Antibodies and antibody-conjugated therapies represent an important, rapidly growing area for the pharmaceutical and biotech industries. As these fields develop, there is an increasing need for analytical tools that provide detailed information about how these molecules behave in solution. Nuclear Magnetic Resonance (NMR) spectroscopy has a long and successful history in the pharmaceutical industry as a research tool, facilitating structural and dynamical studies of small molecules, peptides, oligonucleotides, and more. Over the past decade, NMR has been used to characterize the solution behavior and higher-order structural features of antibodies. Applying these techniques to antibody-conjugated therapies, many of which have challenging solution properties that diverge from those of their parent antibodies, has the potential to provide unique insight into structural and dynamic properties of these molecules.
In this webinar, we will describe novel applications of solution Nuclear Magnetic Resonance (NMR) spectroscopy to antibody-conjugated therapies to understand how conjugation impacts the higher-order structural features of antibodies. For this case study, antibodies were conjugated to two distinct linker-payload systems to probe the impact of specific payload classes on solution behavior. The drug-antibody ratio (DAR) was varied to further broaden the understanding of how conjugation influences the solution behavior of antibodies. Using NMR techniques that have previously been used to study antibodies, we generated fingerprint spectra of these antibody-drug conjugates, allowing direct visualization of structural changes as a function of payload, DAR, and time. These techniques have direct application as an analytical tool in the study of antibody higher-order structure and have the potential to allow for the development of novel therapies with improved solution properties.
