Notice of proposed rulemaking.
This proposed rule is issued by the Deputy Administrator of the Drug Enforcement Administration (DEA) to place the substance lisdexamfetamine, including its salts, isomers, and salts of isomers, into schedule II of the Controlled Substances Act (CSA). This proposed action is based on a recommendation from the Assistant Secretary for Health of the Department of Health and Human Services (DHHS) and on an evaluation of the relevant data by DEA. This scheduling of lisdexamfetamine in schedule II will not be finalized until a New Drug Application (NDA) for a lisdexamfetamine product is approved by the Food and Drug Administration (FDA). If finalized, this action would impose the regulatory controls and criminal sanctions of schedule II on those who handle lisdexamfetamine and products containing lisdexamfetamine.

Lisdexamfetamine is a central nervous system stimulant drug. The Food and Drug Administration (FDA) is currently reviewing a New Drug Application (NDA) for lisdexamfetamine. Upon approval of this pending NDA, lisdexamfetamine will be marketed as a prescription drug product for the treatment of Attention Deficit Hyperactivity Disorder (ADHD).
Lisdexamfetamine is an amide ester conjugate comprised of the amino acid L-lysine covalently bound to the amino group of d-amphetamine. The chemical name of its dimesylate salt form is (2S)-2,6-diamino-N-[(1S)-1-methyl-2-phenethyl]hexanamide dimethanesulfonate (CAS number 608137-32-3). Lisdexamfetamine per se is pharmacologically inactive and its effects are due to its in vivo metabolic conversion to d-amphetamine. In this regard, lisdexamfetamine acts as a prodrug.
Lisdexamfetamine shares substantial pharmacological effects and abuse potential with amphetamine. Lisdexamfetamine is positively reinforcing in monkeys. It generalizes to the discriminative stimulus effects of d-amphetamine in monkeys. It produces locomotor stimulation in rats. In adults, the total amphetamine exposure resulting from 75 mg oral lisdexamfetamine is equivalent to 35 mg oral Adderall XR, an extended release amphetamine product. Peak plasma concentrations of d-amphetamine following oral ingestion of 50 and 70 mg lisdexamfetamine correspond closely to those produced by oral ingestion of 30 and 50 mg immediate-release d-amphetamine product. In controlled clinical studies, lisdexamfetamine has been found to be similar to d-amphetamine in psychoactive measures. It produces euphoria in humans typical of d-amphetamine. Lisdexamfetamine shows an adverse event profile similar to that of d-amphetamine. Some adverse effects of lisdexamfetamine include insomnia, nervousness, irritability, anorexia, weight loss, mood alterations, and increases in blood pressure and heart rate.
Lisdexamfetamine has not been studied for its psychological and physical dependence potential. However, since lisdexamfetamine is a prodrug for d-amphetamine, it is expected to possess dependence potential similar to that of d-amphetamine. d-Amphetamine is known to cause both psychological and physical dependence. Some symptoms of d-amphetamine withdrawal include depression, increase in sleep and food intake, drug craving, anhedonia, irritability and poor concentration.
Lisdexamfetamine is a new molecular entity and has not been marketed in the United States or other countries. Therefore, there has been no evidence of diversion, abuse, or law enforcement encounters involving lisdexamfetamine. On November 14, 2006, the Assistant Secretary for Health, DHHS, sent the Deputy Administrator of DEA a scientific and medical evaluation and a letter recommending that lisdexamfetamine be placed into schedule II of the CSA. Enclosed with the November 14, 2006 letter was a document prepared by the FDA entitled, “Basis for the Recommendation for Control of Lisdexamfetamine in Schedule II of the Controlled Substances Act.” The document contained a review of the factors which the CSA requires the Secretary to consider (21 U.S.C. 811(b)).
The factors considered by the Assistant Secretary of Health and DEA with respect to lisdexamfetamine were:
(1) Its actual or relative potential for abuse;
(2) Scientific evidence of its pharmacological effects;
(3) The state of current scientific knowledge regarding the drug;
(4) Its history and current pattern of abuse;
(5) The scope, duration, and significance of abuse;
(6) What, if any, risk there is to the public health;
(7) Its psychic or physiological dependence liability; and
(8) Whether the substance is an immediate precursor of a substance already controlled under this subchapter. (21 U.S.C. 811(c))
Based on the recommendation of the Assistant Secretary for Health, received in accordance with section 201(b) of the Act (21 U.S.C. 811(b)), and the independent review of the available data by DEA, the Deputy Administrator of DEA, pursuant to sections 201(a) and 201(b) of the Act (21 U.S.C. 811(a) and 811(b)), finds that:
(1) Lisdexamfetamine has a high potential for abuse;
(2) Upon approval of the pending NDA, lisdexamfetamine will have a currently accepted medical use in treatment in the United States; and
(3) Abuse of lisdexamfetamine may lead to severe psychological or physical dependence.
Based on these findings, the Deputy Administrator of DEA concludes that lisdexamfetamine, including its salts, isomers, and salts of isomers, warrants control in schedule II of the CSA, if and when an NDA for lisdexamfetamine is approved.
Interested persons are invited to submit their comments, objections or requests for a hearing with regard to this proposal. Requests for a hearing should state, with particularity, the issues concerning which the person desires to be heard. All correspondence regarding this matter should be submitted to the Deputy Administrator, Drug Enforcement Administration, Washington, DC, 20537, Attention: DEA Federal Register Representative/ODL. In the event that comments, objections, or requests for a hearing raise one or more issues which the Deputy Administrator finds warrant a hearing, the Deputy Administrator shall order a public hearing by notice in the Federal Register, summarizing the issues to be heard and setting the time for the hearing.

Executive Order 12866
In accordance with the provisions of the CSA (21 U.S.C. 811(a)), this action is a formal rulemaking “on the record after opportunity for a hearing.” Such proceedings are conducted pursuant to the provisions of 5 U.S.C. 556 and 557 and, as such, are exempt from review by the Office of Management and Budget pursuant to Executive Order 12866, section 3(d)(1).
Regulatory Flexibility Act
The Deputy Administrator, in accordance with the Regulatory Flexibility Act (5 U.S.C. 605(b)), has reviewed this proposed rule and by approving it certifies that it will not have a significant economic impact on a substantial number of small entities. Lisdexamfetamine products will be prescription drugs used for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). Handlers of lisdexamfetamine will also handle other controlled substances used to treat ADHD which are already subject to the regulatory requirements of the CSA.
This regulation meets the applicable standards set forth in Sections 3(a) and 3(b)(2) of Executive Order 12988 Civil Justice Reform.
This rulemaking does not preempt or modify any provision of state law; nor does it impose enforcement responsibilities on any state; nor does it diminish the power of any state to enforce its own laws. Accordingly, this rulemaking does not have federalism implications warranting the application of Executive Order 13132.
Unfunded Mandates Reform Act of 1995
This rule will not result in the expenditure by state, local and tribal governments, in the aggregate, or by the private sector, of $118,000,000 or more in any one year, and will not significantly or uniquely affect small governments. Therefore, no actions were deemed necessary under provisions of the Unfunded Mandates Reform Act of 1995.
Congressional Review Act
This rule is not a major rule as defined by § 804 of the Small Business Regulatory Enforcement Fairness Act of 1996 (Congressional Review Act). This rule will not result in an annual effect on the economy of $100,000,000 or more; a major increase in costs or prices; or significant adverse effects on competition, employment, investment, productivity, innovation, or on the ability of United States-based companies to compete with foreign based companies in domestic and export markets.Start List of Subjects
