                        TITLE 21--FOOD AND DRUGS
 
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN 
                          SERVICES (CONTINUED)
 
PART 361_PRESCRIPTION DRUGS FOR HUMAN USE GENERALLY RECOGNIZED AS SAFE AND 
 
Sec.  361.1  Radioactive drugs for certain research uses.

    (a) Radioactive drugs (as defined in Sec.  310.3(n) of this chapter) 
are generally recognized as safe and effective when administered, under 
the conditions set forth in paragraph (b) of this section, to human 
research subjects during the course of a research project intended to 
obtain basic information regarding the metabolism (including kinetics, 
distribution, and localization) of a radioactively labeled drug or 
regarding human physiology, pathophysiology, or biochemistry, but not 
intended for immediate therapeutic, diagnostic, or similar purposes or 
to determine the safety and effectiveness of the drug in humans for such 
purposes (i.e., to carry out a clinical trial). Certain basic research 
studies, e.g., studies to determine whether a drug localizes in a 
particular organ or fluid space and to describe the kinetics of that 
localization, may have eventual therapeutic or diagnostic implications, 
but the initial studies are considered to be basic research within the 
meaning of this section.
    (b) The conditions under which use of radioactive drugs for research 
are considered safe and effective are:
    (1) Approval by Radioactive Drug Research Committee. A Radioactive 
Drug Research Committee, composed and approved by the Food and Drug 
Administration in accordance with paragraph (c) of this section, has 
determined, in accordance with the standards set forth in paragraph (d) 
of this section, that:
    (i) The pharmacological dose is within the limits set forth in 
paragraph (b)(2) of this section;
    (ii) The radiation dose is within the limits set forth in paragraph 
(b)(3) of this section;
    (iii) The radiation exposure is justified by the quality of the 
study being undertaken and the importance of the information it seeks to 
obtain;
    (iv) The study meets the other requirements set forth in paragraph 
(d) of this section regarding qualifications of the investigator, proper 
licensure for handling radioactive materials, selection and consent of 
research subjects, quality of radioactive drugs used, research protocol 
design, reporting of adverse reactions, and approval by an appropriate 
Institutional Review Committee; and
    (v) The use of the radioactive drug in human subjects has the 
approval of the Radioactive Drug Research Committee.

[[Page 320]]

    (2) Limit on pharmacological dose. The amount of active ingredient 
or combination of active ingredients to be administered shall be known 
not to cause any clinically detectable pharmacological effect in human 
beings. If the same active ingredients (exclusive of the radionuclide) 
are to be administered simultaneously, e.g., under a ``Investigational 
New Drug Application'' or for a therapeutic use in accordance with 
labeling for a drug approved under part 314 of this chapter, the total 
amount of active ingredients including the radionuclide shall be known 
not to exceed the dose limitations applicable to the separate 
administration of the active ingredients excluding the radionuclide.
    (3) Limit on radiation dose. The amount of radioactive material to 
be administered shall be such that the subject receives the smallest 
radiation dose with which it is practical to perform the study without 
jeopardizing the benefits to be obtained from the study.
    (i) Under no circumstances may the radiation dose to an adult 
research subject from a single study or cumulatively from a number of 
studies conducted within 1 year be generally recognized as safe if such 
dose exceeds the following:

Whole body, active blood-forming organs, lens of the eye, and gonads:

------------------------------------------------------------------------
                                                                  Rems
------------------------------------------------------------------------
  Single dose.................................................         3
  Annual and total dose commitment............................         5
Other organs:
  Single dose.................................................         5
  Annual and total dose commitment............................        15
------------------------------------------------------------------------

