The Procedures Invloved in Clinical Trials
May 20th, 2008 Posted by: admin
Once clinical trials get under way, there are many steps that must be taken to ensure that they are in accordance with the requirements of the United States Food and Drug Administration. It is important to ensure that clinical research trials are as safe and thorough as possible, not only so that the patients who participate are taken care of, but also to be sure that the results are accurate. After collecting a great deal of information from clinical trials healthy volunteers over an extended period of time, such as vital signs, amount of the drug in their blood and whether their health gets better, the data is ready.
The data collected in clinical trials is sent to the study’s sponsor after the research is complete, at which point it is analyzed using a series of statistical tests that have been proven with time. Clinical research trials have a standard set of procedures, but the goals of these trials are not always the same. Clinical trials might be designed to assess the safety and effectiveness of a new medication or device on a specific kind of patient, or assess the safety and effectiveness of a different dose of a medication than is commonly used. Clinical research trials might also assess the safety and effectiveness of an already marketed medication or device for a new indication, or assess whether the new medication or device is more effective for the patient’s condition than the already used, standard medication or device.
In some cases, clinical trials are also used to compare the effectiveness in patients with a specific disease of two or more already approved or common interventions for that disease. Some clinical research trials even compare three or four medications, doses of medications, or devices against each other. In any case, the clinical trials healthy volunteers will be well aware of what the research trial will entail before they agree to participate.
