Principles of GCP Ethical conduct of trials Trial Benefits should be more than risks Preference for Subjects over science & society Adequacy of pre-existing information Scientific validity of trials Independent review before trial begins Medically qualified care Trained personnel Informed consent Efficient information handling Confidentiality Accountability of investigational drug Quality systems
PRINCIPLES OF ICH GCP Ethical conduct : Clinical trials to be conducted in accordance with ethical principles that have their origin in Declaration of Helsinki. Risk benefit assessment : A trial should be initiated continued ONLY if anticipated benefits justify the risks. Trial subjects over science & society : The rights, safety & well being of the individual trial subject should prevail over interests of science & society. Adequacy of pre-existing information : The available information(from preclinical studies) on investigational product should be adequate to support the clinical trial
Scientific validity : Clinical trials should be scientifically sound & described in clear, detailed protocol. Independent review : The protocol of trial should receive prior approval from IRB / IE before trial is started. Medical qualified care : The medical care given to the trial subjects should be the responsibility of a qualified medical professional. Trained & experienced personnel : Each individual involved in the conduct of trial should be qualified for their respective tasks.
Informed consent : Freely given IC to be obtained from each trial subject. Efficiency of information handling : CT information should be recorded, handled, stored correctly. Confidentiality : Confidentiality of records that could identify subjects should be protected. Drug accountability : Investigational drugs used in trial should be manufactured, handled and stored in accordance with GMP Quality system & procedures : System that ensure quality of every aspect of clinical trial should be implemented.
