Overview: GLP, GCP & GMP
What is Good Clinical Practice (GCP)?
Good Clinical Practice (GCP) is an international ethical and scientific quality standard for designing, conducting, recording, and reporting clinical trials involving human participants. It ensures protection of participant rights, safety, and well-being, and guarantees credible and reliable clinical data.
What is segregation?
Segregation refers to the physical or procedural separation of materials, products, and processes to prevent cross-contamination and mix-ups.
What precautions apply to injured personnel?
Personnel with open wounds must report the injury, cover it with a sterile waterproof dressing, and may be restricted from sterile or critical production areas. In some cases, reassignment is required to prevent contamination risk.
What is process validation?
Process validation is documented evidence demonstrating that a manufacturing process consistently produces products meeting predetermined quality criteria.
What is a patent?
A patent grants exclusive rights to an inventor to prevent others from making, using, or selling the invention for a limited period, usually 20 years.
What is Good Laboratory Practice (GLP)?
Good Laboratory Practice (GLP) is a quality system governing non-clinical safety studies. It ensures laboratory studies are conducted according to standardized procedures with proper documentation, traceability, and archiving to support regulatory submissions.
What is a Standard Operating Procedure (SOP)?
An SOP is a controlled document that describes step-by-step instructions for performing a task consistently and in compliance with GMP requirements.
Define a cleanroom.
A cleanroom is a controlled environment where airborne particulate and microbial contamination are maintained within specified limits. Cleanrooms are classified (e.g., ISO classes or Grades A–D) and use controlled airflow, filtration (HEPA), and environmental monitoring.
What is ISO 9001?
ISO 9001 is an international standard specifying requirements for a quality management system (QMS). It focuses on customer satisfaction, continual improvement, leadership engagement, and risk-based thinking.
What is a trademark?
A trademark protects brand identifiers such as names, logos, or symbols that distinguish goods or services in commerce.
Which institutions are responsible for GCP and the Declaration of Helsinki?
The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) develops and harmonises international GCP guidelines.
The World Medical Association (WMA) developed and maintains the Declaration of Helsinki, which outlines ethical principles for medical research involving human subjects.
Why are personnel controls essential in GMP and how are they controlled?
Personnel are a major contamination risk. Proper GMP training ensures staff understand procedures, hygiene standards, and documentation practices. Hygiene controls (gowning, handwashing, restricted access) prevent microbial and particulate contamination, protecting product quality and patient safety.
Why is environmental monitoring essential in sterile production?
Environmental monitoring ensures microbial and particulate levels remain within acceptable limits. It includes air sampling, surface sampling, and personnel monitoring to detect contamination risks before product compromise occurs.
Outline the steps in a product recall.
Identify defect → Assess risk → Notify regulatory authorities → Inform distributors/customers → Retrieve affected batches → Document actions → Investigate root cause → Implement corrective actions.
What is the difference between bioprospecting and biopiracy?
Bioprospecting is the lawful exploration of biodiversity for commercially valuable resources with benefit-sharing agreements. Biopiracy involves exploiting biological resources or indigenous knowledge without consent or compensation.
What events influenced the development of modern GCP principles?
The Nuremberg Trials exposed unethical human experimentation during World War II, leading to the Nuremberg Code and the principle of voluntary informed consent.
The Tuskegee Syphilis Study involved withholding treatment from Black men with syphilis without informed consent, highlighting the need for ethical oversight and participant protection. These events shaped modern research ethics and GCP frameworks.
Name and define three types of materials found in a pharmaceutical manufacturing facility.
Raw Materials (Starting Materials): Active pharmaceutical ingredients (APIs) and excipients used in production.
Packaging Materials: Primary (direct contact with product, e.g., blister packs) and secondary (outer cartons).
In-Process Materials / Bulk Product: Partially processed materials awaiting further manufacturing steps.
Differentiate between aseptic preparation and terminal sterilization.
Terminal sterilization sterilizes the product in its final container using methods such as steam or irradiation. Aseptic processing involves sterilizing components separately and assembling them in a sterile environment when terminal sterilization is not possible.
How is Risk Management implemented/applied in GMP?
Quality Risk Management uses tools like FMEA to identify hazards, assess severity and probability, implement control measures, and review effectiveness. It is proactive and lifecycle-based.
How does the Nagoya Protocol regulate commercialization?
It ensures prior informed consent and mutually agreed terms for access to genetic resources, requiring fair and equitable sharing of benefits arising from commercialization.
What are the three pillars of the Belmont Report and how are they applied?
Respect for Persons – Individuals must be treated as autonomous agents. This requires informed consent and additional protections for vulnerable populations.
Beneficence – Researchers must maximize benefits and minimize harm through proper risk–benefit assessment.
Justice – The benefits and burdens of research must be distributed fairly; participant selection should not exploit vulnerable groups.
Discuss how facility design, personnel flow, material flow, and equipment layout reduce contamination risk.
GMP facility design minimizes contamination through unidirectional personnel and material flow, air pressure differentials, classified clean areas, and dedicated equipment where necessary. Physical segregation prevents mix-ups. HVAC systems control particulate levels. Proper zoning reduces cross-contamination. Regulatory inspections assess layout to ensure compliance with GMP principles.
What must be included in a Standard Operating Procedure (SOP)?
Title and SOP number
Version number and revision history
Effective date
Purpose and scope
Responsibilities
Definitions (if applicable)
Detailed procedure steps
Required documentation/forms
References to regulations
Approval signatures
Evaluate the importance of validation and risk management in preventing patient harm.
Validation ensures processes are consistent and controlled, preventing variability that could compromise safety. Risk management identifies potential failures before harm occurs. Together they reduce recalls, regulatory sanctions, and patient injury, forming the backbone of pharmaceutical quality assurance.
What are the qualifying criteria and scope of protection under Plant Breeder’s Rights?
Novelty – The variety must not have been commercially exploited beyond a prescribed period before application.
Distinctness – It must be clearly distinguishable from any other known variety.
Uniformity – Plants within the variety must be sufficiently consistent in relevant characteristics.
Stability – The variety must remain true to its defined characteristics after repeated propagation.
