The Journey and Excitement Following the Development of the First Peptide in a Pill: A Brief Overview of Pharmacology and Clinical Trials of Oral Semaglutide
Oral semaglutide is the newest discovery, the first in class peptide in a pill. Sodium N-(8-[2-hydroxybenzoyl]amino)caprylate (SNAC), a small fatty acid, has been co-formulated with semaglutide, which facilitates its absorption from the gastric mucosa. It has 94% homology with human glucagon-like peptide 1 (GLP-1). It comes in three dose forms – 3 mg, 7 mg and 14 mg. It is given as once daily dosing and is recommended in adult type 2 diabetes mellitus patients as monotherapy when metformin is contraindicated or not tolerated and in combination with other oral antidiabetic drugs (OADs). In a phase 3 trial, it has been shown to reduce glycated hemoglobin (HbA1c) up to 1.5%, with weight reduction up to 5 kg with a 14 mg dose. There was nonsignificant risk reduction of 21% in 3-point major adverse cardiovascular events (MACE) and 51% and 49% risk reduction in cardiovascular (CV) deaths and all-cause mortality, respectively. Oral semaglutide was found to be superior to empagliflozin, sitagliptin and liraglutide in both glycemic control and weight reduction. It also exhibits many pleiotropic effects – reduced energy intake, anti-inflammatory and anti-atherosclerotic effect, to name a few. Nausea was the most common side effect which was experienced by only 15% to 20% of patients. It was mild-to-moderate and transient. Overall, oral semaglutide has shown its efficacy both early and late in the management of diabetes, irrespective of renal and hepatic impairment
Approach to a Newly Diagnosed Adult with Type 2 Diabetes in the Indian Context: Recommendations by Association of Clinical Endocrinologists Consensus Group
SGLT-2 inhibitors in development for type 2 diabetes treatment.
The prevalence of type 2 diabetes is increasing worldwide. The majority of currently available glucose-lowering agents work via insulin-dependent mechanisms and have significant limitations. Hence, there is a need for newer treatments utilizing novel therapeutic targets. Drugs which inhibit the sodium glucose cotransporter in the renal tubules (SGLT-2 inhibitors), represent a novel class of drugs under development. By inhibiting SGLT-2, they promote increased renal glucose excretion and thereby calorie loss with improved glycemic control and weight loss. Dapagliflozin is most advanced in development of this new drug class and currently undergoing phase 3 trials. In addition to its glucose lowering effect, dapagliflozin appears to have favorable impacts on weight and blood pressure, with low risk of hypoglycemia. However, as with all new treatments, long-term safety is an issue. Clinical trials showed increased risk of genital and possibly urinary infections with dapgliflozin. Furthermore, concerns have arisen regarding a possible increased incidence of breast and bladder cancer in patients on dapagliflozin. However, it needs further investigation to confirm or refute whether these concerns are concrete
Effect of fibrate treatment on liver function tests in patients with the metabolic syndrome.
BACKGROUND
Fibrates are used especially in patients with hypertriglyceridaemia, a feature of the metabolic syndrome. Elevated LFTs are often observed in these patients perhaps related to fatty infiltration.
AIM
We wished to study changes seen in LFTs (GGT, ALT and ALP) following fibrate therapy and then determine associated factors.
METHODS
This was a retrospective observational study in which data was collected from case notes of patients started on fibrates (n = 118, 2002-2008) in the lipid clinic at Good Hope Hospital and pre/post-fibrate lipid and LFT values were obtained. All biochemistry was performed on the Roche P-Unit using supplied reagents. Statistical analyses included t tests and regression analyses (factorised when quartiles were compared).
RESULTS
Of the study population 106 patients were on fenofibrate; the remaining on bezafibrate. Significant lowering of GGT (p  57 IU/l, ALT > 34 IU/l and ALP > 94 IU/l) significantly different to the lowest quartile. The above associations remained significant even when the regression analyses were corrected for changes in lipid values (which did not show an association).
CONCLUSIONS
Fibrate treatment led to improvements in LFT, the greatest benefit seen in patients with higher baseline LFT values. It appears that baseline and changes in lipid values post fibrate treatment were not associated with change in LFT
Testosterone replacement therapy with long-acting testosterone undecanoate improves sexual function and quality-of-life parameters vs. placebo in a population of men with type 2 diabetes.
