Recently, lobeglitazone, a new TZD, was described as an antidiabetic drug that targetsthe Non-competitive inhibitors PPAR-γ (peroxisome γ proliferator-activated receptor) pathway, but no information on its effects on PTP1B have been reported to date. We investigated the effects of lobeglitazone on PTP1B activity in vitro. Surprisingly, lobeglitazone led to moderate inhibition on PTP1B (IC50 42.8 ± 3.8 µM) activity and to a non-competitive reversible mechanism of action. -
Combining a Glucagon-Like Peptide-1 Receptor Agonist with Basal Insulin: the Why and How
Combining a Glucagon-like Peptide-1 Receptor Agonist with Basal Insulin: The Why and How Case Study Mary is a 61 year-old female diagnosed with type 2 diabetes mellitus (T2DM) 8 years ago. She was initially managed with the combination of lifestyle modification and metformin. Since that time she was treated with a sulfonylurea, but it was discontinued due to symptomatic hypoglycemia. She was also treated with pioglitazone, but significant fluid retention led to it discontinuation. A year-and-a- half ago, basal insulin was added to her lifestyle and metformin management. She now administers 52 units (0.62 units/kg) once daily at bedtime. Since starting basal insulin, she has experienced 3 episodes of mild hypoglycemia. Since her diagnosis, Mary’s HbA1c has never been <7.0%; her current HbA1c is 7.9%. Over the past month, her fasting plasma glucose (FPG) has ranged from 103 mg/dL to 136 mg/dL and her postprandial glucose (PPG) from 164 mg/dL to 213 mg/dL. She has gained 2.6 kg since starting basal insulin and her body mass index is now 31 kg/m2. Her blood pressure is 134/82 mmHg. She experiences occasional tingling in her feet. Eye examination reveals grade 1 retinopathy. Current medications are: metformin 1000mg twice daily, basal insulin 52 units once daily at bedtime, and hydrochlorothiazide 25 mg once daily. Her family physician notes that Mary’s FPG is reasonably well-controlled, yet her HbA1c and PPG remain elevated. He is also concerned about her episodes of hypoglycemia and weight gain and the evidence indicating microvascular damage. -

IHS PROVIDER September 2017
September 2017 Volume 42 Number 9 Indian Health Service National Pharmacy and Therapeutics Committee SGLT-2 inhibitors (Update) NPTC Formulary Brief August Meeting 2017 Background: The FDA has currently approved three SGLT-2 inhibitors, two of which have completed FDA-mandated cardiovascular outcomes trials. Last year, in the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG), empagliflozin not only reduced cardiovascular events, but also mortality.1 This year, the Canagliflozin Cardiovascular Assessment Study (CANVAS) demonstrated equivocal cardiovascular benefits, no mortality benefit, and significant harms in those receiving canagliflozin.2 The DECLARE-TIMI 58 cardiovascular study of dapagliflozin will be completed in April 2019 (ClinicalTrials.gov Identifier: NCT01730534). Uncertainty remains regarding the current data, long- term benefits and harms, and differentiation among SGLT-2 inhibitors. Following a review of SGLT2 inhibitors at the August 2017 NPTC meeting on their cardiovascular outcomes, net benefit and place in therapy, no modifications were made to the National Core Formulary (NCF). Discussion: EMPA-REG enrolled 7,020 patients with Type 2 diabetes mellitus (T2DM) and HgbA1c values between 7.0-10.0%. All patients had established cardiovascular disease (CVD) and were observed for a median duration of 3.1 years. Empagliflozin reduced the primary outcome of cardiovascular (CV) death, nonfatal myocardial infarction (MI), or nonfatal cardiovascular accident (CVA) by 6.5 events per 1000 patient-years (pt-yrs). Mortality decreased by 9.2 events per 1000 pt-yrs, primarily driven by a reduction in CV mortality of 7.8 events per 1000 pt-yrs. Heart failure hospitalization decreased by 5.1 events per 1000 pt-yrs. -

