[Federal Register Volume 83, Number 2 (Wednesday, January 3, 2018)] [Rules and Regulations] [Pages 232-234] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-28342] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration 21 CFR Part 864 [Docket No. FDA-2017-N-6599] Medical Devices; Hematology and Pathology Devices; Classification of a Cervical Intraepithelial Neoplasia Test System AGENCY: Food and Drug Administration, HHS. ACTION: Final order. ----------------------------------------------------------------------- SUMMARY: The Food and Drug Administration (FDA or we) is classifying the cervical intraepithelial neoplasia (CIN) test system into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the CIN test system's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens. DATES: This order is effective January 3, 2018. The classification was applicable on March 4, 2017. FOR FURTHER INFORMATION CONTACT: Steven Tjoe, Center for Devices and Radiological Health, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 66, Rm. 4550, Silver Spring, MD 20993-0002, 301-796-5866, [email protected]. SUPPLEMENTARY INFORMATION: I. Background Upon request, FDA has classified the cervical intraepithelial neoplasia (CIN) test system as class II (special controls), which we have determined will provide a reasonable assurance of safety and effectiveness. In addition, we believe this action will enhance patients' access to beneficial innovation, in part by reducing regulatory burdens by placing the device into a lower device class than the automatic class III assignment. The automatic assignment of class III occurs by operation of law and without any action by FDA, regardless of the level of risk posed by the new device. Any device that was not in commercial distribution before May 28, 1976, is automatically classified as, and remains within, class III and requires premarket approval unless and until FDA takes an action to classify or reclassify the device (see 21 U.S.C. 360c(f)(1)). We refer to these devices as ``postamendments devices'' because they were not in commercial distribution prior to the date of enactment of the Medical Device Amendments of 1976, which amended the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA may take a variety of actions in appropriate circumstances to classify or reclassify a device into class I or II. We may issue an order finding a new device to be substantially equivalent under section 513(i) of the FD&C Act (21 U.S.C. 360c(i)) to a predicate device that does not require premarket approval. We determine whether a new device is substantially equivalent to a predicate by means of the procedures for premarket notification under section 510(k) of the FD&C Act and part 807 (21 U.S.C. 360(k) and 21 CFR part 807, respectively). FDA may also classify a device through ``De Novo'' classification, a common name for the process authorized under section 513(f)(2) of the [[Page 233]] FD&C Act. Section 207 of the Food and Drug Administration Modernization Act of 1997 established the first procedure for De Novo classification (Pub. L. 105-115). Section 607 of the Food and Drug Administration Safety and Innovation Act modified the De Novo application process by adding a second procedure (Pub. L. 112-144). A device sponsor may utilize either procedure for De Novo classification. Under the first procedure, the person submits a 510(k) for a device that has not previously been classified. After receiving an order from FDA classifying the device into class III under section 513(f)(1) of the FD&C Act, the person then requests a classification under section 513(f)(2). Under the second procedure, rather than first submitting a 510(k) and then a request for classification, if the person determines that there is no legally marketed device upon which to base a determination of substantial equivalence, that person requests a classification under section 513(f)(2) of the FD&C Act. Under either procedure for De Novo classification, FDA shall classify the device by written order within 120 days. The classification will be according to the criteria under section 513(a)(1) of the FD&C Act. Although the device was automatically placed within class III, the De Novo classification is considered to be the initial classification of the device. We believe this De Novo classification will enhance patients' access to beneficial innovation, in part by reducing regulatory burdens. When FDA classifies a device into class I or II via the De Novo process, the device can serve as a predicate for future devices of that type, including for 510(k)s (see 21 U.S.C. 360c(f)(2)(B)(i)). As a result, other device sponsors do not have to submit a De Novo request or premarket approval application in order to market a substantially equivalent device (see 21 U.S.C. 360c(i), defining ``substantial equivalence''). Instead, sponsors can use the less-burdensome 510(k) process, when necessary, to market their device. II. De Novo Classification On May 23, 2016, Ventana Medical Systems, Inc., submitted a request for De Novo classification of the CINtec Histology. FDA reviewed the request in order to classify the device under the criteria for classification set forth in section 513(a)(1) of the FD&C Act. We classify devices into class II if general controls by themselves are insufficient to provide reasonable assurance of safety and effectiveness, but there is sufficient information to establish special controls that, in combination with the general controls, provide reasonable assurance of the safety and effectiveness of the device for its intended use (see 21 U.S.C. 360c(a)(1)(B)). After review of the information submitted in the request, we determined that the device can be classified into class II with the establishment of special controls. FDA has determined that these special controls, in addition to the general controls, will provide reasonable assurance of the safety and effectiveness of the device. Therefore, on March 4, 2017, FDA issued an order to the requestor classifying the device into class II. FDA is codifying the classification of the device by adding 21 CFR 864.1865. We have named the generic type of device the cervical intraepithelial neoplasia (CIN) test system, and it is identified as a device used to detect a biomarker associated with CIN in human tissues. The device is indicated as an adjunct test and not to be used as a stand-alone device. The test results must be interpreted in the context of the patient's clinical history including, but not limited to, prior and current cervical biopsy results, Papanicolaou (Pap) test results, human papillomavirus (HPV) test results, and morphology on hematoxylin and eosin (H&E) stained sections. This device is not intended to detect the presence of HPV. FDA has identified the following risks to health associated specifically with this type of device and the measures required to mitigate these risks in table 1. Table 1--Cervical Intraepithelial Neoplasia (CIN) Test System Risks to Health and Required Mitigations ------------------------------------------------------------------------ Required mitigations/21 CFR Identified risks section ------------------------------------------------------------------------ Inaccurate test results, such as false General controls and special positive or false negative results. controls (1) and (2) (21 CFR 864.1865(b)(1); 21 CFR 864.1865(b)(2)). Failure to correctly interpret test General controls and special results can lead to false positive or controls (1) and (2) (21 CFR false negative results. 864.1865(b)(1); 21 CFR 864.1865(b)(2)). ------------------------------------------------------------------------ FDA has determined that special controls, in combination with the general controls, address these risks to health and provide reasonable assurance of safety and effectiveness. For a device to fall within this classification, and thus avoid automatic classification in class III, it would have to comply with the special controls named in this final order. The necessary special controls appear in the regulation codified by this order. This device is subject to premarket notification requirements under section 510(k) of the FD&C Act. III. Analysis of Environmental Impact The Agency has determined under 21 CFR 25.34(b) that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required. IV. Paperwork Reduction Act of 1995 This final order establishes special controls that refer to previously approved collections of information found in other FDA regulations. These collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in 21 CFR parts 801 and 809, regarding labeling, have been approved under OMB control number 0910-0485; the collections of information in part 807, subpart E, regarding premarket notification submissions, have been approved under OMB control number 0910-0120; the collections of information in 21 CFR part 814, subparts A through E, regarding premarket approval, have been approved under OMB control number 0910- 0231; and the collections of information in the guidance document ``De Novo Classification Process (Evaluation of Automatic Class III Designation)'' have been approved under OMB control number 0910-0844. List of Subjects in 21 CFR Part 864 Blood, Medical devices, Packaging and containers. Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner [[Page 234]] of Food and Drugs, 21 CFR part 864 is amended as follows: PART 864--HEMATOLOGY AND PATHOLOGY DEVICES 0 1. The authority citation for part 864 continues to read as follows: Authority: 21 U.S.C. 351, 360, 360c, 360e, 360j, 360l, 371. 0 2. Add Sec. 864.1865 to subpart B to read as follows: Sec. 864.1865 Cervical intraepithelial neoplasia (CIN) test system. (a) Identification.
