Start Preamble

AGENCY:

Drug Enforcement Administration, Department of Justice.

ACTION:

Notice of proposed rulemaking.

SUMMARY:

The Drug Enforcement Administration proposes to remove [123 I]ioflupane from the schedules of the Controlled Substances Act. This action is pursuant to the Controlled Substances Act which requires that such actions be made on the record after an opportunity for a hearing through formal rulemaking. [123 I]Ioflupane is, by definition, a schedule II controlled substance because it is derived from cocaine via ecgonine, both of which are schedule II controlled substances. This action would remove the regulatory controls and administrative, civil, and criminal sanctions applicable to controlled substances, including those specific to schedule II controlled substances, on persons who handle (manufacture, distribute, reverse distribute, dispense, conduct research, import, export, or conduct chemical analysis) or propose to handle [123 I]ioflupane.

DATES:

Interested persons may file written comments on this proposal in accordance with 21 CFR 1308.43(g). Electronic comments must be submitted, and written comments must be postmarked, on or before July 6, 2015.

Request for Hearing, Notice of Appearance at or Waiver of Participation in Hearing

Pursuant to 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 (APA) (5 U.S.C. 551-559). 21 CFR 1308.41-1308.45, and 21 CFR part 1316 subpart D. In accordance with 21 CFR 1308.44 (a)-(c), requests for hearing, notices of appearance, and waivers of an opportunity for a hearing or to participate in a hearing may be submitted only by interested persons, defined as those “adversely affected or aggrieved by any rule or proposed rule issuable pursuant to section 201 of the Act (21 U.S.C. 811).” 21 CFR 1300.01. Such requests or notices must conform to the requirements of 21 CFR 1308.44 (a) or (b), and 1316.47 or 1316.48, as applicable, and include a statement of the interest of the person in the proceeding and the objections or issues, if any, concerning which the person desires to be heard. Any waiver must conform to the requirements of 21 CFR 1308.44(c) and 1316.49, including a written statement regarding the interested person's position on the matters of fact and law involved in any hearing.

Legal Authority

The Drug Enforcement Administration (DEA) implements and enforces titles II and III of the Comprehensive Drug Abuse Prevention and Control Act of 1970, as amended. 21 U.S.C. 801-971. Titles II and III are referred to as the “Controlled Substances Act” and the “Controlled Substances Import and Export Act,” respectively, but they are collectively referred to as the “Controlled Substances Act” or the “CSA” for the purposes of this action. The DEA publishes the implementing regulations for these statutes in title 21 of the Code of Federal Regulations (CFR), chapter II. The CSA and its implementing regulations are designed to prevent, detect, and eliminate the diversion of controlled substances and listed chemicals into the illicit market while ensuring an adequate supply is available for the legitimate medical, scientific, research, and industrial needs of the United States. Controlled substances have the potential for abuse and dependence and are controlled to protect the public health and safety.

Under the 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. 21 U.S.C. 812. 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.

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 [or she] 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 DEA, 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 (1) on his or her own motion, (2) at the request of the Secretary of the Department of Health and Human Services,[1] or (3) on the petition of any interested party. 21 U.S.C. 811(a). This action was initiated at the request of the Assistant Secretary for Health of the HHS, and is supported by an evaluation of all relevant data by the HHS and the DEA. This action would remove the regulatory controls and administrative, civil, and criminal sanctions applicable to controlled substances, including those specific to schedule II controlled substances, on persons who handle or propose to handle [123 I]ioflupane.

Background

DaTscan is a single-dose, injectable diagnostic radiopharmaceutical for use in hospital settings with specialized gamma cameras. It was developed as a diagnostic tool for visualization of dopamine transporters (DAT) by using single photon emission computed tomography (SPECT) brain imaging. The Food and Drug Administration (FDA) approved the New Drug Application (NDA) for DaTscan on January 14, 2011, for the indication of visualizing striatal DATs in the brains of adult patients with suspected Parkinsonian syndromes (PS). [123 I]Ioflupane is the active pharmaceutical ingredient (API) in DaTscan and it is a new molecular entity. However, [123 I]Ioflupane is, by definition, a schedule II controlled substance because it is derived from cocaine, a schedule II substance, via ecgonine (a schedule II substance). See 21 U.S.C. 812(c), Schedule II, (a)(4). Start Printed Page 31523Each vial of DaTscan contains 0.325 micrograms (μg) of [123 I]ioflupane per 2.5 milliliters (ml). The average and maximum amounts of non-radioactive ioflupane in each DaTscan vial are estimated to be between 0.21 μg and 0.31 μg. Although ioflupane, the non-radiolabeled API of the drug product DaTscan, binds to DAT and elicits behavioral effects similar to that of cocaine, based upon the available information and DaTscan's unique formulation-specific properties, DaTscan itself presents no practical possibility of abuse, misuse, diversion or clandestine production.

