Novo Nordisk's CagriSema: A Game Changer in Cardiovascular Health

In the evolving landscape of obesity treatment, Novo Nordisk's CagriSema has emerged as a notable player, showing promising results at the recent ObesityWeek® 2025 held in Atlanta, GA. New findings from the phase 3 REDEFINE 1 trial highlighted its potential not just in managing weight, but in fundamentally improving cardiovascular health by significantly lowering blood pressure and reducing inflammation markers.

Understanding CagriSema

CagriSema is a combination medication that pairs the amylin analogue, cagrilintide, with the GLP-1 receptor agonist, semaglutide. This innovative formulation works by enhancing the body’s ability to control blood sugar levels and manage appetite, thus supporting weight loss initiatives for patients struggling with obesity or overweight conditions.

Key Findings — A Closer Look

A detailed analysis from the REDEFINE 1 trial revealed that participants on CagriSema experienced a remarkable reduction in systolic blood pressure, averaging 10.9 mmHg over 68 weeks. This was in contrast to those treated with semaglutide alone or a placebo, who showed lesser reductions (8.8 mmHg and 2.1 mmHg, respectively). Notably, around 40% of the subjects on blood pressure medications found they could either reduce or completely stop their medication while on CagriSema treatment.

Moreover, CagriSema had a striking impact on inflammatory markers, specifically a 68.9% reduction in high-sensitivity C-reactive protein (hsCRP), surpassing reductions seen with semaglutide alone and placebo. This suggests that the anti-inflammatory effects of CagriSema contribute to its overall efficacy.

Implications on Cardiovascular Health

With cardiovascular disease being a leading cause of morbidity and mortality globally, the results of CagriSema’s trial are particularly timely. High blood pressure and systemic inflammation are prominent risk factors for atherosclerotic cardiovascular disease (ASCVD). The findings indicated that fewer patients treated with CagriSema fell into the intermediate-to-high risk category for developing ASCVD within the next decade.

Professor Subodh Verma, a cardiac surgeon from the University of Toronto, emphasized the importance of these findings, stating that the ability of CagriSema to lower inflammation and bring blood pressure levels in check could lead to significant improvements in overall health for individuals battling obesity.

Safety Profile and Future Directions

The safety profile of CagriSema in the trial echoed that of its counterparts in the GLP-1 receptor agonist family, with low discontinuation rates due to adverse effects. Most reported side effects were gastrointestinal, including nausea and constipation, yet they were generally transient and manageable.

Novo Nordisk’s commitment to informing the development of further cardiovascular-focused trials continues, with ongoing studies like REDEFINE 3 set to explore CagriSema's effects on patients with pre-existing cardiovascular conditions, with or without type 2 diabetes. The goal remains to provide a holistic approach to weight management that encompasses not only weight loss but also the mitigation of associated health risks.

The Bigger Picture: Obesity Management

Obesity is a complex condition that necessitates comprehensive treatment strategies. The stigma often associated with obesity overlooks the biological and environmental factors contributing to this chronic disease. CagriSema represents hope in a new armamentarium of treatments designed to tackle both weight loss and prevent obesity-related complications, particularly cardiovascular diseases.

Novo Nordisk's historical legacy in diabetes care positions it well to influence the future landscape of obesity management, creating pathways for patients looking for effective therapies. As CagriSema awaits approval in the US and EU, its promising results could redefine standards of care for obesity treatment, aligning patient-centered outcomes with successful weight management and cardiovascular risk reduction.
