What Next After Metformin? Thinking Beyond Glycaemia: Are SGLT2 Inhibitors the Answer?

ABSTRACT: The prevalence of type 2 diabetes continues to increase, along with a proliferation of glucose-lowering treatment options. There is universal agreement in the clinical community for the use of metformin as the first-line glucose-lowering therapy for the majority of patients. However, controversy exists regarding the choice of second-line therapy once metformin is no longer effective. The most recent treatment consensus focuses on the presence of cardiovascular disease, heart failure or kidney disease as a determinant of therapy choice. The majority of patients in routine practice, however, do not fall into such categories. Heart failure and kidney disease represent significant clinical and cost considerations in patients with type 2 diabetes and have a close pathophysiological association. Recent data has illustrated that sodium-glucose transporter 2 (SGLT2) inhibitor therapy can reduce the burden of heart failure and the progression of renal disease across a wide range of patients including those with and without established disease, supported by an increased understanding of the mechanistic effects of these agents. Furthermore, there is growing evidence to illustrate the overall safety profile of this class of agents and support the benefit-risk profile of SGLT2 inhibitors as a preferred option following metformin monotherapy failure, with respect to both kidney disease progression and heart failure outcomes.

SGLT2 Inhibitors: Cardiovascular Benefits Beyond HbA1c-Translating Evidence into Practice.

Project description:Cardiovascular disease (CVD), including heart failure (HF), is a leading cause of morbidity and mortality in people with type 2 diabetes mellitus (T2DM). CVD and T2DM share common risk factors for development and progression, and there is significant overlap between the conditions in terms of worsening outcomes. In assessing the cardiovascular (CV) safety profiles of anti-diabetic drugs, sodium-glucose co-transporter-2 inhibitor (SGLT2i) therapies have emerged with robust evidence for reducing the risk of adverse CVD outcomes in people with T2DM who have either established CVD or are at risk of developing CVD. A previous consensus document from the Improving Diabetes Steering Committee has examined the potential role of SGLT2is in T2DM management and considered the risk-benefit profile of the class and the appropriate place for these medicines within the T2DM pathway. This paper builds on these findings and presents practical guidance for maximising the pleiotropic benefits of this class of medicines in people with T2DM in terms of reducing adverse CVD outcomes. The Improving Diabetes Steering Committee aims to offer evidence-based practical guidance for the use of SGLT2i therapies in people with T2DM stratified by CVD risk. This is of particular importance currently because some treatment guidelines have not been updated to reflect recent evidence from cardiovascular outcomes trials (CVOTs) and real-world studies that complement the CVOTs. The Improving Diabetes Steering Committee seeks to support healthcare professionals (HCPs) in appropriate treatment selection for people with T2DM who are at risk of developing or have established CVD and examines the role of SGLT2i therapy for these people.Funding: Napp Pharmaceuticals Limited.

CHK1 inhibitors in combination chemotherapy: thinking beyond the cell cycle.

Project description:Cellular sensing of DNA damage, along with concomitant cell cycle arrest, is mediated by a great many proteins and enzymes. One focus of pharmaceutical development has been the inhibition of DNA damage signaling, and checkpoint kinases (Chks) in particular, as a means to sensitize proliferating tumor cells to chemotherapies that damage DNA. 7-Hydroxystaurosporine, or UCN-01, is a clinically relevant and well-studied kinase activity inhibitor that exerts chemosensitizing effects by inhibition of Chk1, and a multitude of Chk1 inhibitors have entered development. Clinical development of UCN-01 has overcome many initial obstacles, but the drug has nevertheless failed to show a high level of clinical activity when combined with chemotherapeutic agents. One very likely reason for the lack of clinical efficacy of Chk1 inhibitors may be that the inhibition of Chk1 causes the compensatory activation of ATM and ERK1/2 pathways. Indeed, inhibition of many enzyme activities, not necessarily components of cell cycle regulation, may block Chk1 inhibitor-induced ERK1/2 activation and enhance the toxicity of Chk1 inhibitors. This review examines the rationally hypothesized actions of Chk1 inhibitors as cell cycle modulatory drugs as well as the impact of Chk1 inhibition upon other cell survival signaling pathways. An understanding of Chk1 inhibition in multiple signaling contexts will be essential to the therapeutic development of Chk1 inhibitors.

