IV. SUMMARY OF SAFETY AND EFFICACY

The safety and efficacy data upon which this application was approved are found in NADAs 10-918 and 11-948 for Elanco Products Company, and are summarized in an FOI Summary filed with the Dockets Management Branch (HFA-305) under the generic name of the drug.

 

V. AGENCY CONCLUSIONS

Approval of this application is based on safety and effectiveness data contained in Elanco's approved NADAs 10-918 and 11-948. 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 2 supplemental approval, which does not require reevaluation of the safety and effectiveness data in the original applications.
