Download as PDF 38636 Federal Register / Vol. 74, No. 148 / Tuesday, August 4, 2009 / Notices Participants randomly assigned into the intervention arms will receive comprehensive or brief interventional services from two trained interventionists. The interventions will be delivered in face-to-face encounters as well as over the telephone and the first dose of the intervention will be delivered on the day the participant is enrolled into study. During the first face-to-face encounter, an interventionist will administer a retention risk screener. This screener is a clinical tool that will help identify attitudes, barriers, and unmet needs that might prevent a patient from staying in care. The screener contains three sections: (1) Attitudes and beliefs about HIV care and treatment, (2) barriers to consistent clinic attendance (e.g., transportation, child care, housing instability, scheduling problems, and lack of social support), and (3) recent drug/alcohol use and mental health. The information obtained from the risk screener will be used to tailor the interventions to each individual patient’s needs. Because a patient’s situation or needs may change over time, the screener will be re- administered to intervention arm participants at a minimum every 3–4 months during a clinic visit or other arranged face-to-face meetings outside of the clinic. In addition, the study coordinator will obtain contact/locator information for all participants enrolled in the intervention arm. Contact information will be updated as necessary by the intervention staff.

ACTION: Notice. SUMMARY: The Food and Drug Administration (FDA) is announcing the issuance of two Emergency Use Authorizations (EUAs) (the Authorizations), one of which was amended, for certain in vitro diagnostic devices. FDA is issuing the Authorizations under the Federal Food, Drug, and Cosmetic Act (the act), as PO 00000 Frm 00060 Fmt 4703 Sfmt 4703 requested by the Centers for Disease Control and Prevention (CDC). The Authorizations contain, among other things, conditions on the emergency use of the authorized in vitro diagnostics. The Authorizations follow the determination by the Acting Secretary of the Department of Health and Human Services, Charles E. Johnson (the Acting Secretary), that a public health emergency exists involving Swine Influenza A (now known as 2009 H1N1 Influenza A or 2009 H1N1 flu) that affects, or has the significant potential to affect, national security. On the basis of such determination, the Acting Secretary declared an emergency justifying the authorization of the emergency use of certain in vitro diagnostics, accompanied by emergency use information subject to the terms of any authorization issued under the act. E:\FR\FM\04AUN1.SGM 04AUN1 Federal Register / Vol. 74, No. 148 / Tuesday, August 4, 2009 / Notices The Authorizations, which include an explanation of the reasons for issuance, are reprinted in this document. Elsewhere in this issue of the Federal Register, FDA is announcing the issuance of EUAs for certain antiviral drug products and the issuance of an EUA for certain personal respiratory protection devices. DATES: The authorization for the Swine Influenza Virus Real-time RT–PCR Detection Panel (rRT-PCR Swine Flu Panel) is effective as of April 27, 2009. The Authorization for the previouslycleared CDC Human Influenza Virus Real-time RT–PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA2) and Viral Culture is effective as of May 2, 2009. ADDRESSES: Submit written requests for single copies of the EUAs to the Office of Counterterrorism and Emerging Threats (HF–29), Food and Drug Administration, 5600 Fishers Lane, rm. 14C–26, Rockville, MD 20857.