    (ii) For a research subject under 18 years of age at his last 
birthday, the radiation dose shall not exceed 10 percent of that set 
forth in paragraph (b)(3)(i) of this section.
    (iii) All radioactive material included in the drug either as 
essential material or as a significant contaminant or impurity shall be 
included when determining the total radiation doses and dose 
commitments. Radiation doses from x-ray procedures that are part of the 
research study (i.e., would not have occurred but for the study) shall 
also be included. The possibility of followup studies shall be 
considered for inclusion in the dose calculations.
    (iv) Numerical definitions of dose shall be based on an absorbed 
fraction method of radiation absorbed dose calculation, such as the 
system set forth by the Medical Internal Radiation Dose Committee of the 
Society of Nuclear Medicine, or the system set forth by the 
International Commission on Radiological Protection.
    (c) A Radioactive Drug Research Committee, in order to comply with 
paragraph (b)(1) of this section, shall be composed, shall function, and 
shall obtain and maintain approval of the Food and Drug Administration 
in conformity with the following:
    (1) Membership. A Radioactive Drug Research Committee shall consist 
of at least five individuals. Each committee shall include the following 
three individuals: (i) A physician recognized as a specialist in nuclear 
medicine, (ii) a person qualified by training and experience to 
formulate radioactive drugs, and (iii) a person with special competence 
in radiation safety and radiation dosimetry. The remainder of the 
committee shall consist of individuals qualified in various disciplines 
pertinent to the field of nuclear medicine (e.g., radiology, internal 
medicine, clinical pathology, hematology, endocrinology, radiation 
therapy, radiation physics, radiation biophysics, health physics, and 
radiopharmacy). Membership shall be sufficiently diverse to permit 
expert review of the technical and scientific aspects of proposals 
submitted to the committee. The addition of consultants in other 
pertinent medical disciplines is encouraged. A Radioactive Drug Research 
Committee shall be either associated with a medical institution operated 
for care of patients and with sufficient scientific expertise to allow 
for selection of committee members from its faculty, or with a committee 
established by a State authority to provide advice on radiation health 
matters. Joint committees involving more than one medical institution 
which have been established in order to achieve a high level and 
diversity of experience will be acceptable. The Director of the Center 
for Drug Evaluation and Research may modify any of the foregoing 
requirements in a

[[Page 321]]

particular situation where alternative factors provide substantially the 
same composition and association.
    (2) Function. Each Radioactive Drug Research Committee shall select 
a chairman, who shall sign all applications, minutes, and reports of the 
committee. Each committee shall meet at least once each quarter in which 
research activity has been authorized or conducted. A quorum consisting 
of more than 50 percent of the membership must be present with 
appropriate representation of the required fields of specialization. 
Minutes shall be kept and shall include the numerical results of votes 
on protocols involving use in human subjects. No member shall vote on a 
protocol in which he is an investigator.
    (3) Reports. Each Radioactive Drug Research Committee shall submit 
an annual report on or before January 31 of each year to the Food and 
Drug Administration, Center for Drug Evaluation and Research, HFD-160, 
5600 Fishers Lane, Rockville, MD 20857. The annual report shall include 
the names and qualifications of the members of, and of any consultants 
used by, the Radioactive Drug Research Committee, and, for each study 
conducted during the preceding year, a summary of information presented 
in the following format:

                                                            Investigator
________________________________________________________________________
                                              Chairman, Radioactive Drug
                                                      Research Committee


At any time a proposal is approved which involves exposure either of 
more than 30 research subjects, or of any research subject under 18 
years of age, the committee shall immediately submit to the Food and 
Drug Administration a special summary of information in the format shown 
in this paragraph. Contents of these reports are available for public 
disclosure, unless confidentiality is requested by the investigator and 
it is adequately shown by the investigator that the report constitutes a 
trade secret or confidential commercial information as defined in Sec.  
20.61 of this chapter.
    (4) Approval. Each Radioactive Drug Research Committee shall be 
specifically approved by the Center for Drug Evaluation and Research of 
the Food and Drug Administration. Applications shall be submitted to the 
Food and Drug Administration, Center for Drug Evaluation and Research, 
HFD-160, 5600 Fishers Lane, Rockville, MD 20857, and shall contain the 
names and qualifications of the members of the committee,

