SUPPLEMENTARY INFORMATION: jspears on DSK121TN23PROD with PROPOSALS1 I. Background and Purpose of Hearing Under the Delaney Clause (section 512(d)(1)(I) (21 U.S.C. 360b(d)(1)(I)) of the Federal Food, Drug, and Cosmetic Act (FD&C Act)), FDA generally cannot approve a new animal drug application (NADA) if the drug that is the subject of that application induces cancer in humans or animals. An exception to this general rule is commonly known as the Diethylstilbestrol ‘‘DES’’ Proviso, which allows for the approval of a carcinogenic VerDate Sep<11>2014 17:38 Jan 12, 2022 Jkt 256001 new animal drug where FDA finds that under the approved conditions of use: (1) The drug will not adversely affect the animals treated with the drug and (2) no residues of the drug will be found by an approved regulatory method in any edible tissues of, or in any foods yielded by, the animal (section 512(d)(1)(I) of the FD&C Act). On July 20, 2020, the Agency published a notice in the Federal Register proposing an order to revoke the approved method for detecting residues of carbadox, a carcinogenic new animal drug used in swine feed. (85 FR 43853, July 20, 2020; Docket No. FDA–2020–N–0955, ‘‘Phibro Animal Health Corp.; Carbadox in Medicated Swine Feed; Revocation of Approved Method.’’) The currently approved method measures quinoxaline-2carboxylic acid (QCA) as a marker residue to detect the presence of the residue of carcinogenic concern. (Determination of Carbadox (as Quinoxaline-2-Carboxylic [QCA]) Residues in Swine Liver and Muscle Tissues After Drug Withdrawal, https:// www.fda.gov/about-fda/centerveterinary-medicine/cvm-foia-electronic -reading-room.) The proposal to revoke the approved method for carbadox is based on CVM’s determination that the method is inadequate to monitor residue of carcinogenic concern in compliance with FDA’s regulations in part 500, subpart E (21 CFR part 500, subpart E). These regulations set out the requirements for demonstrating that no residues of the drug will be found by an approved regulatory method in any edible tissues of or in any foods obtained from the animal, as required to meet the requirements of the DES Proviso. The purpose of the public hearing is to gather additional data and information related to the residue of carcinogenic concern for the new animal drug carbadox. II. Notice of Hearing Under 21 CFR Part 15 This public hearing will be held in accordance with part 15 (21 CFR part 15). Pursuant to § 15.1(a) and authority delegated from the Commissioner of Food and Drugs as referenced in the FDA Staff Manual Guide 1410.21(1)(B)(6) and (1)(D), the FDA Acting Chief Scientist concludes, as a matter of discretion, that it is in the public interest to permit persons to present information and views at a public hearing on this matter. The hearing will be conducted by a presiding officer, who will be PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 accompanied by other United States Government employees serving as a panel in conducting the hearing. Under § 15.30(f), the hearing is informal, and the rules of evidence do not apply. Only the presiding officer and panel members can pose questions; they can question any person during or at the conclusion of each presentation. To the extent that the conditions for the hearing, as described in this notice, conflict with any provisions set out in part 15, this notice acts as a waiver of those provisions as specified in § 15.30(h). III. Topics for the Public Hearing We encourage public comments and presentations at the public hearing. We are particularly interested in receiving comments, data, and information about the topics listed below. In submitting comments, data, and information to the docket, please identify available references for the data and information, as well as the specific item number listed below, if applicable. Please reference, but do not resubmit, any information already contained in Docket No. FDA–2020–N–0955, ‘‘Phibro Animal Health Corp.; Carbadox in Medicated Swine Feed; Revocation of Approved Method.’’ 1. Data to inform our knowledge of the residue of carcinogenic concern not summarized in the Freedom of Information summary for the 1998 supplemental approvals, including additional data regarding the fraction of noncarcinogenic residues in the total radiolabeled residues of carbadox. 2. For any given concentration of a marker residue, the corresponding concentration of the residue of carcinogenic concern. 3. Additional information not already contained in Docket No. FDA–2020–N– 0955, ‘‘Phibro Animal Health Corp.; Carbadox in Medicated Swine Feed; Revocation of Approved Method’’ related to the adequacy of the current approved method to measure QCA as a marker residue for the residue of carcinogenic concern for the new animal drug carbadox. 4. Any method, other than the current approved method, that demonstrates ‘‘no residue’’ for the new animal drug carbadox in conformance with part 500, Subpart E. 5. Detailed information on the conduct and quality of studies providing data to support the points above, including information on the extraction process and the stability of residues being analyzed.