FOR FURTHER INFORMATION CONTACT: Boris Lushniak, Office of Counterterrorism and Emerging Threats (HF–29), Food and Drug Administration, 5600 Fishers Lane, Rockville, MD 20857, 301–827–4067. SUPPLEMENTARY INFORMATION: mstockstill on DSKH9S0YB1PROD with NOTICES I. Background Section 564 of the act (21 U.S.C. 360bbb–3), as amended by the Project BioShield Act of 2004 (Public Law 108– 276), allows FDA to strengthen the public health protections against biological, chemical, nuclear, and radiological agents. Among other things, section 564 of the act allows FDA to authorize the use of an unapproved medical product or an unapproved use of an approved medical product during a public health emergency that affects, or has a significant potential to affect, national security, and that involves biological, chemical, radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such agent or agents. With this EUA authority, FDA can help assure that medical countermeasures may be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions caused by such agents, when there are no adequate, approved, and available alternatives. VerDate Nov<24>2008 16:07 Aug 03, 2009 Jkt 217001 Section 564(b)(1) of the act provides that, before an EUA may be issued, the Secretary must declare an emergency justifying the authorization based on one of the following grounds: ‘‘(A) a determination by the Secretary of Homeland Security that there is a domestic emergency, or a significant potential for a domestic emergency, involving a heightened risk of attack with a specified biological, chemical, radiological, or nuclear agent or agents; (B) a determination by the Secretary of Defense that there is a military emergency, or a significant potential for a military emergency, involving a heightened risk to United States military forces of attack with a specified biological, chemical, radiological, or nuclear agent or agents; or (C) a determination by the Secretary of a public health emergency under section 319 of the Public Health Service Act that affects, or has a significant potential to affect, national security, and that involves a specified biological, chemical, radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such agent or agents.’’ Once the Secretary has declared an emergency justifying an authorization under section 564 of the act, FDA may authorize the emergency use of a drug, device, or biological product if the agency concludes that the statutory criteria are satisfied. Under section 564(h)(1) of the act, FDA is required to publish, in the Federal Register, a notice of each authorization, and each termination or revocation of an authorization, and an explanation of the reasons for the action. Section 564 of the act permits FDA to authorize the introduction into interstate commerce of a drug, device, or biological product intended for use in a declared emergency. Products appropriate for emergency use may include products and uses that are not approved, cleared, or licensed under sections 505, 510(k), and 515 of the act (21 U.S.C. 355, 360(k), and 360e) or section 351 of the PHS Act (42 U.S.C. 262). FDA may issue an EUA only if, after consultation with the National Institutes of Health and CDC (to the extent feasible and appropriate given the circumstances of the emergency), FDA1 concludes: (1) That an agent specified in a declaration of emergency can cause a serious or lifethreatening disease or condition; (2) that, based on the totality of scientific evidence available to FDA, including data from adequate and well-controlled 1 The Secretary has delegated his authority to issue an EUA under section 564 of the act to the Commissioner of Food and Drugs. PO 00000 Frm 00061 Fmt 4703 Sfmt 4703 38637 clinical trials, if available, it is reasonable to believe that: (A) the product may be effective in diagnosing, treating, or preventing—(1) such disease or condition; or (2) a serious or lifethreatening disease or condition caused by a product authorized under Section 564, approved or cleared under this Act, or licensed under Section 351 of the Public Health Service Act (PHS Act), for diagnosing, treating, or preventing such a disease or condition caused by such an agent; and (B) the known and potential benefits of the product, when used to diagnose, prevent, or treat such disease or condition, outweigh the known and potential risks of the product; (3) that there is no adequate, approved, and available alternative to the product for diagnosing, preventing, or treating such disease or condition; and (4) that such other criteria as the Secretary may by regulation prescribe are satisfied. No other criteria of issuance have been prescribed by regulation under section 564(c)(4) of the act. Because the statute is self-executing, FDA does not require regulations or guidance to implement the EUA authority. However, in the Federal Register of July 26, 2007 (72 FR 41083), FDA announced the availability of a guidance entitled ‘‘Emergency Use Authorization of Medical Products.’’ The guidance provides more information for stakeholders and the public about the EUA authority and the agency’s process for the consideration of EUA requests. II. EUA Request for Certain In Vitro Diagnostic Products On April 26, 2009, under section 564(b)(1)(C) of the act, the Acting Secretary determined that a public health emergency exists involving Swine Influenza A (now known as 2009 H1N1 Influenza A or 2009 H1N1 flu) that affects, or has the significant potential to affect, national security. On April 26, 2009, under section 564(b) of the act, and on the basis of such determination, the Acting Secretary declared an emergency justifying the authorization of certain in vitro diagnostics for detection of Swine Influenza A (2009 H1N1 flu virus), accompanied by emergency use information subject to the terms of any authorization issued under 21 U.S.C. 360bbb–3(a). Notice of the determination and the declaration of the Acting Secretary is published elsewhere in this issue of the Federal Register. On April 27, 2009, in response to a CDC request, FDA issued an EUA for the Swine Influenza Virus Real-time RT– PCR Detection Panel (rRT-PCR Swine Flu Panel) with certain written E:\FR\FM\04AUN1.SGM 04AUN1 38638 Federal Register / Vol. 74, No. 148 / Tuesday, August 4, 2009 / Notices information, including fact sheets for healthcare providers and patients and adequate directions for use, which are authorized under the EUA. On May 2, 2009, in response to a CDC request to allow use of the rRT-PCR Swine Flu Panel for different sample types and different reagents, FDA amended the rRT-PCR Swine Flu Panel Authorization letter and reissued the Authorization letter in its entirety, with amended written information, including adequate directions for use. In addition, on May 2, 2009, in response to a CDC request, FDA issued an EUA with certain written information, including adequate directions for use, to allow the use of the FDA-cleared in vitro diagnostic device, CDC Human Influenza Virus Real-time RT–PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA2) and Viral Culture) (CDC rRT-PCR flu panel), for patient specimen types and reagents in addition to those of the cleared CDC rRT-PCR flu panel. III. Electronic Access An electronic version of this document and the full text of the Authorizations are available on the Internet at https://www.regulations.gov. IV. The Authorizations Having concluded that the criteria for issuance of the Authorizations, one as amended, under section 564(c) of the act are met, FDA has authorized the emergency use of certain in vitro diagnostic devices. The Authorization for the rRT-PCR Swine Flu Panel, as amended and reissued in its entirety on May 2, 2009, follows and provides an explanation of the reasons for its issuance, as required by section 564(h)(1) of the act: Richard E. Besser, MD Acting Director Centers for Disease Control and Prevention 1600 Clifton Road, MS C-12 Atlanta, GA 30333 Clifton, Bldg. 1, Room 6430 Dear Dr. Besser: On April 27, 2009, FDA issued a letter authorizing the emergency use of the Swine Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR Swine Flu Panel) for the presumptive diagnosis of swine influenza A (H1N1), pursuant to section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. § 360bbb-3) by public health and other qualified laboratories. On May 1, 2009, CDC submitted a request for an amendment to the Emergency Use Authorization. In response to that request, the letter authorizing emergency use of the rRT-PCR Swine Flu Panel is being reissued in its entirety with the amendments, as requested by CDC, incorporated.1 On April 26, 2009, pursuant to section 564(b)(1)(C) of the Act (21 U.S.C. § 360bbb-3(b)(1)(C)), the Secretary of the Department of Health and Human Services (HHS) determined that there is a public health emergency under 42 U.S.C. § 247d that affects, or has a significant potential to affect, national security, and that involves a specified biological, chemical, radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such an agent or agents -- in this case, swine influenza A (H1N1).2 Pursuant to section 564(b) of the Act (21 U.S.C. § 360bbb-3(b)), and on the basis of such determination, the Secretary of the Department of Health and Human Services then declared an emergency justifying the authorization of the emergency use of the Swine Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR Swine Flu Panel) subject to the terms of any authorization issued under 21 U.S.C. § 360bbb-3(a). Having concluded that the criteria for issuance of this authorization under section 564(c) of the Act (21 U.S.C. § 360bbb-3(c)) are met, I am authorizing the emergency use of the Swine Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR Swine Flu Panel)3 for the presumptive diagnosis of swine influenza A (H1N1) virus infection in human individuals who have been diagnosed with influenza A caused by a virus not subtypeable by currently available FDA-cleared devices, subject to the terms of this authorization. I. Criteria for Issuance of Authorization I have concluded that the emergency use of the rRT-PCR Swine Flu Panel for the presumptive diagnosis of swine influenza A (H1N1) virus infection for human individuals who are diagnosed with influenza A caused by a virus that is not subtypeable by currently available FDA-cleared devices meets the criteria for issuance of an authorization under section 564(c) of the Act, because I have concluded that: (1) The recently isolated novel 2009 influenza A (H1N1), or swine flu, virus can cause influenza, a serious or life threatening disease or condition to humans infected by this virus; mstockstill on DSKH9S0YB1PROD with NOTICES (2) based on the totality of scientific evidence available to FDA, it is reasonable to believe that the rRT-PCR Swine Flu Panel may be effective in the presumptive diagnosis of swine influenza A (H1N1) virus infection, and that the known and potential benefits of the rRT-PCR Swine Flu Panel, when used in the presumptive diagnosis of swine influenza A (H1N1) virus infection, outweigh the known and potential risks of such products; and (3) there is no adequate, approved, and available alternative to the emergency use of the rRT-PCR Swine Flu Panel for the presumptive diagnosis of swine influenza A (H1N1) virus infection.4 Therefore, I have concluded that the emergency use of the rRT-PCR Swine Flu Panel for the presumptive diagnosis of swine influenza A (H1N1) virus infection in human individuals who are diagnosed with influenza A infections not subtypeable by currently available FDA-cleared devices meets the above criteria for issuance of an authorization.