Diabetic Agents, From Metformin to SGLT2 Inhibitors and GLP1 Receptor Agonists: JACC Focus Seminar.

Project description:Given the intersection between diabetes mellitus and cardiovascular disease (CVD), pharmacologic agents used to treat type 2 diabetes mellitus must show cardiovascular safety. Comorbid conditions, including heart failure and chronic kidney disease, are increasingly prevalent in patients with diabetes; therefore, they also play a large role in drug safety. Although biguanides, sulfonylurea, glitazones, and dipeptidyl peptidase 4 inhibitors have variable effects on cardiovascular events, sodium glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists have consistently shown safety and reduction in cardiovascular events in patients with established CVD. These medications are becoming essential tools for cardioprotection for patients with diabetes and CVD. They may also have roles in primary prevention and renal protection. This paper will review the cardiovascular impact, adverse effects, and possible mechanisms of action of pharmacologic agents used to treat patients with type 2 diabetes.

SGLT2 inhibitors and zebrafish

Project description:The CANVAS program revealed that the SGLT2 inhibitor canagliflozin increases the risk for lower-limb (minor) amputations in type 2 diabetics about a two-fold. On the contrary, the large RCTs with empagliflozin and dapagliflozin did not demonstrate a similar observation. Thus, a question arises whether the increased risk for minor amputations is associated only with canagliflozin or whether it is a class effect of SGLT2 inhibitors. Vascular disorders including defective angiogenesis are among the leading causes of lower-limb amputations. Therefore, here we examined the effects of empagliflozin, dapagliflozin, and canagliflozin on angiogenesis using zebrafish embryos and HUVECs.

Development of SGLT1 and SGLT2 inhibitors.

Project description:Sodium-glucose cotransporters SGLT1 (encoded by SGLT1, also known as SLC5A1) and SGLT2 (encoded by SGLT2, also known as SLC5A2) are important mediators of epithelial glucose transport. While SGLT1 accounts for most of the dietary glucose uptake in the intestine, SGLT2 is responsible for the majority of glucose reuptake in the tubular system of the kidney, with SGLT1 reabsorbing the remainder of the filtered glucose. As a consequence, mutations in the SLC5A1 gene cause glucose/galactose malabsorption, whereas mutations in SLC5A2 are associated with glucosuria. Since the cloning of SGLT1 more than 30 years ago, big strides have been made in our understanding of these transporters and their suitability as drug targets. Phlorizin, a naturally occurring competitive inhibitor of SGLT1 and SGLT2, provided the first insights into potential efficacy, but its use was hampered by intestinal side effects and a short half-life. Nevertheless, it was a starting point for the development of specific inhibitors of SGLT1 and SGLT2, as well as dual SGLT1/2 inhibitors. Since the approval of the first SGLT2 inhibitor in 2013 by the US Food and Drug Administration, SGLT2 inhibitors have become a new mainstay in the treatment of type 2 diabetes mellitus. They also have beneficial effects on the cardiovascular system (including heart failure) and the kidney. This review focuses on the rationale for the development of individual SGLT2 and SGLT1 inhibitors, as well as dual SGLT1/2 inhibition, including, but not limited to, aspects of genetics, genetically modified mouse models, mathematical modelling and general considerations of drug discovery in the field of metabolism.

Efficacy of DPP-4 inhibitors, GLP-1 analogues, and SGLT2 inhibitors as add-ons to metformin monotherapy in T2DM patients: a model-based meta-analysis.

Project description:AimsThe aim of the present study was to quantitate the hypoglycaemic effects of dipeptidyl peptidase-4 inhibitors (DPP-4i), glucagon-like peptide-1 receptor agonists (GLP-1r) and sodium glucose cotransporter 2 inhibitors (SGLT2i) as add-on treatments to metformin monotherapy in patients with type 2 diabetes mellitus (T2DM) using a model-based meta-analysis (MBMA).MethodsA systematic literature search of public databases was conducted to develop models that describe the time courses of the fasting plasma glucose (FPG)- and haemoglobin A1c (HbA1c)-lowering effects of three antidiabetic classes using NONMEM 7.3.0.ResultsSeventy-six publications were eligible for this study, and 873 FPG and 1086 HbA1c values were collected. We developed a physiological indirect response model that described the time courses of FPG and HbA1c and simulated reductions in these values 90 days after the initiation of add-on treatments. FPG and HbA1c reductions with once weekly exenatide, liraglutide and dulaglutide were greater than those with other drugs. Mean changes from baseline FPG and HbA1c with these drugs were as follows: exenatide (-22.5 and -16.6%), liraglutide (-22.1 and -16.3%), and dulaglutide (-19.3 and -14.3%). The hypoglycaemic effects of DPP-4i and SGLT2i were similar.ConclusionsOnce weekly exenatide, liraglutide and dulaglutide provided better hypoglycaemic effects among the antidiabetic drugs analysed. Long-acting GLP-1r appears to be more useful for T2DM patients inadequately controlled with metformin monotherapy.

