DIVISION OF LEGAL AND REGULATORY SUPPORT (DLRS) – Advises OGD regarding generic drug application-specific legal, regulatory, and policy issues and serves as agency experts on Hatch-Waxman and other generic drug regulatory issues. Tracks and helps expedite review of public health priority submissions, including for first generics and drug shortages, to help achieve timely approval of generic drug products. Advises and makes decisions on patent and exclusivity matters for brand and generic drugs and determines timing of generic drug approval.
DIVISION OF ORANGE BOOK PUBLICATION AND REGULATORY ASSESSMENT (DOBPRA) - Publishes and maintains the publication “Approved Drug Products with Therapeutic Equivalence Ratings” (the Orange Book), which provides a range of information on brand and generic drugs, including information regarding market availability, substitutability, drug patents and exclusivity, and ensures timely and accurate information is included in the Orange Book regarding all new drug approvals and therapeutic equivalence evaluations for multi-source products.
DIVISION OF POLICY DEVELOPMENT (DPD) – Provides strategic leadership and direction in the development, clearance, and implementation of regulations, guidances, policies, procedures, and other documents affecting the regulation of generic drug products. Collaborates with all FDA offices supporting the generic drug program to ensure timely implementation and fulfillment of FDA’s commitments pursuant to the Generic Drug User Fee Amendments (GDUFA). Ensures consistency across CDER policies and procedures affecting regulation of generic drug products, including development and implementation of policy solutions to address lifecycle management matters. Provides clarity to internal and external stakeholders on generic drug regulatory policies and procedures, including development and clearance of responses to inquiries from the executive branch, Congress, media, industry, and foreign governments.
Office of Regulatory Operations (ORO)
Edward “Ted” Sherwood, Director, Office of Regulatory Operations
LCDR Malik Imam, Pharm.D., Deputy Director
ORO consists of its own Immediate Office and three divisions:
DIVISION OF PROJECT MANAGEMENT (DPM) – Houses the Regulatory Project Managers (RPMs) who oversee the review of Abbreviated New Drug Applications (ANDAs) to ensure OGD meets GDUFA goal dates. Provides oversight across all review disciplines, by planning, organizing, prioritizing, and assigning ANDA review work. OGD Division of Project Management Contact List
DIVISION OF FILING REVIEW (DFR) - Ensures incoming ANDAs, relevant prior approval supplements (PASs) and amendments meet established standards for filing. Responds to requests from the Federal Trade Commission (FTC).
DIVISION OF LABELING REVIEW (DLR) - Reviews and approves all aspects of labeling associated with ANDA submissions; coordinates and consults with the new drug divisions when necessary, and monitors New Drug Application (NDA) labeling to advise generic drug applicants of correct model labeling.
Office of Research and Standards (ORS)
Rob Lionberger, Ph.D., Director, Office of Research and Standards
Lei Zhang, Ph.D., Deputy Director, Office of Research and Standards
ORS consists of an Immediate Office (IO), and three Divisions:
DIVISION OF THERAPEUTIC PERFORMANCE I (DTP I) – Focuses on complex products, non-oral delivery routes and drug-device combinations. Conducts and translates regulatory science research into product-specific guidances to provide clear pathways and establish standards to ensure therapeutic equivalence of generic versions of complex drug products. Leads the pre-ANDA meeting process to provide scientific advice to potential applicants on the development of complex products. Supports the ANDA assessment process through consults on complex products.
DIVISION OF THERAPEUTIC PERFORMANCE II (DTP II) – Focuses on oral drug products. Leverages expertise in clinical pharmacology, formulation science, bioanalytical methods, and human subject protection to conduct research that ensures therapeutic equivalence of generic versions of oral drug products and provide timely product specific guidance to generic drug developers. Leads the product-specific guidance development process and manages clinical issues related to product-specific guidance development and pre-application scientific advice. Supports the ANDA assessment process through consults on novel approaches to bioequivalence of oral drug products.
DIVISION OF QUANTITATIVE METHODS AND MODELING (DQMM) – Conducts research, develops and implements quantitative pharmacology and physiologically- and mechanistically-based models to ensure therapeutic equivalence and optimize bioequivalence evaluation approaches for generic drugs. Leads the development of novel data analytics approaches (e.g., big data tools) for in vitro, in vivo and post-market ANDA assessment decisions and generic drug program process optimizations. Supports the ANDA assessment process through consults on the use of quantitative methods in ANDA submissions.
