For general information on expanded access for medical products, see the FDA’s Expanded Access page.

***Expanded access***is a potential pathway for patients with a serious or life-threatening disease or condition to access an investigational medical device that has not been approved or cleared by the FDA for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available through one of three mechanisms:

Emergency Use
	Compassionate Use (or Individual Patient/Small Group Access)
	Treatment Investigational Device Exemption (IDE)This page is intended to help health care providers and device manufacturers learn about expanded access options for medical devices and associated criteria and requirements for each.

For information on the number of expanded access requests CDRH receives and approves on a yearly basis, refer to the Expanded Access Submission Data page.

Emergency Use

What is Emergency Use?

Emergency use is when there is a need to use a device that has not received the FDA’s approval or clearance in an emergency. Expanded access to an investigational device under the emergency use mechanism is intended to provide patients and physicians with access to investigational devices to address immediately life-threatening situations when there is no available alternative and no time to use existing procedures to obtain FDA approval.  Emergency use may apply if the device is being studied in clinical trials under an investigational device exemption (IDE) such as when a physician who is not part of the IDE clinical study wishes to use the device to treat a patient in an immediately life-threatening situation. An IDE allows an investigational device to be used in a clinical study in order to collect safety and effectiveness data.  Emergency use may also apply if there is no IDE or ongoing clinical studies for the device.

Criteria for Emergency Use

The patient has a life-threatening condition that needs immediate treatment;
	No generally acceptable alternative treatment for the condition exists; and
	Because of the immediate need to use the device, there is no time to use existing procedures to obtain FDA approval for the use.Is FDA approval required prior to Emergency Use?

No. If all of the above criteria are met, an unapproved device may be used in an emergency situation without prior approval by the FDA.

The FDA expects the physician to make the determination that the patient's circumstances meet the above criteria, to assess the potential for benefit from the use of the unapproved device, and to have substantial reason to believe that benefits will exist. In the event that a device is used in circumstances meeting the criteria listed above, the physician should follow as many patient protection procedures as possible. Such patient protection procedures include obtaining:

Informed consent from the patient or a legal representative;
	Clearance from the institution as specified by their policies;
	Concurrence of the Institutional Review Board (IRB) chairperson;
	An independent assessment from an uninvolved physician; and
	Authorization from the device manufacturer.Do I need to report Emergency Use to the FDA?

Yes. If there is an IDE for the device, the IDE sponsor must notify the FDA of the emergency use within 5 days through submission of an IDE Report (§812.35(a)(2)). This follow-up report should include a summary of the conditions constituting the emergency, the patient protection measures that were followed, and patient outcome information.

If no IDE exists, the physician should submit to the FDA a follow-up report within 5 days on the use of the device including: a description of device used, details of the case, and the patient protection measures that were followed.  The report should be submitted to:

Food and Drug Administration
Center for Devices and Radiological Health
10903 New Hampshire Ave
Document Control Center
WO66 Rm G-609
Silver Spring, MD 20993

Compassionate Use (or Individual Patient/Small Group Access)

What is Compassionate Use?

The FDA recognizes that there are circumstances in which an investigational device is the only option available for a patient faced with a serious or life-threatening disease or condition.

The compassionate use provision provides a path to accessing investigational devices that have not received FDA approval or clearance for patients for whom the treating physician believes the device may provide a benefit in diagnosing, monitoring, or treating their disease or condition. Compassionate use can be for devices that are being studied in a clinical trial under an IDE for patients who do not meet the requirements for inclusion in the clinical investigation but for whom the treating physician believes the device may provide a benefit in treating or diagnosing their disease or condition. It can also be used for devices that are not being studied in a clinical investigation (such as an IDE for the device does not exist). This provision is typically approved for individual patients but may be approved to treat a small group, if the small group request is under an IDE.

Criteria for Compassionate Use

The patient has a life-threatening or serious disease or condition;
	There is no comparable or satisfactory alternative therapy to diagnose, monitor, or treat the disease or condition; and
	Potential patient benefit justifies the potential risks of the investigational device.Is FDA approval required prior to Compassionate Use?

Yes. Prior FDA approval is needed before compassionate use occurs.

How do I request approval for Compassionate Use of a device?

If a licensed physician would like to obtain an investigational device for an individual patient, the medical device company must first agree to provide the investigational device for compassionate use. The FDA cannot require a company to provide an investigational device for compassionate use to proceed. If the device manufacturer agrees to provide the device under compassionate use, there are two different processes to follow to obtain FDA approval, depending on whether or not there is an IDE for a clinical trial for that device.