Proposed Determination To Decontrol [123 I]Ioflupane

Pursuant to 21 U.S.C. 811(b), (c), and (f), the HHS recommended to the DEA on November 2, 2010, that FDA-approved products containing [123 I]ioflupane be removed from schedule II of the CSA. HHS provided to DEA a scientific and medical evaluation document entitled “Basis for the Recommendation to Remove FDA Approved Products Containing [123 I]Ioflupane from Schedule II of the Controlled Substances Act (CSA).” Pursuant to 21 U.S.C. 811(b), this document contained an eight-factor analysis of FDA-approved products containing [123 I]ioflupane, along with the HHS's recommendation to remove FDA-approved products containing [123 I]ioflupane from the schedules of the CSA.

In response, the DEA reviewed the scientific and medical evaluation and scheduling recommendation provided by the HHS, and all other relevant data. The DEA and HHS collaborated further regarding the available information. By letter dated February 2, 2015, the HHS provided detailed responses to specific inquiries from the DEA (submitted by letter dated September 16, 2014). Upon further review of all of the available information, the DEA completed its own eight-factor review document on FDA-approved diagnostic products containing [123 I]ioflupane (currently, only DaTscan) pursuant to 21 U.S.C. 811(c). The FDA-approved diagnostic product, DaTscan, was used as the basis for the scientific and medical evaluation of FDA-approved diagnostic products containing [123 I]ioflupane for both the HHS and DEA eight-factor analysis. Included below is a brief summary of each factor as analyzed by the HHS and the DEA, and as considered by the DEA in this proposed rule to remove [123 I]ioflupane from the schedules of the CSA. Please note that both the DEA and HHS analyses and other relevant documents are available in their entirety under “Supporting and Related Material” of the public docket for this rule at http://www.regulations.gov under docket number DEA-415.

1. The Drug's Actual or Relative Potential for Abuse

According to HHS and the DEA, there are no data demonstrating that individuals are administering quantities of DaTscan sufficient to create a hazard to their health or to the safety of other individuals or to the community. In clinical studies, DaTscan, due to its low concentrations of [123 I]ioflupane lacked, central nervous activity (CNS) in humans.

According to HHS review of Sponsor's calculation regarding psychoactive doses of DaTscan, approximately 6,000 vials of DaTscan would be required to produce a subjective “high” in humans from exposure to [123 I]ioflupane in this product. The volume of 6,000 vials is about 15 liters (L) of fluid, an amount that would be lethal if administered intravenously (i.v.). The short half-life of DaTscan (due to its radioactive decay) will prevent its extended storage for future use at the manufacturing, distributing, or radiopharmacy site; thereby limiting the amount available for diversion. It is highly unlikely that individuals will administer DaTscan on their own initiative since DaTscan has a very dilute and small dose of [123 I]ioflupane, and possesses radioactivity. As a result, DaTscan will not have significant capability of creating hazards to the health of the user or to the safety of the community.

2. Scientific Evidence of the Drug's Pharmacological Effects, If Known

DaTscan blocks monoamine transporters, such as DAT and other monoamine transporters such as serotonin transporters. Ioflupane, the active pharmaceutical ingredient in DaTscan, was demonstrated to have an affinity to DAT that was approximately 10- and 100-fold greater than cocaine in rodent brain homogenates or in cells transfected with rat DAT (Neumeyer et al., 1996; Okada et al., 1998; Scheffel et al., 1997). As reported by HHS, non-radiolabeled ioflupane at doses >0.1 mg/kg, i.v. was able to substitute for cocaine in cocaine-trained rats (10 mg/kg, intraperitoneal administration) using a drug discrimination protocol which is predictive of subjective behavioral effects in humans.

HHS reviewed data from eight human clinical trials involving 942 subjects and nine years of post-approval use in Europe and found that there was not any clinical evidence of pharmacological effects resulting from DaTscan administration. The maximum dose of [123 I]ioflupane in DaTscan that is administered to the patient prior to undergoing an imaging procedure is 0.325 μg (0.13 μg/ml). HHS extrapolated from the locomotor study and drug discrimination study on non-radiolabeled ioflupane and estimated that the lowest active dose of DaTscan for a 60 kg (132.2 lb) human to achieve a pharmacologic effect would be 288 μg or 886 vials of DaTscan. In addition, the recreational dose of DaTscan is estimated as 1921 µg or 5,910 vials.

Although [123 I]ioflupane would be expected to have a pharmacological profile nearly identical to its non-radioactive form, its unique properties (i.e., manufacturing limits and radioactive properties) pose practical barriers to its abuse. Furthermore, according to HHS, the amount of [123 I]ioflupane in DaTscan is significantly less than the amounts of ioflupane used to elicit the pharmacological response in preclinical studies with this compound.

