Government support for pharmaceutical research and technology localization is further strengthening regional manufacturing capabilities. Rising demand for biologics in oncology and chronic disease treatment is expected to create significant opportunities for advanced excipient suppliers.
Emerging Trends
- Greater focus on excipient stability: The market is moving toward excipients that can maintain biological drug stability during storage and transport. This is important because proteins can lose quality under temperature, light, and environmental stress. ICH Q5C specifically addresses stability testing for biological and biotechnology products.
- Growing demand for high-quality surfactants: Polysorbate 20 and polysorbate 80 are widely used to protect therapeutic proteins from stresses that can cause instability. However, FDA research has shown that polysorbate degradation can contribute to particle formation, increasing interest in better-controlled and more stable surfactant systems.
- Increasing regulatory attention on excipient quality: Regulatory authorities are placing greater emphasis on the quality, safety, manufacturing process, and control of excipients. WHO issued good manufacturing practice guidance for pharmaceutical excipients in 2025, covering production, control, storage, and distribution.
- Development of excipients for advanced biologics: The expansion of monoclonal antibodies, bispecific antibodies, fusion proteins, cell therapies, and other advanced biological products is increasing formulation requirements. WHO identifies newer antibody formats and technologies as areas requiring appropriate quality, safety, and efficacy controls.
- More attention to patient-friendly formulations: Biologic developers are increasingly evaluating formulations according to the intended administration route and product characteristics. EMA guidance highlights the need to assess excipient composition, stability, particles, and formulation performance, supporting development of formulations suitable for practical patient administration.
Use Cases
- Stabilizing therapeutic proteins: Excipients are used to protect proteins from degradation, aggregation, and structural changes during manufacturing and storage. Buffers, sugars, amino acids, and surfactants can help maintain the required physical and chemical properties of therapeutic proteins.
- Preventing protein aggregation: Surfactants such as polysorbates can reduce unwanted interactions at air-liquid and other interfaces. This is particularly important for protein-based biologics because aggregation or particle formation can affect product quality and may require additional safety assessment.
- Supporting vaccine formulations: Excipients are used in vaccine formulations to support stability and maintain potency throughout storage. WHO states that biological preparations can be unstable and that formulation optimization is important from production through administration to the patient.
- Improving formulation and delivery: Some excipients can support drug delivery by improving formulation properties such as solubility, viscosity, stability, or absorption. FDA notes that excipients may improve drug delivery even though they are not intended to provide the primary therapeutic effect.
- Supporting advanced biologic products: Excipients are increasingly important in formulations containing monoclonal antibodies, antibody fragments, bispecific antibodies, fusion proteins, and other complex biological products. WHO guidance specifically covers these newer antibody-related products and their quality requirements.
