These drug substances, consigned to individuals or processors who formulate and distribute animal drugs, may be adulterated under Section 501(a)(5) of the Act or misbranded under Section 502(f)(1). It is the responsibility of the distributor, whether the importer or some other firm, to assure that these drugs are only shipped to processors legally entitled to receive them. INAD - Sponsors of investigational new animal drug (INAD) exemptions frequently import from foreign countries either the dosage form or bulk drug substances for use in laboratory research or clinical trials. However, some importers have found that they could obtain entry of large amounts of unapproved new animal drugs if they would merely advise the FDA that the entry was for investigational use and supply an INAD number as reference. The FDA has learned that some of these have not been legitimate. Internally, the Center for Veterinary Medicine has tightened its procedures for the issuance of INAD numbers. The procedures in part implement the special notification requirements of 21 CFR 511.1(b)(9). This regulation pertains to the importation into the United States of a new animal drug for use in clinical trials. The regulation requires: 1. Prior notification to the FDA of the importer's intention to import the new animal drug for investigational use. This may be done by the INAD sponsor or his agent; or 2. The new animal drug for investigational use is shipped directly to an appropriate scientific institution which has submitted a statement to the FDA as sponsor of the clinical investigation. GUIDANCE: Bulk new animal drug substances labeled for further manufacturing or processing, or as harmless chemicals, and bearing some indication for veterinary use, consigned to veterinarians, veterinary drug distributors or processors, should be detained since they are unapproved new animal drugs in violation of 501(a)(5) unless the recipient holds an approved NADA or an INAD exemption for preparation of a finished dosage form drug or medicated feed premix from that particular bulk drug source, or an approval is not required at this time either by regulation or policy. Bulk new animal drug substances labeled for further manufacturing or processing, which do not bear any indications for veterinary use, may be misbranded under Section 502(f)(1) if they are intended for veterinary use or for further processing as animal drugs. Intended use may be established by showing the substances are consigned to veterinarians, veterinary drug distributors or processors, or by other evidence. Such drugs are in violation of Section 502(f)(1) because they do not bear adequate directions for use, except as specified in the following paragraph. 21 CFR 201.122 exempts a drug from adequate directions for use when labeled for further manufacturing and processing and when used to manufacture a new animal drug which is covered by an approved application or an investigational exemption under Part 511. 21 CFR 201.150 exempts a drug, which is intended to be further processed or manufactured, from adequate directions when it is shipped under the terms of a written agreement which, if followed, will assure the finished product is not adulterated or misbranded. Therefore, bulk new animal drug substances labeled for further manufacturing and processing and shipped to pharmaceutical manufacturers or processors are exempted from applicable provisions of section 501 and 502 only if shipped in accord with 21 CFR 201.122 and/or 21 CFR 201.150. ***Contact Michael Smedley, Division of Compliance(HFV-230) Center for Veterinary Medicine (301-827-0160)*** to determine the NADA approval status, the existence of a valid INAD(Investigational exemption) or to determine if the drugs are from approved foreign sources as specified in the approved NADA's. In addition, be alert to the importation of any new animal drug substance not consigned to an approved NADA holder which bears the trade name of an approved new animal drug. A number of bulk new animal drugs, generally labeled or declared as "harmless chemicals" or "for ornamental fish use only", or similar wording, may be actually intended for direct use in commercial food-fish aquaculture, despite their labeling, and are frequently diverted for such food fish use. These drugs may be adulterated under Section 501(a)(5) or misbranded under Section 502(f)(1), because of such actual intended use in aquaculture. Importer's claims for intended sale only for manufacture of, or direct user as, drugs for ornamental fish use should be considered suspicious at best. When such drugs are encountered, contact***Fran Pell, Division of Compliance (HFV-230), Center for Veterinary Medicine (301-827-0188)*** for guidance.