INTRODUCTION
Sexual dysfunction, particularly erectile dysfunction (ED), is common in men with type 2 diabetes, occurring in up to 75% of cases. The prevalence of hypogonadism is also high in men with diabetes and low testosterone is associated with both sexual dysfunction and a reduced response to oral therapy for ED.
AIM
This study aimed to determine the effect of testosterone replacement with long-acting Testosterone Undecanoate (TU) on sexual function, mood and quality of life vs. placebo over a treatment period of 30 weeks followed by 52 weeks of open-label medication. The study was conducted in a primary care population of men with type 2 diabetes attending their primary care physician for routine visits.
METHODS
The male diabetic populations of seven general practices were screened at routine diabetes visits to detect symptomatic men with total testosterone levels of 12 nmol/L or less or with free testosterones of 250 pmol/L or less. Two hundred eleven men were screened. A double-blind placebo-controlled study was conducted in 199 men with type 2 diabetes and hypogonadism treated for 30 weeks with either 1,000 mg of TU or matching placebo followed by 52-week open-label follow on.
MAIN OUTCOME MEASURES
The primary outcome measure, International Index of Erectile Function (IIEF), was used to evaluate sexual dysfunction, and the Ageing Male Symptom (AMS), Hospital Anxiety and Depression Scale, and Global Efficacy Question were used as secondary outcome measures to assess mood and self-reported quality of life.
RESULTS
Testosterone replacement therapy with long-acting TU improved all domains of sexual function at 30 weeks (erectile function [EF], P = 0.005; intercourse satisfaction, P = 0.015; sexual desire, P = 0.001; overall satisfaction, P = 0.05; and orgasm, P = 0.04), with benefit as early as 6 weeks. Improvements in AMS score were significant in men without depression (P = 0.02) and the presence of depression at baseline was associated with marked reduction in response to both sexual function and psychological scores. All responses in sexual function continued to improve significantly up to 18 months with an improvement in EF score of 4.31 from baseline. In a small cohort of 35 men taking phosphodiesterase type 5 inhibitors, there was no change during the double-blind phase but a nine-point improvement in EF domain during 52-week open-label treatment. After 30 weeks, 46% vs. 17% of patients on active therapy vs. placebo felt that the treatment had improved their health, reaching 70% after open-label therapy. Less obese and older patients responded better to testosterone therapy. There were no significant adverse events.
CONCLUSION
TU significantly improved all domains of the IIEF and patient reported quality of life at 30 weeks and more significantly after 52-week open-label extension. Improvement was most marked in less obese patient and those without coexisting depression. In men with type 2 diabetes, trials of therapy may need to be given for much longer than 3-6 months suggested in current guidelines
Testosterone replacement therapy improves metabolic parameters in hypogonadal men with type 2 diabetes but not in men with coexisting depression: the BLAST study.
INTRODUCTION
The association between testosterone deficiency and insulin resistance in men with type 2 diabetes is well established and current endocrine society guidelines recommend the measurement of testosterone levels in all men with type 2 diabetes or erectile dysfunction.
AIM
We report the first double-blind, placebo-controlled study conducted exclusively in a male type 2 diabetes population to assess metabolic changes with long-acting testosterone undecanoate (TU).
METHODS
The type 2 diabetes registers of seven general practices identified 211 patients for a 30-week double-blind, placebo-controlled study of long-acting TU 1,000 mg followed by 52 weeks of open-label use. Because of the established impact of age, obesity, and depression on sexual function, these variables were also assessed for influence on metabolic parameters.
MAIN OUTCOME MEASURE
Changes in glycated hemoglobin (HbA1c) and the level of testosterone at which response are achieved.
RESULTS
Treatment with TU produced a statistically significant reduction in HbA1c at 6 and 18 weeks and after a further 52 weeks of open-label medication most marked in poorly controlled patients with baseline HbA1c greater than 7.5 where the reduction was 0.41% within 6 weeks, and a further 0.46% after 52 weeks of open-label use. There was significant reduction in waist circumference, weight, and body mass index in men without depression, and improvements were related to achieving adequate serum levels of testosterone. There were no significant safety issues.
CONCLUSIONS
Testosterone replacement therapy significantly improved HbA1c, total cholesterol, and waist circumference in men with type 2 diabetes. Improvements were less marked in men with depression at baseline, and therapeutic responses were related to achieving adequate serum testosterone levels. Current advice on 3- to 6-month trials of therapy may be insufficient to achieve maximal response. Patients reported significant improvements in general health
