Q

What are the 11 components of the International Council of Harmonisation GCP guidelines?

A
  1. The rights, safety, and well-being of the trial subjects should take priority over interests of science and society.
  2. Each individual involved in conducting a trial shall be qualified by education, training and
    experience to perform their tasks.
  3. Clinical trials shall be scientifically sound and guided by ethical principles in all their aspects.
  4. The necessary procedures to secure the quality of every aspect of the trial shall be
    complied with.
  5. The available non-clinical and clinical information on an investigational medicinal product shall be adequate to support the proposed clinical trial.
  6. Clinical trials shall be conducted in accordance with the principles of the Declaration of
    Helsinki.
  7. The protocol shall provide for the definition of inclusion and exclusion of subjects
    participating in a clinical trial, monitoring and publication policy.
  8. The investigator and sponsor shall consider all relevant guidance with respect to commencing and conducting a clinical trial.
  9. All clinical information shall be recorded, handled and stored in such a way that it can be accurately reported, interpreted and verified, while the confidentiality of records of the trial subjects remains protected.
  10. Before the trial is initiated, foreseeable risks and inconveniences have been weighed against the anticipated benefit for the individual trial subject and other present and future
    patients. A trial should be initiated and continued only if the anticipated benefits justify the risks.
  11. A trial shall be initiated only if an ethics committee and the licensing authority comes to the conclusion that the anticipated therapeutic and public health benefits justify the risks and
    may be continued only if compliance with this requirement is permanently monitored.
  12. The rights of each subject to physical and mental integrity, to privacy and to the
    protection of the data concerning him in accordance with the Data Protection Act 1998 are
    safeguarded.
  13. Provision has been made for insurance or indemnity to cover the liability of the
    investigator and sponsor that may arise in relation to the clinical trial.

Q

Why do we need Good Clinical Practice?

A

Before the implementation of ICH GCP guidelines, there were various disastrous events which occurred due to the lack of ethical and legal regulations preventing physicians from doing patient harm. For example, the ‘Tuskegee Syphilis Study’ in 1932 involved researchers aiming to assess the progression of untreated syphilis in black men. However no informed consent was received, they did not receive the treatment that they needed, and participants were bribed to take part, being told they could have free medical exams and free meals. The trial went on for 40 years. Furthermore, the Pfizer antibiotic trial in Nigeria occurred in 1996. 100 Nigerian children were treated with Trovan to determine its effectiveness, but 11 children died, others suffered brain damage, paralysis or deafness. Pfizer had not gained Nigerian government approval therefore involuntary experimentation had occurred.

Q

What is research governance and what is its purpose?

A

Research governance is defined as a range of regulations and principles which exist to improve standards and quality of research across all aspects of health and social care. The purpose is to safeguard research participants, protect researchers and enhance the ethical and scientific quality of the research. As a result, risk should be minimised and good practice is promoted. Also ensures patient confidentiality and data protection.

Q

List the steps required for approval of a typical clinical trial involving patients.

A

As the project is classified as research, will firstly need approval from HRA. Then you would need NHS R&D Approval and REC approval (via an IRAS Form). Would also need Clinical Trial Authorisation (CTA).

Q

Name examples of Research Sites.

A

You can have sites for various activities of the clinical trial, e.g. patient recruitment, informed consent. These may not occur in the same place as the research activities, e.g. these may occur in a University setting, but research activities may occur in the Toxicology Unit of the Newcastle RVI.

17
Q

What is peer-review in the research authorisation of clinical trials?

A

Peer review refers to the scrutiny of a clinical trial protocol by independent experts to ensure only high quality research is carried out. Either the funder or the sponsor must acquire this.

18
Q

Name the risk assessments that are required for studies.

A

Patient Safety Assessment, Financial Risk Assessment, Organisation Risk Assessment (sponsorship, insurance and indemnity, Investigator/Research Staff Risk Assessment, Scientific Risk Assessment (scientific quality of the research via good design, etc.)

19
Q

What is insurance and indemnity and why is it required?

A

For a clinical trial, insurance and indemnity must be set up by the Sponsor to ensure there is compensation available for patients if any harm is to be suffer after involvement of the research trial.

20
Q

What is a Research Passport

A

A research passport is the mechanism for non-NHS staff to obtain an honorary research contract to conduct research in the NHS. It provides a set of checks on the researcher and allows a faster study start up.

