How do clinical trials function?
Medical trials are research studies in which individuals volunteer to help find answers to specific health-related problems. When done correctly, they are the fastest and safest technique for uncovering innovative medicines and methods to improve health.
A protocol specifies the following: the patient types who may participate; the testing and procedure schedules; the drugs used; the dosages, or amount of the drugs; the duration of the study; and the findings that the researchers hope to derive from the study.
Volunteers must agree to the protocol’s criteria and conditions before they may participate in the study. Similarly, the FDA has stringent criteria that researchers, clinicians, and other medical professionals must follow while handling clinical trials. Individuals who agree to participate are guaranteed the greatest degree of safety under these rules.

Why are clinical trials conducted?
Medical trials are conducted for a number of reasons, including determining whether a new pharmaceutical or device is both beneficial and safe for human use.
- to investigate alternative techniques to employing current, approved medicines or traditional treatments in order to make them more useable, effective, or have fewer side effects.
- to get the information required for the safe use of a treatment in a population for whom it has not previously been tested, such as children.
Who should consider medical trials, and why?
Some people participate in clinical trials because no other (approved) treatment has worked for them or because they are unable to deal with certain side effects. Clinical trials give an option when the standard course of therapy fails. Others participate in clinical trials because they want to learn more about medicine.
Participants from diverse backgrounds are required for clinical studies to improve health equity. Patients who will use the drugs should be represented in clinical trials. This is often false; people of other races and cultures are underrepresented in clinical research. This is problematic since different age groups, races, and ethnic groups may react differently to specific medications. Learn more about the clinical trial diversity initiative from the Office of Minority Health and Health Equity.
In all investigations, eligibility criteria are employed to identify who may participate in a clinical trial. The characteristics considered include age, gender, ailment kind and stage, past treatment history, and other medical conditions. This raises the consistency of the study and the possibility that the researchers will be able to answer to the challenges they set out to examine. As a result, not every candidate for a clinical trial will be accepted.
It is critical to test medications and medical equipment on the persons for whom they are designed. Because different people respond differently to medicines, it is equally critical to do research on a diverse group of people. The FDA aims to ensure that people of various ages, races, ethnicities, and genders participate in clinical investigations. Learn more about the FDA’s attempts to widen the scope of clinical trials.
Where are medical trials conducted?
Clinical trials are held at universities, medical centers, clinics, hospitals, and other Federally or industry-funded research facilities. They can be sponsored by businesses (such as a pharmaceutical company), Federal offices and agencies (such as the National Institutes of Health or the United States Department of Veterans Affairs), or individuals (such as doctors or health care providers).
Is it safe to do medical experiments?
The FDA works hard to protect medical trials participants and ensure that persons have access to reliable information before deciding whether or not to participate in a clinical research. The federal government has created clinical research regulations and guidelines to protect participants from unjustified risks. Although every effort is made to keep participant risks to a minimum, some may be unavoidable since we do not completely understand the medical methods employed in the study.
The government requires that researchers offer prospective participants with all relevant information regarding the trial’s methods. Prior to your involvement in the research, you will be provided an informed consent form that defines your rights as a participant and includes information about the study’s details, including any potential risks. By signing it, you understand that the trial is being done for research purposes and that you have the option to leave at any time. The informed consent method guarantees that you are aware of any known risks associated with the study.
What should I think about before joining in a research trial?
Before joining in a clinical study, learn all you can about it. Discuss your concerns and questions with the medical specialists overseeing the research. Also, discuss the research with your doctor to determine whether it makes sense for you given your current treatment plan. Before joining in the research, make sure you understand the following: What will happen throughout the study; the kind of medical treatment you will get; any related payments; and the benefits and risks of participating.
What role does the FDA play in the approval of new drugs and medical procedures?
The FDA guarantees that medical techniques are effective as well as safe for patients to use. We do not conduct clinical research or develop new remedies. Instead, we have power over those who do. FDA staff members meet with researchers and visit clinical trial study sites to protect patient rights and assure the authenticity and integrity of the data.
Where can I find clinical trials?
Inquiring with your doctor is a great way to find out if there are any clinical trials that would be of interest to you. Other sources of information include:
- Find FDA clinical trials. At clinicaltrials.gov, you may search a database of studies that have received government and commercial support. Learn about each experiment’s aims, eligibility criteria, location details, and contact information.
- Clinicaltrials.gov. Conduct additional in-depth searches.
- Call the National Cancer Institute at 1-800-4-CANCER (1-800-422-6237). Find out about clinical trials for cancer sufferers.
- Call 1-800-TRIALS-A (1-800-874-2572) or go to AIDS Clinical Trials and Information Services (ACTIS) for further information. Disclaimer: This is an external link. Find HIV clinical trials in your area.
- AIDSinfo. Search a database of HIV/AIDS trials financed by the National Institutes of Health’s National Library of Medicine.
What exactly is a placebo, and how do medical trials relate to it?
A placebo is a non-therapeutic pill, liquid, or powder. It’s popularly known as a sugar pill. In clinical investigations, experimental drugs and placebos are often compared to measure therapeutic effectiveness.
Is it feasible that I’ll be given a placebo?
In placebo-controlled clinical trials, patients and their doctors are often uninformed of who is receiving the placebo and how they are being treated with the experimental treatment. Other serious and life-threatening disorders, as well as cancer, often lack placebo control groups in medical trials. Every participant receives the experimental medicine in these instances. Inquire with the research organizer about obtaining a placebo instead of the experimental medicine. Then, consult with your doctor about the best course of action.
How can I find out what stage a drug is in in a medical trial?
Speak with the coordinator to find out what stage the clinical trial is in. Learn more about the different clinical trial phases and whether they are the best option for you.
What happens to drugs that don’t make it through clinical trials?
Most drugs produced via preclinical (animal) research are never tested on humans or reviewed by the FDA. Drug developers employ preclinical research as a starting point for the development process. Learn more about medicine manufacturing.
