[Docket No. FDA-2010-P-0157]
Determination That VESANOID (Tretinoin) Capsules, 10 Milligrams,
Were Not Withdrawn From Sale for Reasons of Safety or Effectiveness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) has determined that
VESANOID (tretinoin) Capsules, 10 milligrams (mg), were not withdrawn
from sale for reasons of safety or effectiveness. This determination
means that FDA will not begin procedures to withdraw approval of the
abbreviated new drug application (ANDA) that refers to this drug
product, and it will allow FDA to continue to approve ANDAs that refer
to the product as long as they meet relevant legal and regulatory
requirements.
FOR FURTHER INFORMATION CONTACT: Molly Flannery, Center for Drug
Evaluation and Research, Food and Drug Administration, 10903 New
Hampshire Ave., Bldg. 51, rm. 6237, Silver Spring, MD 20993-0002, 301-
796-3543.
SUPPLEMENTARY INFORMATION: In 1984, Congress enacted the Drug Price
Competition and Patent Term Restoration Act of 1984 (Public Law 98-
[[Page 55797]]
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. ANDA applicants 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drug was withdrawn from sale for reasons of safety or effectiveness (21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.
VESANOID (tretinoin) Capsules, 10 mg, are the subject of NDA 20-
438, held by Hoffman-La Roche Inc. (Roche), and initially approved on
November 22, 1995. VESANOID is indicated for the ``induction of
remission in patients with acute promyelocytic leukemia (APL), French-
American-British (FAB) classification M3 (including the M3 variant),
characterized by the presence of the t(15;17) translocation and/or the
presence of the PML/RAR[agr] [promyelocytic leukemia/retinoic acid
receptor alpha] gene who are refractory to, or who have relapsed from,
anthracycline chemotherapy, or for whom anthracycline-based
chemotherapy is contraindicated'' (VESANOID labeling).
In a letter dated December 2, 2009, Roche notified FDA that
VESANOID (tretinoin) Capsules, 10 mg, were being discontinued, and FDA
moved the drug product to the ``Discontinued Drug Product List''
section of the Orange Book. There is one approved ANDA for tretinoin
capsules, 10 mg (ANDA No. 77-684); this drug product is listed in the
Orange Book and, following the discontinuation of VESANOID, was
designated as the reference listed drug to which new ANDAs should
refer.
Rakoczy Molino Mazzochi Siwik LLP submitted a citizen petition
dated March 17, 2010 (Docket No. FDA-2010-P-0157), under 21 CFR 10.30,
requesting that the agency determine whether VESANOID (tretinoin)
Capsules, 10 mg, were withdrawn from sale for reasons of safety or
effectiveness.
After considering the citizen petition and reviewing agency
records, FDA has determined under Sec. 314.161 that VESANOID
(tretinoin) Capsules, 10 mg, were not withdrawn for reasons of safety
or effectiveness. The petitioner has identified no data or other
information suggesting that VESANOID (tretinoin) Capsules, 10 mg, were
withdrawn for reasons of safety or effectiveness. We have carefully
reviewed our files for records concerning the withdrawal of VESANOID
(tretinoin) Capsules, 10 mg, from sale. We have also independently
evaluated relevant literature and data for possible postmarketing
adverse events and have found no information that would indicate that
this product was withdrawn from sale for reasons of safety or
effectiveness.
Accordingly, the agency will continue to list VESANOID (tretinoin)
Capsules, 10 mg, 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. FDA will not
begin procedures to withdraw approval of the approved ANDA that refers
to VESANOID. Additional ANDAs for tretinoin capsules, 10 mg, may also
be approved by the agency as long as they meet all other legal and
regulatory requirements for the approval of ANDAs. If FDA determines
that labeling for this drug product should be revised to meet current
standards, the agency will advise ANDA applicants to submit such
labeling.
Dated: September 8, 2010.
