How to Ensure Patient Safety in Clinical Trials (2023)?
The clinical trials landscape in 2023 is marked by significant potential for medical advancements, but it continues to confront a persistent challenge: ensuring patient safety.
Safety concerns are a primary contributing factor to the failure of clinical trials. According to Hwang et al., an analysis of failed phase 3 trials revealed that 17% of these failures were attributed to patient safety issues.
This article unravels the complexities surrounding patient safety goals in clinical studies, exploring the importance, contributing elements, challenges, and potential solutions that contribute to conducting safe and effective clinical trials.
Why is Patient Safety Important in Clinical Trials?
Patient safety is a vital point for consideration in clinical trials for a number of reasons, including:
Protecting Participants from Harm:
Clinical trials involve experimental treatments, meaning there is always some risk of adverse effects. However, it is crucial to minimize these risks as much as possible and to ensure that the control group is fully informed of the potential risks and benefits before they enroll in a trial.
Ensuring the Reliability of the Results:
If participants are not safe in a clinical trial, the results may not be reliable. This is because adverse events can interfere with the study’s ability to measure the actual effects of the treatment being studied.
Maintaining Public Trust in Clinical Research:
Clinical trials are essential for developing new and improved treatments for diseases. However, public trust in clinical research is vital, and this trust can be eroded if participants are not adequately protected.
Ethical and Legal Obligations:
Clinical trial sponsors, vendors, investigators, and regulatory bodies have ethical and legal obligations to protect participants from harm. Failing to do so not only undermines the integrity of the trial but can result in severe consequences, including legal liabilities and damage to the reputation of the individuals and organizations involved.
Informed Consent:
Potential trial participants must be fully informed about the experimental nature of the treatment, potential risks, and expected benefits. They should clearly understand what they are signing up for, empowering them to make an educated decision about whether or not to participate in a clinical trial.
Are Clinical Trials Safe?
The Safety of clinical trials is a complex matter. Clinical trials are designed with a focus on patient safety, and numerous safeguards and regulations are in place to minimize risks. However, they are not entirely without risk, as they involve testing experimental treatments. The level of Safety in research studies varies, depending on factors like the nature of the treatment, the trial’s design, and the diligence of researchers and institutions in adhering to safety protocols.
Each clinical trial that the health authorities consider must be reviewed by ethics committees and scientists from relevant fields before patient recruitment and enrollment. Participating in any clinical trial stage ensures patients’ safety through the informed consent procedure, meticulous evaluation and authorization of the clinical trial protocol, and continuous monitoring.
What are the Potential Risks of Participating in Clinical Research?
Adverse events and side effects are the two primary risks in clinical trials.
Adverse Events:
An adverse event (AE) is an undesirable or harmful medical occurrence or symptom that happens to a person during or after using a medication, a medical device, or participation in a clinical trial. Adverse and serious adverse events are closely monitored and reported in clinical trials and healthcare settings to assess the safety and potential risks associated with a particular treatment or intervention.
Side Effects:
Side effects in clinical trials are unintended effects of a new drug or medical device that are experienced by participants in the trial. They can be mild, moderate, or severe and go away independently or require treatment.
The key difference between side effects and adverse events in clinical trials is that side effects are generally considered to be mild and expected, while adverse events can be more severe or unexpected.
How is Safety Assessed in Clinical Trials?
Various organizations and clinical trial elements stand behind assessing patient safety in clinical trials:
Institutional review boards (IRBs):
Institutional Review Boards (IRBs), also known as Ethics Review Boards (ERBs) or Research Ethics Boards (REBs) in some regions, are independent committees responsible for reviewing and overseeing research involving human participants to ensure their rights, safety, and well-being are protected.
Before commencement, researchers must submit the clinical trial protocol, outlining the study comprehensively, to the IRB for assessment. The IRB’s role is to determine the study’s significance, ensure that it addresses a meaningful research question, and guarantee trial participants’ safety.
Data safety monitoring boards (DSMBs):
Data Safety Monitoring Boards (DSMBs) are commonly employed in phase III clinical trials and, in some cases, earlier phases. Their primary role is to monitor the evolution and outcomes of the clinical trial closely. The DSMB possesses the authority to stop a clinical trial in the following circumstances at an early stage, in case of safety concerns arousal, so that none of the trial participants are exposed to critical health damage or when it becomes evident that the new treatment demonstrates a significantly higher (or lower) level of efficacy, such that it necessitates providing the superior treatment,/medication/medical device to all individuals participating in the clinical trial.
The Clinical Trial Investigator:
Clinical trial investigators have a multifaceted role in safeguarding the safety of trial participants. Their responsibilities encompass study design, informed consent, ongoing safety monitoring, and adverse event reporting. The principal investigator educates participants on recognizing and reporting adverse events, promptly communicates with regulatory authorities, and ensures compliance with ethical and regulatory guidelines.
Government Agencies:
Government agencies like the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) are pivotal in upholding patient safety in clinical trials. Their regulatory oversight involves stringent approval processes, ongoing monitoring, and inspections to ensure trials meet the highest safety and efficacy standards. These agencies also facilitate reporting adverse events, which is vital for risk assessment and safety management. Post-market surveillance further extends their commitment to safety by continuously monitoring treatments once they’re on the market. Through guidance, collaboration, and dedicated commitment to safety, EMA, FDA, and their counterparts worldwide are central to the ethical and secure progression of medical research and patient well-being.
