11. University of Miami HSRO October 24, 2008 11 You have a combination product
12. University of Miami HSRO October 24, 2008 12 Primary Mode of Action (PMOA)
Primary mode of action is the statutory criterion FDA must use to determine the agency component with primary jurisdiction for the review and regulation of a combination product.
21 U.S.C. § 503(g)
13. University of Miami HSRO October 24, 2008 13 PMOA, continued
PMOA not defined in statute, now defined in regulations: 21 CFR 3.2(k) and (m).
Final Rule issued on August 25, 2005 and can be accessed at: http://www.fda.gov/OHRMS/DOCKETS/98fr/05-16527.htm
14. University of Miami HSRO October 24, 2008 14 Mode of Action
Mode of Action: the means by which a product achieves an intended therapeutic effect or action. 21 CFR 3.2(k)
Three types of modes of action: biological product, device, drug
Combination products typically have more than one identifiable mode of action
15. University of Miami HSRO October 24, 2008 15 Primary Mode of Action
Primary mode of action is the single mode of action of a combination product that provides the most important therapeutic action of the combination product. The most important therapeutic action is the mode of action expected to make the greatest contribution to the overall intended therapeutic effects of the combination product.
21 CFR 3.2(m)
16. University of Miami HSRO October 24, 2008 16 PMOA algorithm If unable to determine most important therapeutic action with reasonable certainty, consider:
Consistency: is there an agency component that regulates other combination products presenting similar questions of S & E with regard to combination product as a whole?
Safety and Effectiveness: which agency component has the most expertise related to most significant S&E questions presented by combination product?
17. University of Miami HSRO October 24, 2008 17 PMOA - CDER or CDRH?
18. University of Miami HSRO October 24, 2008 18 Request for Designation (RFD)
Voluntary Formal Process
21 CFR Part 3
Classification (what am I?)
Assignment (where do I go?)
Clarification of Regulatory Pathway (what do I do when I get there?)

21. University of Miami HSRO October 24, 2008 21 Section 520(g) of the FD&C Act Purpose of an IDE
To encourage discovery and development of useful medical devices for human use, to the extent consistent with the protection of the public health and safety and with ethical standards, while maintaining optimum freedom for scientific investigators in their pursuit of that purpose
22. University of Miami HSRO October 24, 2008 22 Purpose of an IDE An approved Investigational Device Exemption (IDE) allows:
an investigational device to be used in a clinical study in order to collect S&E data required to support a Premarket Approval (PMA) application, a Humanitarian Device Exemption (HDE), or a Premarket Notification [510(k)] submission to FDA.
a device to be shipped lawfully for the purpose of conducting investigations
23. University of Miami HSRO October 24, 2008 23 Provisions of the IDE Regulation All clinical investigations subject to the regulation must be approved before they can begin
Assigns responsibilities to all participants in clinical investigation
All subjects in the investigation must give informed consent
24. University of Miami HSRO October 24, 2008 24 Definitions Investigational Device
Is still in the developmental stage
Object of a clinical investigation is to determine safety and efficacy
Is not considered to be in commercial distribution
Investigational Use
Clinical evaluation of an already legally marketed device for a new intended use
25. University of Miami HSRO October 24, 2008 25 Studies Subject to the Regulation To support marketing application [PMA, HDE or 510(k)]
Collection of safety and effectiveness information (e.g., for a new intended use of a legally marketed device)
Sponsor-investigator studies of unapproved devices or new intended use of approved device (even if no marketing application planned)
26. University of Miami HSRO October 24, 2008 26 Studies Exempt from need for IDE Preamendments (pre-1976) devices
510(k)-cleared or PMA-approved devices, if used in accordance with approved labeling
In vitro diagnostic devices (most of the time)

