Innovative Surgical Practices Using Tissue-Based Regenerative Therapies May Be More Tightly Regulated

New FDA draft guidelines would place even tighter restrictions on surgical practice and may limit the development of new therapies.

The therapeutic use of human cell and tissue products is highly regulated by the U.S. government, but a specific exception allows surgeons to harvest, manipulate, and implant tissues in many commonly performed surgical procedures. While the operating room is often the stage where innovations in tissue engineering and regenerative medicine are realized, as surgeons use grafted tissues, novel biomaterials, and new approaches to numerous procedures including performing breast, chest and abdominal wall, and pelvic floor reconstruction, new FDA draft guidelines would place even tighter restrictions on surgical practice and may limit the development of new therapies. This topic is examined in an Editorial in Tissue Engineering, Part A, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free for download on the Tissue Engineering website until July 1, 2016. McGowan Institute for Regenerative Medicine faculty member J. Peter Rubin, MD, Chair of the Department of Plastic Surgery, UPMC Endowed Professor of Plastic Surgery, and Professor of Bioengineering at the University of Pittsburgh, is a co-author of the Editorial.

In the Editorial “Surgical Therapies and Tissue Regeneration: At the Intersection Between Innovation and Regulation,” the Clinical Council of the Editorial Board of Tissue Engineering discuss the United States Code of Federal Regulations as it relates to the use of human cells and tissues and the products derived from them (HCT/Ps). The authors describe the draft FDA regulatory guidance documents and how they would impact companies developing products for regenerative medicine and surgeons performing procedures on patients, including some unintended consequences on the practice of common reconstructive surgical procedures. Specifically they focus on the criteria that distinguish minimally manipulated HCT/Ps that are removed from and returned to the same patient in the operating room, as well as issues surrounding homologous use.

The other authors of the Editorial include Geoffrey Gurtner, MD, Stanford University School of Medicine (CA); Wei Liu, MD, PhD, Shanghai Jiao Tong University School of Medicine (China); Keith March, MD, PhD, Indiana University School of Medicine (Indianapolis); Riitta Seppänen-Kaijansinkko, MD, DDS, PhD, University of Helsinki (Finland); Michael Yaszemski, MD, PhD, Mayo Clinic College of Medicine (Rochester, MN); James Yoo, MD, PhD, Wake Forest University School of Medicine (Winston-Salem, NC).

“This important editorial raises critical questions regarding the latitude with which surgeons are able to care for patients in innovative ways,” says Co-Editor-in-Chief Peter C. Johnson, MD, Principal, MedSurgPI, LLC, and President and CEO, Scintellix, LLC, Raleigh, NC. “Tissue Engineering Clinical Council is taking part in discussions with the FDA to further clarify this emerging regulatory stance.” The editorial notes that “it will be important going forward for the FDA and clinicians in different specialties to work collaboratively to establish new regulatory pathways that facilitate the generation of new regenerative therapies that can help our patients, and also maintain patient safety. Additionally, harmonizing the FDA regulations with regulations in Europe and Asia will help standardize approaches across the globe. The FDA is continuing its focus on 21 CFR 1271 with another draft guidance document on homologous use recently released. Moreover, the FDA will be holding public hearings in 2016, and clinicians must have a voice. This is a true crossroads for innovative surgical practice, and the regulatory environment should evolve with new technologies.”
