Extract

In a typical magnetic resonance imaging (“MRI”) study of the brain, subjects are screened for contraindications before being placed in the bore of a large machine, the MRI scanner, which contains a powerful magnet. The scanner produces cross-sectional images of brain tissue as the subjects undergo a series of brief electromagnetic pulses, perceptible only as noise and vibration. If the protocol involves functional MRI (“fMRI”), a popular research technique for obtaining indirect measurements of brain activity, equipment might be used to present stimuli (sounds or pictures) during the scan, but generally the study involves no invasive procedures, no physical discomfort, and no ionizing radiation. Upon completion of the scan, MRI data is transferred to an investigator's computer for further analysis, often in combination with behavioral test results and clinical information obtained from subjects or their medical records.

This procedure sounds benign, and usually is. But an MRI scanner is a powerful medical device, capable of causing serious injury or death if operated carelessly.

1 Contraindications are factors that render a medical procedure or treatment inadvisable. A primary contraindication of MRI, due to the risk of trauma, heat-related injury, and device failure, is the presence in the body of metal fragments or of objects, such as implanted medical devices with metal components (e.g., aneurysm clips or pacemakers), unless such devices have been previously determined to be MRI-compatible.

6 A mythological knot tied by Gordius, king of Phyrgia, was so complex that prophecy held it could only be untied by the future king of Asia. Alexander the Great fulfilled the prophesy by resolving the knot with an innovative solution. Webster's New Encyclopedic Dictionary 793 (2002) (entry for “Gordian knot”). “Gordian knot” is a metaphorical expression for a problem that is “intricate” or “insoluable” on its own terms. Id.

7 This non-exhaustive list focuses narrowly on those regulations that pertain directly to the use of the MRI scanner in FDA-regulated research or other research involving human subjects. Other federal requirements applicable to research generally (e.g., regulations governing the expenditure of federal grant funds, policies for billing clinical research procedures to Medicare and Medicaid, regulations pertaining to scientific misconduct), are potentially implicated as well, though discussion of them is beyond the scope of this article. In addition to federal regulations, state common law, statutes, and regulations may also govern certain aspects of human subjects research.

13 Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 321(h)(2) (2006) (defining “device” as an object intended for use in the diagnosis of disease or other conditions). This definition includes an “instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including any component, part, or accessory, which is … intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals …” 21 U.S.C. §321(h)(2) (2006).

14 These FDA regulations include requirements for pre-market approval or clearance, good manufacturing practices, device reporting, and establishment registration. See 21 C.F.R. Parts 803,807,814, and 820.

15 Classification, which is based upon device risk, determines the type of submission (for pre-market notification versus pre-market approval) that a manufacturer must make to FDA to market a device. Class I and II devices that are not specifically exempt generally require clearance via pre-market notification only; an MRI scanner is a Class II device subject to pre-market notification requirements that must also meet specific product performance standards. 21 C.F.R. § 892.1000 (2006). To make significant changes (or changes that could alter the risk or effectiveness profile) to an MRI scanner or to its product labeling or other descriptions of intended use or indication, a manufacturer of an MRI must generally seek pre-market approval. On the other hand, a modification to a scanner or other device, if made solely for the care of an individual patient upon orders of a physician, is generally considered to result in a “custom” device that is not subject to pre-market notification or approval. 21 C.F.R. § 812.3(b) (2006). FDA device regulations pertaining to device manufacturing, quality control, labeling, and post-market reporting are beyond the scope of this paper.

16 See 21 C.F.R. §807, Subpart E (2006). Such modifications might include new scanner software systems or magnets of a greater field strength than those currently marketed. Very minor modifications that do not affect device safety or effectiveness may not require pre-market clearance.

17 See 21 C.F.R. § 814 (2006). An example of a new indication might be a revision to the labeling to reflect a claim that an MRI system can detect a specific brain disorder (versus a claim that it is useful for general medical imaging purposes).

18 Investigational Device Exemptions, 21 C.F.R. § 812.2 (2006) (stating the scope and applicability of the FDA's Investigational Device Exemptions).

19 21 C.F.R. §§ 812.2(c)(1), 812.2(c)(4) (2006). These studies are sometimes referred to as “IDE-exempt” studies.

20 Even when a study is IDE-exempt because the device studied is used in accordance with its approved labeling, if the purpose of the study is to collect safety or efficacy data (sometimes called “performance” data), the FDA's human subjects regulations would still apply.

21 Investigational Device Exemptions, 21 C.F.R. § 812.3 (2006).

22 The study sponsor should provide the IRB with the rationale for the NSR claim. If the IRB concurs with the sponsor's risk assessment, the study may begin without submission of an IDE application to FDA. Investigational Device Exemptions, 21 C.F.R. § 812.2(b)(ii) (2006) (stating the applicability of the FDA's Investigational Device Exemptions).

