In general, an unapproved medical device may be used only on human subjects when the device is under clinical investigation and when used by investigators participating in a clinical trial. However, there may be circumstances under which a health care provider may wish to use an unapproved device to save the life of a patient or to prevent irreversible morbidity when there exists no other alternative therapy. For investigational devices under an Investigational Device Exemption (IDE), the IDE regulation permits deviations from the investigational plan without prior approval when necessary to protect the life or physical well-being of a subject in an emergency. In such cases the health care provider should do their utmost to secure:
After emergency use, a detailed report should be made to FDA (if there is an IDE for the device) or CDRH or CBER (if there is not).
What if the situation is not an emergency? Can a patient with a serious illness or condition have access to an investigational device outside a study? Yes, FDA recognizes that there are circumstances in which an investigational device is the only option available for a patient faced with a life-threatening condition. Unlike emergency use of an unapproved device discussed above, prior FDA approval is needed before compassionate use occurs. Section 561(b) of the act and 21 CFR 812.35. In order to obtain agency approval, the sponsor should submit an IDE supplement requesting approval for a protocol deviation under section 812.35(a) in order to treat the patient. The IDE supplement should include:
The patient should not be treated until FDA approves the device’s use. The FDA will consider all the information above, along with preliminary evidence of safety and effectiveness. If the request is approved, the patient will be continuously monitored and a follow-up report must be submitted.