The authorized rRT-PCR Swine Flu Panel is as follows: The Swine Influenza Virus Real-time RT-PCR Detection Panel is a panel of oligonucleotide primers and dual-labeled hydrolysis (Taqman®) probes for use in the real-time RT-PCR assay on the ABI 7500 Fast Dx Real-Time PCR instrument for the in vitro qualitative detection of 2009 H1N1 influenza viral RNA in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/TS swab, or nasal aspirate (NA) specimens from patients with signs and symptoms of respiratory infection and viral culture. The universal 2009 H1N1 influenza swInfA (NP gene) and swH1 (HA gene) primer and probe sets are designed for detection of 2009 A/H1N1 influenza viruses. In addition rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) authorized for emergency use utilizes the AgPath-IDTM One-Step RT-PCR Kit Human amplification reagents. The rRT-PCR Swine Flu Panel includes the following primer and probe sets: • InfA detects universal influenza A strains in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/ TS swab, or nasal aspirate (NA) specimens from patients with signs and symptoms of respiratory infection, and virus culture. • swInfA specifically detects swine influenza A strains (NP gene) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/TS swab, or nasal aspirate (NA) specimens from patients with signs and symptoms of respiratory infection, and virus culture. • swH1 is specific for swine influenza A, subtype H1 (HA gene) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/TS swab, or nasal aspirate (NA) specimens from patients with signs and symptoms of respiratory infection, and viral culture. The rRT-PCR Swine Flu Panel also includes control materials: • RNase P (RP) detects human RNase P and is used as a positive control with human clinical specimens to indicate that adequate isolation of nucleic acid resulted from the extraction of the clinical specimen. • Swine Influenza Panel Real-Time RT-PCR Positive Control (SIPC) is a positive control designed to react with all the primer and probe sets including RNase P. The above rRT-PCR Swine Flu Panel, when labeled consistent with the attached template is authorized to be distributed to public health and other qualified laboratories5 under this EUA, despite the fact that it does not meet certain requirements otherwise required by federal law. The following written information pertaining to the emergency use of the authorized rRT-PCR Swine Flu Panel is authorized to be made available to health care providers and patients: • Fact Sheet For Healthcare Providers: Interpreting Swine Influenza Rt-Pcr Detection Panel Test Results • Fact Sheet For Patients: Understanding Swine Influenza Kit Test Results See attached. As described in section IV below, CDC and the appropriate state and/or local public health authority(ies) are also authorized to make available additional information relating to the emergency use of the authorized rRT-PCR Swine Flu Panel that is consistent with, and does not exceed, the terms of this letter of authorization. I have concluded, pursuant to section 564(d)(2) of the Act, that it is reasonable to believe that the known and potential benefits of the authorized rRT-PCR Swine Flu Panel in the specified population, when used in the presumptive diagnosis of swine influenza A (H1N1) virus infection, outweigh the known and potential risks of such product. I have concluded, pursuant to section 564(d)(3) of the Act, based on the totality of scientific evidence available to FDA, that it is reasonable to believe that the authorized rRT-PCR Swine Flu Panel may be effective in the presumptive diagnosis of swine influenza A (H1N1) virus infection pursuant to section 564(c)(2)(A) of the Act. FDA has reviewed the scientific information available including the information supporting the conclusions described in Section I above, and concludes that the authorized rRT-PCR Swine Flu Panel, when used to presumptively diagnose swine influenza A (H1N1) virus infection in the specified population, meets the criteria set forth in section 564(c) of the Act concerning safety and potential effectiveness. The emergency use of the authorized rRT-PCR Swine Flu Panel under this EUA must be consistent with, and may not exceed, the terms of this letter, including the scope and the conditions of authorization set forth below. Subject to the terms of this EUA and under the circumstances set forth in the Secretary of HHS’s determination under section 564(b)(1)(C) described above and the Secretary of HHS’s corresponding declaration under section 564(b)(1), the rRT-PCR Swine Flu Panel described above is authorized to presumptively diagnose swine influenza A (H1N1) virus infection in human individuals who are diagnosed with influenza A caused by a virus not subtypeable by currently available FDA cleared devices. This EUA will cease to be effective when the declaration of emergency is terminated under section 564(b)(2) of the Act or when the EUA is revoked under section 564(g) of the Act. mstockstill on DSKH9S0YB1PROD with NOTICES III.

