[Docket No. FDA-2008-P-0278]
Determination That Cysteine Hydrochloride Injection, USP, 7.25%,
Was Not Withdrawn From Sale for Reasons of Safety or Effectiveness
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is announcing its
determination that Cysteine Hydrochloride Injection, USP, 7.25%
(Cysteine HCl), was not withdrawn from sale for reasons of safety or
effectiveness. This determination will allow FDA to approve abbreviated
new drug applications (ANDAs) for Cysteine HCl if all other legal and
regulatory requirements are met.
FOR FURTHER INFORMATION CONTACT: David Joy, Center for Drug Evaluation
and Research, Food and Drug Administration, 10903 New Hampshire Ave.,
Bldg. 51, rm. 6358, Silver Spring, MD 20993-0002, 301-796-3601.
SUPPLEMENTARY INFORMATION: In 1984, Congress enacted the Drug Price
Competition and Patent Term Restoration Act of 1984 (Public Law 98-417)
(the 1984 amendments), which authorized the approval of duplicate
versions of drug products approved under an ANDA procedure. ANDA
applicants must, with certain exceptions, show that the drug for which
they are seeking approval contains the same active ingredient in the
same strength and dosage form as the ``listed drug,'' which is a
version of the drug that was previously approved.
[[Page 31791]]
Sponsors of ANDAs do not have to repeat the extensive clinical testing
otherwise necessary to gain approval of a new drug application (NDA).
The only clinical data required in an ANDA are data to show that the
drug that is the subject of the ANDA is bioequivalent to the listed
drug.
The 1984 amendments include what is now section 505(j)(7) of the
Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(j)(7)), which
requires FDA to publish a list of all approved drugs. FDA publishes
this list as part of the ``Approved Drug Products With Therapeutic
Equivalence Evaluations,'' which is known generally as the ``Orange
Book.'' Under FDA regulations, drugs are removed from the list if the
agency withdraws or suspends approval of the drug's NDA or ANDA for
reasons of safety or effectiveness or if FDA determines that the listed
drug was withdrawn from sale for reasons of safety or effectiveness
(Sec. 314.162 (21 CFR 314.162)). Under Sec. 314.161(a)(1) (21 CFR
314.161(a)(1)), the agency must determine whether a listed drug was
withdrawn from sale for reasons of safety or effectiveness before an
ANDA that refers to that listed drug may be approved. FDA may not
approve an ANDA that does not refer to a listed drug.
Cysteine HCl is the subject of NDA 19-523, most recently held by
Hospira, Inc. (Hospira), and initially approved on October 22, 1986.
Cysteine HCl is indicated for use as an additive to amino acid
solutions to meet the nutritional requirements of newborn infants
requiring total parenteral nutrition (TPN) and of adult and pediatric
patients with severe liver disease who may have impaired enzymatic
processes and require TPN. It can also be added to amino acid solutions
to provide a more complete profile of amino acids for protein
synthesis. Hospira notified FDA in a letter dated May 26, 2005, that it
had not commercially manufactured and marketed Cysteine HCl, and
voluntarily asked that the NDA be withdrawn. The drug product was moved
to the ``Discontinued Drug Product List'' section of the Orange Book,
and FDA withdrew approval of NDA 19-523 effective June 16, 2006 (71 FR
34940). In previous instances (see, e.g., 74 FR 63404, December 3,
2009; 72 FR 9763, March 5, 2007; 61 FR 25497, May 21, 1996), the agency
has determined that, for purposes of Sec. Sec. 314.161 and 314.162,
never marketing an approved drug product is equivalent to withdrawing
the drug from sale. Regulus Pharmaceutical Consulting, Inc., submitted
a citizen petition, dated April 30, 2008 (Docket No. FDA-2008-P-0278),
under 21 CFR 10.30, requesting that the agency determine whether
Cysteine HCl was withdrawn from sale for reasons of safety or
effectiveness.
FDA has reviewed its records and, under Sec. 314.161, has
determined that Cysteine Hydrochloride Injection, USP, 7.25%, was not
withdrawn for reasons of safety or effectiveness. We have also
independently evaluated relevant literature and have found no
information that would indicate that this product was withheld from
sale for reasons of safety or effectiveness. Accordingly, the agency
will continue to list Cysteine Hydrochloride Injection, USP, 7.25%, in
the ``Discontinued Drug Product List'' section of the Orange Book. The
``Discontinued Drug Product List'' delineates, among other items, drug
products that have been discontinued from marketing for reasons other
than safety or effectiveness. ANDAs that refer to Cysteine
Hydrochloride Injection, USP, 7.25% may be approved by the agency if
all other legal and regulatory requirements for the approval of ANDAs
are met. If FDA determines that the labeling for this drug product
should be revised to meet current standards, the agency will advise
ANDA applicants to submit such labeling.
Dated: May 27, 2010.
Leslie Kux,
Acting Assistant Commissioner for Policy.
