Clinical Chemistry and Clinical Toxicology Devices Panel of the Medical Devices Advisory Committee

Clinical Chemistry and Clinical Toxicology Devices Panel of the Medical Devices Advisory Committee Committee Meeting April 25, 2013 8:00 a.m. - 6:00 p.m. (Day 1 of 2) Agenda: On April 25, 2013, during session I, the committee will discuss and make recommendations on the appropriate regulatory classification for diagnostic devices known as methotrexate enzyme immunoassays. Methotrexate enzyme immunoassays are considered pre-Amendment devices since they were in commercial distribution prior to May 28, 1976 when the Medical Device Amendments became effective. Methotrexate enzyme immunoassays are currently regulated under the heading of “Enzyme Immunoassay, Methotrexate,” Product Code LAO, as unclassified under the 510(k) premarket notification authority. Methotrexate enzyme immunoassays are for the quantitative determination of methotrexate. The measurements obtained are used in monitoring levels of methotrexate to ensure appropriate drug therapy. FDA is seeking panel input on the safety and effectiveness of methotrexate enzyme immunoassays. On April 25, 2013, during session II, the committee will discuss and make recommendations on the appropriate regulatory classification for diagnostic devices known as phencyclidine (PCP) enzyme immunoassays and PCP radioimmunoassays. PCP enzyme immunoassays and PCP radioimmunoassays are considered pre-Amendment devices since they were in commercial distribution prior to May 28, 1976 when the Medical Device Amendments became effective. PCP enzyme immunoassays are currently regulated under the heading of “Enzyme Immunoassay, Phencyclidine,” Product Code LCM, and “Radioimmunoassay, Phencyclidine,” Product Code LCL, as unclassified under the 510(k) premarket notification authority. FDA is seeking panel input on the safety and effectiveness of PCP enzyme immunoassays and PCP radioimmunoassays.
