[Docket No. FDA-2009-N-0521]

 
Authorization of Emergency Use of the Antiviral Product Peramivir 
Accompanied by Emergency Use Information; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
issuance of an Emergency Use Authorization (EUA) (the Authorization) 
for peramivir 200 milligrams (mg)/20 milliliter (mL) (10 mg/mL) single 
use vial manufactured for BioCryst Pharmaceuticals, Inc. (BioCryst) for 
intravenous (IV) administration in certain adult and pediatric 
patients. Peramivir is a drug that is not approved by FDA. FDA is 
issuing the Authorization under the Federal Food, Drug, and Cosmetic 
Act (the act), as requested by the Centers for Disease Control and 
Prevention (CDC). The Authorization contains, among other things, 
conditions on the emergency use of peramivir. The Authorization follows 
the determination by then Acting Secretary of the U.S. Department of 
Health and Human Services Charles E. Johnson (then Acting Secretary) 
that a public health emergency exists involving Swine Influenza A (now 
known as ``2009-H1N1 Influenza'') that affects, or has the significant 
potential to affect, national security. The determination has been 
renewed. On the basis of such determination, the Secretary declared an 
emergency justifying the authorization of the emergency use of the 
antiviral peramivir, accompanied by emergency use information, subject 
to the terms of any authorization issued under the act. The 
Authorization, which includes an explanation of the reasons for 
issuance, is reprinted in this document. The notice of the declaration 
of the Secretary is announced elsewhere in this issue of the Federal 
Register.

DATES: The Authorization is effective as of October 23, 2009.

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 (PHS 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 (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 her 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 published a notice of availability of a guidance 
entitled ``Emergency Use Authorization of Medical Products'' to provide 
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 Peramivir

    On April 26, 2009, under section 564(b)(1)(C) of the act (21 U.S.C. 
360bbb-3(b)(1)(C)), the then Acting Secretary determined that a public 
health emergency exists involving Swine Influenza A (now known as 2009-
H1N1 influenza) that affects, or has the significant potential to 
affect, national security. The declaration has been renewed. On October 
20, 2009, under section 564(b) of the act, and on the basis of such 
determination, the Secretary declared an emergency justifying the 
authorization of the emergency use of the antiviral peramivir, 
accompanied by emergency use information, subject to the terms of any 
authorization issued under 21 U.S.C. 360bbb-3(a). Notice of the 
declaration of the Secretary is published elsewhere in this issue of 
the Federal Register. On October 23, 2009, CDC requested and FDA issued 
the EUA for peramivir 200 mg/ 20 mL (10 mg/mL) single use vial 
manufactured for BioCryst for IV administration in certain adult and 
pediatric patients, accompanied by emergency use instructions, subject 
to the terms and conditions of the authorization.

IV. The Authorization

    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 peramivir 200 mg/ 20 mL (10 mg/mL) 
single use vial manufactured for BioCryst for IV administration in 
certain adult and pediatric patient, accompanied by emergency use 
information, subject to the terms and conditions of the authorization.
    The Authorization for peramivir 200 mg/ 20 mL (10 mg/mL) single use 
vial manufactured for BioCryst for IV administration follows and 
provides an explanation of the reasons for its issuance, as required by 
section 564(h)(1) of the act:

                   October 23, 2009

 Thomas R. Frieden, MD, MPH
 Director
 Centers for Disease Control and Prevention
 1600 Clifton Rd, MS D-14
 Atlanta, GA 30333

 Dear Dr. Frieden:

 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 the unapproved drug peramivir
 administered intravenously for treatment of 2009 H1N1 influenza virus (hereafter ``2009 H1N1'') in certain adult and pediatric patients, pursuant to section 564 of the Federal Food, Drug, and
 Cosmetic Act (the Act) (21 U.S.C. Sec.   360bbb-3).

 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 then Acting Secretary of the Department of Health and Human Services (DHHS) determined
 that a public health emergency exists involving Swine Influenza A (now referred to as ``2009 H1N1'') that affects or has significant potential to affect national security. The Secretary has
 renewed the determination. 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 declared an emergency justifying
 the authorization of the emergency use of the antiviral peramivir, accompanied by emergency use information, subject to the terms of any authorization issued under section 564(a) of the Act
 (21 U.S.C. Sec.   360bbb-3(a)).

 Having consulted with the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH), and 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 peramivir\1\ administered intravenously for treatment of 2009 H1N1
 in certain adult and pediatric patients, subject to the terms of this authorization.

 I. Criteria for Issuance of Authorization

 I have concluded that the emergency use of peramivir administered intravenously for treatment of 2009 H1N1 in certain adult and pediatric patients meets the criteria for issuance of an
 authorization under section 564(c) of the Act, because I have concluded that:

    (1) 2009 H1N1 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 peramivir may be effective when administered intravenously for the treatment of 2009
     H1N1 in certain adult and pediatric patients, and that the known and potential benefits of peramivir, when administered intravenously for the treatment of 2009 H1N1 in certain adult and
     pediatric patients, outweigh the known and potential risks of peramivir; and

    (3) there is no adequate, approved, and available alternative to the emergency use of peramivir administered intravenously for the treatment of 2009 H1N1 in certain adult and pediatric
     patients.\2\

 Therefore, I have concluded that the emergency use of peramivir administered intravenously for the treatment of 2009 H1N1 in certain adult and pediatric patients 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 emergency use of authorized peramivir for the treatment of 2009 H1N1 in
 certain adult and pediatric patients. The emergency use of authorized peramivir 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.