Besser, MD Acting Director Centers for Disease Control and Prevention 1600 Clifton Road, MS C-12 Atlanta, GA 30333 Clifton, Bldg. 1, Room 6430 Dear Dr. Besser: This letter is in response to your request that the Food and Drug Administration (FDA) issue an Emergency Use Authorization (EUA) for emergency use of the CDC1 Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA2) and Viral Culture (rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA)) as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection, pursuant to section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. § 360bbb-3) by public health and other qualified laboratories. The CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel (rRT-PCR Flu Panel) was cleared by FDA on September 30, 2008 for use with nasopharyngeal and/or nasal swab specimens. Because of issues of availability and adequacy of the cleared test associated with the need for testing additional specimen types, this letter authorizes the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) with specimen types and reagents in addition to those of the cleared test, as described below. The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is authorized as a first tier test for patient specimens with suspected 2009 H1N1 influenza virus and is an integral component of the testing algorithm for the rRT-PCR Swine Flu Panel authorized for use under an April 27, 2009 Emergency Use Authorization. On April 26, 2009, pursuant to section 564(b)(1)(C) of the Act (21 U.S.C. § 360bbb-3(b)(1)(C)), the Secretary of the Department of Health and Human Services (HHS) determined that there is a public health emergency under 42 U.S.C. § 247d that affects, or has a significant potential to affect, national security, and that involves a specified biological, chemical, radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such an agent or agents -- in this case, 2009 H1N1 influenza virus.3 Pursuant to section 564(b) of the Act (21 U.S.C. § 360bbb-3(b)), and on the basis of such determination, the Secretary of the Department of Health and Human Services then declared an emergency justifying the authorization of the emergency use of the CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA) and Viral Culture subject to the terms of any authorization issued under 21 U.S.C. § 360bbb-3(a). Having concluded that the criteria for issuance of this authorization under section 564(c) of the Act (21 U.S.C. § 360bbb-3(c)) are met, I am authorizing the emergency use of the CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA) and Viral Culture (rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA))4 as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) in individuals suspected of having a 2009 H1N1 influenza virus infection. The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is a first tier test because it should be used to test specimens from such individuals first. If the test result of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is positive for influenza A and negative for H1 (seasonal) and H3 subtypes, then the laboratory should test the specimen with the rRT-PCR Swine Flu Panel. I. Criteria for Issuance of Authorization I have concluded that the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection meets the criteria for issuance of an authorization under section 564(c) of the Act, because I have concluded that: (1) The recently isolated novel 2009 influenza A (H1N1), or swine flu, virus can cause influenza, a serious or life threatening disease or condition to humans infected by this virus; mstockstill on DSKH9S0YB1PROD with NOTICES (2) based on the totality of scientific evidence available to FDA, it is reasonable to believe that the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) may be effective as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), and/or dual NPS/TS swab specimens and nasal aspirates (NA) from patients with signs and symptoms of respiratory infection suspected of having a 2009 H1N1 influenza virus infection and/or from viral culture, and that the known and potential benefits of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA), when used as a first tier test in the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3), outweigh the known and potential risks of such products; and (3) there is no adequate, approved, and available alternative to the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), and/or dual NPS/TS swab specimens and nasal aspirates (NA) from patients with signs and symptoms of respiratory infection and/or from viral culture specimens suspected of having a 2009 H1N1 influenza virus infection.5 Therefore, I have concluded that the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection meets the above criteria for issuance of an authorization.

Scope of Authorization I have concluded, pursuant to section 564(d)(1) of the Act, that the scope of this authorization is limited to the use of the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection. The authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA): CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA) and Viral Culture is a panel of oligonucleotide primers and dual-labeled hydrolysis probes for use in the real-time RT-PCR assay on the ABI 7500 Fast Dx Real-Time PCR instrument for the in vitro qualitative detection of human influenza viral RNA in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), and/or dual NPS/TS swab specimens and nasal aspirates (NA) from patients with signs and symptoms of respiratory infection and/or from viral culture.6 The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) uses the same primer and probe sequences as the CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel as the device cleared under K080570 except that the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) authorized for emergency use also utilizes the AgPath-IDTM One-Step RT-PCR Kit Human amplification reagents. Assay principle • The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is used in real-time RT-PCR assays on the ABI 7500 Fast instruments. The primer and probe sets are designed for detection and subtyping of influenza A viruses. • One-step RT-PCR assays are one-tube assays that first reverse-transcribe specific Ribonucleic acid (RNA) templates into cDNA copies. The complementary deoxyribonucleic acid (cDNA) then undergoes a polymerase chain reaction (PCR) that utilizes a thermocyclic heating and cooling of the reaction to logarithmically amplify a specific region of DNA. The probe anneals to a specific target sequence located between the forward and reverse primers. During the extension phase of the PCR cycle, the 5’ nuclease activity of Taq polymerase degrades the probe, causing the reporter dye to separate from the quencher dye, generating a fluorescent signal. With each cycle, additional reporter dye molecules are cleaved from their respective probes, increasing the fluorescence intensity. Fluorescence intensity is monitored at each PCR cycle. • No template controls (NTCs) and positive template controls for all primer and probe sets are included in each run. An extraction control (HSC) provides a secondary negative control that validates the extraction procedure and reagent integrity. The RNase P assay serves as a control to ensure adequate RNA resulted from extraction of each clinical specimen and that no inhibitors were present in the specimen. RNA extracted from clinical samples contains human RNA. The RP primer and probe set targets the human ribonuclease P gene. Therefore, the level of the RNase P primer and probe set reaction reflects the relative amount of human RNA recovered from the specimen and its suitability for clinical testing. The above rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA), when labeled consistent with the attached template, is authorized to be distributed to public health and other qualified laboratories7 under this EUA, despite the fact that it does not meet certain requirements otherwise required by federal law. The following written information pertaining to the emergency use of the authorized rRT-PCR Swine Flu Panel is authorized to be made available to health care providers and patients: • Fact Sheet For Healthcare Providers: Interpreting rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) Test Results • Fact Sheet For Patients: Understanding rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) Kit Test Results See attached. As described in section IV below, CDC and the appropriate state and/or local public health authority(ies) are also authorized to make available additional information relating to the emergency use of the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) that is consistent with, and does not exceed, the terms of this letter of authorization. mstockstill on DSKH9S0YB1PROD with NOTICES I have concluded, pursuant to section 564(d)(2) of the Act, that it is reasonable to believe that the known and potential benefits of the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) in the specified population, when used as a first tier test in the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection, outweigh the known and potential risks of such product. I have concluded, pursuant to section 564(d)(3) of the Act, based on the totality of scientific evidence available to FDA, that it is reasonable to believe that the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) may be effective as a first tier test in the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection pursuant to section 564(c)(2)(A) of the Act. FDA has reviewed the scientific information available including the information supporting the conclusions described in Section I above, and concludes that the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA), when used for qualitative detection of influenza virus types A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) from individuals suspected of having a 2009 H1N1 influenza virus infection in the specified population, meets the criteria set forth in section 564(c) of the Act concerning safety and potential effectiveness.

