Large Molecule PK/BA Services

Creative Animodel has a brilliant history of providing the large molecule Pharmacokinetics (PK) and bioanalysis (BA) service with adherence to GLP regulations to advance the pharmaceutical industries. Equipped with the state-of-the-art technical platforms, our studies are performed by an innovative expert team that ensures consistent, high-quality, and on-budget data, with a fast turnaround time.

Large molecule drugs, referred to as biologics, are protein-based drugs, which are manufactured in living cells or contain components of living organisms by biotechnology, while the traditional small-molecule drugs are often manufactured via chemical synthesis. As the most advanced therapies available, biologics have been widely applied to treatment of numerous diseases and conditions, especially those hard-to-treat ones, like cancer.

Why Do We Highlight Large Molecule PK/BA Services?

Large molecules are different from small molecules in many aspects, such as size, behavior, mode of action, suitability for certain drug forms and manufacturing process, etc. Compared to small molecule drugs, large molecule drugs require approximately five times of quality assurance tests to ensure purity, potency, and quality. Because with a more complex structure, large molecules are often hundreds of times the size of small molecules, which are highly sensitive to temperature and pH, and susceptible to minor changes of conditions, likely leading to an increased risk of unexpected immune responses. All these factors drive the special concerns for large molecule PK/BA services.

Apart from this, the distinctive ADME characteristics of large molecules also highlight the need for ADME characterization and safety-related studies in drug development of biologics.
