Key Principles of GCP

• Trials should adhere to the ethical principles outlined in the Declaration of Helsinki
• A trial should be initiated and continued only after review and approval/favorable opinion by an ethics committee/institutional review board (EC/IRB)
• All individuals involved in conducting a trial should be qualified by education, training, and experience
• Freely given informed consent should be obtained from every subject prior to clinical trial participation
• Clinical trial information should be recorded, handled, and stored in a way that allows accurate reporting, interpretation, and verification
• Records identifying trial subjects should be maintained confidentially

Post-Research Access and Benefit Sharing

• Post-research access refers to the continued availability of interventions (e.g., drugs, vaccines) to trial participants after the trial has ended, particularly if the intervention proved beneficial
• Benefit-sharing involves providing benefits to the community or population from which the research participants were drawn
• These benefits can include healthcare improvements, infrastructure development, or other resources that address local needs
• Ethical considerations mandate that researchers plan for post-research access and benefit-sharing during the study design phase
• This is especially important in resource-limited settings where trial participants may not otherwise have access to the interventions studied
• The terms of access and benefit-sharing should be agreed upon in advance with the community and participants
• Agreements should be documented in the informed consent process

Quality Assurance (QA) and Quality Control (QC)

• Quality Assurance (QA) focuses on preventing defects
• Quality Control (QC) focuses on identifying defects
• QA encompasses the systematic processes used to ensure the quality of a product or service
• In clinical research, QA involves establishing and maintaining a quality system to ensure that the trial is performed and the data are generated, recorded, and reported in compliance with GCP and applicable regulatory requirements
• Key QA activities include developing standard operating procedures (SOPs), conducting audits, and providing training to research staff
• QC involves the techniques and activities used to verify that the requirements for quality are fulfilled
• In clinical research, QC involves monitoring the trial conduct to detect errors or deviations
• Key QC activities include source data verification, data validation, and review of study documents
• Both QA and QC are essential for ensuring the integrity and reliability of clinical trial data
