(Reuters) – Novo Nordisk’s blockbuster diabetes drug Ozempic and weight-loss therapy Wegovy are being studied to see whether they can improve health in other ways.
Both treatments contain the active ingredient semaglutide, part of a class known as GLP-1 drugs that work by helping control blood sugar levels and triggering a feeling of fullness.
New data suggests that semaglutide may also cut the risk of stroke or heart attack, and may delay the progression of kidney disease in diabetes patients.
Below are other conditions that GLP-1 treatments are being tested against:
Chronic kidney disease
Eli Lilly’s tirzepatide, a GLP-1 therapy sold as Mounjaro for diabetes and Zepbound for weight loss, is being evaluated in a mid-stage study of chronic kidney disease in patients with obesity. Lilly plans to enroll up to 140 participants.
Cardiovascular disease
Lilly is also testing tirzepatide for patients with heart failure and obesity. Lilly expects to enroll about 700 people in the study, which is expected to be completed by July 2024.
Researchers at the Chinese University of Hong Kong are testing Novo’s semaglutide along with mechanical removal of clots in patients with strokes caused by the blockage of large blood vessels to the brain compared with standard therapy. The mid-stage study aims to recruit about 140 patients.
Neurological disorders
Researchers at the Danish Headache Center, Denmark, are testing semaglutide as a treatment for new-onset Idiopathic Intracranial Hypertension, a condition associated with obesity where pressure inside the head rises, along with a very low calorie diet. The study aims to recruit about 50 patients and wrap up as early as 2025.
Alzheimer’s disease
Novo has begun a trial testing semaglutide in patients with early Alzheimer’s disease. The study, which will enroll 1,840 patients, could reach primary completion as early as 2025.
Liver disease
Novo is testing semaglutide in a late-stage trial of patients with a type of fatty liver disease called non-alcoholic steatohepatitis (NASH). The study is expected to enroll about 1,200 patients and close as early as 2028.
Lilly’s tirzepatide is also being evaluated in a mid-stage study in nearly 200 NASH patients.
Parkinson’s disease
Researchers at University Hospital, Toulouse, France tested Sanofi SA’s GLP-1 drug lixisenatide, branded as Adlyxin for the treatment of type 2 diabetes, in addition to usual anti-Parkinson’s drugs in a mid-stage study of about 156 patients with early Parkinson’s disease.
Preliminary results showed the therapy might slow progression of motor symptoms, with more data expected in early 2024.
Sleep apnea
Lilly’s tirzepatide is in late-stage testing for treatment of patients with obstructive sleep apnea and obesity, including people who use respiratory devices that help keep their airways open while they sleep as well as people who won’t use such devices. The study is expected to enroll about 469 participants.
In a pilot study sponsored by Cincinnati Children’s Hospital, researchers found that Novo’s GLP-1 drug Victoza, or liraglutide, helped reduce the severity of sleep apnea in 12 out of 18 adult patients without diabetes.
Polycystic Ovary Syndrome (PCOS)
Researchers at the Women’s Hospital in Los Angeles found that liraglutide, the active ingredient in Novo’s drugs Victoza and Saxenda, helped reduce elevated testosterone levels significantly in obese women with polycystic ovary syndrome, the most common hormonal disorder in females of reproductive age. The late-stage study enrolled 88 participants.
Knee Osteoarthritis
An experimental Lilly GLP-1, retatrutide, is being studied in patients who are overweight and have osteoarthritis of the knee, a degenerative joint disease. The study is currently enrolling up to 405 patients.
Alcohol Addiction
A study by the University of Copenhagen’s Psychiatric Centre Rigshospitalet is investigating whether treatment with semaglutide helps reduce alcohol intake in 108 patients diagnosed with alcohol use disorder and obesity.
