Study Notes
Introduction to Biomanufacturing BE308
- Course title: Introduction to Biomanufacturing
- Course number: BE308
- Instructor: Dr. Sumit Murab
- Instructor email: [email protected]
- Website: https://sites.google.com/iitmandi.ac.in/murab-group
- Focus: Industrial Scaleup
Regulators in India
- CDSCO (Central Drug Standard Control Organization): Regulatory authority in India focusing on drug safety and efficacy.
- DBT (Department of Biotechnology) and RCGM (Review Committee of Genetic Manipulation): Responsible for pre-clinical evaluation of recombinant biologics.
- Aims to ensure safety, quality, and efficacy of similar biological products.
- Authorize and comply with regulatory requirements for similar biologics in India.
Applicable Regulations and Guidelines
- Governed by the Drugs and Cosmetics Act, 1940, the Drugs and Cosmetics Rules, 1945.
- Environment (Protection) Act, 1986 Rules for hazardous microorganisms, genetically engineered organisms or cells (1989).
- Relevant guidelines include:
- Recombinant DNA Safety Guidelines (1990).
- Guidelines for generating preclinical and clinical data for rDNA vaccines, diagnostics, and other Biologicals (1999).
- CDSCO guidance for industry (2008)
- Guidelines & Handbook for Institutional Biosafety Committees (IBSCs) (2011)
- Guidelines on Similar Biologics: Regulatory Requirements for Marketing authorization in India (2012)
Competent Authorities
- Institutional BioSafety Committee (IBSC): Responsible for biosafety review and authorization of microorganisms and genetically engineered organisms for research.
- Review Committee on Genetic Manipulation (RCGM): Authorizes research, development, exchange of genetically engineered cell banks, and pre-clinical evaluation data.
- Genetic Engineering Appraisal Committee (GEAC): Statutory body for reviewing genetically modified organisms/living modified organisms activities.
- Central Drugs Standard Control Organization (CDSCO): Apex regulatory body for clinical trial approvals, drug import/export, and manufacturing/marketing approvals.
Principles for Development of Similar Biologics
- Mandatory to prove similar biologics meet acknowledged levels of the reference biologic to ensure public health and consistency in production.
- Selecting a reference biologic is crucial depending on DBT and CDSCO guidelines.
- Licensed, well-distributed reference biologics are preferred for minimum 4 years.
- Same reference biologic should be used in the complete study.
Manufacturing Process
- Stable and robust manufacturing process is essential.
- Identical host cell lines are crucial if used for the reference biologic.
- ICH guidelines (Q5A, Q5B, Q5D) are guidelines for cell bank initiation and characterization.
- Molecular biological considerations, such as host cell cultures, vectors, and gene sequences, are critical.
- Fermentation process must be controlled, replicable and scalable, tracking factors such as pH, temperature, and oxygen levels.
- Data on all manufacturing batches must be maintained.
Downstream Process Development
- Focuses on protein purification processes.
- Describes the purification steps & refolding process.
- Dose-response curve is essential to describe the activity of the product at various doses.
- Continuous recovery over three batches required during the purification process.
- Maintaining GMP during the manufacture & production process. Record detailed descriptions of drug substances, critical quality attributes of the product, and critical process parameters.
- Critical data for comparability (clinical scale vs reference biologics), stability, and validation batches.
Quality Based Considerations for Similar Biologics
- Analytical Methods: Employ multiple, orthogonal methods for characterizing products (batch release, stability studies, in-process controls); follow ICH Q2, Q5C, Q6B guidelines.
- Product Characterization: Detail physicochemical, biological, immunological properties; include functional assays, purity, and contamination assessments.
- Structural and Physicochemical Properties (primary and higher order structure). Accuracy and precision in measurements.
- Biological Activity: In accordance with reference biologic; matching the mechanism of action, and considering clinical effects.
- Immunological Properties: Understand associated impurities, post-translational modifications, and factors such as specificity, affinity, and binding strength analysis.
- Purity and Impurities: Identification of product variants, impurities including aggregated products, host-cell related impurities, and process-related impurities.
- Specifications: Specifications methodologies are distinct from analytical methods, with acceptance limits based on available data.
- Stability: Shelf life regulation in conditions/containers identified by ICH Q5C guidelines.
- Quality Comparability Study: Compare the similar biologic to a reference biologic using appropriate methodologies in accordance with CDSCO's guidance for industry 2008. Three batches for quality consistency assessment.
Data Requirements for Pre-Clinical Studies
- A): Applicant provides pre-clinical study protocols, toxicology study data (drug administration, dosage, absorption, elimination rate, mechanism of action, toxicity).
- B): Includes pharmacodynamic studies. In-vitro studies for cell proliferation & in-vivo studies for biological and pharmacodynamic activity assessment per rodent & non-rodent species guidelines. Includes toxicity studies. The study procedure and animal selection justification is mandatory.
- C): Reporting on the immune response in animals, antibody response, serum sample analysis (comparing with reference biologic responses). Reporting to RCGM for review.
Data Requirements for Clinical Trial Application
- A): Pharmacokinetic studies comparing similar & reference biologic in healthy volunteers including half-life, linearity, and route/conditions for administration
- B): Pharmacodynamic studies comparing similar & reference biologic in healthy animals. Assessing response & efficacy within a phase III design. Should be contrast in nature.
- C): Confirmatory safety and efficacy studies: matching clinical compatibility and end points. Systemic and functional comparability of similar and reference biologic.
- D): Post-marketing safety and immunogenicity data based on pre-clinical and post-clinical data.
Data Requirements for Marketing Authorization Application
- Pharmacovigilance plan; including ADR reporting within 15 days to CDSCO, and Periodic Safety Update Reports (PSURs) submitted every six months.
- Post-market studies: detailed studies noted in the Pharmacovigilance plan, submitted to CDSCO. Records related to risk assessments.
