HYRIMOZ (adalimumab) is a biosimilar monoclonal antibody developed by Samsung Bioepis, targeting conditions like rheumatoid arthritis, psoriatic arthritis, and inflammatory bowel disease. Its formulation, including excipient composition, plays a crucial role in manufacturing stability, efficacy, safety, and market competitiveness.
Excipient Strategy for HYRIMOZ
Key aims of excipient selection:
- Maintain stability during manufacturing and storage.
- Ensure bioactivity of the monoclonal antibody.
- Minimize immunogenicity and adverse reactions.
- Optimize shelf life and ease of formulation scaling.
Common excipients in monoclonal antibody formulations:
- Sugars (e.g., sucrose, trehalose) to stabilize proteins during freeze-drying.
- Buffer agents (e.g., histidine, phosphate buffers) maintain stable pH.
- Surfactants (e.g., polysorbate 80) prevent aggregation.
- Amino acids (e.g., glycine) to enhance stability.
HYRIMOZ's specific excipient profile:
- Sugars: Sucrose, for stabilization during lyophilization.
- Buffer: Histidine buffer system, maintaining pH around 6.0–6.5.
- Detergent: Polysorbate 80, reducing surface adsorption and aggregation.
- Stabilizers: Sodium chloride, to maintain isotonicity.
- Packaging excipients: Presence of inert glasses and stoppers designed for compatibility with biological drugs.
Formulation considerations:
- Use of sucrose and trehalose improves stability during storage at various temperatures.
- Polysorbate 80 reduces aggregation risk but requires monitoring for leaching and oxidation.
- Buffer pH optimization (around 6.0–6.5) reduces degradation and immunogenicity risk.
- Lyophilized form extends shelf life, with excipients facilitating dry state stability.
