Swami , (M.Pharm, PGDIPR, PGDDRA) Mob.: +91-9881492626 Email- firstname.lastname@example.org By: Outline: Outline Overview of USFDA Framework Biological Products How are Biologics different? Therapeutic Biologicals - Examples Biologics in CBER or CDER Regulation for Drugs & Biologics Comparison to drugs Inspection Team Overview & Review Process NDA and BLA (Similarities and Differences) NDA/BLA Dossier content BLA Post-approval requirement Overview of Regulatory Framework - USFDA: Introduction: The FDA is part of the Health and Human services Department of the US Government . The FDA’s authority is based upon various laws and statutory documents . The Food and Drug Administration (FDA) has responsibility for regulation of drugs and Biological products which are manufactured and / or sold in the US . Overview of Regulatory Framework - USFDA Organizational Structure: Organizational Structure The FDA divided into following main Divisions or Centers . Center for Drug Evaluation and Research (CDER) Center for Biological Evaluation and Research (CBER) Center for Devices and Radiological Health (CDRH) Center for Veterinary Medicine (CVM) Office of Regulatory Affairs (ORA) Center for Food Safety and Applied Nutrition (CFSAN) National Center for Toxicological Research (NCTR) Center for Tobacco Products (CTP) Regulatory Submission: Regulatory Submission Center for Drug Evaluation and Research (CDER) : Center for Drug Evaluation and Research (CDER) The CDER is responsible for the regulation of Chemically – derived and most therapeutic Biological products , both New Drugs and Generics. Center for Biologics Evaluation and Research (CBER): Center for Biologics Evaluation and Research (CBER) The Mission of CBER is to protect and enhance public health through the regulation of certain therapeutic Biological Products as well as Blood Products , Vaccines, Tissue and Gene Therapy Products . Center for Devices and Radiological Health (CDRH): Center for Devices and Radiological Health (CDRH) The CDRH is responsible for the regulation of Medical Devices and Radiation Emitting products Center for Veterinary Medicine (CVM): Center for Veterinary Medicine (CVM) The CVM is responsible for the regulation of Animal or Veterinary Medicinal Products Office of Regulatory Affairs (ORA): Office of Regulatory Affairs (ORA) The ORA is the lead office for all field activities of the FDA. The duties and functions of ORA are divided between four main offices: Resource Management Regional Operation Criminal Investigations Enforcement. ORA regions are the Pacific , Southwest , Central , Southeast and Northeast regions of the US. Each region supports a number of local FDA offices. Office of Combination Products (OCP): Office of Combination Products (OCP) The OCP is responsible for general oversight of the agency’s regulation of combination products . The primary responsibilities for regulating specific combination products remain in one of the product centers – CDER, CBER, CDRH. The OCP also oversees multi center reviews of combination products, ensures consistent and appropriate post-approval regulation of combination products, and resolves disputes relating to combination products. Biological Product (Biologic / Biologics / Biological): Biological Product (Biologic / Biologics / Biological) Biological Product – a “ Virus, Therapeutic Serum, Toxin, Antitoxin, Vaccine, Blood, Blood Component or Derivative, Allergenic product, or Analogous product , applicable to the Prevention, Treatment or Cure of a Disease or Condition of human beings.” - As per Section 351 PHS Act Biologics vs. Drugs: Biologics vs. Drugs Biologic products generally more complex Many innovative products. Virtually every new biologic is a novel product (NME) Demonstration of product comparability is more difficult . Changes in manufacturing and scale-up can impede (obstruct) overall approval process . Biologics - Unique Aspects ! : Biologics - Unique Aspects ! Source material for biologics Potential for transmission of adventitious agents Bacteria, mycoplasma, fungi, viruses, TSE agents Need for in-process controls, validation process validation Heat Sensitive & susceptible to microbial contamination Controlled temperature during production Aseptic processing throughout Cannot terminally sterilize Formulations Majority Parenteral Issues with concentration, Multi-use vials PowerPoint