21
Q

What is the Institutional Review Boards and what are their roles?

A

Institutional Review Boards are the ethics committees in the USA which receive ethical applications for the conduct of clinical trials. IRB must approve or reject applications for ethical approval, as well as monitor and audit whether trials in place are abiding by the ethical and legal regulations to protect patients from physiological and psychological harm.

22
Q

When evaluating research proposals, what do IRBs look at?

A

These ethics committees will evaluate the proposal of research and how patients may be affected, the emergency use of consent methodology, the investigator qualifications, subject compensation plans, the study consent materials (consent forms, recruitment forms, study outline forms, etc.) They also ensure that once the study is underway, there are no deviations (if so, these must be approved). They must also ensure that documents are kept for at least 5 years after trial close-out.

23
Q

What is informed consent?

A

This is the ethical and legal obligation to obtain voluntary consent from a patient, after all aspects of the trial have been explained, and the patient has had time to contemplate their participation.

24
Q

Why is informed consent important?

A

All persons are entitled to their own right make their own decisions about whether they wish to receive treatment or not, even if it could be life-saving. Patients also have the right to withdraw the consent at any time. Failure to achieve this is a serious criminal offence, and in the past has led to trials which have had debilitating consequences to the patient. It is ultimately the principal investigators responsibility to obtain informed consent from the patient.

25
Q

How is informed consent achieved?

A

The patient must be competent to provide consent. The consent must be given voluntarily without coercion, and the patient must be fully informed of the following:

  1. The nature of the treatment and investigation.
  2. Why the investigation is required.
  3. How the procedure for the treatment will be performed.
  4. Risks and benefits of the treatments.
  5. Alternative treatments that are currently available.
  6. The likely success of the treatment.
26
Q

What is ctIMP

A

This is ‘Clinical Trials for Investigational Medicinal Products’ and are regulated by the MHRA in the UK.

27
Q

What are the approval requirements for a ctIMP?

A

Before conducting trials, ctIMPs must be registered with the EU Clinical Trials Directive to obtain an EudraCT number. A Clinical Trial Authorisation must then be obtained from the MHRA through IRAS.

28
Q

What is the essential documentation needed for Clinical Trials?

A

Must have the Trial Master File (TMF) and Investigator Site File (ISF). The TMF must be in place throughout the whole duration of the study, and should include evidence to prove compliance with GCP, ethics, patient safety, and trial integrity. Will include the responsibility delegations, the timetabling, and evidence of investigator qualifications. The ISF document should be in place at each research site to prove that the study is being conducted in accordance with regulations, protocol, etc. This document may contain patient identification details, however this must NOT be shared with anyone. Also require source documentation to prove that data has been recorded, measured, and analysed correctly (no false data produced). There must also be evidence of monitoring through the clinical trial period.

29
Q

What is the Mental Capacity Act

A

This is an act which assesses patient capability of giving informed consent via a single, clear test. This aims to protect patients who may be deemed as incompetent. Physicians may make the decision on your behalf, as long as they are acting in the best interest of the patient. Carers or family members may be consulted, however they cannot make decisions for the patient unless this is pre-specified.

30
Q

What is the Human Tissue Act?

A

This is an act which governs the removal, handling, and storage, use, and disposal of human bodies, organs, and tissues from the living and deceased. Consent to tissue use is required.

31
Q

What tissues are not included under the Human Tissue Act?

A

Excluded under the act are embryos outside the human body, cultured cells which have divided outside the human body, artificially created embryonic stem cells, cell lines, extracted DNA, plasma extracted DNA and nails from the living. Regardless, an ethics review is required, even if approval from the Human Tissue Act is not necessary.

32
Q

What is the Caldicott principles?

A

These are principles set out to control the protection of patient data. Any collected data is protected under the Data Protection Act and Caldicott approval MUST be given for any study involving patient data. If patient identifiable information is going to be used, then it must be only be used when strictly necessary, and access to the PII is on a strictly need to know basis.

33
Q

What is IRAS?

A

IRAS stands for Integrated Research Application System. Ultimately, it is a web based system for obtaining approval for research applications.

34
Q

What regulatory bodies are included in the IRAS?

A

NHS R&D Approval, MHRA, NHS REC approval and some others. Approval will still be needed outside of these regulatory bodies, e.g. Caldicott approval, Human Tissue Act approval. Applications are sent to all the regulatory bodies in IRAS at the same time, not sequentially.
