Indications for Use

The FilmArray® Pneumonia Panel is a multiplexed nucleic acid test intended for use with FilmArray® 2.0 or FilmArray® Torch systems for the simultaneous detection and identification of multiple respiratory viral and bacterial nucleic acids, as well as select antimicrobial resistance genes, in sputum-like specimens (induced or expectorated sputum, or endotracheal aspirates) or bronchoalveolar lavage (BAL)-like specimens (BAL or mini-BAL) obtained from individuals suspected of lower respiratory tract infection. The following bacteria are reported semi-quantitatively with bins representing approximately 10^4, 10^5, 10^6, or ≥10^7 genomic copies of bacterial nucleic acid per milliliter (copies/mL) of specimen, to aid in estimating relative abundance of nucleic acid from these common bacteria within a specimen: Acinetobacter calcoaceticus-baumannii complex, Enterobacter cloacae complex, Escherichia coli, Haemophilus influenzae, Klebsiella aerogenes, Klebsiella oxytoca, Klebsiella pneumoniae group, Moraxella catarrhalis, Proteus spp., Pseudomonas aeruginosa, Serratia marcescens, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pneumoniae, Streptococcus pyogenes. The following atypical bacteria, viruses, and antimicrobial resistance genes are reported qualitatively: Atypical Bacteria: Chlamydia pneumoniae, Legionella pneumophila, Mycoplasma pneumoniae. Viruses: Adenovirus, Coronavirus, Human Metapneumovirus, Human Rhinovirus/Enterovirus, Influenza A, Influenza B, Parainfluenza Virus, Respiratory Syncytial Virus. Antimicrobial Resistance Genes: CTX-M, IMP, KPC, NDM, OXA-48-like, VIM, mecA/C and MREJ. The detection and identification of specific viral and bacterial nucleic acids, as well as the estimation of relative abundance of nucleic acid from common bacterial analytes, within specimens collected from individuals exhibiting signs and/or symptoms of a respiratory infection, aids in the diagnosis of lower respiratory infection with other clinical and epidemiological information. The results of this test should not be used as for diagnosis, treatment, or other patient management decisions.

Device Story

FilmArray Pneumonia Panel; multiplex nucleic acid test; detects/identifies microorganisms and resistance markers in respiratory specimens. Modification involves inclusion of additional limitations in device labeling. Fundamental scientific technology remains unchanged from previously cleared device. Used in clinical laboratory settings; provides rapid diagnostic results to assist clinicians in identifying pathogens and resistance markers to guide antimicrobial therapy.

Clinical Evidence

No new clinical data provided; modification pertains to labeling limitations. Substantial equivalence supported by design control activities and risk analysis demonstrating no change to fundamental scientific technology.

Technological Characteristics

Nested multiplex PCR; high-resolution melt curve analysis; automated sample prep via magnetic beads; reagent storage at room temperature; compatible with FilmArray 2.0/Torch systems; software-controlled pneumatic bladders/pistons; Peltier-based thermal cycling; fluorescent detection.

Indications for Use

Indicated for the detection and identification of microorganisms and associated resistance marker nucleic acids directly in respiratory specimens.

Regulatory Classification

Identification

A device to detect and identify microorganisms and associated resistance marker nucleic acids directly from respiratory specimens is an in vitro diagnostic device intended for the detection and identification of microorganisms and associated resistance markers in respiratory specimens collected from patients with signs or symptoms of respiratory infection. The device is intended to aid in the diagnosis of respiratory infection in conjunction with clinical signs and symptoms and other laboratory findings. These devices do not provide confirmation of antibiotic susceptibility since mechanisms of resistance may exist other than those detected by the device.

Special Controls

*Classification.* Class II (special controls). The special controls for this device are:(1) The intended use for the 21 CFR 809.10 labeling must include a detailed description of what the device detects, the type of results provided to the user, the clinical indications appropriate for test use, and the specific population(s) for which the device is intended. (2) The 21 CFR 809.10(b) labeling must include: (i) A detailed device description, including all device components, control elements incorporated into the test procedure, instrument requirements, ancillary reagents required but not provided, and a detailed explanation of the methodology, including all pre-analytical methods for processing of specimens. (ii) Performance characteristics from analytical studies, including, but not limited to, limit of detection, inclusivity, reproducibility, cross reactivity, interfering substances, competitive inhibition, carryover/cross contamination, specimen stability, and linearity, as applicable. (iii) A limiting statement that the device is intended to be used in conjunction with clinical history, signs and symptoms, and results of other diagnostic tests, including culture and antimicrobial susceptibility testing. (iv) A detailed explanation of the interpretation of test results for clinical specimens and acceptance criteria for any quality control testing. (v) A limiting statement that negative results for microorganisms do not preclude the possibility of infection, and should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. (vi) If applicable, a limiting statement that detected microorganisms may not be the cause of lower respiratory tract infection and may be indicative of colonizing or normal respiratory flora. (vii) If applicable, a limiting statement that detection of resistance markers cannot be definitively linked to specific microorganisms and that the source of a detected resistance marker may be an organism not detected by the assay, including colonizing flora. (viii) If applicable, a limiting statement that detection of antibiotic resistance markers may not correlate with phenotypic gene expression. (3) The 21 CFR 809.10(b) labeling and any test report generated by the device must include a limiting statement that negative results for resistance markers do not indicate susceptibility of detected microorganisms. (4) Design verification and validation must include: (i) Performance characteristics from clinical studies that include prospective (sequential) samples and, if appropriate, additional characterized samples. The study must be performed on a study population consistent with the intended use population and compare the device performance to results obtained from an FDA accepted reference method and/or FDA accepted comparator method, as appropriate. Results from the clinical studies must include the clinical study protocol (including predefined statistical analysis plan, if applicable), clinical study report, and results of all statistical analyses. (ii) A detailed device description including the following: (A) Thorough description of the assay methodology including, but not limited to, primer/probe sequences, primer/probe design, and rationale for target sequence selection, as applicable. (B) Algorithm used to generate a final result from raw data (e.g., how raw signals are converted into a reported result). (iii) A detailed description of device software, including, but not limited to, validation activities and outcomes. (iv) As part of the risk management activities, an appropriate end user device training program must be offered as an effort to mitigate the risk of failure from user error.