[[Page 322]]

and a statement that the committee agrees to comply with the 
requirements set forth in this section. Approval shall be based upon an 
assessment of the qualifications of the members of the committee, and 
the assurance that all necessary fields of expertise are covered. 
Approval of a committee may be withdrawn at any time for failure of the 
committee to comply with any of the requirements of this section. 
Approval of a committee shall remain effective unless and until the FDA 
withdraws such approval. Changes in membership and applications for new 
members shall be submitted to the Food and Drug Administration as soon 
as, or before, vacancies occur on the committee.
    (5) Monitoring. The Food and Drug Administration shall conduct 
periodic reviews of approved committees. Monitoring of the activities of 
the committee shall be conducted through review of its annual report, 
through review of minutes and full protocols for certain studies, and 
through on-site inspections.
    (d) In making the determination required in paragraph (b)(1) of this 
section, a Radioactive Drug Research Committee shall consider the 
following requirements and assure that each is met:
    (1) Radiation dose to subjects. To assure that the radiation dose to 
research subjects is as low as practicable to perform the study and meet 
the criteria of Sec.  361.1(b)(3), the Radioactive Drug Research 
Committee shall require that:
    (i) The investigator provide absorbed dose calculations based on 
biologic distribution data available from published literature or from 
other valid studies.
    (ii) The investigator provide for an acceptable method of radioassay 
of the radioactive drug prior to its use to assure that the dose 
calculations actually reflect the administered dose.
    (iii) The radioactive drug chosen for the study has that combination 
of half-life, types of radiations, radiation energy, metabolism, 
chemical properties, etc., which results in the lowest dose to the whole 
body or specific organs with which it is possible to obtain the 
necessary information.
    (iv) The investigator utilize adequate and appropriate 
instrumentation for the detection and measurement of the specific 
radionuclide.
    (2) Pharmacological dosage. To determine that the amount of active 
ingredients to be administered does not exceed the limitations set forth 
in paragraph (b)(2) of this section, the committee shall require that 
the investigator provide pharmacological dose calculations based on data 
available from published literature or from other valid human studies.
    (3) Qualifications of investigators. Each investigator shall be 
qualified by training and experience to conduct the proposed research 
studies.
    (4) License to handle radioactive materials. The responsible 
investigator or institutions shall, in the case of reactor-produced 
isotopes, be licensed by the Nuclear Regulatory Commission or Agreement 
State to possess and use the specific radionuclides for research use or 
be a listed investigator under a broad license, or in the case of non-
reactor-produced isotopes, be licensed by other appropriate State or 
local authorities, when required by State or local law, to possess and 
use the specific radionuclides for research use.
    (5) Human research subjects. Each investigator shall select 
appropriate human subjects and shall obtain the review and approval of 
an institutional review committee that conforms to the requirements of 
part 56 of this chapter, and shall obtain the consent of the subjects or 
their legal representatives in accordance with part 50 of this chapter. 
The research subjects shall be at least 18 years of age and legally 
competent. Exceptions are permitted only in those special situations 
when it can be demonstrated to the committee that the study presents a 
unique opportunity to gain information not currently available, requires 
the use of research subjects less than 18 years of age, and is without 
significant risk to the subject. Studies involving minors shall be 
supported with review by qualified pediatric consultants to the 
Radioactive Drug Research Committee. Each female research subject of 
childbearing potential shall state in writing that she is not pregnant, 
or, on the basis of a pregnancy test be confirmed as not

