Protocol / Research Dosing Guide
An evidence-organized cagrilintide reference separating published clinical-trial designs from unapproved research-vial calculations and vendor claims.
Cagrilintide is a long-acting amylin analogue developed for once-weekly subcutaneous research. Randomized trials have evaluated it alone and with semaglutide, but trial parameters are not an approved regimen and vendor vials are not clinical-trial products.
Why researchers care
Appetite, weight, and metabolic research
Class
Long-acting acylated amylin analogue
Route reported
Subcutaneous once weekly in clinical trials
Cycle length
26–68 weeks studied; no approved cycle
Regulatory status
Investigational; not FDA approved
The supplied source presents a 0.25-to-2.4 mg weekly titration. Published trials studied several weekly doses, including up to 4.5 mg in Phase 2; the exact ladder shown here is source reported and is not an approved label.
| Phase or study | Amount | Frequency / evidence |
|---|---|---|
| Weeks 1–4 | 0.25 mg weekly | Coverage-source ladder |
| Weeks 5–8 | 0.5 mg weekly | Coverage-source ladder |
| Weeks 9–12 | 1.0 mg weekly | Coverage-source ladder |
| Weeks 13–16 | 1.7 mg weekly | Coverage-source ladder |
| Week 17+ | 2.4 mg weekly | Coverage-source target; not approved |

| Route | Research context | Evidence limit |
|---|---|---|
| Subcutaneous | Once weekly in human trials | Investigational study administration |
| Oral | Not established | No validated oral exposure regimen |
| Vendor research vial | Commercially listed | Not equivalent to trial material |
| Route conversion | Not established | No interchangeable-route formula |
Routes and amounts are not interchangeable unless a verified study explicitly establishes a conversion.
| Measure | Finding | Evidence limit |
|---|---|---|
| Reported human half-life | Approximately 159–195 hours | Supports weekly trial design |
| Peak concentration | Not established here | Depends on formulation and study |
| Steady state | Not established for vendor vials | Trial formulation cannot be assumed |
| Long-term accumulation | Not established | No approved-use specification |
| Route | Amount | Frequency | Source | Human validation |
|---|---|---|---|---|
| Subcutaneous trial | 0.3–4.5 mg | Once weekly for 26 weeks | Randomized Phase 2 | Study design |
| Subcutaneous | 0.25 mg | Weekly, weeks 1–4 | Coverage source | Not approved |
| Subcutaneous | 0.5–1.7 mg | Four-week steps | Coverage source | Not approved |
| Subcutaneous | 2.4 mg | Weekly from week 17 | Coverage source | Not approved |
Published study values describe those studies. Community-reported values are not validated dosing recommendations.