SUPPLEMENTARY INFORMATION:

I. Background

    Section 564 of the act (21 U.S.C. 360bbb-3), as amended by the 
Project BioShield Act of 2004 (Public Law 108-276), allows FDA to 
strengthen the public health protections against biological, chemical, 
nuclear, and radiological agents. Among other things, section 564 of 
the act allows FDA to authorize the use of an unapproved medical 
product or an unapproved use of an approved medical product during a 
public health emergency that affects, or has a significant potential to 
affect, national security, and that involves biological, chemical, 
radiological, or nuclear agent or agents, or a specified disease or 
condition that may be attributable to such agent or agents. With this 
EUA authority, FDA can help assure that medical countermeasures may be 
used in an emergency to diagnose, treat, or prevent serious or life-
threatening diseases or conditions caused by such agents, when there 
are no adequate, approved, and available alternatives.
    Section 564(b)(1) of the act provides that, before an EUA may be 
issued, the Secretary must declare an emergency justifying the 
authorization based on one of the following grounds: ``(A) a 
determination by the Secretary of Homeland Security that there is a 
domestic emergency, or a significant potential for a domestic 
emergency, involving a heightened risk of attack with a specified 
biological, chemical, radiological, or nuclear agent or agents; (B) a 
determination by the Secretary of Defense that there is a military 
emergency, or a significant potential for a military emergency, 
involving a heightened risk to United States military forces of attack 
with a specified biological, chemical, radiological, or nuclear agent 
or agents; or (C) a determination by the Secretary of a public health 
emergency under section 319 of the Public Health Service Act that 
affects, or has a significant potential to affect, national security, 
and that involves a specified biological, chemical, radiological, or 
nuclear agent or agents, or a specified disease or condition that may 
be attributable to such agent or agents.''
    Once the Secretary has declared an emergency justifying an 
authorization under section 564 of the act, FDA may authorize the 
emergency use of a drug, device, or biological product if the agency 
concludes that the statutory criteria are satisfied. Under section 
564(h)(1) of the act, FDA is required to publish, in the Federal 
Register, a notice of each authorization, and each termination or 
revocation of an authorization, and an explanation of the reasons for 
the action. Section 564 of the act permits FDA to authorize the 
introduction into interstate commerce of a drug, device, or biological 
product intended for use in a declared emergency. Products appropriate 
for emergency use may include products and uses that are not approved, 
cleared, or licensed under sections 505, 510(k), and 515 of the act (21 
U.S.C. 355, 360(k), and 360e) or section 351 of the PHS Act (42 U.S.C. 
262). FDA may issue an EUA only if, after consultation with the 
National Institutes of Health and CDC (to the extent feasible and 
appropriate given the circumstances of the emergency), FDA\1\ 
concludes: (1) That an agent specified in a declaration of emergency 
can cause a serious or life-threatening disease or condition; (2) that, 
based on the totality of scientific evidence available to FDA, 
including data from adequate and well-controlled clinical trials, if 
available, it is reasonable to believe that: (A) the product may be 
effective in diagnosing, treating, or preventing--(1) such disease or 
condition; or (2) a serious or life-threatening disease or condition 
caused by a product authorized under Section 564, approved or cleared 
under this Act, or licensed under Section 351 of the Public Health 
Service Act (PHS Act), for diagnosing, treating, or preventing such a 
disease or condition caused by such an agent; and (B) the known and 
potential benefits of the product, when used to diagnose, prevent, or 
treat such disease or condition, outweigh the known and potential risks 
of the product; (3) that there is no adequate, approved, and available 
alternative to the product for diagnosing, preventing, or treating such 
disease or condition; and (4) that such other criteria as the Secretary 
may by regulation prescribe are satisfied.
---------------------------------------------------------------------------

    \1\ The Secretary has delegated his authority to issue an EUA 
under section 564 of the act to the Commissioner of Food and Drugs.
---------------------------------------------------------------------------

    No other criteria of issuance have been prescribed by regulation 
under section 564(c)(4) of the act. Because the statute is self-
executing, FDA does not require regulations or guidance to implement 
the EUA authority. However, in the Federal Register of July 26, 2007 
(72 FR 41083), FDA announced the availability of a guidance entitled 
``Emergency Use Authorization of Medical Products.'' The guidance 
provides more information for stakeholders and the public about the EUA 
authority and the agency's process for the consideration of EUA 
requests.

II. EUA Request for Certain In Vitro Diagnostic Products

    On April 26, 2009, under section 564(b)(1)(C) of the act, the 
Acting Secretary determined that a public health emergency exists 
involving Swine Influenza A (now known as 2009 H1N1 Influenza A or 2009 
H1N1 flu) that affects, or has the significant potential to affect, 
national security. On April 26, 2009, under section 564(b) of the act, 
and on the basis of such determination, the Acting Secretary declared 
an emergency justifying the authorization of certain in vitro 
diagnostics for detection of Swine Influenza A (2009 H1N1 flu virus), 
accompanied by emergency use information subject to the terms of any 
authorization issued under 21 U.S.C. 360bbb-3(a). Notice of the 
determination and the declaration of the Acting Secretary is published 
elsewhere in this issue of the Federal Register.
    On April 27, 2009, in response to a CDC request, FDA issued an EUA 
for the Swine Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR 
Swine Flu Panel) with certain written

[[Page 38638]]

information, including fact sheets for healthcare providers and 
patients and adequate directions for use, which are authorized under 
the EUA. On May 2, 2009, in response to a CDC request to allow use of 
the rRT-PCR Swine Flu Panel for different sample types and different 
reagents, FDA amended the rRT-PCR Swine Flu Panel Authorization letter 
and reissued the Authorization letter in its entirety, with amended 
written information, including adequate directions for use. In 
addition, on May 2, 2009, in response to a CDC request, FDA issued an 
EUA with certain written information, including adequate directions for 
use, to allow the use of the FDA-cleared in vitro diagnostic device, 
CDC Human Influenza Virus Real-time RT-PCR Detection and 
Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, 
NA2) and Viral Culture) (CDC rRT-PCR flu panel), for patient specimen 
types and reagents in addition to those of the cleared CDC rRT-PCR flu 
panel.

