Are Trials on Humans Secure?
Clinical trials are studies designed to test new medications, products, or procedures in people. In the United States, these trials play a crucial role in advancing medical research and ensuring the safety and efficacy of treatments.
Every clinical trial has an Institutional Review Board (IRB) that ensures the trial is legal, ethical, and well-designed, and includes a safety plan. The IRB is a necessary component of any clinical trial that studies an FDA-regulated drug, product, or device, or if it's funded or carried out by the federal government. Not every trial has an IRB, but its presence is essential for maintaining the integrity and safety of the research.
The main institutions responsible for overseeing patient safety policies in clinical trials are the Food and Drug Administration (FDA) and the Office for Human Research Protections (OHRP). These entities enforce regulations to protect participants and ensure ethical standards in clinical research. Additionally, Institutional Review Boards (IRBs) monitor individual clinical trials for safety compliance.
Researchers must report certain types of clinical research to Clinicaltrials.gov, an online database of studies and their outcomes. This database allows the public to access information about ongoing and completed clinical trials, helping to increase transparency and accountability in the research process.
Clinical trials come in various phases, each with a specific purpose. Phase 1 trials involve testing a new drug or treatment on a small group of regular volunteers without the disease or condition, usually between 20 and 80 people. Phase 2 trials involve a larger group of people, usually in the hundreds, including people with the disease or condition, to assess the safety of the medication or intervention. Phase 3 trials involve thousands of participants to make sure the treatment works and to identify most of the common side effects, comparing it to other medications for the same condition. Phase 4 trials are conducted after FDA approval and public marketing, to get more data on the treatment's effects in various populations.
Some trials set up a Data and Safety Monitoring Board (DSMB) to review data from the research, with a specific focus on patient safety. The DSMB can recommend a trial stop if there's evidence that the trial causes harm.
Clinical trials can use placebos, which are pills or interventions with no active ingredient or benefit but appear to be a genuine treatment, to compare the effectiveness of an intervention versus no intervention and the placebo effect.
It's important to note that trial participation is voluntary, but volunteers tend to be mostly white and older. Greater diversity in trials can help improve the quality of the results, as medications and interventions affect people of different backgrounds and traits differently. The FDA encourages people of underrepresented and historically marginalized groups to take part in clinical trials.
Your information in clinical trials is protected by the Health Insurance Portability and Accountability Act of 1996 (HIPAA), a federal law creating national standards to protect sensitive patient health information.
For those interested in participating in clinical trials, the National Library of Medicine has a search tool to help find trials that are recruiting or may be recruiting in the future.
In conclusion, clinical trials are a vital part of medical research, ensuring the safety and efficacy of new treatments. By understanding the role of IRBs, DSMBs, and the FDA, as well as the importance of diversity in clinical trials, individuals can make informed decisions about participating in these studies and contribute to the advancement of medical science.
