Our Service Highlights Background FAQs Resource Quotation and Ordering

At Creative Biolabs, we are well aware of the challenges of biopharmaceutical development and the opportunities for non-IgG therapeutic antibody development. Our rich experience and expertise in pharmacokinetics/pharmacodynamics (PK/PD) evaluation and customized solutions will help you get the useful information you need about your therapeutic antibody. With the advent of novel technologies, considerable advances have been made at Creative Biolabs in terms of PK/PD evaluation.

Our Service

Non-IgG therapeutic antibodies and their conjugates demonstrate remarkable therapeutic potential due to their unique features, such as high selectivity and stability, specific targeting capabilities, and favorable anatomical site localization. At Creative Biolabs, we employ a comprehensive technical platform to conduct PK/PD evaluations immediately after antibody production, purification, and characterization. This approach ensures a deep understanding of their action-site exposure, target engagement, and pharmacological activity, ultimately enhancing the success of subsequent applications.

We provide PK/PD evaluations for therapeutic non-IgG antibodies supplied by clients or developed in-house. Our analyses utilize both model-dependent and model-independent methodologies, supported by a variety of animal models, including rodents, non-human primates, and dogs. Our platform is equipped to assess multiple PK/PD parameters, including but not limited to:

Antibody absorption and binding
Dose proportionality and distribution
Targeting and metabolism
Excretion and immunogenicity
Cross-species PK/PD translation
Human PK/PD prediction

We also integrate in vitro and in vivo data to develop frameworks for translating PK/PD properties from preclinical studies to human applications.

Background

PK is an approach of exploring the mechanism through which an organism affects a drug, while, PD aims to analyze the process that drug functions and affects the organism, both of which are of great importance in drug discovery and development, even in clinical applications. Therapeutic monoclonal antibodies (mAbs) are quite an important class of bioactive molecules with complex pharmacology and interdependent PK/PD properties. Compared to other small pharmaceutical molecules, mAbs have the advantages of high specificity, targeting, low side effects, etc. Definitely, the structures, unique characteristics, and function modes of mAbs make their PK/PD evaluations different, which are more complex. Additionally, non-IgG therapeutic antibodies are a new class of biomolecules with tremendous therapeutic potential against various diseases, especially for tumors. Compared to widely utilized monoclonal IgG antibodies, their PK/PD tests are similar but also different. Meanwhile, understanding the PK/PD of mAbs and their biological and mechanistic underpinnings is crucial to their design and selection, evaluating appropriate efficacy and toxicity studies, translating PK/PD parameters to humans, and optimizing dose and regimen to maximize success in the clinic.

FAQs

Q1: What is the importance of PK/PD evaluation in therapeutic antibody development?

A: PK/PD evaluation is essential for understanding how a therapeutic antibody interacts with the body (PK) and how it affects biological systems (PD). These insights are critical for optimizing antibody design, determining appropriate dosages, predicting clinical outcomes, and ensuring safety and efficacy.

Q2: How are non-IgG therapeutic antibodies different from IgG antibodies in PK/PD evaluation?

A: Non-IgG antibodies exhibit unique structural and functional properties, such as specific targeting and stability. While their PK/PD testing shares similarities with IgG antibodies, they require specialized methodologies to account for their distinct pharmacological behaviors and therapeutic potential.

Q3: What analytical methods are used for PK/PD evaluation?

A: PK/PD evaluations utilize advanced technologies such as ligand binding assays (LBA), enzyme-linked immunosorbent assays (ELISA), and electrochemiluminescence assays (ECLA) to measure antibody concentrations and analyze pharmacodynamic effects.

Q4: What types of animal models are used in preclinical PK/PD studies?

A: Preclinical evaluations involve various animal models, including rodents, non-human primates, and dogs. These models provide accurate insights into the antibody's pharmacological behavior and facilitate translational studies in humans.

Q5: What are the advantages of non-IgG therapeutic antibodies?

A: Non-IgG antibodies offer high selectivity, specificity, stability, and the ability to target specific anatomical sites, making them highly effective against diseases like cancer and other complex conditions.

Q6: Can PK/PD services be customized for specific research needs?

A: Yes, PK/PD evaluations are tailored to the unique requirements of each therapeutic antibody, including the development of custom assays and analytical methods specific to the antibody's characteristics.
