DEPARTMENT OF HEALTH AND HUMAN SERVICES
Food and Drug Administration
[Docket No. FDA-2009-N-0276]
Authorizations of Emergency Use of Certain Antiviral Drugs--
Zanamivir and Oseltamivir Phosphate; Availability
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) for certain products from the neuraminidase class of
antivirals--Zanamivir and oseltamivir phosphate. FDA is issuing the
Authorizations under the Federal Food, Drug, and Cosmetic Act (the
act), as requested by the Centers for Disease Control and Prevention
(CDC). The Authorizations contain, among other things, conditions on
the emergency use of the authorized zanamivir and oseltamivir phosphate
products. 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 products from the neuraminidase class of
antivirals--Zanamivir and oseltamivir phosphate, accompanied by
emergency use information subject to the terms of any authorization
issued under the act. 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 in vitro diagnostic devices and the issuance of an
EUA for certain personal respiratory protection devices.
DATES: The Authorizations are effective as of April 27, 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.
Send one self-addressed adhesive label to assist that office in
processing your request or include a fax number to which the
Authorization(s) may be sent. See the SUPPLEMENTARY INFORMATION section
for electronic access to the Authorizations.
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:
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
[[Page 38649]]
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 Public Health
Service Act (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 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 Products From the Neuraminidase Class of
Antivirals, Zanamivir and Oseltamivir Phosphate
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 the emergency use of
certain products from the neuraminidase class of antivirals--Zanamivir
and oseltamivir phosphate, 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 26, 2009, CDC requested and, on April 27, 2009, FDA
issued EUAs for zanamivir inhalation powder and certain oseltamivir
phosphate capsules and oral suspension for the treatment and
prophylaxis of influenza, accompanied by emergency use instructions,
which are authorized under the EUAs. On April 27, 2009, FDA also
amended the EUAs for zanamivir and oseltamivir phosphate, including the
emergency use instructions authorized under the EUAs.
III. Electronic Access
An electronic version of this document and the full text of the
Authorizations are available on the Internet at http://
www.regulations.gov.
IV. The Authorizations
Having concluded that the criteria for issuance of the
Authorizations under section 564(c) of the act are met, FDA has
authorized the emergency use of certain zanamivir inhalation powder and
certain oseltamivir phosphate capsules and oral suspension for the
treatment and prophylaxis of influenza, accompanied by emergency use
information, subject to the terms and conditions of the authorizations.
The Authorization (as amended) for certain zanamivir inhalation
powder 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 Rd, MS D-14
Atlanta, GA 30333
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 the emergency use of zanamivir inhalation powder for
treatment and prophylaxis of influenza, pursuant to section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. Sec. 360bbb-3).
[[Page 38650]]
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 (DHHS) determined that a
public health emergency exists involving Swine Influenza A that affects or has significant potential to affect national security. 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 DHHS then declared an emergency justifying the authorization of the emergency use of certain zanamivir products subject
to the terms of any authorization issued under section 564(a) of the Act (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(b)) are met, I am authorizing the emergency use of certain
zanamivir products\1\ for the treatment and prophylaxis of influenza, subject to the terms of this authorization.
I. Criteria for Issuance of Authorization
I have concluded that the emergency use of certain zanamivir products for the treatment and prophylaxis of influenza meets the criteria for issuance of an authorization under section 564(c)
of the Act, because I have concluded that:
(1) Swine Influenza A can cause influenza, a serious or life-threatening disease or condition;
(2) based on the totality of scientific evidence available to FDA, it is reasonable to believe that certain zanamivir products may be effective for the treatment and prophylaxis of
influenza, and that the known and potential benefits of certain zanamivir products, when used for the treatment and prophylaxis of influenza, outweigh the known and potential risks of
such products; and
(3) there is no adequate, approved, and available alternative to the emergency use of certain zanamivir products for the treatment and prophylaxis of influenza.\2\
Therefore, I have concluded that the emergency use of certain zanamivir products for the treatment and prophylaxis of influenza meets the above statutory 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 authorized zanamivir products for the treatment and prophylaxis of
influenza for individuals exposed to Swine Influenza A. The emergency use of authorized zanamivir products 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.
The authorized zanamivir products are as follows:
Relenza (zanamivir) Inhalation Powder
Zanamivir products are approved and indicated for the treatment of uncomplicated acute illness due to influenza A and B virus in adults and pediatric patients 7 years of age and older who
have been symptomatic for no more than 2 days. Zanamivir products are also approved and indicated for prophylaxis of influenza in adults and pediatric patients 5 years of age and older.\3\
1. The above zanamivir products are authorized for use at later time points (i.e., patients who are symptomatic for more than 2 days) and/or in patients sick enough to require hospitalization
(i.e., patients who do not have ``uncomplicated acute illness'' per se).
2. The above zanamivir products labeled consistent with the manufacturer's label are authorized to be distributed under this EUA. Such products are authorized to be distributed or dispensed
without the requisite prescription label information under section 503(b)(2) of the Act (e.g., name and address of dispenser, serial number, date of prescription or of its filling, name of
prescriber, name of patient, if stated on prescription, directions for use and cautionary statements, if contained in the prescription).
