Informed consent in clinical research is an ethical and regulatory requirement. A research subject must enter a study voluntarily, be informed about risks and benefits, and understand the difference between investigation and treatment. Subjects must not be coerced into enrolment, nor must they be enticed by exaggerated claims of benefit. Before they can enrol, all potential subjects must agree, in writing, to participate. In addition to ethical and regulatory imperatives, the potential for litigation by subjects further highlights the importance of rigorous adherence to informed consent principles. In this short course we set out the principles and requirements and provide examples of practical issues confronting healthcare professionals and subjects.
New drug development requires major investment in capital, human resources and technical expertise. Strict adherence to regulations on testing and manufacturing standards is also required before a new drug can be marketed. One of the greatest challenges in conducting clinical trials is that of efficiency. As trials become more comprehensive, involving large numbers of participants globally, their duration is prolonged and costs increase. The longer trials last, the shorter is the patent life remaining after market approval and the longer patients must wait for the new product. This short course covers the key components of clinical trials and how these requirements interact with the drug development cycle.
Prevention of contamination is one of the most important goals of GMP. Contamination of product is often difficult to detect, so GMP rules emphasise preventive measures, including: attention to personal health and hygiene, and the wearing of special clothing, by staff; and cleaning and sanitation of premises and equipment. In this short course we set out the basics of GMP requirements in these vital areas.
Good Manufacturing Practice (GMP) is a set of rules for medicines manufacturers to follow so that their products are safe, effective, and of good quality. Everyone who works in a processing, quality control, packaging, or warehouse environment for a pharmaceutical or biotechnology company, or one of their contractors, must understand why GMP is important, how it applies to them, and how to comply with it. This short course explains what GMP is and why it is important, and it gives some lessons from history. It introduces the regulations and guidance documents that are the source of GMP rules. Finally, it touches on regulatory inspections and the consequences that can arise from failure to comply with GMP requirements.
Analytical statistical elements are essential concepts in the design of clinical trials. This analysis helps us to understand whether a conclusion from a study of a sample of the target population applies generally to that population as a whole. In particular, it helps us to answer the question: Did the treatment effect in the given study occur just by chance? The statistical elements of a well-controlled study minimise the chances of drawing the wrong conclusions, by providing clear thresholds for such errors. The basic statistical elements of a clinical trial include eligibility criteria, randomisation, sample size, power, and blinding, and these are discussed in this short course.
Capture and management of clinical trial data is a challenge. The industry is under pressure to obtain and analyse such data more quickly, while maintaining data integrity, so that products can be brought to market sooner. Effective planning and adequate resources can ensure clinical trials yield high quality data within strict timelines and budget requirements, at the same time satisfying regulatory standards. This short course describes the purpose of data capture and explores efficiencies in data management as part of the evolving regulatory landscape.
The demands on quality from clinical trials are increasing. Quantitative aspects of clinical trials, such as the mass of study data to be collected, the multiple investigational sites, and the need to meet predetermined timelines, often supersede qualitative features. Therefore, addressing basic requirements for quality management is essential when preparing a clinical trial. This short course describes the core elements required for the establishment of a clinical trial and provides an overview of the role of the sponsor in supporting and improving trial quality.
Clinical trial protocols are an essential part of clinical trial design. Protocol documents are critical to conducting safe and cost-effective investigations. Protocol documents are large and complex, containing comprehensive information relating to purpose, design and conduct of a clinical trial. Aspects of a protocol include patient eligibility criteria, and treatment specifications. This short course provides an overview of clinical trial protocols. Opportunities to improve a clinical trial protocol for regulatory approval are also discussed.
Clinical trial design establishes the framework upon which the clinical trial process will be conducted, and sets the objectives of the trial. The application for marketing approval, submitted to the regulatory authorities, will provide clinical data reflecting the trial design. Since trial design impacts the whole drug development process and lifecycle, particular care and due diligence is essential. This short course provides an overview of the main types of study design.
The sponsor of a clinical trial takes responsibility for its initiation, management, and/or financing. A sponsor may transfer any or all of the sponsor’s trial-related duties and functions to a contract research organisation, but the ultimate responsibility for the quality and integrity of the trial data always resides with the sponsor. Duties and functions discussed in this short course include trial design, selection of investigators, QA and QC, data handling and record keeping, finance and compensation, regulatory submissions, management of investigational product(s), safety reporting, monitoring, audit, dealing with noncompliance, and clinical trial reports. ICH guideline E6 (revision 2) encourages sponsors to adopt a risk-based approach to managing the quality of trials. We discuss this approach in general, and aspects such as risk-based monitoring in particular.
