Routing and Signature Requirements for Regulatory Letters (Delegation of Signature Authority in OVRR)

SOPP 9201

Version #1

April 7, 1999


  1. Purpose
  2. Describes the routing and signature authority for regulatory letters in the Office of Vaccines Research and Review (OVRR), Center for Biologics Evaluation and Research (CBER).

  3. Definitions
  4. Some of the regulatory letters available to reviewers are described below.

    Approval Letter - An approval letter and accompanying issuance of appropriate license(s) will constitute the final action on the outstanding reference number(s) following completion of all aspects of the review process for the license application/supplement, including testing of submitted product lots, pre-licensing inspection, if needed, and evaluation of final printed labeling or a suitable alternative.

    Clinical Hold Letter - A letter that contains an explanation of the basis for the clinical hold action. A complete clinical hold represents a hold of all clinical work requested under the IND. The clinical hold may be a partial clinical hold where only part of the clinical work requested under the IND, e.g., a specific protocol, is not allowed to proceed; however, other protocols are allowed to proceed under the IND. If only part of a protocol is allowed to proceed, with progress to the next part contingent upon FDA review/approval of additional data, this is also a partial hold. In contrast, if the Agency has told a sponsor that the sponsor needs to review results of a clinical study (or pre-clinical data) before proceeding, there is no clinical hold.

    Note: Clinical Hold is an order issued by FDA to the sponsor of an IND to delay a proposed clinical investigation or to suspend an ongoing clinical investigation

    Complete Response Letter - When the complete review indicates that there are deficiencies remaining which preclude the approval of the application or supplement at that time this letter will be issued. The Complete Response Letter will summarize all of the deficiencies remaining, and where appropriate, describe actions necessary to place the application/supplement in a condition for approval.

    Discipline Review Letter - This letter is used to convey early thoughts on possible deficiencies found by a discipline review team for its portion of the pending application at the conclusion of the discipline review. These letters are not considered to be action letters because they do not represent a complete review of the submission and therefore do not stop the User Fee Review Clock.

    IND Letters - A type of regulatory letter used in response to Investigational New Drug (IND) applications.

    Information Request or Deficiency Letter - This letter notifies the applicant that CBER needs additional information or clarification of the data submitted to a license application or supplement. Information Request or Deficiency Letters are not considered to be action letters because they do not represent a complete review of the submission and therefore do not stop the User Fee Review Clock.

    License Application Letters - The types of letters that constitute complete Agency actions (for performance goal and review clock purposes) in response to the license application or supplement review process are complete response and approval letters. Action letters are the result of complete Agency review of applications or supplements and stop the review clock. Other non-action type letters are also described below.

    Refusal to File Letter - When the committee believes that a meaningful review of the application cannot be performed because the application is deficient or incomplete a Refusal to File letter is issued to the applicant. The committee is referred to the CBER Refusal to File Guidance Document, SOPP 8404.

    Response Letter to a Sponsor's Complete Response - A letter to the sponsor from the FDA in response to a sponsor's complete response in which the sponsor

    1. is allowed to proceed under the IND as proposed by the sponsor (i.e., the clinical hold is lifted),
    2. is allowed to proceed with specific restrictions not proposed by the sponsor (i.e., a partial clinical hold), or
    3. is informed that studies under the IND still may not proceed.

    In the latter two cases, the letter will set forth as to why the clinical hold is being maintained. This letter should be issued to the sponsor within 30 days of receipt of the sponsor's complete response.

    Review Letters for INDs and Master Files - This letter notifies the applicant that CBER requires additional information/clarification about the data submitted to an IND or Master File. Letters may be issued at any time during the review of a MF or IND and their amendments. The letters may include requests for additional information, clarifications and confirmations of data and proposals, administrative actions and advice from OVRR on product development.

  5. Background
  6. OVRR issues a variety of regulatory letters, from action letters for product license applications and supplements to clinical hold letters for investigational new drug applications and amendments. It has been the policy in OVRR that all regulatory letters were signed by the Office Director. The exceptions to this were IND administrative letters such as reactivation letters or reference number assignment and filing letters for original applications and supplements. OVRR will delegate signature authority on non-administrative regulatory letters as outlined in this standard operating procedure. The Center Director continues to retain authority to issue biologics licenses for all new biological entities, as per CFR Title 21, Part 601, Subpart A, Section 601.4.

  7. Policy
  8. It is the policy of OVRR that all regulatory letters, including action letters and administrative letters, will be routed for appropriate review and/or signatures to assure concurrence with the issues described in each letter.

  9. Responsibilities and Procedures
  10. The Branch Chiefs in the Division of Vaccines and Related Products Applications (DVRPA) will sign above their signature blocks on all administrative regulatory letters such as reference number assignment letters, withdrawal letters for license applications and supplements, and filing letters. Acknowledgement letters for INDs and Master files, administrative letters for INDs (inactivation confirmation, exemption, pre-inactivation, pre-termination, reinstatement, report request, withdrawal confirmation, and waiver denied) will be signed by the DVRPA CSO/CST.

    All non-administrative regulatory letters such as complete response letters, clinical hold letters, refusal to file letters, information request letters and approval letters for applications and supplements will be routed in draft via e-mail to members of the review committee, the appropriate branch chief/lab chief, the appropriate Division Director(s), the Office Director, and the Associate Director for Regulatory Policy. E-mail turn-around time for IND letters will be 24 hours. Turn-around time for reviewing all other regulatory letters will be determined on a case-by-case basis with the goal of meeting the appropriate PDUFA and FDAMA milestones. No response received in the designated time frame will be regarded as indicating your concurrence. All regulatory letters will be issued from DVRPA.

    The following types of letters are covered in this section:

    • Complete Response Letters for Original License Applications and Supplements, Approval Letters and Refusal to File letters for Supplements
    • Discipline Review Letters for License Applications and Supplements
