Compound Reference Overview
| Field | Value |
|---|---|
| Name | Cagrilintide |
| Reference Code | CAGRI |
| Category | Long-Acting Amylin Analog (Investigational) |
| Example Strength | 0.25 mg, 0.5 mg, 1.0 mg, 1.7 mg, 2.4 mg (clinical trial doses; investigational) |
| Reference Range | 0.25 mg – 2.4 mg once weekly (evaluated in Phase 2/3 clinical programs) |
| Frequency | Once weekly (clinical trial reference) |
| Key Safety Warning | Investigational Status: Cagrilintide is not FDA approved. As an amylin analog, it slows gastric emptying and may increase gastrointestinal adverse events. Use caution in patients with severe gastrointestinal motility disorders (e.g., gastroparesis). |
Mechanism of Action (Educational)
Cagrilintide is a long-acting analog of amylin, a peptide hormone co-secreted with insulin by pancreatic beta cells. It activates amylin receptors in the area postrema and other central appetite-regulating regions of the brain.
Amylin receptor activation is associated with delayed gastric emptying, increased satiety, reduced caloric intake, and suppression of postprandial glucagon secretion. These mechanisms form the basis for its investigation in obesity and metabolic disease, including combination programs with GLP-1 receptor agonists (e.g., CagriSema).
Indications (Investigational)
- Obesity (Phase 2 and Phase 3 development)
- Type 2 diabetes mellitus (clinical development)
- Combination therapy with semaglutide (CagriSema programs)
Administration (Clinical Trial Reference)
| Parameter | Details |
|---|---|
| Route | Subcutaneous |
| Frequency | Once weekly |
| Injection Sites | Abdomen, thigh, or upper arm (rotate sites) |
| Timing | Administered on the same day each week |
Pharmacokinetics (Clinical Trial Data)
Cagrilintide demonstrates a prolonged duration of action consistent with once-weekly administration. Clinical trial materials report an approximate half-life of ~6–8 days, supporting weekly dosing schedules.
Steady-state concentrations are achieved after several weeks of administration. Metabolism occurs through peptide degradation pathways similar to other therapeutic peptides.
Titration Schedule (Clinical Trial Reference)
The following escalation reflects dosing strategies evaluated in investigational programs and is provided for literature reference only.
- Weeks 1–4: 0.25 mg once weekly
- Weeks 5–8: 0.5 mg once weekly
- Weeks 9–12: 1.0 mg once weekly
- Weeks 13–16: 1.7 mg once weekly
- Week 17+: 2.4 mg once weekly
Gradual escalation is recommended to improve gastrointestinal tolerability. Slower titration may reduce the incidence and severity of nausea and vomiting.
Reconstitution & Concentration (Mathematical Standardization Model)
For educational standardization purposes, concentration may be normalized so that 0.10 mL (10 insulin units) = 0.25 mg. This supports clean unit-to-milligram conversion across the investigational escalation steps.
| Parameter | Value |
|---|---|
| Target Concentration | 2.5 mg/mL |
| Unit Conversion | 0.10 mL (10 units) = 0.25 mg |
| Example (10 mg vial) | Reconstitute with 4.0 mL bacteriostatic water → 2.5 mg/mL |
| Stability | Up to 28 days refrigerated (varies by formulation and compounding standards) |
Conversion Reference
- 10 units = 0.25 mg
- 20 units = 0.5 mg
- 40 units = 1.0 mg
- 68 units = 1.7 mg
- 96 units = 2.4 mg