3. The State of Current Scientific Knowledge Regarding the Drug or Other Substance

The international non-proprietary name of [123 I]ioflupane is methyl(1R, 2S, 3S, 5S)-8-(3-fluoropropyl)-3-(4-[123 I]iodophenyl)-8-azabicyclo[3,2,1] octane-2-carboxylate. The molecular formula of [123 I]ioflupane is C18 H23 F[123 I]NO2 and the molecular weight is 427.28 g/mol. [123 I]Ioflupane is a clear, colorless solution and is only present in a solution of ethanol and sodium acetate buffer. Non-radioactive ioflupane is a white solid with a melting point of 83 °C to 87 °C and soluble in water (less than 0.1 mg/ml), sodium acetate buffer (pH 7.4; 16 mg/ml), and ethanol (27 mg/ml).

HHS states that meaningful extraction of [123 I]ioflupane from DaTscan would be impossible due to its limited production and availability and because extraction is technically complex and would require advanced equipment not available to the general public. Importantly, if extraction of ioflupane from [123 I]ioflupane is accomplished, the ioflupane would be subject to schedule II controls under the CSA. According to HHS, the retrosynthesis of DaTscan to cocaine and ecgonine would be difficult. Production of DaTscan is technically complex as it requires specialized equipment, facilities, scientific training and expertise, making clandestine manufacturing particularly difficult. HHS indicated that the non-radiolabeled precursors needed for the synthesis of [123 I]ioflupane (and Start Printed Page 31524DaTscan) are abusable. In addition, the non-radiolabeled precursors derived from cocaine or ecgonine are also schedule II controlled substances. However, even if an individual obtained the precursors, it is impractical and highly unlikely that they would synthesize the abusable compound into a radiolabeled formulation with a limited storage life that is not desired by drug users.

On January 14, 2011, FDA approved the NDA for DaTscan with the indication of visualizing striatal dopamine transporters in the brains of adult patients with suspected Parkinsonian syndromes using SPECT imaging. As such, any FDA-approved diagnostic product containing [123 I]ioflupane has a currently accepted medical use in the United States.

4. Its History and Current Pattern of Abuse

According to HHS, there have been no reports of abuse of [123 I]ioflupane. Over 168,000 doses of DaTscan have been administered to patients worldwide, and no pharmacological effects have been noted. Further, according to HHS, no single user has received more than 10 vials of DaTscan in a single day.

5. The Scope, Duration, and Significance of Abuse

There have been no reports of abuse of [[123] I]ioflupane. According to the National Forensic Laboratory Information System (NFLIS) [2] and the System to Retrieve Information from Drug Evidence (STRIDE) [3] , there have been no reports of [123 I]ioflupane seizures during the time period January 2010 to February 2015.

6. What, If Any, Risk There Is to the Public Health

According to the HHS, because of the limited amounts of manufactured DaTscan, the low concentration of [[123] I]ioflupane per vial, and the existence of stringent regulatory controls (controls other than those imposed by the CSA and its implementing regulations, including regulation by the United States Nuclear Regulatory Commission under 10 CFR part 35 and/or by states) [4] on the manufacturing and handling of DaTscan, abuse of DaTscan is not possible as a practical matter. Thus, there is little to no practical risk to public health from DaTscan abuse.

7. Its Psychic or Physiological Dependence Liability

As reviewed by HHS, non-radiolabeled ioflupane has cocaine-like properties. In a drug discrimination study in cocaine-trained rats, non-radiolabeled ioflupane produced cocaine-appropriate responding, which suggests that non-radiolabeled ioflupane may produce cocaine-like subjective effects in humans (HHS, 2010).

However, the available evidence suggests that there is no psychic or physiological dependence potential of FDA-approved diagnostic products containing [123 I]ioflupane. The psychic or physiological dependence potential of FDA-approved diagnostic products is currently expected to be very limited due to the low exposure concentration of [123 I]ioflupane, the aforementioned low potential for abuse (see Factor 1) and the extremely high and lethal quantities needed to achieve a subjective “high.”

8. Whether the Substance Is an Immediate Precursor of a Substance Already Controlled Under the CSA

[123 I]Ioflupane is not an immediate precursor of a substance already controlled under the CSA.

Conclusion

Based on consideration of the scientific and medical evaluation and accompanying recommendation of the HHS and based on the DEA's consideration of its own eight-factor analysis, the DEA finds that the facts and all available and relevant data demonstrate that [123 I]ioflupane does not possess abuse or dependence potential. Accordingly, the DEA finds that [123 I]ioflupane does not meet the requirements for inclusion in any schedule and should be removed from control under the CSA.

