SUPPLEMENTARY INFORMATION:

I. Amendment to the October 23, 2009, Authorization for Peramivir IV

    On April 26, 2009, under section 564(b)(1)(C) of the act (21 U.S.C. 
360bbb-3(b)(1)(C)), the Acting Secretary of Health and Human Services 
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. 
The determination of emergency 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). On October 23, 2009, 
in response to a request from CDC, FDA issued an EUA for the emergency 
use of the unapproved drug peramivir administered intravenously. On 
November 2, 2009, notice of the determination and declaration was 
published in the Federal Register (74 FR 56640, November 2, 2009), as 
was the notice of the Authorization (74 FR 56644, November 2, 2009). In 
response to inquiries about dosing of Peramivir IV in certain patients 
with severe renal impairment, including those who require continuous 
renal replacement therapy or hemodialysis, on November 19, 2009, FDA 
amended the Authorization letter to amend the Fact Sheet for Health 
Care Providers to provide additional clarification regarding the dosing 
recommendations for IV peramivir and reissued the Authorization letter 
in its entirety. The amended dosing recommendations are provided in the 
amended authorized version of the Fact Sheet for Health Care Providers.

II. Electronic Access

    An electronic version of this notice and the full text of the 
Authorization are available on the Internet at http://
www.regulations.gov.

III. The Authorization

    Having concluded that the criteria for issuance of the 
Authorization under section 564(c) of the act were met, on October 23, 
2009, FDA authorized the emergency use of the unapproved drug peramivir 
administered intravenously for treatment of 2009 H1N1 influenza virus 
in certain adult and pediatric patients. The letter of Authorization in 
its entirety (not including the amended authorized version of the Fact 
Sheet for Health Care Providers), as amended on November 19, 2009, 
follows:

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

 Dear Dr. Frieden:

 On October 23, 2009, a letter was issued authorizing the emergency use of the unapproved drug peramivir in response to your request that the Food and Drug Administration (FDA) issue an
 Emergency Use Authorization (EUA) for the emergency use of 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). FDA has received inquiries related to the recommended dosing for
 patients with renal impairment. The purpose of this letter is to amend the Fact Sheet for Health Care Providers to provide additional clarification regarding the dosing recommendations for IV
 peramivir in patients with severe renal impairment, including those who require continuous renal replacement therapy or hemodialysis. The amended authorized version of the Fact Sheet for
 Health Care Providers is enclosed with this letter. In addition, this version of the letter includes minor editorial changes. The letter of authorization, as amended, appears below in its
 entirety:

 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 (HHS) 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 HHS 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

[[Page 20439]]


         (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
         (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 enclosed
 label.

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

        Fact Sheet for Health Care Providers
        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 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 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
