A new form of weekly insulin can control type 1 and type 2 diabetes as well as daily injections
The weekly shot involves a new class of insulin called efsitora
Such shots would allow for easier control of blood sugar than daily jabs, researchers say
Weekly insulin shots can help control both type 1 and type 2 diabetes as well as daily injections do, a pair of clinical trials have found.
A new class of insulin called efsitora alfa has been designed to require injections only once a week, researchers said.
Two phase 3 trials presented Tuesday at the European Association for the Study of Diabetes annual meeting in Madrid show that efsitora is as safe and effective as standard daily insulin shots:
One trial in 928 people with type 2 diabetes found that weekly efsitora controlled blood sugar levels as well as a long-acting form of insulin called degludec.
The other trial found that once-weekly efsitora also performed as well as daily degludec in 623 people with type 1 diabetes.
“A once-weekly insulin has the potential to simplify dose administration and diminish barriers to starting insulin therapy by means of a reduction in injection burden as compared with a once-daily insulin,” wrote the team behind the type 2 diabetes trial, which was led by Dr. Carol Wysham, an endocrinologist with the MultiCare Rockwood Center for Diabetes and Endocrinology in Spokane, Wash.
"Traditionally, basal insulins are dosed once a day -- a treatment schedule that can make compliance difficult for a significant portion of people living with type 2 diabetes," said Wysham said in a news release from drug maker Eli Lily. "Efsitora has the potential to address treatment burden and improve adherence -- all while lowering A1C. These results can make a significant impact for people living with type 2 diabetes looking for a once-weekly option that provides similar outcomes as daily insulins."
In both clinical trials, which lasted 52 weeks, researchers randomly assigned participants to taking either efsitora or degludec insulin.
The major difference in the results between the two trials involved hypoglycemic (low blood sugar) events.
The type 2 diabetes trial found no statistically significant difference between efsitora and degludec when it came to hypoglycemia.
But hypoglycemia occurred more often for type 1 diabetics taking efsitora (10%) compared with degludec (3%), results show.
More work is needed to figure out the best dose “to maintain efficacy while mitigating the risk of hypoglycemia with weekly efsitora treatment in people with type 1 diabetes,” concluded the type 1 diabetes trial team led by Dr. Richard Bergenstal, executive director of the HealthPartners Institute's International Diabetes Center in Minneapolis.
"People with type 1 diabetes need insulin every day. Currently, they can deliver the insulin using an automated insulin delivery system or by taking a daily basal insulin injection and multiple mealtime insulin injections each day," Bergenstal explained in an Eli Lilly news release. "This new data shows that with one dose a week of basal insulin, efsitora was able to achieve a similar A1C reduction as taking an injection of one of the most used background insulins every day. I look forward to further evaluation of these data, including ways to minimize hypoglycemia, so once-weekly insulin can be one option for personalizing the management of type 1 diabetes."
The type 2 diabetes trial also found that efsitora worked well in diabetics even if they were taking a GLP-1 drug like Ozempic.
“Given treatment guidelines and recommendations to incorporate GLP-1 receptor agonists earlier in treatment, along with their growing use worldwide, it is relevant to show that efsitora can be effectively and safely added to such therapy,” Wysham’s team concluded in a meeting news release.
Type 1 diabetes is an inherited condition in which the immune system destroys or damages the body’s ability to make insulin. People with type 2 diabetes develop resistance to insulin, which also can destroy or damage the ability to make insulin.
Results from the type 2 diabetes trial were published Sept. 10 in the New England Journal of Medicine, while results from the type 1 trial were published Sept. 10 in The Lancet.
