SUPPLEMENTARY INFORMATION:
Legal Authority
Under the Controlled Substances Act (CSA), each controlled substance is classified into one of five schedules based upon its potential for abuse, its currently accepted medical use in treatment in the United States, and the degree of dependence the drug or other substance may cause. 1 The initial schedules of controlled substances established by Congress are found at 21 U.S.C. 812(c) and the current list of scheduled substances is published at 21 CFR part 1308.
Footnotes:
1 ?21 U.S.C. 812.
Pursuant to 21 U.S.C. 811(a)(2), the Attorney General may, by rule, "remove any drug or other substance from the schedules if he finds that the drug or other substance does not meet the requirements for inclusion in any schedule." The Attorney General has delegated scheduling authority under 21 U.S.C. 811 to the Administrator of the Drug Enforcement Administration (DEA). 2
Footnotes:
2 ?28 CFR 0.100.
The CSA provides that proceedings for the issuance, amendment, or repeal of the scheduling of any drug or other substance may be initiated by the Attorney General on the petition of any interested party. 3 This action was initiated by a petition to remove fenfluramine from the list of scheduled controlled substances of the CSA, and is supported by, inter alia, a recommendation from the Assistant Secretary for Health of the Department of Health and Human Services (HHS) and an evaluation of all relevant data by DEA. This action removes the regulatory controls and administrative, civil, and criminal sanctions applicable to controlled substances, including those specific to schedule IV controlled substances, on persons who handle or propose to handle fenfluramine.

Background
Fenfluramine (chemical name: N -ethyl-a-methyl-3-(trifluoromethyl)phenethylamine), including its salts, isomers, and salts of such isomers, has been controlled under 21 CFR 1308.14(d) as a schedule IV substance of the CSA since June 15, 1973. 4 On September 25, 2019, Zogenix, Inc. (Zogenix; the Sponsor) submitted to the Food and Drug Administration (FDA) a New Drug Application (NDA) for Fintepla (fenfluramine), for the treatment of seizures associated with Dravet syndrome (DS) in patients two years of age and older. FDA approved the NDA on June 25, 2020, with the labelling listing fenfluramine as a schedule IV controlled substance.
Footnotes:
4 ?38 FR 15719, May 9, 1973.
On October 18, 2018, Zogenix submitted to DEA a petition requesting that fenfluramine be removed from schedule IV of the CSA. The petition complied with the requirements of 21 CFR 1308.43(b) and DEA accepted the petition for filing on November 13, 2018.
Notice of Proposed Rulemaking To Decontrol Fenfluramine
On July 19, 2022, DEA published a notice of proposed rulemaking (NPRM) to remove fenfluramine from the schedules of the CSA. 5 The NPRM provided an opportunity for interested persons to file a request for a hearing in accordance with DEA regulations by August 18, 2022. No requests for such a hearing were received by DEA. The NPRM also provided an opportunity for interested persons to submit comments on the proposal on or before August 18, 2022.
Footnotes:
5 ?87 FR 42979.
Comment Received
DEA received one comment on the NPRM to remove fenfluramine from control.
Opposition to rulemaking: One commenter opposed decontrol of fenfluramine, however the comment was at times ambiguous. The commenter seemed to be concerned about children using fenfluramine illicitly and the potential harm related to the combined use with a stimulant, specifically noting the fenfluramine-phentermine ("fen-phen") combination and noting "Stimulants+Psychedelics=Psychosis."
DEA Response: DEA acknowledges the commenter's concerns about relative harm, especially related to children. DEA notes FDA approved Fintepla (fenfluramine) on June 25, 2020, for the treatment of DS in patients two years of age and older. Currently Fintepla is the only FDA-approved drug product with fenfluramine. HHS considered the harms the fenfluramine-phentermine combination produced in their April 2021 scientific and medical evaluation, which was provided to DEA as part of this rulemaking process, pursuant to 21 U.S.C. 811(b).
DEA notes that the combination historically produced serious cardiac effects, not psychological effects. The FDA-approved labeling for Fintepla indicates that patients must be enrolled in the Fintepla risk evaluation and mitigation strategy (REMS) program and undergo cardiac monitoring before, during, and after treatment with Fintepla to monitor for serious heart valve changes or high blood pressure in the arteries of the lungs. The FDA-required REMS program for Fintepla, including ongoing cardiac monitoring, would still be applicable under the FDA rules even after fenfluramine is decontrolled by DEA.
