Semaglutide, the energetic ingredient in Ozempic, and different medicine in the identical class have revolutionized the therapy of weight problems and kind 2 diabetes. Now, a medical trial suggests the medicines can deal with sort 1 diabetes, as nicely.
The trial outcomes, printed June 23 within the journal NEJM Proof, counsel semaglutide can enhance blood sugar ranges and induce weight reduction in individuals with sort 1, probably introducing a brand new drug that could possibly be used together with insulin to handle the illness.
“For 100 years, we’re fixated on insulin and insulin supply … and there aren’t actually additional medicines which are permitted for sort 1,” lead research creator Dr. Viral Shah, a diabetes researcher at Indiana College, advised Reside Science. There are some add-on medicine permitted to be used alongside insulin, however Shah envisions Ozempic-like medicine as a possible firstline therapy.
The insulin resistance and impaired launch of digestive hormones that gasoline sort 2 diabetes also can exist in sort 1, so it does make sense to discover therapies for these, he stated.
Kind 1, sort 2, and double diabetes
Kind 1 and kind 2 diabetes are pushed by very completely different mechanisms.
In sort 2, cells within the pancreas that make insulin grow to be much less delicate to blood sugar and produce much less insulin in response. Insulin usually helps usher sugar from the bloodstream into cells, so this impact causes sugar to construct up within the blood. In the meantime, sort 1 diabetes is an autoimmune dysfunction during which the insulin-secreting cells are destroyed by one’s personal immune system.

There are a number of medicine for sort 2 diabetes that target driving cells to secrete extra insulin, and there are customary therapies centered round enhancing blood sugar management, weight reduction, hypertension and heart problems danger by life-style modifications. Medicine like semaglutide, generally known as GLP-1 agonists, management blood sugar in sort 2 by lowering a liver-made hormone that raises blood sugar, in addition to slowing down digestion. This makes you are feeling fuller for longer and permits the pancreas extra time to launch the correct amount of insulin.
The first method to management blood sugar in sort 1 diabetes, nonetheless, is insulin alternative. However sort 1 diabetics, particularly these with weight problems, usually have insulin resistance and thus most of the identical well being points as these with sort 2 — for instance, nerve injury, foot ulcers and eye injury, all on account of uncontrolled blood sugar. This situation has been termed “double diabetes.”
“Kind 1 diabetes doesn’t exclude the presence of sort 2 diabetes,” Shah stated. “Individuals with the double diabetes phenotype could profit from a few of the medicines which are presently permitted for sort 2 diabetes.” That was the thought behind the brand new trial of semaglutide, the ingredient discovered within the weight-loss drug Ozempic and kind 2 diabetes drug Wegovy.
The researchers recruited 72 sufferers with sort 1 diabetes and weight problems, based mostly on their BMIs. Half the members acquired a weekly semaglutide injection and the opposite half a placebo for 26 weeks. All of the members continued utilizing insulin as wanted all through the trial, and their blood sugar was monitored utilizing steady glucose screens.
The sufferers taking semaglutide had higher management over their blood sugar ranges, staying inside an appropriate vary of blood sugar ranges over 70% of the time whereas additionally spending much less time with low blood sugar ranges. The handled people additionally misplaced no less than 5% of their physique weight. However nobody within the untreated group met all three of those standards.
These outcomes help findings from different current trials, exhibiting that these medicine used for sort 2 diabetes are value exploring in sort 1 diabetics, stated Ahmad Haidar, a diabetes researcher at McGill College in Canada, who was not concerned within the research.
“It is an vital research that provides to the present proof towards the protection and efficacy of the usage of semaglutide in sort 1, however it’s not sufficient,” Haidar advised Reside Science. “We’d like extra proof to assist these medicine be permitted by regulatory businesses.”
Shah and his colleagues hope that with extra medical trials with greater cohorts of sufferers, the analysis group will collect sufficient proof to have this use of GLP-1s permitted by the Meals and Drug Administration and added into the American Diabetes Affiliation requirements of take care of sort 1. If permitted, the therapies might then probably be lined by medical health insurance.
“And if that occurs, I feel this is able to be in all probability the primary drug past insulin for individuals with sort 1 diabetes to make use of,” Shah stated. “It is actually thrilling that it is transferring ahead.”
