What we do
About our project
In oncology, monoclonal antibodies (mABs) have become key players. Still, their pharmacokinetics (PK) are largely unexplained. Since PK might predict for treatment outcome or toxicity, we aim to map the PK of mABs and factors that influence it.
ObjectiveTo set up a bank of prospectively collected blood samples for pharmacokinetic analyses of monoclonal antibodies.
Study design: Prior to every cycle and until the next treatment line a blood sample for pharmacokinetic analyses will be withdrawn. Optionally, additional blood samples will be withdrawn in the first week after the first treatment cycle.
Study populationAdult patients planned to receive a monoclonal antibody as anti-cancer treatment.
Main study parameters/endpointsThe primary study endpoint is the trough level of different monoclonal antibodies over time. Secondary endpoints include the quantity of antibodies against the therapeutic monoclonal antibody and intrinsic characteristics of peripheral blood immune cells (in PBMC).
Our research focus
- To set up a bank of prospectively collected blood samples from patients treated with monoclonal antibodies.
- To correlate pharmacokinetic (PK) parameters with effectiveness and toxicity of monoclonal antibodies.
- To determine the influence of immunogenicity on PK.
- To determine the influence of peripheral blood immune cell characteristics on PK and effectiveness and toxicity of monoclonal antibodies.
- Explore the characteristics of exosomes before start of treatment, during treatment, and after disease progression.
- To assess the course of PK and peripheral mononuclear blood cells characteristics shortly after the first treatment cycle, i.e. within 1 week.
- To validate an assay that can determine serum concentrations of monoclonal antibodies.
