There’s not a body out there that’s better than your own. It’s the vehicle that takes you through life. And no matter what size, shape, or height it is, there are countless reasons to be proud of it.

Still, some internal or external factors may be driving you to try to lower your body weight. Perhaps, it’s wanting to improve your body image. Or maybe it’s related to a health issue your prescriber warned you about. Regardless, there are steps you can take to help you meet your health goals.

When possible, a nutritious diet and routine exercise are ideal ways to lose body weight. But, if needed, medication is another way to help promote weight loss. While there are multiple weight-loss medications already on the market, there are also several new weight-loss drugs in clinical trials. Here are 14 prospects to keep in mind.

1. Aleniglipron

What it is: Aleniglipron (GSBR-1290) is a oral glucagon-like peptide-1 (GLP-1) medication in development for chronic weight management and Type 2 diabetes. It works in a similar way to Foundayo (orforglipron), which was FDA approved in April 2026.

How it’s administered: Aleniglipron is a once-daily pill.

Status: Aleniglipron’s manufacturer, Structure Therapeutics, released phase 2 study data in late 2025. Phase 3 studies will likely start in the second half of 2026.

Effectiveness: Compared to placebo, aleniglipron helped study participants lose an average of 11% to 15% of their initial body weight after 36 weeks (8 months) of use (depending on the dose).

April 1, 2026

Aleniglipron showed more promising results in a recent phase 2 trial. In the study, people taking higher doses lost about 16% of their body weight over 44 weeks (about 10 months), with continued weight loss seen beyond 1 year and no clear plateau. The medication also showed a safety and side effect profile similar to other GLP-1 drugs.

These results suggest it could offer injection-like effectiveness in a pill form, though it’s still being studied. The company plans to begin phase 3 trials in the second half of 2026, which will be needed before FDA approval.

2. APHD-012

What it is: APHD-012 is an oral medicine that imitates the metabolic effects of gastric bypass (weight loss) surgery. It’s a glucose pill that’s designed to stimulate certain parts of your small intestine.

How it’s administered: APHD-012 is a once-daily oral medication. Its manufacturer is calling it a distal jejunal-release dextrose bead.

Status: APHD-012 is now engaged in its second phase 2 study. It kicked off in September 2025.

Effectiveness: We don’t know exactly how effective APHD-012 will be for weight loss. Stay tuned for updates.

October 1, 2024

APHD-012 is also being studied for prediabetes. A phase 2 study found that the medication helps improve glucose tolerance in adults with prediabetes. After taking the medication once daily for 6 weeks, people in the study were able to perform better on an oral glucose tolerance test (OGTT). An OGTT is a diagnostic tool that helps evaluate how well your body is able to process sugars. The medication was also well tolerated overall.

3. ARD-101

What it is: ARD-101 is an oral medication. It targets “bitter taste receptors” in your gut and activates appetite-suppressing hormones such as GLP-1, glucagon-like peptide-2 (GLP-2), and cholecystokinin. ARD-101's manufacturer is also developing similar medication called ARD-201, which combines ARD-101 with a dipeptidyl peptidase-4 (DPP-4) inhibitor.

How it’s administered: ARD-101 is an oral pill that’s taken twice daily.

Status: ARD‑101 has completed several phase 2 studies in adults considered obese, people who’ve had weight‑loss surgery, and people with Prader-Willi syndrome (PWS) — a genetic condition that causes a hard-to-satisfy appetite. A phase 3 study to test ARD‑101 for hard-to-treat hunger in PWS is now underway.

Effectiveness: Current data suggests that ARD-101 reduces hunger 2.5 times more than placebo among adults who are considered obese. This may lead to weight loss.

Latest news on ARD-101

April 1, 2026

Aardvark Therapeutics has paused mid-stage trials of its oral obesity drug, ARD-201. It also put its broader pipeline on hold while it's reviewing safety data. The decision follows earlier cardiac safety concerns seen with ARD-101, including reversible heart-related issues at higher doses.

The company is now working with the FDA to determine next steps. It’s unclear when trials will resume, but updates are expected later in 2026.

