I. Background

In the Federal Register of October 20, 2014 (79 FR 62635) FDA published the notice of availability for a draft guidance for industry #227 entitled “Two-Phased Chemistry, Manufacturing, and Controls (CMC) Technical Sections” giving interested persons until December 19, 2014, to comment on the draft guidance. FDA received one comment on the draft guidance and that comment was considered as the guidance was finalized. The guidance announced in this notice finalizes the draft guidance dated October 2014.

GFI #227 provides recommendations to sponsors submitting CMC data submissions to CVM to support approval of a new animal drug or abbreviated new animal drug. The two-phased process allows for two separate CMC submissions, each with its own review clock, and each including complete appropriate CMC information that is available for review at the time of submission. The guidance specifies the technical details of how the process works, the review clocks, the information that is appropriate for each technical section submission, and the possible review outcomes. The guidance also includes CVM's recommendations for meetings between the Division of Manufacturing Technologies and the sponsor during this process to ensure concurrence with the approach used for the CMC technical section.Start Printed Page 52767
