SUPPLEMENTARY INFORMATION:
I. Description of the Guidance
FDA is announcing the availability of a draft guidance document
entitled ``Developing Medical Imaging Drugs and Biologics.'' It
references other CDER and CBER guidance documents that relate to the
development of medical imaging drugs and biologics, including CBER's
``Points to Consider in the Manufacture and Testing of Monoclonal
Antibody Products for Human Use'' (62 FR 9196, February 28, 1997). The
draft guidance is intended to assist developers of drug and biological
products used for medical imaging, as well as radiopharmaceutical drugs
used in disease diagnosis, in planning and coordinating the clinical
investigations of, and submitting various types of applications for,
such products. The draft guidance applies to medical imaging drugs that
are used for diagnosis and monitoring and that are administered in
vivo. Such drugs include contrast agents used with medical imaging
techniques such as radiography, computed tomography, ultrasonography,
and magnetic resonance imaging, as well as radiopharmaceuticals used
with imaging procedures, such as single-photon emission computed
tomography and positron emission tomography. The draft guidance is not
intended to apply to possible therapeutic uses of these drugs or to in
vitro diagnostic products.
CDER's Division of Medical Imaging and Radiopharmaceutical Drug
Products presented a preliminary version of this draft guidance
document to the Medical Imaging Drug Advisory Committee (MIDAC) on
October 26, 1996. Following that meeting, FDA worked with MIDAC to
develop this draft guidance. As part of this process, FDA considered
proposals submitted by an ad hoc group representing contrast agent
manufacturers and by the Council on Radionuclides and
Radiopharmaceuticals, Inc.
On November 21, 1997, President Clinton signed into law the Food
and Drug Administration Modernization Act of 1997 (the Modernization
Act). Section 122(a)(1) of the Modernization Act directs FDA to issue
regulations on the approval of diagnostic radiopharmaceuticals. In the
Federal Register of May 22, 1998 (63 FR 28301), FDA published a
proposed rule on the evaluation and approval of in vivo
radiopharmaceuticals used in the diagnosis and monitoring of diseases.
The proposed rule describes certain types of indications for which FDA
would approve diagnostic radiopharmaceuticals and lists factors that
the agency would consider in evaluating the safety and effectiveness of
a diagnostic radiopharmaceutical under the Federal Food, Drug, and
Cosmetic Act (the act) or the Public Health Service Act (the PHS Act).
This draft guidance document provides information on how FDA intends to
interpret and apply various sections of the proposed rule.
In the Federal Register of August 3, 1998 (63 FR 41219), FDA
published a document extending the comment period on the proposed rule
on in vivo radiopharmaceuticals from August 5, 1998, to October 15,
1998. In a separate document published elsewhere in this issue of the
Federal Register, FDA is further extending the comment period to
November 16, 1998. FDA hopes that the issuance of this draft guidance
on medical imaging drugs and biologics, in conjunction with the
extension of the comment period on the proposed rule, will assist
interested persons in preparing their comments on the proposed rule.
Persons will have additional time to submit comments on the draft
guidance after the comment period on the proposed rule closes.
This draft level 1 guidance is being issued consistent with FDA's
good guidance practices (62 FR 8961, February 27, 1997). It represents
the agency's current thinking on the development of medical imaging
drugs and biologics. It does not create or confer any rights for or on
any person and does not operate to bind FDA or the public. An
alternative approach may be used if such approach satisfies the
requirements of the applicable statutes, regulations, or both.
II. Comments
Interested persons may, at any time, submit to the Dockets
Management Branch (address above) written comments on the draft
guidance document. Two copies of any comments are to be submitted,
except that individuals may submit one copy. Comments should be
identified with the docket number found in brackets in the heading of
this document. The draft guidance document and received comments may be
seen in the Dockets Management Branch between 9 a.m. and 4 p.m., Monday
through Friday.
III. The Paperwork Reduction Act of 1995
This draft guidance contains information collection provisions that
are subject to review by the Office of Management and Budget (OMB)
under the Paperwork Reduction Act of 1995 (the PRA) (44 U.S.C. 3501-
3520). A description of these provisions is provided in the following
paragraphs with an estimate of the annual reporting burden. Included in
the estimate is the time for reviewing the instructions, searching
existing data sources, gathering and maintaining the data needed, and
completing and reviewing each collection of information.