4. Oral amycretin

What it is: Amycretin is an oral medication that’s being developed for chronic weight management. It’s a dual GLP-1 and amylin receptor agonist. Amylin is a hormone that helps you feel more full after meals.

How it's administered: Amycretin is a once-daily oral tablet. But an under-the-skin amycretin injection is being developed too.

Status: Amycretin is advancing into phase 3 studies. An executive at Novo Nordisk predicted that amycretin will likely be available sometime this decade (before 2030).

Effectiveness: In an early stage study, people taking amycretin lost an average of 13% of their initial body weight after 12 weeks (3 months) of use.

Latest news on amycretin

December 1, 2025

Novo Nordisk shared in June 2025 that it’s moving both the injectable and pill forms of amycretin into phase 3 clinical trials for chronic weight management. The decision came after early studies involving people who are considered obese showed significant and lasting weight loss.

In November 2025, the company announced plans to begin phase 3 studies next year to see how well the medication works for treating diabetes.

5. Monlunabant

What it is: Monlunabant is an oral medication in development for chronic weight management and other metabolic disorders. A  small molecule oral cannabinoid receptor 1 (CB1) inverse agonist, it’s thought to help lessen your appetite and support your metabolism.

How it’s administered: Monlunabant is an oral tablet taken once daily.

Status: Monulubant’s manufacturer, Novo Nordisk, released an initial set of phase 2 trial results in September 2024. At this time, the medication’s next steps are somewhat unclear.

Effectiveness: In a phase 2 study, people who took monlunabant lost an average of 15 lbs (7 kg) after 16 weeks (4 months) of use. By comparison, people taking placebo lost a little less than 1 kg (1 lb to 2 lbs).

Latest news on monlunabant

March 1, 2025

As with many other weight-loss medications, monulubant is linked to mild to moderate GI-related side effects. But it may also cause some brain-related side effects, especially at higher doses. Some people taking the medication in clinical trials have reported feelings of irritability, anxiety, and/or sleep troubles. Monlunabant’s side effect profile will continue to be evaluated in upcoming studies.

6. Retatrutide

What it is: Retatrutide is a medication that’s being studied for weight loss and Type 2 diabetes in adults. Retatrutide works by attaching to three receptors (binding sites): GIP (glucose-dependent insulinotropic polypeptide), GLP-1, and glucagon.

How it’s administered: Retatrutide is an injectable medication that’s administered under the skin once weekly.

Status: A phase 3 weight loss study is currently in process. It’s set to finish by early 2026. If data is positive, a FDA approval request will likely follow.

Effectiveness: Eli Lilly, the manufacturer of retatrutide, estimates that the medication may help people lose up to an average of 29% of their initial body weight after about 68 weeks (15 months). It may be even more effective than Zepbound (tirzepatide) for weight loss. Other papers speak to its significant weight loss benefits, too.

Latest news on retatrutide

August 1, 2025

A recently published meta analysis concluded that retatrutide led to the most weight loss among GLP-1-based treatments, but it also caused the most side effects. Dual agonists, such as tirzepatide and survodutide (more details below), produced similar weight loss to retatrutide with fewer side effects. Traditional GLP-1 medications were effective, but resulted in less weight loss overall.

7. CagriSema

What it is: CagriSema is a combination treatment that combines two injectable medications (cagrilintide and semaglutide) into one. Cagrilintide mimics amylin, while semaglutide mimics GLP-1.

How it’s administered: CagriSema is an injectable medication that’s administered under the skin once weekly.

Status: CagriSema's manufacturer, Novo Nordisk, applied for the medication's FDA approval in December 2025. An approval decision will likely come sometime in 2026.

Effectiveness: CagriSema demonstrated meaningful weight-loss effects in two phase 3 studies. After about 68 weeks (15 months), adults without diabetes lost about 20% of their body weight on average. Adults living with Type 2 diabetes saw about 14% weight loss along with improvements in blood sugar readings.

Latest news on CagriSema

April 2, 2026

A recent meta-analysis presented at an American cardiology conference found that CagriSema led to greater weight loss than its individual ingredients, cagrilintide and semaglutide. It also led to greater improvements in blood sugar, waist circumference, and blood pressure.

