SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Interpreting Sameness of Monoclonal Antibody Products Under 
the Orphan Drug Regulations.''
    On July 26, 1999 (64 FR 40381), FDA announced the availability of 
the draft version of this guidance. The public comment period closed on 
October 25, 1999. A number of comments were received from the public, 
all of which the Agency considered carefully as it finalized the 
guidance and made appropriate changes. Any changes to the guidance were 
minor and made to clarify statements in the draft guidance.
    In the Federal Register of December 29, 1992 (57 FR 62076), FDA 
published the orphan drug regulations final rule, and on June 12, 2013 
(78 FR 35117) the Agency finalized certain amendments to the final rule 
in order to clarify regulatory provisions and make minor improvements 
to address issues that have arisen since 1992. The final rule 
established in part 316 (21 CFR part 316) regulations that prescribe 
certain incentives for the development of ``orphan drugs'', drugs which 
are intended for use in rare diseases or conditions. One of the 
incentives for orphan drug development is to obtain exclusive approval 
for the pioneer product for a period of 7 years during which no 
approval will be given to a subsequent sponsor of the same drug product 
for the same indication unless it proves to be clinically superior, as 
defined in Sec.  316.3(b)(3). In determining whether or not two 
products would be considered the same, FDA recognized that different 
criteria were necessary for macromolecules versus small molecules 
(Sec.  316.3(b)(13)).
    Macromolecules include a variety of structures including proteins, 
nucleic acids, carbohydrates and closely related, complex, partly 
definable drugs such as live viral vaccines. The current definition of 
sameness for protein drugs (Sec.  316.3(b)(13)(ii)(A)), however, does 
not consider the unique nature of antibodies. This final document is 
intended to describe FDA's thinking on the criteria by which two 
monoclonal antibody products would be considered the same under the 
Orphan Drug Act and its implementing regulations.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
Agency's current thinking on Interpreting Sameness of Monoclonal 
Antibody Products Under the Orphan Drug Regulations. 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 and regulations.

II. Comments

have been approved under OMB control numbers 0910-0167 (21 CFR part 
316), 0910-0001 (21 CFR part 314), and 0910-0014 (21 CFR part 312).
