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 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.Start Printed Page 69089

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approval of the drug's NDA or ANDA for reasons of safety or effectiveness or if FDA determines that the listed drug was withdrawn from sale for reasons of safety or effectiveness (21 CFR 314.162). Under § 314.161(a)(1) (21 CFR 314.161(a)(1)), the Agency must determine whether a listed drug was withdrawn from sale for reasons of safety or effectiveness before an ANDA that refers to that listed drug may be approved.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.

Amphetamine sulfate, 5 mg and 10 mg tablets, is the subject of ANDA 083901 held by Lannett Company Inc. (Lannett). Amphetamine sulfate is a sympathomimetic amine indicated for treatment of narcolepsy, attention deficit disorder with hyperactivity, and exogenous obesity, as described in the labeling.

In a letter dated April 4, 1994, Lannett notified FDA that Amphetamine sulfate, 5 mg and 10 mg tablets, had been discontinued, and FDA moved the drug product to the “Discontinued Drug Product List” section of the Orange Book.

Lachman Consultant Services submitted a citizen petition dated June 12, 2009 (Docket No. FDA-2009-P-0273), under 21 CFR 10.30, requesting that the Agency determine whether Amphetamine sulfate, 5 mg and 10 mg tablets, was withdrawn from sale for reasons of safety or effectiveness.

After considering the citizen petition and reviewing Agency records, FDA has determined under § 314.161 that Amphetamine sulfate, 5 mg and 10 mg tablets, was not withdrawn for reasons of safety or effectiveness. The petitioner has identified no data or other information suggesting that Amphetamine sulfate, 5 mg and 10 mg tablets, was withdrawn for reasons of safety or effectiveness. We have carefully reviewed our files for records concerning the withdrawal of Amphetamine sulfate, 5 mg and 10 mg tablets, 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 Amphetamine sulfate, 5 mg and 10 mg tablets, 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 Amphetamine sulfate, 5 mg and 10 mg tablets, 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.
