Orforglipron vs Cagrilintide
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: LY3502970, OWL833
An oral non-peptide GLP-1 receptor agonist. FDA approved April 1, 2026 under the brand name Foundayo — the first daily oral GLP-1 pill for weight loss. Distribution began April 6, 2026. FDA subsequently requested additional post-approval safety data.
Also: AM833, NN9838
A long-acting amylin analog developed by Novo Nordisk for obesity treatment. Works through a different mechanism than GLP-1 agonists, targeting amylin receptors in the brain to reduce appetite and slow gastric emptying. Shows enhanced weight loss when combined with semaglutide (CagriSema).
Key Comparison Insights
- Orforglipron is FDA approved, while Cagrilintide remains in research stages.
- Both peptides belong to the Weight Loss category, suggesting similar primary applications.
Detailed Comparison
| Attribute | Orforglipron | Cagrilintide |
|---|---|---|
| Category | Weight Loss | Weight Loss |
| FDA Status | FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | Orforglipron is a small molecule that activates GLP-1 receptors similarly to peptide GLP-1 agonists. Being a non-peptide allows oral bioavailability without the special formulation needed for oral semaglutide. | Cagrilintide mimics amylin, a hormone co-secreted with insulin from pancreatic beta cells. It activates amylin and calcitonin receptors in the area postrema and nucleus tractus solitarius of the brainstem, enhancing satiety signaling. Unlike GLP-1 agonists, it works through homeostatic and hedonic appetite centers, reducing hunger and promoting earlier meal termination. Also slows gastric emptying to prolong fullness. |
| Common Dosing | Limited community data available See research protocols | 2.4 mg weekly Once weekly |
| Administration | Oral tablet daily | Subcutaneous injection once weekly |
| Typical Duration | Long-term use expected | Long-term / chronic use expected |
| Best Time to Take | Before bed or morning (fasted) | Any consistent time weekly |

| Research Summary | ATTAIN-1 Phase 3 results showed significant weight loss. ATTAIN-MAINTAIN showed it helps maintain weight after injectable GLP-1 treatment. NDA submitted late 2025. Selected for FDA National Priority Voucher program but review was delayed to April 2026. FDA approved Foundayo (orforglipron) on April 1, 2026 under the National Priority Voucher Program — the fastest new molecular entity approval since 2002. It is the first oral non-peptide GLP-1 receptor agonist approved for chronic weight management. | REDEFINE 1 Phase 3 trial showed 11.8% weight loss with cagrilintide monotherapy vs 2.3% placebo over 68 weeks. Combined with semaglutide (CagriSema), average weight loss reached 20.4% vs 3.0% placebo. 60% of CagriSema participants achieved ≥20% weight loss, and 23% lost ≥30%. This represents some of the most significant weight loss results seen with any anti-obesity medication. |
Frequently Asked Questions: Orforglipron vs Cagrilintide
What is the difference between Orforglipron and Cagrilintide?
Orforglipron is a weight loss peptide that an oral non-peptide glp-1 receptor agonist. fda approved april 1, 2026 under the brand name foundayo — the first daily oral glp-1 pill for weight loss. distribution began april 6, 2026. fda subsequently requested additional post-approval safety data. Cagrilintide is a weight loss peptide that a long-acting amylin analog developed by novo nordisk for obesity treatment. works through a different mechanism than glp-1 agonists, targeting amylin receptors in the brain to reduce appetite and slow gastric emptying. shows enhanced weight loss when combined with semaglutide (cagrisema). The main differences lie in their mechanisms of action and clinical applications.
Which is better, Orforglipron or Cagrilintide?
Neither is universally "better" - the choice depends on your specific goals. Orforglipron is typically used for weight loss purposes, while Cagrilintide is used for weight loss. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can Orforglipron and Cagrilintide be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using Orforglipron and Cagrilintide together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
