FDA experience – since 1994
Aric Kaiser, an expert biomedical engineer with experience in tissue mechanics and mechanical testing, has regulatory and scientific interests in the design and evaluation of products intended to treat orthopedic disorders. Of particular interest are tissue-engineered medical products (combination products) and devices intended to serve as functional replacements for the diseased or damaged tissue, e.g., products intended to repair/regrow damaged cartilage with functional tissue rather than implantation of synthetic materials as in total joint replacements. Recent work has focused on bone void fillers containing calcium salts, collagen and/or recombinant human proteins or synthetic peptides.
Proposed Regulatory Research Project for the FDA Commissioner's Fellow:
The Division of Orthopaedic Devices has seen an increase in the number of applications for bone void fillers used in a variety of orthopedic applications over the last several years. The complexity of these fillers, particularly those incorporating recombinant human proteins/synthetic peptides or modified manufacturing methods, would be enhanced by a review and production of a “lessons learned” and/or minimum non-clinical evaluation document based on recent applications. An example would be identification of the evaluations necessary to differentiate devices that have identical chemistry, e.g., calcium phosphate, but different final characteristics, e.g., surface topography or surface charge. In addition to these types of general documents, a guidance document describing the requirements for submissions investigating fracture healing would also be very useful to agency staff and industry.
The fellow would also participate in reviews of pre-IDEs, IDEs, 510(k)s and PMAs on these products and interact with staff from other review groups for products with dental and orthopedic uses, from OSB concerning post-market issues, as well as staff from CDER, CBER and CVM concerning pre- and post-market issues associated with these products.
FDA Fellows participating in this program will learn the basic science, regulatory science and review processes associated with the regulation of bone void fillers (with and without recombinant human proteins or synthetic peptides.) The project will include an evaluation of past applications and clearances/approvals to look for commonly resolved issues, tests and clinical study design in order to provide background for new guidance documents or other internal/external communications within FDA and with industry.
The applicant should have a Ph.D. or M.S. (with at least 3 years of research experience) in an appropriate engineering (biomedical, chemical, materials or mechanical) or scientific discipline with experience in bone biology/chemistry, tissue engineering, regenerative medicine and non-clinical testing of biological materials.