27. University of Miami HSRO October 24, 2008 27 “Practice of Medicine” “Nothing in this Act shall be construed to limit or interfere with the authority of a health care practitioner to prescribe or administer any legally marketed device to a patient for any condition or disease within a legitimate health care practitioner-patient relationship….”
28. University of Miami HSRO October 24, 2008 28 “Practice of Medicine” Physician should:
Be well informed about the product
Use firm scientific rationale and sound medical evidence
Maintain records on use and effects
IDE not req’d; Institution may require IRB review/approval and IC
Other prohibitions still apply
29. University of Miami HSRO October 24, 2008 29 “Basic Physiological Research” Investigating a physiological principle
No intent to develop the device for marketing
Only using the device to address the research question
? No IDE needed; IRB approval and
IC should be obtained
30. University of Miami HSRO October 24, 2008 30 If NOT Exempt from Device Regulation, Then… Need to assess whether proposed study of device is considered SIGNIFICANT RISK (SR), or NONSIGNIFICANT RISK (NSR)
IRBs can and do make this assessment most of the time
FDA can assist IRBs and/or investigators by making risk determinations; this determination is final
See IRB Information Sheet on SR/NSR: http://www.fda.gov/oc/ohrt/irbs/devices.html#risk
31. University of Miami HSRO October 24, 2008 31 Significant Risk (SR) Study Presents a potential serious risk to the health, safety, and welfare of a subject and is:
an implant; or
used in supporting or sustaining human life; or
of substantial importance in diagnosing, curing, mitigating, or treating disease or preventing impairment of human health
32. University of Miami HSRO October 24, 2008 32 Significant Risk (SR) Study Examples
33. University of Miami HSRO October 24, 2008 33 Significant Risk IDEs Sponsor submits IDE application to FDA
FDA approves, conditionally approves or disapproves IDE within 30 calender days
Sponsor obtains IRB approval
After both FDA and IRB approve the investigation, study can begin
34. University of Miami HSRO October 24, 2008 34 Non-significant Risk IDEs Sponsor presents protocol to IRB and a statement why investigation does not pose significant risk
If IRB approves the investigation as NSR, it can begin
Abbreviated IDE requirements (labeling, IRB, consent, monitoring, reporting, prohibition on promotion)
No IDE submission to FDA needed

Manufacturing Information
Investigator and IRB Information
Sales Information
Labeling
Informed Consent
45. Investigator responsibilities Conduct the research in compliance with the signed agreement with the sponsor, the investigational plan, applicable regulations, and any conditions imposed by reviewing IRB or FDA
Supervise all testing of the device on human subjects
Ensure requirements for obtaining IC are met
Use investigational device only with subjects under investigator’s supervision and supply investigational device only to persons authorized to receive them
46. Investigator responsibilities (continued) Return any remaining devices to sponsor or dispose of them as sponsor directs after the completion/termination of the investigation or the investigator’s part in the investigation
Maintain accurate/complete/current records related to participation in investigation, including all correspondence, receipt/use/disposition of device, each subject’s case history and exposure to the device, protocol with records related to any deviations, and any other records required by regulations or specific requirement
47. Investigator responsibilities (continued) Permit FDA to inspect/copy any records related to research
Prepare/ submit to sponsor and, when required by regulation, reviewing IRB and monitor, complete/accurate/timely reports, including reports on unanticipated device effects, progress, deviation from investigational plan, any use of device without informed consent, a final report, and any additional information requested by FDA or IRB about any aspect of the investigation
48. Supervision of a Clinical Investigation In a clinical investigation, the investigator commits to conduct and/or supervise the process personally.
The investigator who delegates tasks related to the research is responsible for providing adequate supervision to whomever the task is delegated and is accountable for regulatory violations caused from failure to supervise the conduct of the study.
49. FDA Assessment of Adequacy of Supervision of a Clinical Investigation FDA will focus on four major issues:
Were delegated individuals qualified to perform the tasks?
Did study staff receive adequate training on doing delegated tasks and did they have an adequate understanding of the study?
Was there adequate supervision/involvement in ongoing conduct of the study?
Was there adequate supervision/oversight of any third parties involved in conduct of a study (to the extent such supervision/oversight reasonably possible)?
50. Protecting the Rights ,Safety, and Welfare of Study Subjects 1. Reasonable Medical Care Necessitated by Research Participation
Investigator should ensure adequate care provided for any adverse events
Investigator should inform subject’s primary physician about participation in research if subject has primary physician and agrees to such notification
Investigator should make every effort to obtain appropriate care, if investigator does not possess necessary skills
2. Reasonable Access to Medical Care
Investigator should be readily available to subjects during conduct of trial
Availability important where subjects receiving intervention with significant toxicity or abuse potential
If investigator unavailable, responsibility for subjects should be delegated to a specific qualified person readily available to subjects
51. Protecting the Rights ,Safety, and Welfare of Study Subjects (Cont’d) 3. Protocol violations that Present Unreasonable Risks
Situation where failure to follow protocol may be considered a failure to protect rights, safety, and welfare of subjects
Failure to follow inclusion’/exclusion criteria specifically intended to exclude subjects for whom study intervention poses unreasonable risks
Failure to perform safety assessments intended to detect toxicity/adverse events within protocol-specified time frames
Investigators should seek to minimize risks by adhering close to study protocol
52. University of Miami HSRO October 24, 2008 52 Enforcement of Good Clinical Practices (GCPs)
Inspection Program
Sponsors, IRBs, and investigators are required to permit authorized FDA employees reasonable access at reasonable times to inspect and copy all records relating to an investigation.
To assure compliance with the IDE and related regulations, FDA inspects sponsors, clinical investigators, and institutional review boards.
The inspection program is referred to as bioresearch monitoring (BIMO) and is overseen the CDRH’s Office of Compliance, Division of Bioresearch Monitoring.
