SUMMARY: The Food and Drug Administration (FDA, the Agency, or we) has 
determined that ETHYOL (amifostine) for injection, 500 milligrams (mg)/
vial, was not withdrawn from sale for reasons of safety or 
effectiveness. This determination means that FDA will not begin 
procedures to withdraw approval of abbreviated new drug applications 
(ANDAs) that refer 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: Helen Ryan, Center for Drug Evaluation 
and Research, Food and Drug Administration, 10903 New Hampshire Ave.,

SUPPLEMENTARY INFORMATION: Section 505(j) of the Federal Food, Drug, 
and Cosmetic Act (FD&C Act) (21 U.S.C. 355(j)) allows the submission of 
an ANDA to market a generic version of a previously approved drug 
product. To obtain approval, the ANDA applicant must show, among other 
things, that the generic drug product: (1) has the same active 
ingredient(s), dosage form, route of administration, strength, 
conditions of use, and (with certain exceptions) labeling as the listed 
drug, which is a version of the drug that was previously approved, and 
(2) is bioequivalent to the listed drug. ANDA applicants do not have to 
repeat the extensive clinical testing otherwise necessary to gain 
approval of a new drug application (NDA).
    Section 505(j)(7) of the FD&C Act 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FDA determines that the listed drug was withdrawn from sale for reasons 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determine on its own initiative, whether a listed drug was withdrawn 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may be made at any time after the drug has been withdrawn from sale, 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.
    ETHYOL (amifostine) for injection, 500 mg/vial, is the subject of 
NDA 020221, held by Cosette Pharmaceuticals, Inc., and initially 
approved on December 8, 1995. ETHYOL is a cytoprotective agent 
indicated for reduction of cumulative renal toxicity associated with 
repeated administration of cisplatin in patients with advanced ovarian 
cancer. ETHYOL is also indicated for reduction of the incidence of 
moderate to severe xerostomia in patients undergoing post-operative 
radiation treatment for head and neck cancer, where the radiation port 
includes a substantial portion of the parotid glands.
    ETHYOL (amifostine) for injection, 500 mg/vial, is currently listed 
in the ``Discontinued Drug Product List'' section of the Orange Book.
    Seacross Pharma USA, Inc. submitted a citizen petition dated 
November 5, 2024 (Docket No. FDA-2024-P-5232), under 21 CFR 10.30, 
requesting that the Agency determine whether ETHYOL (amifostine) for 
injection, 500 mg/vial, was 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 ETHYOL (amifostine) for injection, 500 mg/
vial, was not withdrawn for reasons of safety or effectiveness. The 
petitioner has identified no data or other information suggesting that 
this drug product was withdrawn for reasons of safety or effectiveness. 
We have carefully reviewed our files for records concerning the 
withdrawal of ETHYOL (amifostine) for injection, 500 mg/vial, from 
sale. We have also independently evaluated relevant literature and data 
for possible postmarketing adverse events. We have found no information 
that would indicate that this drug product was withdrawn from sale for 
reasons of safety or effectiveness.
    Accordingly, the Agency will continue to list ETHYOL (amifostine) 
for injection, 500 mg/vial, 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 
approved ANDAs that refer to this drug product. Additional ANDAs for 
this drug product 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.
