Basic Principles of FDA Medical Device Regulation and How FDA Might Have Handled the Recent PIP CrisisBritish Institute of International and Comparative LawJune 10, 2013 Pamela Furman Forrest, Esq.Partner, King & Spalding LLPpforrest@kslaw.com202.661.7888
Agenda • Overview of FDA Medical Device Regulation • FDA Premarket Regulatory Scheme • How the Recent PIP Crisis Might Have Been Handled in the U.S.
Definition of “Device” • In general, a medical “device” is an instrument, apparatus, implement, machine, contrivance, implant, invitro reagent, or other similar or related article, including any component, part, or accessory: • 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, or • Intended to affect the structure or function of the body of man or other animals. See 21 U.S.C. § 321(h). • Product claims largely determine “device” status • The definition of “device” is interpreted broadly by FDA
General Principles • FDA imposes premarket and postmarket requirements on medical devices • The extent of regulation depends upon the device’s perceived risk • In order to be lawfully marketed, a device must comply with applicable premarket and postmarket requirements
Risk-Based Classification Scheme • Class I -- “Low risk” • Examples: orthopedic blade, tongue depressor • Typically exempt from premarket review requirements • Subject to postmarket “general controls.” See 21 U.S.C. § 360c(a)(1)(A) • Class II – “Moderate Risk” • Examples: powered wheelchair, endoscope • Typically subject to premarket notification (510(k)), postmarket “general controls,” and potentially “special controls.” See 21 U.S.C. § 360c(a)(1)(B) • Class III – “High Risk” • Examples: breast implants, coronary stents • Typically subject to premarket approval (PMA) and postmarket “general controls.” (See 21 U.S.C. § 360c(a)(1)(C)) • Potentially subject to additional conditions of approval
Two Main Premarket Pathways • Premarket notification (510(k)) • Premarket approval (PMA)
Registration and Listing • Establishments “engaged in the manufacture, preparation, propagation, compounding, assembly, or processing of a device” intended for commercial distribution in the U.S. are required to register with FDA • Registration puts firms on FDA’s “radar screen” for inspection • In general, these same establishments must file with FDA a list of the devices they have placed in commercial distribution • Listing provides FDA with information about the types of devices being manufactured
Quality System Regulation • The Quality System Regulation (QSR) forms the basis for assuring that only products that meet company specifications are released for distribution • The FDA uses compliance with the QSR to determine if a company is in control of its manufacturing process • QSR requirements govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging, labeling, storage, installation, and servicing of all finished devices
Medical Device Reporting • Medical Device Reports (“MDRs”) are intended to alert FDA to devices that may have caused or contributed to death or serious injury or that may eventually cause or contribute to a death or serious injury due to a malfunction • MDR requirements apply to manufacturers, importers, and device user facilities
Reports of Corrections and Removals • FDA has the authority to require manufacturers to recall devices, but rarely uses it. See 21 C.F.R. Part 810. Rather, most recalls (corrections and removals) are conducted voluntarily • Voluntary corrections to and removals of devices must be reported to FDA when the action is taken to reduce a risk to health or to remedy a violation of the Federal Food, Drug, and Cosmetic Act caused by the device that may present a risk to health. (See 21 C.F.R. Part 806)
Labeling • “Labeling”: All written, printed, or graphic matter (21 U.S.C. § 321(m)) • Upon an article or container OR • Accompanying such article • By statute, labeling cannot be “false or misleading” • All labeling claims must be: • Consistent with the product’s FDA-cleared or approved intended use (i.e., “on-label”) • Provide fair balance (i.e., provide information about risk with equal emphasis as information about benefits) • Have valid scientific support
Consequences of Noncompliance • Failure to comply with applicable FDA requirements typically renders a device adulterated or misbranded. (21 U.S.C. §§ 351 & 352) • Marketing an adulterated or misbranded device is a “prohibited act,” and can trigger FDA enforcement action. (21 U.S.C. § 331(a))
How FDA Learns of Noncompliances • Inspections • Trade Complaints • “Surfing” the web
