| File No. | Previous sponsor | Product name | New sponsor | 21 CFR |
| --- | --- | --- | --- | --- |

As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these changes of sponsorship. Following the change of sponsorship of ANADA 200-582, Orkeo USA, Inc., is no longer the sponsor of an approved application.
**III. Withdrawals of Approval**
In addition, during September and October 2015, the following three sponsors have requested that FDA withdraw approval of the NADAs and ANADAs listed in the following table because the products are no longer manufactured or marketed:
| File No. | Sponsor | Product name | 21 CFR |
| --- | --- | --- | --- |
| 140-680 | Pharmgate LLC, 1015 Ashes Dr., suite 102, Wilmington, NC 28405 | TYLAN (tylosin phosphate) Premix | 558.625 |
| 140-681 | Pharmgate LLC, 1015 Ashes Dr., suite 102, Wilmington, NC 28405 | TYLAN SULFA G (tylosin phosphate and sulfamethazine) Premix | 558.630 |

| 200-383 | Bayer HealthCare LLC, Animal Health Division, P.O. Box 390, Shawnee Mission, KS 66201 | CLINDAROBE (clindamycin) Capsules | 520.446 |
Elsewhere in this issue of the *Federal Register* , FDA gave notice that approval of NADA 140-680, NADA 140-681, ANADA 200-028, and ANADA 200-383, and all supplements and amendments thereto, is withdrawn, effective December 21, 2015. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these voluntary withdrawals of approval.
**IV. Technical Amendments**
FDA has noticed that a previous sponsor of ANADA 200-383, Teva Canada Ltd., was no longer the sponsor of an approved application following a prior change of sponsorship. At this time, FDA is amending the regulation to remove the firm from the listings of sponsors of approved applications in 21 CFR 510.600. This action is being taken to improve the accuracy of the regulations.
FDA is also revising the special considerations for medicated feeds containing veterinary feed directive drugs to align with 21 CFR 558.6(a)(6), which was recently amended (80 FR 31708, June 3, 2015). This action is being taken to improve the consistency of the regulations.
This rule does not meet the definition of “rule” in 5 U.S.C. 804(3)(A) because it is a rule of “particular applicability”. Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.
**List of Subjects**
Administrative practice and procedure, Animal drugs, Labeling, Reporting and recordkeeping requirements.
Animal drugs.
