Question 1

What is the Meaning of SUSTAIN-6 Trial?

Accepted Answer

The SUSTAIN-6 trial represents a pivotal cardiovascular outcomes study for semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, investigating its effects on cardiovascular events in individuals diagnosed with type 2 diabetes. This randomized, double-blind, placebo-controlled trial provided essential data regarding semaglutide's safety and efficacy beyond its glucose-lowering capabilities.

Question 2

What is the Context of SUSTAIN-6 Trial?

Accepted Answer

Within the landscape of metabolic and cardiovascular health, the SUSTAIN-6 trial positioned semaglutide as an agent influencing not only glycemic control but also broader cardiometabolic parameters. Its findings are relevant for patients with type 2 diabetes who present with established cardiovascular disease or significant cardiovascular risk factors, addressing a critical need for therapies that mitigate cardiovascular morbidity and mortality.

Question 3

What is the Significance of SUSTAIN-6 Trial?

Accepted Answer

The trial's results significantly impacted clinical practice guidelines for type 2 diabetes management, particularly by demonstrating a reduction in major adverse cardiovascular events (MACE) with semaglutide. This outcome underscored the importance of selecting antidiabetic agents that offer cardiovascular protection, shifting therapeutic focus from sole glycemic management to a comprehensive approach to patient well-being.

Question 4

What is the Mechanism of SUSTAIN-6 Trial?

Accepted Answer

Semaglutide functions by activating GLP-1 receptors, distributed across various tissues including pancreatic beta cells, the gastrointestinal tract, and the central nervous system. This activation leads to glucose-dependent insulin secretion, suppression of glucagon release, delayed gastric emptying, and appetite reduction, contributing to improved glycemic control and weight loss. Cardiovascular benefits are attributed to these metabolic improvements and potential direct vascular protective effects.

Question 5

What is the Application of SUSTAIN-6 Trial?

Accepted Answer

The clinical application of findings from the SUSTAIN-6 trial encourages the use of semaglutide in adults with type 2 diabetes, especially those with pre-existing cardiovascular disease, to reduce cardiovascular event risk. Physicians now consider GLP-1 receptor agonists like semaglutide as a preferred option for such high-risk patients, often with other standard therapies and lifestyle modifications to optimize health outcomes.

Question 6

What is the Metric of SUSTAIN-6 Trial?

Accepted Answer

Key metrics assessed in the SUSTAIN-6 trial included the primary composite endpoint of MACE, defined as cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke. Additionally, researchers monitored changes in hemoglobin A1c (HbA1c) levels, body weight, blood pressure, and lipid profiles. The trial also collected data on adverse events to evaluate the overall safety profile of semaglutide.

Question 7

What is the Risk of SUSTAIN-6 Trial?

Accepted Answer

While generally well-tolerated, semaglutide, like other GLP-1 receptor agonists, carries certain risks. Common adverse effects involve the gastrointestinal system, including nausea, vomiting, diarrhea, and constipation, especially during treatment initiation. Documented risks include pancreatitis and cholelithiasis. A theoretical concern regarding thyroid C-cell tumors, observed in rodent studies, necessitates careful consideration in patients with a history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2.
