The potential health benefits of GLP-1 (glucagon-like peptide-1) drugs, known for their use in weight loss and diabetes management, are expanding. Novo Nordisk recently revealed that its GLP-1 drug liraglutide may slow Alzheimer’s disease progression by protecting the brain, according to new mid-stage trial data. Additionally, another study indicated that semaglutide, found in Novo Nordisk’s Wegovy and Ozempic, could aid smoking cessation. These GLP-1 treatments mimic gut hormones to suppress appetite and regulate blood sugar, and researchers believe they might also reduce inflammation and treat other conditions.
However, more extensive research and longer trials are necessary before regulators can approve these drugs for additional uses. The FDA took a significant step in March by approving Wegovy to reduce the risk of serious heart complications. This could increase pressure on insurers to cover these treatments, which often cost around $1,000 per month. Here are other conditions GLP-1s are being tested for:
1. Cardiovascular Health:
• Wegovy has been shown to reduce the risk of heart attack, stroke, and death from cardiovascular causes by 20% in obese patients with heart disease.
• It also alleviated cardiovascular symptoms in patients with obesity, diabetes, and heart failure.
• Eli Lilly’s tirzepatide (in Zepbound and Mounjaro) is being tested in a late-stage trial for obesity and heart failure, expected to conclude this month.
2. Chronic Kidney Disease:
• Novo Nordisk’s Ozempic slowed chronic kidney disease progression in diabetes patients, reducing the risk of death and major cardiac events by 24%.
• Eli Lilly is also studying tirzepatide for obesity and chronic kidney disease in a trial ending in 2026.
3. Fatty Liver Disease:
• Eli Lilly’s Zepbound significantly improved fatty liver disease outcomes in a mid-stage trial.
• Novo Nordisk and other companies like Zealand Pharma, Viking Therapeutics, and Altimmune are also studying GLP-1 treatments for fatty liver disease.
4. Sleep Apnea:
• Zepbound has shown promise in resolving moderate to severe obstructive sleep apnea, and the FDA is reviewing it for this use.
5. Alzheimer’s Disease:
• Novo Nordisk is investigating semaglutide in late-stage trials for Alzheimer’s disease.
6. Addiction:
• Studies are exploring GLP-1s’ potential to curb addictive behaviors, including nicotine and alcohol use. Novo Nordisk is planning a study to see if semaglutide can reduce alcohol consumption.
The broadening scope of GLP-1 applications underscores their potential as versatile treatments for various conditions beyond weight loss and diabetes.
