In accordance with the freedom of information provisions of 21 CFR

Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for
a 3-year period of exclusivity beginning April 10, 1997, because the

drugs involved, and studies of animal safety, required for approval of
the application and conducted or sponsored by the applicant.