The researchers ultimately suggested that CagriSema could be a strong first-choice medication for weight-loss, though longer-term safety data are still needed.

8. Ecnoglutide

What it is: Ecnoglutide (also called XW003) is another GLP-1 receptor agonist. It’s thought to be a longer-lasting alternative to Saxenda (liraglutide). Saxenda is a once daily, injectable GLP-1 receptor agonist that’s approved for weight loss.

How it’s administered: Ecnoglutide is an injectable medication that’s administered under the skin once weekly. An oral version is also in the works.

Status: Ecnoglutide has been studied in several Chinese phase 3 studies for weight loss and Type 2 diabetes in adults. A new study is now seeing how it stacks up to semaglutide for weight loss.

Effectiveness: In a 40-week (about 9 months) phase 3 study, people using ecnoglutide lost about 9% to 13% of their body weight on average, depending on the dose. Meanwhile, those taking a placebo saw little to no change.

Latest news on ecnoglutide

August 1, 2025

Sciwind Biosciences, the Chinese company developing ecnoglutide, recently stated that its negotiating with an unnamed American company to license the medication in the U.S. The company hopes the partnership will eventually lead to FDA approval and allow the use of existing clinical data from China and Australia to help speed up the approval process.

9. Mazdutide

What it is: Mazdutide (also called IBI362) is a GLP-1 receptor agonist that also mimics glucagon. It’s being studied for weight loss and Type 2 diabetes in adults.

How it’s administered: Mazdutide is an injectable medication that’s administered under the skin once weekly.

Status: Mazdutide has completed several phase 3 studies in China. A new one kicked off in December 2025 and is set to run through 2028.

Effectiveness: In a phase 3 trial, mazdutide 9 mg led to an average weight loss of about 19% over 60 weeks (about 13 months), with no clear plateau during treatment. Among people without Type 2 diabetes, weight loss was even greater. Nearly half of participants lost at least 20% of their initial body weight.

Latest news on mazdutide

November 1, 2025

In a head-to-head phase 3 trial, mazdutide 6 mg outperformed semaglutide 1 mg among people with Type 2 diabetes and obesity. About 48% of people taking mazdutide achieved both at least 10% weight loss and target A1C levels, compared to roughly 21% with semaglutide.

10. Survodutide

What it is: Survodutide activates GLP-1 and glucagon receptors, similar to mazdutide.

How it’s administered: Survodutide is an injectable medication that’s administered under the skin once weekly.

Status: Survodutide completed its phase 2 clinical studies. Phase 3 studies are set to run through April 2026, and the corresponding data should be released during the first half of the year.

Effectiveness: Participants in a phase 2 study lost up to 19% of their initial body weight after using survodutide for about 46 weeks (10 months). Everyone in the study was considered overweight or obese.

Latest news on survodutide

April 12, 2024

Survodutide may be able to treat metabolic dysfunction-associated steatohepatitis (MASH), a form of metabolic dysfunction-associated steatotic liver disease (MASLD). People who are considered overweight or obese have a higher risk for developing MASH.

In a recent 48-week phase 2 study, over 80% of people who received survodutide experienced significant improvements in their liver biopsy reports. By comparison, nearly 20% of people receiving a placebo saw similar results.

11. VK2735

What it is: VK2735 is a GLP-1/GIP receptor agonist medication, similar to tirzepatide.

How it's administered: VK2735 is injected under the skin once weekly. A tablet version of the medication is also in the works, but it’s in earlier stages of development.

Status: Injectable VK2735 has completed its phase 2 trial for weight loss. The study kicked off in September 2023, and it ended in the first portion of 2024. Its 78-week, phase 3 study is actively underway.

Effectiveness: Phase 2 data found that injectable VK2735 helped people lose up to nearly 15% of their initial body weight after 13 weeks (roughly 3 months) of use.

Latest news on VK2735

December 1, 2025

In a phase 2 dosage trial, an oral version of VK2735 helped adults considered obese lose up to about 12% of their body weight in 13 weeks (3 months). People taking a placebo lost only about 1% during the same time. The study met all its main goals, with every dose of VK2735 leading to significantly more weight loss than placebo.