 Atlanta, GA 30333
 Clifton, Bldg. 1, Room 6430
 
 
 Dear Dr. Besser:
 
 On April 27, 2009, FDA issued a letter authorizing the emergency use of the Swine Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR Swine Flu Panel) for the presumptive diagnosis of
 swine influenza A (H1N1), pursuant to section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. Sec.   360bbb-3) by public health and other qualified laboratories. On May
 1, 2009, CDC submitted a request for an amendment to the Emergency Use Authorization. In response to that request, the letter authorizing emergency use of the rRT-PCR Swine Flu Panel is being
 reissued in its entirety with the amendments, as requested by CDC, incorporated.\1\
 
 On April 26, 2009, pursuant to section 564(b)(1)(C) of the Act (21 U.S.C. Sec.   360bbb-3(b)(1)(C)), the Secretary of the Department of Health and Human Services (HHS) determined that there
 is a public health emergency under 42 U.S.C. Sec.   247d that affects, or has a significant potential to affect, national security, and that involves a specified biological, chemical,
 radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such an agent or agents -- in this case, swine influenza A (H1N1).\2\ Pursuant to
 section 564(b) of the Act (21 U.S.C. Sec.   360bbb-3(b)), and on the basis of such determination, the Secretary of the Department of Health and Human Services then declared an emergency
 justifying the authorization of the emergency use of the Swine Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR Swine Flu Panel) subject to the terms of any authorization issued
 under 21 U.S.C. Sec.   360bbb-3(a).
 
 Having concluded that the criteria for issuance of this authorization under section 564(c) of the Act (21 U.S.C. Sec.   360bbb-3(c)) are met, I am authorizing the emergency use of the Swine
 Influenza Virus Real-time RT-PCR Detection Panel (rRT-PCR Swine Flu Panel)\3\ for the presumptive diagnosis of swine influenza A (H1N1) virus infection in human individuals who have been
 diagnosed with influenza A caused by a virus not subtypeable by currently available FDA-cleared devices, subject to the terms of this authorization.
 
 I. Criteria for Issuance of Authorization
 
 I have concluded that the emergency use of the rRT-PCR Swine Flu Panel for the presumptive diagnosis of swine influenza A (H1N1) virus infection for human individuals who are diagnosed with
 influenza A caused by a virus that is not subtypeable by currently available FDA-cleared devices meets the criteria for issuance of an authorization under section 564(c) of the Act, because I
 have concluded that:
 
    (1) The recently isolated novel 2009 influenza A (H1N1), or swine flu, virus can cause influenza, a serious or life threatening disease or condition to humans infected by this virus;
 
    (2) based on the totality of scientific evidence available to FDA, it is reasonable to believe that the rRT-PCR Swine Flu Panel may be effective in the presumptive diagnosis of swine
     influenza A (H1N1) virus infection, and that the known and potential benefits of the rRT-PCR Swine Flu Panel, when used in the presumptive diagnosis of swine influenza A (H1N1) virus
     infection, outweigh the known and potential risks of such products; and
 
    (3) there is no adequate, approved, and available alternative to the emergency use of the rRT-PCR Swine Flu Panel for the presumptive diagnosis of swine influenza A (H1N1) virus
     infection.\4\
 
 Therefore, I have concluded that the emergency use of the rRT-PCR Swine Flu Panel for the presumptive diagnosis of swine influenza A (H1N1) virus infection in human individuals who are
 diagnosed with influenza A infections not subtypeable by currently available FDA-cleared devices meets the above criteria for issuance of an authorization.
 
 II. Scope of Authorization
 

[[Page 38639]]

 
 I have concluded, pursuant to section 564(d)(1) of the Act, that the scope of this authorization is limited to the use of the authorized rRT-PCR Swine Flu Panel for the presumptive diagnosis
 of 2009 H1N1 influenza A virus infection for individuals who are diagnosed with influenza A caused by a virus not subtypeable by currently available FDA-cleared devices.
 
 The authorized rRT-PCR Swine Flu Panel is as follows:
 
 The Swine Influenza Virus Real-time RT-PCR Detection Panel is a panel of oligonucleotide primers and dual-labeled hydrolysis (Taqman[reg]) probes for use in the real-time RT-PCR assay on the
 ABI 7500 Fast Dx Real-Time PCR instrument for the in vitro qualitative detection of 2009 H1N1 influenza viral RNA in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/
 TS swab, or nasal aspirate (NA) specimens from patients with signs and symptoms of respiratory infection and viral culture. The universal 2009 H1N1 influenza swInfA (NP gene) and swH1 (HA
 gene) primer and probe sets are designed for detection of 2009 A/H1N1 influenza viruses. In addition rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) authorized for emergency use utilizes the
 AgPath-ID\TM\ One-Step RT-PCR Kit Human amplification reagents.
 
 The rRT-PCR Swine Flu Panel includes the following primer and probe sets:
     InfA detects universal influenza A strains in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/TS swab, or nasal aspirate (NA) specimens from patients
     with signs and symptoms of respiratory infection, and virus culture.
     swInfA specifically detects swine influenza A strains (NP gene) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/TS swab, or nasal aspirate (NA)
     specimens from patients with signs and symptoms of respiratory infection, and virus culture.
     swH1 is specific for swine influenza A, subtype H1 (HA gene) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), dual NPS/TS swab, or nasal aspirate (NA) specimens
     from patients with signs and symptoms of respiratory infection, and viral culture.
 
 The rRT-PCR Swine Flu Panel also includes control materials:
     RNase P (RP) detects human RNase P and is used as a positive control with human clinical specimens to indicate that adequate isolation of nucleic acid resulted from the extraction
     of the clinical specimen.
     Swine Influenza Panel Real-Time RT-PCR Positive Control (SIPC) is a positive control designed to react with all the primer and probe sets including RNase P.
 
 The above rRT-PCR Swine Flu Panel, when labeled consistent with the attached template is authorized to be distributed to public health and other qualified laboratories\5\ under this EUA,
 despite the fact that it does not meet certain requirements otherwise required by federal law.
 
