Establishment of the Office of Therapeutic Products

The mission of the Center for Biologics Evaluation and Research (CBER) is to protect and enhance public health through the regulation of biological and related products including blood, vaccines, allergenics, tissues, and cellular and gene therapies. CBER is making changes to its organizational structure in order to address the substantial growth in the development of innovative, novel products and the ever-changing public health landscape.

In order to meet these challenges head on, CBER has established the new Office of Therapeutic Products (OTP). This new super office is the result of a reorganization of the Center’s Office of Tissues and Advanced Therapies and includes six new offices within the super office structure. This reorganization creates flexibility and capacity for future growth in the number of Full-Time Employee (FTE) positions as CBER works to meet the commitments and hiring goals outlined in the Prescription Drug User Fee Agreement (PDUFA) for fiscal years 2023-2027. The structural changes improve discipline alignment, increase review capacity, and enhance expertise in cell and gene therapies. Additional review staff and supervisory positions will not only help to address the increased workload but will also enhance the timeliness and consistency of the office’s interactions with sponsors and provide advancement opportunities to facilitate recruitment and retention of highly qualified staff.

OTP Organization Question and Answers

  1. What is the structure of the new OTP?
    • The Office of Tissues and Advanced Therapies (OTAT) was reorganized to become the Office of Therapeutic Products (OTP) and transitioned into a super office structure. New offices created within the super office structure align disciplines and product types, allowing our workforce to address the exponential growth in cell and gene therapies. This updated structure will enable OTP to:
      • Provide oversight and coordination across programs
      • Ensure flexibility for current and future growth in staff
      • Distribute workload more evenly
      • Support industry needs and commitments
      • Enhance expertise in highly specialized disciplines

    • Within OTP, six (6) Offices have been established:
      • Office of Gene Therapy Chemistry, Manufacturing, and Controls (CMC)
      • Office of Cellular Therapy and Human Tissue CMC
      • Office of Plasma Protein Therapeutics CMC
      • Office of Clinical Evaluation
      • Office of Pharmacology/ Toxicology
      • Office of Review Management and Regulatory Review

  2. How is hiring being addressed in relation to implementation of the new super office?
    • The new super office is scheduled to be implemented on February 26, 2023. The Center is actively working to fill new leadership positions created through the establishment of the new super office structure. While permanent selections are being finalized, individuals will be identified for acting positions. The Center continues to fill vacancies across the office to ensure adequate staffing to address the workload.

  3. How will this affect processes and communications with sponsors?
    • A goal of the reorganization process is to enhance the timeliness and consistency of communication with sponsors. This webpage provides sponsors with information on the organization.

  4. How do the new structural changes impact current processes and communications between sponsors and FDA?
    • The first point of contact will remain the regulatory project manager (RPM) previously assigned to a submission and each letter a sponsor receives will continue to identify that point of contact. CBER will update its website to reflect the new organizational leadership and provide additional contact information.
    • Submissions will be routed within OTP to ensure they are sent to the appropriate office in the new structure.

  5. Will BLA or IND applications that were under review in OTAT prior to the reorganization be affected? Will the processing of these applications take longer because of these changes?
    • OTP’s goal is to maintain review teams for existing applications throughout the reorganization. However, the responsible offices and divisions, as well as the signatory authority responsible for existing applications, may change – this will be determined by several factors, including how far along the review of the application is at the time of the reorganization.
    • OTP is committed to meeting all statutory commitments.

  6. Will there be changes to CBER’s Standard Operating Policies and Procedures (SOPPs) as well as guidance documents related to INDs and marketing applications?
    • CBER SOPPs and guidance documents related to INDs and marketing applications may be updated as a result of the reorganization to reflect new organizational titles and processes. CBER and OTP have a team dedicated to administrative activities. Consistent with our good guidance practices, we welcome comments on our guidance documents. Updated documents and policies and procedures will be posted on the FDA website.

  7. Where should interested parties go for more information?
    • We will continue to post information and updates about the organization on the CBER webpage. If you have specific questions, please reach out to [email protected].