Consequences of Noncompliance • FDA’s main statutory enforcement tools: • Seizure (21 U.S.C. § 334) • Injunction (21 U.S.C. § 332) • Criminal prosecution (21 U.S.C. § 333; 18 U.S.C. § 3571) • Civil Penalties (21 U.S.C. § 333(g)) • Issuance of a Warning Letter typically is the first step
Overview • A 510(k) is a premarket submission made to FDA to demonstrate that the device to be marketed is “substantially equivalent” to another legally marketed device • Substantial Equivalence means the device to be marketed has: • The same intended use as all of its predicates and • Similar technological characteristics as its predicate(s) or • Its technological differences • Do not raise any new questions of safety or effectiveness; and • Performance data demonstrate that the device is as safe and effective as its predicate device(s)
When 510(k) Clearance is Required • Introduction of a device subject to the 510(k) requirement (i.e., a Class I or Class II reserved device) • A change/modification to an already marketed device that could significantly affect its safety or effectiveness • A major change or modification to the device’s intended use
Traditional 510(k) Submissions • User fee • Standard fee is $4,960 for FY 2013 • Small business (< $100 million) for FY 2013 is $2,480 • Key elements of a traditional 510(k) • Device description • Substantial equivalence discussion • Comparison table • Narrative comparison
Key Elements of a Traditional 510(k) (cont.’d) • Proposed labeling • Sterilization and shelf life information • Biocompatibility information • Electrical safety information • Bench testing summaries • Animal testing summaries • Clinical testing summaries
Alternatives to Traditional 510(k)s • Special 510(k) • No changes to the device’s intended use/indications or fundamental scientific technology • Change being made to the company’s own device • Does not include data • Abbreviated 510(k) • Where FDA has issued an applicable device-specific guidance document; recognized an applicable consensus standard; or identified another special control • Must include a declaration of conformance to an FDA-recognized consensus standard; and/or a summary report regarding how the guidance document or other special control was used to address the risk • Does not include data
FDA’s Decisions on a 510(k) Notice • FDA actions on a 510(k) notice • Finds the device to be substantially equivalent (“SE”), i.e., clears the device, if it is at least as safe and effective as the predicate(s); • Requests additional information • Withdraws the 510(k) if the submitter does not respond to an FDA request within the allotted time; or • Finds the device to be not substantially equivalent (“NSE”)
510(k) Review Period • 90 days for traditional and abbreviated 510(k) notices • 30 days for a special 510(k) notice • FDA can extend that period by requesting additional information • When the sponsor of the 510(k) responds to FDA’s request for additional information, the 90-day (traditional / abbreviated) or 30-day (special) review period re-starts
Overview • Not a comparative submission • The device must be safe and effective for its intended use • A PMA generally requires more information (especially clinical data) and longer review time than a 510(k)
Original PMA Submission • User Fee • $248,000 for FY 2013 • $62,000 for small businesses (<$100 million in gross sales or revenue) • Fee waived for first PMA for a company with gross receipts or sales less than $30 million • Key elements of an original PMA submission • Device description • Detailed description of manufacturing processes
Original PMA Submission (cont’d) • Key elements of an original PMA submission (cont.’d) • Nonclinical studies summaries • Clinical studies summaries • Clinical investigator financial certification or disclosure • Proposed device labeling
PMA Review Process • Acceptance and filing review • Review to determine whether the PMA is administratively complete • Must be conducted within 45 days of receipt of the PMA • Substantive review • Review of performance, animal, clinical, and manufacturing information • Typically conducted by a scientific team of reviewers • 180 day review time • FDA may request additional information
PMA Review Process • Advisory Committee (Panel) review • FDA may refer a PMA for review by a panel of experts for various reasons • Occurs during the review period, typically after FDA has completed its substantive review • Panel review is conducted via a public meeting • Panel submits a final report to FDA that includes the Committee's recommendation and the basis for such recommendation on the PMA • Panel recommendation is not binding on the Agency, but FDA typically follows the panel recommendation
