application is submitted under subsection (bX2) is bioequivalent to 
the approved new animal drug referred to in such application and 
that residues of the new animal drug are consistent with the 
tolerances established for such approved new animal drug but at a 
withdrawal period which is different than the withdrawal period 
approved for such approved new animal drug, the Secretary may 
establish, on the basis of information submitted, such different 
withdrawal period as the withdrawal period for the new animal 
drug for purposes of the approval of such application for such drug.

food safety studies (other than bioequivalence or residue studies) 
essential to the approval of the application and conducted or spon-
sored by the applicant, the Secretary may not make the approval of

bioequivalence or residue studies) essential to the approval of the 
supplement and conducted or sponsored by the person submitting 
the supplement, the Secretary may not make the approval of an 
application submitted under subsection OoX2) for a change approved 
in the supplement effective before the expiration of 3 years from the 
date of the approval of the supplement.

on approval of applications submitted under subsection Ot)X2) set 
forth in clause (ii) of this subparagraph shall be applicable to the 
subsection Ot)Xl) application. 
"(v) If an application (including any supplement to a new animal 
drug application) submitted under subsection (bXD for a new animal 
drug for a food-producing animal use, which includes an active 
ingredient (including any ester or salt of the active ingredient) 
which has been the subject of a waiver under subparagraph (BXiv) is 
approved after the date of enactment of this paragraph, and if the 
application contains reports of clinical or field investigations or 
human food safety studies (other than bioequivalence or residue 
studies) essential to the new approval of the application and con-
ducted or sponsored by the applicant, the Secretary may not make 
the approval of an application (including any supplement to such 
application) submitted under subsection (bX2) for the new conditions 
of approval of such drug in the subsection (bXD application effective 
before the expiration of five years from the date of approval of the 
application under subsection 0)X1) for such drug. The provisions of 
this paragraph shall apply only to the first approval for a food-
producing animal use for the same applicant after the waiver under 
subparagraph (BXiv). 
"(G) If an approved application submitted under subsection (bX2) 
for a new animal drug refers to a drug the approval of which was 
withdrawn or suspended for grounds described in paragraph (1) or 
(2) of subsection (e) or WEIS withdrawn or suspended under this 
subparagraph or which, as determined by the Secretary, has been 
withdrawn from sale for safety or effectiveness reasons, the ap-
proval of the drug under this paragraph shall be withdrawn or 
suspended— 
**(i) for the same period as the withdrawal or suspension 
under subsection (e) or this subparagraph, or 
"(ii) if the approved new animal drug has been withdrawn 
from sale, for the period of withdrawal from sale or, if earlier, 
102 STAT. 3980

"(i) The term 'bioequivalence' means the rate and extent to 
which the active ingredient or therapeutic ingredient is ab-
sorbed from a new animal drug and becomes available at the 
site of drug action. 
"(ii) A new animal drug shall be considered to be 
bioequivalent to the approved new animal drug referred to in its 
application under subsection (n) if— 
"(I) the rate and extent of absorption of the drug do not 
show a significant difference from the rate and extent of 
absorption of the approved new animal drug referred to in 
the application when administered at the same dose of the 
active ingredient under similar experimental conditions in 
either a single dose or multiple doses; 
"(II) the extent of absorption of the drug does not show a 
significant difference from the extent of absorption of the 
approved new animal drug referred to in the application 
when administered at the same dose of the active ingredi-
ent under similar experimental conditions in either a single 
dose or multiple doses and the difference from the approved 
new animal drug in the rate of absorption of the drug is 
intentional, is reflected in its proposed labeling, is not 
essential to the attainment of effective drug concentrations 
in use, and is considered scientifically insignificant for the 
drug in attaining the intended purposes of its use and 
preserving human food safety; or 
"(III) in any case in which the Secretary determines that 
the measurement of the rate and extent of absorption or 
excretion of the new animal drug in biological fluids is 
inappropriate or impractical, an appropriate acute pharma-
cological effects test or other test of the new animal drug 
and, when deemed scientifically necessary, of the approved 
new animal drug referred to in the application in the 
species to be tested or in an appropriate animal model 
does not show a significant difference between the new 
animal drug and such approved new animal drug when 
administered at the same dose under similar experimental 
conditions. 
If the approved new animal drug referred to in the application 
for a new animal drug under subsection (n) is approved for use 
in more than one animal species, the bioequivalency informa-
tion described in subclause (I), (II), and (III) shall be obtained for 
one species, or if the Secretary deems appropriate based on 
scientific principles, shall be obtained for more than one species. 
The Secretary may prescribe the dose to be used in determining 
bioequivalency under subclause (I), (II), or (III). To assure that 
the residues of the new animal drug will be consistent with the 
established tolerances for the approved new animal drug re-
ferred to in the application under subsection (bK2) upon the 
expiration of the withdrawal period contained in the applica-
tion for the new animal drug, the Secretary shall require 
bioequivalency data or residue depletion studies of the new 
animal drug or such other data or studies as the Secretary 
considers appropriate based on scientific principles. If the Sec-
retary requires one or more residue studies under the preceding 
PUBLIC LAW 100-670—NOV. 16, 1988 
102 STAT. 3981 
sentence, the Secretary may not require that the assay meth-
odology used to determine the withdrawal period of the new 
animal drug be more rigorous than the methodology used to 
determine the withdrawal period for the approved new animal 
drug referred to in the application. If such studies are required 
and if the approved new animal drug, referred to in the applica-
tion for the new animal drug for which such studies are re-
quired, is approved for use in more than one animal species, 
such studies shall be conducted for one species, or if the Sec-
retary deems appropriate based on scientific principles, shall be 
conducted for more than one species.".

patent infringement could reasonably be asserted if a person not
