Nadine Ritter, Ph.D.

President and Analytical Advisor at Global Biotech Experts, LLC

Profile

Dr. Nadine Ritter is President and Analytical Advisor for Global Biotech Experts, LLC. She provides expertise in analytical test method selection and optimization for product characterization, release and stability testing; analytical test method qualification and validation, as well as pre- and post- approval product comparability studies, and assay bridging/technology transfers. In addition, she routinely performs third-party laboratory quality and compliance audits for small start-ups to multinational pharmaceutical corporations and contract testing laboratories.

She obtained her master and doctoral degrees in cell and molecular biology at Rice University (Houston, TX) on evolutionary mechanisms for subcellular translocation of mitochondrial proteins. She was engaged in basic academic research in the field of extracellular matrix proteins and the process of bone mineralization at the University of Texas Health Science Center in Houston for over 10 yrs. She entered the biopharm industry as a protein chemist in analytical R&D at Abbott Laboratories (Abbott Park, IL). There, she performed development, validation, transfer and troubleshooting of test methods for the analytical QC lab, generated protein characterization data for diagnostic product submissions, responded to FDA comments, and contributed to compliance remediation efforts for QC inspection observations, and lead the ISO9000 certification of the R&D analytical lab.

She then became the Director of the Analytical Services Division of BioReliance (Rockville, MD), a major contract testing organization. There, she led a team of CMC scientists in the design and conduct of method qualification, validation, and transfer, product characterization and comparability studies, and QC release and stability testing. Projects included synthetic peptides and oligonucleotides, natural and recombinant proteins, monoclonal and polyclonal antibodies, and viral particles. She managed quality and compliance activities for the R&D, GLP and GMP activities conducted in her lab, and implemented Part 11 computer system requirements. In 1999, she created the first public training course specifically focused on biotechnology stability programs, which later grew into an award-winning CMC analytical training course.

Since 2002, she has been an international consultant, trainer, speaker and writer for biotech and biosimilar products. She first worked independently at NMR Biotech Services (Germantown, MD), then in 2004 joined Biologics Consulting Group, Inc. (Alexandria, VA). In 2014, she decided to return to independent consulting, forming Global Biotech Experts, LLC. In 2003, she was one of six industry and two FDA founders of the CaSSS CMC Strategy Forum, which has led to the publication of major industry/regulatory white papers on CMC topics, and is now being held annually in North America, Europe, Asia and Latin America.