CD73s protection of epithelial integrity: Thinking beyond the barrier.

Project description:The prevailing view of CD73 in cancer is that it is overexpressed in tumors and promotes cancer progression by dampening local T cell-mediated immune responses. We recently found that CD73 is down-regulated in poorly-differentiated and advanced stage endometrial carcinoma compared to normal endometrium and well-differentiated, early stage tumors. We revealed that CD73-generated adenosine induces a physiological response to protect epithelial integrity in well-differentiated, early stage endometrial carcinoma. The ability of CD73-generated adenosine to protect the barrier is not so different from its ability to induce immunosuppression and other physiological responses in cancerous tissues. In this commentary we examine the complexity of CD73 in cancer and suggest that a "one size fits all" approach to the role of CD73/adenosine in cancer is no longer warranted. Given that tumors often hijack normal cellular responses, we also provide consideration on how CD73s known role to protect barrier function may have implications in promoting tumor progression.

Is Extracellular Vesicle-Based Therapy the Next Answer for Cartilage Regeneration?

Project description:"Extracellular vesicles" (EVs) is a term gathering biological particles released from cells that act as messengers for cell-to-cell communication. Like cells, EVs have a membrane with a lipid bilayer, but unlike these latter, they have no nucleus and consequently cannot replicate. Several EV subtypes (e.g., exosomes, microvesicles) are described in the literature. However, the remaining lack of consensus on their specific markers prevents sometimes the full knowledge of their biogenesis pathway, causing the authors to focus on their biological effects and not their origins. EV signals depend on their cargo, which can be naturally sourced or altered (e.g., cell engineering). The ability for regeneration of adult articular cartilage is limited because this avascular tissue is partly made of chondrocytes with a poor proliferation rate and migration capacity. Mesenchymal stem cells (MSCs) had been extensively used in numerous in vitro and preclinical animal models for cartilage regeneration, and it has been demonstrated that their therapeutic effects are due to paracrine mechanisms involving EVs. Hence, using MSC-derived EVs as cell-free therapy tools has become a new therapeutic approach to improve regenerative medicine. EV-based therapy seems to show similar cartilage regenerative potential compared with stem cell transplantation without the associated hindrances (e.g., chromosomal aberrations, immunogenicity). The aim of this short review is to take stock of occurring EV-based treatments for cartilage regeneration according to their healing effects. The article focuses on cartilage regeneration through various sources used to isolate EVs (mature or stem cells among others) and beneficial effects depending on cargos produced from natural or tuned EVs.

Comparison of incident hypertension between SGLT2 inhibitors vs. DPP4 inhibitors.

Project description:Although several randomized clinical trials have reported the potential benefit of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in reducing blood pressure (BP), whether SGLT2i can reduce incident hypertension is unknown. We analyzed individuals with diabetes who were newly prescribed SGLT2i or dipeptidyl peptidase 4 inhibitors (DPP4i) in a large-scale epidemiological database. The primary outcome was the incidence of hypertension. A propensity score matching algorithm was employed to compare the subsequent development of hypertension between the SGLT2i and DPP4i groups. After propensity score matching, 5708 well-balanced pairs of SGLT2i and DPP4i users were identified. SGLT2i administration was associated with a reduced risk of hypertension (HR 0.91, 95% CI: 0.84-0.97). The advantage of SGLT2i use over DPP4i use for incident hypertension was generally consistent in several sensitivity analyses, and subgroup analyses showed that SGLT2i use was significantly associated with a lower risk of hypertension in men, patients with baseline HbA1c of <7.5%, and baseline systolic blood pressure ≥127 mmHg. Our investigation using nationwide real-world data demonstrated the potential advantage of SGLT2i over DPP4i in reducing the development of hypertension in individuals with diabetes.