Based on FDA's scientific and medical review of the eight factors and findings related to the substance's abuse potential, legitimate medical use, and dependence liability, HHS recommended that fenfluramine and its salts be removed from all schedules of the CSA. Pursuant to 21 U.S.C. 811(b), the recommendations of HHS shall be binding on DEA as to such scientific and medical matters and if the Secretary recommends that a drug or other substance not be controlled, DEA shall not control the drug or other substances. As stated in the NPRM, after careful review of all relevant data including HHS' scientific and medical evaluation and scheduling recommendation, DEA is therefore promulgating this final rule to remove fenfluramine, including its salts, isomers, and salts of such isomers whenever the existence of such salts, isomers, and salts of isomers is possible, from control under the CSA.
Determination To Decontrol Fenfluramine
[top] Based on consideration of the comment, and the rationale set forth in the NPRM, the Administrator finds that fenfluramine does not meet the requirements for inclusion in any schedule. As such, DEA is removing fenfluramine, including its salts, isomers, and salts of such isomers whenever the existence of such salts, isomers, and salts of isomers is possible, from control under the CSA.
Regulatory Analyses
Executive Orders 12866 (Regulatory Planning and Review) and 13563 (Improving Regulation and Regulatory Review)
In accordance with 21 U.S.C. 811(a), this scheduling action is subject to formal rulemaking procedures done "on the record after opportunity for a hearing," which are conducted pursuant to the provisions of 5 U.S.C. 556 and 557. The CSA sets forth the criteria for removing a drug or other substance from the list of controlled substances. Such actions are exempt from review by the Office of Management and Budget pursuant to section 3(d)(1) of Executive Order (E.O.) 12866 and the principles reaffirmed in E.O. 13563.
Executive Order 12988, Civil Justice Reform
This regulation meets the applicable standards set forth in sections 3(a) and 3(b)(2) of E.O. 12988 to eliminate drafting errors and ambiguity, minimize litigation, provide a clear legal standard for affected conduct, and promote simplification and burden reduction.
Executive Order 13132, Federalism
This rulemaking does not have federalism implications warranting the application of E.O. 13132. This rule does not have substantial direct effects on the States, on the relationship between the Federal government and the States, or the distribution of power and responsibilities among the various levels of government.
Executive Order 13175, Consultation and Coordination With Indian Tribal Governments
This rule does not have tribal implications warranting the application of E.O. 13175. This rule does not have substantial direct effects on one or more Indian tribes, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes.
Regulatory Flexibility Act
The Administrator, in accordance with the Regulatory Flexibility Act (5 U.S.C. 601-612), has reviewed this rule and by approving it certifies that it will not have a significant economic impact on a substantial number of small entities. The purpose of this rule is to remove fenfluramine from the list of schedules of the CSA. This action will remove regulatory controls and administrative, civil, and criminal sanctions applicable to controlled substances for handlers and proposed handlers of fenfluramine. Accordingly, it has the potential for some economic impact in the form of cost savings.
Fenfluramine as a pharmaceutical product (Fintepla) is currently available and marketed in the U.S. Because fenfluramine is currently a schedule IV drug, all legal handling of fenfluramine is currently done under appropriate DEA license. In such instances, DEA's knowledge of its registrant population forms the basis for estimating the number of affected entities and small entities that are affected by this rulemaking. There are currently 40 unique registrations authorized to handle fenfluramine specifically, as well as a number of registered analytical labs that are authorized to handle schedule IV controlled substances generally. From review of entity names, DEA estimates these 40 registrations represent 27 entities. Some of these entities are likely to be small entities. However, since DEA does not have information of registrant size and the majority of DEA registrants are small entities or are employed by small entities, DEA estimates a maximum of 27 entities are small entities. Therefore, DEA conservatively estimates as many as 27 small entities are affected by this final rule. However, because this rule would remove fenfluramine from regulatory controls of the CSA, it is likely to result in some cost savings. Any person planning to handle fenfluramine will realize cost savings in the form of saved DEA registration fees, and the elimination of physical security, recordkeeping, and reporting requirements. Because of these factors, DEA projects that this rule will not result in a significant economic impact on a substantial number of small entities.
Administrative Procedure Act
The Administrative Procedure Act requires the publication of a substantive rule to be made not less than 30 days before its effective date. 6 However, this requirement need not apply for "a substantive rule which . . . relieves a restriction."? 7 Therefore, DEA makes this rule effective immediately upon publication.

Unfunded Mandates Reform Act of 1995
In accordance with the Unfunded Mandates Reform Act (UMRA) of 1995, 2 U.S.C. 1501 et seq., DEA has determined that this action would not result in any Federal mandate that may result "in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100,000,000 or more (adjusted annually for inflation) in any 1 year." Therefore, neither a Small Government Agency Plan nor any other action is required under UMRA of 1995.
Congressional Review Act
This rule is not a major rule as defined by the Congressional Review Act (CRA), 5 U.S.C. 804. However, pursuant to the CRA, DEA is submitting a copy of the final rule to both Houses of Congress and to the Comptroller General.
