Mecasermin (Increlex) vs Somatrogon (Ngenla)
An educational, source-based comparison of Mecasermin (Increlex) and Somatrogon (Ngenla) — how each peptide works, what it's researched for, and what to know before going deeper.
Recombinant human insulin-like growth factor-1 (rhIGF-1) that binds IGF-1 receptors to promote linear growth in children with severe primary IGF-1 deficiency or GH gene deletion with anti-GH antibodies.
- Severe primary IGF-1 deficiency
- Growth failure with GH gene deletion and neutralizing GH antibodies
- • FDA-approved.
- • Hypoglycemia — must be taken with food.
- • Tonsillar hypertrophy, intracranial hypertension reported.
Long-acting recombinant human growth hormone for pediatric GH deficiency — weekly dosing.
A long-acting recombinant fusion protein of human growth hormone with three copies of the C-terminal peptide (CTP) of hCG beta-subunit, extending half-life and enabling once-weekly subcutaneous dosing instead of daily.
- Pediatric growth hormone deficiency
- • FDA-approved June 2023.
- • Same class warnings as daily GH (intracranial hypertension, glucose effects, scoliosis progression).
- • Injection-site reactions common.
