PRP Regulation: How is Platelet-Rich Plasma Regulated by the FDA?

Platelet-Rich Plasma (“PRP”) has become a popular treatment for various conditions from sports injuries to hair rejuvenation so it makes sense that PRP regulation must keep up.  With PRP, both the device used to separate platelets and the subsequent use of the PRP product fall under the scope of the U.S. Food and Drug Administration (“FDA”).  The common question is: what is approved by the FDA with regards to PRP?  Given the increased use, it is important for health care providers to understand the FDA’s standpoint on PRP regulation.

Medical Device Regulation

Let’s start with PRP devices.  Generally, the FDA provides several avenues in which a device, drug, or biologic can come to market.  For medical devices, an applicant can either obtain Premarket Approval (“PMA”) or 510(k) clearance.  Most PRP preparation systems have utilized the 510(k) clearance process.  What is meant by 510(k) clearance?  The 510(k) application process, also known as premarket notification (“PMN”), is for medical devices that are seen as lower risk which are found to be “substantially equivalent” to a previously cleared device.  Under the Food, Drug and Cosmetic Act, device manufacturers are required to register and notify the FDA of the intent to market a medical device in advance.

The FDA then determines whether the device is equivalent to a device already on the market.  The 510(k) clearance process is a common way for PRP devices because it is less costly and time consuming as opposed to obtaining PMA.  There is one important caveat though with 510(k) clearance.  Clearance does not equate to approval for treatment of any indication.  It only applies to its intended use in a specific setting.  For example, in past warning letters issued by the FDA, the agency has required certain manufacturers to add language to its label stating that the PRP prepared by the device had not been evaluated for any clinical indication.  

PRP Regulation – Off Label Use

Unless approved for a particular indication, any use of PRP outside of the intended setting is considered “off label use.”  This use, however, is not prohibited by the FDA PRP regulation if conducted by a physician with the intent to practice medicine.  According to FDA guidance issued to agency institutional review boards and investigators, physicians who use a product for an indication not approved on the labeling have the “responsibility to be well informed about the product, to base its use on firm scientific rationale and on sound medical evidence, and to maintain records of the product’s use and effects.”  The guidance further states that when the intent to practice medicine is present, the submission of an investigational new drug application (“IND”), investigational device exemption (“IDE”), or review by a board is not required.

At this time, it is clear that the FDA will not regulate the practice of medicine as long as certain responsibilities are met.  However, health care providers utilizing PRP should be mindful of the heightened regulatory environment and continue to stay informed.
