What are Good Clinical Practices ?
•More than any one document •Collective compilation of many • thoughts, • ideas and• learning moments
spanning the globe over
•International ethical and scientific quality standard for •Design,•Conduct, •Performance, •Monitoring, •Auditing, •Recording, •Analysis, and •Reporting
of clinical trials

The death sentences imposed in October 1946 were carried out by Master Sergeant John C. Woods (1903-50), who told a reporter from Time magazine that he was proud of his work. "The way I look at this hanging job, somebody has to do it . . . ten men in 103 minutes. That's fast work."

Nazi physician Carl Clauberg who performed medical experiments on prisoners in Block 10 of the Auschwitz camp. Poland, between 1941 and 1944.
A prisoner in a compression chamber loses consciousness (and later dies) during an experiment to determine altitudes at which aircraft crews could survive without oxygen. Dachau, Germany, 1942.
Victim of a medical experiment immersed in freezing water at the Dachau concentration camp. Dachau, Germany, between August 1942 and May 1943.
A Romani (Gypsy) victim of Nazi medical experiments to make seawater potable. Dachau concentration camp, Germany, 1944.

Nuremberg Code (1947)
•Voluntary consent of the human subject is absolutely essential
•Favorable risk/benefit ratio
•Research must help society
•Research should be based on previous knowledge
•Participant must be free to stop at any time
•Research should not cause mental & physical suffering
•Research should avoid risk of injury & death
Declaration of Helsinki (1964)
•Well being of subject > interest of science & society
•Consent should be in writing
•Limited use of placebo
•Greater access to benefit
(April, 1979)
Respect for persons
•Protecting autonomy of subjects
•Treating subjects with courtesy and respect
•Allowing for informed consent
Beneficence
•The philosophy of "Do no harm”
•Maximize benefits for the research project
•Minimize risks to the research subjects
Justice
•Ensure considered procedures are administered fairly
•Fair distribution between•Burden of research (Costs)•Benefit of research
Common Rule (1981)
•Describes the types of research subject(s)
•Defines key terms such as •Research, •Human subject, and •Minimal risk
•Sets forth requirements for •IRB membership•Review procedures•Criteria for approval
•Lists requirements for informed consent
Overview of Clinical research process
Development of the trial protocol
Development of standard operating procedures (SOPs)
Development of support systems and tools
Selection of trial sites and the selection of properly qualified, trained, and experienced investigators and study personnel
Ethics committee review & approval of the protocol
Enrollment of subjects into the study:-
Recruitment,
Eligibility, &
Informed consent
Review by regulatory authorities
Safety management and reporting
Trial data acquisition: conducting the trial
The investigational product(s): quality, handling and accounting
Monitoring the trial
Quality assurance of the trial performance and data
Managing trial data
Reporting the trial
WHO principles for GCP
Principle 1 – Ethical Conduct
•Research involving humans Scientifically sound
In accordance with Declaration of Helsinki
Principle 2: Protocol
•Research
To be described in a •Clear,•Detailed, and•“Scientifically justified” protocol
Principle 3: Risk Identification
•Foreseeable risks and discomforts and any anticipated benefit(s)
To be identified
Principle 4: Benefit-Risk Assessment
•Research initiated only if anticipated benefit(s) outweigh the risks
•Most important considerations•Rights,•Safety, and•Well-being of trial subjects
Principle 5: Review by IEC/IRB
•Research should receive independent (IEC/IRB) approval prior to initiation
Principle 6: Protocol Compliance
•Research Conducted in compliance with the approved protocol
Principle 7: Informed Consent
•To be obtained •From every subject •Prior to research participation •In accordance with national culture(s) and requirements
Principle 8: Continuing review / ongoing benefit-risk assessment
•Research Continued only if the benefit-risk profile remains favorable
Principle 9: Investigator Qualifications
•Qualified and duly licensedmedical personnel Responsible for the
medical care of trial subjects
Principle 10: Staff Qualifications
•Each individual involved should be qualified by•Education, •Training, and•Experience
Principle 11: Records

•Reporting,
•Interpretation, and
•Verification

•In accordance with the applicable regulatory requirement(s)
Principle 13: Good Manufacturing Practice(s)
•Investigational products should be •Manufactured, •Handled, and •Stored

Principle 14: Quality Systems
•Systems with procedures that assure the quality of every aspect of the trial should be implemented •Quality control (QC)•Quality assurance (QA)•Quality improvement (QI)
Code of Federal Regulations, Title 21
21 CFR 11: Electronic records and signatures
21 CFR 50: Protection of human subjects

ICH-GCP guidelines
•“Bible” of clinical trials
•Global law which safeguards humanity
•13 core principles
Who is responsible for GCP ?
•Each & every person involved in the research process.
•This includes
1.Sponsors
2.Investigators and research staff
3. Contract Research Organizations
4. IRB/EC
5. FDA
6. Research Subject
Never ending debate
•Whether the "greater good" trumps the rights of the individual?
•Are individual’s rights what make up the greater good?
•Is it the greater good that allows for individual’s rights?
Take Home Message
•"If it wasn't documented, it wasn't done.”
•GCP is more than a piece of paper or a set of rules
•A mind-set of dedication that ensures a high level of ethics & quality in research
