Follow-on Biologics Workshop

Follow-on Biologics Workshop
Reported by
Angelo DePalma

Posted July 01, 2009

Presented By

New York Academy of Sciences and the U.S. Food and Drug Administration, in collaboration with the National Institute of Standards and Technology (NIST)


The New York Academy of Sciences, in conjunction with the FDA and the National Institute for Standards and Technology (NIST), held a workshop on December 12–14, 2005 that focused on the scientific issues involved in assessing the similarity of follow-on protein products. At the conference, scientists from academe, industry, and government surveyed the scientific issues surrounding protein structure and function, focusing on specific analytical methodologies for characterizing protein products.

The first half of the conference focused on the challenges posed by the complexities of protein structure. Day one covered primary, secondary, and tertiary structure, and analytical methods for characterizing those structures. On the first half of day two, speakers discussed quaternary structure, protein-protein interactions, and protein aggregates. Speakers from FDA and NIST introduced these sessions, laying out the scientific and regulatory challenges presented by each protein structure element. During the second half of day two, several speakers discussed the impact of processing on protein properties.

Barry Cherney is deputy director at the division of therapeutic proteins in the office of biotechnology products at FDA's Center for Drugs Evaluation and Research (CDER). His regulatory duties have included oversight of reviews for INDs and BLAs for recombinant and naturally derived proteins, product reviewer training, and development of regulatory guidance to address scientific issues related to characterization, manufacture, and control of specified and naturally derived protein products.

Cherney obtained his PhD in biology from Case Western Reserve University. His dissertation work involved the purification and characterization of the nuclear enzyme, Poly (ADP-ribose) synthetase. In 1986, he began postdoctoral training in the department of biochemistry and molecular biology at Georgetown University where he worked on molecular approaches toward defining the structure/function of this enzyme. He joined CBER in 1991 as a senior staff fellow in the division of hematological products and in addition to his regulatory duties, conducted research on the molecular mechanisms leading to tumorigenesis. Since 1998, Cherney has held positions as a full time regulatory reviewer, an expert biologist and became deputy director of the division of therapeutic proteins in March 2001. He was FDA's topic lead expert on ICH Q5E for comparability of biotech products and has been involved with issues concerning the comparison of protein products throughout his FDA career.

Curtis Meuse, PhD

National Institute of Standards and Technology

Curtis Meuse is a scientist in the biochemical science division of Chemical Science and Technology Laboratory at the National Institute of Standards and Technology (NIST). He received his PhD in chemistry at the University of Massachusetts, Amherst studying ultra-thin polymer layers using infrared spectroscopy. As a postdoctoral fellow in the Laboratory of Chemical Physics at the National Institutes of Health, he synthesized specifically fluorinated phospholipids and studied their nano-domain structure using Raman spectroscopy. In 1995, he was hired as part of a NIST-wide initiative to develop expertise in the development and characterization of new biomimetic materials. In the Biomolecular Materials Group, he developed methods and models for the characterization of the molecular structure of cell membrane components organized on surfaces using neutron reflectivity and optical techniques. In addition, a state-of-the-art infrared spectroscopic ellipsometer was built and methods for the analysis of spectroscopic data to determine the thickness, optical constants and molecular structure of various cell monolayer and bilayer constructs were developed.

Currently in the biospectroscopy group, Meuse’s work is focused on protein conformation measurements. The goals of his work are to develop and standardize methods to characterize the biologically active state, to allow the measurement of structural changes, and to characterize physical processes that contribute to biological inactivation of proteins such as aggregation and macromolecular association/dissociation. For example, infrared methods have been developed to quantify protein structural stability and protein binding interactions by quantifying the extent of the exchange of deuterium for hydrogen in the amide bonds of proteins in solutions, as solids, in membranes or immobilized on surfaces. In addition, collaborations with the United Kingdom’s National Physics Laboratory are underway on a pilot study for the standardization of biomolecular circular dichroism measurements under the auspices of the International Committee for Weights and Measures.

Emily Shacter is chief of the laboratory of biochemistry in the division of therapeutic proteins of the Office of Biotechnology Products, Office of Pharmaceutical Science, CDER. She received her PhD in biochemistry from Johns Hopkins University in 1982, carried out basic cell regulation and cancer research at the National Institutes of Health for 12 years, and then joined the FDA in 1994.

Shacter oversees the review of INDs and BLAs for novel therapeutic proteins covering a wide range of clinical indications, including cancer, hematopoiesis, tissue repair and remodeling, thrombosis and thrombolysis, inflammatory disease, and bioterrorism. She is engaged in establishing CDER policy regarding product manufacture and characterization and performs inspections of biotechnology manufacturing facilities.

Shacter also runs an active laboratory research program to support the scientific review of therapeutic proteins that have wide-ranging mechanisms of action and unique biological and physicochemical characteristics. Her laboratory research focuses on studying the cytotoxic mechanisms of cancer chemotherapy drugs and understanding how elements of the immune system, such as oxidants and activated phagocytes, influence killing and clearance of dying cells. Her research expertise in the area of protein oxidation is applied regularly to the review of protein therapeutics.
