Nov 02, 2009 (FIND, Inc. via COMTEX) --
BCRX | Quote | Chart | News | PowerRating -- 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.

ADDRESSES: Submit written requests for single copies of the Emergency Use Authorization(s) to the Office of Counterterrorism and Emerging Threats (HF- 29), Food and Drug Administration, 5600 Fishers Lane, 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.

SUPPLEMENTARY INFORMATION: 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.[END FOOTNOTE]

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.

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. S. 360bbb-3).
On April 26, 2009, pursuant to section 564(b)(1)(C) of the Act (21 U.S.C. S.
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.
S. 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. S. 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. S. 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
(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 [degrees]
C-30 [degrees] C or 59 [degrees] F-86 [degrees] 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
