                        TITLE 21--FOOD AND DRUGS
 
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN 
                          SERVICES (CONTINUED)
 
PART 310_NEW DRUGS--Table of Contents
 
        Subpart E_Requirements for Specific New Drugs or Devices
 
Sec.  310.503  Requirements regarding certain radioactive drugs.

    (a) On January 8, 1963 (28 FR 183), the Commissioner of Food and 
Drugs exempted investigational radioactive new drugs from part 312 of 
this chapter provided they were shipped in complete conformity with the 
regulations issued by the Nuclear Regulatory Commission. This exemption 
also applied to investigational radioactive biologics.
    (b) It is the opinion of the Nuclear Regulatory Commission, and the 
Food and Drug Administration that this exemption should not apply for 
certain specific drugs and that these drugs should be appropriately 
labeled for uses for which safety and effectiveness can be demonstrated 
by new drug applications or through licensing under the Public Health 
Service Act (42 U.S.C. 262 et seq.) in the case of biologics. Continued 
distribution under the investigational exemption when the drugs are 
intended for established uses will not be permitted.
    (c) Based on its experience in regulating investigational 
radioactive pharmaceuticals, the Nuclear Regulatory Commission has 
compiled a list of reactor-produced isotopes for which it considers that 
applicants may reasonably be expected to submit adequate evidence of 
safety and effectiveness for use as recommended in appropriate labeling. 
Such use may include, among others, the uses in this tabulation:

\1\ This item has been removed from the AEC list for kidney scans but is
  included as the requirements of this order are applicable.

    (d)(1) In view of the extent of experience with the isotopes listed 
in paragraph (c) of this section, the Nuclear Regulatory Commission and 
the Food and Drug Administration conclude that such isotopes should not 
be distributed under investigational-use labeling when they are actually 
intended for use in medical practice.
    (2) The exemption referred to in paragraph (a) of this section, as 
applied to any drug or biologic containing any of the isotopes listed in 
paragraph (c) of this section, in the ``chemical form'' and intended for 
the uses stated, is terminated on March 3, 1972, except as provided in 
paragraph (d)(3) of this section.
    (3) The exemption referred to in paragraph (a) of this section, as 
applied to any drug or biologic containing any of the isotopes listed in 
paragraph (c) of this section, in the ``chemical form'' and intended for 
the uses stated, for which drug a new drug application or a 
``Investigational New Drug Application'' was submitted prior to March 3, 
1972, or for which biologic an application for product license or 
``Investigational New Drug Application'' was submitted prior to March 3, 
1972, is terminated on August 20, 1976, unless an approvable notice was 
issued on or before August 20, 1976, in which case the exemption is 
terminated either upon the subsequent issuance of a nonapprovable notice 
for the new drug application or on November 20, 1976, whichever occurs 
first.
    (e) No exemption from section 505 of the act or from part 312 of 
this chapter is in effect or has been in effect for radioactive drugs 
prepared from accelerator-produced radioisotopes, naturally occurring 
isotopes, or nonradioactive substances used in conjunction with 
isotopes.
    (f)(1) Based on its experience in regulating investigational 
radioactive pharmaceuticals, the Nuclear Regulatory Commission has 
compiled a list of reactor-produced isotopes for which it considers that 
applicants may reasonably be expected to submit adequate evidence of 
safety and effectiveness for use as recommended in appropriate labeling; 
such use may include, among others, the uses in this tabulation:

    (2) In view of the extent of experience with the isotopes listed in 
paragraph (f)(1) of this section, the Nuclear Regulatory Commission and 
the Food and Drug Administration conclude that they should not be 
distributed under investigational-use labeling when they are actually 
intended for use in medical practice.
    (3) Any manufacturer or distributor interested in continuing to ship 
in interstate commerce drugs containing the isotopes listed in paragraph 
(f)(1) of this section for any of the indications listed, shall submit, 
on or before August 25, 1975 to the Center for Drug Evaluation and 
Research, Food and Drug Administration, 5600 Fishers Lane, Rockville, MD 
20857, a new drug application or a ``Investigational New Drug 
Application'' for each such drug for which the manufacturer or 
distributor does not have an approved new drug application pursuant to 
section 505(b) of the act. If the drug is a biologic, a 
``Investigational New Drug Application'' or an application for a license 
under section 351 of the Public Health Service Act shall be submitted to 
the Center for Biologics Evaluation and Research, Food and Drug 
Administration, 8800 Rockville Pike, Bethesda, MD 20014, in lieu of any 
submission to the Center for Drug Evaluation and Research.
    (4) The exemption referred to in paragraph (a) of this section, as 
applied to any drug or biologic containing any of the isotopes listed in 
paragraph (f)(1) of this section, in the ``chemical form'' and intended 
for the uses stated, is terminated on August 26, 1975 except as provided 
in paragraph (f)(5) of this section.
    (5)(i) Except as provided in paragraph (f)(5)(ii) of this section, 
the exemption referred to in paragraph (a) of this section, as applied 
to any drug containing any of the isotopes listed in paragraph (f)(1) of 
this section, in the ``chemical form'' and intended for the uses stated, 
for which drug a new drug application or ``Investigational New Drug 
Application'' was submitted to the Center for Drug Evaluation and 
Research on or before August 25, 1975 is terminated on August 20, 1976, 
unless an approvable notice was issued on or before August 20, 1976, in 
which case the exemption is terminated either upon the subsequent 
issuance of a nonapprovable notice for the new drug application or on 
November 20, 1976, whichever occurs first.
    (ii) The exemption referred to in paragraph (a) of this section, as

license or ``Investigational New Drug Application'' was submitted to the 
Center for Biologics Evaluation and Research on or before August 25, 
1975 is terminated on October 20, 1976, unless an approvable notice was 
issued on or before October 20, 1976, in which case the exemption is 
terminated either upon the subsequent issuance of a nonapprovable notice

research project, which use had been approved on or before July 25, 1975 
in accordance with 10 CFR 35.11 (or equivalent regulation of an 
Agreement State) is terminated on February 20, 1976 if the manufacturer 
of such drug or the sponsor of the investigation of such drug submits on
