Note Regarding This Scheduling Action
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 the Administrative Procedure Act (5 U.S.C. 556 and 557).
Interested persons are invited to submit their comments, objections or requests for a hearing with regard to this proposal. Requests for a hearing should be made in accordance with 21 CFR 1308.44 and should state, with particularity, the issues concerning which the person desires to be heard. All correspondence regarding this matter should be submitted to the DEA using the address information provided above.
Background
Lacosamide, known chemically as (R)-2-acetoamido-N-benzyl-3- methoxy-propionamide, is a central nervous system depressant drug with a mechanism of action different from those of other central nervous system depressants (e.g, benzodiazepines, barbiturates etc.) that are controlled under the CSA. Unlike other depressant drugs
(benzodiazepines, barbiturates etc.), lacosamide does not act on the gamma amino butyric acid (GABA) system and does not have biologically significant affinity at numerous receptors, channels and transporters that are associated with known drugs of abuse. Although the precise mechanism of action of lacosamide remains undetermined, in vitro studies suggest that it causes selective enhancement of slow inactivation of voltage-gated sodium channels and binds to the collapsing response mediator protein 2 (CRMP-2).
On October 28, 2008, the Food and Drug Administration (FDA) approved lacosamide [(R)-2-acetoamido-N-benzyl-3-methoxy-propionamide] for marketing under the trade name Vimpat[supreg] for use as an adjunctive therapy in treatment of partial-onset seizures in patients with epilepsy aged 17 years and older.
Animal studies have demonstrated that lacosamide protects against seizures in various anticonvulsant models and produces antinociceptive effects in preclinical neuropathic pain models. Animal studies also indicate that
Page 10206
lacosamide has abuse potential. Lacosamide produces dose dependent sedative-type behaviors in rats. In drug discrimination tests, Schedule
IV drugs, alprazolam and phenobarbital, partially generalizes to lacosamide in rats trained to recognize lacosamide.
Clinical studies also indicate that lacosamide has abuse potential.
In a clinical study with recreational abusers of sedative hypnotic drugs, lacosamide, similar to alprazolam, produced subjective responses of ``sedation,'' ``high,'' ``euphoria,'' ``drug liking,'' and ``good drug effects'' similar to alprazolam. These effects of lacosamide were shorter in duration as compared to those of alprazolam. In clinical pharmacokinetic and electrocardiographic studies, healthy subjects reported a high rate of euphoria-type responses following lacosamide administration, suggesting its ability to produce psychological dependence. The data from animal and human studies indicate that chronic administration of lacosamide does not produce physical dependence, as there were no withdrawal symptoms upon its discontinuation.
Adverse events from clinical studies included cognitive disorder, disturbance in attention, mood alteration, depressed mood, irritability, feeling drunk, memory impairment, somnolence, and dizziness. These and other data indicate that public health risks of lacosamide are similar, but in a lower intensity and shorter duration, to those of other sedative hypnotics and central nervous system depressants, such as benzodiazepines.
Lacosamide is a new molecular entity and has not been marketed in the United States. As such, there has been no evidence of diversion, abuse, and law enforcement encounters involving lacosamide.
On December 2, 2008, the Assistant Secretary for Health of the DHHS sent the Administrator of the DEA a scientific and medical evaluation and a letter recommending that lacosamide be placed into Schedule V of the CSA. Enclosed with the December 2, 2008 letter was a document prepared by the FDA entitled, ``Basis for the Recommendation for
Control of Lacosamide in Schedule V of the Controlled Substances Act
(CSA).'' 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 Acting Assistant Secretary of Health and DEA with respect to lacosamide 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 Acting Assistant Secretary for
Health, DHHS, received in accordance with Sec. 201(b) of the Act (21
U.S.C. 811(b)), and the independent review of the available data by the
DEA, the Deputy Administrator of the DEA, pursuant to Sec. Sec. 201(a) and 201(b) of the Act (21 U.S.C. 811(a) and 811(b)), finds that: 1. Lacosamide has a low potential for abuse relative to the drugs or other substances in Schedule IV; 2. Lacosamide has a currently accepted medical use in treatment in the United States; and 3. Abuse of lacosamide may lead to limited physical dependence or psychological dependence relative to the drugs or other substances in
Schedule IV.
Based on these findings, the Deputy Administrator of the DEA concludes that lacosamide and all products containing lacosamide, warrant control in Schedule V of the CSA.
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 DEA using the address information provided above. 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.
Requirements for Handling Lacosamide
If this rule is finalized as proposed, lacosamide and all products containing lacosamide would be subject to the CSA and the Controlled
Substances Import and Export Act (CSIEA) regulatory controls and administrative, civil and criminal sanctions applicable to the manufacture, distribution, dispensing, importing, and exporting of a
Schedule V controlled substance, including the following:
Registration. Any person who manufactures, distributes, dispenses, imports, exports, engages in research or conducts instructional activities with lacosamide, or who desires to manufacture, distribute, dispense, import, export, engage in instructional activities or conduct research with lacosamide, would need to be registered to conduct such activities in accordance with Part 1301 of Title 21 of the Code of
Federal Regulations (CFR).
Security. Lacosamide would be subject to Schedule III-V security requirements and must be manufactured, distributed and stored in accordance with Sec. Sec. 1301.71, 1301.72(b), (c), and (d), 1301.73, 1301.74, 1301.75(b) and (c), 1301.76, and 1301.77 of Title 21 of the
