[Code of Federal Regulations] [Title 21, Volume 7] [Revised as of April 1, 2008] From the U.S. Government Printing Office via GPO Access [CITE: 21CFR601.46] [Page 42] TITLE 21--FOOD AND DRUGS CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN SERVICES (CONTINUED) PART 601_LICENSING--Table of Contents Subpart E_Accelerated Approval of Biological Products for Serious or Life-Threatening Illnesses Sec. 601.46 Termination of requirements. If FDA determines after approval that the requirements established in Sec. 601.42, Sec. 601.43, or Sec. 601.45 are no longer necessary for the safe and effective use of a biological product, it will so notify the applicant. Ordinarily, for biological products approved under Sec. 601.41, these requirements will no longer apply when FDA determines that the required postmarketing study verifies and describes the biological product's clinical benefit and the biological product would be appropriate for approval under traditional procedures. For biological products approved under Sec. 601.42, the restrictions would no longer apply when FDA determines that safe use of the biological product can be assured through appropriate labeling. FDA also retains the discretion to remove specific postapproval requirements upon review of a petition submitted by the sponsor in accordance with Sec. 10.30.
