Major Breakthrough in Weight Loss With Semaglutide? (medscape.com)
In a phase 3 trial where all participants received intensive behavior therapy, investigational 2.4-mg once-weekly subcutaneous semaglutide (Novo Nordisk) resulted in a 10.3% greater average weight loss than placebo over a period of 68 weeks.
If approved, this medication could be a "potential major breakthrough" in obesity management, the investigators suggest. But other experts urge caution, as cost and uptake are important considerations.
Perhaps even more impressive was the finding that 75% of patients lost 10% or more of baseline body weight," said Wadden, of the Department of Psychiatry, Perelman School of Medicine, University of Pennsylvania.
Moreover, in this trial of semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist that is approved for treating type 2 diabetes at a weekly subcutaneous dose of 1 mg (Ozempic, Novo Nordisk), but is being investigated at the higher dose for weight loss — 55% of patients lost ≥ 15% of their initial weight, and 36% lost ≥ 20% of their initial weight. ….
In the discussion that followed the virtual presentation, one attendee asked about potential weight regain if a patient stopped taking the drug. Based on experience with another subcutaneous injectable GLP-1 receptor agonist, liraglutide (Saxenda, Novo Nordisk), already approved for obesity, it may be that taking medicine for chronic overweight may become like taking a statin for elevated cholesterol, said Wadden.
Novo Nordisk has now completed the four trials in the STEP (Semaglutide Treatment Effect in People With Obesity) global phase 3 clinical development program, and plans to file applications with the US Food and Drug Administration (FDA) later this year and with the European Medicines Agency in early 2021 for review of semaglutide 2.4 mg for weight management. ….
During the first 8 weeks, participants were provided with a 1000-1200 kcal/day meal replacement diet that included liquid shakes, meal bars, and prepared entrees designed to facilitate a large initial weight loss.
They then transitioned to a diet of conventional foods (of their choosing), with a goal of 1200-1800 kcal/day based on body weight.
The physical activity goal was 100 minutes/week of walking or other aerobic activity in the first month, building up to 200 minutes/week by month 6. …
As well as being approved as a weekly subcutaneous injectable treatment for type 2 diabetes, semaglutide is also approved as an once-daily oral agent for the same indication (Rybelsus, Novo Nordisk) in doses of 7 mg and 14 mg to improve glycemic control along with diet and exercise. It is the first GLP-1 agonist available in tablet form.