12. MariTide

What it is: MariTide is short for maridebart cafraglutide. It’s an injectable medication that mimics GLP-1 but blocks GIP. This is a different approach from medications such as tirzepatide and VK2735. Some genetic research suggests that blocking GIP in the gut may lead to less fat storage. MariTide is being studied for chronic weight management.

How it's administered: MariTide is injected under the skin. A big part of what makes it unique is its frequency of administration, as it’s only injected once a month.

Status: MariTide is currently being studied in several phase 3 trials. According to its manufacturer, six global studies are in progress, focusing on obesity and related conditions such as heart disease and sleep apnea.

Effectiveness: In a phase 2 study, MariTide helped people considered obese lose up to about 20% of their body weight over a year. People living with obesity and Type 2 diabetes saw up to about 17% weight loss; they also saw better blood sugar levels and improvements in metrics such as waist size, blood pressure, and inflammation. Because weight loss was still ongoing at 52 weeks, researchers believe people may lose even more weight with longer treatment.

Latest news on MariTide

October 1, 2024

The CEO of Amgen, the company that’s developing MariTide, noted at a conference that they plan to study MariTide for a variety of weight-related health conditions in phase 3 trials. This includes conditions related to the heart, liver, and kidneys.

Medications that are solely FDA approved for weight loss aren’t typically covered by insurance. Obtaining these additional approvals could potentially pave the way for insurance coverage of MariTide in the future.

13. PF-08653944

What it is: PF-08653944 (also called PF’3944) is an ultra-long-acting GLP-1 receptor agonist in development for weight loss. While most GLP-1 injections are administered once a week, PF-08653944 is being studied as a once-monthly shot.

How it’s administered: PF-08653944 is given as a once-monthly injection under the skin.

Status: Pfizer, its manufacturer, plans to advance several phase III clinical trials in 2026. These studies will further evaluate PF-08653944’s efficacy and safety across different dosage schedules and patient groups.

Effectiveness: In a phase 2 study, adults with overweight or obesity who received PF-08653944 lost more weight than those who received a placebo after about 6 to 7 months. People received weekly injections for the first 12 weeks and then switched to just one injection per month through week 28. Weight loss continued even after switching to monthly shots and didn’t appear to stall.

Latest news on PF-08653944

February 3, 2026

Pfizer recently shared early results from a phase 2 clinical trial of its experimental weight-loss medication, PF-08653944. The study looked at adults with overweight or obesity who don’t have Type 2 diabetes.

People taking the medication lost significantly more weight than those receiving a placebo. On average, participants lost up to about 12% more body weight than the placebo group after 28 weeks. Importantly, weight loss continued even after participants switched from weekly injections to once-monthly injections — meaning the benefits didn’t level off when doses became less frequent.

The medication’s side effects were similar to those seen with other GLP-1 medications, such as nausea and other digestive symptoms, and were generally manageable.

14. Eloralintide

What it is: Eloralintide (LY3841136) is a selective amylin receptor agonist in development for weight loss.

How it’s administered: Eloralintide is given as a once‑weekly injection under the skin.

Status: Eloralintide recently completed a phase 2 clinical trial in adults with larger body sizes. Eli Lilly, its manufacturer, kicked off phase 3 studies in late 2025 and early 2026 to further evaluate its safety and effectiveness for long‑term weight management and related health conditions.

Effectiveness: In a phase 2 study, people receiving weekly eloralintide lost an average of up to 20% of their body weight after 48 weeks (11 months), depending on the dose. The treatment was also linked to improvements in waist size, blood pressure, and cholesterol, all of which play a role in heart health.

Latest news on eloralintide

November 15, 2025

Eli Lilly recently announced that every eloralintide dose group in its phase 2 trial hit the study’s main weight-loss goals. The company is now preparing for phase 3 testing, and many experts are watching to see whether this amylin-based medication could match — or even work alongside — today’s GLP-1 medications for weight loss.

What medications are already FDA approved for weight loss?
