Determination That REYATAZ (Atazanavir Sulfate) Capsules, 100 
Milligrams, Were Not Withdrawn From Sale for Reasons of Safety or 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 or Agency) has 
determined that REYATAZ (atazanavir sulfate) capsules, 100 milligrams 
(mg), were not withdrawn from sale for reasons of safety or 
effectiveness. This determination will allow FDA to approve abbreviated 
new drug applications (ANDAs) for atazanavir sulfate, 100 mg, if all 
other legal and regulatory requirements are met.

FOR FURTHER INFORMATION CONTACT: Na'Im R. Moses, Center for Drug 
Evaluation and Research, Food and Drug Administration, 10903 New 
Hampshire Ave., Bldg. 51, Rm. 6224, Silver Spring, MD 20993-0002, 240-
402-3990.

SUPPLEMENTARY INFORMATION: In 1984, Congress enacted the Drug Price 
Competition and Patent Term Restoration Act of 1984 (Pub. L. 98-417) 
(the 1984 amendments), which authorized the approval of duplicate 
versions of drug products 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 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drug was withdrawn from sale for reasons of safety or effectiveness (21 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).
    A person may petition the Agency to determine, or the Agency may 
determine on its own initiative, whether a listed drug was withdrawn 
from sale for reasons of safety or effectiveness. This determination 
may be made at any time after the drug has been withdrawn from sale, 
but must be made prior to approving an ANDA that refers to the listed 
drug (Sec.  314.161 (21 CFR 314.161)). FDA may not approve an ANDA that 
does not refer to a listed drug.
    REYATAZ (atazanavir sulfate) capsules, 100 mg, is the subject of 
NDA 21-567, held by Bristol-Myers Squibb, and initially approved on 
June 20, 2003.

REYATAZ is a protease inhibitor indicated for use in combination with 
other antiretroviral agents for the treatment of human immunodeficiency 
virus (HIV-1) infection in patients 3 months and older weighing at 
least 10 kilograms.
    In a letter dated August 19, 2014, Bristol-Myers Squibb notified 
FDA that REYATAZ (atazanavir sulfate) capsules, 100 mg, had been 
discontinued. The REYATAZ 150-, 200-, and 300-mg capsule strengths 
continue to be marketed by Bristol-Myers Squibb. The 100-mg dosage 
strength of this drug product is currently listed in the ``Discontinued 
Drug Product List'' section of the Orange Book.
    Lachman Consultant Services, Inc., submitted a citizen petition 
dated July 7, 2014 (Docket No. FDA-2014-P-0980), under 21 CFR 10.30, 
requesting that the Agency determine whether REYATAZ (atazanavir 
sulfate) capsules, 100 mg, were withdrawn from sale for reasons of 
safety or effectiveness.
    After considering the citizen petition and reviewing Agency records 
and based on the information we have at this time, FDA has determined 
under Sec.  314.161 that REYATAZ (atazanavir sulfate) capsules, 100 mg, 
were not withdrawn for reasons of safety or effectiveness. The 
petitioner has identified no data or other information suggesting that 
REYATAZ (atazanavir sulfate) capsules, 100 mg, were withdrawn for 
reasons of safety or effectiveness. We have carefully reviewed our 
files for records concerning the withdrawal of REYATAZ (atazanavir 
sulfate) capsules, 100 mg, from sale. We have also independently 
evaluated relevant literature and data for possible postmarketing 
adverse events. We have reviewed the available evidence and determined 
that the product was not withdrawn from sale for reasons of safety or 
effectiveness.
    Accordingly, the Agency will continue to list REYATAZ (atazanavir 
sulfate) capsules, 100 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. ANDAs that refer to REYATAZ (atazanavir sulfate) 
capsules, 100 mg, may 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: December 30, 2014.

Associate Commissioner for Policy.
