The Next Wave of Weight Loss Drugs: CagriSema, MariTide, Survodutide & What's Coming After Wegovy

The GLP-1 revolution is just getting started. While Wegovy and Zepbound dominate the current market, pharmaceutical companies are racing to develop next-generation drugs that could deliver 25-30% weight loss — or offer entirely new delivery methods like monthly injections and unrestricted pills.

Here's a complete overview of every major obesity drug in late-stage development as of April 2026, with specific clinical trial data, expected timelines, and what each one means for patients.

CagriSema (Novo Nordisk) — Semaglutide + Amylin Analog

CagriSema is Novo Nordisk's answer to the competition from Eli Lilly. It combines two drugs in one once-weekly injection: semaglutide 2.4mg (the same active ingredient in Wegovy) plus cagrilintide 2.4mg, a long-acting amylin analog that enhances satiety through a separate brain pathway.

The REDEFINE 1 trial (published in NEJM, June 2025) enrolled 3,417 adults and showed:

Novo Nordisk filed the NDA on December 18, 2025. FDA approval is expected late 2026 to early 2027, with commercial launch around mid-2027.

Side effects in REDEFINE 1: nausea 55%, constipation 30.7%, vomiting 26.1%. Higher GI rates than semaglutide alone (79.6% vs 39.9% reporting any GI event), though most were mild-to-moderate and improved over time.

Retatrutide (Eli Lilly) — The Triple Agonist

We covered retatrutide in depth in our dedicated article. The key facts: it's a first-in-class triple agonist (GLP-1 + GIP + glucagon receptor) that achieved 28.7% weight loss in the TRIUMPH-4 Phase 3 trial — the highest ever recorded in an obesity drug trial.

NDA submission is expected Q4 2026 or Q1 2027, with potential FDA approval in late 2027 to early 2028. The unique addition of glucagon receptor agonism promotes fat oxidation and higher resting metabolic rate. One emerging safety signal to watch: dysesthesia (tingling/burning skin) was reported in 20.9% of patients at the 12mg dose.

Foundayo / Orforglipron (Eli Lilly) — Just Approved

Foundayo was FDA approved on April 1, 2026 — a once-daily oral pill that can be taken anytime, with no food or water restrictions. It achieved 12.4% weight loss at 72 weeks (less than injectables, but the most effective oral option). Starting at $149/month self-pay through LillyDirect. See our full breakdown for details.

MariTide (Amgen) — The Monthly Injection

MariTide (maridebart cafraglutide) takes a completely different approach. It's an antibody-peptide conjugate that combines GLP-1 agonism with GIP antagonism (the opposite of tirzepatide, which uses GIP agonism). Its 21-day half-life enables once-monthly dosing — a major convenience advantage over weekly injections.

Phase 2 data (presented at ADA June 2025, 592 participants) showed up to 20% weight loss at 52 weeks in patients without Type 2 diabetes, and up to 17% in those with T2D.

• •Dosing: Once monthly subcutaneous injection (vs weekly for all competitors)
• •Mechanism: GLP-1 agonist + GIP antagonist — novel dual mechanism
• •Status: Phase 3 (MARITIME program) actively enrolling
• •Timeline: FDA approval unlikely before 2028-2029
• •Key advantage: Monthly dosing could significantly improve adherence

Survodutide (Boehringer Ingelheim) — Obesity + Liver Disease

Survodutide is a glucagon/GLP-1 dual agonist (similar mechanism to retatrutide but without GIP). Phase 2 data showed up to 18.7% weight loss at 46 weeks at the 4.8mg dose, with 55% of patients achieving 15%+ loss.

What makes survodutide unique: it received FDA Breakthrough Therapy Designation in September 2024 for non-cirrhotic MASH (metabolic dysfunction-associated steatohepatitis) — formerly called NASH/fatty liver disease. This dual obesity + liver disease potential could differentiate it from pure weight loss drugs. Phase 3 SYNCHRONIZE trials are underway with results expected in 2026.

What This Means for You

If you're considering GLP-1 treatment today, here's the practical takeaway: don't wait for pipeline drugs if you qualify now. Wegovy and Zepbound are effective and available, and Foundayo just added a convenient pill option. Use our cost calculator to see what you'd pay, or take the match quiz to find the best provider.

However, if you're on semaglutide and curious about what's next — the landscape is about to get much more competitive. CagriSema, retatrutide, and MariTide all offer meaningful improvements in efficacy or convenience. We'll update this article as new trial results and approval decisions are announced throughout 2026-2027.
