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approval of the drug's NDA or ANDA for reasons of safety or effectiveness or if FDA determines that the listed drug was withdrawn from sale for reasons of safety or effectiveness (21 CFR 314.162).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may petition the Agency to determine, or the Agency may determine on its own initiative, whether a listed drug was withdrawn from sale for reasons of safety or effectiveness. This determination may be made at any time after the drug has been withdrawn from sale, but must be made prior to approving an ANDA that refers to the listed drug (§ 314.161 (21 CFR 314.161)). FDA may not approve an ANDA that does not refer to a listed drug.

KYTRIL (granisetron hydrochloride) tablets, EQ 1 mg and 2 mg base, are the subject of NDA 020305, held by Hoffmann-La Roche, Inc., and initially approved on March 16, 1995. KYTRIL is indicated for the prevention of nausea and/or vomiting associated with initial and repeat courses of emetogenic cancer therapy, including high-dose cisplatin, and for the prevention and treatment of postoperative nausea and vomiting in adults.

On April 30, 2012, Hoffman-La Roche notified FDA that KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, were being discontinued, and FDA moved the drug products to the “Discontinued Drug Product List” section of the Orange Book.

Kurt R. Karst, on behalf of Hyman, Phelps & McNamara, P.C., submitted a citizen petition dated May 27, 2015 (Docket No. FDA-2015-P-1898), under 21 CFR 10.30, requesting that the Agency determine whether KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, 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 § 314.161 that KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, were not withdrawn for reasons of safety or effectiveness. The petitioner has identified no data or other information suggesting that KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, were withdrawn for reasons of safety or effectiveness We have carefully reviewed our files for records concerning the withdrawal of KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, 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 products were not withdrawn from sale for reasons of safety or effectiveness.

Accordingly, the Agency will continue to list KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, 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 KYTRIL (granisteron hydrochloride) tablets, EQ 1 mg and 2 mg base, 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.