If there is an IDE for the device

The IDE sponsor (who may be the device manufacturer or a physician who has submitted the IDE to conduct the clinical study for the device) should submit an IDE supplement requesting approval for a compassionate use under section §812.35(a) to treat the patient. The IDE supplement should include:

A description of the patient's condition and the circumstances necessitating treatment;
	A discussion of why alternative therapies are unsatisfactory and why the probable risk of using the investigational device is no greater than the probable risk from the disease or condition;
	An identification of any deviations in the approved clinical protocol that may be needed to treat the patient;
	The patient protection measures that will be followed:
	A draft of the informed consent document that will be used;
		Clearance from the institution as specified by their policies;
		Concurrence of the IRB chairperson;
		An independent assessment from an uninvolved physician; and
		Authorization from the device manufacturer on the use of the device.In some cases, the Institutional Review Board (IRB) will not approve the request until they have approval from the FDA. In such cases, the original request should indicate IRB approval will be obtained prior to use of the device. Proof of the approval by the IRB Chairperson will need to be submitted with the follow-up report after the patient is treated. The physician should ask the IRB or risk management staff if institutional clearance is needed in addition to the IRB Chair concurrence.

The above compassionate use criteria and procedures can also be applied when a physician wishes to treat a few patients rather than an individual patient suffering from a serious disease or condition for which no alternative therapy adequately meets the patient’s medical need. In this case, the IDE supplement should include the information identified above and indicate the number of patients to be treated. The supplement should also include the protocol to be followed or should identify deviations from the approved clinical protocol. As with single patient compassionate use, a monitoring schedule should be designed to meet the needs of the patients while recognizing the investigational nature of the device. Follow-up information on the use of the device should be submitted in a report after all compassionate use patients have been treated.

If there is no IDE for the device

A compassionate use request for a single patient may be submitted by the physician or manufacturer with the above information to the FDA, along with a description of the device provided by the manufacturer, to the following address:

Food and Drug Administration
Center for Devices and Radiological Health
10903 New Hampshire Ave
Document Control Center
WO66 Rm G-609
Silver Spring, MD 20993

Physicians and manufacturers can contact CDRHExpandedAccess@fda.hhs.gov for assistance.

The physician should not treat the patient identified in the request until the FDA approves use of the device under the proposed circumstances. In reviewing this type of request, the FDA will consider the above information as well as whether the preliminary evidence of safety and effectiveness justifies such use and whether such use would interfere with the conduct of a clinical trial to support marketing approval.

If the request is approved, the attending physician should devise an appropriate schedule for monitoring the patient, taking into consideration the investigational nature of the device and the specific needs of the patient. The patient should be monitored to detect any possible problems arising from the use of the device.

What actions does the FDA take on Compassionate Use requests?

After a compassionate use request is received, the FDA will either approve, approve with conditions, or disapprove the request. When there is an IDE for the device, compassionate use request IDE supplements have the same statutory 30-day review cycle as other IDE submissions. However, the patient need is considered when reviewing these requests.

Compassionate use requests are reviewed, on average, within 15 days of receipt, and in as little as one day in some cases.  An external assessment of the Expanded Access Program was completed in 2018. For details, see Expanded Access Program Report (PDF - 674 KB).

Do I need to report anything to the FDA after the Compassionate Use occurs?

Yes. Following the compassionate use of the device, a follow-up report should be submitted by whoever submitted the original compassionate use request to the FDA within 45 days of using the investigational device. This report should present summary information regarding patient outcome. If any problems occurred as a result of device use, these should be discussed in the follow-up report and reported to the reviewing IRB as soon as possible.

Treatment Investigational Device Exemption (IDE)

What is a Treatment IDE?

An approved IDE specifies the maximum number of clinical sites and the maximum number of human subjects that may be enrolled in the study. During the course of the clinical trial, if the data suggest that the device is effective, then the trial may be expanded under a new IDE to include additional patients with life-threatening or serious diseases. This is called a treatment IDE.

Criteria for a Treatment IDE

The device is intended to treat or diagnose a serious or immediately life-threatening disease or condition;
	There is no comparable or satisfactory alternative device available to treat or diagnose the disease or condition in the intended patient population;
	The device is under investigation in a controlled clinical trial for the same use under an approved IDE, or all clinical trials have been completed; and
	The sponsor of the controlled clinical trial is pursuing marketing approval or clearance of the investigational device with due diligence.A device that is not approved for marketing may be under clinical investigation for a serious or immediately life-threatening disease or condition in patients for whom no comparable or satisfactory alternative device or other therapy is available. During the clinical trial or prior to final action on the marketing application, it may be appropriate to use the device in the treatment of patients not in the trial under the provisions of the treatment investigational device exemption (IDE) regulations. (§812.36)

The treatment IDE facilitates the availability of promising new devices to desperately ill patients as early in the device development process as possible, before general marketing begins, and to obtain additional data on the device's safety and effectiveness. In the case of a serious disease, a device ordinarily may be made available for treatment use under this section after all clinical trials have been completed. In the case of an immediately life-threatening disease, a device may be made available for treatment use under this section prior to the completion of all clinical trials.

