In the ever-evolving landscape of pharmaceuticals, advancements in science have led to a shift in the types of therapeutic molecules being developed. Gone are the days of solely relying on small-molecule drugs and monoclonal antibodies. Instead, the emergence of mRNA therapies, antisense oligonucleotide treatments, and gene therapies has opened up new horizons for treating complex diseases. As we dive deeper into the realm of cell and gene therapy, pharmacokinetics (PK) and flow cytometry have become pivotal players in this transformative journey.
A Changing Industry: The Rise of Cell and Gene Therapies
Traditionally, drug development centered around small molecule and monoclonal antibody drugs, which targeted specific pathways or proteins. While effective, these treatments often had a longer production life and development process. Recently, however, the industry has witnessed a surge in mRNA therapies, gene replacement therapies, and modification therapies designed to address specific diseases like Duchenne’s muscular dystrophy, type one diabetes, and hemophilia, for example.
Within the realm of cell and gene therapy, approaches like Chimeric Antigen Receptor T-cell (CAR T) therapies are gaining prominence. These treatments involve extracting patient cells, modifying them, and reintroducing them to the patient to combat diseases like immuno-oncology disorders. As the cell itself becomes the drug, the complexity of measuring pharmacokinetics increases exponentially.
As we delve deeper into the realm of cell and gene therapies, the need for robust pharmacokinetic mechanisms becomes paramount. Here’s where flow cytometry, once primarily used for pharmacodynamic assays, steps into the spotlight. Flow cytometry, with its ability to identify and enumerate cells, has become a critical tool in the pharmacokinetic arsenal.
Where traditional pharmacokinetics assessed the concentration of drugs in the body, with cell therapies, it’s about quantifying and understanding the survival, proliferation, and effects of the modified cells within the patient. Flow cytometry allows us to track and analyze these changes, offering invaluable insights into the therapy’s performance.
Challenges and Agilex’s Expertise
While flow cytometry proves indispensable, developing and validating these assays present challenges. Since flow cytometry assays are quasi-qualitative, validation according to the latest guidelines becomes a crucial aspect. At Agilex, we’ve proactively tackled these challenges head-on.
Our team of experienced scientists has attended workshops and discussions on cell and gene therapy programs, flow cytometry assays, and validation. We’re well-equipped to develop and validate assays for various disease indications, allowing us to identify and quantify CAR T cell populations and perform broad immunophenotyping, activation assays, and intracellular staining assays.
If you’re a small to medium biotech company working on a cell and gene therapy product, you’re likely facing the challenge of assaying and quantifying your modified cells within patient populations. Agilex offers the confidence and expertise needed to develop customized flow cytometry assays tailored to your specific requirements.
