Key takeaways:
CagriSema is an investigational medication that consists of two active ingredients: cagrilintide and semaglutide. It’s being studied for weight loss, Type 2 diabetes, and heart protection. A trial is also comparing CagriSema to Zepbound (tirzepatide).
During clinical trials, people who didn’t have diabetes lost nearly 23% of their starting body weight with CagriSema. People with Type 2 diabetes lost about 16% on average.
CagriSema’s manufacturer has plans to start a new, longer study in 2025 and is aiming to submit an application for FDA approval in early 2026.
Glucagon-like peptide-1 (GLP-1) medications such as Wegovy (semaglutide) and Zepbound (tirzepatide) have reshaped the approach to weight loss. But they’re just the beginning. Several next-generation GLP-1-based treatments are in development, including CagriSema, which could be available in the near future.
Similar to Wegovy and Zepbound, CagriSema is administered as a once-weekly, subcutaneous (under-the-skin) injection. But it consists of cagrilintide and semaglutide, targeting multiple pathways that regulate appetite and fullness.
How does CagriSema compare to other GLP-1s, and when might it be available? Here’s what you need to know.

CagriSema is an investigational medication being developed for weight loss, Type 2 diabetes, and cardiovascular risk reduction. It consists of two active ingredients given as a once-weekly injection:
Cagrilintide: a new long-acting amylin analog
Semaglutide: a GLP-1 receptor agonist found in Wegovy, Ozempic, and Rybelsus
These ingredients typically can’t be mixed into a single solution, so it was thought that CagriSema would need to come in a dual-chamber pen injector. This pen would keep the medications separate until the time of injection and then deliver both at the same time. However, the manufacturer recently tested CagriSema in a single-chamber FlexTouch pen (the same one used for Ozempic), which would make the medication easier to make and use.
Cagrilintide and semaglutide mimic natural gut and pancreatic hormones that help regulate appetite, digestion, and blood glucose (blood sugar) levels, but they act on different pathways. When used together, they enhance each other’s effects for greater results than either medication can deliver alone.
Cagrilintide mimics amylin, a hormone that’s released by the pancreas with insulin after eating. It helps:
Slow stomach emptying
Increase feelings of fullness so you eat less
Manage postmeal blood sugar spikes

How it works: Semaglutide is one of the active ingredients in CagriSema. Here’s what you should know about semaglutide for weight loss.
GLP-1 comparison: Glucagon-like peptide-1 (GLP-1) medications such as semaglutide are FDA approved for Type 2 diabetes and weight loss, among other uses. Here’s how GLP-1s compare.
Semaglutide works by mimicking a gut hormone called GLP-1, which has the following effects:
Increases insulin release after a meal
Reduces sugar production in the liver
Slows how quickly food leaves the stomach
Reduces hunger by acting on the appetite centers in the brain
CagriSema has been studied in people with a larger body size. Here’s a summary of key results after 68 weeks (almost 16 months) of treatment.
Population | Average weight loss | Additional notes |
---|---|---|
Adults who didn’t have diabetes (REDEFINE 1) | Nearly 23% of body weight | About 40% of participants had weight loss of 25% or more. |
Adults who had diabetes (REDEFINE 2) | Almost 16% of body weight | Most participants achieved at least 5% weight loss. |
In people who didn’t have Type 2 diabetes, CagriSema fell slightly short of the company’s 25% weight-loss target, possibly because only about half of the participants reached the highest dose. The manufacturer is now planning to do a longer trial in 2025 that will focus on adjusting doses to give participants more time to safely work up to the highest dose.
In addition to weight loss, CagriSema is also being studied for potential cardiovascular benefits. And in another study, it’s being directly compared to Zepbound, which has shown to be the most effective weight-loss medication on the market so far.
The most common side effects reported with CagriSema are similar to those seen with other GLP-1 medications. These side effects include:
Nausea
Vomiting
Diarrhea
Constipation
Loss of appetite
These effects are generally mild to moderate and may lessen over time. Serious side effects have been rare. But CagriSema may not be safe for everyone. Similar to other GLP-1s, it may not be recommended for people who:
Have a personal or family history of medullary thyroid cancer
Have multiple endocrine neoplasia syndrome type 2 (MEN2)
Have a severe digestive disorder, such as gastroparesis
Are pregnant or nursing
If approved, CagriSema will work differently compared to other GLP-1 medications on the market. Compared to semaglutide alone, it has resulted in greater weight loss. And we’ll know more about how it compares to tirzepatide once the head-to-head trial results are available.
Here’s an overview of GLP-1 study results for weight loss.
Medication | Ingredient(s) | Average percentage of body weight lost* | |
---|---|---|---|
CagriSema | Cagrilintide and semaglutide | Results after 68 weeks:
|
Not yet approved |
Wegovy | Semaglutide | Results after 68 weeks: |
|
Zepbound | Tirzepatide | Results after 72 weeks: |
|
Saxenda | Liraglutide | Results after 56 weeks: |

*These outcomes come from different studies conducted under different conditions, so they may not be directly comparable. |
As mentioned above, the manufacturer is planning a new trial in 2025. But because of positive results from clinical trials, they plan to submit an application for FDA approval in early 2026.
If approved, CagriSema could be available as soon as late 2026. Additional trials are still underway to better understand its long-term benefits and how it compares to other leading treatments.
