Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) is announcing the availability of the draft guidance entitled “Flow Cytometric Devices.” This draft guidance addresses the current major review concerns regarding submissions for flow cytometric devices used as in vitro diagnostic devices for leukocyte immunophenotyping and provides suggestions on the content of submissions for these types of devices. This draft guidance is not final nor is it in effect at this time.
Although you can comment on any guidance at any time (see 21 CFR 10.115(g)(5)), to ensure that the Agency considers your comment of this draft guidance before it begins work on the final version of the guidance, submit either electronic or written comments on the draft guidance by January 12, 2015.
An electronic copy of the guidance document is available for download from the Internet. See the SUPPLEMENTARY INFORMATION section for information on electronic access to the guidance. Submit written requests for a single hard copy of the draft guidance document entitled “Flow Cytometric Devices” to the Office of the Center Director, Guidance and Policy Development, Center for Devices and Radiological Health, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 66, Rm. 5431, Silver Spring, MD 20993-0002, or Office of Communication, Outreach and Development, Center for Biologics Evaluation and Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 71, Rm. 3128, Silver Spring, MD 20993-0002. Send one self-addressed adhesive label to assist that office in processing your request.
Submit electronic comments on the draft guidance to http://www.regulations.gov. Submit written comments to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

This draft guidance addresses certain issues that arise in premarket submissions for flow cytometric devices used as in vitro diagnostic devices for leukocyte immunophenotyping and provides suggestions on the content of submissions for these types of devices. It is intended to be used in conjunction with the other cited guidance documents referenced therein. In preparing your submission to FDA, we recommend that you contact FDA's Office of In Vitro Diagnostics and Radiological Health (see FOR FURTHER INFORMATION CONTACT) for additional information regarding your submission. This draft guidance focuses on issues relevant to flow cytometric devices with an expanded scope of review topics that reflect the recognition of a flow cytometric device as an analytical system, which includes processing reagents, processing instrumentation, flow cytometers, and analytical software, in addition to the monoclonal antibody (mAb) component. The information presented in this draft guidance is based on the following: (1) Current basic science, (2) clinical experience, and (3) previous submissions by manufacturers to FDA. As advances are made in science and medicine, the content of this guidance will be re-evaluated and revised as necessary to accommodate new knowledge.
This draft guidance is directed toward immunophenotyping of leukocytes using mAbs. However, the concepts may be applicable to related devices that utilize fluorochromes or fluorogenic substrates to measure ligand binding on solid particles in suspension, with or without mAbs. This draft guidance does not cover microscopy devices utilizing Start Printed Page 61645fluorescent or chromogenic enzyme-substrate detection methods (e.g., immunohistochemical stains) nor does it cover the use of flow cytometry for cell enrichment and cell sorting/purification when used in cell therapy product manufacturing.
II. Significance of Guidance
This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the Agency's current thinking on flow cytometric devices. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statute and regulations.
III. Electronic Access
Persons interested in obtaining a copy of the draft guidance may do so by downloading an electronic copy from the Internet. A search capability for all CDRH guidance documents is available at http://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/default.htm.