FDA invites comment on the following: (1) Whether the proposed
collection of information is necessary for the proper performance of
FDA's functions, including whether the information will have practical
utility; (2) the accuracy of FDA's estimate of the burden of the
proposed collection of information, including the validity of the
methodology and assumptions used; (3) ways to enhance the quality,
utility, and clarity of the information to be collected; and (4) ways
to minimize the burden of the collection on respondents, including
through the use of automated collection techniques, when appropriate,
and other forms of information technology.
Title: Draft Guidance for Industry on Developing Medical Imaging
Drugs and Biologics
Description: FDA is issuing a draft guidance on the development of
medical imaging drugs and biologics. The draft guidance is intended to
assist developers of drug and biological products used for medical
imaging, as well as radiopharmaceutical drugs used in disease
diagnosis, in planning and coordinating the clinical investigations of,
and submitting various types of applications for, such products. The
draft guidance provides information on
[[Page 55069]]
how the agency will interpret and apply provisions of the existing
regulations regarding the content and format of an application for
approval of a new drug (21 CFR 314.50) and the content of a biological
product application (21 CFR 601.25). In addition, the draft guidance
provides information on how the agency will interpret and apply the
proposed rule on the evaluation and approval of in vivo
radiopharmaceuticals used for diagnosis and monitoring (63 FR 28301).
The proposed rule, by adding part 315, would clarify existing FDA
requirements for the evaluation and approval of drug and biological
radiopharmaceuticals already in place under the authority of the act
and the PHS Act.
Existing regulations, which appear primarily in parts 314 and 601
(21 CFR parts 314 and 601), specify the information that manufacturers
must submit so that FDA may properly evaluate the safety and
effectiveness of new drugs and biological products. This information is
usually submitted as part of a new drug application (NDA) or a
biologics license application (BLA), or as a supplement to an approved
application. This draft guidance supplements these regulations. Under
the proposed rule and the draft guidance, information required under
the act and the PHS Act and needed by FDA to evaluate safety and
effectiveness would still have to be reported.
Description of Respondents: Manufacturers of medical imaging drugs
and biologics, including contrast drug products and diagnostic
radiopharmaceuticals.
Burden Estimate: The proposed rule on in vivo radiopharmaceuticals
used for diagnosis and monitoring sets forth an estimated annual
reporting burden on the industry that would result from that rulemaking
(63 FR 28301 at 28305 to 28306). This draft guidance on the development
of medical imaging drugs and biologics is in part intended to explain
how FDA will interpret and apply the proposed rule. Thus, the estimated
annual reporting burden of the draft guidance, as provided in the chart
below, is the same as that of the proposed rule, with one change. In
addition to the diagnostic radiopharmaceuticals that are the subject of
the proposed rule, the draft guidance also addresses the development of
contrast drug products, which FDA evaluates and approves under part
314, but which are not affected by the proposed rule.
The chart below provides an estimate of the annual reporting burden
for diagnostic radiopharmaceuticals and is based on the estimate
described in the proposed rule (63 FR 28301 at 28306). The chart also
provides an estimate for the annual reporting burden for contrast drug
products. FDA estimates that the potential number of respondents who
would submit applications or supplements for contrast drug products
would be one. Although FDA did not approve any NDA's for contrast drugs
(there are no biological contrast drug products) in fiscal year 1997
(FY 1997), for purposes of estimating the annual reporting burden, the
agency assumes that it will approve one contrast drug each fiscal year.
The annual frequency of responses for contrast drugs is estimated to be
one response per application or supplement. The hours per response,
which is the estimated number of hours that an applicant would spend
preparing the information to be submitted for a contrast drug in
accordance with this draft guidance, is estimated to be approximately
2,000 hours.
The draft guidance would not impose any additional reporting burden
because safety and effectiveness information is already required by
existing regulations. In fact, clarification by the draft guidance of
FDA's standards for evaluation of medical imaging drugs and biologics
is expected to reduce the overall burden of information collection. FDA
invites comments on this analysis of information collection burdens.

information.
In compliance with section 3507(d) of the PRA (44 U.S.C. 3507(d)),
the agency has submitted the information collection provisions of this
draft guidance to OMB for review. Interested persons are requested to
send comments on this information collection by November 13, 1998, to
the Office of Information and Regulatory Affairs, OMB, New Executive
Office Bldg., 725 17th St. NW., rm. 10235, Washington, DC 20503, Attn:
