Canadian scientist wins Breakthrough Prize for discovery of hormone used in Ozempic, Mounjaro

A Canadian researcher has won a 2025 Breakthrough Prize successful Life Sciences for discovering the GLP-1 hormone utilized in diabetes and obesity medications — including Ozempic, Wegovy and Mounjaro — that person changed the lives of millions of radical astir the world.

Dr. Daniel Drucker, an endocrinologist and a clinician-scientist astatine the University of Toronto and the Lunenfeld-Tanenbaum Research Institute astatine Sinai Health, shares the $3 cardinal US prize with 4 colleagues from the United States and Denmark.

They were each progressive successful the improvement of the now-famous drugs manufactured by Novo Nordisk and Eli Lilly. Drucker and 3 co-winners made discoveries astir glucagon-like peptide-1 successful their labs. The different recipient of the award, Lotte Bjerre Knudsen, who works for Novo Nordisk, led the mode successful processing it into medications.

The Breakthrough Prizes, often referred to arsenic the "Oscars of Science," were handed retired Saturday successful Los An​geles for categories including cardinal physics and mathematics, successful summation to beingness sciences.

The Breakthrough Foundation says the prizes were created to "celebrate the wonders of our technological age." Another Canadian, Maaike van Kooten of National Research Council Canada, shared a $100,000 US prize called New Horizons successful Physics with 2 planetary colleagues for enactment successful optics to presumption exoplanets.

In an interrogation successful the week anterior to the event, Drucker said the prize is meaningful due to the fact that it's awarded by different scientists and "gets a batch of attraction successful the technological community."

"We person students and trainees and awards similar this archer them that the satellite is watching and thinks the enactment is meritorious. And I deliberation that's conscionable large for morale and for young people," helium said.

Drucker began his travel studying familial sequencing of glucagon-like peptides astatine a laboratory successful Boston successful the 1980s, past returned to Canada and continued his enactment astatine the University of Toronto.

He spoke with The Canadian Press astir those aboriginal days, what helium thinks astir however the resulting medications person changed the world's presumption of obesity and what different wellness issues GLP-1 mightiness code successful the future.

This interrogation has been edited for magnitude and clarity.

When you started astatine that laboratory successful Boston, wherefore were you studying this peculiar hormone?

"There were astir apt astir a twelve projects successful the laboratory astatine that time. So immoderate radical were moving connected pituitary hormones. Some radical were connected basal compartment biology projects. Other radical were moving connected antithetic genes and glucagon was 1 of the projects successful the lab.... It conscionable truthful happened erstwhile I got there, they said, 'OK Drucker, you enactment connected the glucagon gene.' [It] could person been different cistron [and] you ne'er would person heard from maine again.

Were determination immoderate cardinal moments wherever you thought, 'Wow, this is simply a large deal?'

"I don't deliberation determination was immoderate 1 'Eureka!' moment, but I volition accidental the imaginable value dawned connected maine erstwhile I walked into the laboratory 1 time and my notebooks were gone. And I said, 'Oh my gosh, idiosyncratic broke into the laboratory and stole my notebooks.' And past it turned retired nary — my supervisor [and a chap prize winner], Joel Habener, took my notebooks due to the fact that helium was excited capable astir the results to record a patent."

When did you travel to the University of Toronto?

"I came backmost successful 1987.... In 1996, erstwhile we and others discovered that GLP-1 inhibits nutrient intake, that was successful my laboratory successful Toronto, and we've done experiments connected bosom illness and inflammation and kidney illness and liver disease. So I virtually person been moving connected this for 40 years."

When did Novo Nordisk (manufacturer of Ozempic and Wegovy) go involved?

"I deliberation the large companies, Novo Nordisk and Eli Lilly, and adjacent different companies were trying from the opening to make medicines based connected GLP-1. But we learned done immoderate achy lessons that if you springiness excessively overmuch GLP-1 excessively quickly, radical propulsion up. It's inactive a broadside effect today, right? Some radical conscionable don't consciousness good and they person immoderate nausea and vomiting. And truthful it took the pharmaceutical manufacture rather a portion to fig retired however to marque GLP-1 past longer truthful it's not breached down, however to springiness tiny amounts to commencement disconnected with, however to dilatory physique up the dose, et cetera. And that took years to do."

What are you moving connected present and what are immoderate other applications for GLP-1 drugs?

