## Elimination Kinetics & 97% Washout Benchmark for Semaglutide vs CagriSema

- **Documented Elimination Half-Life (T½):** Semaglutide: ~7 days | Cagrilintide: ~7 days
- **Steady-State Equilibrium Window:** Achieved after 4.0 to 5.0 consecutive half-lives of regular administration.
- **97% Systemic Washout Threshold:** Requires 5.0x elimination half-lives following final dose administration.
- **Optimal Administration Schedule:** Subcutaneous injection once weekly.