Presentation: Pharmacokinetics Not well established May not be able to measure Potential Immunogenicity Desirable in vaccine strategies Unwanted effects in other settings (single or chronic-dosing) Altered PK Allergic, serum-sickness reactions Cross reactivity to normal, essential protein Limitations of non-clinical studies Species-specific antibody development Therapeutic Biologicals - Examples: Therapeutic Biologicals - Examples Cytokines Interferons- α, β, γ Interleukins- IL2, IL11 Hematopoietic growth factors Erythropoietins CSFs (Colony-stimulating factor) Enzymes Thrombolytics (e.g. streptokinase, TPA) Aldurazyme PowerPoint Presentation: Monoclonal Antibodies and related products Anti-EGFR (Cetuximab, Panitumumab) Anti-Alpha4 integrin (Natalizumab) Fusion proteins TNFR linked to Fc portion of human IgG (Etanercept) Fab Fragments Anti-VEGF (Ranibizumab) Anti-TNFα (certolizumab pegol) Oncology: Oncology Herceptin (trastuzumab) breast cancer, ushers in new area of highly targeted therapy Rituxan (rituximab) targets some lymphomas Zevalin (ibritumomab tiuxetan), monoclonal antibody targeted radiotherapy Campath (alemtuzumab) for CML (Chronic Myeloid Leukaemia) Avastin (Bavacuzimab Bavacuzimab) first line metastatic colorectal Cancer CBER or CDER: CBER or CDER An applicant must determine which division of the FDA to submit its application, as the Center for Biologics Evaluation and Research (CBER) and the Center for Drug Evaluation and Research (CDER) share responsibility for BLAs. Products Regulates by CBER : Products Regulates by CBER Allergenics Patch tests used to diagnose the causes of contact dermatitis. Extracts used to diagnose and treat rhinitis ("hay fever"), allergic sinusitis and conjunctivitis, and bee stings. Blood Blood and blood components used for transfusion, such as red blood cells, plasma, and platelets.e.g Immunoglobuilns. Devices Medical devices and tests used to safeguard blood, blood components, and cellular products from HIV, hepatitis, syphilis, and other infectious agents. Machines and related software used to collect blood and blood components. Gene Therapy Gene therapy products that replace a person's faulty or missing genetic material. Human Tissues and Cellular Products Human tissues for transplantation, such as skin, tendons, ligaments, and cartilage. Cellular products, such as human stem cells and pancreatic islets. Vaccines Vaccines used for the prevention of infectious diseases, such as mumps, measles, chicken pox, diphtheria, tetanus, influenza, hepatitis, smallpox, and anthrax. Xenotransplantation Products Xenotransplantation products use nonhuman tissues or organs into human recipients to treat human diseases such as liver failure, where human materials are not always available. Products Regulates by CDER : Products Regulates by CDER Therapeutic Biological Products Transferred to CDER Monoclonal antibodies for in vivo use. Proteins intended for therapeutic use, including cytokines (e.g. interferons), enzymes (e.g. thrombolytics), and other novel proteins, This category includes therapeutic proteins derived from plants, animals, or microorganisms, and recombinant versions of these products. Immunomodulators (non-vaccine and non-allergenic products intended to treat disease by inhibiting or modifying a pre-existing immune response). Growth factors, cytokines, and monoclonal antibodies intended to mobilize, stimulate, decrease or otherwise alter the production of hematopoietic cells in vivo. About Combination Products: About Combination Products Combination products are therapeutic and diagnostic products that combine drugs, devices, and/or biological products. Combination products involve components that would normally be regulated under different types of regulatory authorities, and frequently by different FDA Centers like CBER, CDER & CDRH. (i.e.,Drug/Device, Biologic/Device, Drug/Biologic, or Drug/Device/Biologic) Examples: Orthopedic implant with growth factors, Prefilled syringes Metered dose inhalers Transdermal patches Catheter with antimicrobial coating Regulation for Drugs & Biologics : Regulation for Drugs & Biologics PowerPoint Presentation: Product Type Drugs Products Biological Products FD & C Act √ √ PHS Act √ Component Jurisdiction √ √ Generic Equivalence √ Establishment Standards √ 21 CFR Part 211 √ √ 21 CFR Part 312 √ √ 21 CFR 600 √ 21 CFR 314 √ Law or Act.: Law or Act.