23 Investigational Device Exemptions, 21 C.F.R. § 812.20 (2006). The FDA generally considers the use of MRI in a clinical investigation to involve significant risk when the main static magnetic field is greater than 8 tesla (or 4 tesla for infants aged < 4 mos.), or when other operating conditions such as specific absorption rate (SAR) or sound pressure levels exceed parameters specified in FDA guidance. See FDA CDRH, Guidance for Industry and FDA Staff, Criteria for Significant Risk Investigations of Magnetic Resonance Devices, www.fda.gov (last visited July 6, 2007).

24 Investigational Device Exemptions, 21 C.F.R. § 812.3(m) (2006) (defining “significant risk” as one with the potential for serious risk to the health, safety, or welfare of a subject).

26 Regulatory interpretation conveyed via personal email communication to the author from Elisa Harvey, D.V.M., Ph.D., Director, IDE and HDE Programs, Office of Device Evaluation, Center for Devices and Radiological Health, FDA, Aug. 16, 2006. Where a scanner is not studied for a purpose related to treatment or diagnosis, it might also be argued that the scanner is not a medical device within the meaning of the statutory definition.

32 These circumstances include the following: when use of an investigational product meets regulatory criteria for an “emergency use;” when the IRB finds that the research meets strict criteria for “planned emergency use;” when the President makes findings necessary to waive prior consent for the administration of an investigational drug to military personnel; and, pursuant to a 2006 “interim final rule,” when an investigational in vitro diagnostic device is used in specific circumstances, without prior consent, to identify the causative agent in a public health, nuclear, chemical or bioterrorism emergency. In 2006 FDA's Center for Devices and Radiological Health also issued guidance indicating that it would exercise “enforcement discretion” with respect to studies of in vitro diagnostic devices conducted without consent, where the “human subject” consists of de-identified stored tissue.

38 Such research might also be regulated if conducted in one of a small number of states (e.g., Maryland) that have enacted clinical research legislation, or in a state whose medical records confidentiality laws regulate the disclosure of medical record information for research. See, e.g., Md. Code Ann., Health-Gen. § 13-2001 et seq. (2005) (human subjects research, enacted 2002); Md. Code Ann., Health-Gen. §§ 4-301(g), 4-305(b)(2)(i) (2005) (disclosure of medical records for research). The Maryland human subjects research legislation is relatively recent and it is unclear to what extent the state will attempt to enforce it, particularly with respect to secondary data studies.

85 Reports of financial interests made to regulators (DHHS or FDA) are treated as confidential under both regulations. Further, while DHHS regulations require grantee institutions to review investigators’ financial interests prospectively, FDA regulations require disclosure to the agency only retrospectively, upon submission of a marketing application. Thus, the FDA's financial disclosure regulations have no potential to protect the subjects of the studies conducted to support the application and serve only to give the agency a basis to question the validity of study data submitted by the sponsor.

93 Although federal regulations require institutions to review only the financial interests of researchers engaged in federally-funded research, and these regulations exclude researchers engaged in studies funded through the Small Business Innovation and Research (SBIR) and Small Business Technology Transfer (SBTTR) programs, 42 C.F.R. § 50.602 (2006), many research institutions now require all employed researchers to make annual financial disclosures.

94 California, which regulates research directly through its Protection of Human Subjects in Medical Experimentation Act, does require that participants in “medical experiments” be informed of the material financial interests of both the investigator and the research institution. “Medical experimentation” includes much drug and device research that is investigational or is not intended to benefit the subject. See Cal. Health & Safety Code § 24170 (2006).

95 If, however, the research were conducted in Maryland or California, the investigator would be required to comply with state laws pertaining to human subjects research. In Maryland, for instance, she would be required to obtain IRB review and informed consent for any research involving “human subjects” as defined in DHHS regulations. Cal. Health & Safety Code § 24170 (2006); Md. Code Ann., Health-Gen. §§ 13-2001-13-2004 (2006).

97 See 45 C.F.R. § 104(a)(3) (2006) (definition of a HIPAA covered entity, which includes a health care provider who transmits health information electronically in connection with one of the HIPAA standard transactions, such as billing).

98 Under HIPAA, academic institutions that own clinical entities such as hospitals, or whose medical or nursing school faculty derive revenue from clinical services are permitted to designate themselves as “hybrid” entities, restricting HIPAA coverage to those entities that engage in a HIPAA standard transactions.

100 MRI facilities that perform scans for clinical purposes may have their safety procedures evaluated during various accreditation processes, and are more likely to employ MR technicians who are certified radiology technicians or have obtained specific MR certification. Research MR scanning performed in research facilities or after-hours in clinical facilities is less likely to involve personnel who have formal training or certification as MR technicians.

Michael Carome, Associate Director for Regulatory Affairs, DHHS Office of Human Research Protections), concerning new OHRP guidance on adverse event reporting, Jordan Cohen, M.D., President of the Association of American Medical Colleges, noted that in the six years since DHHS Secretary Shalala issued her call for harmonization of the human subjects protection regulations of the DHHS and the FDA, “disappointingly little has been accomplished to date.” Letter from Jordan Cohen, M.D. to Michael Carome (Jan. 11, 2006), available at http://www.aamc.org/advocacy/library/research/corres/2006/011106.pdf.
