Emerging Therapies in Diabetes: What’s Next Beyond Oral Drugs

While oral diabetes drugs remain the foundation of diabetic therapy, they often fail to control blood glucose levels or address the underlying cause of the disease. The new era of emerging diabetes therapies goes beyond traditional oral diabetes medications and offers an all-new hope for millions worldwide. This article covers various aspects of diabetes, including epidemiology and new diabetes treatment, highlighting what’s ahead beyond oral diabetes drugs.

Diabetes has become a significant public health issue affecting millions of people worldwide and has been rising dramatically across the globe. Importantly, type 2 diabetes is the commonest type and accounts for over 96% of all diabetes cases. Diabetes is a serious metabolic disorder characterised by insulin resistance and impaired pancreatic beta-cell function, ultimately leading to increased blood glucose levels. It is a long-term condition that increases the risk of developing various diseases by damaging small and large blood vessels.  Conventional therapies, including metformin, insulin, and sulfonylureas, have long served as the cornerstone of treatment. However, they often face limitations such as side effects, reduced effectiveness over time, and problems in achieving optimal sugar control.

Unless contraindicated or not tolerated, metformin, one of the commonly used oral diabetes drugs, is the first-line treatment in combination with diet and lifestyle. It acts by reducing liver glucose output and improving insulin resistance. It is considered weight-neutral and has a very low risk of hypoglycaemia (low blood sugar). Gastrointestinal side effects are common, and it is contraindicated because of the increased risk of acidosis in patients with renal, liver and cardiac insufficiency. Such issues have sparked considerable interest in developing novel, experimental therapeutic options or new diabetes medications to improve treatment outcomes. Despite these advancements, diabetes remains a major health challenge, and further research is needed to develop effective treatments and prevent its complications. Moreover, several new studies on diabetes are underway, and researchers are putting all their efforts into reaching the heights of diabetes discovery.

Latest Diabetes Discovery: Transformation from traditional advanced diabetes therapies

For decades, oral diabetes medications dominated the management of type 2 diabetes. These anti-diabetic medications are extremely effective in lowering blood glucose, but do not address the root causes of diabetes, such as insulin resistance, metabolic inflammation, and pancreatic dysfunction. Today’s research focuses on targeted, patient-centred treatment that goes beyond symptomatic relief to offer long-term metabolic balance. Interventions such as injectable biologics, gene-based therapies, and regenerative medicines point towards further advancements in diabetes care. These diabetic therapies are designed not only to control blood sugar but also to support proper organ function, restore natural insulin function and prevent complications associated with diabetes.

GLP-1 receptors:

Among the most revolutionary advancements in diabetes are GLP1-agonists. Glucagon-like peptide-1 (GLP-1) agonists are a class of medications that lower glucose levels and thereby improve glucose metabolism in patients with diabetes. GLP-1 is most often an injectable medication, which means you inject a liquid medicine with a needle and syringe. These shots are usually given in the fatty tissues just under your skin. You can find these fatty tissues in areas such as your belly, upper buttocks, outer thighs, and the backs of your arms. These are the new diabetes medications.

The most innovative development in diabetes care is the discovery of GLP-1 receptor agonists, such as semaglutide and liraglutide. These pharmaceutical agents mimic glucagon-like peptide-1 (GLP-1), a natural hormone that stimulates insulin secretion after meals, suppresses appetite, and slows gastric emptying. Currently, a new class of medications, Incretins and incretin-based therapy, has been introduced, combining GLP-1 (glucose-dependent insulinotropic polypeptide) and GIP (glucose-dependent insulinotropic polypeptide) receptor agonists. The first pharmaceutical agent in this newly introduced class of diabetes medication is tirzepatide, which has shown exceptional results in new studies in diabetes. Tirzepatide not only reduces blood sugar levels but also promotes significant weight loss. These new diabetes medications help manage diabetes and obesity by addressing both body weight and insulin resistance, which are key contributors to this metabolic condition.

SGLT2 inhibitors:

These include oral diabetes drugs like dapagliflozin and empagliflozin, which are not entirely new diabetes medications but continue to gain popularity due to their beneficial effects on renal and cardiovascular health. These medications were originally discovered to reduce blood sugar by increasing glucose excretion through urine. They are now identified for lowering the risk of heart failure, renal disease progression and even cardiovascular health.

Stem cell therapies:

The conventional approaches in the management of diabetes mellitus do not resolve the causes of the disease and are laden with side effects. Hence, the quest for a desirable difference in the therapeutic regimen is ongoing. The cellular-based therapeutic strategy is currently being utilised to treat pancreatic conditions, aiming to restore beta cell function and insulin secretion. The stem cell-based diabetes management therapy aims to replace malfunctioning or damaged pancreatic cells with pluripotent or multipotent stem cells. Advancements in technology have facilitated the development of stem cells from various tissue sources, including adipose tissue, bone marrow, periosteum, umbilical cord blood, and dental pulp.

DPP-4 inhibitors

The most novel drug classes, SGLT2 and GLP-1, have been demonstrated to cause a significant reduction in adverse cardiovascular outcomes and thus secure a prominent place in the therapeutic landscape of high blood sugar. In this context, the role of DPP4 inhibitors has been modified. DPP-4 inhibitors carry a favourable safety profile. These medications do not cause low blood sugar or weight gain, and do not require dose increments. In addition, they can be used in patients with chronic kidney impairment and elderly patients after dose adjustments. Still, they have been categorised as third-line treatment options, as they have not been demonstrated to lower cardiovascular events, unlike GLP-1 and SGLT2. Overall, these medications hold a position in diabetes therapy as a safe class of oral diabetes drugs with years of experience. DPP-4 inhibitors are oral medications used to treat type 2 diabetes by increasing insulin levels and lowering blood sugar levels. These drugs work by blocking the DPP-4 enzyme, which allows incretin hormones like GLP-1 to remain active. Examples include oral diabetes medications such as sitagliptin, saxagliptin, linagliptin, and alogliptin, which are taken alongside diet and exercise.

Despite not decreasing the teh risk of cardiovascular problems, these medications have a position in the diabetes treatment list for several patients.

Gene therapy:

This latest diabetes discovery aims to alter the defective genes that regulate glucose or beta cell function. Certain techniques are being researched and tested to correct genetic mutations that give rise to the development of diabetes.

These new diabetes medications have the potential to shift diabetes management from lifelong medication to disease reversal.

Summary

Diabetes is a serious health issue that contributes to progressive dysregulation. The diabetes care management is changing than ever before. While oral diabetes medications continue to play a crucial role, the focus is shifting towards advanced strategies, smart technologies and treatment options that aim not only to control but potentially cure diabetes mellitus. Recent advances in diabetes management feature Peptides such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide. These have been explored as a potential treatment for diabetes. The technologies mentioned above bring us closer to a world where living with diabetes no longer means living with imitations and fear.
