IV., V. & VI. EFFECTIVENESS, ANIMAL SAFETY AND HUMAN SAFETY
The safety and efficacy data upon which this application was approved are found in NADA 12-491 and 41-275 for Elanco Products Company, and are summarized in an FOI Summary filed with the Dockets Management Branch under the generic name of the drugs.
VII. AGENCY CONCLUSION
Approval of this application is based on safety and effectiveness data contained in Elanco Products Company's approved NADA's 12-491 and 41-275. Use of the data in NADA's 12-491 and 41-275 to support this application has been authorized by Elanco. This approval does not change the approved use of the drug. Consequently, approval of this NADA poses no increased human risk from exposure to residues of the animal drug, nor does it change the conditions of the drug's safe use in the target animal species. Accordingly, under the Center's supplemental approval policy (42 FR 64367), this is equivalent to a Category II supplemental approval which does not require reevaluation of the safety and effectiveness data in the original approval.