AVANDIA® (Rosiglitazone Maleate) Tablets
PRESCRIBING INFORMATION AVANDIA® (rosiglitazone maleate) Tablets WARNING: CONGESTIVE HEART FAILURE ● Thiazolidinediones, including rosiglitazone, cause or exacerbate congestive heart failure in some patients (see WARNINGS). After initiation of AVANDIA, and after dose increases, observe patients carefully for signs and symptoms of heart failure (including excessive, rapid weight gain, dyspnea, and/or edema). If these signs and symptoms develop, the heart failure should be managed according to current standards of care. Furthermore, discontinuation or dose reduction of AVANDIA must be considered. ● AVANDIA is not recommended in patients with symptomatic heart failure. Initiation of AVANDIA in patients with established NYHA Class III or IV heart failure is contraindicated. (See CONTRAINDICATIONS and WARNINGS.) DESCRIPTION AVANDIA (rosiglitazone maleate) is an oral antidiabetic agent which acts primarily by increasing insulin sensitivity. AVANDIA is used in the management of type 2 diabetes mellitus (also known as non-insulin-dependent diabetes mellitus [NIDDM] or adult-onset diabetes). AVANDIA improves glycemic control while reducing circulating insulin levels. Pharmacological studies in animal models indicate that rosiglitazone improves sensitivity to insulin in muscle and adipose tissue and inhibits hepatic gluconeogenesis. Rosiglitazone maleate is not chemically or functionally related to the sulfonylureas, the biguanides, or the alpha-glucosidase inhibitors. Chemically, rosiglitazone maleate is (±)-5-[[4-[2-(methyl-2- pyridinylamino)ethoxy]phenyl]methyl]-2,4-thiazolidinedione, (Z)-2-butenedioate (1:1) with a molecular weight of 473.52 (357.44 free base). The molecule has a single chiral center and is present as a racemate. Due to rapid interconversion, the enantiomers are functionally indistinguishable. The structural formula of rosiglitazone maleate is: The molecular formula is C18H19N3O3S•C4H4O4. -
SGLT2) Inhibitors (Gliflozins) in Adults with Type 2 Diabetes (T2DM
Sodium-glucose cotransporter-2 (SGLT2) inhibitors (Gliflozins) in Adults with Type 2 Diabetes (T2DM) There are currently four SGLT2 inhibitors (canagliflozin, dapagliflozin, empagliflozin and ertugliflozin) licensed in the UK for the management of adults with T2DM. No head to head trials between the SGLT2 inhibitors have been conducted. As at December 2019, clinical outcome data is available for three of the four SGLT2 inhibitors around their cardiovascular effects in people with T2DM. Ertugliflozin is still to report on this data. This document summarises the key prescribing considerations. NICE Technology Appraisal Recommendation NICE makes recommendations for when SGLT2 inhibitors can be considered in adults with T2DM; Hertfordshire Medicines Management Committee Recommendations are in line with NICE guidance: Monotherapy NICE TA 390: Canagliflozin, Dapagliflozin and Empagliflozin and NICE TA 572: Ertugliflozin as monotherapies for treating T2DM Monotherapy recommended as option in adults for whom metformin is contraindicated or not tolerated and when diet & exercise alone do not provide adequate glycaemic control, only if: •a DPP‑4 inhibitor would otherwise be prescribed and •a sulfonylurea or pioglitazone is not appropriate. Dual therapy NICE TA 315: Canagliflozin, NICE TA288: Dapagliflozin, TA 336: Empagliflozin, TA 572: Ertugliflozin as combination therapies for treating T2DM In a dual therapy regimen in combination with metformin is recommended as an option, only if: •a sulfonylurea is contraindicated or not tolerated or •the person is at significant risk of hypoglycaemia or its consequences. In combination with insulin NICE TA 315: Canagliflozin, NICE TA288: Dapagliflozin, TA 336: Empagliflozin in combination with insulin with or without other antidiabetic drugs is recommended as an option. -
