For Immediate Release: January 28, 2020
This is a pivotal time in the field of gene therapy as the FDA continues its efforts to support innovators developing new medical products for Americans and others around the world. To date, the FDA has approved four gene therapy products, which insert new genetic material into a patients cells. The agency anticipates many more approvals in the coming years, as evidenced by the more than 900 investigational new drug (IND) applications for ongoing clinical studies in this area. The FDA believes this will provide patients and providers with increased therapeutic choices.
In that spirit, today, the FDA is announcing the release of a number of important policies: six final guidances on gene therapy manufacturing and clinical development of products and a draft guidance, Interpreting Sameness of Gene Therapy Products Under the Orphan Drug Regulations.
The growth of innovative research and product development in the field of gene therapy is exciting to us as physicians, scientists and regulators, said FDA Commissioner Stephen M. Hahn, M.D. We understand and appreciate the tremendous impact that gene therapies can have on patients by potentially reversing the debilitating trajectory of diseases. These therapies, once only conceptual, are rapidly becoming a therapeutic reality for an increasing number of patients with a wide range of diseases, including rare genetic disorders and autoimmune diseases.
As the regulators of these novel therapies, we know that the framework we construct for product development and review will set the stage for continued advancement of this cutting-edge field and further enable innovators to safely develop effective therapies for many diseases with unmet medical needs, said Peter Marks, M.D., Ph.D., director of the FDAs Center for Biologics Evaluation and Research. Scientific development in this area is fast-paced, complex, and poses many unique questions during a product review; including how these products work, how to administer them safely, and whether they will continue to achieve a therapeutic effect in the body without causing adverse side effects over a long period of time.
One of the most important steps the FDA can take to support safe innovation in this field is to create policies that provide product developers with meaningful guidance to answer critical questions as they research and design their gene therapy products.
The six final guidances issued today provide the agencys recommendations for product developers on manufacturing issues and recommendations for those focusing on gene therapy products to address specific disease areas. The six guidance documents incorporate input from many stakeholders and take a significant step toward helping to shape the modern structure for the development and manufacture of gene therapies. The agency is issuing this suite of documents to help advance the field of gene therapy while providing recommendations to help ensure that these innovative products meet the FDAs standards for safety and effectiveness.
The scientific review of gene therapies includes the need to evaluate highly complex information on product manufacturing and quality. In addition, the clinical review of these products frequently poses more challenging questions to regulators than reviews of more conventional drugs, such as questions about the durability of response, and these questions often cant be fully answered in pre-market trials of reasonable size and duration. For some gene therapy products, therefore, although they have met the FDAs standards for approval, we may need to accept some level of uncertainty around questions of the duration of the response at the time of marketing authorization. Effective tools for reliable post-market follow up, such as post-market clinical trials, are going to be key to advancing this field and helping to ensure that our approach fosters safe and innovative treatments.
The draft guidance on interpreting sameness of gene therapy products under the orphan drug regulations provides the FDAs proposed current thinking on an interpretation of sameness between gene therapy products for the purposes of obtaining orphan-drug designation and eligibility for orphan-drug exclusivity. The draft guidance focuses on how the FDA will evaluate differences between gene therapy products when they are intended to treat the same disease. As laid out in the draft guidance and our regulations, the agencys determination will consider the principal molecular structural features of the gene therapy products, which includes transgenes (the transferred gene) and vectors (the vehicle for delivering the transgene to a cell).
With the large volume of products currently being studied, gene therapy product developers have asked the agency important questions about orphan-drug designation incentives to develop products for rare diseases with very small patient populations. The draft guidance has potential positive implications both for product developers and patients by providing insight into the agencys most current thinking on the sameness of products, and thus, not discourage the development of multiple gene therapy products to treat the same disease or condition. For patients, this policy could help lead to the development and approval of multiple treatments, creating a more competitive market with choices. We encourage stakeholders to provide their comments.
In sum, these policy documents are representative of efforts to help advance product development in the field of gene therapy. We will continue to work with product innovators, sponsors, researchers, patients, and other stakeholders to help make the development and review of these products more efficient, while putting in place the regulatory controls needed to ensure that the resulting therapies are both safe and effective. We also encourage developers of new gene therapy products to make full use of our expedited programs available for products intended to address unmet medical needs in the treatment of serious or life-threatening conditions. These programs include breakthrough therapy designation, regenerative medicine advanced therapy designation, and fast track designation, as well as priority review and accelerated approval. Developers should pursue these programs whenever possible to help bring the benefits of important advances to patients as soon as possible. We believe our work will help advance innovations in a way that assures their safety and effectiveness, provides new therapeutic choices to patients and providers and continues to build confidence in this novel and emerging area of medicine.
The FDA is an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nations food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.
