Vaccines, antibodies, and other top-selling therapeutics are biologics—complex biomolecules such as proteins and nucleic acids. Biomanufacturing these products involves lengthy and costly production, purification, and packaging processes. Not only are the final products complex, but the entire biomanufacturing process is complicated and sensitive, requiring the use of advanced instrumentation capable of sophisticated measurements to monitor the process and validate the final product.
Current measurements require contact with the biomanufacturing solution, which introduces additional sampling steps and a risk of contamination. Current quality control practices require opening a subset of vials from each batch and making conclusions about entire batches based on those measurements.
Yu's lab is pioneering the use of water proton nuclear magnetic resonance (wNMR) spectroscopy for biomanufacturing applications and has several issued and pending patents. First developed in 1946, NMR can be thought of as a laboratory MRI—a non-invasive measurement technique utilizing strong magnets. The Yu group uses benchtop, time-domain NMR instruments to measure characteristics of water that are sensitive to changes of the complex biomolecules dissolved in it. "Our goal is to apply these methods to measure important safety and efficacy factors of vaccines and drugs both during and after biomanufacturing," Yu explained.
For example, the team recently demonstrated sensitive, non-destructive measurements of concentration variability within intact insulin pens, as well as the ability to detect changes to packaged vaccines due to freezing, which can lead to decreased effectiveness. In another advance, Yu's team demonstrated the detection of variations in drug concentration and protein aggregation using wNMR under flow conditions that simulate a biomanufacturing system.
With support from NIIMBL, Yu's group, along with scientists from vaccine teams at Merck & Co. Inc. and Pfizer Inc., will adapt their flow wNMR methods to monitor the production and stability of vaccine-adjuvant complexes during biomanufacturing. The new FDA award will support development of additional wNMR-based methods to detect issues that arise during packaging, storage, and transport, such as variability of filling and freezing.
"Novel methods to improve process analytical technologies for vaccines and biologics are critical to the biopharmaceutical industry. I am pleased that IBBR researchers are working with industry and government agencies to develop innovative ways to address these challenges," said IBBR Director Dr. Thomas Fuerst.
IBBR is a joint research enterprise of the University of Maryland, College Park, the University of Maryland, Baltimore, and the National Institute of Standards and Technology. IBBR is also financially supported in part by the University of Maryland Strategic Partnership: MPowering the State, an initiative designed to achieve innovation and impact through collaboration. The Institute sits at the nexus of academic research and commercial application, bringing together critical elements necessary to inspire transformative discoveries in the field of biotechnology that provide innovative solutions to major scientific and engineering challenges important to society. IBBR researchers seek to advance the fields of disease pathways and biomolecular targets, biomolecular measurement sciences, and biomolecular engineering, including structure-based design of vaccines and therapeutics. The Institute also serves to expand the economic base of science and technology in the State of Maryland. For more information, visit https://www.ibbr.umd.edu/.
