The full results on Lilly’s tirzepatide for obesity will likely dominate the headlines from the annual scientific sessions of the American Diabetes Association, but the conference program is jam-packed with new findings – and new paradigms – in both type 1 and type 2 diabetes management and prevention.
Taking place June 3-7 both in person – for the first time in 3 years – in New Orleans, and virtually, the “hybrid” meeting is mandating COVID-19 vaccination and mask wearing for all on-site attendees.
A major topic will be new findings and thinking in the treatment of type 2 diabetes, including the new twincretin tirzepatide, as well as discussions about the role of weight loss and the concept of “remission.” In type 1 diabetes, sessions will examine intervention trials to prevent progression, progress in islet transplantation, and the latest findings in diabetes technology.
Other key conference themes include the often interrelated topics of disparities, mental health, and COVID-19.
“I think that the scientific planning committee has put together a really outstanding program this year, covering the entire spectrum of diabetes care and research and translation for both type 1 and type 2 diabetes,” Scientific Planning Committee Chair Dana Dabelea, MD, PhD, professor of epidemiology and pediatrics at the University of Colorado Anschutz Medical Campus, Aurora, told this news organization.
Tirzepatide: The next big thing?
The presentation likely to generate the most buzz will take place Saturday morning, with the full detailed results from Lilly’s phase 3 SURMOUNT-1 trial of its dual-incretin tirzepatide for weight loss in people with obesity or overweight with at least one comorbidity but not diabetes.
Top-line results released by Lilly in April 2022 showed that the drug induced weight loss of up to 22%. Tirzepatide was approved May 13 by the Food and Drug Administration for type 2 diabetes under the brand name Mounjaro. It is not approved for weight loss.
“Certainly the general public will latch on to this idea that there is a drug they can lose 22% of their weight on,” Robert A. Gabbay, MD, PhD, ADA chief science and medical officer, told this news organization. “It’s hard to comment on a press release, so that’s why this presentation is going to be key.”
Another tirzepatide analysis, this one comparing its use to insulin glargine on kidney outcomes in participants with diabetes in the pivotal SURPASS-4 study, will be presented as an ADA Presidents’ Select Abstract on Friday afternoon.
“I think tirzepatide could be the great new thing, but I think we need to know a little bit more. Weight loss seems to be better than with glucagon-like peptide-1 (GLP-1) receptor agonists. Renal outcomes are important. Next will be to see if it has cardiovascular benefit. It makes one think about its use versus GLP-1 agonists,” Dr. Gabbay said.
Managing type 2 diabetes: Shifting paradigms
With the emergence of tirzepatide and other pharmacologic agents with benefits beyond glucose lowering, there has been much discussion in recent years about alternatives to the current metformin monotherapy first, stepwise approach to managing type 2 diabetes.
As has been done previously, on Monday afternoon, there will be a joint ADA/European Association for the Study of Diabetes (EASD) session during which a draft of the latest update will be presented on the management of hyperglycemia in type 2 diabetes. The final version will be presented at the EASD meeting in September.
While it won’t include tirzepatide, as the drug is not yet approved in Europe, there will be discussion about the role of weight loss goals in type 2 diabetes management, Dr. Gabbay said.
The concept of a 15% weight loss as a primary treatment goal of type 2 diabetes management is a new focus, initiated at the EASD 2021 annual meeting and published in The Lancet.
“With tirzepatide becoming available, there’s the opportunity for more significant weight loss. So, there’s been this debate, starting with the somewhat controversial opinion piece in Lancet ... Maybe it was stating things a bit too far but it certainly got everyone in the field thinking. You’ll see that come up in lots of places at this meeting,” Dr. Gabbay said.
Indeed, those sessions include a Sunday morning symposium titled: “Obesity Management as a Primary Treatment Goal for Type 2 Diabetes – It’s Time for a Paradigm Shift,” in which speakers will address both lifestyle and pharmacologic intervention. On Saturday afternoon, two speakers will debate the question: “Weighing the Evidence – Should Obesity Be the Primary Target of Treatment in Type 2 Diabetes?” Yet another session on Sunday afternoon, will cover “Incorporating Weight Management Strategies for Obesity Into Type 2 Diabetes Care – Medical Management and Surgery.”
