BioAgilytix understands that when it comes to pharmacokinetic (PK) assays, it is of highest priority that the applied bioanalytical method is well characterized, fully validated, and documented in order to yield reliable results. We offer high-quality PK assay procedures and results strictly in compliance with GLP / GMP regulations and in accordance with international regulatory standards (FDA, EMEA, ICH).

Pharmacokinetics (PK) describes what the human body does to a given pharmaceutical, from the time of administration to absorption, distribution, metabolism, and excretion from the body. By assessing PK of a biological drug in different matrices, including serum, plasma, urine, and saliva, we can understand a drug’s interaction with the body, as well as the intensity and duration of its efficacy.
Understanding the pharmacokinetic behavior of a given therapeutic drug is an essential element of understanding its effectiveness and safety, as well as identifying the proper dosage and distribution. As such, PK assays are a vital component of the drug development process, and the data derived is used to help select dosage for preclinical and clinical studies. The Federal Drug Administration (FDA) has also issued extensive industry guidance on measuring Population Pharmacokinetics (PK).

See recommendations from the AAPS Biosimilars Action Program Committee (APC) for the development and validation of LBAs to support PK assessments for biosimilar drug development.
Our scientists are experienced in supporting PK assessments in a variety of species including rodents, humans, and non-human primates, and in multiple matrices such as serum, plasma, urine, and saliva. We are well-versed in the factors that could influence the validity of the data generated by these assays, and take those complexities into account during method validation to ensure optimal results. Our team has a clear understanding of the ability of the assay to detect the drug in the sample matrix.
In addition to their use for the detection of monoclonal antibodies using anti-idiotypic antibodies, BioAgilytix establishes and validates PK assays for therapeutic proteins with endogenous counterparts. PK assays are also required for comparative analysis of originator and biosimilar products, which our team is well-versed in performing.
We conduct our high-quality PK assay procedures and results strictly in compliance with GLP / GMP regulations and in accordance with international regulatory standards (FDA, EMEA, ICH).
There are several analytical technologies that can be used for PK analysis. BioAgilytix will help you select the best-fit platform for your project, based on both sensitivity and regulatory requirements. We have extensive experience developing and validating assays to evaluate pharmacokinetic behavior throughout the phases of the drug development process using the platforms listed below.