SUPPLEMENTARY INFORMATION:

I. Background and Purpose of Hearing

    Under the Delaney Clause (section 512(d)(1)(I) (21 U.S.C. 
360b(d)(1)(I)) of the Federal Food, Drug, and Cosmetic Act (FD&C Act)), 
FDA generally cannot approve a new animal drug application (NADA) if 
the drug that is the subject of that application induces cancer in 
humans or animals. An exception to this general rule is commonly known 
as the Diethylstilbestrol ``DES'' Proviso, which allows for the 
approval of a carcinogenic new animal drug where FDA finds that under 
the approved conditions of use: (1) The drug will not adversely affect 
the animals treated with the drug and (2) no residues of the drug will 
be found by an approved regulatory method in any edible tissues of, or 
in any foods yielded by, the animal (section 512(d)(1)(I) of the FD&C 
Act).
    On July 20, 2020, the Agency published a notice in the Federal 
Register proposing an order to revoke the approved method for detecting 
residues of carbadox, a carcinogenic new animal drug used in swine 
feed. (85 FR 43853, July 20, 2020; Docket No. FDA-2020-N-0955, ``Phibro 
Animal Health Corp.; Carbadox in Medicated Swine Feed; Revocation of 
Approved Method.'') The currently approved method measures quinoxaline-
2-carboxylic acid (QCA) as a marker residue to detect the presence of 
the residue of carcinogenic concern. (Determination of Carbadox (as 
Quinoxaline-2-Carboxylic [QCA]) Residues in Swine Liver and Muscle 
Tissues After Drug Withdrawal, https://www.fda.gov/about-fda/center-veterinary-medicine/cvm-foia-electronic-reading-room.) The proposal to 
revoke the approved method for carbadox is based on CVM's determination 
that the method is inadequate to monitor residue of carcinogenic 
concern in compliance with FDA's regulations in part 500, subpart E (21 
CFR part 500, subpart E). These regulations set out the requirements 
for demonstrating that no residues of the drug will be found by an 
approved regulatory method in any edible tissues of or in any foods 
obtained from the animal, as required to meet the requirements of the 
DES Proviso. The purpose of the public hearing is to gather additional 
data and information related to the residue of carcinogenic concern for 
the new animal drug carbadox.

II. Notice of Hearing Under 21 CFR Part 15

    This public hearing will be held in accordance with part 15 (21 CFR 
part 15). Pursuant to Sec.  15.1(a) and authority delegated from the 
Commissioner of Food and Drugs as referenced in the FDA Staff Manual 
Guide 1410.21(1)(B)(6) and (1)(D), the FDA Acting Chief Scientist 
concludes, as a matter of discretion, that it is in the public interest 
to permit persons to present information and views at a public hearing 
on this matter. The hearing will be conducted by a presiding officer, 
who will be accompanied by other United States Government employees 
serving as a panel in conducting the hearing. Under Sec.  15.30(f), the 
hearing is informal, and the rules of evidence do not apply. Only the 
presiding officer and panel members can pose questions; they can 
question any person during or at the conclusion of each presentation. 
To the extent that the conditions for the hearing, as described in this 
notice, conflict with any provisions set out in part 15, this notice 
acts as a waiver of those provisions as specified in Sec.  15.30(h).

III. Topics for the Public Hearing

    We encourage public comments and presentations at the public 
hearing. We are particularly interested in receiving comments, data, 
and information about the topics listed below. In submitting comments, 
data, and information to the docket, please identify available
