Half of GLP-1 Users Stop Within a Year

About half of the people who start a GLP-1 stop within a year. In Prime Therapeutics' US data on people taking one for obesity, only 1 in 12 were still on it at three years. I think those numbers should get far more attention than they do. Right now most of it goes to whichever new drug comes next. Preventing churn in the UK GLP-1 market is like trying to grab a fistful of water. The drug has become a commodity, so patients see providers as interchangeable and move on price. Patients pay for it as well. In the STEP 1 extension, people regained about two thirds of the weight they had lost within a year of stopping. SELECT, the trial people point to when they call these drugs longevity drugs, followed people with heart disease for over three years. Most people in the real world stop long before that. Does GLP-1 still works as a geroprotector when someone only takes it for six months? I do not know. The first thing I'd want to find out is who is still taking it in year three. How long do your patients actually stay on?
