Week 2 - Good Clinical Practice Flashcards
What are clinical studies required for? Give a specific example of a type of study and its use
- Determine the safety and effectiveness of health and medical product
- Randomised controlled clinical trials address scientific and health care questions, which has assisted our knowledge concerning the safety and efficacy of specific products.
- Randomised controlled trials form the basis for evidence-based medicine.
When can randomised controlled clinical trials be considered credible?
What is the term for this? Give an overview
- Only credible if it is conducted according to the fundamental principles known as “Good Clinical Research Practice” (GCP).
- GCP is an international set of ethical and quality standards that applies to clinical trials involving the participation of human subjects.
- GCP compliance provides the general public and the health authorities, with assurance of the integrity and the validity of the data produced in clinical trial experiments.
What are the GCP standards intented for?
Give an exception
- Intended to produce data for marketing authorisation procedures, which can be for new pharmaceutical/ medicinal products or can be an extended form of research for marketed products already established.
- A general exception is academic research using established marketed products, with no intention to produce data for marketing authorisation purposes.
Briefly outline the history of GCP
- In the late 1960s, the WHO created a Scientific Group on Principles for Clinical Evaluation of Drugs.
- The Scientific Group was responsible for assessing regulations for clinical evaluation of drug products, for both new and old marketed drugs, including considerations for new dosage forms, concerning marketed products.
- Another WHO Scientific Group formed in 1975, to address all aspects of the evaluation and testing of drugs and to create standard guidelines for clinical research
- These reports form the foundation for WHO’s ‘Guidelines for good clinical practice (GCP)’ concerning trials on pharmaceutical drugs, which was published in 1995. Following this, several international guidelines were convened.
What does research conducted according to the GCP guidelines ensure?
- Research conducted in compliance with GCP helps ensure the integrity and welfare of the human research participants were upheld and the results produced from the research are valid and accurate.
Define the following GCP terms:
Sponsor
Investigator
Monitoring
SOP
- Sponsor: A person, company, or institution, who are accountable for the management and/ or financing of a clinical trial
- Investigator: person who is accountable for the conduct of the clinical trial. Principal investigator is appointed if multiple investigators are involved at the trial site.
- Monitoring: The act of supervising a clinical trial to ensure that it is carried out in accordance to the study plan, standard operating procedures (SOPs), GCP and regulatory requirements.
- SOP: set of written detailed instructions to attain consistency in the performance, of a given task
Define the GCP term “audit”
- An independent assessment of all trial associated documents and activities in order to identify if the trial was conducted, recorded, and evaluated according to the study plan, GCP regulations and SOPs. The audit procedure is independent of the monitoring procedure.
Describe a Clinical Trial Protocol
- Clinical trials must be described in a succinct, detailed protocol.
- Often the sponsor and the clinical investigators design the study protocol.
- Factors that need to be considered when designing the protocl include: statistical methodology, confounding variables, risk factors, control groups, and study design.
- need to abide to any national regulations concerning the design and conduct of the clinical trial.
Who, in a clinical trial, needs to adhere to SOPs?
- All people supervising clinical research such as the sponsors, contract research organisations, clinical investigators, Independent Ethics Committees (IECs) / institutional review Boards (IRBs), should adhere to SOPs
Who should prepare SOPs for clinical trails and who should they prepare them for?
- Project sponsors should prepare SOPs for:
- Creating and adapting the protocol and other documentations such as case report forms (CRFs).
- Supplies, shipping, handling of the trial product.
- Regulating trial activities to ensure that the data is accurately generated.
- Ensuring that processes are routinely followed and that experimental activities are recorded.
- Auditing to establish whether processes are conducted effectively and the systems for quality control are functioning.
With regards the regulation of clinical trials, what SOPs should be developed? What should it contain?
- Regulators of the clinical trial are recommended to develop standard procedures concerning the activities relating to the regulation of clinical research.
- This document may include safety reports, GCP inspections and sanctions specific to the individuals who defy the national regulations.