An "immediately life-threatening" disease means a stage of a disease in which there is a reasonable likelihood that death will occur within a matter of months or in which premature death is likely without early treatment. A Treatment IDE may also be used for investigational devices intended for diagnostic purposes.

How does a sponsor apply for a Treatment IDE?

A treatment IDE application must include, in the following order:

The name, address, and telephone number of the sponsor of the treatment IDE;
	The intended use of the device, the criteria for patient selection, and a written protocol describing the treatment use;
	An explanation of the rationale for use of the device, including, as appropriate, either a list of the available regimens that ordinarily should be tried before using the investigational device or an explanation of why the use of the investigational device is preferable to the use of available marketed treatments;
	A description of clinical procedures, laboratory tests, or other measures that will be used to evaluate the effects of the device and to minimize risk;
	Written procedures for monitoring the treatment use and the name and address of the monitor;
	Instructions for use for the device and all other labeling as required under section §812.5(a) and (b);
	Information that is relevant to the safety and effectiveness of the device for the intended treatment use. Information from other IDEs may be incorporated by reference to support the treatment use;
	A statement of the sponsor's commitment to meet all applicable responsibilities under the IDE regulations (21 CFR 812) and Institutional Review Boards regulations (21 CFR 56) and to ensure compliance of all participating investigators with the informed consent requirements of 21 CFR 50;
	An example of the agreement to be signed by all investigators participating in the treatment IDE and certification that no investigator will be added to the treatment IDE before the agreement is signed; and
	If the device is to be sold, the price to be charged and a statement indicating that the price is based on manufacturing and handling costs only.A licensed physician who receives an investigational device for treatment use under a treatment IDE is an "investigator" under the IDE and is responsible for meeting all applicable investigator responsibilities under 21 CFR 812, 21 CFR 50, and 21 CFR 56.

Applications should be identified on the outside envelope as a treatment IDE application and reference the IDE number. The original and two copies should be mailed to the following address:

Food and Drug Administration
Center for Devices and Radiological Health
Document Mail Center - WO66-G609
10903 New Hampshire Avenue
Silver Spring, MD 20993-0002

What are FDA actions on Treatment IDE applications?

*Approval of treatment IDEs*

Treatment use under a treatment IDE may begin 30 days after the FDA receives the treatment IDE submission. The FDA may notify the sponsor in writing earlier than the 30 days that the treatment use may or may not begin. The FDA may approve the treatment use as proposed or approve it with modifications.

*Disapproval or withdrawal of approval of treatment IDEs*

The FDA may disapprove or withdraw approval of a treatment IDE if:

The required criteria [§812.36(b)] are not met or the treatment IDE application does not contain the required information [§812.36(c)];
	The FDA determines that any of the grounds for disapproval or withdrawal of approval apply [§812.30(b)(1) through (b)(5)]. See FDA Action on IDE Applications, for additional information;
	The device is intended for a serious disease or condition and there is insufficient evidence of safety and effectiveness to support such use;
	The device is intended for an immediately life-threatening disease or condition and the available scientific evidence, taken as a whole, fails to provide a reasonable basis for concluding that the device:
	may be effective for its intended use in its intended population; or
		would not expose the patients to whom the device is to be administered to an unreasonable and significant additional risk of illness or injury;
	There is reasonable evidence that the treatment use is impeding enrollment in, or otherwise interfering with the conduct or completion of, a controlled investigation of the same or another investigational device;
	The device has received marketing approval or clearance, or a comparable device or therapy becomes available to treat or diagnose the same indication in the same patient population for which the investigational device is being used;
	The sponsor of the controlled clinical trial is not pursuing marketing approval or clearance with due diligence;
	Approval of the IDE for the controlled clinical investigation of the device has been withdrawn; or
	The clinical investigator(s) named in the treatment IDE are not qualified by reason of their scientific training and/or experience to use the investigational device for the intended treatment use.Safeguards

Treatment use of an investigational device under a treatment IDE is conditioned upon the sponsor and investigators complying with the safeguards of the IDE process and the regulations governing informed consent (21 CFR 50) and institutional review boards (21 CFR 56).

What are the reporting requirements for a Treatment IDE?

The sponsor of a treatment IDE must submit progress reports on a semi-annual basis to all reviewing IRB's and the FDA until the filing of a marketing application. The dates of these reports are based on the period of time since initial approval of the treatment IDE. After filing of a marketing application, progress reports must be submitted annually in accordance with the IDE regulations.

On the IDE Reports page, see Suggested Format For IDE Progress Report for guidance on the content of a progress report. The progress report must also include the number of patients treated with the device under the treatment IDE, the names of the investigators participating in the treatment IDE, and a brief description of the sponsor's efforts to pursue marketing approval or clearance of the device.

The sponsor of a treatment IDE is responsible for submitting all other reports required under §812.150 (Reports), such as unanticipated adverse device effects and final reports. The reports are submitted as reports to the original IDE application. See the IDE Reports page for additional guidance.