 The following written information pertaining to the emergency use of the authorized rRT-PCR Swine Flu Panel is authorized to be made available to health care providers and patients:
 
     Fact Sheet For Healthcare Providers: Interpreting Swine Influenza Rt-Pcr Detection Panel Test Results

 to the emergency use of the authorized rRT-PCR Swine Flu Panel that is consistent with, and does not exceed, the terms of this letter of authorization.
 
 I have concluded, pursuant to section 564(d)(2) of the Act, that it is reasonable to believe that the known and potential benefits of the authorized rRT-PCR Swine Flu Panel in the specified
 population, when used in the presumptive diagnosis of swine influenza A (H1N1) virus infection, outweigh the known and potential risks of such product.
 
 I have concluded, pursuant to section 564(d)(3) of the Act, based on the totality of scientific evidence available to FDA, that it is reasonable to believe that the authorized rRT-PCR Swine
 Flu Panel may be effective in the presumptive diagnosis of swine influenza A (H1N1) virus infection pursuant to section 564(c)(2)(A) of the Act. FDA has reviewed the scientific information
 available including the information supporting the conclusions described in Section I above, and concludes that the authorized rRT-PCR Swine Flu Panel, when used to presumptively diagnose
 swine influenza A (H1N1) virus infection in the specified population, meets the criteria set forth in section 564(c) of the Act concerning safety and potential effectiveness.
 
 The emergency use of the authorized rRT-PCR Swine Flu Panel under this EUA must be consistent with, and may not exceed, the terms of this letter, including the scope and the conditions of
 authorization set forth below. Subject to the terms of this EUA and under the circumstances set forth in the Secretary of HHS's determination under section 564(b)(1)(C) described above and
 the Secretary of HHS's corresponding declaration under section 564(b)(1), the rRT-PCR Swine Flu Panel described above is authorized to presumptively diagnose swine influenza A (H1N1) virus
 infection in human individuals who are diagnosed with influenza A caused by a virus not subtypeable by currently available FDA cleared devices.
 This EUA will cease to be effective when the declaration of emergency is terminated under section 564(b)(2) of the Act or when the EUA is revoked under section 564(g) of the Act.

 Acting Director
 Centers for Disease Control and Prevention
 1600 Clifton Road, MS C-12
 Atlanta, GA 30333
 Clifton, Bldg. 1, Room 6430
 
 
 Dear Dr. Besser:
 This letter is in response to your request that the Food and Drug Administration (FDA) issue an Emergency Use Authorization (EUA) for emergency use of the CDC\1\ Human Influenza Virus Real-
 time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA\2\) and Viral Culture (rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA)) as a first tier test
 for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009
 H1N1 influenza virus infection, pursuant to section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. Sec.   360bbb-3) by public health and other qualified laboratories.
 
 The CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel (rRT-PCR Flu Panel) was cleared by FDA on September 30, 2008 for use with nasopharyngeal and/or nasal swab
 specimens. Because of issues of availability and adequacy of the cleared test associated with the need for testing additional specimen types, this letter authorizes the emergency use of the
 rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) with specimen types and reagents in addition to those of the cleared test, as described below. The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is
 authorized as a first tier test for patient specimens with suspected 2009 H1N1 influenza virus and is an integral component of the testing algorithm for the rRT-PCR Swine Flu Panel authorized
 for use under an April 27, 2009 Emergency Use Authorization.
 
 On April 26, 2009, pursuant to section 564(b)(1)(C) of the Act (21 U.S.C. Sec.   360bbb-3(b)(1)(C)), the Secretary of the Department of Health and Human Services (HHS) determined that there
 is a public health emergency under 42 U.S.C. Sec.   247d that affects, or has a significant potential to affect, national security, and that involves a specified biological, chemical,
 radiological, or nuclear agent or agents, or a specified disease or condition that may be attributable to such an agent or agents -- in this case, 2009 H1N1 influenza virus.\3\ Pursuant to
 section 564(b) of the Act (21 U.S.C. Sec.   360bbb-3(b)), and on the basis of such determination, the Secretary of the Department of Health and Human Services then declared an emergency
 justifying the authorization of the emergency use of the CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA)
 and Viral Culture subject to the terms of any authorization issued under 21 U.S.C. Sec.   360bbb-3(a).
 
 Having concluded that the criteria for issuance of this authorization under section 564(c) of the Act (21 U.S.C. Sec.   360bbb-3(c)) are met, I am authorizing the emergency use of the CDC
 Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA) and Viral Culture (rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS,
 NA))\4\ as a first tier test for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) in individuals
 suspected of having a 2009 H1N1 influenza virus infection. The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is a first tier test because it should be used to test specimens from such
 individuals first. If the test result of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is positive for influenza A and negative for H1 (seasonal) and H3 subtypes, then the laboratory should
 test the specimen with the rRT-PCR Swine Flu Panel.
 
 I. Criteria for Issuance of Authorization
 
 I have concluded that the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as a first tier test for the qualitative detection of influenza virus type A or B and subtype
 determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection meets the criteria for issuance of an
 authorization under section 564(c) of the Act, because I have concluded that:
    (1) The recently isolated novel 2009 influenza A (H1N1), or swine flu, virus can cause influenza, a serious or life threatening disease or condition to humans infected by this virus;
 
    (2) based on the totality of scientific evidence available to FDA, it is reasonable to believe that the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) may be effective as a first tier test
     for the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) in nasopharyngeal swabs (NPS), nasal
     swabs (NS), throat swabs (TS), and/or dual NPS/TS swab specimens and nasal aspirates (NA) from patients with signs and symptoms of respiratory infection suspected of having a 2009 H1N1
     influenza virus infection and/or from viral culture, and that the known and potential benefits of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA), when used as a first tier test in the
     qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3), outweigh the known and potential risks of such
     products; and
 
    (3) there is no adequate, approved, and available alternative to the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as a first tier test for the qualitative detection of
     influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) in nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), and/
     or dual NPS/TS swab specimens and nasal aspirates (NA) from patients with signs and symptoms of respiratory infection and/or from viral culture specimens suspected of having a 2009 H1N1
     influenza virus infection.\5\
 
 Therefore, I have concluded that the emergency use of the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as a first tier test for the qualitative detection of influenza virus type A or B and
 subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection meets the above criteria for
 issuance of an authorization.