[[Page 323]]

pregnant, before she may participate in any study.
    (6) Quality of radioactive drug. The radioactive drug used in the 
research study shall meet appropriate chemical, pharmaceutical, 
radiochemical, and radionuclidic standards of identity, strength, 
quality, and purity as needed for safety and be of such uniform and 
reproducible quality as to give significance to the research study 
conducted. The Radioactive Drug Research Committee shall determine that 
radioactive materials for parenteral use are prepared in sterile and 
pyrogen-free form.
    (7) Research protocol. No matter how small the amount of 
radioactivity, no study involving administration of a radioactive drug, 
as defined in Sec.  310.3(n) of this chapter, to research subjects under 
this section, shall be permitted unless the Radioactive Drug Research 
Committee concludes, in its judgment, that scientific knowledge and 
benefit is likely to result from that study. Therefore, the protocol 
shall be based upon a sound rationale derived from appropriate animal 
studies or published literature and shall be of sound design such that 
information of scientific value may result. The radiation dose shall be 
both sufficient and no greater than necessary to obtain valid 
measurement. The projected number of subjects shall be sufficient but no 
greater than necessary for the purpose of the study. The number of 
subjects shall also reflect the fact that the study is intended to 
obtain basic research information referred to in paragraph (a) of this 
section and not intended for immediate therapeutic, diagnostic or 
similar purposes or to determine the safety and effectiveness of the 
drug in humans for such purposes (i.e., to carry out a clinical trial).
    (8) Adverse reactions. The investigator shall immediately report to 
the Radioactive Drug Research Committee all adverse effects associated 
with the use of the radioactive drug in the research study. All adverse 
reactions probably attributable to the use of the radioactive drug in 
the research study shall be immediately reported by the Radioactive Drug 
Research Committee to the Food and Drug Administration, Center for Drug 
Evaluation and Research, HFD-160, 5600 Fishers Lane, Rockville, MD 
20857.
    (9) Approval by an institutional review board. The investigator 
shall obtain the review and approval of an institutional review board 
that conforms to the requirements of part 56 of this chapter.
    (e) The results of any research conducted pursuant to this section 
as part of the evaluation of a drug pursuant to part 312 of this chapter 
shall be included in the submissions required under part 312 of this 
chapter.
    (f) A radioactive drug prepared, packaged, distributed, and 
primarily intended for use in accordance with the requirements of this 
section shall be exempt from section 502(f)(1) of the act and Sec. Sec.  
201.5 and 201.100 of this chapter if the packaging, label, and labeling 
are in compliance with Federal, State, and local law regarding 
radioactive materials and if the label of the immediate container and 
shielded container, if any, either separate from or as part of any label 
and labeling required for radioactive materials by the Nuclear 
Regulatory Commission or by State or local radiological health 
authorities bear the following:
    (1) The statement ``Rx only'';
    (2) The statement ``To be administered in compliance with the 
requirements of Federal regulations regarding radioactive drugs for 
research use (21 CFR 361.1)'';
    (3) The established name of the drug, if any;
    (4) The established name and quantity of each active ingredient;
    (5) The name and half-life of the radionuclide, total quantity of 
radioactivity in the drug product's immediate container, and amount of 
radioactivity per unit volume or unit mass at a designated referenced 
time;
    (6) The route of administration, if it is for the other than oral 
use;
    (7) The net quantity of contents;
    (8) An identifying lot or control number from which it is possible 
to determine the complete manufacturing history of the package of the 
drug;
    (9) The name and address of the manufacturer, packer, or 
distributor;
    (10) The expiration date, if any;
    (11) If the drug is intended for parenteral use, a statement as to 
whether the contents are sterile;

[[Page 324]]

    (12) If the drug is for other than oral use, the names of all 
inactive ingredients, except that:
    (i) Trace amounts of harmless substances added solely for individual 
product identification need not be named.
    (ii) If the drug is intended for parenteral use, the quantity or 
proportion of all inactive ingredients, except that ingredients added to 
adjust pH or to make the drug isotonic may be declared by name and a 
statement of their effect; if the vehicle is water for injection, it 
need not be named. Provided, however, That in the case of containers too 
small or otherwise unable to accommodate a label with sufficient space 
to bear all such information, the information required by paragraphs (f) 
(1) and (12) of this section may be placed on the shielded container 
only.