"If we conscionable look successful the past mates of years, beyond lowering humor sweetener and beyond reducing assemblage weight, we person seen that these medicines trim the rates of bosom attacks and strokes and trim the rates of diabetic kidney illness and are adjuvant for radical with obstructive slumber apnea and trim disablement successful people with arthritis and forestall the improvement of terrible metabolic liver disease. And determination are trials underway successful Parkinson's disease, in Alzheimer's disease, successful substance usage disorders. 

"So I benignant of look astatine this and I go, 'Wow, however does that happen? What are the things that GLP-1 is doing successful the encephalon oregon successful the humor vessels oregon successful the kidney to amended the wellness of these organs?' So we're truly focused connected this facet of GLP-1, including however GLP-1 reduces inflammation, which we deliberation is simply a large portion of the benefits that GLP-1 brings to the table." 

Are cardiovascular benefits due to the fact that GLP-1 medication reduces value oregon manages diabetes and that improves cardiovascular health?

"What we're starting to spot is that successful galore of the trials, the benefits don't strictly correlate with value nonaccomplishment oregon humor sweetener control. So there's nary question [that] getting your humor sweetener mean if you person Type 2 diabetes, reducing your assemblage value if it's excessively high, that's helpful.

"But erstwhile we really look astatine the trials and we spot who has the payment and who doesn't, there's not a cleanable correlation with humor sweetener power oregon value loss. And truthful we deliberation determination are, you know, autarkic actions of GLP-1, possibly done simplification of inflammation, that are besides beneficial. And this is precisely what we effort and survey successful the lab."

We're present seeing a civilization displacement successful however we presumption obesity. What bash you marque of that?

"It's a precise analyzable discussion. So let's accidental 10 years ago, we had a precise understandable movement, which was 'healthy astatine immoderate size.' Don't absorption connected your value per se, absorption on your health, which I inactive deliberation is simply a precise almighty message. And portion of that messaging was due to the fact that we didn't person solutions other than bariatric country to let radical to go healthier, perhaps at a little assemblage weight.... And successful society, determination tends to beryllium a segment of our nine that looks astatine radical surviving with obesity and says, 'Well, you know, it's conscionable willpower. If you truly wanted to suffer weight, you could, you're conscionable not trying' or 'You're lazy,' or you know, 'You're weak.'

"And we cognize that galore of these people that we spot successful objective signifier person been connected precise calorie-reduced diets and moving retired and doing everything that we asked them to do. But their brains are defending a higher assemblage weight.... And present with the GLP-1 medicines, we spot that... we tin assistance radical suffer weight. And I deliberation this is precise almighty due to the fact that the radical who were struggling earlier who could not bash it by themselves tin present suffer 10, 15, 20, 30, 50 pounds."

Do you person immoderate trepidation oregon thoughts astir these drugs being utilized by radical who whitethorn not request them?

"Well, you're speaking to the idiosyncratic who worries astir everything, truthful of people I person concerns... It's been a small spot similar The Hunger Games. People have to telephone six pharmacies and find 1 that had a month's worth of drugs and past thrust arsenic accelerated arsenic they could to that drugstore to get them, which is not great. And truthful portion that's happening, to spot different radical getting a medicine due to the fact that Uncle Harry's wedding is coming up successful 2 months and they conscionable privation to suffer a small spot of weight truthful they tin look a small much acceptable astatine Uncle Harry's wedding — you know, arsenic a physician, I say, 'Wait a sec, this idiosyncratic living with bosom illness and Type 2 diabetes needs these medicines to trim the hazard of bosom attacks and strokes. Maybe that should beryllium a priority arsenic a nine implicit you looking a small amended for Uncle Harry's wedding.' So that's been 1 dilemma.

"And past the different large situation that we inactive person is these medicines are precise expensive. In galore jurisdictions, we don't have everyone with entree to a cause plan. We don't [have] every cause plan agreeing to reimburse for the medicines.

"And finally... we don't person objective trials connected healthier people without diabetes, without a higher assemblage value that are studied [to know], 'Well, are determination immoderate peculiar broadside effects in this radical of individuals?' They weren't studied successful the clinical trials. Is determination thing we should beryllium disquieted about, going connected and  disconnected the drugs erstwhile you privation to suffer weight...is that healthy? We don't know. And truthful we person to ever beryllium mindful of what we don't cognize astir the information of these medicines."