[[Page 38642]]

 
 
 II. Scope of Authorization
 
 I have concluded, pursuant to section 564(d)(1) of the Act, that the scope of this authorization is limited to the use of the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) for the
 qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1
 influenza virus infection.
 
 The authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA):
 
 CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA) and Viral Culture is a panel of oligonucleotide primers and
 dual-labeled hydrolysis probes for use in the real-time RT-PCR assay on the ABI 7500 Fast Dx Real-Time PCR instrument for the in vitro qualitative detection of human influenza viral RNA in
 nasopharyngeal swabs (NPS), nasal swabs (NS), throat swabs (TS), and/or dual NPS/TS swab specimens and nasal aspirates (NA) from patients with signs and symptoms of respiratory infection and/
 or from viral culture.\6\
 
 The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) uses the same primer and probe sequences as the CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel as the device
 cleared under K080570 except that the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) authorized for emergency use also utilizes the AgPath-ID\TM\ One-Step RT-PCR Kit Human amplification
 reagents.
 
 Assay principle
 
     The rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) is used in real-time RT-PCR assays on the ABI 7500 Fast instruments. The primer and probe sets are designed for detection and
     subtyping of influenza A viruses.
 
     One-step RT-PCR assays are one-tube assays that first reverse-transcribe specific Ribonucleic acid (RNA) templates into cDNA copies. The complementary deoxyribonucleic acid (cDNA)
     then undergoes a polymerase chain reaction (PCR) that utilizes a thermocyclic heating and cooling of the reaction to logarithmically amplify a specific region of DNA. The probe anneals to
     a specific target sequence located between the forward and reverse primers. During the extension phase of the PCR cycle, the 5' nuclease activity of Taq polymerase degrades the probe,
     causing the reporter dye to separate from the quencher dye, generating a fluorescent signal. With each cycle, additional reporter dye molecules are cleaved from their respective probes,
     increasing the fluorescence intensity. Fluorescence intensity is monitored at each PCR cycle.
 
     No template controls (NTCs) and positive template controls for all primer and probe sets are included in each run. An extraction control (HSC) provides a secondary negative
     control that validates the extraction procedure and reagent integrity. The RNase P assay serves as a control to ensure adequate RNA resulted from extraction of each clinical specimen and
     that no inhibitors were present in the specimen. RNA extracted from clinical samples contains human RNA. The RP primer and probe set targets the human ribonuclease P gene. Therefore, the
     level of the RNase P primer and probe set reaction reflects the relative amount of human RNA recovered from the specimen and its suitability for clinical testing.
 
 The above rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA), when labeled consistent with the attached template, is authorized to be distributed to public health and other qualified laboratories\7\
 under this EUA, despite the fact that it does not meet certain requirements otherwise required by federal law.
 
 The following written information pertaining to the emergency use of the authorized rRT-PCR Swine Flu Panel is authorized to be made available to health care providers and patients:
 
     Fact Sheet For Healthcare Providers: Interpreting rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) Test Results
     Fact Sheet For Patients: Understanding rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) Kit Test Results
 
 See attached. As described in section IV below, CDC and the appropriate state and/or local public health authority(ies) are also authorized to make available additional information relating
 to the emergency use of the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) that is consistent with, and does not exceed, the terms of this letter of authorization.
 
 I have concluded, pursuant to section 564(d)(2) of the Act, that it is reasonable to believe that the known and potential benefits of the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS,
 NA) in the specified population, when used as a first tier test in the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus
 (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection, outweigh the known and potential risks of such product.
 
 I have concluded, pursuant to section 564(d)(3) of the Act, based on the totality of scientific evidence available to FDA, that it is reasonable to believe that the authorized rRT-PCR Flu
 Panel (NPS, NS, TS, NPS/TS, NA) may be effective as a first tier test in the qualitative detection of influenza virus type A or B and subtype determination of seasonal human influenza A virus
 (seasonal A/H1 or A/H3) for individuals suspected of having a 2009 H1N1 influenza virus infection pursuant to section 564(c)(2)(A) of the Act. FDA has reviewed the scientific information
 available including the information supporting the conclusions described in Section I above, and concludes that the authorized rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA), when used for
 qualitative detection of influenza virus types A or B and subtype determination of seasonal human influenza A virus (seasonal A/H1 or A/H3) from individuals suspected of having a 2009 H1N1
 influenza virus infection in the specified population, meets the criteria set forth in section 564(c) of the Act concerning safety and potential effectiveness.

\4\ FDA is authorizing the emergency use of the CDC Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel for Respiratory Specimens (NPS, NS, TS, NPS/TS, NA) and Viral
  Culture (rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) as described in the scope section of this letter (Section II). For ease of reference, this letter will use the term the ``rRT-PCR Flu
  Panel (NPS, NS, TS, NPS/TS, NA).''
\5\ The cleared test for in vitro qualitative detection of human influenza viral RNA (The CDC rRT-PCR Flu Panel (IVD) 510(K) 080570) is not adequate because of the need to test additional
  types of samples during this emergency and it is not sufficiently available because of limited availability of certain reagents. No other criteria of issuance have been prescribed by
  regulation under section 564(c)(4) of the Act.
\6\ The CDC rRT-PCR Flu Panel (IVD) 510(K) 080570 is indicated for the in vitro qualitative detection of human influenza viral RNA in nasopharyngeal swabs (NPS) and nasal swabs (NS) only.
\7\ All users, analysts, and any person reporting diagnostic results from use of this device should be trained to perform and interpret the results from this procedure by a CDC instructor or
  designee prior to use. CDC Influenza Division will limit the distribution of this device to those users who have successfully completed training provided by CDC instructors or designees. Use
  is limited to designated laboratories that are qualified to receive and use the CDC rRT-PCR Flu Panel (IVD) 510(K) 080570. See ``Conditions of Authorization'' below.
\8\ These requirements are waived only for the rRT-PCR Flu Panel (NPS, NS, TS, NPS/TS, NA) that is authorized for emergency use. These requirements, and all other applicable statutory and
  regulatory requirements, continue to apply to the CDC rRT-PCR Flu Panel (IVD) 510(K) 080570.