Describe the support systems and tools for a clinical trail, what they are for & what they include.
- Suitable support systems and equipment assist the performance of the study and the collection of the experimental data.
- Support systems and tools include, checklists, specification sheets, drug accountability records and trial-related credentials.
Who is responsible for managing the accessibility to support systems and tools? Give some examples
- The sponsor is accountable for managing the accessibility of support systems and tools. For example, the sponsor may consider acquiring:
- Diagnostic equipment
- Computer software
- Software validation systems
- Communication equipment
- Training equipment
What are trial related credentials? What is their purpose and what may they include?
- Developing trial-related documentations serve to assist the progress of the study, including the collection and reporting of the experimental data and analysis of the results
- Trial-related documentation may include:
- Consent documents
- Checklists
- Documentation concerning the supplier of the investigational compound, the amount given to the participants, disposal instructions of any unused product
- CRFs
- Safety documents
- Expenses and funding documents
Describe how personnel and trail sites are assigned to clinical trails
- Clinical trials require qualified and experienced investigators to conduct the study. Sponsors are required to allocate suitable clinical investigators who have the required expertise.
Describe the ethics committee review of a clinical trail
- According to GCP, clinical studies must be appraised and be given approval from IEC/ IRB before recruiting participants.
- Usually, the investigator is accountable for obtaining IEC/ IRB approval of the study protocol, which is subsequently given to the sponsor.
Describe how clinical trials are assessed by regulatory authorities
- According to GCP, clinical studies are obliged to undergo assessment by regulatory aunthorites for the experimental use of the investigational compound in human subjects and to ensure that the study has been effectively designed to address the main objectives of the study, with compliance to the national regulations.
- The sponsor is usually responsible for ensuring that the relevant regulatory authorities review and approve the design of the study.
Describe the process of enrollment of participants into a clinical trial
- The clinical investigator is responsible for the recruitment of the participants for the study.
- They have the responsibility of ensuring that only eligible participants are enrolled in the study and obtaining relevant documentations e.g. the consent forms.
Describe the “investigational product” with regards a clinical trial and who is responsible fr regulating access to the investigational compound
- Quality of the investigational compound is guaranteed by compliance with Good Manufacturing Practice (GMP) and by managing the product according to the manufacturing specifications and the study protocol.
- in accordance to GCP, sponsors regulate access permitted to the investigational compound.
- GCP also requires that the clinical investigators mange the receipt, administration and disposal of the investigational product.
Describe “trial data attainment” with regards clinical trials
- Clinical research must be conducted in conferring to the approved protocol and regulatory obligations.
- Documenting each trial-related activity enables clinical verification that the study have been performed in compliance with the protocol.
Describe “safety management” with regards clinical trials
- The clinical investigator is accountable for informing the sponsor and the IEC/IRB to contrary events, observed during the course of the study.
- The sponsor has the responsibility for reporting the safety of the study to regulatory authorities and other investigational organisations.
- In some circumstances, the Data and Safety Monitoring Board (DSMB) may be assigned by the sponsor to aid overall safety management.
Describe the monitoring of a clinical trial
- In order to assure that a high quality trial experiments are being performed, sponsors may perform set monitoring tasks, which can be done directly or via a contract research organisation (CRO).
- Depending on the type of study conducted, the sponsor dictates the extent and type of monitoring needed.
Describe how trial data is supervised
- Managing clinical trial data effectively ensures that the data sets are complete, reliable and processed in an appropriate manner, which ensures that the integrity and quality of the data is preserved.
- Sponsor is ensures that suitable data management systems are in place.
- Sponsor and the investigator are both accountable for implementing data management systems, thereby ensuring that the integrity of trial data is preserved.
With regards supervising trial data, what should the data management system address?
- Should address the following:
- Data attainment
- Confidentiality
- Completion of CRFs
- Safety data reporting
- Data processing
- Electronic data storage
- Supervision of vendors
