Abstract

This article illustrates the importance of Good Clinical Practice (GCP), defines and outlines the goals of GCP, presents a historical perspective on GCP and Outlines FDA regulations relating to GCP. Ongoing research shows that whether conducting research involving a new drug, a behavioral intervention, or an interview/survey, Good Clinical Practice (GCP) provides investigators and their study teams with the tools to protect human subjects and collect quality data. In this article, the author will define GCP, explain the benefits of following GCP for all types of human research and clinical trial studies, and provide some resources to assist investigators in implementing the tenets of GCP for their own research studies. This article reviews the impact of Good Clinical Practice (GCP) on clinical trials. GCP is likely to follow the International Conference on Harmonization of GCP guidelines in many aspects. GCP will enforce tighter guidelines on ethical aspects of a clinical study. Higher standards will be required in terms of comprehensive documentation for the clinical protocol, record keeping, training, and facilities including computers. Quality assurance and inspections will ensure that these standards are achieved. The additional requirements of GCP are discussed and any advantage to the study subject. GCP aims to ensure that the studies are scientifically authentic and that the clinical properties of the investigational product are properly documented. In this paper, we address the background history and the events that led up to the formation of these guidelines. Today, the GCP are used in clinical trials throughout the globe with the main aim of protecting and preserving human rights.

Introduction
GCP is a key requirement for anyone involved in the conduct of clinical research is Good Clinical Practice (GCP) training. GCP is the standard and guidelines to which all research is conducted. GCP is a set of internationally-recognized ethical and scientific quality requirements that must be observed throughout the various stages of a clinical trial. Clinical trial following testing in laboratories and animal studies, the most promising treatments is moved into clinical trials [1]. A clinical trial is sometimes called a clinical study [2]. A clinical trial:
• Is a research study that tests how well an intervention works in a group of people
• Tests for new methods of screening, prevention, diagnosis, or therapy
• Is conducted in phases
During a trial, additional information is learned about an intervention, its risks, and its effectiveness and/or efficacy. Trials can only be conducted if there is an uncertainty about the outcome-trials cannot be conducted if the outcome is already known from a previous study [3,4]. Good Clinical Practice (GCP) is one of the basic sets of rules for hospitals, researchers and pharmaceutical companies engaged in clinical [5].
GCP or Good Clinical Practice refers to an international quality standard provided by the ICH for the purpose of regulating clinical trials that involve human subjects. GCP standards offer assurance as to the effect and safety of compounds developed in clinical trials, human rights protection of trial participants, and also define the roles of clinical research investigators, clinical trial sponsors and clinical research associates.
The fundamental tenet of GCP is that in research on man, the interest of science and society should never take precedence over considerations related to the well being of the study subject [5]. It aims to ensure that the studies are scientifically and ethically sound and that the clinical properties of the pharmaceutical substances under investigation are properly documented. The guidelines seek to establish two cardinal principles: protection of the rights of human subjects and authenticity of biomedical data generated. It ensures that the studies are implemented and reported in such a manner that there is public assurance that the data are credible, accurate and that the rights, integrity and confidentiality of the subjects are protected.
ICH-GCP
The objective of this ICH GCP Guideline [6] is to provide a unified standard for the European Union (EU), Japan and the United States to facilitate the mutual acceptance of clinical data by the regulatory authorities in these jurisdictions. The International conference on harmonization of technical requirements for registration of pharmaceuticals for human use (ICH) [7,8] is unique in bringing together the regulatory authorities and pharmaceutical industry of Europe, Japan and the US to discuss scientific and technical aspects of drug registration. The guideline was developed with consideration of the current good clinical practices of the European Union, Japan, and the United States, as well as those of Australia, Canada, the Nordic countries and the World Health Organization (WHO). This guideline should be followed when generating clinical trial data that are intended to be submitted to regulatory authorities. The principles established in this guideline may also be applied to other clinical investigations that may have an impact on the safety and well-being of human subjects [9]. The objective of such harmonization is a more economical use of human, animal and material resources, and the elimination of unnecessary delay in the global development and availability of new medicines whilst maintaining safeguards on quality, safety and efficacy, and regulatory obligations to protect public health [10-12].
Clinical studies should be carried out according to International Conference on Harmonisation (ICH)/WHO Good Clinical Practice standards [13]. This provides a unified standard for the European Union (EU) [14,15], Japan, and the United States, as well as those of Australia, Canada, the Nordic countries and the World Health Organisation (WHO). Thus, any country that adopts this guideline technically follows this same standard. The purpose is to make recommendations on ways to achieve greater harmonization in the interpretation and application of technical guidelines and requirements for product registration in order to reduce or obviate the need to duplicate the testing carried out during the research and development of new medicines.
Principles of GCP
1. The rights, safety and well-being of the trial subjects shall prevail over the interests of science and society.
2. Each individual involved in conducting a trial shall be qualified by education, training and experience to perform his 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. The medical care given to, and medical decisions made on behalf of, subjects shall always be the responsibility of an appropriately qualified doctor or, when appropriate, of a qualified dentist.
12. 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.
13. 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.
14. Provision has been made for insurance or indemnity to cover the liability of the investigator and sponsor which may arise in relation to the clinical trial.
Overview of the Clinical Research Process
Key trial activities include
• Development of the trial protocol

Conclusion
Ongoing research shows that whether conducting research involving a new drug, a behavioral intervention, or an interview/survey, Good Clinical Practice (GCP) [19-24] provides investigators and their study teams with the tools to protect human subjects and collect quality data. In this article, the author will define GCP, explain the benefits of following GCP for all types of human research studies, and provide some resources to assist investigators in implementing the tenets of GCP for their own research studies. This article illustrates the importance of Good Clinical Practice (GCP), defined and outlined the goals of GCP, Presented a historical perspective on GCP, Outlined FDA regulations relating to GCP.
According to Van Dongen [4] ultimately it is not difficult for investigators and their study teams to follow GCP – it is simply a question of writing down procedures, documenting what is being done, and preparing for inspection. He goes on to say that there are considerable rewards, not the least of which is the confidence that the data was obtained through a GCP-compliant research study. GCP will enforce tighter guidelines on ethical aspects of a clinical study. Higher standards will be required in terms of comprehensive documentation for the clinical protocol, record keeping, training, and facilities including computers. The additional requirements of GCP are discussed and any advantage to the study subject. GCP aims to ensure that the studies are scientifically authentic and that the clinical properties of the investigational product are properly documented. In this paper, we address the background history and the events that led up to the formation of these guidelines. Today, the GCP are used in clinical trials throughout the globe with the main aim of protecting and preserving human rights. Quality assurance and inspections will ensure that these standards are achieved. This article reviews the impact of Good Clinical Practice (GCP) on clinical trials.