Findings for Schedule Placement Pursuant to 21 U.S.C. 812(b)

The CSA outlines the findings required to place a drug or other substance in any particular schedule (I, II, III, IV, or V). 21 U.S.C. 812(b). The Assistant Secretary for Health of the HHS recommended removal of “FDA approved products containing [123 I]ioflupane from schedule II of the” CSA. However, because the DEA finds no basis to remove only FDA approved products containing [123 I]ioflupane from the schedules, this action proposes to remove the substance [123 I]ioflupane from the CSA schedules. Historically, when new molecular entities are removed from control, the substance itself is removed from control rather than the specific FDA-approved drug product (e.g., naloxegol, 80 FR 3468; naloxone, 39 FR 44392). As summarized above, the data currently support removal of substances that contain [123 I]ioflupane, primarily because [123 I]ioflupane itself has a lethal radioactive barrier, and its manufacturing process is highly regulated and technically complex, thus making abuse highly unlikely.

After consideration of the analyses and recommendation of the Assistant Secretary for Health of the HHS and review of all relevant and available data, the Administrator of the DEA, pursuant to 21 U.S.C. 812(b)(5), finds that:

(1) [123 I]Ioflupane has no comparable potential for abuse relative to substances in Schedule V.

(2) [123 I]Ioflupane has a currently accepted medical use in treatment in the United States. FDA approved the New Drug Application for DaTscan on January 14, 2011, with the indication of visualizing striatal dopamine transporters in the brains of adult patients with suspected Parkinsonian syndromes using SPECT imaging.

(3) [123 I]Ioflupane is not abusable, therefore, its use is not likely to lead to physical or psychological dependence.

Based on these findings, the Administrator of the DEA concludes that [123 I]ioflupane does not warrant control under the CSA.

Effect on Other Rulemakings

On November 25, 2014, DEA published an interim final rule waiving the requirement of DEA registration for certain entities that are authorized under other federal or state authorities to administer DaTscan. 79 FR 70085. If finalized, this proposal to remove [123 I]ioflupane from the schedules of controlled substances would make such waivers unnecessary. Therefore, if this action is finalized, DEA intends to withdraw the regulations established through that interim final rule.

Regulatory Analyses

Executive Orders 12866 and 15363

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 Start Printed Page 31525hearing,” which are conducted pursuant to the provisions of 5 U.S.C. 556 and 557. The CSA sets forth the criteria for scheduling a drug or other substance and for removing a drug or substance from the schedules of controlled substances. Such actions are exempt from review by the Office of Management and Budget (OMB) pursuant to section 3(d)(1) of Executive Order 12866 and the principles reaffirmed in Executive Order 13563.

Executive Order 12988

This regulation meets the applicable standards set forth in sections 3(a) and 3(b)(2) of Executive Order 12988 Civil Justice Reform 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

This rulemaking does not have federalism implications warranting the application of Executive Order 13132. The 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

This rule does not have tribal implications warranting the application of Executive Order 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) (RFA), 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. The purpose of this rule is to remove [123 I]ioflupane 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 [123 I]ioflupane. Accordingly, it has the potential for some economic impact in the form of cost savings.

If finalized, the proposed rule will affect all persons who would handle, or propose to handle, [123 I]ioflupane. Due to the wide variety of unidentifiable and unquantifiable variables that potentially could influence the distribution and administration rates of new molecular entities, the DEA is unable to determine the number of entities and small entities which might handle [123 I]ioflupane.

Although the DEA does not have a reliable basis to estimate the number of affected entities and quantify the economic impact of this proposed rule, a qualitative analysis indicates that, if finalized, this rule is likely to result in some cost savings for the healthcare industry. The affected entities will continue to meet existing Federal and/or state requirements applicable to those who handle radiopharmaceutical substances, including licensure, security, recordkeeping, and reporting requirements, which in many cases are more stringent than the DEA's requirements. However, the DEA estimates cost savings will be realized from the removal of the administrative, civil, and criminal sanctions for those entities handling or proposing to handle [123 I]ioflupane, in the form of saved registration fees, and the elimination of additional physical security, recordkeeping, and reporting requirements.

Because of these facts, this rule will not result in a significant economic impact on a substantial number of small entities.

Unfunded Mandates Reform Act of 1995

On the basis of information contained in the “Regulatory Flexibility Act” section above, the DEA has determined and certifies pursuant to the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1501 et seq., 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 for inflation) in any one year * * * .” Therefore, neither a Small Government Agency Plan nor any other action is required under provisions of UMRA.

Paperwork Reduction Act

This action does not impose a new collection of information requirement under the Paperwork Reduction Act, 44 U.S.C. 3501-3521. This action would not impose recordkeeping or reporting requirements on State or local governments, individuals, businesses, or organizations. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number.