3. The above zanamivir products are authorized to be accompanied by the following written information pertaining to the emergency use, which are authorized to be made available to health care
providers\4\ and recipients:
Fact Sheet for Health Care Provider
Fact Sheet for Recipients
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 authorized zanamivir
products that is consistent with, and does not exceed, the terms of this letter of authorization. (See section IV).
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 authorized zanamivir products, when used for the
treatment and prophylaxis of influenza, outweigh the known and potential risks of such products.
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 zanamivir
products may be effective for the treatment and prophylaxis of influenza 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 zanamivir products, when used for the treatment and prophylaxis of influenza in the
specified population, meet the criteria set forth in section 564(c) of the Act concerning safety and potential effectiveness.
[[Page 38651]]
Subject to the terms of this EUA and under the circumstances set forth in the Secretary of DHHS's determination under section 564(b)(1)(C) described above and the Secretary of DHHS's
corresponding declaration under section 564(b)(1), the zanamivir products described above are authorized for the treatment and prophylaxis of influenza for individuals exposed to Swine
Influenza A.
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. Current Good Manufacturing Practice
I am waiving current good manufacturing practice requirements with respect to the holding of authorized zanamivir products by CDC and other public health authority(ies) for a period of ninety
days.
IV. Conditions of Authorization
Pursuant to section 564 of the Act, I am establishing the following conditions on this authorization:

C. CDC will make available to the appropriate state and/or local public health authority(ies) through appropriate means the authorized Fact Sheet for Health Care Providers, authorized Fact
Sheet for Recipients, and at least one representative FDA-approved package insert that covers the dosage forms and strengths of authorized zanamivir products.
D. Only CDC may request changes to the authorized Fact Sheet for Health Care Providers and authorized Fact Sheet for Recipients. Such requests will be made by contacting FDA concerning FDA
review and approval.
State and/or Local Public Health Authority(ies)
E. The appropriate state and/or local public health authority(ies) will ensure that authorized zanamivir products are distributed to recipients in accordance with applicable state and local
laws and/or in accordance with the public health and medical emergency response of the Authority Having Jurisdiction to prescribe, administer, deliver, distribute, or dispense the covered
countermeasures, and their officials, agents, employees, contractors, or volunteers following a declaration of an emergency.
F. The appropriate state and/or local public health authority(ies) will make available through appropriate means authorized Fact Sheets for Health Care Providers, authorized Fact Sheets for
Recipients, and at least one representative FDA-approved package insert that covers the dosage forms and strengths of authorized zanamivir products.

Joshua M. Sharfstein, M.D.
Principal Deputy Commissioner
Acting Commissioner of Food and Drugs
\1\ FDA is authorizing the emergency use of Relenza (zanamivir) inhalation powder for treatment and prophylaxis of influenza as described in the scope section of this letter (Section II). For
ease of reference, this letter of authorization will use the terms ``certain zanamivir product(s)'' and ``authorized zanamivir product(s).''
\2\ No other criteria of issuance have been prescribed by regulation under section 564(c)(4) of the Act.
\3\ Zanamivir products are not recommended for treatment or prophylaxis of influenza in individuals with underlying airways disease (such as asthma or chronic obstructive pulmonary disease)
due to risk of serious bronchospasm. Zanamivir products have not been proven effective for treatment of influenza in individuals with underlying airways disease. Zanamivir products have not
been proven effective for prophylaxis of influenza in the nursing home setting. Zanamivir products are not a substitute for early vaccination on an annual basis as recommended by the Centers
for Disease Control and Prevention Advisory Committee on Immunization Practices. Influenza viruses change over time. Emergence of resistance mutations could decrease drug effectiveness.
Other factors (for example, changes in viral virulence) might also diminish clinical benefit of antiviral drugs. Prescribers should consider available information on influenza drug
susceptibility patterns and treatment effects when deciding whether to use zanamivir products. There is no evidence for efficacy of zanamivir in any illness caused by agents other than
Influenza A and B. Patients should be advised that the use of zanamivir products for treatment of influenza has not been shown to reduce the risk of transmission of influenza to others.
[[Page 38652]]
\4\ It is possible that public health officials or other volunteers might distribute authorized zanamivir products to recipients, if permitted, in accordance with applicable state and local
law and/or in accordance with the public health and medical emergency response of the Authority Having Jurisdiction to prescribe, administer, deliver, distribute, or dispense the covered
countermeasures, and their officials, agents, employees, contractors, or volunteers following a declaration of an emergency. For ease of reference, this letter will use the term ``health
care provider(s)'' to refer collectively to these individuals.
(Please note that certain written emergency use information was
also amended).
The Authorization (as amended) for certain oseltamivir phosphate
capsules and oral suspension follows and provides an explanation of the
reasons for its issuance, as required by section 564(h)(1) of the act:
