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.
The response burden for the six
participating sites and patients enrolled
in the study is estimated as:

AGENCY:
Food and Drug Administration,
HHS.
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

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.

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

issue an EUA under section 564 of the act to the
Commissioner of Food and Drugs.

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

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.

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.

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®) 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.

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:
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.

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-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

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.

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. 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.
III. Waiver of Certain Requirements
I am waiving the following requirements for the rRT-PCR Swine Flu Panel during the duration of this emergency use authorization:

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.