Label Requirements Specific information will be required depending on the type of BLA (e.g., Blood, Vaccines). NDA & BLA Application: NDA & BLA Application NDA and BLA are applications to market a new product. NDAs are used by CDER (center for drugs) and BLAs are used by CBER (center for biologics) The BLA requires close scrutiny of the manufacturing process and facilities , because of the greater variability of biological products. The application will include complete reports on all studies including patient listings , analysis according to the original statistical analysis protocol (SAP) as well as any exploratory analysis . PowerPoint Presentation: Although there is no regulatory mechanism in the U.S. to approve a generic version of a product that is marketed under a BLA , it is possible that a generic version of a biotech product that has been approved under an NDA could be approved. This confusing situation results because some biotech products are approved under NDAs while others are approved under BLAs. Review and approval of an NDA or BLA are based on the demonstration of safety and efficacy assessed from detailed reports of the clinical trials; particularly randomized controlled studies. Biological products are a subset of drugs; therefore both are regulated under provisions of the FDC Act. However, only biological products are licensed under section 351 of the PHS Act. (As previously noted, some therapeutic protein products are approved under section 505 of the FDC Act, not under the PHS Act.) Among other things, safety and purity assessments must consider the storage and testing of cell substrates that are often used to manufacture biologics. A potency assay is required due to the complexity and heterogeneity of biologics. Where, CFR – Code of Federal Regulations PDUFA – Prescription Drug User Fee Act.

The FDA regulates a wide range of biologics, including, but not limited to, vaccines, blood and blood by-products, certain monoclonal antibodies, tissue and cellular products. Within the FDA, the Center for Biologics , as well as the Center for Drug Evaluation and Research , can be responsible for the regulation of biologics. PowerPoint Presentation: Biologics are evaluated for market by the FDA through the filing of a Biologic License Application (BLA). A BLA, although similar to a New Drug Application (NDA), has its own set of intricate requirements. Applicant has to provided the information in an acceptable format, under the applicable regulations. However, applicants must be cognizant that unique and specific information will be required depending on the type of BLA (e.g., blood, vaccines). Archival and Review Copies of BLA: Archival and Review Copies of BLA Federal regulations require the submission of two copies of a BLA – Archival and Review. Archival Copy The archival copy is a complete copy of an application submission and must be bound in a BLUE cover jacket. The archival copy should include a cover letter to: confirm any agreements or understandings between the FDA and the applicant; identify a contact person regarding the application; identify the reviewing division of the FDA and the HFD number; and convey any other important information about the application. Review Copy: Review Copy The review copy is divided into six technical sections (“review sections”) and should be submitted with each review section separately bound in a specific color: Chemistry, Manufacturing and Controls (CMC) – RED; Nonclinical Pharmacology and Toxicology – YELLOW; Human Pharmacokinetics and Bioavailability – ORANGE; Microbiology (if required) – WHITE; Clinical Data – LIGHT BROWN; Statistical – GREEN. eCTD format starting no later than two years after the publication of the final guidance in the Federal Register, and final guidance is likely to enforce in mid-to-late 2015 BLA Post-Approval Requirements: BLA Post-Approval Requirements Required Annual Reports: Post Marketing Commitment (PMC) status (601.70) Other required submissions: Adverse Events (600.80) Distribution summary (600.81) Biologic Deviation Reports (600.14) Advertising and Promotional Labeling Periodic cGMP inspections Changes to be Reported (21CFR 601.12): Changes to be Reported (21CFR 601.12) Manufacturing Changes
