Physiological Society.

Pain management programmes for non-English-speaking black and minority ethnic groups with long-term or chronic pain

Increasing ethnic diversity in the UK means that there is a growing need for National Health Service care to be delivered to non-English-speaking patients. The aims of the present systematic review were to: (1) better understand the outcomes of chronic pain management programmes (PMPs) for ethnic minority and non-English-speaking patients and (2) explore the perspectives on and experiences of chronic pain for these groups. A systematic review identified 26 papers meeting the inclusion criteria; no papers reported on the outcomes of PMPs delivered in the UK. Of the papers obtained, four reported on PMPs conducted outside the UK; eight reported on ethnic differences in patients seeking support from pain management services in America; and the remaining papers included literature reviews, an experimental pain study, a collaborative enquiry, and a survey of patient and clinician ratings of pain. The findings indicate a lack of research into UK-based pain management for ethnic minorities and non-English-speaking patients. The literature suggests that effective PMPs must be tailored to meet cultural experiences of pain and beliefs about pain management. There is a need for further research to explore these cultural beliefs in non-English-speaking groups in the UK. Culturally sensitive evaluations of interpreted PMPs with long-term follow-up are needed to assess the effectiveness of current provision. Copyright © 2015 John Wiley & Sons, Ltd.