 Peramivir (a neuraminidase inhibitor) is an unapproved drug that it is currently being studied in clinical investigations. Peramivir is not currently approved by FDA for any use in the United
 States.

 The authorized peramivir is as follows:

     Peramivir injection: 200mg/20mL (10 mg/mL) single use vial manufactured for BioCryst Pharmaceuticals, Inc. (BioCryst). (See Section IV.D.3. of this letter).

 1. The above peramivir product is authorized only for intravenous (IV) administration.

 2. The above peramivir product is authorized for the treatment of certain patients with suspected or laboratory confirmed 2009 H1N1 infection or infection due to nonsubtypable influenza A
 virus suspected to be 2009 H1N1 based on community epidemiology. Specifically, the peramivir product is authorized only for the following patients who are admitted to a hospital and under the
 care or consultation of a licensed clinician (skilled in the diagnosis and management of patients with potentially life-threatening illness and the ability to recognize and manage medication-
 related adverse events):
    a. Adult patients for whom therapy with an IV agent is clinically appropriate, based upon one or more of the following reasons:
      (i) patient not responding to either oral or inhaled antiviral therapy, or
      (ii) drug delivery by a route other than IV (e.g., enteral oseltamivir or inhaled zanamivir) is not expected to be dependable or is not feasible, or
      (iii) the clinician judges IV therapy is appropriate due to other circumstances.
    b. Pediatric patients for whom an IV agent is clinically appropriate because:
      (i) patient not responding to either oral or inhaled antiviral therapy, or

[[Page 56647]]


      (ii) drug delivery by a route other than IV (e.g., enteral oseltamivir or inhaled zanamivir) is not expected to be dependable or is not feasible).

 3. The above peramivir product may only include product distributed from Strategic National Stockpile (SNS), in which case such product is authorized only to be labeled with the attached
 label.

 4. The above peramivir product is authorized to be accompanied by the following written information pertaining to the emergency use, which is attached and authorized to be made available to
 health care providers and patients (and parents/caregivers):

       Fact Sheet for Health Care Provider
       Fact Sheet for Patients and Parents/Caregivers

 CDC, hospitals, and health care providers receiving authorized peramivir are also authorized to make available additional written information relating to the emergency use of authorized
 peramivir that is consistent with and does not exceed the terms of this letter of authorization (including the above referenced facts sheets).

 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 peramivir, when used for the treatment of H1N1
 in certain adult and pediatric patients, 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 peramivir may
 be effective for the treatment of 2009 H1N1 in certain adult and pediatric patients 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 of this letter above, and concludes that the authorized peramivir when used for the treatment of 2009 H1N1 in
 certain adult and pediatric patients, meets the criteria set forth in section 564(c) of the Act concerning safety and potential effectiveness.

 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 peramivir described above is authorized for the treatment of 2009 H1N1 in certain adult and pediatric patients.

 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

 This letter covers authorized peramivir as previously manufactured for BioCryst as of the date of this letter as well as authorized peramivir that may be manufactured for BioCryst after such
 date, insofar as FDA has determined that the methods used in, and the facilities and controls used for, the manufacturing, processing and packing of authorized peramivir are adequate to
 preserve its identity, strength, quality and purity.

 Authorized peramivir should be held in accordance with its labeled and appropriate product storage conditions (ambient temperature, 15[deg]C-30[deg]C or 59[deg]F-86[deg]F). However, in order
 to ensure the delivery and availability of authorized peramivir, I am waiving current good manufacturing practice (CGMP) requirements with respect to proper storage conditions of temperature
 during the shipment and holding of authorized peramivir by CDC and/or its designees for a maximum of 90 days (consecutive or non-consecutive) from the date of shipment to CDC and/or its
 designees. Significant excursions from labeled storage conditions should be documented to the extent practicable given the circumstances of the emergency, and need not be supported by
 additional testing by CDC or its designees.?

 IV. Conditions of Authorization

 Pursuant to section 564 of the Act, I am establishing the following conditions on this authorization:

  A. CDC

  A.1. CDC will decide how authorized peramivir will be distributed under its direction to Hospitals upon request by licensed treating clinicians at the Hospitals to the extent such decisions
   are consistent with and do not exceed the terms of this letter; except that CDC will ensure that authorized peramivir will be distributed to Hospitals as soon as possible within 24 hours of
   CDC's decision to distribute such product, to the extent practicable given the circumstances of the emergency.

  A.2. CDC will maintain adequate records regarding distribution under its direction of authorized peramivir (i.e., lot numbers, quantity, receiving site, receipt date, unique identifier(s)
   (e.g., Peramivir Request number(s))).

  A.3. CDC will notify FDA on a weekly basis (unless otherwise specified by FDA) of the quantity of and to which Hospitals authorized peramivir is distributed under its direction. CDC will
   also include in the notification the unique identifier(s) (e.g., Peramivir Request number(s)).

  A.4. CDC will ensure that authorized peramivir is distributed for use under its direction only within the expiry dates identified by FDA. CDC will inform Hospitals receiving authorized
   peramivir under its direction of the expiry dates by which authorized peramivir is to be used if authorized peramivir is nearing expiry. CDC will maintain adequate records regarding the
   expiry dates by which authorized peramivir is to be used.

  A.5. CDC will ensure that Hospitals receiving authorized peramivir under its direction are informed of this letter, including the terms and conditions as well as any authorized amendments
   thereto.


[[Page 56648]]