PMA Review Process • Pre-approval Bioresearch Monitoring (BiMo) inspection • Inspection of clinical trial sites and the study sponsor to assure accuracy of clinical data • Pre-approval manufacturing inspection • Inspection of manufacturing facilities to assure compliance with FDA requirements
FDA’s Decision • Approval Order • Decision that the device is safe and effective and the device may be legally marketed in the U.S. subject to the conditions in the approval order • Approvable Letter • FDA believes the device can be approved if specific minor additional information, e.g., labeling changes, are provided • Not approvable letter • Generally, additional information is needed to demonstrate the safety and effectiveness of the device • Order denying approval
Changes to a PMA Device • Regulations (21 C.F.R. § 814.39) require that manufacturers submit and receive approval for a PMA supplement before making a change affecting the safety or effectiveness of the device: • New intended use; • Labeling changes; • Different manufacturing facility; • Changes in sterilization procedures; • Changes in packaging; • Changes in performance or design specifications, circuits, components, ingredients, principle of operation, or physical design; and/or • Extension of expiration date based on a new protocol/procedure. • In general, all changes made to a PMA approved device must, in some way, be reported to FDA
Why the 510(k) Route is Generally Preferred • Approximately 10% of 510(k) notices include clinical data; almost all PMAs include clinical data • Generally, the 510(k) path is a quicker route to market than the PMA path even if the 510(k) contains clinical data • Shorter submissions • Shorter FDA review periods (90 days v. 180 days) • FDA Advisory Panel review generally not required
Bottom Line • The manufacturer reportedly began manufacturing breast implants with a non-medical grade silicone gel • This sort of deliberate, impermissible act is difficult for even the most stringent regulatory system to prevent
FDA Warning Letter and Import Detention • In June 2000, FDA issued a Warning Letter to PIP regarding its manufacturing process for saline breast implants, which cited multiple Quality System violations including: • Failure to maintain procedures for verifying and validating device design • Failure to maintain procedures for implementing corrective and preventive actions • Failure to maintain procedures for changes to a specification, method, process, or procedure • Failure to submit MDR reports • Failure to establish procedures for identifying training needs • FDA placed an import detention on PIP saline implants pending correction of the violations cited in the Warning Letter
FDA Advisory Panel Recommendation Against Approval of PIP PMA • PIP silicone breast implants were never sold in the U.S. • PIP saline breast implants were sold in the U.S. from 1996-2000 • In 2000, an FDA Advisory Panel voted unanimously to recommend that PIP’s PMA for saline breast implants not be approved • The Advisory Panel felt that PIP’s preclinical and clinical data were inadequate
Premarket Controls That Might Have Kept PIP Silicone Implants Off the Market • FDA concerns regarding PIP’s proposed clinical trials might have led to disapproval of PIP’s Investigational Device Exemption (IDE) application • Bioresearch Monitoring (BiMo) inspection might have raised concerns about PIP’s clinical study-related practices • PIP might have failed to satisfactorily respond to FDA’s deficiency letters during the PMA review process • FDA might have found violative practices during its pre-approval QSR inspection of PIP
Postmarket Enforcement Tools That Might Have Been Used Against PIP • FDA inspection – routine and/or for cause • Often leads to 483, Untitled Letter, Warning Letter, and/or import detention (for foreign manufacturers) • Seizure • Injunction • Civil Penalties • Initiation of criminal proceedings
Postmarket Tools (cont’d) • Cease Distribution and Notification (CD&N) Order • Requires a firm to immediately cease distribution of a device, notify health professionals and device user facilities of the Order, and instruct them to cease use of the device • There must be a “reasonable probability that a device . . . would cause serious, adverse health consequences or death” • Mandatory Recall • FDA can amend a CD&N order to require a recall • Repair, Replacement, or Refund Order • Among other things, device must “present an unreasonable risk of substantial harm to public health”
