- Comparison of commonly applied long-acting strategies in peptide development. Selection should be based on exposure goals, molecular constraints, and development complexity.
- Lipidation (Fatty Acid Conjugation)
- Reversible albumin binding reduces clearance
- Low increase
- Generally predictable when properly calibrated
- Chronic systemic therapies
- PEGylation / Polymer Conjugation
- Increased hydrodynamic size reduces renal filtration
- Moderate increase
- Variable depending on conjugation site
- Moderate to High
- Exposure extension when activity tolerance allows
- Fc Fusion
- FcRn-mediated recycling prolongs circulation
- High increase
- High once established
- Programs requiring extended dosing intervals
- Albumin Fusion
- Fusion to albumin increases systemic persistence
- Large-molecule peptide constructs
- Formulation-Assisted Sustained Release
- Controlled release from depot or microsphere
- No molecular change
- Dependent on formulation design
- When molecular modification is constrained
